The injuries of the femoral arteries were mistreated in 5 cases. The causes of the mistakes were resulted from: the initial cause of the injury was not carefully analyzed; the arterial injury was overlooked by the concomitant injuries, and the improper method of management was selected, as a result, 2 patients died from acute renal failure and the other 3 patients developed the complications of secondary thrombosis of the artery or rupture of the artery at the anastomotic site following repair. Of the 3 patients, 2 patients had recovered following reoperation and the other 1 patient had lost his limb from amputation. It should be emphasized that all of the following key points might avoid the mistakes occurred in the management of the injury of the femoral artery: (1) early diagnosis; (2) debredment of arteral end; (3) in infections wounds, insted of vein transplantation bypass technique should be done.
The influence on the wrist stability following ulnar head resection (Darrach s procedure)was studied. A series of X-ray films and arthrography of the wrist joint were taken before and after ulnar head re- section. The results showed that after ulnar head resection the radial deviation increased 3 degree(Plt;0.01). and the ulnar deviation 11.92 degree (Plt;0.001). The position of the lunate remained unchanged. Arthrography of the wrist joint demonstrated that 11 specimens had injury of the triangular fibrocartilage.The stability of the wrist joint would no doubt be certainly affected following the ulnar head resction.
