[Synovial cysts of the hip joint]

Abstract

Four cases of a ganglion of the hip joint are reported. Besides the symptomatology and the clinical findings, special attention is payed to the anatomical relationship. The weak part of the joint capsula medially to the longitudinal traction of the ligamentum iliofemorale and laterally to the ligamentum pubofemorale was found to be the source of these ganglions. The most helpful diagnostic measure is arthrography through a lateral access. Therapy consists of resection of the cystic tumor, and careful closure of the hip joint capsula will prevent recurrence.
