Metha® Short Hip Stem

The Metha® short cementless hip prosthesis stem is anchored directly within the closed ring of the femoral neck and metaphysis. Metha® preserves valuable muscle and bone structures and leads to a high primary loading stability and natural femoral antetorsion.

Modular neck adapters
Metha® modular neck adapters offer different offset and torsion variations following the implant position of the stem. Joint stability and range of motion can be adjusted by taking into account the soft tissue tension and implant position.

Plasmapore® µ-CaP surface
Metha® features the proximal rough Plasmapore® titanium micro-porous coating for cementless implantation. An additional 20 µm calcium phosphate layer is applied electrochemically. This thin layer has an osteoconductive effect and accelerates contact between the bone and the prosthesis stem.

OrthoPilot® hip navigation
Combining the modular Metha® hip stem with OrthoPilot® navigation technology expands the possibilities for endoprosthetic treatment. The free choice in the sequence of cup an stem implantation and the modular neck adapters take account of the individual joint situation – resulting in the optimised range of hip motion.

MIOS® operating techniques
The higher osteotomy and the more medial location of the femoral access make Metha® ideally suited for minimally invasive implantation techniques. The MIOS® – Minimally Invasive Orthopeadic Solutions – instrument range has been carefully and specially designed for such procedures and gives an excellent support of most frequent hip approaches.
