OBJECTIVE:Hip fractures have been associated with increased mortality in the elderly. Several risk factors such as the time between the insult and the surgical repair have been associated with hip fracture mortality. Nevertheless, the risk of delayed surgical repair remains controversial. Few studies have examined this issue in Brazil. The aim of this study was to study the risk factors for death one year after hip fracture and in-hospital stay at a tertiary hospital in South Brazil.METHODS:A prospective cohort study was carried out from April 2005 to April 2011 at a tertiary university hospital at Santa Maria, Brazil. Subjects admitted for hip fracture who were 65 years of age or older were followed for one year. Information about fracture type, age, gender, clinical comorbidities, time to surgery, discharge, and American Society of Anesthesiologists score were recorded. Death was evaluated during the hospital stay and at one year.RESULTS:Four hundred and eighteen subjects were included in the final analysis. Of these, 4.3% died in-hospital and 15.3% were dead at one year. Time to surgery, American Society of Anesthesiologists score, Ischemic Heart Disease, and in-hospital stay were associated with death at one year in the univariate analysis. The American Society of Anesthesiologists score and time to surgery were one-year mortality predictors in the final regression model. In-hospital death was associated with American Society of Anesthesiologists score and age.CONCLUSION:Time to surgery is worryingly high at the South Brazil tertiary public health center studied here. Surgical delay is a risk factor that has the potential to be modified to improve mortality.

Our study established a higher prevalence of radiographic markers of FAI in an asymptomatic population.

In many papers, the diagnosis of pincer-type femoroacetabular impingement (FAI) is attributed to the presence of coxa profunda. However, little is known about the prevalence of coxa profunda in the general population and its clinical relevance. In order to ascertain its prevalence in asymptomatic subjects and whether it is a reliable indicator of pincer-type FAI, we undertook a cross-sectional study between July and December 2013. A total of 226 subjects (452 hips) were initially screened. According to strict inclusion criteria, 129 asymptomatic patients (257 hips) were included in the study. The coxa profunda sign, the crossover sign, the acetabular index (AI) and lateral centre-edge (LCE) angle were measured on the radiographs. The median age of the patients was 36.5 years (28 to 50) and 138 (53.7%) were women. Coxa profunda was present in 199 hips (77.4%). There was a significantly increased prevalence of coxa profunda in women (p < 0.05) and a significant association between coxa profunda and female gender (p < 0.001) (92% vs 60.5%). The crossover sign was seen in 36 hips (14%), an LCE > 40° in 28 hips (10.9%) and an AI < 0º in 79 hips (30.7%). A total of 221 normal hips (79.2%) (normal considering the crossover) had coxa profunda, a total of 229 normal hips (75.5%) (normal considering the LCE) had coxa profunda and a total of 178 normal hips (75.3%) (normal considering AI) had coxa profunda. When the presence of all radiological signs in the same subject was considered, pincer-type FAI was found in only two hips (one subject). We therefore consider that the coxa profunda sign should not be used as a radiological indicator of pincer-type FAI. We consider profunda to be a benign alteration in the morphology of the hip with low prevalence and a lack of association with other radiological markers of FAI. We suggest that the diagnosis of pincer-type FAI should be based on objective measures, in association with clinical findings.

Abstract-Hip osteoarthritis (OA) is a degenerative disease, and total hip arthroplasty (THA) is one of the surgical procedures of choice to improve the OA patient's quality of life. Without a rehabilitation program, THA patients will develop functional limitations. A randomized double-blind trial was performed between July 2009 and October 2011 to compare over a short follow-up time two groups of patients who underwent THA for OA. The THA protocol (THAP) group received verbal instructions and physiotherapy exercise demonstrations, and the THA physiotherapy care protocol (THAPCP) group received the same verbal instructions and demonstrations associated with daily exercise practice guided by a physiotherapist. The outcomes that were assessed preoperatively and 15 d postoperatively in 106 patients were muscle strength force, goniometry, Medical Outcomes Study 36-Item Short Form Health Survey, and Merle d'Aubigné and Postel score. Higher muscle strength force scores and degrees in range of motion were found in the THAPCP group. Greater improvements were also observed for the THAPCP group than the THAP group in the Merle d'Aubigné and Postel score. At the end of the follow-up period, the intervention in the THAPCP group improved functional capacity, quality of life, mobility, muscle strength, goniometry, and pain. It appears to be a safe tool for accelerating recovery in THA patients.Clinical Trial Registration: ClinicalTrials.gov; NCT01491048, "Evaluation of functional rehabilitation in patients undergoing physiotherapy after total hip arthroplasty (arthrosis)"; https://clinicaltrials.gov/ct2/show/NCT01491048
