Reconstruction of Hand and Upper Extremities Defects by Thin Random Pedicle Abdominal Flaps, Still a Valid Option in Developing Countries: A Cross Sectional Study

Traumatic soft tissue defects of the hand and upper extremity are common and may be challenging to the reconstructive surgeon, especially when they are severe and associated with exposed vital structures such as tendons, nerves, bones, and joints. Although these defects are rarely lethal; they are invariably resource demanding, and a source of significant long-term disability. Several reconstructive procedures have been described to cover hand and upper extremities soft tissue defects, including local, regional, distant, and free flaps. Traditionally, pedicle abdominal flaps, whether axial or randomly based, have been considered the standard for successful upper limb reconstruction.

With the introduction of microsurgery in the seventies of the last century, microsurgical free tissue transfers have become the gold standard for upper extremities functional reconstruction. Free flaps and other microsurgical techniques have been used to achieve early, functional, custom-tailored reconstructive solutions for upper limbs injuries. However, despite the superiority of free flaps, this option may not be always accessible especially in developing countries, owing to the high cost and technical demands. Moreover, they may be contraindicated in certain circumstances. In these situations, pedicle abdominal flaps may once again come into the light as an alternative option for safe and effective upper extremities reconstruction.

At Jordan University Hospital, with limited microsurgical facilities, the investigators have been using random pedicle abdominal flaps in patients with different traumatic hand and upper extremities defects. The aim of this retrospective study is to report the investigator's experience in using this technique, in regards to the indications, complications, outcomes, and evaluating factors affecting flap survival rate.
