Validation of the Brazilian version of the Hip Sports Activity Scale (HSAS) for patients with femoroacetabular impingement: a cross-sectional study

ABSTRACT BACKGROUND: The Hip Sports Activity Scale (HSAS) is a hip-specific instrument for assessing the present levels of physical activity among patients with femoroacetabular impingement (FAI) syndrome. When evaluating treatment outcomes in patients with FAI syndrome, it is necessary to use joint-specific instruments and ones that can evaluate the levels of physical activity in these patients, such as the HSAS-Brazil. OBJECTIVE: To validate the HSAS-Brazil among a group of physically active patients after arthroscopic treatment of FAI syndrome. DESIGN AND SETTING: Cross-sectional research of quantitative and qualitative types using data obtained from July 2018 to October 2019. METHODS: A total of 58 patients of both genders diagnosed with FAI syndrome and who had undergone hip arthroscopy participated in this research. To establish reliability and validity, patients first answered the Brazilian versions of the 12-Item Short-Form Health Survey (SF-12), Nonarthritic Hip Score (NAHS), and HSAS; after a 48-hour interval, they answered the HSAS-Brazil again. RESULTS: For test-retest reliability, the interclass correlation was 0.908 (P < 0.001). The HSAS-Brazil correlated to the NAHS-Brazil (r = 0.63, P < 0.001), as well as the SF-12 (Physical Health) (r = 0.42, P = 0.001). CONCLUSION: The HSAS-Brazil was validated and proved to be a reliable and valid scale to assess sports activity levels in physically active patients with FAI syndrome after arthroscopic treatment.

The Brazilian version of the Hip Sports Activity Scale: translation and cross-cultural adaptation

Abstract BACKGROUND: The Hip Sports Activity Scale (HSAS) is a reliable and valid tool for determining the levels of sports activities among patients with femoroacetabular impingement (FAI). OBJECTIVE: To translate and cross-culturally adapt the HSAS to the Brazilian Portuguese language. DESIGN AND SETTING: This was a cross-sectional study conducted at the State University of Rio de Janeiro. METHODS: The Brazilian version of the HSAS was developed following a process that comprised six steps: translation, synthesis, back-translation, review by committee, pretesting and submission of documentation to the developers. The translation phase involved three independent bilingual translators whose mother language was Brazilian Portuguese. The back-translation phase involved three independent translators whose mother language was English. In order to verify comprehension of the questionnaire, 30 undergraduate students in physical education (65% men), with mean age 23.2 years (standard deviation = 6.8), participated in the pre-testing phase. RESULTS: During the translation step, some terms and expressions were changed to obtain cultural equivalence to the original HSAS. In the pre-testing phase, each item of the scale showed a comprehension level of 100%. CONCLUSION: The HSAS was translated from English to the Brazilian Portuguese language and adapted to Brazilian culture. The HSAS validation is ongoing.

Influence of femoral offset on functional capacity of patients with total hip arthroplasty / Influência do offset femoral na capacidade funcional de pacientes com artroplastia total de quadril

ABSTRACT Objective: To correlate vertical (VFO) and horizontal (HFO) femoral offset with hip range of motion (ROM), peak muscle torque (PT), functional, capacity, and lower limb length in patients with total hip arthroplasty (THA). Methods: A cross-sectional case control study, in which 22 individuals (10 men and 12 women) - aged 61 (41-72), and within 23 (10-40) postoperative days - were evaluated for active hip ROM (fleximetry); Isometric PT (portable dynamometer); functional capacity (Timed up and Go test (TUG) and Harris Hip Score questionnaire); lower limb length (measuring tape); and VFO and HFO (radiographs). Results: The operated limb showed a reduction in length (p = 0.006), ROM for abduction (p = 0.001), flexion (p = 0.003), and external rotation (p = 0.003), as well as in all PT (p < 0.05) when compared with the contralateral limb. Moderate correlations were observed between VFO and external rotators (r = 0.487; p = 0.021); HFO and external rotators PT (r = −0.508; p = 0.016); and the difference between the VFO (operated and non-operated limb) and the TUG (r = −0.570; p = 0.006). Conclusion: Changes to the femoral offset seem to influence functional capacity, as well as the movement and external rotators PT of the hips in patients with THA, considering the postoperative period evaluated. Level of Evidence III, Case Control Study.

