Reverse second and third dorsal metacarpal artery fasciocutaneous flaps for repair of distal- and middle-segment finger soft tissue defects

The present study evaluated the clinical efficacy of reverse second and third dorsal metacarpal artery fasciocutaneous flaps for repair of distal- and middle-segment finger soft tissue defects. A total of 14 patients with distal- and middle-segment finger soft tissue defects complicated by exposure of the phalanx or tendon were repaired using second and third dorsal metacarpal artery fasciocutaneous flaps ranging between 2.0 cm × 4.5 cm and 3.0 cm × 7.0 cm. All of the skin flaps survived after surgery. Follow-up data during a 6- to 40-month period showed that the flaps exhibited a satisfactory appearance. They were not fat or clumsy, with a 2-point discrimination of 5 to 9 mm, and there was good recovery of finger function. The donor site was able to be directly sutured without dermoplasty. Pigmented linear surgical streaks appeared in the donor site. The second and third dorsal metacarpal artery fasciocutaneous flaps provide a good approach for the repair of distal- and middle-segment finger soft tissue defects and functional reconstruction because of convenient dissection, little trauma, sufficient use of the dorsal metacarpal artery, large harvested area of the flap, and a good dissection range.

Stepladder dorsal metacarpal flaps for dorsal finger and hand reconstruction.

The authors demonstrate successful cases of stepladder dorsal metacarpal V-Y advancement and rotation-advancement flaps for reconstructing defects on the dorsum of the finger and hand. One side of the flap is designed in a multilobed shape, and each lobed flap is designed on the dorsum of adjacent fingers. These flaps are supplied by dorsal metacarpal vessels. Consequently, this method has the elements of the stepped incision technique, in combination with the V-Y and rotation-advancement principle. All flaps survived completely. This technique may be a useful option for reconstruction of defects of the dorsum of the finger and hand.     

Sensate first dorsal metacarpal artery flap for resurfacing extensive pulp defects of the thumb

Finding an appropriate soft-tissue grafting material to close a wound located over the distal phalanx of the thumb, especially the pulp region, can be a difficult task. A sensate first dorsal metacarpal artery flap, mobilized from the dorsum of the adjacent index finger and used as an island pedicle skin flap, can be useful for this purpose. The pedicle includes the ulnar branch of the first dorsal metacarpal artery, the dorsal veins, and the cutaneous branch of the radial nerve. Although this tiny artery is anatomically variable, safe dissection can be achieved by including the radial shaft periosteum of the secondary metacarpal bone and the ulnar head fascia of the first interosseous muscle.This approach has been used for 8 individuals with extensive pulp defects of the thumb over the past 3 years. Skin defects in all patients were combined with bone, joint, or tendon exposure. All flaps survived completely. This 1-stage procedure is reliable and technically simple. It provides sensate coverage to the pulp of the thumb but also avoids nerve repair or more complicated microsurgery.

Abstract：

Objective To report operative procedures and clinical results of repairing finger soft tissue defects with a modified reversed island flap pedicled on a perforating branch of the dorsal metacarpal artery. Methods From January 2005 to March 2008,we repaired 38 finger soft tissue defects in 31 patients (26 men and 5 women) with a modified reversed island flap pedicled on a distal perforating branch of the dorsal metacarpal artery and anastomosis of the cutaneous nerve.Their ages ranged from 14 to 66 years,with a mean of 29.6 years.Altogether 11 index,18 middle,6 ring and 3 little fingers were injured.Nine patients were complicated with rupture of tendons,3 with extenso-tendon defects and 5 with middle phalanx fractures.The defect areas ranged from 1.0 cm × 0.8 cm to 3.2 cm× 2.5 cm.The flap areas ranged from 1.2 cm× 1.0 cm to 3.5 cm× 2.8 cm.The flap did not carry a full length of the dorsal metacarpal artery but only the distal perforating branch of the artery.The rotating point of the flap pedicle was altered from the dorsal to the palmar side to extend the vessel pedicle.The donor sites were closed by suture or skin graft. Results Twenty-eight patients (35 fingers) were followed up for 3 to 25 months (mean,15.3 months) .All flaps survived with satisfactory appearance,sensation and function.All flaps and donor sites obtained primary healing.The two-point discrimination was 6 to 9 mm (mean,7.7 mm).According to Total Active Movement (TAM) evaluation system,the results were excellent in 20,good in 13 and fair in 2 fingers,with a good to excellent rate of 94.3％. Conclusion The modified reversed island flap pedicled on a distal perforating branch of the dorsal metacarpal artery and anastomosis of the cutaneous nerve is an easy,safe and effective treatment for finger soft tissue defects.

Role of perivenous areolar tissue in the viability of venous flaps: an experimental study on the inferior epigastric venous flap of the rat.

This study was performed to investigate how the perivenous areolar tissue affects survival of the rat inferior epigastric venous flap model designed by Yuen and Leung (1991). Five groups of flaps were studied; group A--flap based on an inferior epigastric vein and areolar tissue; group B--flap with a skeletonised vein; group C--control, nonvascularised flap; group D--flap based on perivascular areolar tissue alone; group E--flap with a skeletonised artery and vein. Each group included 40 flaps; 20 of them had a silicone sheet placed under the flap, the other 20 did not. All flaps of group E survived. The success rate of group A with and without a silicone sheet was 60% and 90% respectively. All flaps of the other groups (B, C, D) necrosed. Histological examination of the pedicle showed that many minute vascular channels (single-cell-layered capillaries) were present apart from the inferior epigastric vein. This result confirms the importance of the perivenous areolar tissue in perfusion of the skin island, at least, in the inferior epigastric venous flap in the rat.
