The '''ligament of the head of the femur''', also known as the '''ligamentum capitis femoris''' or the '''ligamentum teres femoris''', is a triangular, somewhat flattened band implanted by its apex into the antero-superior part of the [[fovea capitis femoris]]; its base is attached by two bands, one into either side of the [[acetabular notch]], and between these bony attachments it blends with the [[transverse ligament]].
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. According to the Encyclopedia Britannica, the ligament gives the femur a stabilizing strength which, as in the orangatan, some animals lack<ref>[http://p2.www.britannica.com/eb/article-9033963/femur#215708.hook Femur article], Encyclopedia Britannica.</ref>.