Lesiones de cadera relacionadas con la actividad deportiva / Sports-Related Hip Injuries

Introducción: Las lesiones de la cadera relacionadas con las actividades deportivas han sido poco abordadas; sin embargo, han ido en aumento y su diagnóstico suele ser difícil o retardado. Incluyen múltiples afecciones y su recuperación suele ser larga. Objetivo: Actualizar conocimientos sobre algunas de las afecciones deportivas que afectan la cadera. Métodos: Se realiza una revisión bibliográfica sistemática y detallada sobre el tema, para lo cual se emplearon métodos teóricos, analítico-sintético, histórico-lógico e inductivo-deductivo y el análisis documental como método empírico. Se hizo una búsqueda sistemática sobre la temática en las bases de datos PubMed, Medscape y Google Academics desde junio de 2016 hasta la fecha. Se revisaron 500 artículos referentes al tema, de los cuales se seleccionaron 45 artículos para este trabajo. Análisis y síntesis de la información: Las lesiones de la cadera relacionadas con el deporte ocurren entre 5 y 9 por ciento de atletas adultos. Las actividades con movimientos rápidos, aceleraciones, desaceleraciones, y los cambios direccionales son la principal causa de tales lesiones. Provocan daños corporales provocados por una transferencia de energía, que excede la capacidad para mantener la estructura y/o la función íntegra, durante el entrenamiento o competición. Conclusiones: Las lesiones de la cadera relacionadas con el deporte pueden ser múltiples y son responsables de dolor en un gran número de atletas, fundamentalmente en el fútbol, la gimnasia y el beisbol. El diagnóstico precoz es fundamental para evitar la progresión de la lesión. Las mejoras en el diagnóstico radiológico y las posibilidades del uso de la artroscopia han mejorado la evolución y el pronóstico para los atletas(AU)

Introduction: Sports injuries of the hip have been little addressed; however, they have been increasing and their diagnosis is often difficult or delayed. They include multiple conditions and their recovery is usually long. Objective: To bring up to date knowledge on some of the sports conditions that affect the hip, which is particularly important to improve medical care. Methods: A systematic and detailed bibliographic review is carried out on the subject, for which theoretical, analytical-synthetic, historical-logical and inductive-deductive methods were used, as well as documentary analysis as an empirical method. A systematic search on the subject was carried out in PubMed, Medscape and Google Academics databases from June 2016 to date. Five hundred articles referring to the topic were reviewed. Forty-five articles the total were selected for this paper. Analysis and synthesis of the information: Sports-related hip injuries occur between 5 and 9 percent of adult athletes. Activities with rapid movements, accelerations, decelerations, and directional changes are the main cause of such injuries. They cause bodily harm produced by a transfer of energy, which exceeds the capacity to maintain the entire structure and, or function, during training or competition. Conclusions: Sports injuries of the hip can be multiple and are responsible for pain in a large number of athletes, mainly in soccer, gymnastics and baseball. Early diagnosis is essential to avoid progression of the lesion. Improvements in radiological diagnosis and the possibilities of the use of arthroscopy have improved the evolution and prognosis for athletes(AU)

Análisis de la mortalidad tras una fractura de cadera en un período de 15 años: la mortalidad al año se correlaciona directamente con la mortalidad a los 2 años / Mortality trend over 15 years in hip fracture: mortality at 1 year directly correlates with mortality at 2 years

OBJETIVO: Evaluar la tendencia de la letalidad al año y a 2 años, tiempo de espera de cirugía y estadía hospitalaria en fractura de cadera entre 2002 y 2016. Además, evaluar la correlación entre letalidad a uno y dos años. MÉTODO: Diseño transversal. Fueron incluidos pacientes mayores de 60 años que ingresaron por fractura de cadera entre 2002 y 2016. Se solicitó al Registro Civil reportar si los pacientes estaban con vida al 30 de junio de 2019. La correlación de Spearman fue estimada para determinar la tendencia de la letalidad a uno y dos años, la edad, el tiempo de espera de cirugía, y la estadía hospitalaria durante el periodo estudiado. Además, una regresión linear fue estimada entre letalidad a un año y dos años. RESULTADOS: Fueron incluidos 961 fracturas de cadera. Se observó una tendencia a la disminución en la letalidad a 1 (rho » -0.23) y 2 años (rho » -0.29), en la proporción de hombres (rho » -0.25), en la estadía hospitalaria (rho » -0.06), y en el tiempo de espera de cirugía (rho » -0.11), sin alcanzar significancia estadística. La letalidad a 1 año fue de 0,17 (intervalo de confianza de 95% [IC95%]: 0,14 a 0,19), y a 2 años, de 0,26 (IC 95%: 0,23 a 0,29). Se estimó un R2 de 0,60 entre la letalidad a 1 y 2 años. CONCLUSIONES: La letalidad a uno y dos años, el tiempo de espera de cirugía, la edad de presentación, y la estadía hospitalaria no han variado significativamente en el periodo estudiado. Se observa una fuerte correlación entre la letalidad a uno y dos años, lo que sugiere un riesgo constante de mortalidad después de una fractura de cadera.

