Proton Pump Inhibitors, But Not H2-receptor Antagonists, Are Associated With Incident Fractures Among Kidney Transplant Recipients.

BACKGROUND: Fractures are a common and burdensome problem among kidney transplant recipients (KTRs). Proton pump inhibitors (PPIs) are frequently used after kidney transplantation and have been associated with increased fracture risk in the general population. This study aimed to determine whether PPI use is associated with incidence of major fractures in KTRs. METHODS: Using the Wisconsin Allograft Recipient Database, we identified 155 KTRs with a major fracture that occurred at least 12 months after transplantation. Controls were selected using incidence-density sampling. Use of PPIs and histamine 2-receptor antagonists (H2RA) during the year before the index date were identified. RESULTS: A total of 155 cases were matched to 685 controls. Within 1 year before the index date, 68% of cases and 52% of controls used a PPI, and 16% of cases and 11% of controls used an H2RA. PPI use was associated with higher incidence of major fractures in unadjusted analysis (odds ratio [OR], 2.4; 95% CI, 1.6-3.5) and in adjusted analyses controlling for demographic and transplant-related covariates and use of corticosteroids, bisphosphonates, vitamin D and calcium supplements (OR, 1.9; 95% CI, 1.2-3.1). H2RA use was not associated with incidence of major fractures in adjusted analyses (OR, 1.0; 95% CI, 0.5-1.8). The associations between PPI use and fractures remained similar in analyses limited to spine and hip fractures. CONCLUSIONS: Use of PPIs, but not H2RAs, is associated with a higher risk of major fractures among KTRs. Clinicians should individualize PPI use in KTRs, evaluating the risks and benefits of prescribing and continuing PPIs in KTRs.

A new finite element based parameter to predict bone fracture.

Dual Energy X-Ray Absorptiometry (DXA) is currently the most widely adopted non-invasive clinical technique to assess bone mineral density and bone mineral content in human research and represents the primary tool for the diagnosis of osteoporosis. DXA measures areal bone mineral density, BMD, which does not account for the three-dimensional structure of the vertebrae and for the distribution of bone mass. The result is that longitudinal DXA can only predict about 70% of vertebral fractures. This study proposes a complementary tool, based on Finite Element (FE) models, to improve the DXA accuracy. Bone is simulated as elastic and inhomogeneous material, with stiffness distribution derived from DXA greyscale images of density. The numerical procedure simulates a compressive load on each vertebra to evaluate the local minimum principal strain values. From these values, both the local average and the maximum strains are computed over the cross sections and along the height of the analysed bone region, to provide a parameter, named Strain Index of Bone (SIB), which could be considered as a bone fragility index. The procedure is initially validated on 33 cylindrical trabecular bone samples obtained from porcine lumbar vertebrae, experimentally tested under static compressive loading. Comparing the experimental mechanical parameters with the SIB, we could find a higher correlation of the ultimate stress, σULT, with the SIB values (R2adj = 0.63) than that observed with the conventional DXA-based clinical parameters, i.e. Bone Mineral Density, BMD (R2adj = 0.34) and Trabecular Bone Score, TBS (R2adj = -0.03). The paper finally presents a few case studies of numerical simulations carried out on human lumbar vertebrae. If our results are confirmed in prospective studies, SIB could be used-together with BMD and TBS-to improve the fracture risk assessment and support the clinical decision to assume specific drugs for metabolic bone diseases.

State of the art forensic techniques reveal evidence of interpersonal violence ca. 30,000 years ago.

The Cioclovina (Romania) calvaria, dated to ca. 33 cal ka BP and thought to be associated with the Aurignacian lithic industry, is one of the few relatively well preserved representatives of the earliest modern Europeans. Two large fractures on this specimen have been described as taphonomic modifications. Here we used gross and virtual forensic criteria and experimental simulations on synthetic bone models, to investigate their nature. Both forensic trauma pattern analysis and experimental models exclude a postmortem origin for the Cioclovina fractures. Rather, they indicate two incidents of blunt force trauma, the second clearly inflicted with a club-like object. The magnitude and extent of the lesions and the lack of signs of healing indicate a fatal injury. The Upper Paleolithic period is noted for intensified technological innovation, increased symbolic behavior, and cultural complexity. We show that the behavioural repertoire of the earliest modern Europeans also comprised violent inter-personal interactions and murder.

Bone fractures from generalized convulsive seizures and status epilepticus-A systematic review.

