Bilateral side finger transposition flaps in the treatment of chronic postburn flexion contractures of the fingers

The authors present a surgical method of releasing postburn flexion contracture of the finger by two separate transverse incisions and covering the skin defects by transposing two random-pattern flaps from both sides of the finger. One of the proximally based flaps was transposed from one side of the proximal phalanx and the other flap was transposed from the opposite side of the middle phalanx. Because the flaps were raised from different sides of different phalanxes, the donor sites were closed primarily. A total of 37 fingers (14 hands, 11 patients) were treated with this method. The patients were all men aged 20 to 24 years old. The mean follow-up period was 9 months. The lack of extension of the proximal interphalangeal joints of the fingers was improved by approximately 45 deg using the described method. The authors conclude that this method can be used effectively in the treatment of mild to moderate postburn flexion contractures of the fingers.

End-of-Skin Grafts in Syndactyly Release: Description of a New Flap for Web Space Resurfacing and Primary Closure of Finger Defects

Treatment of syndactyly necessitates creation of neo-web space and separation of fingers. Traditionally, this has been done by use of flaps taken from the dorsum; the resultant raw areas thus created have been managed by use of skin grafts. The classical teaching has been that the separated fingers will need skin graft as primary closure is not possible. The skin grafts have a tendency to contract and lead to finger flexion contractures and “creep” of the web space. We describe a flap based upon subcutaneous tissue in the web that is moved in a V–Y fashion to resurface the neo-web. The flap donor site can easily be closed primarily. The fingers are then separated; the subcutaneous fat is carefully removed from the finger flaps under magnification to allow primary closure of the finger defects. It has been possible to primarily close the donor site and fingers in all the patients. The procedure has been used in seven patients with 14 web releases. The age varied between 10 months to 3 years. The V–Y advancement flap based upon the subcutaneous pedicle in the region of the web allows adequate creation of a new web space. The careful de-fattening of skin flaps allows the separated fingers to be closed primarily.

Use of the bilobed flap for coverage of exposed structures on the fingers.

An original surgical procedure for the repair of soft tissue defects localized on the dorsal aspect of the proximal phalanx of the fingers is described. A patient was seen with a posttraumatic soft tissue loss corresponding to the dorsal aspect of the second metacarpophalangeal joint and the adjacent proximal half of the proximal phalanx of the index finger with extensor tendon exposure. The repair of the defect using a local flap taken from the second web space and the dorsum of the proximal phalanx of the long finger provided excellent coverage with early movement and a good functional result.

Reversed dorsal digital and metacarpal island flaps supplied by the dorsal cutaneous branches of the palmar digital artery

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.

Lateral chest wall fasciocutaneous flaps in the management of burn contractures on the dorsum of the hand

Summary Post-burn contracture involving the dorsum of the hand with hyperextension and volar subluxation of the metacarpophalangeal joints of the fingers plus adduction contracture of the thumb is a crippling disability. Adequate release of such contractures leaves raw areas on the dorsum of the hand, forgers and in the first web space. Fasciocutaneous flaps from the contralateral chest wall (the lateral thoracic flap and the subaxillary flap) have been used in eight patients. The comfortable fixation position, the non-hairy nature of the flaps, the excellent vascularity and a concealed donor site, which can often be primarily closed, make these flaps attractive for the defects. Within a follow-up period of five to twelve months, all the patients returned to their previous vocation.

The proximal dorsal digital flap

In 9 patients, 10 flaps based on the dorsal branches of the digital artery from the dorsum of the proximal phalanx were used to cover tissue defects on the volar aspect of the fingers. Full-thickness skin grafts were applied to the donor defects. All flaps survived completely with no donor site morbidity. This flap appears to be an easy and reliable way of covering the flexor tendon, the digital nerve and the digital artery after contracture release or for skin defects on the volar surface of the proximal phalanx.

Double reverse-flow island flaps for two adjacent finger tissue defect

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.     

