Treatment of proximal phalangeal fracture with miniature combined external fixator

To investigate the clinical effect of limited open reduction treatment of proximal phalangeal fracture with miniature external fixator combined with small incision. Between January 2020 and December 2022, 29 patients with proximal phalangeal fracture were treated with micro external fixator combined with small incision in fracture plane, including 23 males and 6 females, aged from 19 to 62 years old with an average of (36.2±21.0) years old. Five patients with open phalangeal fracture were treated with stageⅠsurgery, 24 cases of closed phalangeal fracture were treated with elective surgery. At the 6 month follow-up, the curative effect was evaluated according to the total active flexion scale (TAFS) of the American Hand Surgery Association. The fracture healing, nail path, local soft tissue healing, and complications were observed. All the 29 patients were followed up for 6 to 10 months with an average of(8.3±2.1) months, 3 patients had delayed fracture healing, 1 patient had distal skin numbness, symptoms were relieved after nutritional nerve treatment, no external fixator broken nails, no infection, the nail path and small incision healing was good, bone healing was achieved at the end of follow-up. Fracture healing time ranged from 10 to 24 with an average of (13.7±3.1) weeks. Six months after operation, according to the TAFS standard, 19 cases (227.68±4.23) were excellent, 7 cases (203.86±14.32) were good, and 3 cases (170.33±7.32) were poor. The micro-combined external fixator combined with limited incision with small incision can be used in the treatment of proximal phalangeal fracture. The operation is simple and beneficial to early functional exercise, small extensor tendon irritation, convenient second-stage removal, and high rate of excellent and good functional score in recovery period.

Effect of groove splint fixation on early swelling and blood flow velocity of the injury limb in elderly patients with distal radius fractures

To observe the effects of groove splint fixation on early hand swelling, blood flow velocity, and clinical function in elderly patients with distal radius fractures. Between March 2021 and February 2022, 64 patients of unilateral closed distal radius fractures were treated with manual reduction and external fixation with splints. There were 10 males and 54 females, the age ranged from 60 to 78 years old, with an average age of (67.7±4.7) years old. According to the order of admission, the patients were divided into the groove splint group and the conventional splint group, with 32 cases in each group. In the groove splint group, there were 4 males and 28 females, with an average age of (68.6±4.8) years old. There were 13 patients with left-sided fractures, and 19 patients with right-sided fractures, with 22 cases classified as AO type A and 10 cases as AO type C. The mean time from injury to treatment was 3.0 (2.0, 4.0) h. In the conventional splint group, there were 6 males and 26 females, with an average age of (66.9 ± 4.4) years old. There were 17 patients with left-sided fractures and 15 patients with right-sided fractures, with 20 cases classified as AO type A and 12 cases as AO type C. The mean time from injury to treatment was 3.0 (2.0, 5.0) h. After manual reduction, patients were treated with groove splint or conventional splint. Swelling, assessed by the difference in limb circumference between the injured and healthy limbs, was measured at 1, 3, 7, and 14 days post-treatment. Blood flow velocities in the superficial palmar arch and dorsal metacarpal veins were measured at 1, 3, and 7 days post-treatment. Radiographic evaluations of radial styloid height, palmar tilt, and ulnar variance were performed preoperatively and 3 months post-treatment. Functional outcomes were assessed using the DASH (Disabilities of the Arm, Shoulder, and Hand) score 3 and 12 months post-treatment. Statistical analyses were conducted to compare the outcomes between the two groups. All 64 patients were followed up for the least 12 months. The swelling value of the palm in the groove splint group [(1.897±0.071) cm, (1.200±0.169) cm, (0.994±0.085) cm] was significantly improved compared to the conventional splint group[(2.283±0.268) cm, (1.893±0.269) cm, (1.183±0.126) cm] on days 3, 7, and 14 days posttreatment, with a statistically significant difference (P<0.001). On the first and third day after splint fixation, the difference in blood flow velocity of the superficial palmar arch in the groove splint group(0.017±0.009), (0.018±0.011) L·min-1 were lower than that in the conventional splint group(0.023±0.011), (0.025±0.013) L·min-1, with statistical significance (P<0.05). On the 3rd and 7th days, the difference was not statistically significant (P>0.05). Comparison of blood flow velocity differences between the dorsal metacarpal vein and the two groups showed no statistically significant difference on the first day after splint fixation (P>0.05). On the 3rd and 7th days, the blood flow velocity difference between the groove splint group[(0.037±0.019), (0.021±0.013) L·min-1] decreased compared to the conventional splint group[(0.062±0.033), (0.037±0.022) L·min-1], and the difference was statistically significant (P<0.05). There was no statistically significant difference in the palm angle, ulnar deviation angle, and radius height of the distal radius before and after reduction (P>0.05). The DASH score showed a statistically significant difference at follow-up 3-month[(6.1±2.8) scores vs (8.2±3.7) scores] , P<0.05, but no statistically significant difference at follow-up 12-month (P>0.05). Fixing distal radius fractures with groove splints in the early stage can reduce the impact on the blood flow velocity of the superficial palmar arch and dorsal palmar vein, reduce venous reflux obstruction and swelling of injury limb, alleviate wrist and finger joint stiffness, and improve early clinical efficacy of the affected limb. However, it has no significant impact on clinical function one year after injury.

