Broström ankle ligament repair augmented with suture tape : Results of magnetic resonance imaging evaluation.

The Broström procedure is an established procedure in cases of primary lateral ankle ligament repair (LALR). To improve postoperative stability an augmentation device, InternalBrace™ (Arthrex, Naples, FL) has been introduced. This study evaluates remodelling of the anterior talofibular ligament (ATFL) in patients undergoing atape augmented Broström technique as well as clinical outcomes. In this study 32patients with chronic lateral ankle instability (CLAI) receiving augmented LALR were included. Clinical outcomes were evaluated at aone-time postoperative visit between 12and 18months. A3 T magnetic resonance imaging (MRI) was done to evaluate the morphology of the ATFL. Statistical analysis was completed with the free software and environment Rversion3.6.3 (Bell Laboratories, Murray Hill, NJ, USA) and P-values < 0.05 were considered statistically significant. The mean follow-up time was 15.3 ± 1.8months with areturn to sport time of 4.0 ± 2.4months. The average AOFAS (American Orthopaedic Foot and Ankle Society Score) score was 94.4 ± 7.2, the FAOS (Foot and Ankle Outcome Score) demonstrated 87.3 ± 10.4 points and the FFI (Foot Function Index - 2scores (pain and function score)) was 22.9 ± 20.1 and 15.4 ± 10.4, respectively. The MRI findings demonstrated an average length of the ATFL of 18.6 ± 4.3 mm and the width was 3.6 ± 0.9 mm. Aclear differentiation between the ATFL and the augmentation device could be shown in 28cases. The Fisher's exact test could not depict asignificant correlation between the presence of abone marrow edema and the tension of the augmentation device with alevel of significance of α = 0.05. An anatomical healing tendency of the ligament repair and good integrity of the augmentation device could be shown based on MRI findings. The lateral ligament repair augmented with suture tape is an effective and safe procedure regarding surgical treatment in chronic lateral ankle instability producing good clinical outcome.

Three-dimensional printed custom-made modular talus prosthesis in patients with talus malignant tumor resection

BackgroundTalar malignant tumor is extremely rare. Currently, there are several alternative management options for talus malignant tumor including below-knee amputation, tibio-calcaneal arthrodesis, and homogenous bone transplant while their shortcomings limited the clinical application. Three-dimensional (3D) printed total talus prosthesis in talus lesion was reported as a useful method to reconstruct talus, however, most researches are case reports and its clinical effect remains unclear. Therefore, the current study was to explore the application of 3D printed custom-made modular prosthesis in talus malignant tumor.MethodsWe retrospectively analyzed the patients who received the 3D printed custom-made modular prosthesis treatment due to talus malignant tumor in our hospital from February 2016 to December 2021. The patient's clinical data such as oncology outcome, operation time, and volume of blood loss were recorded. The limb function was evaluated with the Musculoskeletal Tumor Society 93 (MSTS-93) score, The American Orthopedic Foot and Ankle Society (AOFAS) score; the ankle joint ranges of motion as well as the leg length discrepancy were evaluated. Plain radiography and Tomosynthesis-Shimadzu Metal Artefact Reduction Technology (T-SMART) were used to evaluate the position of prosthesis and the osseointegration. Postoperative complications were recorded.ResultsThe average patients’ age and the follow-up period were respectively 31.5 ± 13.1 years; and 54.8 months (range 26–72). The medium operation time was 2.4 ± 0.5 h; the intraoperative blood loss was 131.7 ± 121.4 ml. The mean MSTS-93 and AOFAS score was 26.8 and 88.5 respectively. The average plantar flexion, dorsiflexion, varus, and valgus were 32.5, 9.2, 10.8, and 5.8 degree respectively. One patient had delayed postoperative wound healing. There was no leg length discrepancy observed in any patient and good osseointegration was observed on the interface between the bone and talus prosthesis in all subjects.ConclusionThe modular structure of the prosthesis developed in this study seems to be convenient for prosthesis implantation and screws distribution. And the combination of solid and porous structure improves the initial stability and promotes bone integration. Therefore, 3D printed custom-made modular talus prosthesis could be an alternative option for talus reconstruction in talus malignant tumor patients.

Comparison of pain relief among patients with chronic plantar fasciitis treated with intralesional platelet-rich plasma injection versus corticosteroid injection in a tertiary care centre in Kerala - a prospective study

