摘要:
An apparatus and related method for controlling a load on a human hip joint during normal gait while preserving motion. The approach is intended to treat osteoarthritis of the hip without substantially resisting an angular displacement associated with full mobility of the pelvis and femur bones.
摘要:
Various embodiments are directed to a sheath for covering one or more components of an extra-articular implantable mechanical energy absorbing system. The sheath is generally an elongated structure having an inner space extending the length thereof. In use, the sheath can exclude the energy absorbing system from surrounding tissue and facilitate creating a capsule for its operation. Materials and dimensions are selected to achieve these purposes. The ends of the sheath include various attachment mechanisms for securing the sheath to one or more components of an extra-articular implantable mechanical energy absorbing system.

Positioning instruments and related methods are described for implanting an energy absorbing system for treating joints. The positioning instruments and methods allow the energy absorbing system to be positioned at a joint such that the desired motion will occur for the particular design of a particular energy absorbing system which is to be implanted. The positioning instruments include a locating instrument for locating an anatomical feature and a target location for implantation of the energy absorbing system, a verification instrument for verification of the target location, a placement guide for guiding placement of a part of the energy absorbing system, and positioning device for aligning portions of the energy absorbing system.

A surgical implantation approach for preparing a patient and precisely and effectively placing an energy absorbing apparatus relative to the patient's anatomy. Various surgical implantation apparatus and methods for achieving proper device-to-anatomy juxtapositional relationships are employed in the implantation approach.

摘要:
Internal braces and methods of implanting same. A brace can be implanted on one side of a joint, or a pair of braces can be implanted, one on each opposite side of a joint. Each brace supports the joint over at least a portion of its range of motion. Distraction may be provided, or load sharing can be accomplished without distraction. Relative axial rotation of the bones connected by the brace may be permitted. One or more compliant members may be provided in the brace.
