Fixion Hip System |
 .jpg) 
The Fixion Hip System is intended for use as a Hemi-Hip or as Total-Hip replacment**. The system is composed of an expandable stem, which provides homogeneous load distribution along its length (press fit fixation); and a neck of a conical stepped configuration that improves rotational resistance.
* Hemi-Hip:
♦ Uni & Bi-Polar: CE marked

* Total-Hip
♦ Cleared for marketing by the FDA
 FEATURES
HIP SYSTEM
- Minimally invasive procedure.
- Cementless and cemented procedures.
- Press fit fixation to the bone.
STEM BODY
- Inserted in a reduced diameter and expanded within the medullary canal using saline solution.
- Less reaming is required as the stem adapts to the contours and shape of the medullary canal through expansion.
- Fixation to the cortex is achieved along the entire length of the stem.
- Grooves on the stem longitudinal bars improve axial holding force.
STEM NECK
- Angled 135° to the stem body.
- Tapered 12/14 mm.
PRINCIPLES OF OPERATION
The Fixion Hip Stem is supplied with its distal section in a reduced diameter. It is inserted into the femoral canal utilizing the Fixion Hip Handle. Once in position, the head ball is connected to the stem neck trunnion. After final postioning of the stem, the distal section is expanded under controlled pressure, utilizing a pump. The abutement of the longitudinal bars of the stem's distal section against the inner surface of the femoral canal and the stem neck's conical stepped configuration provide excellent immediate fixation.
INDICATIONS
The Fixion Hip System is intended for use as a hemi-hip or total-hip replacment.
The Fixion Hip System is indicated as unipolar or bipolar hemi-hip replacement in cases of:
- Femoral head and/or neck fractures or non-unions.
- Aseptic necrosis of the femoral head and/or neck.
- Osteo-, rheumatoid-, and/or post-traumatic arthritis of the hip, with minimal acetabular involvement.
The Fixion Hip System is indicated as a total hip replacement in cases of:
- Painful, disabling joint disease of the hip resulting from: degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis or late stage avascular necrosis.
- Revision of previous unsuccessful femoral head replacement, cup arthroplasty or other procedure.
- Clinical management problems where arthrodesis or alternative reconstructive techniques are less likely to achieve satisfactory results.
The Fixion Hip Stem is intended for cemented or non-cemented use.