Clinical and Functional Outcomes of Knee Arthrodesis by Charnley’s External Fixator

Clinical and Functional Outcomes of Knee Arthrodesis by Charnley’s External Fixator

One-Stage Tibiotalocalcaneal Arthrodesis for Severe Septic Destruction of the Ankle Joint Using a Retrograde Intramedullary Nail: A Retrospective Cross-sectional Study.

Severe septic destruction of the ankle joint poses a therapeutic challenge but lacks a consensus optimal treatment. Tibiotalocalcaneal arthrodesis (TTCA) is considered as a valuable salvage procedure, but the literature remains scarce. Conventional treatment approaches, including 2-stage procedures, have been associated with prolonged recovery times and varying success rates. Many authors prefer classical external fixation in these scenarios, citing concerns that internal implants might pose a risk for recurrent infection. To date, no study has investigated the outcomes of 1-stage surgery using a retrograde intramedullary (IM) nail. The main purpose was to assess the rate of recurrent infection at 2 years following 1-stage TTCA using a retrograde IM nail in severe septic destruction of the ankle joint. Fusion rates and functional outcomes were evaluated as secondary purposes. The clinical and radiologic data of patients who underwent 1-stage TTCA with retrograde IM nail following severe septic destruction of the ankle joint with a minimal follow-up of 2 years were retrospectively analyzed. Reinfection rate, fusion rate, functional outcomes, and complications were evaluated. A total of 25 patients were included with a mean follow-up of 42 months (24-92 months). The mean age was 55 ± 18 years old. At the last follow-up, reinfection occurred in 6 patients (24%) and fusion was obtained in 19 patients (83%). Eight patients (32%) required revision surgery. The mean postoperative modified American Orthopaedic Foot & Ankle Society (AOFAS) score, 12-Item Short Form Health Survey physical and mental component summary scores were respectively 53 ± 19.5, 35.5 ± 11.4, and 46.7 ± 13.5 points. One-stage TTCA with retrograde IM nail appears to be an acceptable alternative in severe septic destruction of the ankle joint, with a high eradication rate of infection and ankle fusion.

'Low-Plane' Fractures of the Distal Humerus in Elderly Patients with Osteoporosis Show High Postoperative Complication Rates.

