To determine the value of an anatomic distal radio-ulnar joint ligament reconstruction (Adam's technique) in patients who suffer chronic pain related to distal radio-ulnar joint instability.

Twelve patients who suffered from chronic pain related to distal radio-ulnar instability and underwent a reconstruction of the distal radio-ulnar ligament using a free tendon technique were enrolled in this study. The mean follow up period was at least 1 year. In all cases, injury to the distal radio-ulnar joint was present, which had been previously treated with conservatively. There was no evidence of arthritis on the distal radio-ulnar joint radiologically. The radiological radio-ulnar space and displacement of the ulnar head, clinical pain, stability, the range of motion and the grip power were measured before and after surgery (follow up 1 year).

No displacement of the distal radio-ulnar joint or prominence of the ulnar head was observed radiologically in 10 cases, and only partial subluxation was present in 2 cases. Clinically, the pain disappeared in 8 cases and the stability of the joint was recovered in 8. The mean pronation, supination range and grip power increased by an average of 73, 71 ° and 11.7 kg, respectively.

In treating distal radio-ulnar joint instability related to chronic pain, Adam's technique using palmaris longus, which is an operation using a single incision, and by restoring the distal radio-ulnar ligament anatomically can decrease the level of pain and recover the range of motion. Therefore, it is a good method worth considering in this situation.
