Background/Aim. Anatomical parameters of the bony components of the hip joint are essential for better understanding of etiopathogenesis of diseases like primary osteoarthrosis of the hip joint. The aim of this reserch was to examine the normal acetabular morphometry in Serbian population and to determine whether there are sex differences in anatomical parameters of the acetabulum among asymptomatic subjects. Methods. Pelvic radiographics of 320 adult asymptomatic patients (640 hips) were analyzed in 170 men and 150 women to determine the morphology of the acetabulum in Serbian population. For each hip the center edge angle of Wiberg (CEA), the acetabular angle of Sharp (AA), acetabular depth (AD), acetabular roof obliquity (ARO) and roof angle (RA) were measured. Results. The following average measurements for acetabulum geometry were obtained (X ? SD): CEA - 33.5 ? 6.5? (33.6 ? 5.8? in male, 33.3 ? 6.9? in female), AA - 38.0 ? 3.8? (37.5 ? 3.6? in male, 38.5 ? 3.9? in female), AD - 11.9 ? 2.8 mm (12.5 ? 2.7 mm in male, 11.2 ? 2.7 mm in female), ARO - 7.6 ? 5.7? (6.2 ? 4.9? in male, 9.0 ? 6.0? in female) and RA - 18.4 ? 10.0? (19.6 ? 8.5? in male, 17.1 ? 9.5? in female). There were significant differences in the CEA, AA, AD, ARO and RA related to gender (p < 0.01, t-test). Conclusion. There are significant gender differences in Serbian population for all the examined anatomical parameters of acetabulum. We found sex-related differences in acetabular morphology, female acetabulum being marginally more dysplastic than male acetabulum. There is also a clear tendency of female hips to be more dysplastic than male ones.

The aim of this investigation was to examine normal acetabular morphometry, its sex dimorphism and the acetabular dysplasia rate in Serbian adults. For each hip, the centre-edge angle of Wiberg, the acetabular angle of Sharp, acetabular depth and acetabular roof obliquity were measured. The center-edge angle of Wiberg correlated negatively with the acetabular angle of Sharp and acetabular roof obliquity, but positively correlated with acetabular depth. Our results suggest that the prevalence of acetabular dysplasia in the Serbian population is lower than in Western countries. We confirmed the existence of significant gender differences in acetabular morphology among the subjects of our study. These sex-related differences in acetabular morphology were the cause for more dysplastic female acetabula compared with male acetabula.

ABSTRACT To retrospectively analyze the medial space ratio (MSR) of the hip joint to evaluate its efficacy in predicting osteonecrosis of femoral head (ONFH)-induced collapse and its impacts on the mechanical environment of necrotic femoral head. In this retrospective analysis of traditional Chinese medicine, non-traumatic ONFH (NONFH) patients from January 2008 to December 2013 were selected. The patients were divided into collapse group and non-collapse group based on whether the femoral head collapsed. The anatomical parameters including center–edge (CE) angle, sharp angle, acetabular depth ratio and MSR were evaluated. Receiver operating characteristic curves were estimated to evaluate the sensitivity and specificity of MSR and CE angle in collapse prediction. The results showed that 135 patients (151 hips) were included in this study. The differences in CE angle and MSR between collapse group and non-collapse group were statistically significant. The mean survival time of the hips of patients with MSR &lt;20.35 was greater (P &lt; 0.001) than that of patients with MSR &gt;20.35. The ONFH patients with MSR &gt;20.35 were prone to stress concentration. We could conclude that the hip joint MSR and CE angle strongly correlated with the collapse of NONFH. The specificity of MSR is higher than that of CE angle. When MSR is &gt;20.35, the collapse rate of ONFH will increase significantly.

