BACKGROUND
Lumbar degenerative conditions are a major cause of back pain and disability in individuals aged 45 and above. Gait analysis utilizes sensor technology to collect movement data, aiding in the evaluation of various gait aspects like spatiotemporal parameters, joint angles, neuromuscular activity, and joint forces. It is widely used in conditions such as cerebral palsy and knee osteoarthritis. This research aims to assess the effectiveness of 3D gait analysis in evaluating surgical outcomes and postoperative rehabilitation for lumbar degenerative disorders.
METHODS
A prospective self-controlled before-after study (n = 85) carried out at our Hospital (Sep 2018 - Dec 2021) utilized a 3D motion analysis system to analyze gait in patients with lumbar degenerative diseases. The study focused on the multifidus muscle, a crucial spinal muscle, during a minimally invasive lumbar interbody fusion surgery conducted by Shandong Weigao Pharmaceutical Co., Ltd. Pre- and postoperative assessments included time-distance parameters (gait speed, stride frequency, stride length, stance phase), hip flexion angle, and stride angle. Changes in 3D gait parameters post-surgery and during rehabilitation were examined. Pearson correlation coefficient was employed to assess relationships with the visual analog pain scale (VAS), Oswestry Disability Index (ODI), and Japanese Orthopedic Association (JOA) scores. Patient sagittal alignment was evaluated using "Surgimap" software from two types of lateral radiographs to obtain parameters like pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), intervertebral space height (DH), posterior height of the intervertebral space (PDH) at the operative segment, and anterior height of the intervertebral space (ADH).
RESULTS
By the 6th week post-operation, significant improvements were observed in the VAS score, JOA score, and ODI score of the patients compared to preoperative values (P < 0.05), along with notable enhancements in 3D gait quantification parameters (P < 0.05). Pearson correlation analysis revealed a significant positive correlation between improvements in 3D gait quantification parameters and VAS score, JOA score, and ODI value (all P < 0.001).
CONCLUSION
3D gait analysis is a valuable tool for evaluating the efficacy of surgery and rehabilitation training in patients.

OBJECTIVE
Autologous iliac bone is commonly used as a bone graft material to achieve solid fusion in craniocervical junction (CVJ) surgery. However, the developing iliac bone of children is less than ideal as a bone graft material. The matured rib bone of children presents a potential substitute material for iliac bone. The aim of this study was to evaluate the efficacy of autologous rib grafts for craniocervical junction surgery in children.
METHODS
The outcomes of 10 children with abnormalities of the craniocervical junction who underwent craniocervical junction surgery between January 2020 and December 2022 were retrospectively reviewed. All patients underwent posterior fusion and internal fixation surgery with autologous rib grafts. Pre- and post-operative images were obtained and clinical follow-ups were conducted to evaluate neurological function, pain level, donor site complications, and bone fusion rates.
RESULTS
All surgeries were successful. During the 8- to 24-month follow-up period, all patients achieved satisfactory clinical results. Computed tomography at 3-6 months confirmed successful bone fusion and regeneration of the rib defect in all patients with no neurological or donor site complications.
CONCLUSION
Autologous rib bone is a safe and effective material for bone grafting in craniocervical junction fusion surgery for children that can reduce the risks of donor site complications and increase the amount of bone graft, thereby achieving a higher bone fusion rate.

BACKGROUND This retrospective study included 31 patients from 2 centers in Türkiye with posttraumatic ankle osteoarthritis treated with anterior tibiotalar arthrodesis using an anterior plate and cannulated screw fixation, with 6 months of follow-up. MATERIAL AND METHODS In this bi-center study, conducted between January 2018 and July 2022, we retrospectively reviewed the digital records of 31 patients with end-stage posttraumatic ankle osteoarthritis who were treated with anterior tibiotalar arthrodesis surgery using 2 or 3 cannulated screws and the anterior plating technique. Data on age, gender, comorbidities, and smoking were recorded, as were operative technique and graft use. Union characteristics, complications, visual analog scale (VAS) results, and Maryland functional scoring were assessed preoperatively and at the 6-month follow-up visit. RESULTS The mean age of the 31 (n=13 male, n=18 female) patients was 55.5 (19-82) years. The union findings were good in 26 (83.9%) of the patients and late in 3 (9.7%) of them. Nonunion was seen in 2 (6.5%) patients. Complications were observed in 7 (22.6%) patients. Union formation was statistically significantly prolonged among the cases with complications (P=0.002). The smoking rate was significantly higher in patients encountering complications (P=0.001). Among cases with complications, the VAS and Maryland scores recorded in the postoperative sixth month were significantly higher (P=0.027, P=0.018, respectively). The mean union time was 13.5±6.5 weeks among all of the patients. CONCLUSIONS Our study showed that cannulated screw fixation, strengthened with the common and easy-to-supply anterior reconstruction plating technique, had high fixation power and good functional results in patients with end-stage posttraumatic ankle osteoarthritis.

