Purpose This study highlights the advantages and disadvantages of Anterolateral Thigh (ALT) free flap using the brachial artery as the recipient vessel in large posterior defects of the elbow with early mobilization. Methods Eight patients with a soft tissue defect on the posterior elbow underwent reconstruction with an ALT free flap. Average age and follow-up were 29.5 years (range, 18-43 years) and 54 months (range, 35-76 months), respectively. All defects were on the posterior side, and brachial arteries on the anterior side were used as the recipient artery in all cases. Four defects were created by tumor excision, four were exposed with hardware after fixation of distal humeral and/or proximal ulna fractures. The dimensions of defects were between 80 and 352 cm(2). Cases were evaluated according to function (ROM), complications, tissue quality anticipated from reconstruction and immobilization time after the reconstruction. Results All flaps except one survived and met the tissue quality anticipated from this reconstruction. In the bigger flaps, an apparent ugly scar at the donor site was the main problem. The flap on the posterior, and recipient artery on the anterior had no adverse effects on early motion of the elbow. Two cases with fractures had minimal restriction of elbow movement due to post-traumatic stiff elbow. There was one case of partial flap loss after myocardial infarction. After the patient was medically stable, the remaining distal defect was closed with a pedicled radial forearm flap. Conclusion ALT free flap has numerous advantages in covering defects at the posterior elbow such as being pliable, thin and durable skin, with a long and reliable pedicle reaching the brachial artery without causing any problem in early motion and surgical reconstruction can be easily completed in the supine position.
