Uncemented Total Hip Arthroplasty in Patients with a History of Pelvic Irradiation for Prostate Cancer

Purpose. To compare the quantity of bone removed from the acetabulum during resurfacing hip arthroplasty versus uncemented total hip arthroplasty (THA). Methods. 62 consecutive patients with osteoarthritis of the hip were prospectively studied. 24 men and 7 women aged 40 to 86 (mean, 59) years underwent Birmingham hip resurfacing. 13 men and 18 women aged 34 to 88 (mean, 61) years underwent uncemented THA using the trident acetabular cup. Obese elderly women at risk of femoral neck fracture and patients with large subchondral pseudocysts or a history of avascular necrosis of the femoral head were assigned to uncemented THA. Acetabular reamings were collected; marginal osteophytes were not included. The reamings were dehydrated, defatted, and weighed. Results. The mean weight of acetabular reamings was not significantly different between patients undergoing hip resurfacing and uncemented THA (p=0.57). Conclusion. In hip resurfacing, the use of an appropriately small femoral component avoids oversizing the acetabular component and removal of excessive bone stock.

Insight Into

AbstractThe aim of this study was to assess a large, single-surgeon dataset of uncemented total hip arthroplasties that had been templated using software. This assessment compared preoperative templated predictions with what was implanted with regard to (1) femoral prosthesis size and (2) acetabular cup size. The operation notes for two types of uncemented total hip arthroplasty performed by a single surgeon between January 9, 2008, and March 21, 2019, were assessed. The data were refined so that only those that were fully templated on a correctly calibrated pelvic radiograph were included. This provided a total of 153 cases. The predicted software template was compared with actual implanted component sizes. With regard to the femoral stems, the templating software was exactly correct in 45.75% of cases and was accurate to within one size in 87.59% of cases. With regard to the acetabular component, the templating software was exactly correct in 52.94% of cases and was accurate to within one size (2 mm) in 86.94% of cases. Templating software offers an accurate prediction of the size of uncemented femoral and acetabular components. In addition, the benefits of templating include cognitive rehearsal, insight into potentially challenging aspects of surgery, and highlighting intraoperative issues where there is a large intraoperative deviation from what is templated. This study demonstrates the congruence and reproducibility of templating software when compared with other smaller studies performed in the literature.

Automated Methods

Abstract Background Total nucleated cell (TNC) count and differential are used to classify joint effusions as inflammatory or noninflammatory. Further diagnostic evaluation and management is contingent on this classification. TNC count can be measured by automated analyzers or by manual assessment using a hemocytometer. Studies have raised concerns regarding the accuracy of TNC counts measured by automated instruments, particularly in the setting of joint arthroplasty. The objective of this study was to determine whether metallosis, a complication of total hip arthroplasty in which metal debris accumulates in periprosthetic tissues and synovial fluid, is associated with inaccurate TNC counts in synovial fluid. Methods We compared the accuracy of cell counts measured by the Sysmex XN-1000 and Beckman Coulter Iris iQ200 with the gold standard of manual assessment using a hemocytometer in synovial fluid from patients with suspected metallosis and in fluid obtained from controls from patients with native joints and a history of arthroplasty for other indications. Results TNC counts produced by automated analyzers were associated with increased levels of discordance (relative to manual counts) in patients with metallosis. Metallosis was not associated with increased levels of discordance for RBC counts or WBC differentials. The Sysmex XN flagged all but 1 metallosis sample for manual verification of the results. Conclusions Automated methods are generally reliable for analysis of synovial fluid. TNC counts can be inaccurate in the context of metallosis following total hip arthroplasty. Laboratories should correlate automated cell counts with a microscopic assessment of the specimen, as recommended by instrument manufacturers.

Musculoskeletal Manifestations

Children affected by mucopolysaccharidosis (MPS) type IH (Hurler Syndrome), an autosomal recessive metabolic disorder, are known to experience a range of musculoskeletal manifestations including spinal abnormalities, hand abnormalities, generalised joint stiffness, genu valgum, and hip dysplasia and avascular necrosis. Enzyme therapy, in the form of bone marrow transplantation, significantly increases life expectancy but does not prevent the development of the associated musculoskeletal disorders. We present the case of a 23-year-old woman with a diagnosis of Hurler syndrome with a satisfactory result following uncemented total hip arthroplasty.
