[Surgical treatment in De Quervain's tenosynovitis. About 20 cases]. / Traitement chirurgical de la ténosynovite de De Quervain. A propos de 20 cas.

INTRODUCTION: The De Quervain's tenosynovitis is an inadequacy into the first extensor compartment between the osteo-fibrous tunnel and the tendons. This mechanical conflict generates a tenosynovitis of the extensor pollicis brevis and the abductor pollicis longus tendons in first dorsal extensor compartment of the wrist. PATIENTS AND METHODS: The authors report a retrospective study of 20 patients who have been treated by a longitudinal surgical approach. The mean age was 49 years old with a net female predominance. The Finkelstein's test was positive in all cases. All patients were treated operatively by incision of the sheath, which was sufficient to unwind the dorsal compartment tendons. The sheath palmar flap has been sutured with skin (Le Viet plasty) to avoid a further tendons luxation. RESULTS: At three years follow-up, the functional results were good in all the patients. However, non-aesthetic scars were noticed in three patients. We did not notice neither a case of anesthesia of the radial nerve nor a tendinous luxation in our series. DISCUSSION: The stenosing tenosynovitis of the first dorsal extensor compartment of the wrist is a relatively frequent pathology in the young woman. We use a longitudinal surgical approach to avoid the radial nerve lesions. Le Viet procedure using the palmar flap of the pulley fixed to the dermis works as a barrier and maintains the tendons sliding on the radial styloid groove.

[Luxatio erecta of the shoulder. Report of eight cases]. / Luxation erecta de l'épaule (à propos de huit cas).

The luxatio erecta is a rare form of shoulder dislocation frequently described in young patients. The purpose of our study is to review the mechanism of this affection as well as its clinical, radiographic and therapeutic features. We also report eight cases of luxatio erecta observed between 1995 and 2006. We report six males and two females with an average age of 40 years. The left shoulder was dislocated in seven cases and a direct mechanism was reported by two patients. All of our cases presented with the typical attitude described for this dislocation; an upper limb in fixed abduction with the hand raised and inability to bring the elbow back to the body. No neurovascular injury was reported in this study. Radiographic examination showed inferior dislocation of the humeral head and the axis of the shaft above the horizontal line in all of our cases. The treatment consisted of closed reduction under general anaesthesia followed by a Dujarier's bandage for three weeks. Luxatio erecta is the commonest type of inferior dislocation. Its mechanism is a fall on the upper limb in great abduction or antepulsion. The clinical diagnosis is easy, confirmed by an anteroposterior radiograph. The functional long-term prognosis is excellent.