PURPOSE: To evaluate the trend in 1 and 2 years, the fatality rate, the waiting time for surgery, and the length of hospital stay in a single center between 2002 and 2016. Also, to evaluate the relationship between the one-year and two-year fatality rates. METHODS: A cross-sectional study. Patients older than 60 years of age who were admited due to hip fracture between 2002 and 2016 were included. A request was made to the Chilean National Civil Registry to determine if the patients were alive on June 30, 2019. The Spearman correlation was estimated to determine the trend of the one-year and two-year fatality rates, the age, the type of fracture, and the waiting time for surgery. Also, a linear regression analysis was estimated between the one-year and two-year fatality rates. RESULTS: A total of 961 hip fractures were included. From 2002 to 2016, a downward trend was found in the 1-year (rho » -0.23) and 2-year fatality rates (rho » -0.29), in the proportion of male patients (rho » -0.25), in the length of hospital stay (rho » -0.06), and in the waiting time for surgery (rho » -0.11), not reaching statistical difference. The 1-year fatality rate was of 0,17 (95% confidence interval [95%CI]: 0.14 to 0.19) and the 2-year fatality rate was of 0,26 (95%CI: 0.23 to 0.29). An R2 of 0.60 was estimated between the 1-year and 2-year fatality rates. CONCLUSIONS: The one-year and two-year fatality rates, the waiting time for surgery, and the length of hospital stay remained constant during the period analyzed. A strong correlation between the one-year and two-year fatality rates was found, which suggests a constant risk of death after hip fracture.

Arthroscopic labrum reconstruction for femoroacetabular impingement syndrome: 12 cases report / 北京大学学报(医学版)

To investigate the surgical effect of hip arthroscopic labrum reconstruction. A retrospective study was performed on the clinical data of 12 patients who underwent hip arthroscopic labrum reconstruction in our department from September 2017 to February 2021 and were followed up for 5-46 months, with an average of 21.5 months. All the patients had a hip joint space of more than 2 mm, and Tonnis grade less than level Ⅱ. These 12 patients underwent arthroscopic debridement of hyperplastic synovium, femoral head and neck and/or acetabular osteoplasty, and labrum reconstruction using autograft iliotibial band or gracilis tendon. After the surgery, we conducted follow-up and data collection, recorded the satisfaction of the patients and occurrence of complications, as well as the cartilage lesion of hip joint observed under the arthroscopy. We compared the alpha angle of Dunn X-ray film, center-edge angle (CE angle) of AP X-ray film, modified Harris hip score (mHHS score), hip outcome score (HOS), international hip outcome tool 12 score (iHOT12 Score), and visual analogue scale (VAS scale) before and after the arthroscopic operation, to assess clinical symptom relief and joint function recovery. The 12 patients were followed up for 5-46 (21.5±12.8) months. The VAS scale were (5.3±2.5) and (2.5±1.4) before and after the surgery, showing significant decrease (P=0.018). The mHHS score were (60.6±22.2) and (83.1±5.8) before and after the surgery, showing significant increase (P=0.003). The patient satisfaction was high (7.8±2.0) (range: 0-10). None of the 12 patients had serious complications, revision surgery, or total hip replacement at the end of the last follow-up. Autologous tendon transplantation for reconstruction of acetabular labrum under arthroscopy can improve the clinical symptoms and joint function of patients with femoroacetabular impingement (FAI), which is a safe and effective treatment.

