“…Corresponding findings have been demonstrated in the dorsal wrist and scapholunate interosseous ligaments [14][15][16][17]44], where these ligaments had ample innervation compared with volar ligaments. Our histologic observations also add support to the theory that the DRL is a primary stabilizer of CMC-1 [2,3,5,42,45]. In concordance with studies made on the scapholunate interosseous ligament [13], we support the idea that intact proprioceptive mechanisms, requiring the presence of functioning mechanoreceptors and ligamentomuscular reflexes, will preclude posttraumatic OA evolvement.…”

“…The DRL has previously been described as the most important ligament stabilizing CMC-1 [2,3,5,42,45] but ours is the first study to analyze this ligament from a proprioceptive and histological point of view. We conclude that the DRL is a ligament with greater innervation and thus a more significant proprioceptive role in stabilizing the CMC-1 as compared with the AOL in patients with CMC-1 OA.…”

Background The complex configuration of the thumb carpometacarpal (CMC-1) joint relies on musculotendinous and ligamentous support for precise circumduction. Ligament innervation contributes to joint stability and proprioception. Evidence suggests abnormal ligament innervation is associated with osteoarthritis (OA) in large joints; however, little is known about CMC-1 ligament innervation characteristics in patients with OA. We studied the dorsal radial ligament (DRL) and the anterior oblique ligament (AOL), ligaments with a reported divergent presence of mechanoreceptors in nonosteoarthritic joints. Questions/purposes This study's purposes were (1) to examine the ultrastructural architecture of CMC-1 ligaments in surgical patients with OA; (2) to describe innervation, specifically looking at mechanoreceptors, of these ligaments using immunohistochemical techniques and compare the AOL and DRL in terms of innervation; and (3) to determine whether there is a correlation between age and mechanoreceptor density. Methods The AOL and DRL were harvested from 11 patients with OA during trapeziectomy (10 women, one man; mean age, 67 years). The 22 ligaments were sectioned in paraffin and analyzed using immunoflourescent triple staining microscopy. Results In contrast to the organized collagen bundles of the DRL, the AOL appeared to be composed of disorganized connective tissue with few collagen fibers and little innervation. Mechanoreceptors were identified in CMC-1 ligaments of all patients with OA. The DRL was significantly more innervated than the AOL. There was no significant correlation between innervation of the DRL and AOL and patient age. Conclusions The dense collagen structure and rich innervation of the DRL in patients with OA suggest that the DRL has an important proprioceptive and stabilizing role. Clinical Relevance Ligament innervation may correlate with proprioceptive and neuromuscular changes in OA pathophysiology and consequently support further investigation of innervation in disease prevention and treatment strategies.

“…43 A complete rotatory subluxation of the scaphoid was never observed when only the SL interosseous ligament was sectioned. Besides, static SL instability is noticed solely after a concomitant failure of the distal scaphotrapezio-trapezoidal ligament 44,45 or the dorsal intercarpal ligament. 46 Scapholunate dissociation is the most common instability pattern of the wrist and can, if untreated, lead to degenerative arthritis of the radiocarpal and, subsequently, of the midcarpal joint.…”

“…There is a ligament system around the TMC joint, which is made up of sixteen ligaments, mostly on the palmar side, that work to stabilize the TMC joint (Bettinger et al, 2000). Out of these ligaments, only the dorsoradial ligament is able to avoid joint subluxation toward the dorsal-radial direction, which might explain why the 1st metacarpal bone exhibited a greater displacement toward the dorsal side during the AA and CIR motions.…”
