Short-stem prostheses: marketing effect or real benefit?
This presentation explores the advantages and limitations of short-stem hip replacements. It evaluates their reliability, impact on bone preservation, specific indications, and long-term clinical outcomes. Practical cases and 3D planning illustrate the potential benefits of this minimally invasive solution.

Short-stem prostheses: principles and objectives
Short stems are designed to respect anatomy and preserve proximal bone stock. They distribute loads better and are readily integrated into a minimally invasive approach.
Patient selection and scheduling
The morphology of the femoral neck, bone quality and the axis of the femur guide the indication.
3D planning checks for stability and restoration of offset and length.
Reconstructing the hip as close as possible to the original anatomy is the guiding philosophy.
Results and reliability
Published series show satisfactory clinical results and good medium-term survival, with preservation of proximal bone.
Potential benefits include less torsional stress and accommodation for varied femurs.
Limitations and contraindications
Some morphologies (very wide canal, short/thick cervix, major deformities) are not suitable for short stems. In these cases, a standard or custom stem may be preferable.
Careful selection of patients determines the real benefit beyond the fad effect.
What this means for the patient
The strategy aims for immediate stability, restoration of muscle levers and rapid functional recovery. Radiological monitoring verifies the integration of the implant over time.
Key message
Short stems are not a one-size-fits-all solution. They are useful when the anatomy is suitable and 3D planning validates stability and biomechanical reconstruction.
