The posterior thigh flap for defect coverage of ischial pressure sores – a critical single‐centre analysis

ABSTRACT The development of pressure sores is still not only an enormous economical but also a medical burden. Especially in the ischial region, the local defect coverage remains demanding as it is the main weight‐bearing area in wheelchair‐mobilised patients and is prone to high mobility. The purpose of our study was to report our long‐time experience with the reconstruction of ischial pressure ulcers with the medially based posterior thigh flap. A retrospective analysis of all primary pressure sores grade III–IV in the ischial area, which were covered with a medially based posterior thigh flap between January 2008 and December 2014, at our department was conducted. A total of 28 patients underwent defect coverage of an ischial pressure sore with the aforementioned flap. The subgroup with complications showed a statistically significant longer hospital stay. A statistically significant correlation between age and the coincidence of comorbidities could be seen. Older patients showed significantly higher grades of pressure sores. The medially based posterior thigh flap is a safe and reliable flap design. Complication rates are comparable to other flaps. Nevertheless, in case of complications, a significantly longer duration of hospitalisation has to be taken into account.
