Ischiofemoral impingement: an etiology of hip pain: case report

An association between hip pain and quadratus femoris muscle abnormality on magnetic resonance imaging (MRI) with concurrent narrowing of the ischiofemoral space has been reported in the recent literature. This raises the possibility that the muscle damage observed is due to ischiofemoral impingement. This diagnosis has been noted in middle-aged females either with or without a history of trauma or surgery, is a rarely described feature. We report here on a 31-year-old woman who presented with non-traumatic hip pain and evidence of narrowing of the ischiofemoral space and edema in the quadratus femoris. Nonsurgical treatment was administered, which relieved her hip pain. The diagnosis of ischiofemoral impingement should be considered in female patients complaining of hip pain without any other evident cause.A associação entre dor no quadril, anormalidade do músculo quadrado femoral na ressonância magnética (RM) e estreitamento do espaço isquiofemoral tem sido relatada na literatura atual, levantando a possibilidade de que essa lesão muscular seja causada pelo impacto isquiofemoral. Tal diagnóstico foi observado em algumas mulheres de meia-idade com ou sem história de trauma ou cirurgia. Os autores relatam aqui uma mulher de 31 anos de idade, que apresentava dor no quadril sem história de trauma, com evidência de estreitamento do espaço isquiofemoral e edema no músculo quadrado femoral. Foi realizado tratamento não cirúrgico com alívio dos sintomas. O diagnóstico de impacto isquiofemoral deve ser considerado em pacientes do sexo feminino com queixa de dor no quadril sem outra causa evidente.Universidade Federal de São Paulo (UNIFESP), Escola Paulista de Medicina (EPM) Grupo de QuadrilUniversidade Federal de São Paulo (UNIFESP), Escola Paulista de Medicina (EPM) Departamento de Ortopedia e TraumatologiaHospital IFOR Grupo de QuadrilUNIFESP, EPM, Grupo de QuadrilUNIFESP, EPM, Depto. de Ortopedia e TraumatologiaSciEL

Professional Soccer Is Associated With Radiographic Cam And Pincer Hip Morphology

Purpose Femoroacetabular impingement syndrome is characterized by a triad: symptoms, clinical signs and imaging findings. Some individuals, especially athletes, have only imaging alterations. The objective of this study was to evaluate the prevalence of cam and pincer morphology in professional soccer players and to investigate the association between the age at which players start playing competitive soccer and duration of the soccer career with the prevalence of these radiographic findings. Methods The prevalence of cam and pincer morphology in sixty professional adult male soccer players and thirty-two male controls was determined using pelvic anteroposterior radiography. Data were recorded for all hips and correlated with the age at which the players started competitive soccer practice and with the duration of their soccer career. Results The prevalence of morphological FAI in the soccer players was 92.5% versus 28.1% in the controls (p < 0.001). The duration of the soccer career was positively correlated with the alpha angle (p = 0.033) and negatively correlated with the retroversion index (p = 0.009). The age at which competitive play began was inversely correlated with the alpha angle (p < 0.001). Conclusion The study showed a high prevalence of cam and pincer morphology in Brazilian professional soccer players compared with controls. The duration of the soccer career was associated with an increased alpha angle and a decreased retroversion index, and the age at which competitive soccer participation began was negatively associated with alpha angle values.A síndrome do impacto do femoroacetabular é caracterizada pela tríade: sintomas, sinais clínicos e achados de imagem; divide-se nos tipos cam (deformidade femoral), pincer (deformidade acetabular) e misto (combinação de deformidades). Alguns indivíduos, especialmente atletas, possuem apenas alterações de imagem. O objetivo deste estudo foi avaliar a prevalência de morfologias cam e pincer em atletas de futebol profissional e investigar a associação entre a idade em que os atletas começam a jogar futebol competitivo e a duração total da carreira de futebol com a prevalência dos achados radiográficos. Métodos: a prevalência de morfologias cam e pincer em 60 jogadores profissionais de futebol adultos e 32 controles masculinos foi determinada por meio de radiografia anteroposterior da pelve. Os dados foram registrados para todos os quadris e correlacionados com a idade em que os jogadores começaram a prática de futebol competitivo e com a duração de sua carreira no futebol. Resultados: a prevalência de alterações morfológicas cam e pincer nos jogadores de futebol foi de 92,5% contra 28,1% nos controles (p <0,001). A duração da carreira de futebol foi positivamente correlacionada com o ângulo alfa (p = 0,033) e negativamente correlacionada com o índice de retroversão (p = 0,009). A idade de início no esporte competitivo foi inversamente correlacionada com o ângulo alfa (p <0,001). Conclusões: o estudo mostrou alta prevalência de morfologias cam e pincer em jogadores brasileiros de futebol profissional, em comparação com os controles. A duração da carreira de futebol foi associada ao aumento do ângulo alfa e à diminuição do índice de retroversão e a idade de início no esporte foi inversamente associada aos valores do ângulo alfa.Dados abertos - Sucupira - Teses e dissertações (2018

