Arthroscopic Eden-Hybinette procedure with Triple-Pulley and four point anti-rotation fixation technique for recurrent anterior dislocation of shoulder joint

To explore effectiveness of arthroscopic Eden-Hybinette procedure with Triple-Pulley and four point anti-rotation fixation technique in the treatment of recurrent anterior dislocation of shoulder joint. A clinical data of 14 patients with recurrent anterior dislocation of shoulder joint and glenoid bone defect, who were met the selective criteria and admitted between February 2021 and February 2022, was retrospectively analyzed. All patients were treated with arthroscopic Eden-Hybinette procedure and the bone blocks were fixed by using Triple-Pulley and four point anti-rotation fixation technique. There were 9 males and 5 females with an average age of 31.2 years (range, 22-40 years). Shoulder dislocation occurred 4-10 times (mean, 6.8 times). The time from the initial dislocation to the admission was 1-6 years (mean, 3.3 years). The Instability Severity Index Score (ISIS) was 7.2±0.8, the Beighton score was 2.9±2.4, and the width ratio of glenoid bone defect was 26.64%±1.86%. Pre- and post-operative visual analogue scale (VAS) score, the University of Califonia-Los Angeles (UCLA) shoulder score, Constant score, and American Association of Shoulder and Elbow Surgeons (ASES) score were used to evaluate shoulder pain and function. The position, healing, resorption, and remodeling (glenoid area) of the bone blocks were evaluated by CT of shoulder joint. All patients underwent surgery successfully without any serious complications. All patients were followed up 11.5-13.8 months (mean, 12.0 months). The VAS scores of shoulder joint after operation decreased compared to preoperative levels, while the UCLA score, Constant score, and ASES score all increased, with significant differences ( P<0.05). And with the prolongation of time, the above indicators further improved, and the differences between different time points were significant ( P<0.05). Imaging reexamination showed that the bone block completely filled the glenoid defect, with good position and no significant displacement. Over time, the bone block healed and partially absorbed and remodelled. The postoperative glenoid area increased significantly compared to preoperative area ( P<0.05). With the prolongation of time, the glenoid area significantly decreased, but the difference was not significant between different time points ( P>0.05). For the recurrent anterior dislocation of shoulder joint, Triple-Pulley and four point anti-rotation fixation technique in Eden-Hybinette procedure can effectively prevent bone rotation, make fixation more reliable, and easy to operate and achieve good effectiveness.

EFFECT OF KYPHOPLASTY ON PAIN CONTROL AND VERTEBRAL RESTORATION.

Numerous studies have been conducted regarding vertebral restoration, development of kyphotic deformity, and pain control following balloon kyphoplasty. However, there is no consensus regarding the ideal time to perform kyphoplasty. Herein, we aimed to compare the results of treatment of different vertebral levels following early or late kyphoplasty. Between 2017 and 2022, 283 patients with single-level osteoporotic vertebral fractures were retrospectively reviewed. 100 patients who attended regular postoperative follow-ups, visual analog scale (VAS) values were recorded, and osteoporosis tests were performed were included in the study. Traumatic single-level fractures in patients with osteoporosis who were aged >60 years were included in the study. Patients with a history of malignancy, previous spinal surgery, or neurological deficits were not included in the study. A total of 50 patients underwent kyphoplasty within 3 days of sustaining the fracture (Group 1), and 50 patients underwent kyphoplasty more than 3 after sustaining the fracture (Group 2). Groups A, B, and C included fractures at the T7-T11 levels, T12-L1 levels (thoracolumbar junction), and L2-L5 levels, respectively. These groups were compared among themselves. Bilateral balloon kyphoplasty was performed under sedation in the prone position. Preoperative and postoperative VAS scores, anterior vertebral heights (AVH), and kyphotic angles (KA) were measured and recorded. The vertebral segments that underwent early and late kyphoplasty were also compared among themselves. In all the patients who underwent early or late kyphoplasty, there was a significant decrease in the kyphotic angle and a significant increase in vertebral heights during the early postoperative period (p < 0.001). There was no significant change in the vertebral heights and kyphotic angle between the early and late postoperative periods (p = 0.780). Early kyphoplasty demonstrated better pain control with a greater improvement in VAS score (p < 0.001) than late kyphoplasty. Kyphoplasty plays an important role in reducing pain and ensuring early mobilization in older patients. In our study, the improvements in both symptoms and radiologic features are concrete evidences in favor of performing early kyphoplasty.

