Bipedicle strap flaps for reconstruction of longitudinal dorsal finger defects: a review of 42 cases.

We report our experience with 42 bipedicle strap flaps in 42 fingers of 37 patients for the reconstruction of long longitudinal dorsal finger defects. Twelve cases were compound lesions with tendon lacerations. All flaps healed without infection, congestion or necrosis. At follow-up, mean total active interphalangeal joint mobility was 150° and 108° in patients without and with tendon lacerations, respectively. The median scores of the short version of the Disability of Arm, Shoulder and Hand questionnaire were 5 and 7, respectively. Patients were able to return to work or to their daily activities after a mean of 6 weeks. The patients were satisfied with the appearance in 34 of the 42 flaps. We conclude that the flap is a useful option for reconstructing dorsal digital lesions. It has a texture similar to the normal dorsal digital skin, and it is easy to perform without needing microsurgery.Level of evidence: IV.