Background: Aim of the study was to compare pain relief and functional outcome and between intralesional autologous platelet rich plasma injection (PRP) versus corticosteroid injection in the treatment of plantar, and fasciitis by using visual analogue score and American Orthopaedic Foot and Ankle Society (AOFAS) score. Methods: The sample size for the study was 30 patients attending Dr. Somervell Memorial CSI Medical College. Patients were divided into two groups (PRP versus steroid) of 15 each. The study follows a prospective observational design with follow up at 2 weeks, 2 months and 3 months post procedure. The functional outcome of patients in each group was assessed using the visual analog scale and AOFAS score. Results: Post-procedure, a significant decrease in VAS score was seen in patients treated with PRP injection (8.73 to 2.27) than those treated with Steroid injection (8.8 to 3.53). Also, there was a significant improvement in the AOFAS score from 72.73 to 88.67 while for those patients treated with steroid injection, the AOFAS score was comparatively low (65.87 to 82.2). Conclusions: Plantar fasciitis is a prevalent condition in our community, and many treatment options typically offer only temporary relief from symptoms. Intralesional PRP injection emerges as a dependable treatment method that fosters the healing process of the affected fascia, resulting in improved functional outcomes. Our study indicates that a singular administration of platelet-rich plasma injection for plantar fasciitis yields substantial pain relief compared to the local steroid injection.

Clinical observation of sinus tarsi syndrome after lateral ankle sprain

To study the incidence rate of sinus tarsi syndrome after lateral ankle sprain and observe the clinical efficacy of sinus tarsal corticosteroid injections. From January 2021 to Janury 2022, 391 patients with lateral ankle sprain and 88 patients with sinus tarsi syndrome using corticosteroid injections (compound betamethasone 1 ml+ lidocaine hydrochloride 4 ml) were retrospectively analyzed. There were 22 males and 66 females, aged from 29 to 60 years old with an average of (41.00±7.52) years old, duration of the disease from 1 to 12 months with an average of (5.6±4.2) months. The visual analogue scale(VAS) and American Orthopedic Foot and Ankle Society(AOFAS) scores were collected before, 1 month, 3 months, 6 months, and 12 months after treatment. All 88 patients completed a 12-month follow-up. The incidence rate of sinus tarsi syndrome after lateral ankle sprain was 22.5%. One month after treatment, VAS was 1.20±0.89, AOFAS score was 88.70±7.04. Three months after treatment, VAS was 1.60±1.35, AOFAS score was 85.20±10.95. Six months after treatment, VAS 2.35±1.39, AOFAS 80.30±9.75. Twelve months after treatment, VAS was 2.80±1.51, AOFAS score was 79.1±9.94. Significant differences were found before and after treatment at all four time points of follow-up(P<0.05). The results of this study showed that the incidence rate of sinus tarsi syndrome after lateral ankle sprain was 22.5%. Corticosteroid injections were effective in the short term with a 65% recurrence rate of symptoms within 1 year. For patients with no significant long-term effect of conservative treatment, clinicians may explore alternative approaches, including options like ankle arthroscopy.

Ankle arthrodesis through minimally-invasive transfibular approach: a new surgical technique.

The purpose of our work was to demonstrate the surgical technique of ankle arthrodesis using the minimally-invasive transfibular (MITF) approach, which minimizes soft tissue damage and is advantageous for high-risk patients. In this prospective study, a total of 12 patients with end-stage varus ankle osteoarthritis, including high-risk individuals, underwent ankle arthrodesis using the MITF approach. The technique involves a unique osteotomy at the joint space level, minimizing soft tissue detachment from the fibula. The primary outcomes assessed included bony union, time to weight-bearing, correction of varus deformity, and functional outcomes measured by the American Orthopedic Foot and Ankle Society (AOFAS) hindfoot scale. However, the study's limitations encompass a small sample size and the absence of a control group. At 6months post-operation, all patients achieved bony union, with a mean time to union of 13.7 ± 5.2weeks. The average time to initiate weight-bearing without additional support was 11.2 ± 3.8weeks. Preoperative varus deformity (17.08 ± 8.36 degrees) and talar tilt (8.75 ± 4.33 degrees) were successfully corrected, with postoperative alignment within 0-5 degrees of valgus. Functional outcomes showed a significant improvement in AOFAS scores from 37.83 ± 7.79 points preoperatively to 77.42 ± 5.63 points one year after surgery (p = 0.002). Minor complications occurred in two patients, both effectively treated with local therapy and antibiotics. The MITF approach for ankle arthrodesis demonstrates promising results in addressing end-stage varus ankle osteoarthritis, even in high-risk patients. However, the study's limitations highlight the need for a prospective comparative clinical trial with a larger sample size to ascertain the technique's effectiveness and safety definitively.

Effectiveness of transverse double "8"-shaped tension band technique for Lawrence zone Ⅰ fracture of the fifth metatarsal base

