Most patients recover well following fingertip injuries. Outcomes vary along a spectrum, influenced by both pathophysiological severity and psychosocial factors, which strongly influence patient-reported outcome measures (PROMs). General instruments (e.g., Disabilities of the Arm, Shoulder, and […]

Osteoarthritis (OA) is a progressive and chronic joint disorder characterized by cartilage degradation, joint inflammation, and pain, leading to reduced mobility and quality of life. One of the major challenges in OA management is the early diagnosis and effective monitoring of disease progression, […]

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 […]
