Aim:
The surgical reconstruction of the dorsiflexion of the wrist and the abduction of the thumb in paralyzed radial nerve for the improvement of the useability of the hand is described. Likewise, the early functional subsequent treatment is described. Indications and contraindications are represented in detail.
Method:
Between October 1997 and May 2000 we treated 10 patients by the following method: The musculus flexor carpi ulnaris tendon is cut near the pisiform bone, transferred subcutaneously and fixed on the tendons of the extensor communis digitorum communis muscle. The tendon of the palmaris longus muscle is fixed on the tendon of the extensor pollicis longus muscle. After the swelling in the hand has subsided, the patients are supplied with a dynamic splint in order to avoid adhesions.
Results:
According to the score suggested by Haas, 9 patients achieved a very good result (median: 30 degrees dorsiflexion), one patient had a good result (0 degree dorsiflexion).
Conclusion:
Adhesions could be avoided and the time of rehabilitation could be shortened by the operation method described. The operations result in an improvement of hand function and as well as patient satisfaction.
