Anatomical Basis of Dorsal Forearm Flap

Injection studies on 35 upper limbs with neoprene latex were carried out and the limbs carefully dissected to observe the vascular contribution of the posterior interosseous branches of the dorsal forearm, the transverse anastomosis between anterior and posterior interosseous vessels and the calibre of the vessel. The findings indicated that a fascia-cutaneous flap based on septocutaneous branches of the posterior interosseous artery can be raised as a reversed forearm for resurfacing after skin loss in the hand.

The skin of the dorsal aspect of the forearm is supplied by several cutaneous branches of the posterior interosseous artery. This vascular anatomy permits the surgeon to obtain an island flap of the dorsal forearm based on the distal anastomosis between the two interosseous arteries at the distal part of the interosseous space. This flap can reliably be transferred to different skin defects of the hand such as those created by correction of an adduction contracture of the first web space, or on the back or front of the wrist level. Its principal advantages are that it is a thin flap with excellent circulation and that it is possible to close the donor area primarily provided the island flap is not wider than 3 to 4cm. The procedure has been employed in 25 patients with satisfactory results.

Interosseous Artery

Background: Reverse-flow posterior interosseous artery (rPIA) flap is an excellent tool for restoration of defects in the hand and upper extremity, sparing the main arteries to the hand. Its reliability has been well established. Materials and Methods: Fifty-one cases of rPIA flap involving 49 patients were retrospectively reviewed. The inclusion criteria were age, sex, etiology, size and location of the defect, flap size, number of perforators included, pedicle length, flap inset, donor site coverage, complications, and ancillary procedures. Results: This study included 44 men and 5 women, ranging in age between 10 and 73 years. The subjects had soft tissue defects of the hand and upper extremity mainly due to traumatic injuries, including scar contractures of the first web space in 18 cases, thumb amputations in 6 cases, and congenital defects in 1 case. Among the 51 rPIA flap elevations, 3 cases involved flap failure due to the absence of proper pedicle. A fasciocutaneous pattern was observed in 45 cases and a myocutaneous pattern in 3 cases. In 5 cases of unplantable thumb amputations, the rPIA flap was performed for arterial inflow to the secondary toe-to-thumb transfer. Venous congestion of varying degrees was noted in 7 cases involving partial necrosis in 2 cases. During the mean 17 months of follow-up, patients were generally satisfied with the final outcomes. Conclusion: The rPIA flap can be used not only for soft tissue coverage of the hand and upper extremity but also as a recipient arterial pedicle for a secondary toe-to thumb transfer.
