The axial bilobed flap for burn contractures of the axilla.

The axial bilobed flap, based on the transverse and descending branches of the circumflex scapular artery, was used to successfully reconstruct burn contractures of the axilla. The main advantages of this flap are that the donor site is closed primarily, it provides an adequate amount of healthy and pliable skin with an excellent blood supply and no chance of contraction, and it is an easy technique. In this paper, two cases are presented.

Use of the distally-based radial forearm flap supplied by the dorsal carpal arch, or palmar carpal arch, or both, in mutilating injuries. Two case report.

The distally-based radial forearm flap is safe, easy, and versatile as a regional, one-stage procedure to reconstruct soft tissue defects of the hand. However, there is a general perception that the deep and superficial palmar arches have to be intact to raise a distally-based radial forearm flap. We successfully used two flaps supplied by the dorsal carpal arch, or the palmar carpal arch, or both, despite the fact that the deep and the superficial palmar arches were damaged in mutilating injuries.

A modified reversed digital island flap incorporating the proper digital nerve.

A standard reversed digital artery flap is based on the digital artery and vena comitantes alone, leaving the proper digital nerve intact. In the authors' opinion, in situations in which the fingertip pulp is lost completely, it is unnecessary to leave the nerve in situ. Using their technique, the proper digital nerve is included in the pedicle. The pedicle is raised as a monobloc of fatty tissue containing the small veins important for drainage. The proper digital nerve in the flap is sutured to the stump of the opposite proper digital nerve. They found this flap to be very reliable, and quite easy and quick to raise. A patient is presented and discussed in detail.

Effect of surgical denervation on the viability of inferior epigastric neurovenous flaps in the rat.

The purpose of this study was to examine how the inferior epigastric neurovenous flap in the rat reacts to surgical denervation. The survival of a denervated flap was compared with that of an innervated flap. A 2 x 2-cm flap was raised in 30 female Wistar rats assigned randomly to six groups of 10 rats each: group 1, innervated neurovenous flap; group 2, denervated neurovenous flap, acute model; group 3, denervated neurovenous flap, chronic model; group 4, innervated inferior epigastric island flap; group 5, denervated inferior epigastric island flap, acute model; and group 6, control, composite graft. Acute denervation produced a significant decrease in the survival of the inferior epigastric neurovenous flap (p < 0.05). The surviving area of the innervated flaps decreased from 94+/-14% (mean +/- standard deviation) to 16+/-34% by acute denervation. Chronic denervation was effective in decreasing flap necrosis in these flaps (survival, 99+/-5%). There were no differences between the average viable area of the standard inferior epigastric flap in the denervated and innervated groups.

Preliminary report: the distally pedicled dorsoulnar forearm flap for hand reconstruction.

In this paper, a new flap for the coverage of soft tissue defects in the hand is described. To obtain a distally pedicled dorsoulnar flap, the dissection of the standard dorsoulnar flap is continued distally under the descending branch of the dorsal branch of the ulnar artery onto the dorsum of the wrist after the dorsal branch of the ulnar artery is ligated and divided. Our modification of the standard dorsoulnar flap converts this flap to a distally based flap, which provides a potentially longer pedicle and increases the arc of rotation of the flap. Two successful cases are reported.

Combined treatment of digital degloving injuries: a case report.

In a digital degloving injury of four fingers, a combined treatment of tripedicle dermal flap, free hemipulp web flap, and skin graft was used. The functional and cosmetic results of the hand were satisfactory. The patient had an excellent sensory recovery in the free hemipulp web flap and did not complain of any disability from the donor site.

Use of a subcutaneous pedicle ulnar flap to cover skin defects around the wrist.

A subcutaneous pedicle ulnar flap used to cover a skin defect around the wrist is reported. Unlike the standard ulnar flap, which is isolated around the dorsal branch of the ulnar artery and its associated veins, this flap is based on the ascending branch of the dorsal branch of the ulnar artery more proximally to obtain a longer vascular pedicle. A subcutaneous pedicle flap that contained the ascending branch, its associated veins, and a superficial vein was obtained. The disadvantages of the standard ulnar flap can be overcome by this design, which provides greater mobility, preserves the healthy skin between the rotation point and the defect, and eliminates contour abnormalities.

Combined use of axillary block and lateral femoral cutaneous nerve block in upper-extremity injuries requiring large skin grafts.

An axillary block and lateral femoral cutaneous nerve block combination was used in 11 patients with upper-extremity injuries requiring large skin grafts. In our experience, this block combination was highly successful. All but one of the patients obtained excellent pain relief (mean visual analog pain scores, 0.2) that required no narcotic analgesics or sedatives. There were no systemic or neurologic side effects attributed to the local anesthetic drugs. We believe that combining an axillary block and a lateral femoral cutaneous nerve block is a clinically useful and effective technique and an excellent anesthetic alternative for procedures requiring large grafts for the upper extremity.

Simultaneous soft-tissue reconstruction and revascularization of the thumb with a flow-through distally-pedicled radial forearm flap.

The authors report the application of the flow-through concept to a distally-pedicled radial forearm flap for simultaneous thumb revascularization and soft-tissue coverage. A distally-pedicled radial forearm flap was used to cover a skin defect at the base of thumb and thenar area. The flap artery (reversed radial artery) was anastomosed to the distal ends of the defective digital arteries. The flap survived completely, and the thumb was well-vascularized.

The distally based ulnar artery forearm flap supplied by the dorsal carpal arch.

It is accepted that the ulnar artery forearm flap is dependent on the integrity of the palmar arches for ulnar arterial backflow and the patency of both radial and ulnar arteries. A patient is presented who demonstrates the successful use of the ulnar artery forearm flap supplied by the dorsal carpal arch via the dorsal branch of the ulnar artery. In this patient, the ulnar artery was damaged distal to the dorsal branch of the ulnar artery. A distally based ulnar forearm was dissected up to the dorsal branch of the ulnar artery and pivoted around this branch. This flap survived completely with no postoperative problem.

U-I flap.

This article describes the principle, vascular basis, and applications of a new flap derived from the dorsal hand skin. The principle is a pedicle-lengthening procedure that is to revert a "U"-shaped vascular structure into an "I"-shaped vascular structure. By using this principle, a dorsal metacarpal flap, comprising the second dorsal metacarpal artery, the dorsal carpal arch, the dorsal branch of the radial artery, and the first dorsal metacarpal artery, was developed. In this flap, the skin territory was placed over the first dorsal metacarpal artery. The flap was rotated around a web space-connecting vessel between the second dorsal metacarpal artery and the palmar arterial system. We used this flap for resurfacing large defects beyond the proximal interphalangeal joint and degloved fingers in six cases. In two cases, the flap was used as an innervated flap. In one case, the flap was used as a tenocutaneous flap with a segment of the extensor indicis proprius tendon. We found this flap to be useful in selected circumstances.