Following the Swiss Federal Office of Public Health (FOPH) authorization of the rapid antigen test (RAT), we implemented the use of the RAT in the emergency ward of our university hospital for patients’ cohorting. RAT triaging in association with RT-PCR allowed us to promptly isolate positive patients and save resources. Among 532 patients, overall sensitivities were 48.3% for Exdia and 41.2% for Standard Q®, PanbioTM and BD Veritor™. All RATs exhibited specificity above 99%. Sensitivity increased to 74.6%, 66.2%, 66.2% and 64.8% for Exdia, Standard Q®, PanbioTM and BD Veritor™, respectively, for viral loads above 105 copies/mL, to 100%, 97.8%, 96.6% and 95.6% for viral loads above 106 copies/mL and 100% for viral loads above 107 copies/mL. Sensitivity was significantly higher for patients with symptoms onset within four days (74.3%, 69.2%, 69.2% and 64%, respectively) versus patients with the evolution of symptoms longer than four days (36.8%, 21.1%, 21.1% and 23.7%, respectively). Among COVID-19 asymptomatic patients, sensitivity was 33%. All Immunoglobulin-A-positive patients resulted negative for RAT. The RAT might represent a useful resource in selected clinical settings as a complementary tool in RT-PCR for rapid patient triaging, but the lower sensitivity, especially in late presenters and COVID-19 asymptomatic subjects, must be taken into account.

The hip joint involvement in multiple hereditary exostoses (MHE) occurs in 30–90%, causing pain and limitation of motion by femoroacetabular impingement, coxa valga, acetabular dysplasia, hip joint subluxation, and osteoarthritis. The purpose of this study was to investigate the clinical and radiographic outcomes of ten hips in seven patients treated by surgical dislocation and corrective osteotomies between 2004 and 2009. Surgical dislocation and excision of the osteochondromas and varus intertrochanteric osteotomies were performed in all cases when the neck–shaft angle was > 150°. Common sites of osteochondromas were medial, posterior, and anterior neck of the femur. Neck–shaft angle of the femur was improved from a mean of 157° to 139°, postoperatively. On an average, the center-edge angle improved from 20° to 30° postoperatively. We believe that Ganz’s safe surgical dislocation technique is the preferred treatment of MHE. This safeguards the circulation of the femoral head and the osteochondromas can be resected under direct vision. It can be combined with additional corrective osteotomies because the hip affected by MHE is frequently associated with dysplastic changes which can result in premature osteoarthritis.

Abstract Purpose The application of the anatomical parameters of the contralateral hip joint to guide the preoperative template of the affected side relies on the bilateral hip symmetry. We investigated the bilateral hip symmetry and range of anatomical variations by measurement and comparison of bilateral hip anatomical parameters. Methods This study included 224 patients (448 hips) who were diagnosed with osteoarthritis (OA) and avascular necrosis (AVN) of the femur head, and underwent bilateral primary total hip arthroplasty (THA) in our hospital from January 2012 to August 2020. Imaging data included 224 patients X-ray and 30 CT data at the end of the cohort. Anatomical parameters, including the acetabular abduction angle and trochanteric height, were measured using the Noble method. Postoperative measurements included stem size, difference of leg length and offset. Results Except for the isthmus width, there were no significant differences in the anatomical morphology of the hip joint. Among the demographic factors, there was a correlation between body weight and NSA. Among various anatomical parameters, a correlation was present between medullary cavity widths of T + 20, T, and T − 20. The difference in the use of stem size is not due to the morphological difference of bilateral medullary cavity, but due to the different of 1- or 2-stage surgery. Conclusion Bilateral symmetry was present among the patients with normal morphology of the hip medullary cavity, theoretically confirming the feasibility of structural reconstruction of the hip joint using the hip joint on the uninjured side. Additionally, the difference in the morphology of the hip medullary cavity is not present in a single plane but is synergistically affected by multiple adjacent planes.

