Chondral defects in the athlete's hip are a relatively common occurrence, often presenting with debilitating pain and activity limitation. Preoperative identification of cartilage defects is challenging and there are many different modalities for treatment. Nonsurgical interventions, including activity modification, physical therapy, and injections, play a vital role, especially in less severe cases and as adjuncts to surgical intervention. Treating surgeons must be familiar with the cartilage restoration procedures available, including debridement, microfracture, and various implantation and transplantation options. Safe and effective management of cartilage defects is imperative to an athlete's return to sport. It is also imperative that surgeons are aware of all these various treatment options to determine what modality is best for their patients. This review serves to outline these options, cover the published literature, and provide general guidelines for surgeons when they encounter chondral defects in the office and the operating room.

The purpose of the study is to examine whether the physical examination technique, Myrick The Hip Internal Rotation with Distraction (THIRD), is reliable and valid. The Myrick THIRD test has previously established and documented sensitivity, specificity, positive predictive value, and internal and external validity. The goal of this original research was to demonstrate stability reliability of the Myrick THIRD test when the study is conducted in a clinical setting where the test has not previously been performed, as well as to demonstrate that the Myrick THIRD test has external validity when conducted across multiple examiners in a new setting. The importance of the study reflects current clinical practice and the lack of specific clinical assessment techniques used to determine the source of intra-articular hip pain successfully. Testing included the Myrick THIRD test, magnetic resonance arthrogram (MRA), and arthroscopy. The primary outcomes included the results of the MRA, magnetic resonance imaging (MRI), Myrick THIRD test, and arthroscopy. The inclusion criteria were 18- to 49-year-olds presenting with hip pain. The exclusion criteria included patients younger than 18 and older than 49 years and patients who were willing to undergo MRI arthrogram. A test of paired proportions, correlation, sensitivity, and specificity was performed. The significance level was preset at .05. All 86 patients had a positive Myrick THIRD test, which was confirmed with arthroscopy. Eight of the 11 positive MRI results and 64 of the 74 positive MRA results were confirmed with arthroscopy. The Myrick THIRD test had a statistically significant higher accuracy rate than the MRA (p = .002) but not the MRI (p = .08). Myrick THIRD test showed a significantly higher accuracy rate than MRA.

Objetivo: Determinar o perfil epidemiológico de pacientes atendidos pelo Sistema Único de Saúde (SUS), em determinado município do interior de Minas Gerais, bem como os gastos financeiros e o repasse financeiro para os centros de atendimento de traumas. Material e métodos: Trata-se de um estudo ecológico, descritivo, realizado a partir da coleta de dados pelo SIH-SUS, no período de janeiro de 2011 a dezembro de 2021, em um município do interior de Minas Gerais. Resultados: Foi identificado um total de 14.138 pacientes, com maior acometimento de pessoas do sexo masculino, com idade entre 15 e 44 anos. Como causas mais frequentes, destacaram-se os traumatismos de quadril e coxa, seguidos de traumatismos de membros superiores (ombro, antebraço, braço, punho e mão) e cabeça. Como tempo médio de permanência hospitalar, houve 4.693 diárias entre 2011 e 2021 secundárias a complicações em enfermarias e unidade de terapia intensiva, elevando cerca de 2,37% os valores repassados pelo SUS no período estudado. Em resumo, a análise da incidência de traumas nas emergências de um município do interior de Minas Gerais revela uma preocupante tendência em que homens na faixa etária de 15 a 44 anos emergem como as principais vítimas. Esse padrão pode ser influenciado por fatores como ocupação, comportamentos de risco e mobilidade. Conclusão: A compreensão dessa demografia específica é crucial para direcionar estratégias de prevenção e resposta adequadas. A implementação de medidas educativas, segurança no trânsito e promoção da saúde mental pode contribuir para mitigar os impactos dos traumas nesse grupo demográfico, melhorando sua qualidade de vida e a saúde geral da comunidade.
Objective: To determine the epidemiological profile of patients assisted by the unified health system, in a certain municipality in the interior of Minas Gerais, as well as the financial expenses and the financial transfer to trauma care centers. Material and methods: This is an ecological, descriptive study, carried out from data collection by SIH-SUS, from January 2011 to December 2021 in a municipality in the interior of Minas Gerais. Results: a total of 14,138 patients were identified, with greater involvement of male people aged between 15 and 44 years. As the most frequent causes, trauma to the hip and thigh stood out, followed by trauma to the upper limbs (shoulder, forearm, arm, wrist and hand) and head. As for the average length of hospital stay, there were 4,693 daily stays between 2011 and 2021 secondary to complications in wards and the intensive care unit. Increasing about 2.37% in the values transferred by the unified health system between the studied decade. In summary, the analysis of the incidence of trauma in emergencies in a municipality in the interior of Minas Gerais reveals a worrying trend in which men aged 15 to 44 years emerge as the main victims. This pattern can be influenced by factors such as occupation, risky behavior and mobility. Conclusion: Understanding this specific demographic is crucial to targeting appropriate prevention and response strategies. The implementation of educational measures, road safety and mental health promotion can help to mitigate the impacts of trauma in this demographic group, improving their quality of life and the general health of the community.

