Hip abductor tears have recently gained recognition as a more prevalent injury than previously thought. This article will detail the pathophysiology of injury, physical symptoms commonly found at presentation, diagnostic imaging to best diagnose tears and when they should be ordered, and how to properly classify the injury and finally summarize the treatment options available with expert opinions about which are most successful.

The impact of nonoperative hip and core injuries on National Football League athlete performance.

OBJECTIVES: Hip and core injuries are common in National Football League (NFL) athletes; however, the impact following injury remains unclear. The goal of this manuscript was to determine the impact of nonoperative hip and core injuries on return to play and performance. METHODS: NFL athletes who sustained a hip or core injury treated nonoperatively between 2010 and 2016 were identified. Offensive and defensive power ratings were calculated for each player's injury season and two seasons before and after to assess longitudinal impact. A matched control group without an identified hip and/or core injury was assembled for comparison. RESULTS: A total of 41 offensive and 71 defensive players with nonoperative hip or core injury were analyzed. All athletes returned to play; offensive and defensive players missed 4.0 ± 5.2 and 3.1 ± 2.6 games after injury, respectively. Offensive players played fewer cumulative career games returning from core injury versus hip (23.5 ± 20.6 vs 41.0 ± 26.4). Defensive players played fewer games (58.1 ± 41.1 versus 37.4 ± 27.1, p < 0.05) with lower defensive power rating (133.9 ± 128.5 versus 219.8 ± 212.2, p < 0.05) cumulatively after hip or core injury. Additionally, 2 years following injury, defensive players played fewer games compared to controls (9.5 ± 7.0 versus 10.9 ± 6.8, p < 0.05). Following hip injury specifically, NFL defenders played fewer games (39.8 ± 27.9 vs 61.9 ± 38.8; p < 0.05) and had a lower defensive power rating (145.9 ± 131.7 vs 239.0 ± 205.9; p < 0.05) compared to before injury. CONCLUSION: Overall, NFL players return to play following nonoperative hip and core injuries. Defensive players played in fewer games following hip or core injury compared to controls; offensive players were unaffected. Hip injuries have a greater impact on performance compared to core injuries in defensive athletes; offensive players played fewer games upon return from core injury.

Mejoría de la supervivencia a los 10 años con la prótesis de recubrimiento de cadera tipo Durom en pacientes seleccionados. Experiencia de un hospital público universitario / Improvement of survival after 10 years with the Durom-type hip resurfacing prosthesis in selected patients: Experience of a public university hospital

Introducción: Las prótesis de recubrimiento son una alternativa válida para el tratamiento de los trastornos degenerativos de cadera del adulto joven, pero han sido reportados malos resultados y efectos adversos en partes blandas con niveles altos de cromo y cobalto, limitándose sus indicaciones. Nuestro objetivo es analizar resultados clínicos, funcionales y de supervivencia del modelo Durom a los 10 años de su implantación en un hospital público. La hipótesis es que se obtienen mejores resultados y supervivencia en pacientes seleccionados según criterios de la FDA. Material y métodos: Estudio retrospectivo de cohortes con 83 pacientes, 91 caderas en 76 hombres y 7 mujeres operados entre 2005 y 2013 con prótesis tipo Durom. Estudio demográfico, diagnóstico, IMC, radiológico con posición de implantes, estrechamiento del cuello y tipo de unión ósea, niveles de cromo y cobalto en suero, valoración funcional según MPD y HSS, complicaciones y supervivencia a los 10 años de seguimiento. Se selecciona una cohorte de varones activos menores de 65 años y cabezas superiores a 48mm para la misma valoración. Resultados: El tiempo de seguimiento fue de 121 meses, con un rango de 84 a 176 meses. Con una edad media de 52,78 años, con 4 defunciones y pérdida de seguimiento de 3 casos. Se producen 12 complicaciones que precisan reintervención (14,45%) con 2 infecciones crónicas, 4 fracturas del cuello femoral, 4 aflojamientos acetabulares y 2 casos de pseudotumores. La supervivencia global fue del 85,4% (71-91,9), y del 87,85% (85,5-91,1) en ausencia de infección a los 10 años. No hubo relación estadística entre las complicaciones y el estrechamiento de cuello y los ángulos de inclinación de los componentes. En pacientes seleccionados, en 69 hombres y 73 caderas obtenemos una supervivencia global del 91,82% y, excluyendo la infección, del 93,18% a los 10 años.(AU)

