title: The gluteus maximus muscle: experimental and clinical considerations relevant to reconstruction in ambulatory patients.
abstract: The gluteus maximus muscle and other haemodynamically related structures have been used for the reconstruction of significant defects in the perineum, sacrum, lumbar area and hip in 35 patients. The preservation of muscle function was achieved in all of 20 ambulatory patients and documented by gait analysis, muscle strength testing and EMG studies. Dye injection studies of the first perforating artery, inferior gluteal artery and superior gluteal artery led to the design of new flaps based on this arterial system. They include: medial advancements with extension above the sacrum, lateral advancements, lower gluteus advancements, the tensor fasciae latae gluteal extension and modifications of the gluteal thigh flap. These findings significantly increase our ability to close difficult wounds within the perineal, sacral, lumbar and trochanteric regions.
