[Arthroscopic treatment for post-traumatic chronic wrist pain].

Objective: To explore the therapeutic effects of arthroscopy for post-traumatic chronic wrist pain.

Methods: From February 2007 to June 2010, 12 patients with post-traumatic chronic wrist pain treated with arthroscopy were reviewed. Among the patients, 9 patients were male and 3 patients were female, ranging in age from 19 to 47 years, with a mean of 35.6 years. After physical examinations or MR abnormal findings, all the patients underwent wrist arthroscopic examination and treatment. Eight patients with tear in the central area of the triangular fibrocartilage complex (TFCC) underwent endoscopic partial resection. Two patients with relaxation of inter-carpal ligament after injury underwent radiofrequency shrinkage. One patient with distal radioulnar joint instability was treated with Kirschner fixation through distal radius and ulna in the neutral forearm rotation after clean-up of wrist joint, and also fixed with long arm cast immobilization for 6 weeks. One patient with ulnar impaction syndrome was treated with wrist clean, border modeling of triangular cartilage plate, partial resection of distal ulna.

Results: All the patients were followed up with an average duration of 10 months. Modified Mayo wrist score were evaluated from preoperative mean of (51.67 +/- 15.27) ( 25 to 75 scores) to postoperative mean of (77.92 +/- 10.54) (65 to 95 scores). Eleven patients recovered to normal work.

Conclusion: Arthroscopy is an effective method for patients with post-traumatic chronic wrist pain which can diagnosis and cure the injuries under arthroscopy.