Introduction: Hip resurfacing arthroplastys are a valid alternative for the treatment of degenerative hip disorders in young adults. Poor results and adverse soft tissue effects have been reported with high levels of chromium and cobalt, limiting its indications. Objective is to analyze clinical and functional survival results of the Durom system 10 years after its implementation in a public hospital. The hypothesis is that better results and survival are obtained in patients selected according to FDA criteria. Material and methods: Retrospective cohort study of 83 patients, 91 hips in 76 men and 7 women operated between 2005 and 2013 with Durom-type prostheses. Demographic study, diagnosis, BMI, radiological study, serum chromium cobalt levels, functional assessment according to MPD and HSS, complications and survival at 10 years of follow-up. A cohort of active men under 65 years of age and heads over 48mm is selected. Results: Follow-up time of 121 months with a range from 84 to 176 months. With a mean age of 52.78 years, with 4 deaths and loss of follow-up of 3 cases. There are 12 complications that require reoperation (14.45%) with 2 chronic infections, 4 femoral neck fractures, 4 acetabular loosening and 2 cases of pseudotumors. With an overall survival of 85.4% (71-91.9) and 87.85% (85.5-91.1) in the absence of infection. No statistical relationship between complications and neck narrowing and the angles of inclination of the components. In selected patients, 69 men and 73 hips, we obtained an overall survival of 91.82% and excluding infection of 93.18% at 10 years. Conclusions: The indication of the Durom system in the treatment of degenerative processes in selected active young patients presents better results and survival at 10 years, although somewhat lower than other highly indicated veneering models.(AU)

Hockey: a pain in the butt! Isolated superior gluteal artery rupture following blunt pelvic trauma - an unusual case.

Superior gluteal artery rupture is a rare complication of trauma but a significant one with potential for substantial morbidity and mortality. This case demonstrates the importance of early diagnosis and treatment of this injury pattern. Endovascular embolisation has become the most effective treatment for pelvic haemorrhage. Acknowledgement of this rare injury as a differential diagnosis is vital to facilitate rapid diagnosis and appropriate treatment.

Hip and Knee Injuries.

Hip and knee injuries are a common presenting concern for patients to a primary care office. This pathology represents a large differential and it can often be a diagnostic challenge for providers to determine the etiology of a patient's symptoms. This article discusses several of the most common causes for hip and knee pain while providing an evidence based review of physical examination maneuvers, imaging studies and treatment modalities to assist a primary care provider when encountering active patients with underlying hip or knee pain.

Use of Platelet-Rich Plasma for the Treatment of Acetabular Labral Tear of the Hip: A Pilot Study.

OBJECTIVE: This study aims to assess whether ultrasound-guided injection of platelet-rich plasma can safely and effectively treat symptoms associated with acetabular hip labral tears. DESIGN: Institutional review board approval was gained for a prospective study of eight patients (N = 8), who have previously failed conservative management, to receive ultrasound-guided injection of platelet-rich plasma at the site of hip labrum tear. We assessed pain reduction and functional ability at baseline and then 2, 6, and 8 wks after injection, using the visual analog scale and Harris Hip Score, respectively. RESULTS: Statistically significant differences in Harris Hip Score were seen 2 wks (86.5 ± 10.8, P < 0.01), 6 wks (88.0 ± 10.7) P < 0.01), and 8 wks (92.1 ± 11.6, P < 0.01) after injection as compared with baseline (76.0 ± 13.4). Corresponding improvements were seen in visual analog scale 2 wks (1.0, P < 0.01 at rest, 2.5, P < 0.01 with activity), 6 (0.9, P < 0.01 at rest, 2.3, P < 0.01 with activity), and 8 wks (0.5, P < 0.01 at rest, 1.3, P < 0.01 with activity) compared with baseline (3.8 at rest, 5.4 with activity). CONCLUSIONS: Ultrasound-guided injection of platelet-rich plasma holds promise as an emerging, minimally invasive technique toward symptom relief, reducing pain, and improving function in patients with hip labral tears.

The Economic Burden of Non-fatal Musculoskeletal Injuries in Northeastern Tanzania.