To explore the effectiveness of transverse double "8"-shaped tension band technique in the treatment of Lawrence zoneⅠfracture of the 5th metatarsal base. Between February 2019 and October 2021, 15 patients with Lawrence zoneⅠfracture of the 5th metatarsal base were treated with transverse double "8"-shaped tension band technique. There were 8 males and 7 females, with a median age of 40 years (range, 23-59 years). The fractures were caused by sprains. The time from injury to operation was 3-7 days (mean, 4.1 days). X-ray films were taken to observe the fracture healing and the anchor looseness and detachment. The foot function was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) score, and the eversion angle of the calcaneal talus joint. The incisions healed by first intention after operation in 14 cases and the incision healed poorly in 1 case. All patients were followed up 8-12 months (median, 10 months). The imaging examination showed that all fractures healed well, with a healing time of 10-14 weeks (mean, 11.7 weeks). At last follow-up, AOFAS score was 82-100 (median, 98); 13 cases were excellent and 2 cases were good, with an excellent and good rate of 100%. VAS score was 0-3 (median, 1). Three cases had mild limited ankle joint range of motion, while 12 cases had normal range of motion. The eversion angle of the calcaneal talus joint was 25°-32° (median, 30°). The application of transverse double "8"-shaped tension band technique for Lawrence zone Ⅰ fracture of the 5th metatarsal base has advantages such as simple operation, avoidance of secondary operation, and reduction of foreign body sensation, with definite effectiveness.

A prospective study on treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures with interlocking intramedullary nail fixation system

To explore the effectiveness of interlocking intramedullary nail fixation system for Sanders type Ⅱ and Ⅲ calcaneal fractures by comparing with open surgery. Forty patients (40 feet) with Sanders type Ⅱ and Ⅲ calcaneal fractures, who were admitted between May 2020 and December 2022 and met the selection criteria, were included in the study. They were randomly allocated into control group and minimally invasive group using a random number table method, with 20 cases in each group. The patients were treated with the interlocking intramedullary nail fixation system in the minimally invasive group and with steel plate internal fixation via a lateral L-shaped incision in the control group. There was no significant difference between the two groups ( P>0.05) in terms of gender, age, fracture classification and side, cause of injury, time from injury to admission, and preoperative width, length, height, Böhler angle, and Gissane angle of the calcaneus. The operation time, intraoperative blood loss, incision length, hospital stay, fracture healing time, incidence of complications, as well as pre- and post-operative imaging indicators (Böhler angle, Gissane angle, width, height, and length of the calcaneus) and American Orthopaedic Foot and Ankle Society (AOFAS) score of foot were recorded and compared between the two groups. The incision length, operation time, and hospital stay of the minimally invasive group were significantly shorter than those of the control group, and the intraoperative blood loss significantly reduced ( P<0.05). All patients of the two groups were followed up, with the follow-up time of 8-12 months (mean, 10.2 months) in the minimally invasive group and 8-12 months (mean, 10.4 months) in the control group. No complication occurred in the minimally invasive group after operation. One case of incision epidermal necrosis and 1 case of traumatic arthritis occurred in the control group after operation. However, there was no significant difference in the incidence of complications between the two groups ( P>0.05). At last follow-up, the AOFAS score was significantly higher in the minimally invasive group than in the control group ( P<0.05). Imaging examination showed that the calcaneal fractures of the two groups healed, and there was no significant difference in healing time between the two groups ( P>0.05). Compared with preoperative conditions, the Böhler angle and Gissane angle of the calcaneus in the two groups significantly increased, the width narrowed, and the height and length increased at 3 days after operation and the last follow-up, with significant differences ( P<0.05). There was no significant difference between 3 days after operation and last follow-up ( P>0.05). There was no significant difference between the two groups at each time point ( P>0.05). The interlocking intramedullary nail fixation system in treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures has the advantages of minimal trauma, shortened hospital stay, reliable fracture reduction and fixation, and satisfactory foot function recovery.

Comparison of the effectiveness of foot orthosis use in pes planus treatment with combination of kinesio taping

Aims: The aim of this study was to compare the clinical evaluations, disease impact, disability and foot function of symptomatic flexible pes planus (SFPP) deformity patients treated with the University of California at Berkeley Laboratory (UCBL) foot orthosis and Kinesio tape (KT) to those treated only with the UCBL orthosis.&#x0D; Methods: A total of 100 feet in 50 subjects with a mean age of 77.10 months were included in the study. The subjects were divided into two groups: Group 1 (UCBL foot orthosis with KT, n=27) and Group 2 (UCBL-alone, n=23). Group 1 consisted of 27 patients (14 girls, 13 boys) with an average age of 62 months (range: 25 to 165), while Group 2 consisted of 23 patients (10 girls,13 boys) with an average age of 63 months (range: 30 to 166). Various assessments, including American Orthopaedic Foot and Ankle Society (AOFAS) scores, anteroposterior and lateral talocalcaneal and talo-first metatarsal angles, talonavicular angle, calcaneal pitch angle and clinical examinations, were conducted to foot-specific disease activity, and foot function.&#x0D; Results: Group 1 exhibited mild-to-moderate foot disability and impairments, along with low levels of disease activity. Treatment with UCBL orthosis and Kinesio tape led to significant improvements in all AOFAS scores and foot angles. Substantial improvement in AOFAS scores was observed during the follow-up examination, except for the midfoot score.&#x0D; Discussion: The use of UCBL foot orthosis in conjunction with Kinesio tape appears to be a preferable treatment strategy for children and adolescents with SFPP. This combined approach is associated with a lower rate of complications, higher patient comfort levels, and faster improvement in both radiological and clinical findings when compared to the use of the UCBL orthosis alone.

