Background: The purpose of this study is to describe the macroscopic and radiological changes on the fifth finger related to mobile phone use and to evaluate the effect of size and weight of the device and the average time spent using the smartphone on these morphological alterations. Methods: One-hundred and one patient were included in the study. Age, weight, height, education, mobile phone data and digital photographs used in this cross-sectional study were obtained from interviews with the participants in an outpatient orthopedics clinic setting. Digital photographs of the dorsal aspects of both hands were taken with an iPhone X ® (dual 12-megapixel wide camera). The DIP joint angle of the fifth finger was measured on computer software (Image J® version 1.46, National Institute of Health, Bethesda, MD) separately for digital photographs and AP hand X-rays. Results: The proportion of smartphone usage time over 4 hours was significantly higher in patients with complaints than patients without complaints (p<0.05). The mean time of smartphone use over 4 hours was significantly higher in patients with shape discrepancy than in patients without shape discrepancy (p<0.05). Conclusion: Smartphone use of more than 4 hours per day, regardless of size and weight, can cause deformity of the fifth finger, which may disturb the patient even if it does not cause radiologically changes.

Background/Objectives: Trigger finger is a common cause of hand pain and functional limitation. Although open A1 pulley release remains the standard surgical treatment, ultrasound-guided percutaneous needle release (UGPR) has emerged as a minimally invasive alternative. This study aimed to compare the clinical effectiveness and safety of UGPR with open surgery. Methods: In this prospective, randomized controlled trial, 146 patients with Green stage 2–4 trigger finger were randomly assigned to UGPR (n = 75) or open release (n = 71). Pain (VAS), functional status (QuickDASH), and symptom severity (Nirschl Phase Rating) were assessed preoperatively and at postoperative day 3, 1, 6, and 12 months. Grip strength was measured with a digital pinchmeter, and ultrasonographic evaluation of A1 pulley and flexor tendon thickness was performed preoperatively and at 12 months. Subgroup analyses were conducted to address the imbalance in thumb distribution. Results: Both groups showed significant postoperative improvements in VAS, QuickDASH, and Nirschl scores (p < 0.05 for intragroup comparisons), with no significant differences between groups at 12 months (p > 0.05). At the one-year follow-up, grip strength was significantly greater in the UGPR group (p = 0.008). Ultrasonographic evaluation revealed greater MCP tendon thickness in UGPR, without clinical impact. Subgroup analyses confirmed comparable functional outcomes in thumb-only and non-thumb cases. Four revisions occurred in the UGPR group (incomplete release, recurrent tenosynovitis, flexor tendon rupture, and neurovascular injury), while none were observed in the open group. Conclusions: UGPR and open release provide comparable long-term outcomes in the treatment of trigger finger. UGPR offers the advantages of being minimally invasive and preserving grip strength, although it carries a small risk of incomplete release and procedure-related complications. Patient preference, surgeon expertise, and digit type should guide treatment selection.

Purpose: Developmental dysplasia of the hip (DDH) requires timely, guideline-concordant decisions to prevent long-term morbidity. ChatGPT-5.0 may support clinicians—especially where pediatric orthopedic expertise is limited, but their reliability across typical and discordant presentations is uncertain. This scenario-based validation study evaluated the accuracy of ChatGPT-5.0’s management recommendations for DDH using 30 structured clinical cases and compared these outputs against AAOS (2022) and AAP (2016) guidelines. Methods: Scenario-based validation using 30 unique cases: 20 concordant (aligned clinical and imaging findings) spanning Graf and acetabular index-based ages, and 10 mismatch scenarios with correct examinations but intentionally erroneous radiology. The primary outcome was guideline-concordant accuracy, categorized as correct, partially correct, undertreatment, overtreatment, or incorrect. Secondary outcomes included the effect of error-aware prompts and multilingual consistency. Results: In concordant scenarios, guided ChatGPT achieved 100% correct, while non-logged-in ChatGPT achieved 95% with one overtreatment. In mismatch scenarios, guided ChatGPT frequently tends toward overtreatment and failing to recommend repeat ultrasound or urgent pediatric orthopedic consultation. Non-logged-in ChatGPT performed better in mismatch cases but similarly under-emphasized remeasurement/consultation. Error-aware prompts did not materially alter recommendations in either environment. Swahili queries produced outputs clinically identical to English responses. Conclusions: ChatGPT-5.0 provides reliable, guideline-concordant guidance for DDH when clinical and radiologic data are concordant, supporting potential use as a decision aid in settings without immediate pediatric orthopedic access. Safe clinical implementation requires human oversight and integration of guideline-based safety checks to prevent mismanagement in ambiguous cases.

Protez eklem enfeksiyonları kalça ve diz artroplastisi sonrası sık görülen bir komplikasyon olup Pasteurella cinsi bakterilere bağlı olarak nadir de olsa karşımıza çıkmaktadır. Özellikle bağışıklığı baskılanmış ve hayvanlarla yakın teması bireylerde ortaya çıkan bu enfeksiyonlar hakkında literatürde yeterli düzeyde çalışma yoktur. Bu derleme çalışmasında, Pasteurella cinsi bakterilere bağlı gelişen protez eklem enfeksiyonları konusunda literatürün derlemesini ve uygulanan tedaviler ile tedavi sonuçlarının gözden geçirilmesi amaçlandı.