Comparison of electronic apex locator and simultaneous working length detection methods with radiological method in terms of postoperative pain

BackgroundPrecise knowledge of the apical construction, which determines the end of the area for canal preparation and filling, is essential for the success of root canal treatment and the management of postoperative pain. For this purpose, devices based on various methods that determine the working length (WL) are used. However, it is still controversial which method provides the most accurate measurements.AimTo investigate the compatibility of the electronic apex locator (EWL) and simultaneous working length determination (SWL) methods in single-root teeth in comparison with the radiographic working length determination (RWL) method and to determine which one produced more effective results in terms of postoperative pain.Materials & methodsOne hundred patients scheduled for root canal treatment (RCT) were randomly assigned to one of the three groups according to the working length measurement method (EWL, SWL or RWL). After WL determination with assigned method, root canals were prepared and then obturated. Age, gender, simplified oral hygiene index (OHI-S), oral and dental examinations and Visual Analogue Scale (VAS) results of all participants were recorded. The incidence and intensity of postoperative pain were rated on a Visual Analogue Scale (VAS) by patients 6, 12, 24, 48 h and 7 days after RCT. The number of analgesic tablets (400 mg Ibuprofen) taken by patients was also recorded. Data were analyzed using the chi-square, One- way ANOVA and Kruskal-Wallis tests. Bland-Altman and Passing-Bablock regression analysis were used as method comparison techniques.ResultsIt was determined that the number of patients receiving analgesia and the total number of analgesia doses were higher in EWL and RWL groups compared to SWL group (p < 0.0001). When the WL values at which the treatment was applied were compared in the patient groups; WL values of EWL group were statistically lower than SWL group (p < 0.01). While there was no difference between the preoperative VAS scores of the groups (p = 0.7590), the postoperative 6th and 12th hour VAS scores of SWL group were lower than those of EWL and RWL groups (p = 0.005 and p = 0.0002, respectively). Again, the VAS scores of SWL group at the 24th and 48th postoperative hours were lower than those of RWL group (p < 0.05). According to the Bland-Altman and Passing-Bablock regression analysis results, although there was no statistically significant difference between the EWL and SWL methods (p = 0.471), the bias value of -0.1190 was well below the acceptable total error (0.1648). Additionally, a strong relationship was found between EWL and SWL methods (r = 0.9698, r2 = 0.9406, p < 0.001). Therefore, statistically these two methods were considered compatible with each other. It was determined that there was a statistically significant bias (0.340, p < 0.0001) between the RWL and SWL methods, exceeding the total error.ConclusionsAs a result, it was determined that the SWL method, which is used to determine working length for the success of endodontic treatment, can be used as an alternative to the EWL method thus producing more effective results in the management of postoperative pain. However, in addition to the method used, the technology of the device developed for this method should not be ignored.Clinical relevancePrecise knowledge of the apical construction, which determines the end of the area for canal preparation and filling, is essential for the success of root canal treatment and the management of postoperative pain. For this purpose, devices based on various methods that determine the working length are used. However, it is still controversial which method provides the most accurate measurements. This study found that the simultaneous working length determination method can be used as an alternative to the electronic working length determination method and produces more effective results in the management of postoperative pain. Another important outcome of this study is that the Total Allowable Error (TEa) for the electronic apex locator method, which is accepted as the reference, has been calculated for the first time. Other methods have been evaluated according to this reference method. This is a first in literature.

Reconstruction of radial deviation after preaxial polydactyly surgery: use of an ulnar fascial flap.

Radial deviation of the interphalangeal (IP) joint is a common complication of treating Wassel type IV-D preaxial polydactyly. Long-term radial deviation can place excessive tension on the radial skin and cause overabundance of the ulnar skin. To overcome this problem, we aimed to utilize a fascial flap for ulnar reconstruction of a defect in the radial skin. We used a fascial flap for ulnar reconstruction of a defect in the radial skin, eight patients (average: 12 years, range: 5-33 years) who underwent reconstructive surgery at our department for radial deviation of the interphalangeal (IP) joint after the initial operation were included between August 2017 and August 2021. An incision was made on the radial side of the thumb. An olive-shaped flap was designed on the ulnar eminence of the IP joint. The skin and fascia in the other three quadrants were incised. While the flap was protected, children with epiphyseal plates underwent wedge osteotomy at the maximum ulnar deviation of the proximal phalanx, and adults underwent direct fusion of the distal IP joint. Absorbable sutures were used to suture the flap. The Tada functional and visual analog scale (VAS) scores were recorded before and after the operation. All flaps survived without infection or necrosis. The preoperative and postoperative Tada scores were 1 and 5, respectively, and the preoperative and postoperative VAS scores were 3 and 9, respectively. The postoperative scores showed a statistically significant degree of improvement. An ulnar fascial flap is an effective and feasible option for repair of radial deviation following surgery for preaxial polydactyly.

Outcomes of repaired and intact rotator cable in large posterosuperior rotator cuff ruptures.

