Evaluation of reimplant total hip prostheses and resection arthroplasty.
Results of reimplanted total hip prostheses and resection arthroplasty were compared. Using the Iowa hip rating scale, the reimplanted prostheses population was rated higher for function, gait, and absence of deformity, however, the resection arthroplasty population rated better in freedom from pain. Radiographic findings in the reimplanted prostheses population included radiolucent lines around the cement, loosening, and cortex bone stock loss. These findings cause concern for the future of these implants. Repair and remodeling of the bone lesions were observed in resection arthroplasties. It was concluded that if healing of infection is achieved or if resection is performed for mechanical failure, the results may be considered permanent.
