Abstract

PURPOSE
Trochanteric pressure sores management has been improved through the development of musculocutaneous flaps. But it has many drawbacks such as donor site morbidity and functional muscle sacrifice. With the introduction of perforator flap, it is possible to use in every location where musculocutaneous perforators are present. We have reconstructed trochanteric pressure sores using perforator-based flaps from the ascending branch of lateral circumflex femoral artery. METHODS: Between May of 2006 and April of 2008, we performed six cases of perforator-based flap from the ascending branch of lateral circumflex femoral artery for the coverage of trochanteric pressure sores. For identifying perforators, a line was drawn from the anterior superior iliac spine to the superolateral border of the patella as the vertical axis, from the pubis to the trochanteric prominence as the horizontal axis. In the lateral aspect of the intersection of these two axes, various flap were designed according to its defects. The flap was raised in the subcutaneous plane above the fascia and the pedicle was traced by doppler and identified. The pedicle was meticulously dissected not to injure the periadventitial tissues and transposed to the defect. The donor site was closed primarily.
RESULTS
The mean age of patients was 56.2 years. Four male and two female patients were studied. Five patients were paraplegic. The mean defect size was 6 x 4 cm. The largest flap dimension was 14 x 7 cm. Donor sites were closed primarily without any complications. All flaps survived completely without necrosis, hematoma or infection. There were no recurrence during the follow-up period.
CONCLUSION
Trochanteric pressure sores using perforator-based flap from the ascending branch of lateral circumflex femoral artery can be performed safely and it would be a reliable option for coverage of trochanteric pressure sores with minimal donor site morbidity.
