Duarte GMH, Pires RE, Machado CJ, et al. - This study was carried out to assess the clinical and radiographic results of patients who had presented cavitary, segmental, and combined acetabular defects and received total hip arthroplasty (THA)/acetabular reconstruction (AR) involving impacted morselized cancellous bone autografts followed by rigorous postoperative management. Researchers retrospectively evaluated clinical outcomes of 154 patients who had been submitted to 169 THA/AR procedures conducted by a single surgeon over a 15-year period. They used the Harris Hip Score system to 103 patients, and the degree of acetabular migration was ascertained from radiograph images of 91 AR procedures, of which 40 were segmental/combined and 51 were cavitary reconstructions. The presented THA/AR method can be applied effectively in the reconstruction of segmental/combined and cavitary acetabular defects. IT was shown that the significance of the technique as used to segmental/combined defects was attributed in part to the rigorous rehabilitation protocol with temporary postoperative weight-bearing restriction.