Background: This study aimed to investigate the fracture patterns and complexity of distal humerus fractures with high-resolution computed tomography (CT) as a function of Dual-Energy X-ray absorptiometry (DXA)-derived bone marrow density (BMD) measurements in an elderly patient cohort. Methods: A retrospective chart review was conducted on patient data collected at a Level I trauma center between January 2007 and January 2022. Inclusion criteria comprised patients aged ≥40 years with a confirmed distal humerus fracture as demonstrated by CT. Additionally, patients were included if they underwent DXA. Patient demographics and detailed information regarding the surgical treatment and trauma mechanism were retrieved from the institutional databank. Fractures were classified as either 'low-plane' distal humeral fractures or 'non-low-plane' distal humerus fractures. Furthermore, the fracture patterns were classified according to established classification systems. Intra- and postoperative complication and revision rates were analyzed. Results: A total of 41 patients (30 women; mean age 74 ± 13 years) were enrolled. Low-energy trauma was sustained by 68% of the patients. The remaining 32% of the fractures involved medium-energy trauma. A total of 62% of the patients underwent primary osteosynthesis, while 30% of patients were initially treated with an external fixator. ORIF was performed in 89% of cases and, in the majority, double-plate osteosynthesis was used (76%). An olecranon osteotomy was performed in 30% of cases. A total of 5% of cases received total elbow arthroplasty, and 10% of cases were treated conservatively. A total of 61% of patients had osteoporosis, 24% of patients had osteopenia, and 15% of patients had a normal BMD with an overall mean T-score of -2.4. Most of the fractures were complex (including 61% Type C fractures). A total of 66% of cases were considered as 'low-plane' fractures. Postoperative complications occurred in 11% of patients (64% of cases among 'low-plane' fractures). Revision surgery was required in 20% of cases. Conclusions: The consecutive series of patients showed a high incidence of 'low-plane' fractures. However, no statistical significance was found between the BMD and fracture complexity. The very distal 'low-plane' fractures showed a high complication rate, which was aggravated by osteoporotic bone conditions. These findings highlight the need for future research with larger patient samples to better understand the relationship between the BMD, fracture complexity, and outcomes in patients with 'low-plane' fractures in order to reduce complications and improve clinical outcomes.

Percutaneous External Fixation of Redistributed Orbital Fat in Transcutaneous Lower Eyelid Blepharoplasty.

While percutaneous external fixation has gained popularity in transconjunctival blepharoplasty due to its simplicity and minimal incision, internal fixation remains the standard approach in transcutaneous blepharoplasty. This study aims to assess the safety and effectiveness of percutaneous external fixation specifically in transcutaneous fat repositioning blepharoplasty. From May 2022 to December 2023, a consecutive cohort of 97 patients underwent this surgical technique. Building upon the principles of transconjunctival fat repositioning, the procedure involved a minimal incision targeting the muscle layer, a conservative release of the tear trough ligament, and the repositioning of fat secured with percutaneous external fixation. Surgical outcomes were evaluated using the Barton grading system and FACE-Q scales for patient-reported outcomes. Following a mean follow-up of 7.2 months (ranging from 6 to 17 months), a resolution of tear trough deformities and eyelid bags was achieved in over 92% of cases. Notably, significant improvements (P < 0.05) were observed in lower eyelid aesthetics as measured by the FACE-Q scale, with a concomitant enhancement in patients' social confidence (P < 0.05). Overall, patients expressed satisfaction with their decision to undergo the procedure (71.0±19.1). Complications necessitating revision surgery included isolated cases of hematoma evacuation, fat injection, excision of excess fat, and skin excision. External fixation in transcutaneous blepharoplasty is technically less complex and minimally invasive, effectively securing transposed fat pedicles safely, presenting a viable alternative to conventional fixation techniques.

Application of Ortho-Bridge System after Femoral Bone Transport.

