Double reverse-flow island flaps for two adjacent finger tissue defect   总被引:1,自引:0,他引:1  
INTRODUCTION: Soft-tissue reconstruction of fingertip injuries remains a challenge for hand surgery. Tissue loss of multiple digits is a serious problem for hand surgeons. Surgical possibilities include regional, distant and local flaps. In this study, five patients presented with tissue loss of two adjacent fingers and were treated by double reverse-flow island flaps. MATERIALS AND METHODS: The surgical technique is an application of the reverse-flow homodigital island flap for two adjacent finger tissue defects. Instead of one flap, double island flaps are applied to two adjacent finger tissue defects. The flaps are raised from the lateral or medial palmar surface of the proximal phalanx level. Anastomoses between the radial and ulnar digital arteries at the distal interphalangeal joint level are preserved. RESULTS: Three of the patients had tissue defects at the fingertip. In these cases, digital nerve anastomosis with the counter lateral digital nerve made the flaps sensitive. In two patients, the tissue defect was on the dorsum of the middle phalanx level. In these cases, the flaps were non-sensitive. Neither infection nor flap failure was seen in the patients. Sensitive function was satisfactory in fingertip applications. CONCLUSION: The reverse-flow homodigital island flap is a commonly used surgical technique for tissue defects in the fingers. The double reverse-flow island flaps involve the application of this technique for two adjacent fingers. The important point in the surgical technique is that the vascular supply of the two flaps should originate from the same common palmar digital artery. This technique offers a possibility to repair the defects of two adjacent fingers.  相似文献

Abstract:
Objective To explore the effect of using proper digital artery lateral cutaneous branch-chain flap with dorsal digital nerves or dorsal branch of proper digital nerye for repairing of fingertip defect.Methods From December 2008 to November 2009, 24 cases (26 digits) of fingertip defect were treated with proper digital artery lateral cutaneous branch-chain flap.The flap was designed on the lateral side of the proximal phalanx of the injured finger with its long axis running on the lateral midline of the finger.The vascular pedicle was 0.8 to 1.0 cm wide.The pivot point was at the distal 1/3 of the middle phalanx upon which the flap was reversed to repair the defect of the fingertip.The dorsal digital nerve or dorsal branch of proper digital nerve was included in the flap and coapted with the nerve in the wound to reconstruct sensation of the injured finger.Results All 26 flaps survived.Postoperative follow-up period was 6 to 8 months.All these flaps recovered with satisfying and quality, excellent sensation with 4 to 8 mm two-point discrimination.ROM of the interphalangeal joint of the injured finger was good.Conclusion Proper digital artery lateral cutaneous branchchain flap transfer with nerve coaptation is an ideal method for repairing fingertip defect.The surgery is simple.Reliable blood supply can be achieved without sacrificing the proper digital artery.Coaptation of the nerve restores sensation at the fingertip.There is minor donor site damage and very few complications.  相似文献

We report the results of pulp reconstruction with a new heterodigital reverse flow island flap. A dorsolateral flap from the middle phalanx, based on the digital artery is raised from the adjacent uninjured finger. The common digital artery, between the injured finger and the donor finger, is ligated and transected just before its bifurcation. The two converging branches of the digital arteries can be entirely mobilized as a continuous vascular pedicle for the flap. Thus the vascularization is now supplied by reverse flow through the proximal transverse digital palmar arch of the injured finger. To provide sensation the dorsal branch of the proper digital nerve from the donor finger can be included in the flap. Six reverse heterodigital island flaps were used in patients. In five patients the flap was used for pulp reconstruction and in one case for covering a dorsal digital defect. In one case mild venous congestion occurred. Good skin coverage with supple and well-vascularized skin was obtained in each patient. The static two-point discrimination over the flap was between 6 and 15 mm. This new procedure is indicated for extensive pulp defects in fingers in which reconstruction cannot be done using other flaps and as an alternative to microsurgical reconstruction.  相似文献

Background:

Fingertip defect can be treated with many flaps such as random pattern abdominal flap, retrograde digital artery island flap, V-Y advancement flap, etc. However, swelling in the fingertip, dysfunction of sensation, flexion and extension contracture or injury in the hemi-artery of the finger usually occurs during the recovery phase. Recently, digital artery perforator flaps have been used for fingertip reconstructions. With the development of super microsurgery techniques, free flaps can be more effective for sensory recovery and durability of the fingertip.

Materials and Methods:

Six cases (six fingers) of fingertip defects were treated with free digital artery perforator flaps of appropriate size and shape from the proximal phalanx. During surgery, the superficial veins at the edge of flap were used as reflux vessels and the branches of the intrinsic nerve and dorsal digital nerve toward the flap were used as sensory nerves. The proximal segment of the digital artery (cutaneous branches) towards the flap was cut off to form the pedicled free flap. The fingertips were reconstructed with the free flap by anastomosing the cutaneous branches of digital artery in the flap with the distal branch or trunk of the digital artery, the flap nerve with the nerve stump and the veins of the flap with the digital artery accompanying veins or the superficial veins in the recipient site.

