Prevention of hip and knee injuries in ballet dancers.

Hip problems form about 10% (7.0 to 14.2%) of most published series of ballet injuries. The abnormally large range of external rotation needed for a perfect turnout is primarily due to soft tissue adaptation, more readily achieved in the young dancer. Insufficient range of motion at the hip throws considerable stress on the other lower limb segments. The snapping hip syndrome is common (43.8% of hip problems), with about one-third associated with pain. A tight iliotibial band may contribute to this, and balanced flexibility requires special attention to abductor stretching. The external clicking hip must be distinguished from the internal clicking hip, which is associated with the joint and psoas tendon. Stress fractures of the hip are easily overlooked and, if undetected, they may progress to a complete fracture. Knee problems account for 14.0 to 20% of complaints, and over 50% of these are peri- or retropatellar problems. This includes synovial plica, medial chondromalacia, lateral patella facet syndrome, subluxing patella and the fat pad syndrome. Specific diagnosis leads to specific treatment and the best chance of cure. Mild hyperextension of the knee may be aesthetically desirable, but excessive range leads to symptoms in the posterior capsule and poor control. Young dancers with a tendency to very lax joint structures should be identified early and protected from overstretching. In the author's series, meniscal lesions did not appear to be as big a problem as reported elsewhere in the literature. Ballerinas appear to have less leg strength than other groups of athletes, having only 77% of the weight-predicted norms. The introduction of strength training for male and female dancers may reduce injuries and improve balance, but it requires an intensive educational programme to dispense with the many myths. There are several references to the development of early arthritis but, while relatively common in the foot, symptomatic arthrosis in ballet dancers' hips and knees is not more prevalent than in the general population. The young age at which serious dance training begins, the long and rigorous hours of practice, the thin ballet slipper, dancing en pointe and unusual dietary regimens may all contribute to injury patterns in varying degrees.

Occult acetabular fracture in an elderly runner.

STUDY DESIGN: Resident's case problem. BACKGROUND: A 79-year-old African American male runner sustained a left hip injury while jogging on a running track. Initial radiographs did not show any bony injuries and the patient was diagnosed with hip tendonitis. The patient was initially treated conservatively with medications and referred to a local physical therapy clinic for thermal modalities and therapeutic exercises. The patient failed to show any improvement despite a period of conservative treatment. The author examined the patient 6 months postinjury at a university physical therapy department. DIAGNOSIS: The author suspected the presence of a possible fracture and the patient was referred to an orthopaedic surgeon. Subsequent radiographic imaging studies including a CT scan revealed a supra-acetabular fracture. The patient underwent a total hip arthroplasty approximately 1 year after the initial injury and has since recovered well. DISCUSSION: It is not uncommon for runners or joggers to develop hip or pelvic pain, but there has been no prior report in the literature of the occurrence of an acetabular hip fracture while jogging. This resident's case problem illustrates the challenges of arriving at an accurate diagnosis in the presence of a rare fracture and the need for careful follow-up, especially among elderly individuals with cognitive deficits.

Nerve injury in traumatic dislocation of the hip.

Neurologic injury often accompanies traumatic dislocation and fracture-dislocation of the hip. A review of the literature reveals an incidence of approximately 10% in adults and 5% in children. The sciatic nerve, usually the peroneal branch, is most often injured, and this complication can be seen after all types of posterior fracture-dislocations and simple posterior dislocations. The sciatic nerve can be acutely lacerated, stretched, or compressed, or later encased in heterotopic ossification. Neurologic examination at the time of injury often is difficult but is extremely important. Once a nerve injury is discovered, prompt closed reduction must be attempted to relieve distortion of the nerve from a dislocated femoral head or displaced acetabular fracture. Considerable controversy surrounds the recommendations for additional treatment of nerve injury once the hip has been reduced. At least partial recovery of nerve function occurs in 60% to 70% of patients, with no clear correlation with injury or treatment type. Rehabilitation of patients with sciatic nerve injury must begin as early as possible and should focus on the prevention of an equinus foot deformity. Magnetic resonance neurography may become useful in the future for initial evaluation of patients with this injury.

