Abstract 1-Abstract
Metacarpal fractures are common hand injuries that often require surgical intervention for significant displacement or instability. Various fixation methods such as Kirschner wires, plates, external fixators, and intramedullary screws are used, each with potential complications. Understanding the anatomy and biomechanics of the metacarpal is crucial for successful management. We present a case of a 36-year-old man with a second metacarpal fracture following a motorcycle accident. After initial pinning failed, open reduction with internal fixation was performed, later replaced by an intramedullary headless screw. Subsequent physiotherapy led to a successful outcome with normal function and union. Surgical techniques for metacarpal fractures include pinning, plating, and intramedullary devices, each with specific indications and considerations. While pinning is cost-effective and minimally invasive, plating is preferred for certain fracture patterns, and intramedullary devices allow early mobilization. In our case, the intramedullary screw proved effective for delayed Union treatment after previous failures. Larger studies are needed to validate its efficacy and explore potential complications. This case highlights the importance of individualized treatment strategies in complex metacarpal fractures.

Abstract AbstractAbstract
Purpose: The aim of this study was to assess the incidence and patterns of meniscus tear accompanying the posterior cruciate ligament (PCL) lesion.
Method: 81 patients with a diagnosis of chronic PCL tear that underwent PCL reconstruction surgery were included in the study. The patients’ files were reviewed. The location and grade of cartilage damage, the location and pattern of meniscus tears, the interval between diagnosis and surgical procedure, and the treatment method were collected.
Result: The average interval between the incidence of trauma and surgery was 16.73±33.1 months. The interval between the incidence of trauma and surgery in patients with meniscal tear was 24.6±4.86 months and in patients without meniscal tear was 12.76±2.1 months Meniscal tear was detected in 27 patients (33.3). It was in medial meniscus in 19 (23.5%) and in lateral menisci in eight (9.9%) patients. The most common site of meniscal tear was root tear and mostly avulsion of meniscus root. Of these, 6 patients had posterior root avulsion of medial menisci. Cartilage lesions were detected in 14 patients (17.3%).
Conclusion: Based on the present study. The most common pattern of meniscal tear in cases of PCL tear is posterior medial meniscus avulsion tear. Such a tear deteriorates overtime.
