The COLLO-MIS stem was designed to save bone tissue and ensure a rapid functional recovery.
By sparing the femoral neck without the risk of unequal leg length and compressing the cancellous bone, an anatomically accurate reconstruction is ensured while also saving as much of the patient’s bone stock as possible.
The stem geometry and double macroporous coating provide for immediate stability and the restoration of the biomechanical balance required for optimal osteointegration.
The freedom to choose the preferred soft tissue-sparing approach and the latest generation tribological couplings in terms of materials and diameters combine to hasten the patient’s functional recovery.

The lateral profile is tapered to maximise primary stability and the two proximal antero-posterior fins ensure rotational stability.
The implant neck is designed to reduce the risk of unequal leg length and improve range of motion without the risk of impingement.
The medial curvature varies according to the stem size to better fit the cortical bone and promote physiological load transfer, and the distal tip is uncoated to prevent stress shielding.
The number of sizes and minimal differences between the sizes help to ensure adequate stability irregardless of bone tissue conditions, as well as good cancellous bone compression across all femoral anatomies.

The COLLO-MIS stem is designed for patients with primary or secondary hip joint arthrosis, avascular or post-traumatic femoral head osteonecrosis, without severe deformities or prior surgery and/or diseases causing alterations of the femoral neck.