Modified gastro-soleus turn-down flap for chronic or neglected achilles tendon ruptures

BackgroundAchilles’ tendon chronic rupture is a common entity that is usually misdiagnosed or mistreated. Hence, she was presented to us later or with complications affecting her gait. Surgical resection is needed to either bridge the gap or reinforce the strength of the tendon repair.ObjectivesOur study's goal was to assess the clinical results of repairing chronic Achilles’ tendon lesions employing the middle segment of the proximal portion of the tendon (gastro-soleus), as a turn-down flap.MethodsOur prospective interventional single arm study included 18 patients with chronic Achilles’ tendon rupture attending at Al-Azhar university hospitals in Cairo, Egypt from May 2020 to April 2023. Diagnosis of the patients was confirmed by radiographic and clinical investigations. They were all treated with the same open reconstruction procedure using a modified GSF. The average follow-up was 12 months. The results of this study were assessed by the Achilles tendon rupture score (ATRS), American Orthopedic Foot and Ankle Society (AOFAS) score, and capacity to perform repeated heel raises on the affected side.ResultsThe mean operative time was 72.77 min. The median (IQR) time of reconstruction was 10 (8–12) after the injury. The median (IQR) length of flab was 4.5 (4.3–5) 9 (Table 2). No intraoperative complications occurred. The typical follow-up period was 12 months (6–18 months). In terms of the ATRS, we found a significant reduction from 82.8 ± 3 preoperatively to 20.8 ± 6.7 at 12 months postoperatively (P value = 0.001). As regards the AOFAS score, it was increased from 49.5 ± 10 preoperatively to 83.8 ± 8.5 12 months postoperatively (P = 0.001). In terms of the post operative complications, there was no re-rupture. Two patients experienced superficial wound infection which improved with daily dressing and antibiotics. Additionally, two patients had slight ankle stiffness four months after the operation, which improved after programmed rehabilitation at the sixth month.ConclusionThe modified GSTF is a simple, safe, well-tolerated and effective method of treatment with excellent functional results and greater patient content.

Rehabilitation effect of standing bed combined with early anti-gravity running table training on ankle fracture

To explore the clinical effect of standing bed combined with early anti-gravity running table training in the healing and functional recovery of anterior rotation external rotation ankle fractures. Fifty-two patients with ankle fractures of degree III or degree IV of PER admitted to Pingle Orthopaedic and Traumatology Hospital of Shenzhen City between September 2021 and January 2023 were selected for observation, and they were divided into 26 cases in each group according to the method of randomised numerical table into the control group and the observation group. The patients in the control group started the routine rehabilitation treatment on the 1st day after operation, and in the 0–2 weeks after operation, the affected limb was elevated and ankle pump training was carried out; in the 3–6 weeks after operation, joint mobility training, strength training and soft tissue release were carried out; and in the 6–8 weeks after operation, weight-bearing training was increased. The observation group added standing bed training on the 7th postoperative day and anti-gravity running table training on the 28th postoperative day on the basis of the treatment protocol of the control group. Bone density, ankle mobility and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores, pain, ankle mobility and swelling evaluations were compared between the 2 groups before and after 8 weeks of treatment, and the quality scores of bone scabs were compared between the 2 groups after 4 weeks of treatment. There was no statistical significance in the comparison of the items between the two groups before treatment (all P > 0.05), and the difference in the bone scab quality score was not statistically significant after 4 weeks of treatment (P > 0.05), and after 8 weeks of treatment, the bone scab quality score, bone mineral density and AOFAS scores, pain, ankle mobility, and evaluations were higher than those of the control group (all P < 0.05), and there was no significant difference in the degree of swelling (P > 0.05). Standing bed combined with early anti-gravity running table training applied to postoperative patients with PER III or IV degree ankle fracture can reduce the degree of pain and improve the ankle joint function.

Efficacy and Safety of Platelet-Rich Plasma Injection for Chronic Plantar Fasciitis: A Prospective Study on Functional Restoration and Pain Relief.

