A ballet dancer with chronic hip pain due to a lesser trochanter bony avulsion: the challenge of a differential diagnosis

Effectiveness of physiotherapy interventions for injury in ballet dancers: A systematic review

Background

The unique repetitive nature of ballet dancing, which often involves transgressing endurance limits of anatomical structures, makes dancers prone to injury. The following systematic review aims to assess the effectiveness of physiotherapy interventions in the treatment of injuries in ballet dancers.

Methods

The review was performed in line with the PRISMA statement on preferred reporting items for systematic reviews and meta-analyses. Six electronic databases (PubMed, Ovid Embase, Cochrane, Medline, PEDro, Google Scholar) were queried. The study populations comprised active ballet dancers and/or ballet school attendees with acute and chronic injuries and those with persistent pain. There were no restrictions regarding age, sex, ethnicity or nationality. The Modified McMaster Critical Review Form for quantitative studies was used to assess the methodological quality of the studies reviewed in accordance with the relevant guidelines.

Results

Out of the total of 687 articles subjected to the review, 10 met the inclusion criteria. Diverse physiotherapeutic interventions were described and effectiveness was assessed using different parameters and measurements. Overall, the results indicate that physiotherapy interventions in ballet dancers exert a positive effect on a number of indices, including pain, ROM and functional status.

Conclusions

Due to the small amount of evidence confirming the effectiveness of physiotherapeutic interventions in ballet dancers after injuries and methodological uncertainties, it is recommended to improve the quality of prospective studies.

Arthroscopic Reduction and Fixation of a Lesser Trochanter Avulsion Nonunion

Identifying and treating avulsion fractures of the pelvis and proximal femur in adolescent athletes has become increasingly more important as the rate of competitive sports participation has grown. The majority of these fractures can be treated conservatively, with most returning to full activity. Surgical treatment of these injuries has been traditionally indicated for >2 cm displacement, painful nonunion, symptomatic exostosis formation, or persistent pain and symptoms. Lesser trochanter avulsion injuries are extremely rare and literature outlining their surgical treatment lacking. We present our method of arthroscopic reduction and fixation of lesser trochanter avulsion nonunions.

The Influence of Position of the Displaced Lesser Trochanter on Clinical Outcome of Unstable Trochanteric Femur Fractures in the Elderly

Purpose

This study aimed to evaluate whether position of the displaced lesser trochanter affected clinical outcome in the treatment of unstable trochanteric fractures with intramedullary fixation.

Patients and Methods

Patients with unstable trochanteric fractures and displaced lesser trochanter who received intramedullary fixation were retrospectively reviewed in this study. Based on displacement distance of the lesser trochanter and whether the lesser trochanter was reduced operatively, patients were divided into three groups: patients with the displaced lesser trochanter less than 1cm (Group A), those with the displaced lesser trochanter more than 1 cm without operative reduction (Group B), or those with operative reduction (Group C). The surgical time, reduction quality, Harris Hip Score (HHS), Visual Analog Score (VAS), and complication rate were reviewed.

Results

There were 42 patients in Group A, 33 in Group B, and 36 in Group C with comparable demographic characteristics. The surgical time was significantly longer in Group C (P=0.009), compared with Groups A and B. Fracture reduction quality was comparable with over 85% good reduction among the three groups. The VAS score was significantly higher in Group B (P=0.023) without significant difference between Groups A and B. The HHS score was slightly lower in Group B, but it did not reach significant difference. The complication rate was statistically higher in Group B (p=0.043) than Groups A and C.

Conclusion

The severe displaced lesser trochanter may increase postoperative complications and postoperative pain in the treatment of unstable trochanteric femur fractures. However, the displaced lesser trochanter may not affect hip function.