Hip arthroscopy to remove loose bodies after traumatic dislocation.

OBJECTIVES: This study was designed to review the incidence of arthroscopically detected intra-articular loose bodies found in patients after traumatic hip dislocation or small acetabular wall fracture which would not otherwise be treated without surgery. DESIGN: Retrospective review. SETTING: Level 1 academic trauma center. PATIENTS: Thirty-six patients who sustained traumatic hip injuries and subsequently had 39 hip arthroscopies between November 1997 and January 2004 were reviewed. INTERVENTION: All patients had standard AP pelvis x-rays and CT scans performed. At our institution, patients with hip dislocations or acetabular wall fractures not otherwise requiring surgery are routinely offered hip arthroscopy to remove loose bodies. The radiographs were reviewed to determine incidence of loose bodies or nonconcentric reduction before hip arthroscopy. Chart review provided incidence of loose bodies found during arthroscopy. MAIN OUTCOME MEASUREMENTS: Comparison was made between radiographic data obtained preoperatively and operative findings. RESULTS: Loose bodies were found in the hips of 33 of 36 patients (92%) who were arthroscoped. Loose bodies were found in 7 of 9 cases (78%) in which standard radiographic studies (AP pelvis x-rays and CT scan) found no loose bodies and a concentric reduction. CONCLUSIONS: Loose bodies are routinely present after closed treatment of hip dislocations or wall fractures not otherwise requiring surgery, even when radiographs are negative. Hip arthroscopy may be indicated for loose body removal when open treatment is not otherwise necessary.

Functional outcome at 2.5, 5, 9, and 24 months after injury in the Netherlands.

BACKGROUND: The collection of empirical data on the frequency, severity, and duration of functioning is a prerequisite to identify patient groups with long term or permanent disability. METHODS: We fielded postal questionnaires in a stratified sample of 8,564 injury patients aged 15 years and older, who had visited an emergency department in the Netherlands. Measurements were at 2.5, 5, 9, and 24 months after the injury and included a generic health status classification (EQ-5D), socio-demographic, and medical information. We analyzed determinants of long-term functional outcome by multivariate regression analysis. RESULTS: Five months after the injury health status of nonhospitalized injury patients was comparable to the general population's health (EQ-5D summary measure 0.87). Health status of patients admitted for 3 days or less improved until 9 months (0.82). For those admitted more than 3 days health status improved until 24 months (0.48 toward 0.67), but remained below population norms. Hospitalization, age and sex (females), type of injury (spinal cord injury, hip fracture, and lower extremity injury), and comorbidity were significant predictors of poor functioning in the long term. CONCLUSIONS: Recovery patterns vary widely between nonhospitalized, shortly, and long hospitalized injury patients. Nonhospitalized injury patients recover within 5 months from an injury whereas a considerable group of hospitalized injury patients suffer from persistent health problems. Our study indicates the importance of health monitoring with an adapted longitudinal design for injury patients. The time intervals used should match the various stages of the recovery process, which depends on the severity of the injury studied.

Management of civilian gunshot injuries to the hip.

The orthopedic surgeon at a civilian trauma center is likely to encounter a gunshot injury to the hip. The nonmilitary literature regarding this injury gives few guidelines regarding an appropriate diagnostic evaluation or the indication for arthrotomy. We found that the best diagnostic test to detect joint penetration was hip aspiration followed by an arthrogram. Selected cases can be treated successfully with antibiotic therapy without an arthrotomy. These cases involve a low-velocity missile that passes through the joint, causes minimal bone disruption, and is free of bowel contaminants. If an arthrotomy is not performed, the physician must follow the patient with repeated physical examinations, complete blood counts, and a hip aspiration whenever infection is suspected. All transbdominal hip injuries require an immediate arthrotomy. In this series, bullets left in contact with joint fluid resulted in joint destruction or infection. Each patient with a displaced femoral neck fracture had a poor outcome with internal fixation. Hip arthroplasty or fusion should be considered as elective procedures for definitive management of these injuries.

Imaging of hip and groin injuries in athletes.