Background Heel discomfort and functional impairment are frequently caused by plantar fasciitis, and treating it can be extremely difficult for clinicians and occasionally have unfavorable clinical consequences. Recently, platelet-rich plasma (PRP) has been used as an alternative therapy for plantar fasciitis (PF) to reduce heel pain and improve functional restoration. We evaluated the current evidence concerning the efficacy and safety of PRP as a treatment for PF. Methodology This was a hospital-based prospective study on patients with plantar fasciitis with a symptom duration of six months or more with failed conservative therapy. All patients included in the study were assessed clinically and by a visual analog score (VAS) for heel pain, the Ankle-Hindfoot Scale (AHS) component of the American Orthopedic Foot and Ankle Society (AOFAS) and Foot and Ankle Ability Measure (FAAM) scores before injection, and at three weeks, three and six-months post-PRP treatment follow-up. Ultrasonography (USG) measurement of plantar fascia thickness was done pre-injection and at the six-month follow-up for clinical outcomes and any complications. Results The study included 25 patients with plantar fasciitis, with the majority (48%) in the age group of 21-30 years. Females accounted for 64% of the patientswhile males accounted for 36%. Most patients (56%) had a moderately active daily activity level. The study found that 16 patients had bilateral plantar fasciitiswhile nine had unilateral plantar fasciitis. Among the patients with bilateral plantar fasciitis, a total of 32 heels were affectedwhile the 9 patients with unilateral plantar fasciitis had 9 affected heels. Most female patients (75%) had bilateral plantar fasciitiswhile most male patients (56%) had unilateral plantar fasciitis. Before PRP therapy, both male and female patients reported high pain scores on theVASfor both heels. However, after PRP infiltration, the VAS scores significantly decreased at three weeks, three months, and six months post-injection, indicating pain relief. The AOFAS hindfoot and ankle scores and FAAM scores showed improvement over the follow-up period. Both male and female patients experienced significant improvements in functional outcomes, with increases in AOFAS (p-value 0.45) and FAAM scores (p-value 0.31) at three weeks, three months, and six months post-injection compared to baseline. Statistical analysis revealed a significant decrease in pain scores (73% pain relief), as well as significant improvements in AOFAS scores with an average of 22.33 from baseline (mean = 67.75±9.7) to final follow-up (mean = 90.08±7.9) and FAAM scores with an average of 23.72 from baseline (mean = 49.38±5.2) to final follow-up (mean = 73.10±5.2) after PRP infiltration. Conclusion The outcomes of a single dosage of PRP injections demonstrate clinically and statistically substantial improvements in functional outcome scores, plantar fascia thickness evaluated by USG, and VAS scores for heel pain. According to the results of this study, local PRP injection is an effective treatment for chronic plantar fasciitis.

Is Surgical Treatment Necessary for the Treatment of a Jones Fracture?: A Retrospective Study.

Jones fractures are common injuries that can be treated conservatively or surgically. However, the optimal treatment approach remains controversial. This study aimed to compare the clinical outcomes of conservative and operative treatments for Jones fractures and determine whether surgical treatment is necessary. A retrospective study was conducted on 69 patients with Jones fractures treated at our hospital. The patients were divided into 2 groups: conservative (C group; n = 46) and operative (O group; n = 23) treatments. Patients were followed up after 2, 6, and 12 weeks, and every 3 months thereafter. However, outpatient follow-ups were conducted between 8 and 10 weeks as needed. The mean follow-up period was 14.5 weeks (range, 12-24 weeks). In group C, the patients were treated with a non-weight-bearing cast for 4-6 weeks, followed by additional weight-bearing boot immobilization before returning to exercise. In group O, patients were treated surgically using a bicortical screw or intramedullary internal fixation. Time to radiologic union, clinical union, return to sports, visual analog scale (VAS), Foot Function Index-Revised Short Form (FFI-RS), and American Orthopedic Foot and Ankle Society (AOFAS) scores were evaluated. Sixty-nine patients were included in the analysis. There were statistically significant differences in the time to radiologic union and return to sports, VAS score in the second week, and FFI-RS score in the 12th week. In group C, favorable outcomes were observed in terms of the time to return to sports, VAS score in the second week, and FFI-RS score in the 12th week. Contrastingly, in group O, better results were observed in time to radiologic union. The AOFAS score was excellent at the final follow-up, with no significant differences between groups. Complication rates were 10.8% and 13% in groups C and O, respectively. Surgical treatment is sometimes necessary for Jones fractures, but conservative treatment should also be considered because of the favorable outcomes. Conservative treatment can be a good option for patients who are risk-averse and place a high value on fracture healing without surgery.

Role of lateral soft tissues release in percutaneous hallux valgus correction: A medium term retrospective study.

In the field of minimally invasive surgery (MIS) for the treatment of hallux valgus (HV), different techniques have begun to emerge in the literature concerning the distal osteotomy of the first metatarsal bone, the synthesis or not of the metatarsal head, the possible association with lateral soft tissues release (LSTR) and osteotomy of the base of the first phalanx. To evaluate the role of LSTR on percutaneous HV correction, evaluating functional and radiographical results. From January 2012 to May 2016 a total of 396 patients with mild to moderate symptomatic HV treated with the MIS technique were included in this retrospective study. The technique provides no internal fixation (WOS). Patients were divided into the LSTR group and no LSTR group (LSTR N). This surgical procedure (LSTR) was reserved for insufficient HV angle (HVA) correction during fluoroscopic control. Patients were evaluated at each follow-up by two other authors after appropriate training by senior authors (first practitioners). Clinical evaluation was performed before surgery, 6 mo after surgery, and 48 mo follow-up. American Orthopaedic Foot and Ankle Society (AOFAS) and visual analog scale (VAS) score was used to evaluate pain and function, and complications were recorded. In addition, the incidence of relapses and the degree of joint range of motion (ROM) with the association with the LSTR (capsule, adductor tendon, phalanx-sesamoid ligament, and the deep transverse metatarsal ligament) were evaluated. Radiological parameters included HVA and intermetatarsal angle (IMA). Patient satisfaction was assessed. Student t-test and Fisher exact test were used to assess statistical analysis. From our study it is clear that no differences in term of HVA, VAS, IMA correction, rate of complications, and AOFAS score were found between groups, while a significant improvement of the same variables was found in each group between pre and postoperative values. A significant improvement in ROM at 6 mo (P = 0.018) and 48 mo (P = 0.02) of follow-up was found in LSTR N group. Complications were rare in both groups. LSTR procedure on percutaneous HV correction seems to increase postoperative joint stiffness with a comparable incidence of relapse and a low incidence of complications.