OBJECTIVE: We present a systematic review of the literature regarding types and anatomic distribution of fractures in association with generalized convulsive status epilepticus (GCSE) and convulsive seizures in adult patients accompanied by an illustrative case of a patient with GCSE and diffuse postictal pain from underlying bone fractures. METHODS: The library search engines PubMed and EMBASE were screened systematically using predefined search terms. All identified articles written in English were screened for eligibility by two reviewers. The preferred reporting items for systematic reviews and meta-analyses guidelines were followed. RESULTS: The screening of 3145 articles revealed 39 articles meeting the inclusion criteria. Among all fractures, bilateral posterior fracture-dislocations of the shoulders were reported most frequently (33%), followed by thoracic and lumbar vertebral compression fractures (29%), skull and jaw fractures (8%), and bilateral femoral neck fractures (6%). Risk factors for seizure-related fractures are seizure severity, duration of epilepsy, the use of antiseizure drugs known to decrease bone density, and a family history of fractures. Based on these findings, a three-step screening procedure is proposed to uncover fractures in the postictal state. All studies were retrospective without standardized screening methods for seizure-associated fractures resulting in a very low level of evidence and a high risk of bias. SIGNIFICANCE: Posterior fracture-dislocations of the shoulders, thoracic and lumbar vertebral compression, fractures of the skull and jaw, and bilateral femoral neck fractures are most frequently reported. Preventive measures including bone densitometry, calcium/vitamin D supplementation, and bisphosphonate therapy should be reinforced in epilepsy patients at risk of osteoporosis. As long as the effect of standardized screening of fractures is not investigated, it is too early to integrate such a screening into treatment guidelines. In the meantime, clinicians are urged to heighten awareness regarding seizure-associated fractures, especially in patients with postictal pain, as symptoms can be unspecific and misinterpretation may impede rehabilitation.

Combined effects of four major geriatric syndromes on adverse outcomes based on Korean National Health Insurance claims data.

AIM: Geriatric syndromes are common among older individuals, and can affect their health and quality of life. The present study aimed to determine if combinations of geriatric syndromes affected adverse outcomes among older Koreans. METHODS: Korean national health insurance data were collected for a cohort of 5 058 720 individuals who were aged ≥65 years in 2008. The same data source was used to follow these individuals until 2015. Diagnostic codes were used to assess four major geriatric syndromes (delirium, fall-related fractures, incontinence and pressure ulcers) and adverse outcomes (mortality and nursing home institutionalization). RESULTS: The prevalence of geriatric syndromes was 0.3% for delirium, 3.49% for fall-related fractures, 1.08% for incontinence and 0.82% for pressure ulcers. All four geriatric syndromes were associated with increased risks of institutionalization (adjusted hazard ratio [aHR] 2.18, 95% CI 2.08-2.17 for delirium; aHR 1.59, 95% CI 1.58-1.60 for fall-related fractures; aHR 1.43, 95% CI 1.41-1.44 for incontinence; and aHR 2.51, 95% CI 2.47-2.55 for pressure ulcers) and increased risks of mortality (aHR 2.13, 95% CI 2.08-2.17 for delirium; aHR 1.41, 95% CI 1.40-1.42 for fall-related fractures; aHR 1.09, 95% CI 1.07-1.10 for incontinence; and aHR 3.23, 95% CI 3.20-3.27 for pressure ulcers). The aHR for institutionalization were 1.64 (95% CI 1.63-1.65) for one geriatric syndrome, 2.40 (95% CI 2.35-2.44) for two coexisting geriatric syndromes and 2.56 (95% CI 2.35-2.74) for three coexisting geriatric syndromes. The aHR for mortality were 1.52 (95% CI 1.51-1.53) for one geriatric syndrome, 2.36 (95% CI 2.32-2.40) for two coexisting geriatric syndromes and 2.90 (95% CI 2.72-3.09) for three coexisting geriatric syndromes. CONCLUSIONS: Delirium, fall-related fractures, incontinence and pressure ulcers were associated with increased risks of institutionalization and mortality. The magnitude of these risks increased with increasing numbers of coexisting geriatric syndromes. Geriatr Gerontol Int 2018; 18: 1463-1468.

Turning the backbone into an ankylosed concrete-like structure: Case report.

