Quiste sinovial de la cadera provocando ciatica. A proposito de un caso

Abstract

The term sciatica describes pain in the lower back and hip that radiates down the back of the thigh into the leg. It is very common and carries a lifetime incidence of 13%-40%. The prolapse of the intervertebral disc is the most common cause of sciatica. Other less frequent causes of sciatica are pelvic fractures, pelvic tumors, piriformis syndrome or sacroiliitis. Acetabular synovial cysts are common. They may be asymptomatic or cause pain and restriction at the hip joint. On rare occasions they can cause compression of local neurovascular structures such as the femoral vein and the femoral, obturator and sciatic nerves. We report the case of a 31-year-old woman with symptoms of left sciatica caused by a synovial cyst located on the posterior aspect of the hip joint.
