应用桡动脉鼻烟窝皮支皮瓣修复虎口挛缩

Objective To summarize and investigate the therapeutic effects of reconstruction of contracture of the first web space with snuff-box flap. Methods Eighteen patients with contracture of the first web space were treated by snuff-box flap. The width and the angle of the first web space was 19 mm and 20°on average. According to the first web space skin defects, the flap designed to nasopharyngeal fossa centers as rotation point, the radial line when the forearm in the neutral position as the axis. Results The followedup for 5-26 months revealed that 17 flaps had a success, but 1 case was partly necrosis. The width of the first web space was augmented by an aveage of 45 mm, the angle of the first web space was augmented by an average of 50°. Conclusion It is ralatively simple and reliable to repair the contracture of the first web space using the snuff-box flap.     

应用皮瓣移植治疗重度虎口挛缩的体会

Objective To summarize the result of several kinds of flaps treated to first web space contraction. Methods Thirty-two cases of sever contracture of the first web space were treated between September 2000 and March 2009. Ultrathin groin flap, blood vessel pedicle reverse-flow island flap, neurocutaneous flap of the forearm, and free skin flap were used. The area of flaps were 3.0 cm × 5.0 cm-4.5 cm× 8.0 cm.The therapeutic result was observed by 3-12 months follow-up. Results There were partial necrosis at the distal part of flap in 1 case of nerve nutritional vascular pedicle skin flap and 1 case of ultrathin groin flap.The raw surface was healed by free skin grafting. The other flaps were all survived. There was some contraction observed in some patients after the K-wire released. The width of the first web space was augmented to an average of 50 mm (35-60 mm) and account to 80% to the uninjured side. The angle of the first web space was increased to an average of 70°(45°-80°). The contracture was improved significantly. The abduction and opposition function of thumb were restored. There was some degree decrease of grasp strength. The patients can fulfil daily life and partial work. But sensation was not good in some patients. The contour of the flaps:the contour of ultrathin groin flap was good. The contour of flaps in 3 cases of island skin flaps, 1 case of nerve nutritional vascular pedicle skin flap and 2 cases of free flaps were trimmed again in order to be improved. Conclusion The sever contracture of the first web space could be treated by different kinds of flaps, the suitable management should be chosen according to the specific situation.

手部挤压伤后虎口挛缩的早期防治

Objective To introduce the therapeutic measure of preventing the first web contracture after hand crush injury in early stage. Methods Three types were divided according to the traumatic condition in 57 cases: closed injury, open injury and with blood vessel of thumb or fingers injury, and used different method such as closing injury postpone, opening the first web by kischner wire or mini-external fixation splint and covered by local or island flap to cure each type in primary and early stage, after 6 months, measured the width and angle of the first web. Results Forty-one cases were followed-up after 3 months - 2 years,abduction and opposition of the thumbs were fine, the average of width and angle of the first web were (5.89 ± 0.58)cm and (87.85 ± 6.03)°. Conclusion The key points of preventing the first web contracture after crush injury are opening the first web that being covered by local flap and to use splint in primary stage.

带血管蒂腓骨头骨骺截骨整形重建内踝的应用解剖与临床应用

Objective To provide an anatomical basis for repairing the medial malleolus with bone-severed vascularized fibular head epiphysis, and to explore the effect of clinical application with this method. Methods Figures of fibular head and medial malleolus were measured on 20 fresh lower limbs specimens of child age from 2 to 12 years old, then bone-severed formula was deduced. The bone-severed composite fibular head epiphysis to repair the defect of medial malleolus were carried for 6 child patients of emergency or post-poned cases on one stage. Obersved the clinical effect by following-up. Results The angle between fibular head and stem (M) was(170±8)°, angle of fibular head sadacc(N) was (145 ±6)°, length(1.5±0.2)cm and width (1.4±0.2)cm; angle between medial malleolus and stem(1) was(152±8)°, length of the articular surface of medial malholus was(1.25 ± 0.2)cm and width (1.25 ± 0.2)cm. Angle between defect surface and tibia was(Q). Formula: angle of bone-severing X = L-N-Q, and apex at the upper 1/6 of the reversed articular surface of fibular. 6 cases with this method was completed, all healed at stage one, following-up 1 to 3 years, medial malleolos developed well and no epiphysis ossification anticipation, and the ankle joint has no inversion with its loadind and walking function good. Conclusion The fibular head epiphysis and the medial malleolus differ in shape to some extent, but good donor can be got by bone-severing, can repair the epiphysis and soft tissue defect of the medial malleolus at one stage with additional flap, developing with the child at the same time, it is a perfect method to reconstruct the traumatic defect of child medial malleohs.