The bone transport technique uses the principle of distraction-osteogenesis and fill bone defects with the aid of an external fixator. In order to evaluate the clinical effect of femoral internal fixation with Ortho-Bridge System after bone transport, 4 patients after femoral bone transport from October 2020 to October 2022 are studied in this paper. Among them, 3 patients ran refracture of femur after removal of the Limb reconstruction system, 1 patient just finish femoral bone transport and request internal fixation. The surgery results show that Ortho-Bridge System can be used in the situation that conventional Locking compression plate and intramedullary nail are not suitable due to anatomical variation after femoral bone transport. Key words: femoral fracture; Ortho-Bridge System; bone transport; postoperative complications of bone transport.

Surgical correction of posttraumatic triphalangeal joint flexion contractures of the fingers (systematic literature review)

Introduction Triphalangeal joint flexion contracture of the fingers is a common and challeging posttraumatic hand condition. The goal of surgical treatment is to correct finger deformity and increase interphalangeal range of motion.The objective was to systematize data on the causes of post-traumatic triphalangeal joint flexion contracture of the fingers and methods of surgical correction.Material and methods The original literature search was conducted on key resources including Scientific Electronic Library (www.elibrary.ru), the National Library of Medicine (www.pubmed.org), ScienceDirect, Google Scholar, Ovid databases according to PRISMA recommendations. Literature searches included both Russian and English studies, with one or more cases of post-traumatic triphalangeal joint flexion contracture of the fingers with the deformity surgically corrected. Cases of non-traumatic flexion contractures were excluded. Etiological factors of flexion contractures, heterogeneity of definitions and methods for recording the range of motion in the joint, anatomical features, surgical correction of flexion contractures and postoperative complications were reviewed.Results Common causes of flexion contractures included burns (32.3 %), dislocations and fracturedislocations of the finger joints (23.5 %). The median postoperative follow-up period was 13.5 months after surgical treatment. Surgical correction was produced with external fixation device (EFD) in 40 % of cases, open procedures performed in 50 % and a combined technique employed in one case (10 %). Based on calculations of the odds ratios of postoperative complications, a weak positive linear relationship was revealed between EFD and pain syndrome, and a weak negative linear relationship was observed between the open procedure and pain.Discussion There is heterogeneity of approaches regarding methods for correcting flexion contractures, surgical approaches, techniques for mobilizing joints and releasing the anatomical structures of the finger with open procedures, the distraction rate with EFD, methods for repair of soft tissue defects following the treatment of flexion contractures of interphalangeal joint of a finger.Conclusion Open procedures are commonly used for precise elimination of all components of flexion contracture of the joint and repair of soft tissue defects of the finger. A weak positive linear relationship was revealed between EF and pain syndrome. There was no significant correlation between open techniques and complications. There were no correlations between the treatment method and the contracture type; there are no treatment regimens for patients with this pathology.

Temporary osteosynthesis of the tibial bones in repair of multiple and combined injuries

Background The incidence of injury worldwide remains high, with a global estimate of 6763 cases per 00,000 population (95 % confidence interval 6412–7147). Trauma to the limbs is a common injury to an individual anatomical area during multiple or combined trauma that accounts for 40 % to 85.2 % of cases. Assessment of the effectiveness of different fixation options and development of treatment algorithms are essential for patients with tibial fractures and multiple (combined) injuries.The objective was to determine how often temporary tibia fixation is applied for patients with multiple and combined injuries.Material and methods The original literature search was conducted on key resources including Scientific Electronic Library (www.elibrary.ru), the National Library of Medicine (www.pubmed.org), CyberLeninka between 2008 and 2023 using search words and phrases: tibial injuries, osteosynthesis of lower limbs, multiple injuries, combined injuries, temporary osteosynthesis of the tibial bones.Results and discussion A differentiated approach to the repair of bone fractures resulting from multiple and combined injuries is mostly common with the choice of fixation technique depending on the severity of injury and the severity of the patient’s condition. The definitive internal bone fixation is normally used for stable patients, “damage control” strategy is secured for borderline and severe cases using primary temporary external fixation followed by staged surgical intervention. There is no generally accepted strategy for the use of early mobilization of long bone fractures as a component of anti-shock measures in a polytrauma patient.Conclusion Certain issues remain unresolved, including the use of osteosynthesis for tibial fractures in some cohorts of patients, the optimal time of transition to definitive internal fixation, the possibility of using extrafocal osteosynthesis as a definitive treatment, the optimal configuration and assemblies to be employed. The lack of high-quality randomized controlled trials in this field is an important limitation.