BACKGROUND: Although musculoskeletal injuries have increased in sub-Saharan Africa, data on the economic burden of non-fatal musculoskeletal injuries in this region are scarce. OBJECTIVE: Socioeconomic costs of orthopedic injuries were estimated by examining both the direct hospital cost of orthopedic care as well as indirect costs of orthopedic trauma using disability days and loss of work as proxies. METHODS: This study surveyed 200 patients seen in the outpatient orthopedic ward of the Kilimanjaro Christian Medical Center, a tertiary hospital in Northeastern Tanzania, during the month of July 2016. FINDINGS: Of the patients surveyed, 88.8% earn a monthly income of less than $250 and the majority of patients (73.7%) reported that the healthcare costs of their musculoskeletal injuries were a catastrophic burden to them and their family with 75.0% of patients reporting their medical costs exceeded their monthly income. The majority (75.3%) of patients lost more than 30 days of activities of daily living due to their injury, with a median (IQR) functional day loss of 90 (30). Post-injury disability led to 40.6% of patients losing their job and 86.7% of disabled patients reported a wage decrease post-injury. There were significant associations between disability and post-injury unemployment (p < .0001) as well as lower post-injury wages (p = .022). CONCLUSION: This exploratory study demonstrates that in this region of the world, access to definitive treatment post-musculoskeletal injury is limited and patients often suffer prolonged disabilities resulting in decreased employment and income.

Morel-Lavallée lesion. / Morel-Lavallées lesjon.

Background: Knowledge about diagnostics and treatment of chronic Morel-Lavallée lesions is sparse. Material and method: The patient presented is a 65-year-old woman who develops a post-traumatic chronic Morel-Lavallée lesion. The paper describes the course of her treatment including dos and don'ts with reference to literature from a systematic PubMed search. Results and interpretation: The Morel-Lavallée lesion is often missed in the trauma setting during both primary, secondary and tertiary examination, resulting in a chronic lesion. Knowledge of the lesion minimises this risk. The gold standard for diagnosis is magnetic resonance imaging, but ultrasonography may also be used in the acute setting. The chronic lesion can be successfully treated with doxycycline-induced obliteration of the cavity followed by compression treatment for a short period.

Nonoperative Management of Labral Tears of the Hip in Adolescent Athletes: Description of Sports Participation, Interventions, Comorbidity, and Outcomes.

CONTEXT: Hip injury among young athletes is increasing, especially hip labral tears. Some tears may require surgical intervention, especially if they are associated with boney pathology such as femoroacetabular impingement (FAI). A protocol for nonoperative treatment of the hip labral tears is not well established. OBJECTIVE: To identify current nonoperative treatment options, comorbidities, sports participation, and outcomes of adolescent athletes who were diagnosed with hip labral tears. STUDY DESIGN: Retrospective chart review. SETTING: A regional tertiary level medical and academic institution. PARTICIPANTS: Physically active 8- to 20-year-old males and females who were diagnosed with hip labral tears in 2010 to 2013. MAIN OUTCOME MEASURES: Nonoperative treatment interventions including physical therapy (PT), intraarticular injection (IAI), the type of sports participation, and comorbidity were extracted. STATISTICAL ANALYSIS: Descriptive statistics and χ tests were used with a priori alpha level <0.05. RESULTS: Among 76 adolescent athletes who were diagnosed with hip labral tear, 52 (68.4%) had PT, 55 (72.4%) received IAI, and 43 (56.6%) experienced both PT and IAI interventions. Top 3 sports participated were dance (18.4%), soccer (14.5%), and gymnastics (7.9%). The most common comorbidity was FAI, which was observed in 46 individuals (60.5%). Although there was no difference in a proportion of FAI cases between sexes, a greater proportion of surgical cases were observed among hip labrum-injured athletes with FAI compared with those without FAI (P = 0.032). CONCLUSIONS: Adolescent athletes with hip labral tears often receive PT, IAI, and a combination of both, as nonoperative treatment options in this study cohort. The adolescent athletes who sustained hip labral tears with comorbidity of FAI had significantly greater proportion of surgical cases after nonoperative treatments.

Gluteus medius tears of the hip: a comprehensive approach.

Greater trochanteric pain syndrome (GTPS) is a common clinical condition that can affect a wide range of patients. Historically, the condition has been associated with trochanteric bursitis. More recently, however, a growing body of literature has demonstrated gluteus medius tendinopathy and tearing is present in many cases of GTPS. Pathology of the gluteus medius can result in significant hip pain, loss of motion, and decreased function. Affected patients characteristically have symptoms including lateral hip pain and a Trendelenburg gait, which may be refractory to conservative management such as non-steroidal anti-inflammatory drugs (NSAIDs), physical therapy, and injections. In these cases, both open and arthroscopic repair techniques have been described, with recent literature demonstrating excellent patient-reported outcomes. We present a comprehensive review of gluteus medius tears including relevant anatomy, clinical evaluation, diagnosis, and treatment options.

