The femoral component of the prosthesis in most designs is smaller in length than conventional total hip replacements. There is no change in the socket size.

The main advantage is that more of patient’s own bone is preserved. This is like having more money in your saving’s account for the future. When in the future, a re do operation becomes necessary, the surgeon can just perform a conventional THR instead of a revision hip. Revision surgery has to address bone loss which is negligible with properly done short stem hip replacement.

Another advantage relates to morbidity and mortality. Studies have shown that 1 in 23 patients receiving a cemented total hip replacement is likely to die. This has been attributed to the cementing process. Even un- cemented total hip replacements also are associated with higher mortality than hip resurfacings and short stem hip replacements. The cause is embolisation of bone marrow and cement into the lungs arising from the stem being driven into the medullary canal. This does not occur with short stem hip replacements as the femoral component is only anchored in the spongy bone where there is not much marrow.

Short stem hip replacements are hence the safest and most durable option. One need not worry about the bearing materials used as all variety of bearings can be used. Ceramic, metal, cross linked polyethylene can all be used.

They are recommended in young and active patients with hip arthritis. Examples of short stem prostheses available in India are METHA stem, Tri lock hip and CFP stem. I introduced the short stem Proxima hip replacement to the region in 2006. See a patient testimonial here.
