Metha® Short Hip Stem System

Anatomic Accuracy

Metha<sup>®</sup> Short Hip Stem System

The Metha Short Hip Stem is designed to achieve true metaphyseal anchoring for cementless Total Hip Arthroplasty (THA). The combination of a bone-conserving design and anatomic accuracy have been proven to meet the needs of both patient and surgeon.

The System:

The Stability:

  • Read the Metha Five-Year Survivorship Study
    • Hip prosthesis stems with a short stem length and proximal fixation geometry support bone-preserving and muscle-sparing implantation and should also allow for revision surgery with a standard hip stem. Presented are 250 prospectively-documented clinical and radiological results from the Metha Short Hip Stem prosthesis. A five-year Kaplan-Meier survival rate of 96.7% was determined for the short hip stem prosthesis.
    • ACCESS THE STUDY FOR COMPLETE CLINICAL RESULTS

The Integrity:

  • The preserved bone stock allows for an improved potential revision situation where a standard implant can be used instead of a longer revision stem.

The Metha Short Hip Stem is fixated by metaphyseal anchoring within the closed ring of the femoral neck. Medial stem placement upon the calcar combines with a conical shape to support primary stability and proximal force transfer.

  Post-cam view

The stem anteversion and head position of the Metha Short Hip Stem, guided by the femoral neck upon implantation, are anatomically accurate, to restore natural biomechanics and ensure excellent joint stability.

The minimal lateral shoulder combined with a high neck osteotomy site eliminates disruption of the greater trochanter and preserves surrounding tissue, while the reduced length conserves bone in the distal femoral canal.

Anterior and posterior narrowing

The Plasmapore® µ-CaP advanced coating technology is a combination of a microporous Ti-plasma rough coating and thin bioactive calcium phosphate surface finish. The enhanced surface encourages biological fixation through osseointegration to ensure long-term survivorship. Aesculap has been applying Plasmapore technology to orthopaedic implants for over 25 years.