Hip and Core Muscle Injuries in Soccer.

Soccer is the most popular sport in the world and has the fourth highest number of sports injuries. Hip and groin injuries account for 14% of soccer injuries and can be difficult to recognize and treat as they often require a high level of suspicion and advanced imaging. Groin pain can be separated into 3 categories: (1) defined clinical entities for groin pain (adductor-related, iliopsoas-related, inguinal-related [sports hernias/athletic pubalgia], and pubic-related groin pain), (2) hip-related groin pain (hip morphologic abnormalities, labral tears, and chondral injuries), and (3) other causes of groin pain. Conservative approaches are typically the first line of treatment, but operative intervention has been reported to result in higher rates of return to sport in athletes with hip-related and inguinal-related groin pain injuries. In patients with concurrent hip-related and inguinal-related groin pain, the failure to recognize the relationship and treat both conditions may result in lower rates of return to sport. Preseason screening programs can identify high-risk athletes, who may benefit from a targeted prevention program. Further study on exercise therapy, early surgical intervention, and potential biologic intervention are needed to determine the most effective methods of preventing groin injuries in athletes.

Articular and peri-articular hip lesions in soccer players. The importance of imaging in deciding which lesions will need surgery and which can be treated conservatively?

Soccer is one of the most popular sports worldwide engaging millions of participants each year. During play, injuries occur rather frequently and most of them involve the hip joint and the surrounding structure. In professional athletes, injuries are often complex scenarios and in the case of misdiagnosis, patients' return to play is delayed or it may progress to a more serious injury with consequent damage for their career and for the soccer team. The most frequent articular pathologies are Femoro-acetabular impingement and labral tears. Stress fracture, avulsion, ischiofemoral impingement, subspine impingement, athletic pubalgia, muscle injuries and Morel-Levallèe lesion are the most frequent hip peri-articular pathologies whereas snapping hip may be both intra- or extra-articular pathology. With an increasing number of football players, the radiologist plays a crucial role in the detection and characterization of the extent of the injuries. This article reviews the current imaging concepts frequently seen in injuries around the hips of professional football players focusing in particular on the most suitable therapeutic approaches, whether surgical or conservative.

Golf Injuries: Epidemiology, Pathophysiology, and Treatment.

Increasing numbers of people are playing golf. Golf is a unique sport in that the ability to participate at a high level is not limited by age. In addition, participants tend to play more rather than less as they grow older. Injuries can occur at any point during the golf swing, from takeaway through follow-through. Upper extremity injuries can affect the hands, elbow, and shoulder and are usually a result of the golf swing at impact. Injuries are also common in the lower back as well as the lower extremities. Most injuries are the result of overuse and poor swing mechanics. When treating golfers, it is important to have a good understanding of the biomechanics and forces of the golf swing to diagnose and manage the vast spectrum of injuries incurred in this sport.

Hip Dislocations in the Emergency Department: A Review of Reduction Techniques.

BACKGROUND: Hip dislocations are a common presentation in the Emergency Department (ED) and require urgent reduction to reduce the risk of avascular necrosis. Over 90% of all dislocations can successfully be reduced in the ED and there is evidence that cases awaiting operative reduction result in significant delays. DISCUSSION: While there is limited data comparing specific techniques, the individual success rates of most maneuvers range from 60-90%. Additionally, each technique has distinct advantages and limitations associated with its use. CONCLUSIONS: It is important for Emergency Physicians to be familiar with several different reduction techniques in case the initial reduction attempt is unsuccessful or patient characteristics limit the use of certain maneuvers. This article reviews a number of reduction techniques for hip dislocations, variations on these techniques, and advantages and disadvantages for each approach.

Traumatic hip dislocation in pediatric patients.

Traumatic hip dislocations constitute approximately 5% of all pediatric dislocations and typically result from high-energy trauma. However, pediatric hip dislocations can also occur as a result of minor energy due to flexibility of the joint structures of the immature hip. Children with a posteriorly dislocated hip present with the injured hip in flexion, adduction and internal rotation. Spontaneous relocation of hip dislocation is frequent and a thorough physical examination of the whole lower extremity is always required to reduce the chance of missing hip dislocation/subluxation. Dislocated hips should be emergently repositioned under general anesthesia. MRI is indicated after reduction and in patients after spontaneous relocation if labral interposition is suspected in plain radiographs.