Relationship of the Pelvic-Trochanteric Index with greater trochanteric pain syndrome

OBJECTIVES: This study aimed to correlate a higher Pelvic-Trochanteric Index (PTI) with an increased varus of the femoral neck with greater trochanteric pain syndrome (GTPS). The secondary objective was to check whether the pelvic width changes with age. METHODS: A prospective study was conducted to compare female patients diagnosed with GTPS (case group) with asymptomatic female participants (control group) from March 2011 to June 2017. On an anteroposterior pelvic radiograph, lines were drawn by two radiologists, and the PTI (ratio of the distance between the greater trochanters and distance between the iliac crests) was defined and the femoral neck-shaft angle was measured. RESULTS: Data collected based on radiographs of 182 female patients (cases) and 150 female participants (controls) showed that the mean PTI was 1.09 (SD=0.01) in the case group and 1.07 (SD=0.01) in the control group (p<0.05), regardless of age. The distance between iliac crests increased with age (p<0.05) in symptomatic and asymptomatic individuals. It was also found that the mean femoral neck-shaft angle was 130.6° (SD=0.59) and progression of the varus angulation occurred with age in both groups, with a significance level of 5%. CONCLUSIONS: The PTI was higher in patients with GTPS. The femoral neck-shaft angle does not differ between individuals with and without GTPS; however, it does decrease with age. The pelvic width tends to increase with aging in symptomatic or asymptomatic individuals; therefore, the increase in the pelvic width and decrease in the femoral neck-shaft angle can be interpreted as normal in aging women, which could alter the biomechanics of the hips and pelvis.

Comparison between the Dominant and Non-dominant Sides of Athletes with Groin Pain / Comparação funcional entre membro dominante e não dominante em atletas com dor inguinal

Abstract Objective To compare the difference in range of motion (ROM) between the dominant and nondominant hips of the athletes and to correlate the results with groin pain, as well as to compare the differences in ROM among the main hip injuries. Methods The participants included 75 athletes, 56 males and 19 females, aged between 20 and 46 years old, who were diagnosed with hip injury. These individuals were subdivided according to the pathologies (femoroacetabular impact or labral lesion, adductor and pubic lesions and trochanteric syndrome) and characteristics of each hip were analyzed. Results A total of 150 hips (right and left) were measured for the present analysis. When comparing the ROM of the injured hip with the healthy hip, no statistically significant differences were found. There were also no significant differences between the amplitudes of hip movement when the main pathologies were compared. Conclusion The present study did not find differences in ROM rotation between the various pathologies of the hip.

Resumo Objetivo Comparar a diferença do arco de movimento (ADM) entre o quadril com lesão e o não lesionado de atletas com as principais patologias femoroacetabulares. Além disso, analisar a diferença da ADM do quadril em cada patologia considerada. Métodos Os participantes do presente estudo foram 75 atletas de diversas modalidades esportivas, sendo 56 mulheres e 19 homens, com idades entre 20 e 46 anos, os quais tinham diagnóstico de lesão do quadril. Esses indivíduos foram subdivididos em três grupos de acordo com as patologias (impacto femoroacetabular ou lesão labral, pubalgia ou lesão dos adutores e síndrome trocantérica) e as características de cada quadril foram analisadas. Resultados Um total de 150 quadris (direito e esquerdo) foram mensurados para a presente análise. Comparou-se o ADM do quadril lesado e do quadril saudável de cada atleta e não foram encontradas diferenças estatísticas. Da mesma forma, não houve diferença significativa entre a ADM do quadril entre as principais injúrias. Conclusão O presente estudo não encontrou diferenças no arco de movimento entre o quadril lesionado e o contralateral, bem como não houve diferença na amplitude dos movimentos entre as patologias femoroacetabulares analisadas.

Imagenological findings of external snapping hip syndrome. case report

ABSTRACT Introduction: External snapping hip syndrome is characterized by a painful sensation accompanied by an audible snapping noise in the hip when moving. Even though orthopedists are widely aware of this condition, imaging findings still need to be recognized by all radiologists in order to provide more information that allows for the best multidisciplinary treatment. Z-plasty of the iliotibial band is the most used treatment with the best results. Case presentation: Female patient with bilateral external hip snapping syndrome on the right side, who was treated initially in a conservative manner without adequate response; hence, she required surgical management with arthroscopy. All treatment options used for this patient were not successful, and symptoms recurred. Discussion: The diagnosis of snapping hip syndrome is mainly clinical. However, the contribution of diagnostic imaging is important to characterize the structures involved in this nosological process, in order to develop the therapeutic planning and do the follow-up. Conclusion: Knowledge on ultrasound and magnetic resonance findings related to this pathology allows radiologists to identify this syndrome and contribute to a timely treatment.