Medical attention seeking dance injuries: systematic review of case reports

The objective of this study was to conduct a systematic review of case reports documenting the epidemiology of unique and rare musculoskeletal injuries in dancers. A systematic review was conducted online using PubMed and Google Scholar, as per PRISMA guidelines up to July 30, 2016. Predefined eligibility criteria were applied, and the data thus compiled was analysed. Study quality was assessed based on CARE guidelines. 72 studies reporting 92 dance injuries were included in the review. The average age of dancers was 23 years (SD = 10 years) with majority being females (65%). Chronic injuries were the most common presentation with lower extremity injuries being the commonest. Foot and knee injuries were the top two articulations involved across injuries and groups. Overall bony injuries were most frequently reported, with stress injury being the most common type. Conservative approach was the most commonly reported treatment approach across case reports. The methodological quality of case reports included in the study varied considerably and lacked uniformity. The evidence provided, though not sufficient for any recommendation, it should alert the physicians and those concerned with the primary care of the dancers to be vigilant of the eccentricity and severity of the injuries, their atypical presentation, mode, mechanism and trend, thereby being prepared for the unexpected.

Lesser Trochanter Avulsion Fracture in an Adolescent after Seizure

BACKGROUND

Injury secondary to epileptic seizure is widely documented in the literature. In particular, uncontrolled muscular contractions generated during a seizure can lead to a variety of musculoskeletal injuries.

CASE REPORT

We present the case of a 16-year-old male who presented on two separate occasions after a tonic-clonic seizure with hip pain, an antalgic gait, and marked discomfort on hip flexion. Radiologic investigation revealed an acute isolated fracture of the lesser trochanters. Such fractures in adolescents are normally secondary to athletic injury and in adults are mainly associated with the presence of metastatic bone disease. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We present this case with its previously undocumented mechanism to highlight the injury to frontline emergency medical teams, create awareness of its presentation, and to discuss its potential mechanism and treatment.

Nonpathological Lesser Trochanter Fracture in Adult: Case Report and Brief Review of Literature

Lesser trochanter fractures are rare in adult bones. Few cases have been reported in the literature. When fracture of lesser trochanter is met in patients with closed growth plates, it is likely to be precursor of a silent neoplastic process. A case of lesser trochanter fracture in middle aged female with traumatic aetiology is presented here, which came out to be non-pathological despite high degree of suspicion for contrary. Patient responded positively to conservative line of treatment. Correct evaluation and anticipation of further complication take precedence in case rather than rarity.

A tuber calcanei avulsion fracture developed on the basis of idiopathic osteoporosis in a young male: a case report

Calcaneus fractures constitute 1.2 % of all fractures. Tuber calcanei avulsion fractures constitute 1.3-2.7 % of calcaneus fractures. Osteoporosis, osteomalacia, and diabetes mellitus have been reported to increase the risk of development of these fractures. It has been reported that tuber calcanei avulsion fractures in elderly females might develop due to osteoporosis. As far as we know, no tuber calcanei avulsion fracture developing on the basis of osteoporosis without presence of a trauma has been reported in young males in the literature. In the current case report, a 41-year-old male patient who was admitted with complaints of pain in the left heel and diagnosed with calcaneal avulsion fracture that developed on the basis of idiopathic osteoporosis and who was treated with conservative methods was presented.

Avulsion fracture of the lesser trochanter in a skeletally immature freestyle footballer

We report the case of a skeletally immature freestyle footballer who presented with avulsion fracture of the lesser trochanter. The patient had precursor symptom before onset during a ball juggling. Nonoperative treatment demonstrated good clinical course. This new sporting activity involves kicking the ball continuously, typically with both the hip and the knee in flexion. This repetitive movement might cause continuous stretching stress of the iliopsoas muscle at the apophysis of the lesser trochanter, causing disruption at this site. This new sporting activity in this age cohort may have higher prevalence of this type of injury due to its unique repetitive hip flexion movement.

Physical therapists referring patients to physicians: a review of case reports and series

STUDY DESIGN

Descriptive.

BACKGROUND

An important role for physical therapists in the healthcare delivery system is to recognize when patient referral to a physician or other healthcare provider is indicated. Few studies exist describing physical therapists' evaluative and diagnostic processes leading to patient referral to a physician.