Prevalence of Radiographic Signs of Femoroacetabular Impingement in Asymptomatic Patients and Non-Athletes

Abstract Objective Femoroacetabular impingement has been described as an anatomical variation of the proximal femur and/or acetabular rim, impinging the hip joint. A portion of the population asymptomatic in the hip may present radiographic changes from femoroacetabular impingement. The aim of the present study was to evaluate the prevalence of these signs in asymptomatic and sedentary males. Methods This was a clinical, observational, primary, cross-sectional, controlled study. A total of 32 male volunteers aged between 18 and 40 years, asymptomatic in the hip and sedentary, were selected from a university hospital orthopedic emergency room. All patients underwent standard anteroposterior pelvic radiographs. The measurements of the alpha angle, the retroversion index, the ischial spine signal, and the posterior wall sign were analyzed. Results The mean age was 29 years (18-40 years old). The prevalence of radiographic signs of femoroacetabular impingement using an alpha angle of 67o was of 53.1%; with an alpha angle of 82o, it was of 31.2%. The mean alpha angle was 67o (52.4-88.2o), with 35.9% of the hips classified as borderline and 6.3% as pathological. The mean alpha angle for the right side was 67.5o (52.5-88.2o), and, for the left, it was 66.6o (53.1- 86.9o). The mean retroversion index was 0.048 (right side: 0.044; left side: 0.052). The spine signal was positive in 15.6%, and the posterior wall sign, in 20.3% of the cases. Conclusion This study showed that the prevalence of radiographic signs in a population of asymptomatic and sedentary adult men was high (31.2%). New studies are required to explian the actual clinical significance of this finding

Epidemiological profile of patients diagnosed with athletic pubalgia

ABSTRACT OBJECTIVE: To evaluate the clinical and epidemiological characteristics of pubalgia in patients from a Sports Medicine Center. METHODS: Data analysis from medical records of patients with athletic pubalgia attended to from January 2007 to January 2015. The diagnosis was made by an experienced hip surgeon, complemented with pelvic X-ray, abdominal wall ultrasound, and magnetic resonance imaging of the pelvis. RESULTS: Among 43 patients, 42 were men, with mean age of 33 years. As for sports, 25 (58.1%) athletes were soccer players and 13 (30.2%) were runners; 37.2% were professional athletes. Inguinal hernia was diagnosed in 20.9% of patients, showing the importance of its routine search in these patients. Treatment duration ranged from 1 to 12 months and 95.2% of the patients returned to sport. CONCLUSION: This study presented the epidemiological characteristics of patients diagnosed with athletic pubalgia attended to in a reference medical center and demonstrated the prevalence of this lesion in male patients, soccer players and runners. It also disclosed a high success rate of the nonoperative treatment, and high rate of return to sport after treatment

Gluteal pain in athletes: how should it be investigated and treated?

