Orthopedic Trauma: Surgical Treatment and Rehabilitation

Background and Objectives: Long spinal fusion terminating at L5 remains controversial because of the risk of postoperative junctional failure. Although degeneration of the residual L5–S1 disc has been suggested as a contributing factor, the relative impact of disc degeneration versus sagittal spinopelvic alignment on different junctional failure patterns has not been fully clarified. Materials and Methods: This retrospective cohort study included 47 patients aged ≥60 years who underwent ≥5-level thoracolumbar fusion ending at L5 with a minimum follow-up of 2 years. Junctional failures were classified as proximal junctional failure (PJF) or distal junctional failure (DJF). Preoperative L5–S1 disc degeneration was assessed using modified Weiner and Pfirrmann classifications. Spinopelvic parameters were measured preoperatively, postoperatively, and at final follow-up. Junctional failure–free survival was analyzed using the Kaplan–Meier method, and risk factors were explored using Cox proportional hazards models. Results: Junctional failures occurred in 28 patients (59.6%), including 16 PJFs (34.0%) and 10 DJFs (21.3%). Lower grades of L5–S1 disc degeneration (Weiner grades 0–1) were more frequently associated with PJFs, whereas higher grades (≥2) were predominantly associated with DJFs (p = 0.024). Multivariate analysis showed that preoperative thoracolumbar kyphosis (hazard ratio [HR] = 1.164), preoperative T1 pelvic angle (HR = 1.269), and postoperative pelvic incidence–lumbar lordosis mismatch (HR = 0.877) as significant risk factors for PJF. Postoperative proximal junctional angle (HR = 0.899) and lumbar lordosis (HR = 0.920) were independently associated with DJF. Conclusions: Sagittal spinopelvic alignment parameters appear to have a greater influence on junctional failure patterns than residual L5–S1 disc degeneration in long fusions terminating at L5. Adequate sagittal correction should be prioritized to reduce the risk of both proximal and distal junctional failures. Full article

Background and Objectives: The aim of this study was to compare the clinical and radiological outcomes of the nail-plate combination (NPC) and double-plate (DP) fixation techniques in revision surgery performed after fixation failure of periprosthetic distal femur fractures. Materials and Methods: Patients who underwent revision surgery for periprosthetic distal femur fractures following fixation failure between 2018 and 2023 at a tertiary referral center were retrospectively reviewed. Based on the surgical technique, patients were divided into two groups: NPC group (n = 27) and DP group (n = 45). Demographic characteristics, operative time, intraoperative blood loss, and fluoroscopy time were recorded. Radiological evaluation included union time, while clinical outcomes were assessed with the Knee Society Score (KSS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the Short Form-36 (SF-36) health survey. Complications (infection, thromboembolism, implant failure, nonunion, malalignment), reoperation, and 1-year mortality rates were also analyzed. Results: The NPC group had significantly shorter operative time (107 vs. 134 min, p < 0.001) and lower intraoperative blood loss (412 vs. 634 mL, p < 0.001). Hospital stay was shorter in the NPC group (6.9 ± 1.5 vs. 10.2 ± 3.3 days, p < 0.001). Mean union time was approximately three weeks shorter in the NPC group (15.4 vs. 18.8 weeks, p < 0.001). Functional outcomes (KSS, WOMAC, SF-36) did not differ significantly between groups. Complication rates were comparable; implant failure was the most frequent complication (NPC: 3.7% vs. DP: 13.3%). One-year mortality did not differ significantly (NPC: 7.4% vs. DP: 11.1%). Conclusions: Compared with DP fixation, the NPC technique offers clear perioperative advantages in revision surgery performed after fixation failure of periprosthetic distal femur fractures, including shorter operative time, reduced blood loss, and faster union. Functional outcomes and complication rates were similar between techniques. These findings suggest that the NPC may represent a safer and more feasible alternative. Full article

