Upper Extremity Defects Clinical Trial
Official title:
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 defects of the soft tissues of the hand and upper extremities are common and may be challenging to the reconstructive surgeon. Several reconstructive procedures have been described to manage these defects, including local, regional, distant, and free flaps. The aim of this study is to report the techniques, outcomes, and complications of pedicle abdominal flaps in reconstructing hand and upper extremity defects. We included patients with different traumatic defects in the hand and upper extremities who underwent reconstruction by random pedicle abdominal flaps between 2002 and 2017. Data was collected and analyzed, variables studied included; patient age and sex, etiology and size of the defect, complications, outcomes, and the need for further revision procedures. Potential factors affecting flap survival were examined using appropriate statistical analysis.
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.
