A comminuted fracture of the medial malleolus combined with a talar neck fracture is a uncommon finding. Surgeons are often unaware of its unique injury mechanism, which complicates fracture reduction and fixation and may cause potential complications during and after surgery. This report presents […]

A 32-year-old man sustained a rare and complex injury pattern representing an anterior glenohumeral fracture dislocation with critical intra-articular glenoid bone loss, and a double disruption of the superior shoulder suspensory complex (acromion + coracoid fractures), following a fall. To restore […]

Excessive distal clavicle resection can result in severe bone loss and disruption of the coracoclavicular (CC) ligament attachment, leading to significant vertical instability of the acromioclavicular joint. The optimal surgical approach in such cases remains controversial due to the technical […]
