Pronator Syndrome involves compression of the median nerve in the forearm, often affecting middle-aged women. It typically presents with forearm pain and a positive Tinel sign. Management starts conservatively with rest and splinting, progressing to surgery if symptoms persist.
Thumb MCPJ UCL injuries range is typically diagnosed with stress tests and imaging. Conservative treatment for partial tears to surgical repair for complete tears and avulsions.
Seymour fractures are open, displaced distal phalangeal fractures in children, often caused by crushing injuries and associated with nail bed damage. Treatment includes irrigation, debridement, reduction, fixation, and antibiotics.
Ring avulsion injuries range from lacerations to amputation, typically caused by a ring catching on an object. Proper assessment and treatment depend on the severity, involving everything from suturing to amputation.
