Abstract

Apparatus and methods enhance bone formation. The methods and apparatus provide a mechanical load (60a, 60b) applied to the epiphysis (44, 45, 62) of a bone (24, 26, 64) associated with a joint (22). The magnitude of the mechanical load is oscillated and is applied periodically for a short durations of time. The applied mechanical force induces formation of trabecular (70) and cortical (68) bones. Embodiments of the apparatus include passively and actively actuated bands (28, 128, 228, 328) which are positioned around at least a portion of a joint and provide mechanical loading on the joint, for example, on the epiphysis of a bone and oriented traverse (54, 76) to the longitudinal axis (56, 78) of the bone.