The hip is a uniquely constrained joint with critical static stability provided by the labrum, capsule and capsular ligaments, and ligamentum teres. The labrum is a fibrocartilaginous structure along the acetabular rim that encircles most of the femoral head. Labral tears are localized based on the clock-face method, which determines the extent of the tear while providing consistent terminology for reporting. Normal labral variants can mimic labral disease and can be differentiated by assessment of thickness or width, shape, borders, location, and associated abnormalities. The Lage and Czerny classification systems are currently the most well-known arthroscopic and imaging systems, respectively. Femoroacetabular impingement is a risk factor for development of labral tears and is classified according to bone dysmorphisms of the femur ("cam") or acetabulum ("pincer") or combinations of both (mixed). The capsule consists of longitudinal fibers reinforced by ligaments (iliofemoral, pubofemoral, ischiofemoral) and circular fibers. Capsular injuries occur secondary to hip dislocation or iatrogenically after capsulotomy. Capsular repair improves hip stability at the expense of capsular overtightening and inadvertent chondral injury. The ligamentum teres is situated between the acetabular notch and the fovea of the femoral head. Initially considered to be inconsequential, recent studies have recognized its role in hip rotational stability. Existing classification systems of ligamentum teres tears account for injury mechanism, arthroscopic findings, and treatment options. Injuries to the labrum, capsule, and ligamentum teres are implicated in symptoms of hip instability. The authors discuss the labrum, capsule, and ligamentum teres, highlighting their anatomy, pathologic conditions, MRI features, and postoperative appearance. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

BACKGROUND: A small proportion of the older population accounts for a high proportion of healthcare use. For effective use of limited healthcare resources, it is important to identify the group with greatest needs. The aim of this study was to explore frequency and reason for hospitalisation and cumulative mortality, in an older population at predicted high risk of hospital admission, and to assess if a prediction model can be used to identify individuals with the greatest healthcare needs. Furthermore, discharge diagnoses were explored to investigate if they can be used as basis for specific interventions in the high-risk group. METHODS: All residents, 75 years or older, living in Östergötland, Sweden, on January 1st, 2017, were included. Healthcare data from 2016 was gathered and used by a validated prediction model to create risk scores for hospital admission. The population was then divided into groups by percentiles of risk. Using healthcare data from 2017-2018, two-year cumulative incidence of hospitalisation was analysed using Gray´s test. Cumulative mortality was analysed with the Kaplan-Meier method and primary discharge diagnoses were analysed with standardised residuals. RESULTS: Forty thousand six hundred eighteen individuals were identified (mean age 82 years, 57.8% women). The cumulative incidence of hospitalisation increased with increasing risk of hospital admission (24% for percentiles < 60 to 66% for percentiles 95-100). The cumulative mortality also increased with increasing risk (7% for percentiles < 60 to 43% for percentiles 95-100). The most frequent primary discharge diagnoses for the population were heart diseases, respiratory infections, and hip injuries. The incidence was significantly higher for heart diseases and respiratory infections and significantly lower for hip injuries, for the population with the highest risk of hospital admission (percentiles 85-100). CONCLUSIONS: Individuals 75 years or older, with high risk of hospital admission, were demonstrated to have considerable higher cumulative mortality as well as incidence of hospitalisation. The results support the use of the prediction model to direct resources towards individuals with highest risk scores, and thus, likely the greatest care needs. There were only small differences in discharge diagnoses between the risk groups, indicating that interventions to reduce hospitalisations should be personalised.

