Knee osteoarthritis (KOA) is a highly prevalent degenerative joint disease worldwide and an important cause of disability. Currently, medication and surgical interventions are commonly used in clinical practice, but there are limitations such as significant side effects and high medical costs. Tai […]

Complex distal tibial injuries with segmental bone loss, joint destruction, and osteomyelitis present a formidable limb salvage challenge. A novel technique using circular external fixation with trifocal balanced cable transport combined with primary ankle arthrodesis is described. This technique […]

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 […]

Operative Repair of Supination Adduction Ankle Fracture - Surgical Technique

A mixed-reality image-based navigation system was used intraoperatively to guide bone loss […]

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 […]
