Abstract

PURPOSE
An anatomical study concerning the location of the perforators to the posteromedial thigh perforator flap was done for the purpose of clinical application, and reconstruction using this flap was undergone for 3 patients with ischial sores. METHODS: The authors dissected 6 cadavers, measuring the distance between the perforator of the posteromedial thigh perforator flap and the extended line of the inguinal crease. The location of the perforator was studied using this data. In the 3 cases mentioned above, perforators were traced using Doppler ultrasonography and the sores were reconstructed with posteromedial thigh perforator flaps. Anatomical study results showed that posteromedial thigh perforators were found 77+/-18.9mm below the extended line of the inguinal crease. Application of the flap in the 3 patients was successful.
CONCLUSION
The perforator to the posteromedial thigh perforator flap was found to be located in a relatively consistent position. Since this flap is also comparatively easy to elevate and mobilize, and shows low donor site morbidity, it is considered to be very useful in the treatment of ischial sores.