Satisfactory outcomes from the double-row fixation procedure for ankle lateral ligaments injury with os subfibulare

BackgroundOssicles of avulsed fractures of the lateral malleolus can result in pain or chronic ankle instability. The purpose of this study was to evaluate and compare the arthroscopic double-row fixation procedure with anatomic ankle lateral ligaments reconstruction for the treatment of ankle lateral ligaments injury with os subfibulare. MethodsThis retrospective study included 38 patients with ankle lateral ligaments injury with concomitant os subfibulare who were treated between July 2016 and November 2021. The patients were divided into a double-row fixation group (n = 19) and an ankle lateral ligaments reconstruction group (n = 19). The Karlsson and Peterson Scoring System for Ankle Function (KAFS), American Orthopedic Foot and Ankle Society (AOFAS) score, Tegner score, visual analog scale (VAS), and anterior drawer test (ADT) were obtained preoperatively and at the last post-operative follow-up. Magnetic resonance imaging (MRI) was also performed at the last post-operative follow-up. ResultsThe KAFS, AOFAS, VAS, and Tegner scores increased significantly after the surgery. Furthermore, the pre- and post-operative functional scores were comparable between the two groups. The ADT was negative in all participants post-operatively. There were no significant differences between the double-row fixation and ligaments reconstruction groups regarding the proportions of patients who achieved a minimally clinically important difference (MCID) in KAFS, AOFAS, and Tegner scores. There was no significant difference in T2 mapping values for the tibial and talar side post-operatively between the two groups. Moreover, there were no significant differences in functional scores post-operatively between bony fusion and non-fusion patients in the double fixation group. ConclusionThe double-row fixation procedure provided similar satisfactory clinical outcomes when compared with lateral ligaments reconstruction for the treatment of ankle lateral ligaments injury with os subfibulare over a short follow-up duration.

Clinical application of 3D printing-assisted patient-specific instrument osteotomy guide in stiff clubfoot: preliminary findings

BackgroundThe orthopedic treatment of the stiff clubfoot is challenging for clinicians, and the purpose of this study was to explore the preliminary findings of 3D printing-assisted patient-specific instrument (PSI) osteotomy guide for use in the orthopedic treatment of the stiff clubfoot.Material and methodsThere were 20 patients (25 feet) with stiff clubfoot admitted from December 2018 to June 2022, including 13 males (16 feet) and 7 females (9 feet), aged 24–52 years, mean 40.15 years; 8 left feet, 7 right feet, 5 bipedal. All patients underwent triple arthrodesis and were divided into 10 cases (12 feet) in the PSI group (n = 12) and 10 cases (13 feet) in the conventional surgery group (n = 13) according to the surgical approach. The duration of surgery and the number of radiation exposures were recorded in all cases, and the American Orthopedic Foot and Ankle Society (AOFAS), and International Congenital Clubfoot Study Group (ICFSG) scoring systems were applied postoperatively to assess the effect of corrective treatment. All measurement data were expressed as mean ± standard deviation, and differences between groups were determined by Student’s t test. All count data between the two groups were compared using the chi-square test or Fisher’s exact test analysis.ResultsAll 20 patients (25 feet) were followed up for 1 year. No major complications related to osteotomy, such as overcorrection, incomplete correction, or bone nonunion, were observed in the PSI and conventional surgery groups at the final follow-up, and the PSI group had the advantage of shorter operative time (P < 0.01), less radiation exposure (P < 0.01), and higher excellent rate compared with the conventional surgery group. The AOFAS score (P > 0.05) and ICFSG score (P > 0.05) at the last follow-up were not statistically significant in both groups, but the excellent rate at the last follow-up was 91.7% in the PSI group which was significantly higher than that of the conventional surgery group at 76.9%.ConclusionsThe utilization of 3D printing-assisted PSI osteotomy guide in orthopedic surgery for stiff clubfoot offers a safe and effective surgical tool for triple joint fusion treatment. This technology simplifies surgical procedures, minimizes intraoperative radiation exposures, reduces surgical time, and enables precise and personalized treatment.

