Description[edit | edit source]
The Ligamentum Teres, also known as ligamentum femoris capitis, is an intra-articular extrasynovial ligament that has acetabular and femoral attachments.[1]
Earlier research have described it as a vestigial structure due to its slack state during distraction and surgeons have promoted its excision during procedures such as reduction of dislocations in developmental dysplasia of the hip and surgical hip dislocations.[2][3]
On the other hand, more recent studies have suggested the ligamentum teres to have an important function in proprioception, nociception, and as a secondary stabilizer of the hip joint. [4][5][6]
