Avaliação dos métodos de mensuração da altura patelar na radiografia digital

ABSTRACT 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 (κ). 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.

Impacto isquiofemoral: uma etiologia de quadril doloroso: relato de caso

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.

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

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.

Frouxidão ligamentar e pé plano em crianças normais

Objective: To study the correlation between flatfoot and joint laxity in healthy children. Methods: We evaluated 328 children with ages between 3 to 15 years, with no previous musculoskeletal complaints. We classified them by the presence of joint laxity according to the Beighton and Horan criteria, and by the presence of flatfoot according to the Valenti classification. The data obtained werecorrelated with gender, age, ethnic group, and dominant side. Fishers exact test and chi-square test were applied to analyze theresults. Results: A percentage of 83.9% ofindividuals with joint laxity was observed in children younger than 7 years of age (p < 0.001*). There is a significant association between joint laxity and gender (p = 0.025*), as girlsexhibited a greater percentage of laxity (51.02%). We observed a significant association between joint laxity and type of foot (p =0.003*), since the flatfooted group presented a higher percentage of laxity (54.96%). Flatfoot was also associated to joint laxity when we considered only the males (p = 0.001*), which was not observed in the females group. Conclusion: In the population studied, joint laxity was more frequently observed in children younger than 7 years of age, in females, and in individuals with flatfoot. There was no association between joint laxity and ethnic group or dominant side.

A cirurgia precoce nas fraturas do fêmur proximal em idosos reduz a taxa de mortalidade

Objective  To analyze whether a reduction in the waiting time for orthopedic surgery in elderly patients with fracture of the proximal end of the femur leads to a reduction in in-hospital mortality, 6-month mortality, and duration of hospitalization. Methods  This was a retrospective cohort study including 81 patients with intertrochanteric and subtrochanteric fractures who underwent surgical repair between 2015 and 2016 in a referral hospital, before and after a protocol for early surgical fixation (< 48 hours) was implemented. Results  The mean length of hospital stay decreased from 17 to 11 days. Regarding the in-hospital mortality rate, five patients died before, and another five died after the protocol was implemented. The 6-month postoperative mortality decreased from 26.7% to 19.4%. The results showed no statistical significance. Conclusion  The present study demonstrated that there is a tendency to reduce the length of hospital stay and 6-month mortality when the surgery for the treatment of proximal femoral fractures in the elderly is performed within 48 hours of hospitalization.

Prevalência de sinais radiográficos de impacto femoroacetabular em indivíduos assintomáticos e não atletas

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 67 o was of 53.1%; with an alpha angle of 82 o , it was of 31.2%. The mean alpha angle was 67 o (52.4-88.2 o ), with 35.9% of the hips classified as borderline and 6.3% as pathological. The mean alpha angle for the right side was 67.5 o (52.5-88.2 o ), and, for the left, it was 66.6 o (53.1-86.9 o ). 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.

Professional soccer is associated with radiographic cam and pincer hip morphology

PurposeFemoroacetabular impingement (FAI) 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 compared with a control group of non-athletes and to investigate the association between the age at which players start playing competitive soccer more than three times per week and duration of the soccer career with the prevalence of these radiographic findings.MethodsThe 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.ResultsThe 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).ConclusionThe 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. Finally, this manuscript provides data about the association between greater exposure to soccer and cam and pincer morphological changes in the hip; specifically, cam morphology was more common in patients who began participating in sports at earlier ages. This information serves as an alert for coaches of youth teams to manage the training load in youth athletes.Level of evidenceIII.