OBJECTIVE: Between 2010 and 2020, an annual average of more than 70,000 pedestrians were injured in U.S. motor vehicle crashes. Pedestrian fatalities increased steadily over that period, outpacing increases in vehicle occupant fatalities. Strategies for reducing pedestrian injuries include pedestrian crash prevention and improved vehicle design for protection of pedestrians in the crashes that cannot be prevented. This study focuses on understanding trends in injuries sustained in U.S. pedestrian crashes to inform continuing efforts to improve pedestrian crash protection in passenger vehicles. METHODS: More than 160,000 adult pedestrians injured in motor vehicle crashes who were admitted to U.S. trauma centers between 2007 and 2016 were drawn from the National Trauma Data Bank (NTDB) Research Data Sets. The injuries in those cases were used to explore the shifting patterns of pedestrian injuries. RESULTS: The proportion of pedestrians with thorax injuries increased 3.0 percentage points to 30.7% of trauma center-admitted NTDB pedestrian cases over the 10 years studied, and the proportion with pelvis/hip injuries increased to 21.2%. The proportion of cases with head injuries fell to 48.6%, and the percentage of pedestrians with lower extremity injury (44%) did not change significantly over the 10 year period. Assessment of possible reasons for the shifts suggested that increasing numbers of sport utility vehicles, population increases among the oldest age groups, and improvements in pedestrian protection in U.S. passenger vehicles likely contributed to, but did not completely account for, the relative changes in injury frequency in each body region. CONCLUSIONS: More important than the reasons for the shifts in the relative frequency of injury to each body region are the conclusions that can be drawn regarding priorities for pedestrian protection research. Though head/face and lower extremity injuries remained the most frequently injured body regions in adult pedestrians admitted to NTDB trauma centers, the relative frequency of thorax and pelvis/hip injuries increased steadily, underlining the increasing importance of pedestrian protection research on these body regions.

Not all acetabular labral tears, tissue quality, and size are the same. There is still a role for selective debridement of the acetabular labrum when stable, functional labral tissue remains. An unstable labrum that appears very different than the rest of the labrum is an easy target for repair. Tears requiring resection require graft augmentation or reconstruction.

PURPOSE: A "floating hip" (FH) injury is a rare injury describing the simultaneous ipsilateral fracture of the femur and pelvis or acetabulum (P/A). We describe our experience with patients presenting with FH injuries and compare them to controls with similar P/A fractures but without femoral involvement. METHODS: Medical records and radiographs of FH patients and controls presenting to our tertiary centre between 2015 and 2020 were reviewed. Follow-up data from outpatient clinical records were also extracted. The control group were extensively matched by age, sex, body mass index, fracture classification and energy of injury. RESULTS: From 1392 recorded P/A fractures, 42 FH cases were identified (average age 39 years, 78.6% males). The most common femoral fracture was the midshaft (35.7%), followed by the neck of femur (26.2%). 90.5% of FH injuries were due to high-energy mechanisms. 64.3% of P/A fractures, and 100% of femoral fractures were managed surgically. Compared to controls, FH cases were more likely to have additional orthopaedic injuries (73.8% vs. 40.5%, p = 0.002), more total theatre admissions (mean 2.5 vs. 1.19, p < 0.001), longer hospital stays (28.3 vs. 14.9 days, p = 0.02), and a higher rates of post-op complications (53.8% vs. 20%, p = 0.025). CONCLUSIONS: We report differences in the presentation, management, and outcomes of FH injuries versus controls, even after extensive matching for confounders. These differences may inform future treatment strategies for the FH injury.

