Spontaneous modular femoral head dissociation complicating total hip arthroplasty.
Modular femoral heads have been used successfully for many years in total hip arthroplasty. Few complications have been reported for the modular Morse taper connection between the femoral head and trunnion of the stem in metal-on-polyethylene bearings. Although there has always been some concern over the potential for fretting, corrosion, and generation of particulate debris at the modular junc...
متن کاملRadiographic manifestation of hip dislocation after total hip arthroplasty.
OBJECTIVE The authors hypothesized that a patient who has posterior hip dislocation after total hip replacement does not have the same clinical manifestations of malposition as with a natural hip. The present study aimed to study clinical manifestation of hip dislocation after total hip arthroplasty. MATERIAL AND METHOD Thirty-five cases of posterior dislocation after total hip replacement we...
متن کاملCementless Total Hip Arthroplasty Involving Trochanteric Osteotomy without Subtrochanteric Shortening for High Hip Dislocation
BACKGROUND Total hip arthroplasty with subtrochanteric shortening osteotomy is widely performed for high hip dislocation. However, suboptimal leg length discrepancy correction and nonunion of the osteotomy site remain concerns. Although total hip arthroplasty using trochanteric osteotomy without subtrochanteric osteotomy was introduced, cemented implants have been more commonly used than contem...
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...
متن کاملClinical Cold Welding of the Modular Total Hip Arthroplasty Prosthesis.
BACKGROUND A head that is "clinically cold welded" to a stem is one of the commonest reasons for unplanned removal of the stem. It is not clear which hip designs are at greatest risk of clinical cold welding. METHODS This was a case-control study of consecutively received hip implant retrievals; we chose the design of hip that had the greatest number of truly cold-welded heads (n = 11). For o...