Retrograde tibial intramedullary nail versus minimally invasive locking plate for extra-articular distal tibial fractures: A comparative and retrospective study

BackgroundThe fractures of distal tibia represent common lower limb injuries, frequently accompanied by significant soft tissue damage. The optimal surgical approach for these fractures remains a considerable debate. This study was to perform a comparative analysis of retrograde intramedullary tibial nails (RTN) and minimally invasive plate osteosynthesis (MIPO) for extra-articular distal tibial fractures. Patients and methodsBetween December 2019 and December 2021, a retrospective review was conducted on 48 patients who sustained extra-articular distal tibial fractures. Patients underwent either RTN or MIPO procedures. Operative duration, intraoperative fluoroscopy exposure, time to union, duration until full weight-bearing, American Orthopedic Foot and Ankle Society (AOFAS) scores, and related complications were recorded and compared between the two groups. ResultsNo statistically differences were observed in operative duration, time to union, angulation of the distal tibial coronal plane, or AOFAS scores between RTN and MIPO groups. However, the RTN group had a higher average number of intraoperative fluoroscopy images (8.2 ± 2.3) compared to the MIPO group (4.1 ± 2.0). The RTN group demonstrated shorter average hospital stays (7.1 ± 1.4 days) and a quicker return to full weight-bearing (9.9 ± 1.3 weeks), which were significantly superior to the MIPO group (9.0 ± 2.0 days and 11.5 ± 1.5 weeks, respectively). In terms of complications, the RTN group had one case of superficial infection, whereas the MIPO group exhibited two cases of delayed union and nonunion, one instance of implant failure, two occurrences of deep infection, and an additional three cases of superficial infection. The complications rate was remarkably higher in the MIPO group. ConclusionBoth RTN and MIPO are effective treatment options for extra-articular distal tibial fractures. However, RTN may offer superior outcomes in terms of reduced hospital stay duration, faster return to full weight-bearing capacity, and a lower rate of complications.

Peroneus longus tendon autograft versus allograft in revision ACLR: A retrospective comparison

PurposeThe use of peroneus longus tendon (PLT) autografts in primary anterior cruciate ligament reconstruction (ACLR) has increased recently, but there is a lack of research on its use in revision ACLR. This study aimed to compare the clinical outcomes and complications between revision ACLR using allografts and PLT autografts. Materials and methodsFifty-nine patients who underwent arthroscopic revision of ACLR with complete clinical follow-ups between 2012 and 2021 were retrospectively reviewed. Allograft was used in 44 of these patients, and PLT autograft was used in 15 of them. Lysholm knee score, Tegner activity score, Lachman, and anterior drawer tests were performed after a mean follow-up of 60months (range: 19–116). The American Orthopaedic Foot and Ankle Society (AOFAS) scale was used to evaluate the donor ankle functions. Clinical outcomes and complications were compared between groups. ResultsBoth groups showed significantly improved functional outcomes compared to their preoperative assessments. However, both groups had similar clinical results at the final follow-up, including Lysholm knee score, Tegner activity scale, knee range of motion, return to sports, time to return to daily activities, and rate of re-rupture. No major complications were seen in any of the patients. The AOFAS score was 99.13±2.64 in the PLT autograft group without loss of ankle muscle strength, deformity, instability, and permanent iatrogenic neurovascular injuries. The cumulative cost of the allograft group was significantly higher than the PLT autograft group. ConclusionsThe PLT autograft might be an alternative autograft option to allografts due to similar clinical outcomes, low donor site morbidity, and reduced cost in ACLR revisions, especially if the primary ACLR was performed using grafts harvested around the knee. Level of evidenceIII; retrospective comparative study.

A new method of anterior talofibular ligament reconstruction: Arthroscopically artificial ligament reconstruction with tensional remnant-repair

PurposeTo investigate the clinical effects of arthroscopically artificial ligament reconstruction with tensional remnant-repair in patients who are obese, and/or with demand for highly intensive sports, and/or with poor-quality ligament remnants. MethodsA retrospective case series study was performed on patients treated by arthroscopically anterior talofibular ligament (ATFL) reconstruction with tensional remnant repair technique from January 2019 to August 2021. General data, including demographics, surgical time, and postoperative adverse events, were recorded. The American Orthopaedic Foot and Ankle Society score (AOFAS), foot and ankle ability measure (FAAM), visual analog scale (VAS), and anterior talar translation were measured preoperatively and at 6 weeks, 3 months, and 2 years postoperatively. Ultrasonography examination was performed preoperatively and 2 years postoperatively to evaluate the ATFL. Data were analyzed using SPSS 19.0. F test was used to analyze the pre- and postoperative VAS, FAAM, and AOFAS scores. The significance was set at p < 0.05. ResultsThere were 20 males and 10 females among the patients with a mean age of (30.71 ± 5.81) years. The average surgical time was (40.21 ± 8.59) min. No adverse events were observed after surgery. At 2 years postoperatively, the anterior talar translation test showed grade 0 laxity in all patients. VAS score significantly decreased from preoperatively to 6 weeks, 3 months, and 2 years postoperatively (p < 0.001). Improvement of FAAM score and the AOFAS score from preoperatively to 6 weeks, 3 months, and 2 years postoperatively was statistically significant (p < 0.001). At 3 months postoperatively, most patients (23/30) could return to their pre-injured activities of daily living status. At 2 years postoperatively, all patients were able to return to their pre-injured activities of daily living status, and almost every patient (18/19) who expected highly intensive sports returned to sports with only 1 obese patient failing to achieve the goal. The ultrasonography examination at 2 years postoperatively showed that there was a linear band structure of soft tissue on the tension-rich fiber tape image from the fibular to the talar attachment sits of ATFL. ConclusionThe novel arthroscopically artificial ligament reconstruction with tensional remnant-repair technique for ATFL achieved satisfactory clinical outcomes in the short and medium term after operation, and allowed early return to pre-injured activities, which could be a reliable option for patients with chronic lateral ankle instability.