OBJECTIVES: To describe and compare seasonal prevalence, anatomical location, severity, and onset of injuries between female and male elite ice hockey players. DESIGN: Cross-sectional survey study. SETTING: Elite ice hockey. PARTICIPANTS: Swedish elite ice hockey players (170 females & 190 males). MAIN OUTCOME MEASURES: Past season injuries reported on a modified version of the Oslo Sports Trauma Research Center overuse injury questionnaire. Proportions of players who experienced any and substantial problems, as well as respective injury severity scores were presented and compared between sexes. RESULTS: Highest seasonal prevalence was reported for hip/groin [31.1% (n = 112)], lower back [24.2% (n = 87)], and shoulder injuries [23.6% (n = 85)]. Prevalence of injuries was approximately similar between sexes. Substantial injuries were most prevalent in the hip/groin (13.3% [n = 48]) and knee (18.6% [n = 67]) region. Females reported a higher proportion of substantial hip/groin injuries. Most reported injuries were acute except for hip/groin and lower back injuries (74.4% and 81.8% due to overuse). CONCLUSION: Seasonal prevalence of injuries in elite ice hockey players were comparable between sexes. Acute injuries were most common but hip/groin as well as lower back injuries were predominantly due to overuse. The highest reported prevalence was found for hip and groin-, lower back-, and shoulder injuries.

Abstract Objective: Hip fractures in older adults have the highest impact on the patient's health. These injuries result in many complications, reducing functional capability, quality of life, and life expectancy. This study aimed to provide more epidemiological data on the outcomes of these fractures in nonagenarians from a large city treated at a tertiary hospital. Methods: This study consisted of medical record reviews and interviews. Results: In this study, 76 patients underwent 82 surgeries. The mean age of the patients was 92.5 years. Ninety percent of the subjects were female. The patients spent 10.4 days in hospital. Surgery occurred on average 2.3 days after hospitalization. Regarding fractures, 46 were trochanteric (56%), and 34 affected the femoral neck (41.5%). Forty-one surgeries used the short proximal femoral nail (50%), and 18 were partial hip replacements (22%). During hospitalization, 46 patients (55%) had no complications, excluding episodes of delirium, and seven patients (9%) died. Forty-two subjects completed the one-year postoperative follow-up period, with 56% alive and 44% dead. Conclusions: Treating hip fractures in older patients is challenging. Our goal must focus on helping these subjects receive the quickest and least aggressive treatment possible and start mobilization early. We hope the data presented in this study can lead to a better understanding of the characteristics of our nonagenarian population with hip fractures and seek the best possible treatment for them.
Resumo Objetivo: As fraturas de quadril em idosos são as que mais impactam na saúde do paciente e estão associadas a muitas complicações, levando a redução da capacidade funcional, da qualidade de vida e da expectativa de vida. O nosso trabalho visa trazer mais dados epidemiológicos sobre os desfechos dessas fraturas em nonagenários em uma grande cidade atendidos em um hospital terciário. Métodos: O trabalho foi realizado através de revisão de prontuários e entrevistas. Resultados: Foram realizadas 82 cirurgias em 76 pacientes nesse período. A média de idade foi de 92,5 anos, 90% eram mulheres e ficaram 10,4 dias internados. A cirurgia foi realizada em média 2,3 dias após a internação. Do total, 46 fraturas foram trocantéricas (56%) e 34 do colo do fêmur (41,5%). Foram realizadas 41 cirurgias com a técnica da haste cefalomedular curta (50%) e 18 artroplastias parcial de quadril (22%). Durante a internação, 46 pacientes (55%) não apresentaram complicações, excluindo episódios de delirium, e 7 pacientes (9% dos casos) evoluíram para óbito. 42 pacientes já fecharam 1 ano após cirurgia: 56% estão vivos e 44% evoluíram para óbito. Conclusões: O tratamento de fraturas de quadril em pacientes idosos é desafiador. O nosso objetivo deve estar focado em ajudar esses idosos a receber um tratamento rápido e menos agressivo possível e a mobilizar precocemente. Esperamos que, com os dados apresentados nesse trabalho, possamos entender melhor acerca das características da nossa população nonagenária vítimas de fratura de quadril e buscar o melhor tratamento possível para esses pacientes.

