Thrower elbow, also known as medial collateral ligament sprain, affects the elbow's medial collateral ligament. The elbow collateral ligament injury often causes elbow pain and movement difficulty.
The common symptoms include: bending pain, forearm discomfort, swelling, wrist pain, finger numbness, medial elbow instability. Resting, cold therapy and other non-surgical treatment can often alleviate the symptoms. If left untreated, this may lead to chronic pain.
Repetitive medial stress is the major cause, as it can cause elbow joint injuries, especially the collateral ligaments. The common risk factors include: overarm-throwing sports, baseball, tennis, racket sports, repetitive valgus movements.
