Abstract
We read with great interest the article of Lin et al on the reconstruction of ischial pressure sores with the laterally based posterior thigh flap (PTF).[1] Despite the ongoing progress of pressure sore prevention and treatment, this problem remains difficult to solve. The ischium is the most frequent site of pressure sore occurrence, due in part to increased pressure exerted on the region during sitting and in part to motion over the ischial area.[2] Recurrence rates after pressure sore reconstruction (>50% in the long term) have remained largely unchanged during the past 40 years. Therefore, a rationale for flap coverage designed to treat a patient during the long term is necessary from the time of initial evaluation.[2] Despite high rates of flap survival, not all flaps are equally reliable in achieving coverage of the debrided pressure sore wound. Therefore, the most important step for early treatment success is appropriate flap selection, leaving the other possible options for repair undamaged.[2]
