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： A trial neck for hip surgery and a method of attaching a trial neck to a femoral canal preparation instrument. The trial neck includes a body portion including a bore for receiving a proximal end of a femoral canal preparation instrument. The trial neck also includes an elongate neck extending from the body portion. The trial neck further includes a locking mechanism comprising a lever. The lever has a first end integral with the body portion. The lever also has a second end. The lever further has an engagement surface located intermediate the first end and the second end. The second end of the lever is actuable to urge the engagement surface against the proximal end of the femoral canal preparation instrument to secure the proximal end of the femoral canal preparation instrument within the bore.

摘要： A surgical component, a kit including the surgical component, and a surgical method. The surgical component includes a body portion. The surgical component also includes an elongate stem for inserting into an intramedullary canal of a patient. The elongate stem extends distally from the body portion. The elongate stem has a longitudinal axis; a proximal end; a distal end; and a plurality of splines located on an outer surface of the stem. The splines are circumferentially arranged around the stem. At least some of the splines are tapered such that each tapered spline is narrower at a distal part of that spline than at a part of that spline that is proximal with respect to the distal part. The surgical component further includes an elongate neck portion extending from the body portion at a non-zero angle with respect to the longitudinal axis of the stem.