RESUMEN Introducción. El síndrome de cadera en resorte externa es una entidad en la cual hay una sensación de dolor acompañada de un sonido palpable durante el movimiento de la cadera. Esta es una condición ampliamente conocida por los ortopedistas, pero aún es necesario que los hallazgos imagenológicos sean reconocidos por todos los radiólogos con el fin de brindar mayor información que permita un adecuado manejo multidisciplinario. La Z-plastia de la banda iliotibial es la técnica de tratamiento más reconocida y con mejores resultados. Presentación del caso. Paciente femenino con síndrome de cadera en resorte externo bilateral sintomático en el lado derecho, quien fue manejada de forma conservadora sin adecuada respuesta y requirió manejo quirúrgico por vía artroscópica. Las técnicas utilizadas en la paciente no fueron exitosas y se presentó recurrencia de los síntomas. Discusión. El diagnóstico del síndrome de cadera en resorte es principalmente clínico. Sin embargo, el aporte de las imágenes diagnósticas es importante para caracterizar las estructuras involucradas en este proceso nosológico, para realizar el planeamiento terapéutico y para hacer el seguimiento. Conclusión. Conocer los hallazgos imagenológicos en ultrasonido y resonancia magnética del síndrome en cadera en resorte externa permite a los radiólogos identificarlo y hacer aportes al manejo de esta patología en forma oportuna.

Post-Treatment Classification for Acetabular Chondral Lesions in Hip Arthroscopy / Classificação pós-tratamento para lesões condrais acetabulares na artroscopia de quadril

Abstract Objective To describe a postarthroscopic treatment classification system for acetabular chondral damage in the hip and to report the intraobserver and interobserver reliability of such classification. Methods This is a retrospective review of ninety-nine digital video recordings made during arthroscopic surgery. Patients who underwent arthroscopic treatment for femoroacetabular impingement and evaluated at the hip arthroscopy outpatient clinic between March 2015 and March 2016 were included in the study. Patients with a history of previous hip surgery, radiologic evidence of advanced osteoarthritis (Tönnis grade > 2), who underwent labral resection, or whose digital recordings were incomplete or of insufficient quality for adequate review were excluded. Two orthopedic surgeons, who did not participate in the surgery, independently reviewed the video recordings and classified the remaining acetabular cartilage using the post-treatment classification system. Intraobserver and interobserver analysis was then conducted using intraclass correlation coefficient (ICC). Results Excellent intraobserver reliability (ICC = 0.790; p < 0.001) and interobserver reliability (ICC = 0.882; p < 0.001) were observed. Both ICC values were statistically significant. Conclusion The posttreatment classification of the remaining acetabular cartilage has excellent intra and interobserver reliability.

Resumo Objetivo Descrever um sistema de classificação de tratamento pós-artroscópico para as lesões condrais acetabulares no quadril e relatar as confiabilidades intra e interobservador deste sistema. Métodos Esta é uma revisão retrospectiva de 99 gravações de vídeo digital realizadas durante artroscopia. Os pacientes submetidos a tratamento artroscópico para impacto femoroacetabular e avaliados no ambulatório de quadril entre março de 2015 e março de 2016 foram incluídos no estudo. Os pacientes com histórico de cirurgia anterior do quadril, evidência radiológica de osteoartrose avançada (Tönnis > 2), pacientes submetidos à ressecção labral ou cujas gravações digitais estavam incompletas ou de qualidade insuficiente para avaliação adequada foram excluídos. Dois ortopedistas, que não participaram da cirurgia, revisaram de forma independente as gravações de vídeo e classificaram a cartilagem acetabular remanescente usando o sistema de classificação pós-tratamento. A análise intra e interobservador foi então realizada utilizando o coeficiente de correlação intraclasse (CCI). Resultados Excelente confiabilidade intraobservador (CCI = 0,790; p < 0,001) e confiabilidade interobservador (CCI = 0,882; p < 0,001). Ambos os valores de CCI foram estatisticamente significativos. Conclusão a classificação pós-tratamento da cartilagem acetabular remanescente possui excelente confiabilidade intra e interobservador.

Prevalence of Radiographic Signs of Femoroacetabular Impingement in Asymptomatic Patients and Non-Athletes / Prevalência de sinais radiográficos de impacto femoroacetabular em indivíduos assintomáticos e não atletas

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.

