Another AAOS Launch: United Orthopedic Corporation’s UTS™ Hip Stem

United Orthopedic Corporation is at the American Academy of Orthopaedic Surgeons (AAOS) Annual Meeting in New Orleans where it has launched the UTS™ hip stem and an extension of the U-Motion II™ Acetabular System.


The demand for primary total hip arthroplasties is estimated to grow by 174% to 572,000 by 2030, while the demand for hip revisions is projected to double by 2026. Dislocation continues to be one of the most common causes of failure after primary and revision total hip arthroplasty. Clinical studies show large femoral heads decrease the incidence of dislocation after total hip arthroplasty.

United Orthopedic Corporation, is a leading international designer, manufacturer and distributor of innovative orthopedic implants and instruments. Its newly launched (United Tri-tapered Short Stem) UTS™ hip stem is described by the company as being ideal for the direct anterior approach for total hip replacement. Its tapered wedge short stem design is said to be suitable for less invasive primary hip replacement surgery. It is designed for easier insertion through small incisions and requires simpler femoral preparation, enabling rapid recovery. Shorter stems preserve bone, which allows for more favorable conditions in future revisions.

The UTS™ hip stem is available in 14 refined proximal sizes. Its features include:

  • Standard and high offset options for restoring joint biomechanics
  • Triple taper design with Titanium Plasma coating that provides initial fixation and enhances rotation stability
  • Reduced lateral shoulder designed to conserve bone in the greater trochanter

The company has also announced the extension of the U-Motion II™ Acetabular System for total hip replacement surgery to include a 50mm acetabular cup and cup liner, compatible with the 36mm BIOLOX® delta ceramic and CoCrMo metal femoral heads. The pole thickness of the liner is 5.3mm, which is greater than ISO 21315’s requirement of 5mm to reduce the risk of breakage. The 36mm femoral head with the new U-Motion II™ 50mm Acetabular cup will provide patients a greater range of motioniv, increase jumping distance, improve stability and lower the risk of dislocation.

Company comments

“We are committed to developing quality, innovative orthopedic products that improve patient outcomes and address the market’s needs,” said Calvin Lin, President of United Orthopedic Corporation USA. “Our unique vertically integrated manufacturing model has enabled us to launch two products which provide surgeons with more treatment options for total hip replacement. One is the UTS™ hip stem, which facilitates less invasive surgery and aids in rapid recovery. The other is a new cup and cup liner – an extension of the U-Motion II™ Acetabular System – which is designed to reduce the risk of dislocation following a total hip replacement.”
