The treatment of comminuted distal humeral fractures with free osteochondral fragments is challenging. Osteochondral fragments should be retained whenever possible and secured with implants buried beneath the articular surface to obtain a uniform articular surface. Headless compression screws and K wires are commonly used for this purpose. However, certain complications have been reported with these fixation implants in case of the non-union and osteolysis of the fragments such as migration and cartilage damage. Fixation of osteochondral fractures in distal humeral fractures using bioabsorbable implants has been rarely reported in the current literature. Herein, a patient who sustained a comminuted distal humeral fracture with multi-fragmentary osteochondral fragments is presented, and treatment with magnesium bioabsorbable compression screws is discussed.

Background: Accurate deformity classification and fusion-level planning are essential in adolescent idiopathic scoliosis (AIS) surgery and are traditionally guided by Cobb angle measurement and the Lenke system. Multimodal large language models (LLMs) (e.g., ChatGPT-4.0; Claude 3.7 Sonnet, Gemini 2.5 Pro, DeepSeek-R1-0528 Chat) are increasingly used for image interpretation despite limited validation for radiographic decision-making. This study evaluated the agreement and reproducibility of contemporary multimodal LLMs for AIS assessment compared with expert spine surgeons. Methods: This single-center retrospective study included 125 AIS patients (94 females, 31 males; mean age 14.8 ± 1.9 years) who underwent posterior instrumentation (2020–2024). Two experienced spine surgeons independently performed Lenke classification (including lumbar and sagittal modifiers) and selected fusion levels (UIV–LIV) on standing AP, lateral, and side-bending radiographs; discrepancies were resolved by consensus to establish the reference standard. The same radiographs were analyzed by four paid multimodal LLMs using standardized zero-shot prompts. Because LLMs showed inconsistent end-vertebra selection, LLM-derived Cobb angles lacked a common anatomical reference frame and were excluded from quantitative analysis. Agreement with expert consensus and test–retest reproducibility (repeat analyses one week apart) were assessed using Cohen’s κ. Evaluation times were recorded. Results: Surgeon agreement was high for Lenke classification (92.0%, κ = 0.913) and fusion-level selection (88.8%, κ = 0.879). All LLMs demonstrated chance-level test–retest reproducibility and very low agreement with expert consensus (Lenke: 1.6–10.2%, κ = 0.001–0.036; fusion: 0.8–12.0%, κ = 0.003–0.053). Claude produced missing outputs in 17 Lenke and 29 fusion-level cases. Although LLMs completed assessments far faster than surgeons (seconds vs. ~11–12 min), speed did not translate into clinically acceptable reliability. Conclusions: Current general-purpose multimodal LLMs do not provide reliable Lenke classification or fusion-level planning in AIS. Their poor agreement with expert surgeons and marked internal inconsistency indicate that LLM-generated interpretations should not be used for surgical decision-making or patient self-assessment without task-specific validation.

The purpose of this study was to introduce and evaluate the Descriptive Ankle Fracture Classification (DAFC) system, a novel alphanumeric method for categorizing ankle fractures and fracture dislocations, and to assess its reliability and prognostic value compared to traditional classification systems (AO/OTA, Weber, and Lauge-Hansen). A retrospective review was conducted on 90 patients who underwent surgical treatment for ankle fractures. Four observers of varying experience levels classified the fractures using the DAFC, AO/OTA, Weber, and Lauge-Hansen classification systems. Interobserver and intraobserver reliability were evaluated using Fleiss’ Kappa coefficient. Functional outcomes were assessed with the American Orthopaedic Foot & Ankle Society (AOFAS) and Olerud Molander Ankle Score (OMAS) systems, and comparisons were made across classification systems to determine prognostic value. The DAFC system demonstrated superior interobserver reliability, particularly for medial malleolus fractures (Kappa = 0.935–0.954) and syndesmotic injuries (Kappa = 0.873–0.891), compared to the other systems. Intraobserver reliability was consistently high across all categories in the DAFC system, with Kappa values ranging from 0.967 to 1.000. Functional outcomes revealed significant associations with the DAFC classification: patients with complete dislocation (D2) had significantly lower AOFAS and OMAS scores than those without dislocation (D0) (P = 0.011), and those with larger posterior malleolus fractures (P2) had poorer OMAS scores (P = 0.014). No statistically significant differences in AOFAS or OMAS scores were observed across AO/OTA, Weber, or Lauge-Hansen classifications. The DAFC system offers a reliable and comprehensive framework for ankle fracture classification, with the added benefit of prognostic insights, particularly regarding dislocation and posterior malleolus involvement. Its high interobserver and intraobserver reliability, even among observers with varying experience, suggests that the DAFC system is valuable for clinical use. Future research should focus on validating these findings in larger cohorts and assessing the DAFC system’s impact on long-term patient outcomes. Level IV, Retrospective cohort.