Design and analysis of exoskeleton devices for rehabilitation of distal radius fracture.

In this work, the mechanical principles of external fixation and resistance training for the wrist affected by a distal radius fracture (DRF) are revealed. Based on the biomechanical analysis, two wearable exoskeleton devices are proposed to facilitate the DRF rehabilitation progress. Chronologically, the adjustable fixation device (AFD) provides fixed protection and limited mobilization of the fractured wrist in the early stage, while the functional recovery of relevant muscles is achieved by the resistance training device (RTD) in the later stage. According to the designed mechatronic systems of AFD and RTD, the experimental prototypes for these two apparatuses are established. By experiments, the actual motion ranges of AFD are investigated, and the feasibility in monitoring joint angles are validated. Meanwhile, the resistant influences of RTD are analyzed based on the surface electromyography (sEMG) signal features, the results demonstrate that the training-induced muscle strength enhancement is generally increased with the increment in external resistance. The exoskeleton devices presented in this work would be beneficial for the active rehabilitation of patients with DRF.

Effect of patient factors and procedure on proximal tibia fracture recovery - A retrospective analysis

Objective: Tibia plateau fractures account for 1-2% of all fractures and might adversely affect the knee joint. The current research aimed to evaluate the effect of surgical procedures, age, and gender on proximal tibia fracture functional outcomes. Methods: The present data for the retrospective analysis was obtained from an observational longitudinal cohort trauma registry study, initiated at a tertiary care hospital in June 2015. A total of 51 isolated tibia plateau fracture patients were routinely treated with open reduction internal fixation or external fixator and assessed for functional outcomes till twelve months by the Rasmussen scoring scale. Patients were divided into five age groups. The functional outcome association to gender, age groups, and surgical procedures was assessed by the Fisher Exact test and logistic regression analysis. Results: The mean age of the total 51 patients was 40±11 years. Patients operated with Open Reduction and Internal Fixation (74.5%) or with an external fixator (25.5%). Road traffic accidents were the common mechanism of injury. There were non-significantly different functional outcomes observed among age groups or between surgical procedures at all follow-ups but significantly different between genders at three-month follow-ups. Males recovered better than females (p=0.02). Conclusion: Tibia Plateau fracture patients respond almost equally to both external fixation and Open Reduction Internal Fixation procedures. Age does not influence the outcome. However, males had better functional outcomes at three months post-surgery indicating that gender could affect the outcomes. Further exploration might assist in planning gender-based proximal tibia fracture treatment strategies for optimum outcomes. doi: https://doi.org/10.12669/pjms.40.10.9154 How to cite this: Ahmad T, Muhammad ZA, Zehra F.

Ilizarov versus ORIF for Open AO Type-C Pilon Fractures

Objective: This study aimed to evaluate the clinical effectiveness of ORIF versus Ilizarov for the management of Type C closed pilon fractures of the distal tibia at 12 months follow up. Methods: This retrospective cross sectional study was conducted at Jinnah Postgraduate Medical Center (JPMC) between 29th May 2015 and 27th November 2019 that included patients 18 years and older diagnosed with open AO type C pilon fractures. The primary outcome was the patient-reported Disability Rating Index (DRI) months. While the secondary outcomes were quality of life assessment using the patient satisfaction form (SF-12) and AOFAS-Ankle Hindfoot Score. Radiographs were assessed for fracture healing, time to healing, and malalignment. Results: Fifteen patients underwent ORIF, while 26 patients were treated with Ilizarov, there was no statistically significant difference in DRI scores at 12 months between the two groups. In terms of clinical outcomes, both groups had comparable results throughout the follow-up period. The number of unplanned surgical procedures was not statistically significant (p=0.73), 26.92% (n=7) in the Ilizarov as compared to 33.33% (n=5) in the ORIF group. Conclusion: Among patients with an acute, displaced, intra-articular fracture of the distal tibia, neither external fixation nor locking plate fixation resulted in superior disability status at 12 months. Patient factors may need to be considered in deciding the optimal approach. doi: https://doi.org/10.12669/pjms.40.10.8941 How to cite this: Shaikh SA, Tanveer MO, Tahir M, Ahmed N.

