Modular hip implant fracture at the stem-sleeve interface.
The use of modular implants in femoral stem design has grown increasingly popular over the last decade because of the theoretical advantage of more flexibility and optimization of femoral anteversion, limb length, and femoral component offset. With the benefit of increased surgical flexibility, however, modularity also carries the theoretical risks of fretting at the modular surfaces, sequelae ...
متن کاملLong-Term Results of Cementless Total Hip Arthroplasty Using a Modular Stem in Patients with Femoral Head Osteonecrosis
Cementless modular stemwas designed to allow the surgeon to independently match the anatomy of the metaphyseal and diaphyseal regions of the femoral canal of an individual patient.1 S-ROM stem (DePuy/Johnson & Johnson), which has a hollow proximal sleeve and separate cylindrical core, was introduced in 1984. So far, long-term results of this prosthesis have been excellent in osteoarthritis, dev...
متن کاملStanmore stem long-term survivorship
Development of the Stanmore hip system Following its development at the Department for Biomedical Engineering, Royal National Orthopaedic Hospital Stanmore the Stanmore stem was first implanted in 1973. The original design was manufactured from cast CoCr alloy (AliviumTM) which was supplemented by a forged titanium alloy (TivaloyTM) version in 1979. At this time both the CoCr and titanium alloy...
متن کاملFailure of a modular hip implant at the stem-sleeve interface.
In the current era of total hip arthroplasty (THA), orthopedic surgeons have several fixation options at their disposal. The modern monoblock prosthesis, introduced by Dr. Sir John Charnley, has seen many modifications since its inception in the 1970s and continues to be the most commonly used prosthesis style for primary and revision THA. Proximal modular sleeve technology was introduced in 19...
متن کاملTotal Hip Arthroplasty with Modular Stem for Dysplastic Hips in South Asian Population
Introduction: Optimum component positioning and orientation is required to optimize the functional result during total hip arthroplasty for dysplastic hips. Patients and methods: Sixty-two patients (66 hips) including 33 males and 29 females underwent total hip arthroplasty using modular stem prosthesis at an average age of 40.6 years (range 17 to 49 years). Nineteen hips were clas...