This study aimed to compare the clinical and functional outcomes of patients with large posterosuperior rotator cuff tears between those with intact rotator cables (crescent-shaped tears) and those with repaired rotator cables (U-, V-, or L-shaped tears). Eighty-two patients with a mean age of 64.05 ± 9.06 years who underwent arthroscopic repair due to large posterosuperior rotator cuff tears were evaluated with a follow-up period of 32 ± 5.9 months. Forty-two patients with an intact rotator cable and 40 patients with a repaired rotator cable (rotator cable restored with tendon-tendon sutures) were evaluated regarding preoperative and postoperative pain and functional outcomes. There was no significant difference in the constant score between the rotator cable repaired and the intact group (P=.22). However, when the sub-dimensions of the Constant score were compared separately, the forward flexion was significantly higher in the group with the intact rotator cable (P=.002). When the postoperative visual analog scale (VAS) scores were compared, lower scores were observed in the group with the repaired rotator cable (P < .001). In large posterosuperior rotator cuff tears, patients with a repaired rotator cables experienced more significant pain relief compared to those with intact rotator cables, although their forward flexion was lower. Therefore, a detailed analysis of the tear type and the rotator cable condition in large posterosuperior rotator cuff tears may help predict postoperative pain and functional outcomes. Level III case-control study.

The effect of intravenous lidocaine infusion on subarachnoid anesthesia in patients undergoing total knee replacement: a randomised controlled trial.

Intravenous lidocaine is a non-opioid analgesic adjunct for perioperative pain relief. The aim of our study was to explore whether concurrent administration of intravenous lidocaine prolongs the duration of sensory block during total knee replacement (TKR) under spinal anaesthesia. This prospective randomized double blind controlled trial was conducted on 28 patients (14 in lidocaine group and 14 in the control group) undergoing unilateral TKR under spinal anesthesia. In the lidocaine group, intravenous lidocaine 1.5mg·kg-1 followed by an infusion of 1.5mg·kg-1·h-1 was administered intraoperatively after spinal anesthesia. The primary outcome was the duration of sensory block of spinal anesthesia. Secondary outcomes included onset time of sensory and motor block, duration of motor block, time to first postoperative analgesic, postoperative visual analog scale (VAS) scores and postoperative analgesia requirement in 24h after surgery. The duration of sensory and motor block was longer in the lidocaine group (Mean ± SD; 112.50 ± 5.80min versus 78.21 ± 9.12min;p < 0.001 and 237.14 ± 9.14min versus 215.00 ± 10.12min;p < 0.001, respectively). Time to requirement of first rescue analgesia was 184.29 ± 9.38min in the lidocaine group and 127.14 ± 23.35min in the control group (p < 0.001). VAS scores were lower in the lidocaine group at 4, 8, 12 and 24h after surgery (p < 0.00001, p < 0.00001, p < 0.00006, p = 0.032, respectively). Requirement of additional analgesia in the first 24h was higher in the control group. There were no clinical signs to suggest lidocaine toxicity in any patient. During unilateral TKR under spinal anaesthesia, concurrent use of intravenous lidocaine prolonged sensory block and reduced postoperative analgesic requirements.

Topical Therapies for Management of Olfactory Dysfunction in Chronic Rhinosinusitis with Nasal Polyps: Steroid-Eluting Stents.

Steroid-eluting stent implantation after endoscopic sinus surgery (ESS) effectively alleviates postoperative symptoms and polyp recurrence in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). However, the efficacy of steroid-eluting stents for the treatment of olfactory dysfunction in CRSwNP and the influencing factors therein have not been studied. Fifty-nine patients with CRSwNP with olfactory dysfunction from Peking University Third Hospital who were hospitalized for ESS were recruited and randomly divided into a stent group (n = 30) and a control group (n = 29), and were assessed for symptom scores, olfactory function, endoscopic findings, and type 2 inflammatory mediators (IL-4, IL-5, IL-13, IL-33, eotaxin-3, periostin) expression. Postoperative olfactory Visual Analogue Scale (VAS) scores, T&T olfactometer scores, SNOT-22 scores, and Lund-Kennedy (LK) scores were reduced in patients with CRSwNP (P < .01). Postoperative olfactory VAS scores, T&T olfactometer scores, SNOT-22 scores, and LK scores, IL-5, IL-13, and periostin were significantly lower in the stent group than in the control group (P < .05). Correlation analysis was performed and found that the postoperative olfactory VAS scores were strongly correlated with IL-5 and IL-13 (r = .496, P < .001 and r = .289, P = .026), and the postoperative T&T olfactometer scores were strongly correlated with IL-5 and IL-13 (r = .553, P < .001 and r = .398, P = .002). Steroid-eluting stent implantation after ESS is an effective treatment for olfactory deficits in patients with CRSwNP and may be related to the stent's more effective reduction of local type 2 inflammatory mediators in the nasal cavity.

Comparison of dynamic hip screw with anti-rotation screw and femoral neck system internal fixation for the treatment of garden II-IV type femoral neck fractures.

