Acetabular Canal .  Part 2 S.V. Arkhipov, Independent Researcher, Joensuu, Finland Abstract This article describes the space where the ligamentum capitis femoris (LCF) attaches and functions.  See also Part 1 and Part 3 . Topography of the Acetabular Canal The acetabular canal has two powerful walls. On the outside, it is the bone-cartilaginous mass of the femoral head, which separates the contents of the acetabular canal from the cervical part of the hip joint, surrounding muscles, fatty tissue and synovial bags. On the medial side, the acetabular canal is separated by the pelvic bone from the pelvic organs, fatty tissue, muscles, large vessels and nerves. Figure 1.

  Acetabular Canal .  Part 3 S.V. Arkhipov, Independent Researcher, Joensuu, Finland Abstract This article describes the space where the ligamentum capitis femoris (LCF) attaches and functions.  See also Part 1 and Part 2 .   The Significance of the Acetabular Canal The acetabular canal contains the main areas of attachment for the LCF (ligamentum capitis femoris). Its distal end attaches to the femoral head, while the proximal end connects to the fossa and notch of the acetabulum. The primary purpose of the acetabular canal is to ensure the normal functioning of the LCF. Normally, the LCF should not come into contact with the joint surfaces. Therefore, the length of the LCF should not exceed the diameter of the acetabular fossa, i.e., the diameter of the central section of the acetabular canal Its depth should be less than the thickness of the LCF. Figure 1. Lateral wall of the acetabular canal and LCF; the bottom of the acetabulum is removed (from 1908GrayH )...

  Acetabular Canal . Part 1 S.V. Arkhipov, Independent Researcher, Joensuu, Finland Abstract This article describes the space where the ligamentum capitis femoris (LCF) attaches and functions. See also Part 2 and Part 3 .  Elements of the Hip Joint In the hip joint, articulatio coxae , the acetabulum of the pelvic bone ( os coxae ) directly contacts the head of the femur ( caput femoris ). The acetabulum ( acetabulum ) is a spherical-shaped cavity located on the external surface of the pelvic bone ( os coxae ), at the junction of the ilium ( os ilium ), ischium ( os ischii ), and pubis ( os pubis ). The component of the acetabulum in the shape of a horseshoe, covered with hyaline cartilage, is called the lunate surface ( facies lunata ). The acetabular fossa ( fossa acetabuli ) and the acetabular notch ( incisura acetabuli ) do not have cartilage coverage. These form a cavity resembling the shape of a tennis racket with a curved plane. At the bottom of the acetabular fossa li...

An excerpt from the article by Morris H. Dislocations of the Thigh: their mode of occurrence as indicated by experiments, and the Anatomy of the Hip-joint (1877, pp. 161-170). The author noted that the ligamentum capitis femoris (LCF) is stretched during flexion, adduction, and external rotation. It was found that the LCF is always damaged in hip dislocations, is more often torn from the femur, and is rarely ruptured. Discussion of article see article 1877BrookeC .   DISLOCATIONS OF THE THIGH: THEIR MODE OF OCCURRENCE AS INDICATED BY EXPERIMENTS AND THE ANATOMY OF THE HIP-JOINT. BY HENRY MORRIS, M.A., M.B., F.R.C.S., ASSISTANT SURGEON TO, AND LECTURER ON ANATOY1 AT, THE MIDDLESEX HOSPITAL. Received January 9th-Read February 13th, 1877. RECENTLY, whilst making various dissections of the hip-joint, the usually accepted doctrine that dorsal and ischiatic dislocations of the femur occur when the thigh is in a position of adduction appeared to me as very improbable, on anatomi...