Proper function of the hip joint is imperative for athletes who participate in sporting activities that rely on utilization of the lower extremity; these primarily include kicking, running, and jumping activities. Sports-related injuries of the hip and groin are not frequent sources of disability in athletes; however, they may present a significant diagnostic dilemma, both from a clinical and radiological standpoint. Delay in diagnosis and treatment may result in undesired complications, such as premature degenerative disease, as well as time lost from athletic activities. Magnetic resonance (MR) imaging of the hip, particularly following the intra-articular administration of gadolinium, has proven to be extremely valuable in the diagnosis of radiographically occult osseous abnormalities as well as soft-tissue injuries, such as pubalgia, musculotendinous abnormalities, and bursitis. This article will review several pathological conditions of the hip and groin in both recreational and professional athletes, with an emphasis on MR imaging as the modality of choice in the diagnosis of these injuries.

Pediatric athlete hip disorders.

Injuries of the hip and pelvis in pediatric athletes are receiving increased attention. The majority of injuries are soft tissue injuries or apophyseal injuries that heal with nonoperative supportive treatment. Unique injury patterns can be seen in patients who have underlying pediatric hip disorders such as slipped capital femoral epiphysis, and Legg-Perthes disease. With the advent of hip arthroscopy and the development of more advanced imaging of the hip through MR arthrography, internal derangements of the hip such as labral tears, loose bodies, and chondral injuries are being diagnosed and treated with increased frequency. This article reviews the more common injuries of the hip and pelvis in pediatric athletes.

Injuries about the hip and pelvis in the young athlete.

Athletic injuries to the hip and pelvis in pediatric and adolescent athletes, although uncommon, may encompass a wide spectrum of entities. A familiarity with this spectrum and a high index of suspicion in the proper clinical setting will ensure timely diagnosis and help to facilitate implementation of a proper treatment plan thereby assuring safe return to play.

Diagnosis and management of traumatic and atraumatic hip instability in the athletic patient.

Although relatively uncommon compared with the shoulder, hip instability can be a source of significant disability and is a commonly unrecognized injury. Hip instability can be traumatic or atraumatic in origin. Our understanding and treatment plan for hip instability due to traumatic events is well established. However, our understanding and treatment modalities for hip instability due to atraumatic events or repetitive motion in high level athletes are not as well defined. In this article, we will review the spectrum of traumatic and atraumatic hip instability and discuss the relevant anatomy, history, and physical examination findings, imaging studies, and treatment options with a focus on hip arthroscopy, and review of the literature.

Importance of positioning and technical factors in anatomic localization of sporting injuries in scintigraphic imaging.

Sports medicine is becoming increasingly important as more people take up exercise for health and well-being. It is adding to the spectrum of acute and chronic injuries that have traditionally been seen in elite or professional athletes. Because of its high sensitivity and lesion contrast, bone scintigraphy has traditionally played a key role in the detection of such injuries. This role has been reduced in recent times by the increased use of magnetic resonance imaging (MRI), which has functional capability, high-contrast resolution, and high-spatial resolution. Bone scintigraphy has the capability of detecting early cortical ligament avulsion and enthesopathic disease before the onset of edema or changes in bone marrow that are detected by MRI. If this capability is added to more precise anatomic localization of lesions, we may see a resurgence in its use in sports medicine. A number of techniques are presented in this article, encompassing positioning, special views, and tomographic reconstructions, that can significantly improve the accuracy of localization of scintigraphic abnormalities with reference to anatomic models or sources of cross-sectional anatomy.

An analysis of hip dislocations among snowboarders and skiers: a 10-year prospective study from 1992 to 2002.

BACKGROUND: We evaluated the types and mechanisms of hip dislocation sustained while snowboarding and skiing, a subject about which there have been few studies. METHODS: In a prospective cohort study between 1992 and 2002, we studied 30 snowboarders and 8 skiers with hip dislocations. RESULTS: The incidence of dislocation with or without fracture of the hip joint in snowboarders was five times higher than in skiers (0.45 per 100,000 visits for snowboarders vs. 0.09 for skiers). The most remarkable differences between skiing and snowboarding hip injuries were that in the former there was a significantly higher incidence of anterior hip dislocation (p < 0.05) and in the latter there was a significantly higher incidence of posterior hip dislocation (p < 0.05). Furthermore, the rate of type V hip dislocation (with fracture of the femoral head) was higher in snowboarders (9 of 30 cases [30.0%]) than in skiers (1 of 8 cases [12.5%]). CONCLUSION: Hip dislocations are much more common in snowboarders than in skiers. Furthermore, the causes and types of hip dislocation differ between snowboarding and skiing.