Background: Recalcitrant plantar fasciitis (PF) refers to persistent heel pain lasting ≥ 6 months despite appropriate conservative management, including physical therapy, orthotics, and pharmacological interventions. This study aimed to compare the clinical efficacy and safety of corticosteroid injection (CI), radiofrequency ablation (RFA), and their combination in patients with recalcitrant PF.Methods: In this retrospective study, a total of 156 patients with ultrasonographically confirmed plantar fasciitis, experiencing heel pain for at least 6 months and unresponsive to ≥ 3 months of standard conservative therapy, were included; 52 received RFA, 50 received CI, and 54 underwent combined therapy. Pain intensity (visual analog scale [VAS]), functional status (Foot Function Index [FFI], Roles and Maudsley score [RMS]), plantar fascia thickness (PFT), and relapse rates at 12 months were assessed. Within‐group and between‐group differences were assessed using appropriate nonparametric tests, and relapse rates were compared accordingly.Results: All treatment modalities improved VAS, FFI, RMS, and PFT at 6 months (p < 0.001). VAS declined from 6.73 to 6.81 at baseline to 1.62 in the RFA group and 1.83 in the combined group, whereas remaining at 6.56 in the CI group. FFI dropped from ∼52 to 21.50 and 17.57 in the RFA and combined groups but remained at 46.62 in the CI. PFT decreased from ∼6.2 mm to 3.29, 2.71, and 2.95 mm, respectively. Relapse occurred in 12 (23.1%), 19 (38.0%), and 8 (14.8%) patients in the RFA, CI, and combined groups. Between‐group differences were significant at 6 months (p < 0.001). No major adverse events were observed.Conclusion: Both CI and RFA are effective in recalcitrant PF, but their combination provides superior and more durable improvements in pain, function, and fascia morphology, with the lowest relapse rates. Ultrasound‐guided combined therapy suggests a safe, practical, and effective treatment option for patients unresponsive to conservative measures.

Objective: Terrible triad elbow ınjury (TTEI) is a complex trauma characterised by posterolateral dislocation, radial head fracture, and coronoid process fracture. Such injuries can lead to elbow instability and loss of function. The role of anterior capsulodesis surgery in the treatment of TTEI has not been fully established. The aim of this study was to evaluate the efficacy of anterior capsulodesis in patients with TTEI, to see its effect on elbow functional scores, to analyze possible post-operative complications, and to compare them with the literature. Materials and Methods: This retrospective study analyzed 14 patients diagnosed with TTEI between 2017 and 2022. Patients with O’Driscoll type I-II and Regan–Morrey type I-II fractures were treated with a treatment protocol that included radial head fixation, lateral collateral ligament repair, and transosseous anterior capsulodesis. The mean follow-up was 23.2 months. Surgical outcomes were assessed using the Mayo Elbow Performance Score, Disabilities of the Arm, Shoulder, and Hand, and Broberg–Morrey classification. Results: This study suggests that endobutton fixation of O’Driscoll and Regan–Morrey type I-II coronoid fractures in the treatment of TTEI has a positive effect on elbow function in the medium and long term. In particular, for fractures with limited coronoid involvement and capsular avulsion, anterior capsulodesis has been shown to improve functional outcomes and reduce the incidence of post-traumatic osteoarthritis. Conclusion: Anterior capsulodesis is an effective option for the treatment of TTEI in terms of improving elbow function and reducing complications. When we reviewed the available studies in the literature, we concluded that anterior capsulodesis is a valuable procedure in the treatment of TTEI.
