Background:
The medial arm is an optimal potential donor site for treating skin defects around the elbow. However, whether a reliable pedicled perforator flap could be harvested from the medial arm remains unanswered. The purpose of this study was to report the technique and our results using the medial arm pedicled perforator flaps.
Methods:
A total of eight flaps in seven patients underwent the medial arm pedicled perforator flaps to treat skin defects around the elbow. The flap was pedicled on one perforator 1.3±0.3mm in diameter within 3cm above the medial epicondyle. The flap size varied between 10 and 20cm in length and between 6 and 10cm in width.
Results:
Of the eight flaps in seven patients, seven flaps survived uneventfully except that one suffered venous insufficiency. Six patients were followed up for 1 month to 2 years. One patient was lost to follow-up after 7 days. The wounds in all patients healed satisfactorily. No deep wound infection and wound dehiscence developed. No revision surgery was performed in the survived flaps.
Conclusions:
The survival of the medial arm pedicled perforator flap confirms the phenomenon of one perforator perfusing multiple perforator angiosomes in the medial arm, although this study has the retrospective clinical nature and limited number of the patients. The medial arm pedicled perforator flap is a useful tool to treat skin defects around the elbow.
