RESUMEN

BACKGROUND: When performing partial toe-transfer flaps with a short vascular pedicle, as the flap becomes smaller, the likelihood of securing veins in the flap decreases. The purpose of this study was to clarify how frequently the partial toe-transfer flap with a short pedicle (free vascularized half-big toenail flap) contains veins and elucidate how frequently we can secure the veins with an artery via the first web space approach alone, using the Genial Viewer (a near-infrared light transmission imaging device). METHODS: We observed the dorsal vein images of the bilateral big toes of 250 volunteers (male, n = 125; female, n = 125) using the device. We counted the total number of dorsal veins in the big toe, the veins that crossed the margin of the region equivalent to the half-big toenail flap, and the veins that branched off from the fibular side of the flap area. An unpaired Student's t-test was used for the statistical analyses. RESULTS: All of the dorsal big toes contained veins. The mean number of the veins was 2.3 (range, 1-4). Branched-off veins were observed in the area equivalent to the half-big toenail flap in 496 (99.2%) of the big toes, and the mean number of veins was 1.9 (range, 0-4). In four cases, the region contained no veins (unilaterally). Branched-off veins were observed in the first web space in 440 (88.0%) of the big toes, and the mean number of veins was 0.9 (range, 0-2). CONCLUSIONS: The present study indicated high consistency of the veins in partial toe-transfer flaps with a short vascular pedicle and the high possibility of harvesting a flap with only exposing the first web space. In addition, in most cases, the flap will include one or, at most, two veins in the first web space.

RESUMEN

Objective To investigate the methods and the therapeutic effects of groin flap and stylus recurrent branch of radial artery flap for the repair of severely contracture of the first web space. Methods From March 2007 to six 2009,45 patients with severely contracture of the first web space received treatment of groin flaps and stylus recurrent branch of radial artery flaps, with 6 to 12 months clinical observation. Among then, 33 patients received treatment of groin flaps, 12 patients received treatment of stylus recurrent branch of radial artery flaps, and 28 patients received the first web space widening as well as functional reconstruction of thumb abduction. Results Most of the flaps healed by first intention but also with distal necrosis for 3 stylus recurrent branch of radial artery flaps and 1 groin flap. And the weth of the first web space of all patients were more than 90% of comparison. From clinical observation,function of opposition recovered well. While some groinflaps got a litte fat and clumsy .The color of most flaps was as similar as normal besides, some groin flaps occurrenced pigmentation. Conclusion Children and adults below 50 yesrs should choose the groin flap, and aged people and adults more than 50yesrs shuould choose the stylus recurrent branch of radial artery flap firstly.

RESUMEN

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.

RESUMEN

Objective To introduce our experiences of reconstruct the first web space using flaps.Methods One hundred and twelve patients sustained contracture of the first, summarized the indications of different flaps in coverage of the first webspace and their prognosis of these flaps were retrospectively reviewed.Results The local flaps, such as double Z-plasty or Z-plasty, were suitable to cover minor contracture of the first webspace; the dorsal flap arising from the index finger was suitable for the coverage of the medium contracture, and the posterior interosseous artery flap or the reverse antebrachial island flap based on the dorsal branch of the anterior interosseous artery suitable for the severe cases. Conclusion The usage of flaps is important to resume the cosmetic shape and function of the first webspace after release of the contracture of the first webspace.

RESUMEN

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.
