Article Synopsis
- - This study aimed to create a convolutional neural network (CNN) to detect and classify fractures, focusing on specific characteristics like greater tuberosity displacement and neck-shaft angle, using plain X-rays.
- - The CNN was trained with over 1,700 X-rays from Australia and validated with data from the Netherlands, comparing results with CT scans evaluated by experts.
- - The CNN demonstrated a high detection accuracy of 94% for fractures, but less effectiveness in identifying specific fracture characteristics, particularly showing lower performance for greater tuberosity displacement and neck-shaft angles.
Article Synopsis
- The study investigated how different pain management techniques—intrathecal morphine (ITM), adductor canal block (ACB), and their combination—affect recovery after Total Knee Arthroplasty (TKA).
- It analyzed data from 1006 patients to assess pain levels, mobility times, and hospital stay lengths based on the type of analgesia received.
- Results showed that the combination of ITM and ACB led to better pain control, reduced opioid use, and faster mobilization compared to using either method alone.
Article Synopsis
- * After three rounds of surveys, 18 out of 68 factors were identified as influential, with stable consensus on factors that favor operative treatment including professional athlete status and specific fracture characteristics.
- * Most disagreement arose regarding treatment for certain injuries, especially those involving an anterolateral coronoid tip fracture, indicating a need for more clarity in treatment guidelines among surgeons.
Purpose: To (1) evaluate surgeon agreement on plating features (position and screw length) in virtual 3D planning software, (2) describe outcomes (fracture reduction, plate position, malpositioning of calcar screws and screw lengths) of plate fixations planned with routine pre-operative assessment (2D- and 3D CT imaging) and those planned with dedicated virtual 3D software of the same proximal humerus fracture.
Methods: Fourteen proximal humerus fractures were retrospectively reduced and fixed with virtual planning software by eight attending orthopaedic surgeons and compared to the true surgical fixation with post-operative computed tomography (CT) scans. Reduction differences were quantified using CT micromotion analysis.
Aims: Paediatric triplane fractures and adult trimalleolar ankle fractures both arise from a supination external rotation injury. By relating the experience of adult to paediatric fractures, clarification has been sought on the sequence of injury, ligament involvement, and fracture pattern of triplane fractures. This study explores the similarities between triplane and trimalleolar fractures for each stage of the Lauge-Hansen classification, with the aim of aiding reduction and fixation techniques.