Femoral neck fractures, which are fractures occurring from the femoral head to the base of the femoral neck, are prevalent in the elderly population. With the progression of societal aging, the incidence of femoral neck fractures has been steadily increasing, making it a significant global issue that urgently needs to be addressed. To compare the efficacy and safety of dynamic hip screw (DHS) with anti-rotation screw and femoral neck system (FNS) internal fixation for the treatment of Garden II-IV type femoral neck fractures. A total of 90 patients with Garden II-IV type femoral neck fractures were randomly assigned to either the control group (n= 45) treated with DHS and anti-rotation screw or the experimental group (n= 45) treated with FNS. Surgical outcomes, including incision size, blood loss, operation time, fluoroscopy frequency, and fracture healing time, were compared. Postoperative complication rates, reoperation rates, Harris scores, and visual analogue scale (VAS) scores were also assessed. The experimental group demonstrated significantly reduced incision length, blood loss, operation time, and fluoroscopy frequency compared to the control group (P< 0.01). No significant differences were observed in fracture healing time, Garden classification, or fracture reduction outcomes between the two groups (P> 0.05). At 6 months post-treatment, both groups showed significant improvements in Harris scores and VAS scores compared to pre-treatment (P< 0.05), with no significant differences between the groups (P> 0.05). The rates of internal fixation failure, nonunion, and avascular necrosis of the femoral head, as well as overall incidence of postoperative complications and reoperation rates, showed no significant differences between the two groups (P> 0.05). Both DHS with anti-rotation screw and FNS internal fixation demonstrated comparable efficacy and safety profiles in the treatment of Garden II-IV type femoral neck fractures. The experimental group showed advantages in terms of reduced incision length, blood loss, operation time, and fluoroscopy frequency, while maintaining similar clinical outcomes and complication rates.

Comparison of low-pressure and standard-pressure pneumoperitoneum laparoscopic cholecystectomy in patients with cardiopulmonary comorbidities: a double blinded randomized clinical trial

BackgroundThe benefits of low-pressure laparoscopic cholecystectomy (LPLC) in patients with cardiopulmonary comorbidities remain unclear. This study aimed to explore the feasibility and pulmonary effects of LPLC in patients with cardiopulmonary comorbidities.MethodsThis was a multicenter, parallel, double-blind, randomized controlled trial. Eligible patients included patients with cardiac or pulmonary comorbidities, who were randomly assigned (1:1) to undergo LPLC (10 mmHg) or standard-pressure laparoscopic cholecystectomy (SPLC) (14 mmHg). The primary outcome was postoperative partial pressure of carbon dioxide (CO2). Surgical safety variables, patient recovery, pulmonary function parameters, and surgeon comfort were also compared between groups.ResultsThis study enrolled 144 participants, with 124 participants extracted for the final analysis (62 in LPLC and 62 in SPLC group, respectively). The median postoperative PaCO2 was similar in the LPLC (43.3 mmHg) and SPLC (43.0 mmHg) groups (p = 0.988). Pulmonary parameters including postoperative pH, PaCO2, HCO3, and lactate levels were similar between the two groups. Postoperative base excess was significantly higher in the LPLC group (− 0.6 mmol/L [− 6.9 ~ 7.5] vs. −1.9 mmol/L [− 6.6 ~ 5.4]; p = 0.031). There was no between-group difference regarding intraabdominal operative time, rate of intraoperative bile spillage, blood loss, surgeon comfort during surgery, and conversion rate. Moreover, postoperative major complication rates, the median time to the first flatus, postoperative hospital stay, or mean postoperative visual analog scale score for pain were similar in both groups.ConclusionsThis study found no reduction of partial pressure of CO2 with LPLC compared with SPLC for patients with cardiopulmonary comorbidities. LPLC with a pneumoperitoneum pressure of 10 mmHg may be safe and feasible for these patients when performed by experienced surgeons, although it does not improve pulmonary parameters.RegistrationThe trial is retrospectively registered at ClinicalTrials.gov (NCT04670952) on December 17, 2020.

Efficacy of endoscopic interlaminar decompression in lumbar spinal stenosis: a retrospective study.

This retrospective study evaluated the clinical effectiveness of endoscopic interlaminar decompression for lumbar spinal stenosis in 40 patients treated from February 2020 to January 2022. The procedure was successful in all cases, with only one dural sac injury reported and no other complications. Postoperative Visual Analogue Scale (VAS) and Japanese Orthopaedic Association (JOA) scores improved significantly (P<0.05), and the modified Macnab criteria showed an 87.5% rate of excellent and good outcomes at follow-up. No patients required revision surgery. Overall, the endoscopic interlaminar approach proved to be effective, safe, and supported early recovery.