Purpose: Osteoarthritis (OA) is a degenerative joint disease which is categorized via destruction of joint cartilage and it also affects the various joints, especially knees and hips. Sinomenine active phytoconstituents isolated from the stem of Sinomenium acutum and already proof anti-inflammatory effect against the arthritis model of rodent. In this experimental protocol, we scrutinized the anti-osteoarthritis effect of sinomenine against monosodium iodoacetate (MIA) induced OA in rats. Methods: MIA (3 mg/50 µL) was used for inducing the OA in the rats, and rats received the oral administration of sinomenine (2.5, 5 and 7.5 mg/kg body weight) up to the end of the experimental study (four weeks). The body and organs weight were estimated. Aggrecan, C-terminal cross-linked telopeptide of type II collagen (CTX-II), glycosaminoglycans (GCGs), monocyte chemoattractant protein-1 (MCP-1), Interferon gamma (IFN-γ), antioxidant, inflammatory cytokines, inflammatory mediators and matrix metalloproteinases (MMP) were analyzed. Results: Sinomenine significantly (P < 0.001) boosted the body weight and reduced the heart weight, but the weight of spleen and kidney remain unchanged. Sinomenine significantly (P < 0.001) reduced the level of nitric oxide, MCP-1 and improved the level of aggrecan, IFN-γ and GCGs. Sinomenine remarkably upregulated the level of glutathione, superoxide dismutase and suppressed the level of malonaldehyde. It effectually modulated the level of inflammatory cytokines and inflammatory mediators and significantly (P < 0.001) reduced the level of MMPs, like MMP-1, 2, 3, 9 and 13. Conclusions: Sinomenine is a beneficial active agent for the treatment of OA disease.

Background: Gout is known as arthropathy due to the deposit of monosodium urate crystals; This pathology comprises a set of clinical and radiographic tests in the context of the intra-articular presence of said crystals. It is a chronic disease associated with other comorbidities such as arterial hypertension, osteoarthritis, diabetes mellitus, etc. The case of a patient with gouty arthritis with consequent hip lesion with a pseudotumoral appearance difficult to diagnose is presented, in order to highlight the importance of this, as well as the appropriate follow-up and treatment for this chronic pathology. Clinical case: A 51-year-old male patient, with a history of hip osteoarthritis and gout. The symptoms and signs were pain in the right hip with an 8/10 on an analogue pain scale, associated with functional limitation characterized by reduced range of motion and impossibility of standing. Imaging studies are carried out which are suggestive of a tumor lesion at the proximal femur with malignant characteristics, for which a biopsy and subsequent histopathological diagnosis of gouty tophi is performed. Conclusions: Gout is a prevalent disease in the adult population, however, its infrequent joint location can result in a difficult diagnosis, so it is necessary not to rule out this entity and to carry out specific studies for its identification.
Introducción: se conoce como gota a la artropatía por depósito de cristales de urato monosódico. Esta patología comprende un conjunto de hallazgos clínicos y radiográficos en el contexto de presencia intraarticular de dichos cristales. Es una enfermedad crónica asociada a otras comorbilidades como: hipertensión arterial, osteoartrosis, diabetes mellitus, etc. Se presenta el caso de un paciente con artritis gotosa con consecuente lesión en cadera, con aspecto pseudotumoral de difícil diagnóstico, a fin de resaltar su importancia, así como el seguimiento y tratamiento oportunos para esta patología crónica. Caso clínico: paciente hombre de 51 años, con antecedentes de artritis gotosa; quien cursa con cuadro clínico de, aproximadamente, cuatro años de evolución, caracterizado por dolor en cadera derecha de intensidad 8/10 en escala análoga del dolor, sin irradiación, asociado a limitación funcional caracterizada por reducción de arcos de movilidad e imposibilidad para la bipedestación. Se realizan estudios imagenológicos los cuales son sugestivos de lesión tumoral a nivel de fémur proximal de características de malignidad, por lo cual se realiza biopsia y posterior diagnóstico histopatológico de tofos gotosos. Conclusiones: la gota es una enfermedad prevalente en la población adulta, sin embargo, la localización articular infrecuente puede resultar en un difícil diagnóstico, por lo que se requiere no descartar esta entidad y la realización de estudios específicos para su identificación.

