OBJECTIVE: To evaluate the correlation between the presence of a lunate medial facet and the incidence of ligament lesions of the wrist and arthrosis of the proximal pole of the hamate. This study was carried out on cadavers. METHODS: Arthroscopic evaluation and dissection were performed on cadaver wrists. RESULTS: There was a clear, statistically significant correlation between arthrosis of the proximal pole of the hamate and the presence of a medial facet on the lunate. CONCLUSION: Arthrosis of the proximal pole of the hamate is correlated with the presence of a type II lunate. Level of Evidence III, Study of nonconsecutive patients; without consistently applied reference ''gold'' standard.