Comparison of ultrasound-guided fascia iliaca compartment block versus the combined obturator nerve and adductor canal block application in postoperative analgesia for patients undergoing arthroscopic knee surgery

Background: Arthroscopic knee surgery is a surgical intervention that is frequently performed by orthopedic clinics and new studies are constantly carried out by anesthetists to ensure effective pain control. This study aimed to compare the efficacy of ultrasound-guided suprainguinal fascia iliaca compartment block (FICB) versus the combined adductor canal and obturator nerve block application in terms of postoperative analgesia in patients undergoing arthroscopic knee surgery under spinal anesthesia.Materials and Method: Sixty patients, who underwent arthroscopic knee surgery under elective conditions were included in the study. They were randomly divided into two groups, Group 1 (n=30) and Group 2 (n=30), using a lottery method. Patients operated under spinal anesthesia received ultrasound-guided suprainguinal fascia iliaca compartment block (FICB) for Group 1. The combined adductor canal and obturator nerve block for Group 2 at the end of the surgery. Intravenous patient-controlled analgesia (PCA) device containing tramadol was connected to all patients in both groups, and they were evaluated for Visual Analog Scale (VAS) scores at 0, 2, 4, 12, and 24 hours of ward follow-up. The amount of PCA used at 24 hours, additional analgesic use, development of side effects, mobilization capabilities, and satisfaction levels were assessed at the end of 24 hours.Results: There were no significant differences between the groups in terms of demographic characteristics and the type of surgery performed (p&gt;0.05). In Group 1, where fascia iliaca block was applied the block administration time was observed to be significantly shorter compared to Group 2 (p&lt;0.05). No significant differences were observed between the two groups in terms of postoperative VAS scores, PCA usage amounts, incidence of side effects, postoperative mobilization abilities, and satisfaction measures (p&gt;0.05).Conclusions: Ultrasound-guided fascia iliaca compartment block alone can be effectively applied for postoperative analgesia in patients undergoing arthroscopic knee surgery, instead of combined adductor canal and obturator nerve block.

Efficacy comparison of the S8 navigation-assisted correction versus manual correction in adolescent congenital scoliosis

Objective: Comparison of the efficacy of S8 navigation system-assisted correction versus manual correction in the treatment of adolescent congenital scoliosis (ACS). Methods: A cohort study. A retrospective analysis was conducted on the clinical and imaging data of 48 patients with congenital scoliosis who were treated at the Honghui Hospital Affiliated with Xi'an Jiaotong University between May 2021 and January 2023. Based on the auxiliary systems, the patients were divided into two groups: the S8 navigation system-assisted correction group (navigation group, n=20) and the C-arm-assisted manual correction group (manual group, n=28). The primary outcome measures were coronal balance (CB), sagittal vertical axis (SVA), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), pelvic incidence-lumbar lordosis mismatch (PI-LL), and the Scoliosis Research Society-22 (SRS-22) questionnaire. The secondary outcome measures included surgery-related conditions and postoperative complications. Results: Of the 48 patients, there were 21 males and 27 females, with a mean age of (13.3±3.0) years. There was no statistically significant differences in preoperative distance of C7 plumb line to center sacral vertical line (C7PL-CSVL), SVA, LL, PI, PT, PI-LL mismatch, or SRS-22 scores between the two groups (all P>0.05). Postoperatively, the C7PL-CSVL and SVA in the navigation group were both better than in the manual group [(12.51±11.86) mm vs (19.64±1.33) mm, (15.72±3.64) mm vs (25.42±2.53) mm, both P<0.05]. There was no statistically significant differences in postoperative LL, PI, PT, PI-LL mismatch, or SRS-22 scores between the two groups (all P>0.05). The accuracy rates for Grade 0 and Grade 0+1 screw placements were 91.17% (93/102) and 95.09% (97/102) in the navigation group, respectively, which were higher than those in the manual group [84.45% (125/148) and 91.89% (136/148), respectively] (both P<0.05). The rates of adjacent facet joint violation in Grades A, B, and C were 88.23% (90/102), 11.76% (12/102), and 0 (0/102) in the navigation group, respectively, which were all better than those in the manual group [83.44% (121/145), 8.96% (13/145), and 7.58% (11/145)] (P=0.015). The navigation group had shorter operative time, single screw placement time, and total screw placement time, and the distance between the screws and the cortex was closer compared to the manual group (all P<0.05). Intraoperative blood loss in the manual group was higher than that in the navigation group (P<0.05). The average curve correction rate in the navigation group (74.68%±10.70%) was better than that in the manual group (59.60%±6.90%) (P<0.001). The intraoperative fluoroscopy dose in the navigation group was higher than that in the manual group [(416±70) mGy vs (360±81) mGy, P=0.015]. The incision length in the navigation group was longer than that in the manual group (P<0.05). There was no statistically significant difference in preoperative VAS pain score between the two groups (P>0.05). The postoperative visual analogue scale scores of pain on day 3 was better in the navigation group [(2.60±0.22) vs (3.10±0.32), P<0.001], while there was no statistically significant differences at other time points between the two groups (all P>0.05). No complications occurred in either group. Conclusion: The S8 navigation system demonstrates good corrective outcomes, high screw placement accuracy, low facet joint violation, and favorable clinical results in the treatment of adolescent congenital scoliosis, making it an ideal auxiliary tool.

