Biomechanics of the trapeziometacarpal joint.

The trapeziometacarpal joint is structured to allow simple angular and simultaneous angular or rotational movements of the first metacarpal. The geometry of the joint is partitioned as follows: a saddle-shaped area (the central area of the trapezium and metacarpal ridge), where simple angular movements occur, and a spherical region (the palmar area of the trapezial articular surface and metacarpal slopes), where simultaneous angular movements take place. Rotation of the first metacarpal during opposition (pronation) and retroposition (supination) depends on three factors: muscular activity, ligament tension, and congruence of the spherical portion of the trapeziometacarpal joint.

Congenital ulnar drift of the fingers. Pathogenesis, classification, and surgical management.

The classification of congenital ulnar drift is based on the tissues involved. Type I depends basically on malformation of the skin and retinaculum cutis. This is a fasciocutaneous deformity, corrected by simple release of the affected tissues followed by a free full-thickness skin graft. The deformity in Type II is more severe and the results of surgery are not as satisfactory as they are for Type I.