Vacuum sealing drainage combined with eggshell-like debridement antibiotic-loaded calcium sulphate for calcaneal osteomyelitis

BackgroundTo compare the clinical efficacy of vacuum sealing drainage, eggshell-like debridement combined with antibiotic calcium sulphate implantation and conventional debridement combined with antibiotic calcium sulphate implantation in the treatment of calcaneal osteomyelitis.MethodsSixty-six patients with calcaneal osteomyelitis who were treated in our department between January 2017 and August 2021 were included in this study. Thirty-one patients underwent VSD and eggshell-like debridement combined with antibiotic calcium sulphate implantation. Thirty-five patients underwent conventional debridement combined with antibiotic calcium sulphate implantation. The inflammatory markers, operation time, wound healing time, hospital stay, full weight bearing time after operation, recurrence rate of infection, complications, and American Orthopedic Foot and Ankle Society (AOFAS) scores were compared between the two groups.ResultsThe operation time and full weight bearing time after operation of observation group were longer than that of control group. Compared with preoperative results, WBC, ESR, CRP and PCT in both groups were significantly decreased at 14 days after operation, and there was no statistical significance between the two groups. The wound healing time and hospital stay in the observation group were shorter than those in the control group (P < 0.05). There were four patients with aseptic exudation in the observation group and ten patients with aseptic exudation in the control group, and the wounds healed well after multiple dressing changes. Seven patients in the observation group underwent secondary bone grafting due to bone defects, and four patients in the control group received secondary bone grafting due to bone defects. In the observation group, three patients received debridement combined with antibiotic calcium sulphate implantation again due to recurrent infection, compared with seven patients in the control group. One year after operation, the observation group had a better AOFAS scores than the control group, especially in terms of foot function (P < 0.05).ConclusionCompared with conventional debridement and antibiotic calcium sulphate implantation, VSD and eggshell-like debridement combined with antibiotic calcium sulphate implantation in the treatment of calcaneal osteomyelitis can shorten the wound healing and hospital stay of patients, reduce postoperative aseptic exudation complications and infection recurrence rate, and better preserve the foot function, which is a simple and effective method.

Management of complex pilon fractures: Is it necessary to fix all the columns in AO/OTA type 43-C fractures?

IntroductionSurgical treatment of AO/OTA 43-C pilon fractures has not yet taken a standard form. We aimed to evaluate whether patients that appeared to be labelled as unsupported columns according to the four-column theory would affect long-term clinical and radiological outcomes. Materials and MethodsPatients with AO/OTA 43-C type who were treated surgically between January 2010 and December 2019 were included in the study. 53 fractures in 52 patients who received osteosynthesis were categorized based on the fixed columns. These groups were formed as fully supported columns (FSC- Group A), partly supported columns (PSC-Group B), Ankle range of motions (ROM), Burwell Charnley's reduction evaluation criteria, Kellgren-Lawrence ankle osteoarthritis staging system, and American Orthopedic Foot and Ankle Society (AOFAS) Scoring System, Olerud-Molander Ankle Score, Visual Analog Scale were used for evaluating radiological and functional outcomes. ResultsThe mean follow-up period was 72.6 (12–131) months. Mean age was 42.6 (18–76). Two groups were homogenously distributed in terms of age (p = 0.785), sex (p = 0.376), laterality (p = 0.732), smoking status (p = 0.488) and reduction quality. There was no difference in AOFAS score (p = 0.452), Olerud-Molander score (p = 0.354) and VAS scores (p = 0.589). TAS, TLS and TT angle measurements suggested no difference between groups (p = 0.493, p = 0.834, p = 0.577). There was no difference between groups in terms of infection (p = 0.734), malunion (p = 0.688) and arthritis (p = 0.483) ConclusionWe presented findings that contradicted the hypothesis positing the existence of four distinct columns in pilon fractures, as well as the notion that each fractured column requires support from distinct implants.
