Rapid Destruction

Rapid destructive hip osteoarthritis is a diagnosis by exclusion. It should be differentiated from septic arthritis, osteonecrosis, neuropathic arthritis and other aetiologies causing rapid bone resorption or destruction around the hip. The present study aims to review the incidence of rapid destructive hip osteoarthritis among those patients who request total hip arthroplasty for end stage arthrosis. A retrospective review of radiographs of all patients who scheduled for total hip arthroplasty from January 2010 to March 2019 were analysed by 3 orthopaedic fellows. Of 174 hips of 146 patients, 35 hips of 29 patients were considered by at least 2 orthopaedic fellows to have rapid destructive hip osteoarthritis based on radiographic criteria of rapid joint space narrowing or rapid destruction of femoral head with or without acetabular involvement. Clinical history and physical finding, blood biochemistry, cultures and pathology with or without frozen section are reviewed. Early total hip arthroplasty, rather than routine operation in the long waiting list, is recommended for rapid destructive hip osteoarthritis to prevent technical difficulty in dealing with the bone loss or defect associated with rapid destructive hip osteoarthritis. However, one must exclude septic arthritis before proceeding to total hip arthroplasty. In clinically highly suspected cases, staged total hip arthroplasty was done despite of normal initial blood investigationsand negative hip aspiration with equivocal frozen section on table. In one such patient, the culture was initially negative, but became positive only after extended period of culture. On the other hand, rapid destruction of acetabulum requiring impaction bone grafting and acetabular augmentation for total hip arthroplasty was needed in one patient. Malignancy was suspected in another patient, but there was no evidence of malignancy or infection in the femoral head and tissue obtained by excisional arthroplasty of hip. One patient with hip pain and bilateral hip involvement was found to have Charcot joint. Rapid destruction hip osteoarthritis represents an uncommon subset of arthrosis with rapid progression. A delicate balance between correct diagnosis and timely early operation should be exercised to prevent rapid loss of bone stock making delayed total hip arthroplasty become technical difficult with possible compromised outcomes.

Femoral Head Osteonecrosis

In recent years, there has been an increase in the number of studies on the etiology of femoral head necrosis. We retrospectively reviewed all patients diagnosed with aseptic necrosis of the femoral in the period of 2010-2015. We recorded a total of 230 cases diagnosed with aseptic necrosis of the femoral head, group was composed of 65.7% men and 34.3% women, risk factors identified was 19.13% (post-traumatic), 13.91% (glucocorticoids), 26.52% (alcohol), 3.47% (another cause) and in 36 95% of the cases no risk factors were found. The results of the study based on the type of surgery performed on the basis of stages of disease progression, 8 patients (3.48%) benefited from osteotomy, 28 patients (12.17%) benefited of bipolar hemiarthroplasty prosthesis and 188 patients (81.74%) benefited of total hip arthroplasty. Osteonecrosis of the femoral head is characteristic to young patients between the age of 30-50 years old. Predisposing factors, alcohol and corticosteroid therapy remains an important cause of the disease. Total hip arthroplasty remains the best option for the patients with osteonecrosis of the femoral head.

Templating Technique

AbstractPreoperative templating for total hip arthroplasty (THA) is fraught with uncertainty. Specifically, the conventional measurement of the lesser trochanter to the center (LTC) of the femoral head used in preoperative planning is easily measured on a template but not measurable intraoperatively. The purpose of this study was to examine the utility of a novel measurement that is reproducible both on templating and in surgery as a more accurate and practical guide. We retrospectively reviewed 201 patients with a history of osteoarthritis who underwent primary THA. For preoperative templating, the distance from the top of the lesser trochanter to the equator (LeTE) of the femoral head was measured on a calibrated digital radiograph with a neutral pelvis. This measurement was used intraoperatively to guide the choice of the trial neck and head. As with any templating technique, the goal was to construct a stable, impingement-free THA with equivalent leg lengths and hip offset. In evaluating this novel templating technique, the primary outcomes measured were the number of trial reductions and the amount of fluoroscopic time, exposures, and radiation required to obtain a balanced THA reconstruction. Using the LeTE measurement, the mean number of trial reductions was 1.21, the mean number of intraoperative fluoroscopy images taken was 2.63, the mean dose of radiation exposure from fluoroscopy was 0.02 mGy, and the mean fluoroscopy time per procedure was 0.6 seconds. In hips templated with the conventional LTC prior to the LeTE, the mean fluoroscopy time was 0.9 seconds. There was a statistically significant difference in fluoroscopy time (p < 0.001). The LeTE is a reproducible measurement that transfers reliably from digital templating to surgery. This novel preoperative templating metric reduces the fluoroscopy time and consequent radiation exposure to the surgical team and may minimize the number of trial reductions.

The purpose of this study was to examine the effects of ceramic femoral head material on the wear of annealed, crosslinked ultra-high molecular weight polyethylene (UHMWPE) (XLPE) in total hip arthroplasty compared to non-crosslinked conventional UHMWPE (CPE). XLPE was fabricated by crosslinking with 60 kGy irradiation and annealing. Femoral heads made from zirconia and alumina ceramics, and cobalt-chrome (CoCr) of 22 mm or 26 mm diameter were used. In this study, the femoral head penetration into the cup was measured digitally on radiographs of 70 hips with XLPE and 50 hips with CPE. The average follow-up periods were 6.1 and 12.7 years, respectively. The steady wear rate of XLPE was significantly lower than those of CPE (0.002 versus 0.08 mm/year, respectively). Zirconia displayed increased wear rates compared to alumina in CPE; however, there was no difference among head materials in XLPE (0.0028, 0.011 and 0.009 mm/year for zirconia, alumina and CoCr, respectively). Neither head size or implantation period impacted XLPE wear. In contrast to CPE, XLPE displayed low wear rates surpassing the effects of varying femoral head material, size, implantation period and patient demographics.

Aims We aimed to evaluate the long-term outcome of highly cross-linked polyethylene (HXLPE) cemented acetabular components and assess whether any radiolucent lines (RLLs) which arose were progressive. Methods We retrospectively reviewed 170 patients who underwent 187 total hip arthroplasties at two hospitals with a minimum follow-up of ten years. All interventions were performed using the same combination of HXLPE cemented acetabular components with femoral stems made of titanium alloy. Kaplan-Meier survival analysis was performed for the primary endpoint of acetabular component revision surgery for any reason and secondary endpoint of the appearance of RLLs. RLLs that had appeared once were observed over time. We statistically assessed potential relationships between RLLs and a number of factors, including the technique of femoral head autografting and the Japanese Orthopaedic Association score. Results The mean follow-up period was 13.0 years (10.0 to 16.3). Femoral head autografting was performed on 135 hips (72.2%). One acetabular component was retrieved because of deep infection. No revision was performed for the aseptic acetabular loosening. The Kaplan-Meier survival curve for the primary and secondary endpoints were 98.2% (95% confidence interval (CI) 88.6% to 99.8%) and 79.3% (95% CI 72.8% to 84.6%), respectively. RLLs were detected in 38 hips (21.2%), at a mean of 1.7 years (1 month to 6 years) postoperatively. None of the RLLs were progressive, and the presence of RLLs did not show a significant association with the survival and clinical score. RLLs were more frequently observed in hips without femoral head autografts than in those with autografts. Conclusion The use of HXLPE cemented acetabular components in total hip arthroplasty demonstrated excellent clinical outcomes after ten years, and no RLLs were progressive, and their presence did not affect the outcome. Femoral head autografting did not negatively impact the acetabular component survival or the appearance of RLLs. Cite this article: Bone Joint J 2021;103-B(10):1604–1610.
