Abstract
An artificial ligament assembly for spinal stabilization includes an outer hollow elastic longitudinal member, a rigid inner member, a bone anchor mechanism, a bone anchor, and a buffered space. The artificial ligament assembly further includes a clamp that controls a torsional motion of the outer hollow elastic longitudinal member with respect to the bone anchor mechanism. The outer hollow elastic longitudinal member is at least as long as the inner rigid member. The rigid inner member is configured in a substantially same shape as the outer hollow elastic longitudinal member. The bone anchor mechanism is coupled to the outer hollow elastic longitudinal member. The bone anchor connector may further include an insert end. The bone anchor is coupled to the bone anchor mechanism. The buffered space allows any of a compression and an extension of the bone anchor mechanism inside the outer hollow elastic longitudinal member.