Injury in the Australian sport of calisthenics: a prospective study.

The aims of this study were to determine the rate, anatomical regions, onset, severity, and type of injury in the sport of calisthenics and compare injuries reported by elite and non-elite participants. Prospective reports of injuries were collected over a 12-month period from 550 elite and non-elite calisthenics participants. The participants recorded the number of training sessions, competition, and performances per week, hours of training, and information on any injuries sustained each week during the survey period. Five hundred and fifty participants reported 190 injuries during the survey period, 0.4 injuries per participant year or 0.3 injured participants per participant year. The odds ratio of injury in the elite to the non-elite group was 2.0 (95% CI 1.3 to 2.9). Injuries to the lower back (32.4% of all injuries), hip thigh and groin (25.4% of all injuries) were most common. Activities involving lumbar extension (29.8% of all injuries and 61.0% of lower back injuries) were perceived by participants to have led to injury. In general, injuries were minor and mainly involved soft tissue structures (95.6% of all injuries). Participants had difficulty in identifying why their injuries had occurred. Calisthenics participants did not report high injury rates, but activities that involve lumbar extension are implicated in low back injuries and warrant further attention

[Sequelae of home accidents in the aged].

On a department for acute surgery 175 patients, older than 64 years of age, who had an accident at home, were reviewed to determine which injuries occurred. Of the patients 76% were female. More than half of the injuries were fractures, of which wrist and hip injuries occurred most frequently. Soft tissue injuries (wounds and bruises) occurred predominantly in males.

Distribution and severity of injuries associated with hip dislocations secondary to motor vehicle accidents.

The injuries associated with traumatic hip dislocations and their quantitated morbidities were evaluated in this retrospective study of 38 patients. Ninety-five per cent of the patients had associated injuries severe enough for hospitalization on their own merit. Head, chest, and abdominal injuries were seen most frequently. Central dislocations were associated with the most morbidity, but were not different in distribution of injuries. Using eight different measurements of morbidity, including the Injury Severity Score, hip dislocations, in general, had more morbidity than the national injury rates.

Outcome from serious injury in older adults.

PURPOSE: To analyze the research published in peer-reviewed journals between 1996 and 2005 about factors affecting the physical outcomes of older adults after serious traumatic injury. ORGANIZING CONSTRUCT: Twenty-seven primary research studies published in the last 10 years pertained to in-hospital and long-term outcomes of serious injury among older adults. Research specific to isolated hip injury, traumatic brain injury, and burn trauma was excluded. METHODS: An integrative review of research published between January 1996 and January 2005 was carried out to examine the relationship between older age and outcome from severe injury. MEDLINE, BIOSIS previews, CINAHL, and PsycINFO databases were searched using the MeSH terms: injury, serious injury, trauma and multiple trauma, and crossed with type, severity, medical/surgical management, complication, outcome, mortality, morbidity, survival, disability, quality of life, functional status, functional recovery, function, and placement. FINDINGS: Older adults in these studies had higher short- and long-term mortality than did younger adults. The relationship between older age and poorer outcome persisted when adjusting for injury severity, number of injuries, comorbidities, and complications. At the same time, injury severity, number of injuries, complications, and gender each independently correlated with increased mortality among older adults. The body of research is limited by overreliance on retrospective data and heterogeneity in definitional criteria for the older adult population. CONCLUSIONS: Additional research is needed to clarify the contributory effect of variables such as psychosocial sequelae and physiologic resilience on injury outcome. The field of geriatric trauma would benefit from further population-based prospective investigation of the determinants of injury outcome in older adults in order to guide interventions and acute care treatment.