OBJECTIVE: To explore the diagnostic value of ultrasound for asymptomatic anterosuperior acetabular labral tears (ALT). METHODS: From August 2018 to February 2020, a total of 64 asymptomatic volunteers (101 hips) were recruited to complete 3.0T magnetic resonance imaging (MRI) and ultrasound examination. Among these asymptomatic volunteers, 31 were male and 33 were female, with the median age 35 (32, 39) years. Using 3.0T MRI findings as golden standard, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ultrasound were calculated. RESULTS: The results showed the presence of unilateral or bilateral ALT in 33 (51.56%) asymptomatic vo-lunteers with a total of 47 hips (46.53%). Of the 37 asymptomatic volunteers with bilateral hip MRI examination, 14 had bilateral ALT and 8 had unilateral ALT. Of the 27 asymptomatic volunteers who underwent unilateral hip MRI, 11 had ALT. Of the 33 asymptomatic volunteers with labral tears, 11 were male and 22 were female, with 30 right hips and 17 left hips. The median age was 36 (33, 40) years in the ALT group and 34 (32, 38) years in the non-ALT group. There was no significant difference in age between the two groups (P > 0.05). In the asymptomatic population, the abnormal anterosuperior acetabular labrum manifestations on ultrasound were intra-labrum cleft in 26 cases, labral heterogeneous echogenicity in 25 cases, paralabral cysts in 2 cases, and labral focal hyperechoic area in 12 cases. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy for ALT diagnosed by ultrasound were 73.53%, 67.16%, 53.19%, 83.33% and 69.31%, respectively. The cross- sectional area (CSA) of the anterosuperior acetabular labrum was 0.20 (0.15, 0.24) cm2 in this study. The labral median CSA of the ALT group and non-ALT group were 0.22 (0.17, 0.28) cm2 and 0.17 (0.14, 0.21) cm2, respectively, with a statistically significant difference (P < 0.001). CONCLUSION: The ALT are common findings in asymptomatic volunteers on MRI. Intra-labrum cleft and labral heterogeneous echogenicity are common ultrasonographic signs in asymptomatic volunteers with ALT. The labra were more swollen in the asymptomatic volunteers with ALT compared to those without ALT.

PURPOSE: To describe the injury prevalence, injury pattern, and potential baseline risk factors for injuries in male and female adolescent and adult amateur football players. METHODS: This prospective study followed adolescent and adult amateur football players over one season March-October 2020. The study was completed by 462 players (130 men, age 20.0 ± 5.7, 14-46 years) who answered a baseline survey and a weekly web survey during the season. A total of 1456 weekly surveys were registered from males and 5041 from females. Injuries were recorded with the Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC-O2). Potential baseline risk factors (age, performance of strength/conditioning training, participation in other sports, perceived importance of sporting success, self-rated training and match load, perceived balance between training/match load and recovery, previous/present injury at start of season, and injury beliefs) and their association with injury were analysed with Poisson regressions within each sex. RESULTS: Males reported 95 injuries (262 injury weeks, weekly prevalence 18.0% (95% CI 16.1-20.1)) and females 350 injuries (1206 injury weeks, weekly prevalence 23.9% (95% CI 22.8-25.1)). Gradual-onset injuries accounted for 57% of the injuries in males and 66% in females. For males, substantial injuries were most common in the hip/groin (weekly prevalence 3.8%), ankle (2.1%), posterior thigh (2.0%), and knee (2.0%); and for females, in the knee (4.3%), ankle (2.5%), and lower leg/Achilles tendon (2.0%). Significant risk factors for injury were higher age (rate ratio males 1.05 per year increase (95% CI 1.02-1.08), females 1.03 (95% CI 1.01-1.05)), and present injury at baseline (males 1.92 (95% CI 1.27-2.89), females 1.58 (95% CI 1.19-2.09)). CONCLUSION: At any given week, almost one in five male and one in four female amateur football players reported new or ongoing injuries. Hip/groin injuries were more frequent in males, while female players had a higher prevalence of knee injuries. Older players and those with an existing injury at the start of the season were more prone to new injury during the season. Rehabilitation of pre-season injury and complaints are key to reduce the injury burden in amateur football. LEVEL OF EVIDENCE: Level II. Trial registration number NCT04272047, Clinical trials.