Clinical and radiological assessment of the Polish modification of the Ilizarov external fixator for the treatment of intra-articular calcaneal fractures.

There is currently no established gold standard for the treatment of calcaneal fractures. To conduct a clinical and radiological evaluation of patients following intra-articular calcaneal fractures treated with the Polish modification of the Ilizarov method. This was a 2-center retrospective study. We evaluated 27 patients (2 women and 25 men) aged 28-73 years (mean age 50.5 years) after treatment of intra-articular calcaneal fractures with the Polish modification of the Ilizarov method. We assessed pain using a visual analogue scale (VAS), American Orthopedic Foot and Ankle Society (AOFAS) scores, patient satisfaction with treatment, use of analgesics, duration of Ilizarov treatment, length of hospital stay, duration of surgery, patient's declared willingness to choose the same treatment again, complications, degenerative changes, Böhler angle, inflection angle, and Gissane angle. The mean follow-up period was 3 years and 2 months. Following treatment, the mean VAS pain score was 2.3. Prior to surgery, all patients were taking analgesics in comparison with only 2 patients (7.4%) at long-term follow-up. The treatment was rated as satisfactory by 11 patients, with 16 patients rating it as highly satisfactory. The mean post-treatment AOFAS score was 76.6 points. The Ilizarov fixator was removed after a mean period of 88 days. The mean duration of hospital stay was 7.4 days. The mean duration of the procedure was 44 min. All patients would choose the same treatment again. Complications were observed in 5 patients. The long-term follow-up visit revealed degenerative changes in the talocalcaneal joint in 8 patients. The median Böhler angle was 5.5° preoperatively and 28.5° postoperatively, p < 0.001. The median preoperative inflection angle of 160° decreased to 145°, p < 0.001. The median preoperative Gissane's angle of 119° increased significantly to a median postoperative value of 143°, p < 0.001. The patients achieved good clinical and radiological outcomes.

Pseudoaneurysm of the Lingual Artery in a Patient With Facial Trauma From Gunshot Wounds

A pseudoaneurysm is an abnormal dilatation within the wall of a blood vessel due to the formation of a hematoma in the vessel wall after vessel injury. Because of the protective nature of the facial skeleton and the deep location of the lingual artery, the lingual artery pseudoaneurysm is rare. The authors report a case of a 20-year-old male who suffered multiple gunshot wounds, including to the mouth, presenting with immediate life-threatening injuries. On hospital day 1, otolaryngology performed debridement of the mandible, retrieval and removal of bullet fragments, intermaxillary fixation, external fixation of the mandible, intra-oral laceration repair, repair of tongue laceration, and tracheotomy revision. On postoperative day 15, the otolaryngology service was called for the abrupt onset of major oral cavity bleeding. computed tomography-angiogram detected a pseudoaneurysm of the lingual artery and was successfully treated with endovascular coil embolization.

