Anatomic study of the proximal third of the femur: femoroacetabular impact and the cam effect

OBJECTIVE: to analyze anatomical variations of the proximal end of femur that could cause a femoroacetabular impact. METHODS: 199 skeletically mature anatomical specimens of femurs were used. The femurs were measured in order to determine the anteversion angle of the femoral neck, neckshaft angle, sphericity of the femoral head at anteroposterior and superoinferior, angle between epiphysis and the anterior femoral neck, angle between epiphysis and the neck at lateral plane, anteroposterior distance at 5mm of the head and neck junction and anteroposterior distance of the neck base. RESULTS: we found that the impact subgroup presented a significantly larger junction diameter of 5mm (p = 0.0001) and cam-head (%) (p= 0.0001), while base-cam (%) (p = 0.0001) showed a significantly smaller diameter than the subgroup without impact. It was identified that cam-head (%) > 80 e base-cam (%) 80 e base-cam (%) < 73 foram os pontos ótimos para o impacto. CONCLUSÃO: O estudo mostrou que o efeito cam, causado por variações anatômicas da extremidade proximal do fêmur, se concentrou na junção cabeça-colo e base do colo-junção cabeça-colo. Esses índices podem ser fatores preditivos do impacto.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Hospital Santa TeresaHospital Santa Teresa Grupo de Quadril do Serviço de Ortopedia e Traumatologia do Prof. Dr. Donato D'ÂngeloHospital Santa Teresa Serviço de Ortopedia e Traumatologia do Prof. Dr. Donato D'ÂngeloInstituto Nacional de Traumatologia Ortopedia Grupo de Cirurgia do QuadrilUNIFESP, EPM, Hospital Santa TeresaSciEL

The results showed that there was no relationship between age and the incidence of service cancer in the hospital with a p-value of 0.099 (p&gt; 0.05), on the education variable (p-value = 0.003), occupation (p-value = 0.030), parity. (p-value = 0.013), knowledge (p-value = 0.007). In conclusion, there is a significant relationship between education, occupation, parity, and knowledge of respondents with the incidence of cervical cancer in the hospital. &nbsp; Keywords: Reproductive Health, Knowledge, Health Promotio

Trauma consultations in a Swiss tertiary emergency department: Comparison of asylum seekers and the local population—Patient characteristics and patterns of injuries, a retrospective study

BACKGROUND: In 2017, accidents and other acts of violence were the fifth most common cause of death in Switzerland. Moreover, there are increasing numbers of refugees and asylum seekers (AS), who often exhibit distinct disease profiles from those of the natives of the host country. If these differences could be clearly identified, this might help to develop and implement strategies to prevent injuries in health care programs for refugees and asylum seekers. The aim of this study was to examine the types and characteristics of physical trauma profiles in patients from the two largest groups of AS in Switzerland–from Eastern Africa (EA) and the Middle East (ME)–who consulted a Swiss Emergency Department (ED) in 2017/2018. Furthermore, the physical trauma profiles of Swiss national (SN) patients were examined in order to explore potential differences. METHODS: Descriptive retrospective study of adult trauma patients consulting the ED of a Swiss University Hospital between 01/2017 and 12/2018. The study included 157 asylum seeking trauma patients from EA and ME were included in the study. These were matched by gender and age to 157 Swiss trauma patients consulting the ED in the study period. RESULTS: There were significant differences between the groups with respect to type of admission, level of severity, localization and mechanisms of injury. While SN had higher levels of injuries related to road traffic or work, AS had higher levels of injuries related to attempted suicide or to assault. CONCLUSIONS: There were differences between AS and the local population with respect to the characteristics and patterns of injury, so that strategies for preventing injuries and promoting health must be tailored to the target population. Moreover, the observed high rates of outpatient treatment for both groups underline the increasing role of EDs as primary care providers for the population served

Skeletal immaturity, rostral sparing, and disparate hip morphologies as biomechanical causes for Legg-Calvé-Perthes’ disease

