Strategy for Reconstructing Multiple Pressure Sores in a Single Patient: A Case of Three Pressure Sores on One Pelvis

Abstract

Pressure sores are frequently observed in chronically bedridden patients. When body position is not changed regularly, a single ulcer may develop in the area subjected to constant pressure, such as the sacral or trochanteric region; one habitual position usually results in one sore. The simultaneous presence of pressure sores on the sacrum and both trochanteric regions in a single patient is uncommon, and their reconstruction is challenging. A 48-year-old male paraplegic patient with three pressure sores on the pelvis was referred. The sores involved the sacral and bilateral trochanteric regions and were complicated by infection, including osteomyelitis. Serial flap coverage was staged according to wound readiness and the resolution of infection. First, the right trochanteric sore was reconstructed using a perforator-based island flap (PBIF). After 9 days, the sacral sore was reconstructed with another PBIF. After an additional 20 days, the left trochanteric sore was covered using a pedicled anterolateral thigh musculocutaneous flap. All flaps were selected based on lesion size and condition and survived without major complications. When reconstructing multiple sores in one patient, establishing a clear strategy is essential. The order of reconstruction, appropriate intervals between procedures, and optimal flap selection are key considerations.