Comparative study on the effectiveness and safety of simultaneous and staged bilateral saphenous vein radiofrequency ablation

ObjectiveChronic venous insufficiency (CVI) is a common condition affecting more than one-half of the general population, with approximately 20% of cases being bilateral. The high prevalence, diagnosis, and treatment costs, along with the negative impact on patients' quality of life, underscore its significance. This study evaluates the clinical outcomes, quality-of-life effects, and postoperative complications of simultaneous and staged bilateral radiofrequency ablation (RFA) in patients with bilateral CVI in the great saphenous vein at Clinical, Etiological, Anatomical, Pathophysiological stages 2 to 4. MethodsThis retrospective study included 433 patients with bilateral CVI in the great saphenous vein at Clinical, Etiological, Anatomical, Pathophysiological stages 2 to 4, treated with RFA between January 2018 and December 2022. Patients were classified into two groups: group 1 (n = 257) underwent simultaneous bilateral RFA, and group 2 (n = 176) underwent staged bilateral RFA. Clinical outcomes and quality of life effects were evaluated using Venous Clinical Severity Score, Aberdeen Varicose Vein Questionnaire, and Visual Analog Scale scores. Demographic data, type of anesthesia, surgery durations, and postoperative complications were analyzed. ResultsBoth groups showed significant improvements in Aberdeen Varicose Vein Questionnaire and Venous Clinical Severity Score scores at 12 months postoperatively, with no significant differences between the groups in preoperative and postoperative scores. No significant difference was found in postoperative Visual Analog Scale scores. Postoperative complication rates were low and comparable. No pulmonary embolism was observed. Symptomatic deep vein thrombosis was detected in one patient from each group and treated successfully. ConclusionsSimultaneous bilateral RFA is as effective and safe as staged bilateral RFA for treating CVI, providing similar clinical outcomes and low complication rates. The simultaneous approach offers the advantage of a single treatment session, potentially improving patient satisfaction and operational efficiency. This study supports simultaneous bilateral RFA as a viable and effective option for treating bilateral CVI.

A Comparison of Clinical and Radiographic Outcomes Between Isolated Total Talus Replacement and Combined Total Talus Replacement with Total Ankle Arthroplasty or Hindfoot Arthrodesis

Total talus replacement (TTR) is a viable surgical option in the setting of talar avascular necrosis and collapse, as well as a revision option for failed total ankle arthroplasty with talar implant subsidence. The purpose of the present study was to compare the clinical and radiographic outcomes following isolated TTR and TTR combined with total ankle arthroplasty or hindfoot arthrodesis.Patients who underwent TTR were retrospectively reviewed, as a multicenter consecutive case series. Basic demographic data, comorbidities and surgical date were collected. Medical records were reviewed to obtain postoperative and preoperative visual analog scale (VAS) scores, American Orthopedic Foot and Ankle society (AOFAS) outcome scores, postoperative complications and radiographic measurements. Statistical analysis was conducted to compare radiographic and patient-reported outcomes pre- and postoperatively. Thirty-six patients underwent TTR with mean follow-up of 25.39 months.VAS pain scores improved postoperatively from 8.43 to 2.67 (P <0.001). AOFAS improved postoperatively from 36.33 to 81.78 (P < 0.001). There was an overall improvement in talar arc length (P = 0.035), talar width (P = 0.0037), talar height (P < 0.001), Bohler's (P < 0.001) and Gissane's angle (P = 0.004). The overall complication and subsequent surgery rate were each 16.7%. The TTR implant survivorship rate was found to be 94.5%. When comparing outcome scores between Isolated TTR and Combined TTR, no significant differences were detected in the degree of improvement.Both isolated and combined TTR provide a suitable and safe option for the treatment of advanced talar AVN or associated tibiotalar and hindfoot arthritis.

C1 root decompression as a therapeutic target in non-suboccipital non-Valsalva related headache associated with Chiari I malformation

Headache is the most common symptom impacting the quality of life of patients with Chiari I malformation. While headaches typically present in the occipital or suboccipital regions, and induced by Valsalva maneuver, complex migraine-like headaches referring to frontal or orbital regions also occur. Our study explores the therapeutic potential of C1 nerve root decompression in addition to increasing intracranial compliance in patients with Chiari I malformation. We retrospectively analyzed cases operated on for Chiari I malformation, focusing on patients with non-suboccipital, non-Valsalva induced headaches. Preoperative and postoperative visual analog scale (VAS) scores and headache frequency were recorded. Surgical technique involved suboccipital craniectomy, C1 laminectomy, cerebellar tonsil reduction, and C1 root decompression. Twelve patients (10 females, 2 males) aged 22-52 were included. Preoperative mean VAS score was 8, which improved to 2 or less in 11 patients postoperatively. The mean headache frequency decreased significantly. Our findings suggest that C1 root compression contributes to atypical headaches in Chiari I malformation and that C1 root decompression may improve surgical outcomes.