OBJECTIVE

To summarize published patient case reports that described physical therapist/patient episodes of care that resulted in the referral of the patient to a physician and a subsequent diagnosis of medical disease.

METHODS

A literature search identified 78 case reports describing physical therapist referral of patients to physicians with subsequent diagnosis of a medical condition. Two evaluators reviewed the cases and summarized (1) how and when patients accessed physical therapy services, (2) timing of patient referral to a physician, (3) resultant medical diagnoses, (4) physical therapists' role in referral of patients for diagnostic testing, and (5) relevant patient symptom description, health history, review of systems, and physical examination findings.

RESULTS

Fifty-eight (74.4%) of 78 patients had been referred to a physical therapist by their physician, while the remaining 20 patients accessed physical therapy services via direct access. The patients' primary presenting symptoms included pain (n = 60), weakness (n = 4), tingling/numbness (n = 2), or a combination (n = 12). Patient referrals to a physician occurred at the initial physical therapy session in 58 (74.4%) of 78 cases. A majority of patient referrals to a physician (n = 65) were related to primary presenting symptoms, including manifestations inconsistent with physician diagnosis, recent worsening without cause, unusual accompanying symptoms such as fatigue and/or weakness, and inadequate response to treatment. Resultant diagnoses included neuromusculoskeletal disorders (n = 53; fractures and tumors most common), visceral disorders (n = 14; cardiovascular involvement most common), and medication-related disorders (n = 3).

CONCLUSIONS

This review of published patient case reports provides numerous examples of physical therapists using effective multifactorial screening strategies for referred and direct-access patients, leading to timely patient referrals to physicians. The therapist-initiated patient referral to a physician led to subsequent diagnosis of a wide range of conditions and pathological processes.

Isolated lesser trochanter fracture in adults: an early indicator of tumor infiltration

We report on a case of isolated lesser trochanter fracture, without associated trauma, secondary to pulmonary adenocarcinoma metastasis. Treatment consisted in resection-reconstruction by megaprosthesis. This form of isolated fracture is rare, and results from infiltration of the trochanteric area by a malignant tumoral process, which is usually metastatic.

Dance-Related Injury

Although dance medicine has derived extensive knowledge from sports medicine, some aspects covered in the practice of dance medicine are unique to this field. Acute and overuse injuries must be analyzed within the scope of associated mechanisms of injury, mainly related to the practice of specific dance techniques. Even though most available medical literature concerning dance medicine is specific to ballet-related conditions, many of the concepts covered here and in other articles can be helpful in the treatment and diagnosis of participants in other dance disciplines. Continued research is expanding the knowledge on injury patterns of different dance disciplines. It is the experience of dance practitioners that dancers are quite in touch with their bodies; thus, when their ailments are systematically analyzed, and underlying cause can usually be identified. In this sense, it is evident that the principles of dance medicine and rehabilitation allow the practitioner to arrive at a diagnosis and treat the underlying causes to prevent reinjury, ameliorate sequelae from injury, and minimize residual deficits after injury.

Diagnostic imaging and differential diagnosis in 2 case reports

STUDY DESIGN

Retrospective resident's case reports.

BACKGROUND

In today's healthcare setting, it is important for physical therapists to recognize when diagnostic imaging is necessary--as well as know how to interpret the results of these tests--to assist in the clinical decision-making process. Two cases are presented that illustrate how a physical therapist, credentialed to request and review diagnostic imaging, effectively and efficiently utilized multiple forms of diagnostic imaging to assist in his differential diagnosis and clinical decision making.

