Abstract: The present invention includes a method and devices for treating osteonecrosis in, e.g., children, adolescents, and adults comprising: identifying a subject in need of treatment for osteonecrosis; drilling two or more holes into a bone in need of treatment for osteonecrosis; inserting two or more needles or cannulas into the holes in the bone; washing an interior of the bone with a washing fluid introduced through one or more of the needles or cannulas inserted into the bone; and after washing the interior of the bone introducing one or more bone growth promoting materials or cells into the bone.

Abstract: A device to modulate growth of an immature rib comprising a spring plate configured to provide an elastic spring function in bending along its length; two rib hooks each configured to secure the spring plate to the immature rib; and a transverse hook or a pedicle screw configured to secure the spring plate to the vertebra.

Abstract: The present invention includes a hip-off-loading device including a pelvic assembly including a pelvic base plate configured for attachment to a human pelvis; a distraction adjustment mechanism coupled to the pelvic base plate, wherein the distraction adjustment mechanism is lockable, to provide for adjusting the distal distraction of the hip-off-loading device; and at least a portion of a rotation mechanism to provide for internal or external rotation or both, and to provide for non-dynamic interoperative adjustment of abduction, adduction, or both; a link movably coupled to the pelvic assembly to provide for internal or external rotation or both; and a femoral assembly coupled to the link and including a femoral attachment mechanism for attachment to a femur to provide for flexion, extension, or both.

Abstract: A device for repairing a tear in a portion of tissue comprises a proximal actuator portion, a transfer needle extending distally from the proximal actuator portion and a catch needle extending distally from the proximal actuator portion. A suture needle is disposed in the transfer needle, and is extendable from the transfer needle toward the catch needle and retractable from the catch needle toward the transfer needle. An extendable catch plunger is disposed in the catch needle for capturing suture therein when it is transferred from the transfer needle. A retractable insertion sheath is provided for covering the transfer needle and the catch needle when the device is inserted into a procedural site. A depth limiting apparatus limits the depth of insertion of the needle into the procedural site.
