The labrum and transverse acetabular ligament (TAL) are classically described as distinct anatomical structures with abundant mechanoreceptors free nerve fibers. They deepen the joint act natural barriers against dislocation, thus providing additional stability. We hypothesized that severe coxarthrosis leads to elimination of TAL mechanoreceptors. This study evaluated microscopic anatomy specifically investigated neurological status these structures.Labral specimens from 35 consecutive patients undergoing total hip arthroplasty were dissected into a 4 per hip. Formaldehyde-fixed for presence endings by neurofilament protein S-100 immunohistochemistry microscopy.Mechanoreceptors identified in labral (2.3/high power field) but not specimens, sharp delineation between tissues. In contrast, both showed good vascularity fibers within fibrous connective tissue (mean, 2.6 sensory fibers/ high field vs 3.1/high field, respectively).This demonstrated lacks However, suggest potential roles pain generators.