Foram selecionados 32 voluntários masculinos, de 18 a 40 anos, assintomáticos quanto ao quadril, sedentários, atendidos em um Pronto-Socorro de Ortopedia de Hospital Universitário. Todos fizeram radiografias anteroposteriores da pelve padronizadas. Foram analisadas as medidas de ângulo alfa, índice de retroversão, sinal da espinha isquiática e sinal da parede posterior. Resultados A média de idade foi de 29 anos (18-40). A prevalência de sinais radiográficos de impacto femoroacetabular com o uso do ângulo alfa de 67o foi de 53,1%; como ângulo alfa de 82o, essa prevalência foi de 31,2%. A média do ângulo alfa foi de 67o (52,4-88,2o), 35,9% dos quadris foram classificados como limítrofes e 6,3% como patológicos. Amédia do ângulo alfa para o lado direito foi de 67,5o (52,5-88,2o) e para o esquerdo, 66,6o (53,1-86,9o). O índice de retroversão médio foi de 0,048 (lado direito - 0,044 e lado esquerdo - 0,052). O sinal da espinha foi positivo em15,6% e da parede posterior em 20,3%. Conclusão O presente estudo demonstrou que a prevalência de sinais radiográficos numa população de homens adultos, assintomáticos e sedentários foi elevada (31,2%).

Mixed-type femoroacetabular impingement associated with subspine impingement: recognizing the trifocal femoropelvic impingement / Impacto femoroacetabular misto associado a impacto subespinhal: reconhecimento do impacto femoropelvico trifocal

ABSTRACT To describe the arthroscopic surgical technique for subspine impingement (SSI) of the anterior inferior iliac spine (AIIS) associated with mixed type femoroacetabular impingement (FAI), through two standard arthroscopic portals (anterolateral and distal mid-anterior) in two patients with trifocal impingement. The authors report the cases of two young male patients, aged 32 and 36 years old, with trifocal femoropelvic impingement (TFPI). The technique consists of segmental capsulectomy, arthroscopic dissection of the AIIS, partial release of the direct head of the rectus femoris, resection of the AIIS projection with a burr and with fluoroscopic aid, correction of the pincer deformity, repair of the labrum with bioabsorbable anchors, and femoral osteoplasty. Details of the diagnostic workup and of the surgical technique are provided and discussed. In these cases, full range of motion was regained after surgery, as well as complete relief of pain, which was sustained in the last follow-up, one year post-operatively. Radiographs show adequate correction of the deformities in all three impingement sites. Simultaneous correction of the three sites (cam, pincer, and subspinal) provided full relief of symptoms and allowed return to work and sports. The authors propose that when approaching the symptomatic SSI, the possibility of concomitant FAI should always be considered and, in those cases, the approach must be comprehensive.

RESUMO O objetivo deste trabalho foi descrever a abordagem cirúrgica artroscópica do impacto subespinhal (ISE) da espinha ilíaca anteroinferior (EIAI) associado ao impacto femoroacetabular (IFA) misto, por meio de dois portais artroscópicos padrão (anterolateral e medioanterior distal) em pacientes com impacto trifocal. Os autores relatam os casos de dois pacientes do sexo masculino, de 32 e 36 anos, com impacto femoropelvico trifocal (IFPT). A técnica consiste na ressecção segmentar da cápsula, dissecção artroscópica da EIAI com liberação parcial do reto femoral, osteoplastia com ressecção da proeminência com lâmina óssea e auxílio radioscópico, correção do pincer, reparo da lesão condrolabial com âncoras e osteoplastia femoral. Detalhes sobre o diagnóstico e a técnica são apresentados e discutidos. Nos casos operados, foi observada recuperação do arco de movimento normal do quadril e ausência de dor, que se mantiveram por um ano pós-operatório. Radiografias demonstram boa correção dos três focos de impacto em ambos os pacientes. A simultânea correção do IFPT nos seus três componentes (came, pincer e subespinhal) promoveu alívio completo dos sintomas e o retorno ao trabalho e aos esportes. Propõe-se que, na abordagem do ISE sintomático, sempre seja considerada a possibilidade da presença de IFA associado; nesses casos, a abordagem deve ser completa.