Background and Objectives: Coracoid process (CP) fractures combined with acromioclavicular (AC) joint dislocation are extremely rare, and evidence guiding optimal surgical management remains limited. This retrospective, single-center case series study evaluated clinical and radiologic outcomes after simultaneous fixation of both lesions using a clavicular hook plate and a coracoid screw. Materials and Methods: We retrospectively reviewed 15 consecutive patients with Ogawa type I CP fractures combined with AC joint dislocation who underwent clavicular hook plate and coracoid screw fixation between March 2019 and May 2024. Clinical outcomes at final follow-up included shoulder range of motion (ROM), visual analog scale (VAS) for pain, and the Constant score. Radiologic outcomes included CP union confirmed by computed tomography (CT) and residual AC joint subluxation. Results: The cohort comprised 13 men and 2 women with a mean age of 55.2 years, and the mean final follow-up was 40.2 months. At final follow-up, mean ROM was 168° for forward elevation, 161° for abduction, and 69° for external rotation at the side, with internal rotation to L1. The mean VAS score was 0.4 and the mean Constant score was 97. CT-confirmed union of the CP fracture was achieved in all patients, and no residual AC joint subluxation was observed. All patients returned to sports and activities of daily living. Conclusions: In this series, simultaneous fixation using a clavicular hook plate and a coracoid screw provided reliable stabilization for CP fractures with AC joint dislocation, achieving consistent CP union, restoration of AC joint alignment, and favorable clinical outcomes. However, given the retrospective, non-comparative study design, these findings should be interpreted with caution, and further comparative studies are warranted. Full article

Background and Objectives: Unstable distal clavicle fractures (Neer type II) have a relatively high risk of nonunion and often require operative fixation. Hook plates are widely used, particularly when the distal fragment is small or comminuted, because they provide strong vertical stability. However, hook plates are associated with subacromial irritation, acromial wear, and the need for routine implant removal. Distal locking plates with supplementary cerclage augmentation can achieve fixation without subacromial impingement and may reduce implant-related complications. This study aimed to compare clinical and radiologic outcomes of hook plates versus locking plates with or without cerclage augmentation for Neer type II distal clavicle fractures. Materials and Methods: In this single-center retrospective cohort, adult patients with Neer type II distal clavicle fractures who underwent open reduction and internal fixation between March 2021 and August 2022, with ≥6 months of follow-up, were reviewed. Patients were allocated into two groups according to implant: hook plate (Group 1, n = 16) and distal locking plate with or without cerclage augmentation (Group 2, n = 26). Primary outcomes were complication rate, radiographic union, and shoulder range of motion (ROM). Secondary outcomes included pain (PVAS) and functional scores (SANE, ASES, Constant, UCLA). Results: Forty-two patients were analyzed (locking n = 26, hook n = 16). Groups were comparable in age (51.3 ± 16.0 vs. 54.4 ± 17.1 years), follow-up (7.0 ± 4.0 vs. 8.4 ± 4.3 months), sex distribution, smoking status, and mechanism of injury. Radiographic union was achieved in 24/26 (92.3%) patients in the locking group and 14/16 (87.5%) in the hook group; two cases of nonunion or reduction failure occurred in each group (p = 0.612). Final patient-reported outcomes and ROM were similar between groups (e.g., ASES 68.2 ± 15.5 vs. 64.4 ± 18.3, Constant 57.3 ± 9.5 vs. 44.9 ± 20.5; all p > 0.05). Forward flexion tended to be higher in the locking group (138.9 ± 28.0° vs. 113.3 ± 36.7°, p = 0.182), although without statistical significance. No deep infection, peri-implant fracture, or hardware failure requiring unplanned revision was observed. Subacromial wear was identified in four patients (25%) in the hook plate group, whereas no such change was observed in the locking group. Conclusions: Both hook plates and distal locking plates (±cerclage) provided high union rates and satisfactory functional outcomes for Neer type II distal clavicle fractures. However, hook plates were associated with subacromial wear, whereas locking plate constructs avoided subacromial complications. When distal fragment purchase is feasible—or can be supplemented with cerclage augmentation—locking plate fixation represents a reliable first-line option, with hook plates reserved for cases with minimal distal bone stock or complex comminution.