Comparative Study
Outcome after total ankle replacement or ankle arthrodesis in end-stage ankle osteoarthritis on the basis of german-wide data: a retrospective comparative study over 10 years.
BACKGROUND
In symptomatic end-stage osteoarthritis of the ankle joint, total ankle replacement and ankle arthrodesis are the two primary surgical options for patients for whom conservative treatment fails. Published revision rates are often biased and difficult to compare. In this study, unplanned reoperation rates and revision rates were determined for both surgical interventions based on a large dataset, and risk factors for unplanned reoperations were identified.
METHODS
German-wide health data of the largest German health-care insurance carrier between 2001 and 2012 were retrospectively analyzed, and unplanned reoperation rates within 10 years were determined for index surgeries conducted in 2001 and 2002. Unplanned reoperation rates within 5 years for index surgeries conducted in 2001/2002 were compared to index surgeries conducted in 2006/2007. Multivariate logistic regression was used to identify risk factors for unplanned reoperations.
RESULTS
After ankle arthrodesis, 19% (95% confidence interval [CI], 16-22%) of 741 patients needed to undergo an unplanned reoperation within ten years. After total ankle replacement, the unplanned reoperation rate was 38% [95% CI, 29-48%] among 172 patients. For initial surgeries conducted at a later date, unplanned reoperation rates within five years were 21% [95% CI, 19-24%] for 1,168 ankle arthrodesis patients and 23% [95% CI, 19-28%] for 561 total ankle replacement patients. Significant risk factors for unplanned reoperations after ankle arthrodesis in the initial cohort were age < 50 years (odds ratio [OR] = 4.65 [95% CI 1.10;19.56]) and osteoporosis (OR = 3.72 [95% CI, 1.06;13.11]); after total ankle replacement, they were osteoporosis (OR = 2.96 [95% CI, 1.65;5.31]), Patient Clinical Complexity Level (PCCL) grade 3 (OR = 2.19 [95% CI, 1.19;4.03]), PCCL grade 4 (OR = 2.51 [95% CI, 1.22;5.17]) and diabetes mellitus (OR = 2.48 [95% CI, 1.33;4.66]). Kaplan-Meier analyses including 1,525 ankle arthrodesis patients and 644 total ankle replacement patients revealed an average unplanned reoperation-free time of approximately 17 years for both procedures.
CONCLUSIONS
Similar revision rates and unplanned reoperation rates for both procedures in the later-date cohort can likely be attributed to a learning curve for surgeons as well as advances in implant design. This analysis of billing health insurance data supports an increase in total ankle replacement surgeries.

While the Lapidus bunionectomy is a common procedure utilized to address hallux valgus, the incidence of secondary surgery is not well established. Our primary goal was to determine the incidence of revision surgery and hardware removal following the Lapidus bunionectomy in addition to the risk factors associated with each. A retrospective nested case-control study of adult patients who underwent a Lapidus bunionectomy for symptomatic hallux valgus over a nine-year period was performed. The incidence rates and 95% confidence intervals (CI) of secondary surgery in the three years following the procedure along with the estimated independent associations and odds ratios between baseline demographic, clinical, and radiographic characteristics were calculated. Of the original cohort of 2,540 patients, 127 were identified (5.0%; CI: 4.1%, 5.8%) who underwent revision surgery and 165 (6.5%; CI: 5.5%, 7.5%) who underwent hardware removal following Lapidus bunionectomy. Initially, the hallux valgus angle, intermetatarsal angle, and tibial sesamoid position were risk factors for revision surgery. However, in adjusted analyses for revision surgery, using a screw for third point of fixation emerged as the only independent risk factor (odds ratio [OR]=3.01; CI: 1.59, 5.69). In adjusted analyses for hardware removal, female sex (OR=2.33; CI: 1.08, 5.00) and third point of fixation (OR=2.92; CI: 1.82, 4.69) emerged as independent risk factors. While the overall risks associated with Lapidus bunionectomy are low and the need for revision surgery are low, this study helps to identify specific risk factors for secondary surgery and hardware removal to help in evaluation and discussion with patients.

CASE
A 64-year-old man presented with a 3-year history of right wrist pain and swelling 33 years after a silicone scaphoid arthroplasty for chronic scaphoid nonunion. Radiographs demonstrated a deformed scaphoid implant, carpal and distal radius cysts, and mild carpal collapse. He elected to undergo a wrist arthrodesis with a dorsal fusion plate after failing conservative management.
CONCLUSION
Although carpal bone silicone implant arthroplasties of the wrist have long been abandoned, our patient was pain free and fully functional for 3 decades. He was pleased to undergo serial examinations with radiographs for 30 years without any therapeutic intervention.

