Observations on the Joints of the Hand

Abstract
Thirty-two hands (sixty-eighty years) were dissected to study configuration and spatial setting of the articular surfaces of the joints of the thumb in order to note the features which are associated with deviation, torsion and rotatory movements. Four varieties of the trapezial surface were encountered in the carpometacarpal joint: saddle-shaped, triangular, ovoid and semicylindrical. The last exhibited marked osteoarthrosis with formation of osteophytes.