Background and Objectives: Hook plate fixation has been widely used for unstable distal clavicle fractures, but concerns remain regarding implant-related complications and the need for secondary removal. Locking plate fixation with supplementary cerclage wiring has been proposed as an alternative that may provide stability while reducing complications. This study compared the clinical and radiologic outcomes of locking plate fixation with cerclage wiring versus hook plate fixation. Materials and Methods: A retrospective review was performed on patients who underwent open reduction and internal fixation for unstable distal clavicle fractures (Cho’s classification type II) between 2015 and 2024. Patients with at least 6 months of follow-up were included. Two techniques were evaluated: locking plate with cerclage wiring (Group 1) and hook plate fixation (Group 2). Clinical outcomes, including complications, range of motion, and patient satisfaction, were compared at the final follow-up. Results: A total of 52 patients met the inclusion criteria: 27 in Group 1 and 25 in Group 2. The overall mean follow-up period was 13.17 ± 8.46 months. The distribution of fracture types was not significantly different between groups (p = 0.287). Complications were more frequent in Group 2 (40%), including postoperative stiffness requiring capsular release (70%), nonunion requiring revision (20%), and peri-implant fracture (10%). The overall union rate was 100% in Group 1 and 80% in Group 2. In contrast, Group 1 had only one complication (3.7%), a peri-implant fracture (p = 0.002). Shoulder range of motion at the final follow-up showed no significant difference between groups. Conclusions: Hook plate fixation was associated with a significantly higher complication rate compared with locking plate fixation with cerclage wiring. Locking plate fixation with supplementary cerclage wiring appears to be a better surgical option for unstable distal clavicle fractures. Full article

Background and Objectives: Our study aimed to retrospectively examine the routine radiographs on the first postoperative day of osteosynthesis applications performed in the supine position with the help of a traction table, in the lateral decubitus position, and in the supine position in patients with intertrochanteric fractures of the femur who had a proximal femoral nail applied. It also aimed to compare them in terms of radiology. This study investigated the effects of three different patient positions on fracture reduction, a topic rarely encountered in the literature. Materials and Methods: Patients who underwent proximal femoral nailing in three different positions—the supine, traction table, and lateral decubitus positions—due to femoral intertrochanteric fractures in two different centers were analyzed. A total of 157 patients with complete early radiographs were included in this study to evaluate the quality of postoperative reduction and fixation. Results: There was a significant difference between the traction table-assisted supine position group (mean: 25.31 mm) and both the lateral decubitus position (mean: 31.91 mm) and supine position (mean: 31.79 mm) groups in terms of the TAD (p = 0.000). Regarding the collodiaphyseal angle, the traction table-assisted supine position (mean: 130.720°) and lateral decubitus position (mean: 130.290°) groups showed significantly higher values than the supine position group (mean: 124.190°) (p = 0.000). The average lengths of the lag and compression screws were lower in the lateral decubitus position group compared with the other groups (p = 0.000). Patients in the supine position group had smaller nail diameters and lengths (p = 0.000). When examining the Cleveland–Bosworth lag screw placements, the most frequent position was center–center, including 22 patients (31%) in the traction table-assisted supine position group, 15 patients (30.6%) in the lateral decubitus position group, and 9 patients (24.3%) in the supine position group, though the difference was not statistically significant (p = 0.203). Among the reduction criteria we investigated, the TAD on the traction table was statistically significantly closer to the targeted measurement, with an average of 25.31 mm, compared with the other two positions (p = 0.000). The collodiaphyseal angle was significantly within the target range in the traction table-assisted supine group, averaging 130.720°, compared with the supine position (p = 0.000). In the traction table group, according to the modified Baumgaertner classification, 59.2% achieved a good reduction; according to the Ikuta classification, subtype N accounted for 69.4%; and according to the Cleveland–Bosworth classification, a center–center placement was present in 31% of patients. Conclusions: All three types of operation can be preferred according to the habits of the surgeon operating and the variables during the operation (the fracture type, history of orthopedic surgery, and the material components of the application phase). Accompanied by these data, we recommend the traction table operation as a priority and the lateral decubitus position operation as a second preference in compliance with the technical requirements.
