[Long-term results of the palmar arthrolysis of the proximal interphalangeal joint].

BACKGROUND

Palmar arthrolysis of the proximal interphalangeal joint is seldom carried out as an isolated treatment of contractures. The operation is usually performed in connection with treatment for a primary illness. Although intra-operative extension of the interphalangeal joint is normally completely achieved, the postoperative results show deficiencies in the extension. METHODS AND CLINICAL MATERIAL: The long-term results of 110 arthrolyses of the proximal interphalangeal joint of 102 patients are presented. The operations were performed on average 4.6 years ago. The analysis was made with standard questionnaires and self-made drawings along the side of the patients' maximally extended finger.

RESULTS

"Successful operations" where performed on 76% of all released joints. The angle of the contracture was reduced by at least 10 degrees in these joints. The long-term results were compared in conjunction with results of injuries or operations of other illnesses: M. Dupuytren (primary), relapses of M. Dupuytren, lesions of the flexor tendons, camptodactyly, results of injuries due to the consequences of operations or other illnesses. The results in the group of lesions of the flexor tendons were on the whole unsuccessful.

CONCLUSION

Even though thorough postoperative hand therapy(physiotherapy and use of splints) and above-average co-operation of the patients are prerequisites for a successful arthrolysis, it can be seen that the elimination of the underlying illness is of primary importance.