Surgical Treatment of Periarticular Distal Radius Fracture in Elderly: A Systematic Review

Background/Objectives: The treatment of periarticular distal radius fractures remains challenging. Different surgical treatment options have been proposed as alternatives to conservative treatment. This systematic review aims to compare the functional outcomes, radiological outcomes, and complications among volar locking plates (VLPs), Kirschner-wire fixations, and external fixations (EFs) for distal radius fractures in patients aged 60 years and older. Methods: We conducted a comprehensive search of PubMed, Cochrane, and Science Direct databases assessing the effects of VLP, EF, and K-wire treatments for distal radius fractures in patients aged 60 years and over. The primary outcome was the evaluation of the range of motion (ROM) degrees after three surgical procedures, trying to assess the best treatment option. The secondary outcome included evaluation of the Disabilities of the Arm, Shoulder, and Hand (DASH) score, quick-DASH score, Patient-Rated Wrist Evaluation (PRWE) score, Visual Analog Scale (VAS) score, grip strength, radiographic assessment, and complications comparing VLPs, EFs and K-wires. Results: A total of 23 studies were included, comparing VLP, EF, and K-wire fixation. The overall population comprised 5618 patients, with 4690 females and 1015 males, of which 4468 patients were treated with VLP, 503 with EF, and 647 with K-wire. The most common complications among the VLP group were complex regional pain syndrome (7.5%) and carpal tunnel syndrome (6.8%); for the EF group, infections (9.8%) and carpal tunnel syndrome (6.8%); and for the K-wire group, carpal tunnel syndrome (7.5%) and infections (6.9%). Conclusions: VLP showed better clinical outcomes in the first few months after treatment. However, these differences decreased over time and became similar after one year. EF and K-wire fixations remain easier to manage during surgery.

New strategy for shortening the consolidation period in distraction lengthening of phalanges or metacarpal bone

Distraction lengthening of digits enhances hand function in patients with congenital phalangeal defects or traumatic hand amputations. Although callotasis is a useful distraction lengthening method, it is challenging and often results in various complications and prolonged fixation. Based on our experiences, we attempted to develop innovations to reduce the fixation period. We included 12 digits from nine patients with digital bone defects; lengthening was performed on seven proximal phalanges and five metacarpal bones using an Ilizarov mini-fixator device. In three digits, cancellous bone grafting within the cavity of the distraction callus, concomitant with internal fixation using an intramedullary screw, was performed to shorten the Healing Index. The mean achieved lengthening was 24mm for proximal phalanges and 22mm for metacarpal bones, with a Healing Index of 37.9 and 42.6 days/cm, respectively. Additionally, the Healing Index was significantly shorter in the three digits treated with cancellous bone grafting and internal fixation (mean 27.0 days/cm) than in the nine with no bone grafting (mean 44.1 days/cm). Major complications included early bone union, insufficient fingertip skin, and callus fractures during the consolidation period, affecting two, two, and one patient, respectively. Bone grafting within the distraction callus cavity promotes rapid bone formation, while internal fixation enables earlier removal of external fixators, thereby shortening the Healing Index.

Intramedullary nailing of coated and uncoated nails in infected tibial pseudarthrosis : Results of aretrospective examination of 56patients

In surgery for sepsis it is a well-established principle that no internal osteosynthetic material should be implanted in cases of chronic osteomyelitis. Therefore, the surgical treatment with intramedullary nails is so far used only rarely in cases of chronic osteomyelitis. This study analyzed whether the implantation of tibial intramedullary nails is an effective treatment for chronic osteomyelitis and how high is the rate of reinfection. A retrospective analysis of patients with an infected pseudarthrosis of the tibia in whom agentamycin-coated nail (ETN) or an uncoated tibial intramedullary nail (UCN) was implanted between December 2011 and December 2019 was carried out. The preoperative, perioperative and postoperative results were evaluated. During the study period 29 patients received a UCN and 27 patients received an ETN. Of the patients 95% (n = 53) had been previously unsuccessfully treated with external fixation. Postoperative complications occurred in 45% of the patients and more often in the ETN group (48% vs.41%). Reexacerbation of the infection occurred in 20 patients and more frequently in the UCN group (38% vs. 33%). The nonunion already showed abony consolidation at the time of the exacerbation in 10patients (50%). At the end of the follow-up aconsolidation was present in 48patients (86%), more frequently in the UCN group (90% vs.78%). Of the patients 50 (89%) reached full weight bearing without any differences between the groups. Despite arelatively high arate of postoperative complications the risk of reinfection was acceptable with good functional and radiological results. The main general advantages of nailing are without doubt the high primary stability, the implantation with preservation of the soft tissue and the improved wearing comfort for patients.

