摘要： A surgical instrument and method for assessing restoration of the femoral head centre is provided. The instrument comprising: a body having a first connector for attaching the body to a femoral part, and wherein the body defines a plurality of apertures therein, wherein each aperture corresponds to a respective femoral head centre arising from a respective corresponding femoral neck; and a gauge, wherein the gauge includes a pin at a first end and an arm extending transversely from the pin and wherein the pin is receivable in each of the plurality of apertures and the arm bears a scale indicating a distance from the pin. The approach seeks to provide a simple and/or easy to use approach to restoring the native femoral head position during a hip replacement surgical procedure.

摘要： The invention provides a surgical device for performing a controlled resection of the neck of a femur during a hip replacement procedure. The surgical device comprises a body portion having: a frame comprising an aperture dimension for receipt of a femoral head of the femur to position the body portion with respect to a centre of the femoral head; a resection guide for indicating a position of a resection plane on the femoral neck, and an arm extending between the frame and the resection guide. The body portion includes a linear alignment surface for alignment with a femoral shaft axis of the femur while the frame is mounted on the anterior or posterior aspect of the femoral head.

摘要： A trial neck for hip surgery and a method of attaching a trial neck to a bone canal preparation instrument. The trial neck includes a body portion having a bore for receiving a proximal end of the bone canal preparation instrument. The trial neck also includes an elongate neck part comprising a pair of arms extending from the body portion. The trial neck further includes a clamping mechanism comprising a live spring formed by the body portion and said pair of arms of the elongate neck part and an actuator, for moving the clamping mechanism between a clamping configuration and a non-clamping configuration. In the clamping configuration, the pair of arms of the elongate neck part are pinched together to cause an inner wall of the bore to urge against the bone canal preparation instrument to retain the proximal end of the bone canal preparation instrument within the bore.

摘要： The invention provides a surgical apparatus for performing a controlled resection of the neck of a femur during a hip replacement procedure, the surgical apparatus comprising: a body portion. The body portion comprises a frame that is mountable on a femoral head of the femur to position the body portion with respect to a centre of the femoral head. The body portion also includes a resection guide for indicating a position of a resection plane on the femoral neck, and an arm extending from the frame and including markings for reading off a femoral head offset. The apparatus also includes a connector for mounting the body portion on an intramedullary rod located in an intramedullary canal of the femur, and for slidably receiving the arm. The connector includes a pointer. The femoral head offset is indicated by reading the position of the pointer relative to the markings on the arm.