Results:

Six flaps survived with successful skin grafting. Patients were followed up for 6-9 months. The appearance and texture of the flaps was satisfactory. The feeling within the six fingers recovered to S4 level (BMRC scale) and the two point discrimination was 3-8 mm.

Conclusion:

Free digital artery perforator flap is suitable for repairing fingertip defect, with good texture, fine fingertip sensation and without sacrificing the branch of the digital artery or nerve.  相似文献

The dorsal digital and metacarpal island flaps have been described for use in a variety of clinical situations. On the basis of the authors' previous angiographic studies, these two skin flaps were planned on the dorsum of the proximal phalanx or intermetacarpal space based on the vascular anastomoses between the proximal dorsal cutaneous branches of the palmar digital artery and the dorsal digital branches of the dorsal metacarpal artery at the level of the proximal phalanx. The authors present a series of 13 patients using these flaps. To reconstruct the injured finger pulp, the reverse dorsal digital flap was used in 5 patients, and the reverse dorsal metacarpal flap was used in 8 patients. Most of the 13 patients sustained a work-related injury. Associated injuries of bone, joint, or tendon occurred in most patients. In all patients, the skin defect was located distal to the proximal interphalangeal joint. The skin paddle was taken from the dorsal aspect of the middle and ring fingers or the first, second, third, and fourth metacarpal area. All flaps survived completely. Two patients who had the dorsal branch of the sensitive radial nerve anastomosed to the digital nerve recovered 6-mm two-point discrimination in the reverse dorsal digital flap. The results of this anatomic study and the authors' clinical experience confirm the reliability of the dorsal digital and metacarpal island flaps.  相似文献

Fingertip or pulp loss of the fingers is observed frequently in unskilled workers. To reconstruct a sensate fingertip or pulp we designed the innervated reverse island flap based on the end dorsal branch of the digital artery, which was harvested from the dorsum of the middle phalanx. The sensation of the fingertip or pulp was re-established through coaptation of the proper branches of the digital dorsal nerves to the digital nerves. Three fingertip or pulp defects were reconstructed with this technique. All patients achieved satisfactory functional and cosmetic results. The mean follow-up time was 7.7 months. The average size of the flaps was 1.6 x 1.8 cm. The average static 2-point discrimination and moving 2-point discrimination of the flaps were 4.6 mm and 3.0 mm, respectively. The technique we applied seems to be an excellent option for 1-stage reconstruction of fingertip or pulp defects.  相似文献

The following case report illustrates the successful use of the reverse digital artery island flap in elderly patients. The reverse digital artery island flap is a recognised method of providing good quality soft tissue cover to the amputated fingertip. First described in 1986 by Kojima, Lai and Han have reported their experience of 52 and 120 of these flaps, respectively. The majority of patients in the literature are less than 50 years old, with ages ranging from 3 to 62 years. The flap is based upon reversed flow in the digital artery via a communicating branch from the contralateral artery at a point 5mm proximal to the distal interphalangeal joint crease. In the two cases reported below, we have shown that the indications for this type of homodigital flap reconstruction for fingertip amputations can be safely extended to elderly patients.  相似文献

Innervated dorsal adipofascial turnover flap for fingertip amputations   总被引:4,自引:0,他引:4  
Traumatic or thermal injury to the fingertip may result in composite tissue loss. Exposed tendon, bone, or joint surface is best treated by flap coverage. The authors present their experience with a new technique that provides coverage for fingertip defects using the innervated dorsal adipofascial turnover flap, which consists of adipofascial tissue only and relies on the arterial anastomotic network of this tissue layer to sustain its vascularization. Eight digital amputations between the distal phalanx proximal to the nail matrix and midportion of the middle phalanx were resurfaced successfully with the innervated dorsal adipofascial turnover flap. The flaps survived completely; the mean follow-up was 9 months. This technique seems to be a relatively simple way of achieving early recovery. It does not require the use of distant flap immobilization of adjacent digits, nor does it require the use of homodigital flaps, which may jeopardize an already injured finger. The main advantages of the innervated dorsal adipofascial turnover flap are its ready availability from the local tissue, its sensation, and the absence of functional and aesthetic disturbance at the donor site.  相似文献

Three patients underwent finger reconstruction using free dorsal middle phalangeal finger flaps (DMF flaps). All flaps survived. The free DMF flap relies on blood flow from the dorsal branches of the digital artery and is harvested from the skin on the dorsum of the middle phalanx. The digital artery gives rise to four dorsal branches; two in the middle and two in the proximal phalangeal regions. The flap is based on the dorsal branch of the digital artery that passes near the center of the phalanx. The characteristic feature of the free DMF flap is that the dorsal cutaneous veins are used as drainage vessels. Unlike island flaps, blood congestion does not occur after free DMF flap surgery. Sensibility of the free flap may be obtained by inclusion of the dorsal branches of the digital nerves in the flap pedicle. Loss of the digital artery at the donor site can be circumvented with venous grafting. Surgery under brachial plexus block is an advantage of this flap. The free DMF flap is a useful technique for skin and soft-tissue defects.  相似文献