Salvage revisions of atlantoaxial (AA) joint complex posterior segmental instrumented fusion constructs require careful individualized planning to prevent occipital extension. In this case report, we describe the use of bilateral intrafacet spacer placement as a mobility-sparing bailout option for the revision surgery. A 64-year-old male with a history of diffuse idiopathic skeletal hyperostosis, extremely limited baseline cervical mobility, and prior AA posterior segmental instrumented fusion presented with increasing pain at his 6-month follow-up. Imaging showed fusion and hardware failures and dynamic instability. To prevent occipitocervical fixation, AA intra-articular fusion via a DTRAX spinal system (Providence Medical Technology, Inc) was used as an adjunct to a navigated C1 lateral mass and C2 pars screw posterior segmental instrumented fusion construct. The patient had an uneventful postoperative course and was discharged with resolution of symptoms. Three-month postoperative follow-up confirmed persistent resolution of symptoms and absence of complaints, along with successful arthrodesis on imaging. AA posterior segmental instrumented fusion revision is technically challenging, particularly when partial preservation of craniovertebral junction mobility is required. Bilateral intra-articular cages may be used as an adjunct to hardware revision in construct salvage when sturdy arthrodesis is desired without occipital extension and may represent a major potential strength of intra-articular cages.

INTRODUCTION
Fixed Equinus deformity is characterized by limited dorsiflexion of ankle joint and restricted passive movement, along with medial and lateral tibiotalar instability, progressive hindfoot varus, and a supination deformity of the forefoot. Degree of equinus deformity is determined by the Tibio-Metatarsal (TM) angle, subtended between the longitudinal axes of Tibia and 1st Metatarsal, in lateral view of foot. Lambrinudi triple arthrodesis involves the surgical fusion of the talonavicular, talocalcaneal, and calcaneocuboid joints to correct fixed foot deformities, to relieve pain from joint, to provide stability to the imbalanced foot, and to create a plantigrade foot. We combined a Lambrinudi type arthrodesis with a transfer of the posterior tibial tendon (PTT) in adult patients to provide dynamic dorsiflexion and pronation.
CASE REPORT
The case was of 39-year-old male diagnosed as fixed cavoequinus deformity of right foot and ankle, who was operated with Lambrinudi triple arthrodesis with PTT transfer in January 2019 and followed up to 5 years. Outcome measurements included radiographic and clinical investigations, including the TM Angle, American Orthopaedic Foot and Ankle Society (AOFAS) Score and Ankle range of motion (ROM), which were assessed preoperatively, immediate postoperatively, at 3 months, 6 months, 1 year, and 5 years.The TM angles were 177, 133, 125, and 122, at pre-operative, immediate post-operative, 3 months, 5 years, respectively. Fusion was seen at 1-year follow-up. Improvement in AOFAS Score with values 38, 57, 73, and improvement in Ankle ROM with values 0 (fixed), 10, 15° at pre-operative, 3 months, and 5 years postoperative, respectively. Patient could use ordinary footwear afterward and had no significant subjective pain or pain which affected his daily activities, but patient had post-procedural right lower limb shortening of 1 cm..
CONCLUSION
This combined procedure demonstrated clinical correction of foot deformity and significant improvement in functional outcome in the form of AOFAS score and Ankle ROM. The ability of all patients to use normal shoes and significant reduction in pain scores represent ultimately, the improvement in quality of life. We have corrected muscle imbalance and provided dynamic force for dorsiflexion and pronation of foot in the form of tibialis posterior.

BACKGROUND
posterior pedicle screw fixation is common method, one of the most severe complications is iatrogenic vascular damage, no report investigated association of different introversion angles (INTAs) and length of pedicle screw. The aims were to investigate the optimal introversion angle and length of pedicle screw for improving the safety of the operation, and to analyze the differences of vascular damage types at L1-S1.
METHODS
Lumbar CT imaging data from110 patients were analyzed by DICOM software, and all parameters were measured by new Cartesian coordinate system, INTAs (L1-L5:5°,10°,15°,S1: 0°, 5°,10°,15°), D (the distance between the origin (O) with anterior vertebral cortex (AVC)), D (the distance between AVC and the prevertebral great vessels (PGVs)), D (the distance between the O and PGVs). At different INTAs, D were divided into four grades: Grade III: D ≤ 3 mm, Grade II: 3 mm < D ≤ 5 mm, Grade I: D > 5 mm, and N: the not touching PGVs.
RESULTS
The optimal INTA was 5° at L1-L3, the left was 5° and the right was 15° at L4, and screw length was less than 50 mm at L1-L4. At L5, the left optimal INTA was 5° and the right was 10°, and screw length was less than 45 mm. The optimal INTA was 15° at S1, and screw length was less than 50 mm. However, screw length was less than 40 mm when the INTA was 0° or 5° at S1.
CONCLUSIONS
At L5-S1, the risk of vascular injury is the highest. INTA and length of the pedicle screw in lumbar operation are closely related. 3 mm interval of screw length may be more preferable to reduce vascular damage.