BACKGROUND: Venous thromboembolism (VTE) is one of the most common complications of hip fracture surgeries, and it is unclear whether delayed surgery affects the incidence of VTE. This study aimed to examine the association between delayed surgery and VTE incidence by statistically adjusting for factors that may influence VTE incidence. METHODS: We included 862 patients ≥ 65 years with hip fractures who underwent surgery between October 2010 and December 2020. We examined the effect of surgical delay 48 h after injury on postoperative VTE. Patients with and without VTE were assigned to groups V and NV, respectively. Those with and without proximal deep venous thrombosis (DVT) were assigned to PD and NPD groups, respectively. Univariate analysis was performed to identify factors that might influence DVT development. Risk factors for developing VTE and proximal DVT were analyzed using logistic regression analysis to determine whether delayed surgery was a risk factor. RESULTS: VTE was observed in 436 patients (40%) and proximal DVT in 48 patients (5.6%). Univariate analysis showed significant differences in the time from trauma to surgery between the V and NV groups and between the PD and NPD groups. In multivariate analysis, surgery 48 h later was also a risk factor for developing VTE and proximal DVT. CONCLUSION: A delay in surgery beyond 48 h after a hip fracture injury is a risk factor for developing VTE and proximal DVT.

PURPOSE: This study aimed to compare and rank gluteal muscle forces in eight hip-focused exercises performed with and without external resistance and describe the underlying fiber lengths, velocities, and muscle activations. METHODS: Motion capture, ground reaction forces, and electromyography (EMG) were used as input to an EMG-informed neuromusculoskeletal model to estimate gluteus maximus, medius, and minimus muscle forces. Participants were 14 female footballers (18-32 yr old) with at least 3 months of lower limb strength training experience. Each participant performed eight hip-focused exercises (single-leg squat, split squat, single-leg Romanian deadlift [RDL], single-leg hip thrust, banded side step, hip hike, side plank, and side-lying leg raise) with and without 12 repetition maximum (RM) resistance. For each muscle, exercises were ranked by peak muscle force, and k-means clustering separated exercises into four tiers. RESULTS: The tier 1 exercises for gluteus maximus were loaded split squat (95% confidence interval [CI] = 495-688 N), loaded single-leg RDL (95% CI = 500-655 N), and loaded single-leg hip thrust (95% CI = 505-640 N). The tier 1 exercises for gluteus medius were body weight side plank (95% CI = 338-483 N), loaded single-leg squat (95% CI = 278-422 N), and loaded single-leg RDL (95% CI = 283-405 N). The tier 1 exercises for gluteus minimus were loaded single-leg RDL (95% CI = 267-389 N) and body weight side plank (95% CI = 272-382 N). Peak gluteal muscle forces increased by 28-150 N when exercises were performed with 12RM external resistance compared with body weight only. Peak muscle force coincided with maximum fiber length for most exercises. CONCLUSIONS: Gluteal muscle forces were exercise specific, and peak muscle forces increased by varying amounts when adding a 12RM external resistance. These findings may inform exercise selection by facilitating the targeting of individual gluteal muscles and optimization of mechanical loads to match performance, injury prevention, or rehabilitation training goals.
