Cutaneous branch of the obturator nerve Cutaneous branch of the obturator nerve Occasionally the communicating branch to the anterior cutaneous and saphenous branches of the femoral is continued down, as a cutaneous branch, to the thigh and leg, as the cutaneous branch of the obturator nerve. When this is so, it emerges from beneath the lower border of the Adductor longus, descends along the posterior margin of the sartorius to the medial side of the knee, where it pierces the deep fascia, communicates with the saphenous nerve, and is distributed to the skin of the tibial side of the leg as low down as its middle.
Absence of gluteal muscle Absence of gluteal muscle The congenital absence of the gluteal muscle was described in 1976, as occurring in a brother and sister with absence of gluteal muscles and with spina bifida occulta. It was thought to be caused by an autosomal recessive gene. Edgar "et al." (2012) reported the case of a 15-year-old white male with congenital absence of the "gluteus maximus" muscles associated with spina bifida occulta, learning disability, optic nerve hypoplasia, scoliosis, and central nervous system hamartomas. If gluteal muscles were absent the following actions would not be possible. The "gluteus maximus" extends the thigh at the hip