Two classifications for surgical wound hematoma after total hip replacement / Duas classificações para hematoma de ferida operatória após artroplastia total do quadril

ABSTRACT Objective: To determine the reliability of two classification methods for wound hematoma after total hip replacement. Methods: This prospective cohort study was conducted on patients who underwent total hip replacement for hip osteoarthritis between May 2014 and April 2015. Epidemiological, surgical, and functional data were assessed. Two experienced hip surgeons evaluated 75 pictures of wounds taken 24 hours after surgery. Both evaluators performed the analysis twice, with a 6-week interval between the two analyses. The subjective classification was divided into four different categories describing the hematoma: absent, mild, moderate, and severe. The objective classification was derived from mathematical calculation of the area of the hematoma using a grid superimposed on a picture of the wound. Results: The subjective classification demonstrated an intra-rater agreement of more than 70%, while kappa values showed poor to moderate inter-rater reliability. The objective classification based on mathematical measurements of the hematoma area was more reliable, with good to excellent intra- and inter-rater reliability. Conclusion: The objective classification demonstrated higher intra- and inter-rater reliability. The classification methods used in this study could serve as a useful instrument for orthopedic surgeons, researchers, and health care providers when assessing wound hematomas after total hip replacement. Level of Evidence II; Development of diagnostic criteria on consecutive patients (with universally applied reference ''gold'' standard).

RESUMO Objetivo: Determinar a confiabilidade de dois métodos de classificação dos hematomas de ferida cirúrgica após artroplastia total do quadril. Métodos: Este estudo prospectivo de coorte foi conduzido em pacientes com osteoartrose do quadril submetidos à artroplastia total do quadril entre maio de 2014 e abril de 2015. Foram analisados dados epidemiológicos, cirúrgicos e funcionais. Dois experientes cirurgiões de quadril avaliaram 75 fotografias de feridas obtidas 24 horas após a cirurgia. Ambos os avaliadores analisaram as fotografias duas vezes, em intervalo de seis semanas. A classificação subjetiva consistiu em quatro categorias descrevendo o hematoma: ausente, leve, moderado e grave. A classificação objetiva foi obtida pelo cálculo matemático da área do hematoma, sobrepondo-se uma retícula a cada fotografia de ferida. Resultados: A classificação subjetiva mostrou concordância intra-avaliador de mais de 70%, enquanto que os valores de kappa mostraram concordância inter-avaliador baixa a moderada. A classificação objetiva baseada em cálculo matemático da área do hematoma foi mais confiável, com excelente concordância intra e inter- avaliador. Conclusão: A classificação objetiva demonstrou melhor concordância intra e inter-avaliador. Os métodos de classificação usados neste estudo podem ser um instrumento útil para cirurgiões ortopedistas, pesquisadores e profissionais de saúde para avaliar hematomas de feridas cirúrgicas após artroplastia total de quadril. Nível de Evidência II; Desenvolvimento de critérios diagnósticos em pacientes consecutivos (com padrão de referência "ouro" aplicado).

Research progress in complications of hip arthroscopy / 中华创伤杂志

Hip arthroscopy has become a routine treatment for the localized hip lesions.With the rapid development of arthroscopy,the number of surgeries has increased greatly.Though hip arthroscopy is considered as low risk operation,its complications have been constantly reported and noted.There are two major types in hip arthroscopy surgeries:conventional operative complications and special complications.Conventional operative complications include venous thromboembolism,hemorrhage,and pain.Special complications are associated with arthroscopic techniques and local anatomical structures of the hip,such as the perineal nerve,the lateral femoral cutaneous nerve,the acetabular labium or the iatrogenic injury of the cartilage surface of the femoral head.Hip arthroscopy has obvious advantages such as small surgical wound and rapid recovery,but its complications can not be ignored.Joint surgeons must fully recognize it and keep vigilant so as to avoid complications as much as possible.This review will systematically elaborate the complications of hip arthroscopic surgery from general and special aspects so as to provide ideas for reducing the occurrence of complications in hip arthroscopic surgery.

Application of a novel acetabulum anatomic locking plate in treatment of anterior wall and anterior column acetabular fractures / 中华创伤杂志

