[Tendon transfers for the upper extremity in cerebral palsy].

Upper extremity deformities in cerebral palsy are caused by the imbalance between spastic and weak muscles acting on unstable joints. The basic goals of surgical treatment of spastic hands and upper extremities of patients with cerebral palsy can be summarized as reducing the strength of spastic muscles, strengthening the antagonist muscles, and permanent stabilization of unstable joints. Surgical techniques to achieve these goals include lengthening of spastic muscles, tendon transfers, release or plication of the joint capsule, joint arthrodesis, neurectomies, and skin procedures. Amongst these surgical treatment options, this article will present, in more detail, tendon transfers which are performed especially to achieve balance and restore motor functions.
