Abstract
Between 1985 and 1995, 72 free lateral arm flaps (LAFs) were transferred in 68 patients. The main purpose of the reported study was to demonstrate a comprehensive follow-up and essential technical refinements extension of the flap, shaping of a custom-designed flap, the “emergency” free flap, and sensible nerve coaptation. The effect of nerve coaptation vs. no nerve adaptation was investigated by measuring objective and subjective grades of sensibility at the recipient site. The outcomes of sensory flap reinnervation showed no significant advantages of one over the other technique. The second intention was to clarify discrepant anatomic descriptions concerning the nomenclature of the supplying blood vessels. Current anatomic Investigations revealed that the main blood supply derives from the posterior radial collateral artery (anastomosing with the interosseous recurrent artery); blood supply via the anterior radial recurrent artery (anastomosing with the radial recurrent artery) has a secondary importance.
