Short Femoral Stems For Total Hip Arthroplasty


Short femoral stems, also named metaphyseal stems, have been designed and introduced into the surgical practice in order to improve the results of the standard non-cemented stems. A wide range of short stems are available, with differences in design, surgical technique, and published outcomes.


Several advantages have been advocated in favor of short stems over standard non-cemented stems. Short stems:

  • Preserve the proximal femoral bone stock
  • Decrease stress shielding
  • Decrease the tight pain rate
  • Ease minimally invasive surgical procedures
  • Improve long-term stem survival
  • Ease the surgical procedure during revision


There are two main groups of short stems, those that are neck-preserving and those that do not preserve the femoral neck. Another feature that differentiates them in the availability of modularity.

List of short stems

Mayo Conservative Stem (Zimmer) - Non-neck preserving and no modularity
CFP - Neck-preserving, no modularity
Metha (Aeesculap) - Neck-preserving, modularity
Cut (ESKA) - Neck-preserving, no modularity
Taperlock Microplasty (Biomet) - Neck-preserving, no modularity
Nanos (Smith and Nephew) - Neck-preserving and no modularity
Proxima Stem (DePuy) - Can be neck-preserving, no modularity
Silent (DePuy) - Neck-preserving, no modularity
Mini Hip (Corin) - Neck-preserving, no modularity
Collo-MIS (Lima) - Neck-preserving, no modularity


Mayo Conservative Stem (Zimmer)

  • Survival 98.2% without mechanical loosening at 5 and 10 years (Morrey et al, 2000)


  • Survival 97% at 3 years (Gill et al, 2010)
  • Survival 100% at 3,1 years (Pons, 2010)

Cut (ESKA)

  • Survival 98% at 6.6 years (Steens et al, 2010)


  • Survival 100% at 1 year (Synder et al, 2009)

Proxima Stem (DePuy)

  • Survival 100% at 8 years (Santori et al, 2010, reporting the precursor stem of the Proxima)
  • Survival 100% at 2.1 years (Tóth et al, 2010)
  • Survival 100% at 1.7 years (Ghera et al, 2009)

Pearls and Pitfalls

  • Routine radiographic controls during the surgery is recommended during the learning curve.
  • The use of short anatomical stems in hip dysplasia can lead to an excessive anteversion of the femoral component that can predispose to dislocation. Careful planning must be done for these cases, and a standard stem allowing to control femoral version has to be available as an alternative option during the surgical procedure. 
  • A short stem can be a valuable option in cases with severe femoral deformity or presence of previous implants, or even to ease the revision of a fractured hydroxyapatite fully coated femoral stem (a case report about this last option has been described by Sangüesa-Nebot et al, 2010)


  • Many of the medium- and long-term results published to date correspond to the author or authors of the implant; the results have to be observed carefully. 
  • The learning curve of this stem is assumed to be equal to conventional stems, but no series address it.
  • The influence of conditions such as obesity, metabolic bone diseases, or osteoporosis on the stem survival rate is yet to be defined.
  • The failure pattern of these stems is yet to be known; it still has to be proved that the surgical revision is eased and that the revision can be done with a primary conventional stem.
