The elbow joint is very complex in composition and its function is easily affected, especially when the joint is injured or after fracture surgery, causing impairment to the joint’s extension and flexion activities, and even forearm rotation activities. Functional rehabilitation exercises are only suitable for patients in the early stage after surgery. When the function of the elbow joint is affected in the later stage, even the most perfect and painstaking functional exercises cannot fully restore the function of the elbow joint, and many patients can still move around on the CPM machine, but once they leave the machine, there is still little improvement in function. As a result, many physicians are unable to do anything about it and can only advise patients to accept a less than ideal functioning elbow joint. In fact, poor elbow function is not untreatable. Although the elbow joint is anatomically complex, there is a certain pattern of functional limitation (including ossifying myositis), and the use of a series of techniques to release the elbow joint, combined with post-operative individualized rehabilitation programs, has restored the function of the elbow joint in many patients, and a significant number of patients have fully recovered their extension and flexion functions, allowing patients to regain their confidence and return to work. self-confidence and return to work.