ABSTRACT Gluteal pain is a frequent symptom in athletes, and defining it etiologically is a challenge for orthopedists. In the present study, using an anatomical approach to the posterior region of the pelvis and the proximal femur, divided into four quadrants, systematized investigation is proposed with the aim of optimizing the treatment and accelerating athletes' return to their sport, through correct diagnosis

RELATIONSHIP BETWEEN PARVOVIRUS B19 AND OSTEOARTHRITIS: LITERATURE REVIEW

ABSTRACT Osteoarthritis and Parvovirus B19 infection present silent and gradual evolution, since the former is a degenerative process while the latter is often asymptomatic and may persist in the individual’s body during their life. This study aims to analyze clinical studies that establish a correlation between degenerative osteoarthritis and Parvovirus B19 infection. Of the 62 studies found, 25 were chosen for reading in full. Analyzing only the studies that establish the correlation between the pathologies, seven confirm this relationship between Parvovirus B19 and Osteoarthritis, while one reports no relationship. No objective correlation could be found between the other articles studied. Our findings suggest that there is a close relationship between Parvovirus B19 and Osteoarthritis, with a higher prevalence of acquired causes, women and older adults, but it can manifest during life. However, it is essential to carry out new studies involving family history of patients with Osteoarthritis with positivity of Parvovirus B19, cohort studies between childhood and adult-old adult, so that it can elucidate this duality of congenital-acquired cause and, finally, raise treatment alternatives.

OBJETIVO: Analisar os métodos mais comuns de medida da altura patelar e o impacto da experiência do observador na correlação com os outros avaliadores utilizando a radiografia digital. MÉTODOS: Sessenta radiografias digitais do joelho na incidência em perfil foram analisadas por quatro observadores, sendo um médico residente do segundo ano de ortopedia (R2), um médico residente do terceiro ano de ortopedia (R3), um ortopedista especialista em joelho (EJ) e um radiologista especialista na área musculoesquelética (ER). Os índices estudados foram: Insall-Salvati (IS), Blackburne-Peel (BP), Caton-Deschamps (CD) e Insall-Salvati modificado (ISM). Foi calculada a concordância interobservadores por meio do coeficiente de concordância Kappa (&#954;). RESULTADOS: Os maiores coeficientes de correlação foram obtidos com o método de IS seguido pelo método de CD. A pior correlação foi observada no método de ISM. A maior concordância interobservadores foi obtida entre o ortopedista especialista em joelho e o radiologista especializado na área musculoesquelética nos quatro métodos de aferição utilizados. CONCLUSÃO: Utilizando a radiografia digital, os índices de Insall-Salvati e Caton-Deschamps apresentaram maior concordância interobservadores, sendo esta também influenciada positivamente pela experiência do observador.<br>OBJECTIVE: To analyze the most common methods for measuring patellar height and the impact of observer experience in correlations with the other observers using digital radiography. METHODS: Sixty digital radiographs of the knee in lateral view were analyzed by four observers: a physician in the second year of medical residence in orthopedics (R2); a physician in the third year of medical residence in orthopedics (R3); an orthopedic surgeon who was a specialist in knee surgery (SK); and a radiologist who was a specialist in musculoskeletal radiology (SR). The indices used were: Insall-Salvati (IS), Blackburne-Peel (BP), Caton-Deschamps (CD) and modified Insall-Salvati (ISM). The interobserver agreement was calculated using the kappa coefficient (k). RESULTS: The highest correlation coefficients were found when using the IS method followed by the CD method. The worst correlation was observed in the ISM method. The highest interobserver agreement was found between the orthopedic surgeon specializing in knee surgery and the radiologist specializing in musculoskeletal radiology, for the four measurement methods used. CONCLUSION: Using digital radiography, the Insall-Salvati and Caton-Deschamps indexes presented the highest interobserver agreement, and this was also positively influenced by the observer's level of experience
