A retrospective review of 304 consecutive microvascular free flaps to the lower extremity was done to identify the patterns of usage, results, and problems. The most common indication (91%) was for the replacement of extensive tissue loss caused by motor-vehicle injuries. Most of the defects were below the mid-tibia (73%). ⋯ Fourteen patients (6%) underwent an amputation within the first 3 months, ten of them because of flap failure. Of 85 patients followed up for over one year, 91% had recovered good to excellent leg function. The ability to add healthy and well vascularized tissue to the traumatized limb is critical for the achievement of: 1) early definitive wound healing and restoration of function; 2) salvage of many impending amputations; 3) better prosthetic stump reconstructions; 4) better esthetic results.

Fifteen adult patients with clavicular nonunions were evaluated over a 10-year period. Fourteen of these patients were treated initially with a "figure-of-eight" clavicle strap. Seven presented with narrowing of the costoclavicular space, and symptoms of intermittent brachial plexus impingement or thoracic outlet syndrome. ⋯ We have found transcortical fixation by locking Knowles pins to be effective for treating hypertrophic nonunions, as well as for unreducible acute fractures. Atrophic nonunions require plate fixation and autologous grafting. Nonunion of the clavicle has been among the most responsive of nonunions in our experience, since all fractures treated by adequate reduction and fixation healed promptly.(ABSTRACT TRUNCATED AT 250 WORDS)