Legg-Calvé-Perthes' (Perthes') disease is a developmental disease of the hip joint that may result in numerous short and long term problems. The etiology of the disease remains largely unknown, but the mechanism is believed to be vascular and/or biomechanical in nature. There are several anatomical characteristics that tend to be prevalent in children with Perthes' disease, namely: skeletal immaturity, reduced height, and rostral sparing. We present an overview of the literature, summarizing the current understanding of the pathogenesis, particularly related to how the formation of the vasculature to the femoral epiphysis places children aged 5–8 at a higher risk for Perthes' disease, how skeletal immaturity and rostral sparing could increase the probability of developing Perthes' disease, and how animal models have aided our understanding of the disease. In doing so, we also explore why Perthes' disease is correlated to latitude, with populations at higher latitudes having higher incidence rates than populations closer to the Equator. Finally, we present five hypotheses detailing how Perthes' disease could have a biomechanical cause. Clin. Anat. 29:759–772, 2016. © 2016 Wiley Periodicals, Inc

Accuracy of magnetic resonance studies in the detection of chondral and labral lesions in femoroacetabular impingement : systematic review and meta-analysis

Background: Several types of Magnetic resonance imaging (MRI) are commonly used in imaging of femoroacetabular impingement (FAI), however till now there are no clear protocols and recommendations for each type. The aim of this meta-analysis is to detect the accuracy of conventional magnetic resonance imaging (cMRI), direct magnetic resonance arthrography (dMRA) and indirect magnetic resonance arthrography (iMRA) in the diagnosis of chondral and labral lesions in femoroacetabular impingement (FAI). Methods: A literature search was finalized on the 17th of May 2016 to collect all studies identifying the accuracy of cMRI, dMRA and iMRA in diagnosing chondral and labral lesions associated with FAI using surgical results (arthroscopic or open) as a reference test. Pooled sensitivity and specificity with 95% confidence intervals using a random-effects meta-analysis for MRI, dMRA and iMRA were calculated also area under receiver operating characteristic (ROC) curve (AUC) was retrieved whenever possible where AUC is equivocal to diagnostic accuracy. Results: The search yielded 192 publications which were reviewed according inclusion and exclusion criteria then 21 studies fulfilled the eligibility criteria for the qualitative analysis with a total number of 828 cases, lastly 12 studies were included in the quantitative meta-analysis. Meta-analysis showed that as regard labral lesions the pooled sensitivity, specificity and AUC for cMRI were 0.864, 0.833 and 0.88 and for dMRA were 0.91, 0.58 and 0.92. While in chondral lesions the pooled sensitivity, specificity and AUC for cMRI were 0.76, 0.72 and 0.75 and for dMRA were 0.75, 0.79 and 0.83, while for iMRA were sensitivity of 0.722 and specificity of 0.917. Conclusions: The present meta-analysis showed that the diagnostic test accuracy was superior for dMRA when compared with cMRI for detection of labral and chondral lesions. The diagnostic test accuracy was superior for labral lesions when compared with chondral lesions in both cMRI and dMRA. Promising results are obtained concerning iMRA but further studies still needed to fully assess its diagnostic accuracy

Optimum positioning for AP pelvis radiography : a literature review

Aim Pelvic radiography is used for the identification of hip joint changes, including pathologies such as osteoarthritis. Several studies have recommended that the position for this radiological procedure should be standing, not supine, to reflect the functional appearances of the hip joint. The aim of this review was to evaluate pelvis radiography positioning with respect to the image appearances and information provided for clinical decision-making. Aside from this, potential recommendations to the radiographic technique for an erect pelvis projection will be considered. Method A literature search was performed using databases/abstract systems (ScienceDirect, Web of Science, PubMed, and MEDLINE). Only articles written in English were included. Results Twenty-five articles were identified. Findings from the review describe the effect of repositioning from supine to erect on a series of specific hip measurements. These include pelvic tilt, joint space width, and the acetabular component. Conclusion Evidence within the literature illustrates that in several studies, there were differences when repositioning from supine to standing for a number of pelvic metrics. Standing positioning is promoted by some authors since this may facilitate the early diagnosis of hip joint pathology and assist in the planning of surgical interventions. Literature is very limited on how to optimally perform erect pelvis radiography, and this should be an area for future research