DIAGNOSIS

The first case report describes the differential diagnostic process for a 33-year-old active duty military paratrooper who had sustained trauma to his neck. His history was consistent with a C6 radiculopathy, which was confirmed by a neurological screening examination. Radiographs requested by the physical therapist revealed an anterolithesis of C5 on C6, with a possible fracture. An orthopedic surgeon was consulted and further diagnostic testing via magnetic resonance imaging revealed a large disc herniation at C5-6, with spinal cord compression, as well as a C5 vertebral body fracture with nearly perched facets at C5 on C6. The patient was subsequently referred to a neurosurgeon and underwent an emergency C5-6 fusion that afternoon. The second case report describes the differential diagnosis of a 20-year-old active-duty soldier referred for rehabilitation with a diagnosis of a distal fibula stress fracture. Previous treatment by the referring provider included 3 months of rest and anti-inflammatory medications. Physical examination of the patient revealed a marked decrease in ankle inversion with a firm end feel. This was not consistent with the diagnosis established by the referring provider. Subsequent radiographs requested by the physical therapist and a computed tomography scan requested by a podiatrist revealed synostosis of the middle facet of the talocalcaneal joint with an apparent fracture line. The patient subsequently underwent a subtalar arthrodesis.

DISCUSSION

In these cases the physical therapist requested imaging needed for appropriate management, despite the patient having previously seen a primary care provider. In both examples, the physical therapist successfully identified abnormalities prior to a radiologist or other physician reviewing the results. This avoided delay in definitive management of the patients' problems. It is imperative that physical therapists understand when diagnostic imaging is necessary to assist in the differential diagnosis of patients. Likewise, it is important for physical therapists to be competent in interpreting the results of these tests. When not in a direct access physical therapy environment, a physical therapist should understand when diagnostic imaging tests are indicated. This facilitates working with the entire health care team to acquire necessary tests in an appropriate timeframe.

Medical and rehabilitation issues in classical ballet

Classical ballet is a demanding professional occupation, with participants who are often underserved in terms of accurate diagnosis and appropriate comprehensive medical care. The view that follows is designed to be as global and insightful as published to date. Specific rehabilitation considerations, dance mechanics, idiosyncratic differential diagnosis, and personality and equipment issues are discussed, and a rational view of dogma is presented.

Hip arthroscopy in the adolescent and pediatric athlete

The current literature offers only sparse reports of the use of hip arthroscopy in the pediatric patient injured during athletics. In contrast, the role of this technique in the diagnosis and treatment of multiple childhood hip conditions including pyarthrosis, Legg-Calvé-Perthes disease, slipped capital femoral epiphysis, coxa vara, juvenile chronic arthritis, chondrolysis, and avascular necrosis is well described. The application of this relatively uncommon technique to the young athlete has only recently become more attractive. The ability to examine and treat traumatic intra-articular pathology with minimal morbidity and prompt recovery is mandated by the young age of these patients and their demanding activity levels. Hip arthroscopists are now beginning to correlate preoperative physical exam findings and history with diagnosis and expectations for outcome. As our combined experience with this technique grows, the specific indications for its use in the young athlete become increasingly better defined. In pediatric and adolescent patients, the new onset of hip pain should warrant a high level of suspicion for the more common causes of pain such as infection, Legg-Calvé-Perthes disease, slipped capital femoral epiphysis, or developmental dysplasia. When these have been evaluated, further differential diagnosis should include labral tears, loose bodies, synovitis, and chondral lesions. As this review begins to elucidate, these conditions are amenable to arthroscopic evaluation and treatment. At this time, the presence of reproducible mechanical symptoms after a twisting or axial loading injury during athletics should prompt the orthopaedic surgeon to consider arthroscopic examination of the hip if conservative therapy fails. Satisfying and reproducible results have been achieved when using hip arthroscopy within these parameters.

Hip and groin injuries in athletes

Although athletic injuries about the hip and groin occur less commonly than injuries in the extremities, they can result in extensive rehabilitation time. Thus, an accurate diagnosis and well-organized treatment plan are critical. Because loads of up to eight times body weight have been demonstrated in the hip joint during jogging, presumably even greater loads can occur during vigorous athletic competition. The available imaging modalities are effective diagnostic tools when selected on the basis of a thorough history and physical examination. Considerable controversy exists as to the cause and optimal treatment of groin pain in athletes, or the so-called "sports hernia." There has also been significant recent attention focused on intraarticular lesions that may be amenable to hip arthroscopy. This article briefly reviews several common hip and groin conditions affecting athletic patients and highlights some newer topics.
