On stabilization of loosened hip stems via cement injection into osteolytic cavities.
BACKGROUND Cement injection into osteolytic areas around the cement mantle is a technique for refixation of loose hip implants for patients who cannot undergo standard revision surgery. Preliminary clinical results show the improvement in walking distance, patients' independence and pain relief. METHODS In this study, we use a detailed finite element model to analyze whether cement injection ...
متن کاملGene therapy and cement injection for restabilization of loosened hip prostheses.
Loosening of orthopedic hip prostheses is an increasing health problem. In elderly patients with comorbidity,revision surgery may lead to high mortality rates. A less invasive surgical technique is therefore required to reduce these patient risks. To this end a percutaneous gene therapy approach was designed to destroy the periprosthetic loosening membrane, and enable refixing of the hip prosth...
متن کاملOsteolytic changes around biodegradable cement restrictors in hip surgery
Background and purpose - Biodegradable cement restrictors are widely used in hip arthroplasty. Like others, we observed osteolytic reactions associated with a specific cement restrictor (SynPlug; made of PolyActive) and reviewed our patients. Patients and methods - We identified 703 patients with suitable radiographs from our database (2007 to 2012) who underwent cemented hip arthroplasty and r...
متن کاملCement debonding process of total hip arthroplasty stems.
Retrieval studies have indicated that debonding of the stem cement interface in total hip arthroplasty precedes clinical failure of femoral components. This study addressed the mechanisms that play a role in the debonding process by analyzing how debonding is likely to proceed in the course of time. It was investigated whether debonding is an immediate process or if it is likely to develop slow...
متن کاملFractures of Corin 'Taper-Fit' CDH stems used in 'cement-in-cement' revision total hip replacement.
We describe two cases of fracture of Corin Taper-Fit stems used for cement-in-cement revision of congenital dysplasia of the hip. Both prostheses were implanted in patients in their 50s, with high offsets (+7.5 mm and +3.5 mm), one with a large diameter (48 mm) head and one with a constrained acetabular component. Fracture of the stems took place at nine months and three years post-operatively ...
