Abstract

External fixation is a method useful for the immobilization of the wrist after injury. The biomechanics of the wrist are discussed together with the treatment of simple injuries with uniaxial frames. Complex injury patterns cause more extensive disruption of wrist kinematics and therefore require more complex external fixation configurations that restrict motion in more than one plane. Internal fixation can also be combined with external fixation to solve special fracture problems. Eight cases are presented in which external fixation was applied 4 weeks after internal fixation because of poor alignment following closed reduction. Thereafter all the fractures united. The complexity of fixation technique should match the complexity of the fracture problem.
