It is ensheathed by the [[synovial membrane]], and varies greatly in strength in different subjects; occasionally only the [[synovial fold]] exists, and in rare cases even this is absent. The ligament is made tense when the [[thigh]] is semiflexed and the limb then [[abducted (kinesiology)|abducted]] or rotated outward; it is, on the other hand, relaxed when the limb is [[adducted]]. It has, however, but little influence as a [[ligament]] past childhood<ref>[http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=2124003&dopt=Abstract Tan CK, Wong WC, Singapore Medical Journal], "Absence of the ligament of head of femur in the human hip joint", 1990 Aug; 31(4):360-3.</ref><ref>Gray's Anatomy</ref> according to some references.
