Todd Swanson, MD, an orthopedic surgeon in Las Vegas, has been working with Smith & Nephew Orthopedics and other surgeons to design a new mini-stem total hip prosthesis for young patients, according to a release from Dr. Swanson.

Dr. Swanson has completed 17 surgeries with the prosthesis, including one on a 17-year-old male who needed a total hip replacement because of a slipped capital femoral epiphysis, a developmental disorder of the hip ball, that resulted in chondrolysis (destruction of the hip joint cartilage) at a very young age.

The new tapered geometry stem is made of a lightweight, durable titanium alloy and is compatible with high-demand, femoral head-bearing options, such as ceramic-ceramic, metal-metal, and highly crosslinked polyethylene.

The device's hip stem is shorter than conventional hip stems in order to conserve more of the femur than other prostheses.

Dr. Swanson is a member of the 19-physician Desert Orthopaedic Center in Las Vegas.
