Subcapital fractures of the four ulnar metacarpal bones

Several methods of reduction and fixation of subcapital fractures of the four ulnar metacarpals have been suggested. All current methods deal with the volar angulation of the fracture; but in 133 consecutive cases angulation in this direction was of little clinical consequence. The more serious sequelae must be ascribed either to rotary deformity or to ulnar angulation at the fracture-site. These deformities were usually the result of bad bandaging technique and not due to the initial trauma. A new principle of conservative treatment is suggested.
