Abstract: A tissue microfracture apparatus including a housing having a proximal end and a distal end that includes an aperture. The apparatus also includes an elongated member having proximal and distal ends with at least one tissue microfracture spike protruding from the distal end. The member operates cooperatively with the housing to expose a portion of the spike through the aperture. The apparatus also includes a disposing facility between the elongated member and the housing to dispose the spike in a home position within the housing. The disposing facility may be a spring element positioned at either the proximal or distal end of the housing. The elongated member may include a force receiving surface on the proximal end for receiving a force that facilitates exposing the portion of the spike. An exposure limiting facility limits the exposed portion of the spike.

Abstract: Embodiments of the training brace assembly utilize an elastic training portion about a body portion to provide a resistance force to the limbs about the body portions. The elastic training portion may be positioned from attachment points on upper and lower mounting portions to provide the resistance force that influences the movement of the mounting portions and the body portion. In embodiments for a hip joint as the body portion, the training brace assembly provides a progressive resistance force that may assist in neuromuscular training of the hip joint.
