Abstract
51 wrists of 30 embalmed cadavers have been used to perform an anatomical and radiological study relating cartilaginous and ligamentous lesions of the wrist with sex, age, ulnar variance (UV) and the state of the triangular fibrocartilage complex (TFCC) in an elderly population (mean 76.6 years). Two-thirds of all wrists (66%) showed cartilaginous lesions, mainly on the lunate (22, or 44%). The TFCC was perforated in 23 wrists (46%), and most were central degenerative perforations. Correlations were found between ulnar variance and TFCC thickness (P<0.05) and ulnar variance and TFCC perforations (P<0.05). A significant relation was observed between age and proximal row intercarpal ligamentous ruptures (P<0.05) and between age and ulnar variance (P<0.05). No statistical correlation was seen between ulnar variance and cartilaginous lesions on the lunate (P<0.05) in this slightly ulnar negative population (mean–0.37 mm).