Introduction: Periacetabular osteotomy (PAO) has become a favored treatment for symptomatic acetabular dysplasia worldwide. Nevertheless, the parameters for optimal correction to avoid residual instability or iatrogenic impingement have not been defined. Purpose: The purposes of this study were (1) to assess the ability of PAO to correct femoral head coverage to normal ranges as measured by 3D CT scan and (2) to determine if postoperative radiographic parameters of dysplasia are accurate markers of optimal acetabular correction. Methods: A total of 43 hips (in 38 patients, mean 27.7 years, 88.4% female) were enrolled in this prospective cohort study at minimum 1 year after PAO. Postoperative femoral head coverage was assessed via low-dose CT and compared to normative data of asymptomatic hips from the literature. Anterior (3:00-1:15), lateral (1:00-11:00), and posterior (11:25-9:00) sector coverage was defined by averaging the coverage at 15 minute increments in each zone. Postoperative radiographs were utilized to measure lateral center edge angle (LCEA), anterior wall index (AWI), posterior wall index (PWI), and anterior center edge angle (ACEA). Good correction for each sector was defined as coverage from 1 SD below mean to 2 SD above mean. Results: Postoperatively, the anterior sector was normalized in 84% of hips, lateral sector in 84% of hips, and posterior sector in 86% of hips. Sixty-seven percent of hips were corrected to normative range in all three sectors and 19% were corrected in two sectors (86% in at least two sectors). LCEA and PWI showed the highest correlation with lateral and posterior sector coverage with Pearson’s correlation coefficients of 0.67 and 0.71 (p < 0.001), respectively. Weaker correlations were found between anterior coverage and the AWI and ACEA coverage (-0.16 and 0.15, respectively). Good correction was best correlated with the following target values for acetabular correction: LCEA 28°, AI 1°, AWI 0.37, ACEA 32°, and PWI 1.0. Conclusion: PAO can effectively normalize femoral head coverage compared to normative data. Good correction of each sector coverage ranged from 84-86% of cases. The proposed set of radiographic parameter targets were found to be reliable markers of femoral head coverage.

Introduction: Hereditary transthyretin amyloidosis (ATTR) is an autosomal dominant disease, in which destabilized transthyretin protein misfolds and deposits in tissue leading to organ dysfunction. The most common mutation in the United States, transthyretin valine 122 isoleucine (V122I), primarily affects African Americans and is historically associated with cardiomyopathy phenotype in men. Recent studies have described a mixed V122I phenotype with both cardiomyopathy and polyneuropathy. Sex differences in V122I presentations have yet to be examined. Methods: We identified 38 ATTR patients treated at The Ohio State University with genetic testing demonstrating V122I mutation (31.6% female). Clinical data was analyzed for cardiac and nerve involvement including cardiac biopsy or nuclear pyrophosphate scan, echocardiography - interventricular septal thickness (IVSd), posterior wall thickness (PWd), ejection fraction (EF), and electromyography (EMG). Cohorts were divided by sex. Unpaired t-tests were used to calculate statistics. Asymptomatic patients (n=2) were not included. Results: In women with V122I ATTR, the clinical phenotypes were polyneuropathy (75%) and cardiomyopathy (25%) with symptom onset most often in the fourth or fifth decade of life. In men with V122I ATTR, the most common phenotypes were cardiomyopathy (52%) and mixed cardiomyopathy/polyneuropathy (48%) with symptom onset in the seventh and eighth decades of life. In affected individuals, EMG data revealed generalized neuropathy with reduced or absent sural nerve sensory response. Carpal tunnel syndrome, often due to thickening of the transverse ligament, was more common in men than women (84% versus 36%). Men had significant cardiac differences compared to women with thickened ventricles (IVSd 19.9 mm vs 12.5 mm, p<0.001 and PWd 17.3 mm vs 12.1 mm, p<0.001) and decreased ejection fraction (40% versus 55%, p=0.008). Conclusion: Based on our cohort, female ATTR V122I patients present predominantly with polyneuropathy phenotype at a younger age, and males present with predominantly cardiovascular or mixed phenotype. Recognizing these different sex phenotypes in ATTR V122I will improve diagnosis and treatment of patients.
