Fragments of the article Sanders S, Tejwani N, Egol KA. Traumatic Hip Dislocation (2010). This review discusses the pathological anatomy of hip dislocation and describes the variants of traumatic changes in the ligamentum capitis femoris (LCF).
Quote 1.
A small contribution to the head comes from the foveal artery via the
ligamentum teres.
Quote 2.
With hip dislocations, the capsule and the ligamentum teres are usually
disrupted.
Quote 3.
Avulsed fragments of bone are frequently found attached to the
ligamentum teres and lying in the fovea.
Quote 4.
In posterior dislocations, the piriformis, gluteus maximus, capsule,
ligamentum teres, labrum, or a bone fragment may prevent reduction
(1979CanaleSF_ManugianAH).
Quote 5.
This finding is common and usually represents a small piece of bone
avulsed from the femoral head by the ligamentum teres.
