Elbow coverage by the descending superficial radial artery flap: a clinical series and literature review

Purpose Soft tissue coverage of the posterior aspect of the elbow requires thin and flexible flaps to adapt to movements without constraining them. The authors report a clinical series of reconstruction by the descending superficial radial artery (DSRA) flap, a proximal forearm perforator flap which use is rarely reported in the literature. Methods Seven patients with a mean age of 50 years (range 24–88 years) were treated for a posterior elbow defect using the DSRA flap with an adipofascial pedicle. The flap was tunneled to the defect in the subcutaneous tissue or raised using the racket-like technique to avoid any pedicle compression. Results The mean follow-up was 3.3 months (range 1–12 months). A partial necrosis of the skin paddle occurred in an 88-year-old patient. In the other cases, the flap evolution was straightforward. At the last follow-up, the appearance of the flaps was satisfactory in terms of color, texture, and thickness. No complications were observed at the donor site. Conclusion The DSRA flap with an adipofascial pedicle is a simple, reliable, and reproducible method for reconstruction of small to moderate-sized defect on the posterior aspect of the elbow. Its use is easier for defects on the posterolateral side, but it can reach the medial olecranon.