The second dorsal metacarpal artery neurovascular island flap

Eleven patients have had second dorsal metacarpal sensate island flaps used to cover local skin defects in the hand. The arterial supply is reliable but if the flap is extended beyond the proximal interphalangeal joint, distal flap necrosis or donor site difficulties may occur. Possible applications for this flap are demonstrated and some untried variations to increase its range are suggested. Its main use appears to be in the release of first web contractures and for resurfacing radio-palmar and thumb defects.     

Free digital artery flap: an ideal flap for large finger defects in situations where local flaps are precluded

The heterodigital arterialized flap is increasingly accepted as a flap of choice for reconstruction of large finger wounds. However, in situations where the adjacent fingers sustained concomitant injuries, the use of this flap as a local flap is precluded. This paper describes our experience with the free digital artery flap as an evolution of the heterodigital arterialized flap. Four patients with large finger wounds were reconstructed with free digital artery flap. Our indications for digital artery free flap were concomitant injuries to adjacent fingers that precluded their use as donor sites. The arterial supply of the flap was from the digital artery and the venous drainage was from the dominant dorsal vein of the finger. The flap was harvested from the ulnar side of the finger. The digital nerve was left in situ to minimize donor morbidity. The donor site was covered with a full-thickness skin graft and secured with bolster dressings. Early intensive mobilization was implemented for all patients. All flaps survived. No venous congestion was noted and primary healing was achieved in all flaps. In addition to providing well-vascularized tissue for coverage of vital structures, the digital artery was also used as a flow-through flap for finger revascularization in one patient. Donor-site morbidity was minimal, with all fingers retaining protective pulp sensation and the distal and proximal interphalangeal joints retaining full ranges of motion. In conclusion, the free digital artery flap is a versatile flap that is ideal for coverage of large-sized finger defects in situations where local flaps are unavailable. Donor-site morbidity can be minimized by preservation of the digital nerve, firmly securing the skin graft with bolster dressings, and early mobilization of the donor finger.     

Combined medialis pedis and medial plantar fasciocutaneous flaps for coverage of soft tissue defects of multiple adjacent fingers

Soft tissue defects of adjacent multiple fingers covered by a single large flap require secondary separation of the flap into each finger. Such covering obstructs independent motion of injured fingers until the single large flap is separated. This report describes the technique of combined medialis pedis and medial plantar fasciocutaneous flaps for reconstructing soft tissue defects of multiple adjacent fingers. Three male patients (age range, 18–33 years) underwent soft tissue reconstructions of multiple adjacent fingers with combined flaps. Injuries involved three adjacent palmar fingers, two adjacent palmar fingers, and two adjacent dorsal fingers. Average sizes of the combined flaps were 4.2 × 4.0 cm for the medialis pedis flap and 3.0 × 1.8 cm for the medial plantar fasciocutaneous flap. All flaps survived without vascular complications, and donor sites healed uneventfully. All patients experienced excellent recovery of range of motion for the reconstructed fingers. In conclusion, combined flaps may offer an alternative for coverage of soft tissue defects that involve multiple adjacent fingers. © 2014 Wiley Periodicals, Inc. Microsurgery 34:454–458, 2014.

Use of free dorsoulnar perforator flap in the treatment of postburn contractures of the fingers

BACKGROUND: Burns of the hand cause not only the impairment of hand function but also cosmetic deformity. Cases with dysfunctional hands with severe contractures increase if rehabilitation of the acutely burned hand is not done properly. PURPOSE: We present the use of free dorsoulnar perforator flap in the treatment of postburn contractures as an alternative when local flaps cannot be used. METHODS: Free dorsoulnar perforator flap was used in the treatment of seven hands with postburn contracture. Five of them had multiple digital postburn flexion contractures. Combined use of cross-finger and side finger transposition flaps was preferred when the adjacent finger was suitable for being cross-finger flap donor. When the adjacent finger was not suitable for being cross-finger flap donor, the free dorsoulnar perforator flap was preferred. Two of the patients had postburn web contractures. Free dorsoulnar perforator flap was used to release the web and to form a new web commissure. CONCLUSION: The free dorsoulnar perforator flap could be a good alternative to cover the defects created with the hand contracture release.
