Abstract:
Many kinds of operations have been devised to treat Kienböck's disease with variable results. But no one have mentioned about the advantage of early motion in distraction to prevent the fibro-osseous ankylosis and carpal collapse. Two cases with Kienböck's disease were treated by the complete excision of the lunate and replacement of it with pronator quadratus muscle pedicled rectangular bone graft. Once these procedures were accomplished, the distraction-motion devices were used to maintain the joint surfaces separated at predetermined distances while kinematically normal joint motion was gradually restored. Although the experience is limited to two cases, the final results seem to be very promising.
