Preserving natural anatomy and restoring patient biomechanics

About
Today’s conventional hip implants were designed for yesterday’s patient. Are we being conservative enough for today's patients? With clinically proven results1, MiniHip is designed to enable the restoration of multiple anatomies and is an ideal solution for active patients.

Conserving bone
MiniHip is designed to provide the bone preserving benefits of hip resurfacing with the stability of traditional total hip replacement2.
With MiniHip, typically a mid-neck resection is defined from the centre of rotation resulting in:
- Trochanter conservation
- Neck preservation
- Diaphyseal sparing
MiniHip aims to preserve significantly more bone stock in the femoral neck, helping promote more natural, physiological loading3.
Preserving soft tissue
Although suitable for all approaches, the MiniHip stem shape allows it to be implanted via the Direct Anterior Approach and thus is designed to be less invasive to soft tissues.
It follows natural anatomy by going ‘around the corner’ of the calcar.
Specialised DAA instrumentation can be used in conjunction with the MiniHip system to implant via minimally invasive procedures – DAA specialised table is also available.
Restoring biomechanics
The size and shape of the stem, coupled with the retention of the femoral neck enables restoration of the biomechanics of multiple anatomies:
- Neck resection preserves bone in the calcar region.
- Offset, leg length and CCD reproducibility4.
- Restores anteversion by retaining a portion of the femoral neck5.
Select MiniHip during preoperative planning of THAs using OPSInsight™ for a patient-specific, optimised plan and solution.