Risk Factors for Early Subsidence of 3D-Printed Artificial Vertebral After Anterior Cervical Corpectomy and Fusion

ObjectiveThe subsidence of vertebral body replacement may occur after anterior cervical corpectomy and fusion (ACCF) , which may lead to cervical kyphosis, spinal cord compression and neurological dysfunction. The authors aim to investigate the risk factors for early subsidence of 3D printed artificial vertebral (3D-PAVB) after ACCF surgery and to provide guidance for clinical practice. MethodsA retrospective analysis was conducted on the data of consecutive patients with cervical spondylosis who underwent ACCF surgery at Bethune Hospital of Shanxi from 2017 to 2020. The statistical data included age, gender, disease type, body mass index (BMI), surgical segment, vertebral height, Cobb Angle, and Hounsfeld Units (HU) values of the vertebral body and endplate. The clinical efficacy of the surgery was evaluated using Visual Analog Scale (VAS), Japanese Orthopedic Association (JOA), and Neck Disability Index (NDI). Follow-up data, such as VAS, JOA, NDI, and Cobb Angle, were obtained using a repeated-measures ANOVA analysis. Univariate analysis was conducted to identify the factors contributing to the early subsidence of the3D-PAVB, and independent risk factors were determined using logistic regression. The HU value was analyzed using the Receiver Operating Characteristic (ROC) curve and the area under the Area Under Curve (AUC) to predict the subsidence of the 3D-PAVB. ResultsA total of 66 patients were included in the study, out of which 19 patients experienced subsidence of 3D-PAVB,resulting in an incidence rate of 28.8%. The postoperative JOA, VAS, and NDI scores showed significant improvement in both the subsidence and non-subsidence groups. Upon conducting univariate analysis, significant differences were observed between the two groups in terms of age, diabetes, smoking, and lower vertebral Computed Tomography (CT) values. The average HU value of the subsidence group (251.39±52.615, n=19) was significantly lower than that of the non-subsidence group (317.06±73.587, n=47, p＜0.01). Multivariate analysis revealed that smoking and HU of the lower vertebra were independent risk factors for 3D-PAVB subsidence, with an AUC of 0.772 and an optimal threshold of 272 for HU (sensitivity 78.9%, specificity 74.5%). ConclusionThe occurrence of early subsidence of 3D-PAVB post ACCF surgery is influenced by two independent risk factors - smoking and low HU. To predict the likelihood of this outcome, it is advisable to consider smoking history and measure CT HU value prior to surgery. A lower CT HU value is indicative of a greater risk of subsidence.

Three-dimensional-printed guide plate for direct percutaneous pedicle screw implantation in minimally invasive transforaminal lumbar interbody fusion surgery: a retrospective study of 162 patients

BackgroundThis study aimed to investigate the impact of three-dimensional (3D)-printed guide plate-assisted percutaneous pedicle screw implantation on minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) surgery.MethodsOverall, 162 patients who underwent MIS-TLIF at Tai’an City Central Hospital were retrospectively reviewed. The studied variables included operative time, volume of intraoperative blood loss, fluoroscopy time, postoperative drainage volume, visual analogue scale (VAS) score, Oswestry disability Index (ODI) score (preoperatively and at 2 weeks, 3 months, 6 months, and 12 months after surgery), and intervertebral fusion rate at 6 months after surgery.ResultsThe conventional group included 99 patients who underwent a conventional procedure, while the 3D printing group included 63 patients who underwent 3D-printed guide plate-assisted percutaneous pedicle screw implantation. The conventional group required more times of positioning needle punctures than the 3D printing group (22.2 ± 5.9 vs. 16.1 ± 4.9). The operation and fluoroscopy time were also longer in the former group (183.5 ± 51.1 min vs. 148.8 ± 40.3 min and 30.2 ± 5.9 s vs. 24.1 ± 4.9 s, respectively). In 3D printing group, lower back pain VAS scores and ODI scores at 2 weeks and 3 months after surgery were observed. There were no significant differences in terms of the volumes of intraoperative blood loss; postoperative lower limb pain VAS scores; and interbody fusion rate (P > 0.05).ConclusionThe novel 3D-printed guide plate-assisted percutaneous pedicle screw implantation can achieve better amelioration of back pain and recovery of function. It also reduced the times of positioning needle puncture and fluoroscopy time during percutaneous screw placement surgery and reduced the duration of surgery.

The analgesic benefit of rectus sheath block in robotic gynecologic surgery: A retrospective study.

