B O U R P., D A P F., M E R L E M., F O U C H E R G., M I C H O N J. - - The inferior radio-ulnar joint in malunion of the lower extremity of the radius : therapeutic implications. Ann Chir Main, 1990, 9, n ° 4,261-270.
SUMMARY : Malunion of the lower extremity of the radius is frequently accompanied by a lesion of the inferior radio-ulnar joint marked by inversion of the inferior radio-ulnar index. Surgical treatment must always take this parameter into account and should attempt to correct it. The authors' preference in the treatment of malunion consists of Duparc osteotomy, in which the size of the graft is calculated in order to restore the inferior radio-ulnar index. If the correction is insufficient or in the case of moderate malunion, the authors propose the KapandjiSauv6 operation which allows better preservation of the wrist stability.

K A W A I H., S E D E L L. - - Excision of the lunate bone in Kienbock's disease. Report of seventeen cases. Ann Clair Main, 1990, 9, n ° 4, 271-275.
SUMMARY : We have performed excision of the lunate in 17 cases (partial excision of the lunate in two cases and total excision of the lunate in 15 cases) for the Decoulx stage III Kienb6ck's disease with an average follow-up of 11 years 7 months. Excellent and good results were obtained in 11 cases ont of 17 (65 per cent). After partial excision of the lunate, the shape of the lunate was conserved. After total excision of the lunate, the rearrangement of the remaining carpus maintained mobility and satisfactory force. Excellent and good results were obtained for pain in 14 cases out of 17. Total excision of the lunate gave poor results for the three heavy manual workers out of 12 manual workers after longterm follow-up.

S U M M A R Y : For nearly three years, the authors have treated scaphoid non-union by fixation with a double thread T.J. Herbert's screw. In the 25 cases a cancellous bone graft was used to fill the defect which would have left shortening of the scaphoid Twenty-two of the 25 cases, obtained rapid union, and 20 had a good or very good clinical result. One doubtful union and two cases of non-union occurred. One of these non-unions required revision. The

A L L I E U Y., BI~NICHOU M., CLI~MENCET F., O U A K N I N E R., M I O N Ch., C A N A U D B. - - A m y l o i d arthropathy of the hand in patients on haemodialysis. (In French). A n n Chit Main, 1990, 9, n ° 4, 282-289.
SUMMARY : Among 70 patients treated by hemodialysis for renal failure and operated for carpal tunnel syndrome, 17 presented with bone and joint lesions. Seven of them had destructive arthropathies of the distal interphalangeal joints, bilateral in 6 cases. Two radiological stages are described. Radiolucent lesions of the carpal bones were present in all the patients (~ carpal amyloidosis ,). The most frequent sites were around the radius-scaphoid-lunate and scaphoid-lunate joint spaces. Scaphoid-trapezoid-trapezium arthropathy was frequent, with dynamic instability in one .case. One patient had a pathological fracture of the lunate and scaphoid. Carpal tunnel syndrome was associated in all cases and dorsal wrist tenosynovitis in three cases. Amyloid arthropathy is more frequent in old patients on longterm hemodialysis. Amyloid deposits were shown in tendinous and joint synovial biopsies. The pathogenesis of amyloidosis is discussed. K E Y - W O R D S : A r t h r o p a t h y . - - Chronic hemodialysis. - Hand.
B R U N E L L I G., M O N I N I L., B R U N E L L I F. - - Direct muscular neurotization. Ann Chir Main, 1990, 9, n ° 4, 290-295.
SUMMARY : The authors present a technique of direct muscular neurotization consisting of re-innervation by direct implantation of a nerve into one or several muscles in cases of avulsion of the nerve supplying the muscle or traumatic or surgical avulsion of the neural part of the muscle. The biological basis for this operation is that a denervated muscle can accept a new innervation by a foreign nerve even in an aneural zone because its sensitivity to acetylcholine is present throughout the muscle, while, in a normally innervated muscle, sensitivity to acetylcholine is confined to the motor endplates. The results of 47 cases are presented : 42 of them obtained good or very good results. K E Y - W O R D S : Muscular neurotization. - - Denervated muscle. - - Reinnervation.
