Hip implant assembly

An implant for replacing the proximal portion of a femur having a substantially intact natural femoral neck, medial side, lateral side, greater trochanter and lesser trochanter, the implant comprising:

• a body member having a longitudinal axis, a distal end and a proximal end and being configured for positioning, in use, in the natural femoral neck,
• wherein the body member has a transverse passage through at least a portion of the distal end in a direction transverse to the longitudinal axis of the body member;
• a head member having a distal end and a proximal spherical portion configured for positioning in a natural or prosthetic hip socket;
• a joining portion positioned between the distal end of the head member and the proximal end of the body member;
• and
• a rod having a longitudinal axis, a proximal end and a distal end and being configured for positioning, in use, through the transverse passage of the body member,
• the rod having a stabilizing passage through at least a portion of the rod in a direction transverse to the longitudinal axis of the rod.

An implant for replacing the proximal portion of a femur having a substantially intact natural femoral neck, medial side, lateral side, greater trochanter and lesser trochanter, the implant comprising:

• a body member having a longitudinal axis, a distal end and a proximal end and being configured for positioning, in use, in the natural femoral neck,
• wherein the body member has a transverse passage through at least a portion of the distal end in a direction transverse to the longitudinal axis of the body member;
• a head member having a distal end and a proximal spherical portion configured for positioning in a natural or prosthetic hip socket;
• a joining portion positioned between the distal end of the head member and the proximal end of the body member;
• and
• a rod having a longitudinal axis, a proximal end and a distal end and being configured for positioning, in use, through the transverse passage of the body member, wherein the rod, in use, extends in substantially coaxial alignment relative to the longitudinal axis of the femur and the rod and the body member are slidably and lockingly engaged.

An implant for replacing the proximal portion of a femur having a substantially intact natural femoral neck, medial side, lateral side, greater trochanter and lesser trochanter, the implant comprising:

• a plurality of modular components of varying sizes within anatomical ranges for accommodating varying patient body dimensions, the components comprising:
• a body member having a longitudinal axis, a distal end having a transverse passage in a direction transverse to the longitudinal axis of the body member and a locking passage in a direction substantially coaxial to the longitudinal axis of the body member, a proximal end having an engagement surface thereon, the body member being coated on at least a portion thereof with at least one layer of a material for promoting bone ingrowth and being configured for positioning, in use, in the natural femoral neck;
• a head member having a distal end and a proximal spherical portion configured for positioning in a natural or prosthetic hip socket, the distal end of the head member having an engagement surface configured for complementary engagement with the engagement surface of the proximal end of the body member for joining the distal end of the head member to the proximal end of the body member;
• a member for optionally altering the position of the spherical potion of the head member relative to the body member;
• and
• a rod having a proximal end and a distal end, wherein the rod extends through the transverse passage of the body member and is in substantially coaxial alignment relative to the longitudinal axis of the femur.