Differentiated Approach to Surgical ­Treatment of Gunshot Diaphyseal Shin Fractures

Background. The roots of problems in the treatment of gunshot fractures to extremities lay in the high-energetic character of these traumas, the frequency of infectious complications, high rate of slow consolidations, and occurrence of pseudoarthroses and bone tissue lesions. Objective. The objective of the study was to improve the treatment results of patients with gunshot fractures of the shin bones based on the development of a differentiated approach to the treatment of such injuries. Material and Methods. The study is based on the results of examination and treatment of 128 patients with dominant combat shin traumas. The patients were divided into two groups. The first group (control group) included 68 patients who underwent treatment with an external fixation device (EFD). The second group (study group) included 60 patients who underwent the extrafocal osteosynthesis replaced by an internal, mostly intramedullary one. To assess the functional outcomes of treatment, we applied the LEFS (Lower Extremity Functional Scale) in the dynamics of the therapy, namely in 3, 6, 12, and 18 months after the injury. Results. Mean values in both groups during the first two to three weeks showed no statistically significant difference, and their average score according to the LEFS scale was 15.75 points. The most significant differences were observed in the period from 6 to 12 months after the injury, 39.4±2.4 (EFD) and 57.3±2.1 (intramedullary nailing). After 18 months, excellent results showed 20.7% of patients from the study group and 15.8% of the control group (61 – 80 LEFS scores). Good results had 43.2% and 33.1%, respectively (41 – 60 LEFS scores). 28.1% and 39.3%, respectively, showed satisfactory results (21 – 40 LEFS scores). Poor results showed 8.0% of patients of the study group and 11.8% of the control group (p&lt;0.05). Conclusions. The analysis of treatment outcomes of patients with gunshot diaphyseal shin fractures demonstrates that conversion, when used according to indications and following criteria to the replacement of the method of fixation, reduces the incidence of complications in both the early and late postoperative periods, fastens consolidation of gunshot diaphyseal shin fractures by 4.5±2.3 weeks, reduces the frequency of fracture consolidation disorders by 10.6%, and improves the functional results of the patients by 15.0%.

ANALYSIS OF OPEN REDUCTION AND INTERNAL FIXATION (ORIF) IN COLLES' FRACTURE

Colles fracture, first described in 1814, is characterized by the dorsal displacement of the distal radius fragment and is highly prevalent, particularly among elderly patients. This study aims to evaluate the effectiveness of Open Reduction and Internal Fixation (ORIF) in treating Colles fractures, focusing on functional outcomes and postoperative quality of life. An integrative literature review and comparative analysis of studies on ORIF and other treatment methods were conducted using Google Scholar, Scopus, and Web of Science as indexing tools. Articles were selected using the keywords “Colles Fracture, Open Reduction and Internal Fixation, Functional Outcomes, Postoperative Complications.” The review highlights that ORIF generally provides superior functional outcomes and fewer complications in various fractures, such as those of the humerus, tibial pilon, calcaneus, and unstable distal radius fractures, compared to less invasive methods like external fixation (EF). However, EF shows advantages in specific cases, such as shorter surgical time and fewer perioperative complications. Moreover, the studies indicate that risk factors like diabetes, fracture severity, lack of drainage, and bone graft usage increase the risk of complications in ORIF. Additionally, minimally invasive techniques can reduce pain and enhance functional recovery in certain fractures, such as patellar fractures, when compared to ORIF.
