Table 3. Postulated functions of the ligamentum teres.

Mechanical	1. Stability • Rich in collagen and fibrous stiffness comparable to cruciate ligaments of the knee Able to show adaptive changes in response to external stress 2. Proprioception and fine-coordination • Nerve bundles present in all specimens, likely including somatosensory afferents contributing to the secondary joint protection system
Biological	1. Vascular supply • Blood vessels of varying sizes scattered throughout structure Layer of encircling fat around small arteries providing structural support to maintain lumen patency 2. Nociception • Nerve bundles present in all specimens, likely including pain fibers contributing to hip pain in ligamentum tears or ruptures