With the growing adoption of robotic techniques in gynecologic surgery, the advantages of minimally invasive procedures over traditional open surgery, such as reduced postoperative pain and quicker recovery, are clear. Yet, establishing an effective multimodal analgesic regimen remains a challenge. This retrospective study from a tertiary care center aimed to assess the analgesic efficacy of the rectus sheath block (RSB) on postoperative pain and opioid consumption after robotic gynecologic surgery. Between June 2022 and March 2023, 20 patients who underwent robotic gynecologic surgery were evaluated. Key parameters included postoperative visual analog scale scores, opioid consumption, and postoperative nausea/vomiting instances. Anesthesia protocols were standardized, with postsurgical pain management involving RSB and a patient-controlled analgesia device filled with morphine. Patients showed an average morphine intake of 8.2 ± 5.09 mg over the initial 24 hours postsurgery. During mobilization, average pain scores were consistently low, with no correlation identified between opioid consumption and age or body mass index. 40% of patients reported postoperative nausea on the first day, and no complications linked to the RSB were observed. The study underlines the potential of integrating RSB in a multimodal analgesic regimen after robotic gynecologic surgery. Its application may lead to reduced opioid consumption and more efficient postoperative pain management. Further randomized controlled trials are recommended to validate these findings.

Comparative efficacy of unilateral biportal endoscopic and full-endoscopic posterior cervical foraminotomy in the treatment of cervical spondylotic radiculopathy: a retrospective analysis.

The aim of this study was to compare the clinical efficacy of the full-endoscopic posterior cervical foraminotomy (FE-PCF) and the unilateral biportal endoscopic posterior cervical foraminotomy (UBE-PCF) in the treatment of cervical spondylotic radiculopathy (CSR). Patients who underwent posterior cervical spine surgery in our hospital from January 2020 to December 2022 were retrospectively analyzed. According to the surgical method, the patients were divided into two groups: FE-PCF group and UBE-PCF group. Perioperative data included operation time, Intraoperative blood loss and postoperative hospital stay were collected. The Visual Analog Scale (VAS)-arm, VAS-neck, and Neck Diability Index (NDI) was used to evaluate the clinical outcomes at preoperative, postoperative 1 week and Last follow-up. Serum creatine phosphokinase (CPK) and C-reactive protein (CRP) levels were recorded to evaluate surgical invasiveness. A total of 160 patients were included, including 89 cases of FE-PCF and 71 cases of UBE-PCF. The demographic and preoperative data showed no significant differences between the two groups (P > 0.05). The mean operating time was significantly shorter in the UBE-PCF group compared to FE-PCF group (P < 0.05). Serum CRP and CPK levels of the two groups both exhibited a pattern of rising and then falling, peaking one day following surgery and decreasing to near normal values three days after the operation. Compared with preoperative, both groups showed significant improvement in postoperative VAS and NDI scores, with a statistically significant difference (P < 0.05). However, the differences in results between the groups were not significant. Both UBE-PCF and FE-PCF are secure and efficient methods for treating CSR by continuous visualization. UBE-PCF offers predictable and adequate decompression within a reduced surgical duration, facilitated by its separate observation and operation channels.

A More Efficient and Safer Improved Percutaneous Pedicle Screw Insertion Technique-Trajectory DynamicAdjustment Technique, Technical Note, and Clinical Efficacy.

Percutaneous pedicle screw fixation (PPSF) technique requires a very precise entry point of the Jamshidi needle, which leads to repeated adjustments, damaging the pedicle and increasing radiation exposure. This study was designed to propose an improved percutaneous pedicle screw fixation technique-trajectory dynamic adjustment (TDA) technique, and evaluate its feasibility and assess the clinical outcomes. A total of 445 patients with lumbar spondylolisthesis or lumbar spinal stenosis associated with instability from June 2017 to May 2022 were included in the retrospective study. They were randomly separated into two groups. Two hundred thirty-one patients underwent TDA technique (TDA group). Two hundred fourteen patients underwent traditional PPSF technique (PPSF group). All patients underwent postoperative CT to assess the accuracy of screw placement, superior facet joint violation (FJV). The evaluated clinical outcomes were needle insertion time, radiation exposure, blood loss, hospital stay, the Japanese Orthopedic Association (JOA) score, the Visual Analogue Scale (VAS) scores for lower back pain (LBP), and leg pain, lumbar interbody fusion rate, and postoperative complications. The independent-sample t test and paired t-test were used for continuous data. The contingency table and Mann-Whitney U test were used for categorical data. The time of the insertion in TDA group was significantly lower than that in PPSF group (p < 0.05). Similarly, the fluoroscopy frequency in TDA group was significantly lower than that in PPSF group (p < 0.05). There was no difference in intraoperative blood loss and hospital stay between the two groups (p > 0.05). Overall, there was no significant difference in the proportion of clinically acceptable screws between the two groups (p > 0.05). In addition, the lateral screw misplacement in TDA group was higher. Moreover, FJV rate was significantly lower than that in PPSF group (p < 0.05). In both TDA group and PPSF group, postoperative back and leg pain and the JOA score were significantly improved (p < 0.05). However, there were no significant differences in the pre- and postoperative VAS score for back and leg pain and the JOA score, JOA recovery rate, intervertebral fusion rate, and complications rate between the two groups (p > 0.05). Compared to traditional PPSF technique, TDA technique is a safer and more effective procedure which has shorter surgical time, lower radiation exposure, and lower facet joint violation rate.
