The shaft flush channel is connected to the outside of the implant shaft via shaft flush holes (13, 13′; 112; 113) for discharging the pharmaceutical product, and the shaft backflush channel is connected to the outside of the implant shaft via at least one shaft backflush hole (14, 14′; 114; 214) for receiving the discharged pharmaceutical product. The flush supply opening is fluidically connected to the proximal end of the shaft flush channel and the backflush opening is fluidically connected to the proximal end of the shaft backflush channel. Also disclosed is a joint implant comprising two such joint implant components which are connected to one another by means of joint surface parts (30, 40; 230) and are pivotable relative to one another.

TRIAL NECK AND METHOD

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.