Objective To investigate the clinical efficacy of a novel acetabulum anatomic locking plate in the treatment of anterior wall and anterior column acetabular fracture.Methods A retrospective case series study was performed in five patients with anterior wall and anterior column acetabular fractures managed operatively using a novel acetabulum anatomic locking plate from March 2014 to January 2016.There were four males and one female,with an average age of 41.1 years (range,25-65 years).The mean time from injury to operation was 3.2 days (range,2-5 days).All patients were managed operatively using the superior ilioinguinal approach.Operation duration,intraoperative blood loss,blood transfusion,and bony union time were recorded.The image results by Matta standard were evaluated and the acetabular function after operation was assessed by modified Merle d'Aubigné-Postel.Postoperative complications were recorded.Results All patients were followed up for average 15.3 months (range,12-24 months).The average operation duration was 96 minutes (range,60-130 minutes) and average blood loss was 230 ml (range,100-800 ml).Autologous blood transfusion was selectively used except for one patient with allogeneic blood transfusion of 400 ml.The mean time of bony union was 2.9 months (range,2-5 months).According to the Matta criteria,four patients attained anatomical reduction,and unsatisfactory reduction was reported in one patient.Clinical outcomes (Merled'Aubigné-Postel) at 12 months were 100％ excellent with the average score of 17.1 (range,15-18).One patient had a lateral cutaneous nerve palsy,and symptom relief was seen after a follow up of 6 months.After operation,no complications such as surgical site infection,femoral head avascular necrosis,andtraumatic arthritis occurred in any patient.Conclusion The novel acetabulum anatomic locking platecan provide rigid and firm fixation for both anterior wall and anterior acetabular fractures using one singleplate,and the fracture reduction and function recovery are satisfactory.

Fall behaviors and risk factors among elderly patients with hip fractures

Abstract Objective The aim of this study was to investigate fall preventive behaviors in elderly patients who suffered hip fractures as a result of falling. Methods This descriptive and cross-sectional study was performed at a university hospital in Izmir, Turkey between January 2014 and December 2015. Data were collected using the Fall Behaviors Scale for Old People. This study was conducted with 103 patients who had a hip fracture caused by falling. Descriptive statistics, Mann Whitney U and Kruskal-Wallis tests were used. Results There was a significant difference between age groups in this score (KW = 6.85, p = 0.03). The patients aged 85-96 years obtained significantly higher scores for the sub-scales of protective mobility (KW = 8.71, p = 0.01) and avoidance (KW = 6.03, p = 0.04) than patients in the other age groups. There was not a significant difference in fall prevention behaviors between the elderly with a history of a repeated falls and those without a repeated fall history. Conclusion Although elderly people with hip fractures due to falling has highly protective behavior, they have fallen. Advanced age patient has showed more protective behavior for falling.

Open versus arthroscopic approach in the treatment of femoroacetabular impingement: a case-control study with two-years follow up / Abordagem anterior aberta versus artroscópica no tratamento do impacto femoroacetabular: estudo caso-controle com seguimento mínimo de dois anos

Abstract Objective To compare clinical and imaging results and complications between patients treated for femoroacetabular impingement (FAI) who underwent either anterior open surgery or an arthroscopic approach, with a minimum follow-up of two years. Methods This retrospective case-control study included patients submitted to FAI surgical treatment between November 2007 and March 2012. Patients treated with open surgery were compared with those treated with arthroscopy. Patients were clinically assessed by the modified Harris Hip Score, Non-Arthritic Hip Score, and internal hip rotation. Patients were radiographically assessed by the center-edge angle, joint space width, alpha angle, neck-head index, degree of arthrosis, and presence of heterotopic ossification of the hip. Results In the study period, 56 patients (58 hips) with FAI were included; 16 underwent open surgery and 40 underwent arthroscopy. The 40 patients treated by the arthroscopic route had a mean follow-up of 29.1 months, and 75.6% presented good or excellent clinical results. The radiographic evaluation parameters progressed to normal levels. The 16 patients who underwent open surgery had a mean follow-up of 52 months, and 70.58% presented good or excellent clinical results. The radiographic evaluation parameters progressed to normal levels. Postoperative clinical and radiographic results were considered similar in both groups. Conclusions Arthroscopy and open surgery treatments for FAI provided comparable clinical and radiographic results. However, a higher rate of complications was observed in the open surgery group.

Quanto à avaliação radiográfica, observou-se correção para índices considerados normais. Os resultados clínicos e radiográficos pós-operatórios foram considerados semelhantes em ambos os grupos. Conclusão Os resultados clínicos e radiográficos do tratamento artroscópico do impacto femoroacetabular foram comparáveis aos resultados do tratamento aberto. Observamos um maior número de complicações no grupo aberto.

Acute Isolated Tear of Gluteus Medius in Young Male / 대한고관절학회지

The hip rotator cuff tear usually develops in the middle-aged through gradual degenerative changes, similar to rotator cuff tears in the shoulder. An acute tear in the hip abductor by a traumatic event in young ages is very uncommon. The authors experienced an unusual case of an acute traumatic tear isolated to the gluteus medius in a young male; thus, we report the treatment results in this rare case with a review of the literature.