RATIONALE: Progressive restriction of the spinal bio-mechanics is not-uncommon deformity encountered in spine clinics. Congenital spinal fusion as seen in Klippel-Feil-anomaly, progressive non-infectious anterior vertebral fusion, and progressive spinal hyperostosis secondary to ossification of the anterior longitudinal spinal ligament are well delineated and recognized. PATIENT CONCERNS: A 24-year-old girl has history of osteoporosis since her early childhood, associated with multiple axial and appendicular fractures and scoliosis. Recently she presented with episodes of severe back pain, spinal rigidity/stiffness with total loss of spine biomechanics. DIAGNOSES: She was provisionally diagnosed as having osteogenesis imperfecta and was investigated for COL1A1/A2 mutations which have been proven to be negative. Autosomal recessive type of osteogenesis imperfecta was proposed as well, no mutations have been encountered. A homozygous for CTSA gene mutation, the gene associated with Galactosialidosis was identified via whole exome sequencing (Next-Generation Sequencing projects) has been identified. INTERVENTIONS: Early in her life she had a history of frequent fractures of the long bones since she was 4 years which was followed by vertebral fractures at the age of 12 years. She manifested lower serum 25OH-D levels and were associated with lower LS-aBMD Z-scores with higher urinary bone turnover indexes (urinary NTX/Cr). OUTCOMES: Lysosomal storage diseases (LSD) have a strong correlation with the development of osteoporosis. LSD causes skeletal abnormalities results from a lack of skeletal remodeling and ossification abnormalities owing to abnormal deposition of GAGs (impaired degradation of glycosaminoglycans ) in bone and cartilage. 3D reconstruction CT scan of the spine showed diffuse hyperostosis of almost the entire spine (begins at the level of T4- extending downwards to involve the whole thoraco-lumbar and upper part of the sacrum) with total diffuse fusion of the pedicles, the transverse and articular processes, the laminae and the spinous processes. LESSONS: This is the first clinical report of adult patient with a history of osteoporosis and fractures with the late diagnosis of Galactosialidosis. Osteogenesis imperfecta (autosomal dominant and recessive) were the first given diagnoses which proven negative. The pathophysiology of the spine ankylosis in our current patient and its correlation with LSD, antiresorptive medications, vitamin D3 and supplemental calcium is not fully understood. Therefore, further studies are needed to elucidate this sort of correlation.

Isolated fracture of the handle of the malleus is a rare cause of conductive hearing loss and represents a challenge for the otolaryngologist in terms of past medical history, diagnostics, and therapy.

[Geriatric trauma centers from the idea to implementation. What has been achieved?]. / Alterstraumazentren von der Idee bis zur Umsetzung. Was wurde erreicht?

The geriatric trauma working party, a subgroup of the German Society of Trauma Surgery (Deutsche Gesellschaft für Unfallchirurgie, DGU), focuses on the challenges of geriatric fractures, which are steadily increasing due to demographic changes. Inherent comorbidities implicate perioperative complications leading to loss of mobility and endangered independence followed by an increased burden on the social services. An interdisciplinary approach is required. The geriatric trauma working party defined criteria for interdisciplinary treatment and comprehensive care as well as early rehabilitation in interdisciplinary geriatric fracture centers. By passing an independent audit process these centers can achieve certification as a geriatric trauma center DGU (AltersTraumaZentrum DGU). Certified centers can participate in a recently established geriatric fracture registry which includes an internationally consented data set. Audit and registry enable centers to acquire an international benchmark, ensure permanent improvement in quality and allow participation in health services research.

Examination and treatment of scaphoid fractures and pseudarthrosis.

BACKGROUND: About 2,000 patients annually incur a fractured scaphoid in Norway. Assessment and diagnosis can be difficult, and fractures are overlooked. Scaphoid fractures have traditionally been cast-immobilised, but for the last decade screw fixing has been used increasingly, and offers hope of a higher healing frequency and improved function. Some scaphoid fractures are not diagnosed in the acute phase and some do not heal after treatment. Patients may then end up with painful pseudarthrosis. The purpose of this article is to provide an overview of the assessment, treatment and outcomes of scaphoid fractures. METHOD: The article is based on literature searches in PubMed and the authors' own clinical experience. RESULTS: Primary diagnosis of scaphoid fractures and subsequent plaster cast immobilisation yield very good clinical results. Surgery should be limited to displaced fractures, fractures forming part of more extensive wrist injuries and exceptional other cases. Results comparable a quality equivalent to cast immobilisation are achieved by experienced surgeons in this area. Untreated scaphoid fractures often result in painful pseudarthrosis with subsequent abnormal position of the carpal bones and secondary arthrosis. This outcome can be counteracted by surgery on old fractures with bone grafting, internal fixation and cast immobilisation. INTERPRETATION: Norwegian procedures for treating scaphoid fractures/pseudarthrosis are consistent with internationally documented good practice. Assessment of wrist pain following falls can be improved by conducting clinical tests for scaphoid fracture and radiology with four wrist projections. In the event of clinical suspicion, but no X-ray findings, the patient should be referred for a CT or MRI scan.

[Imaging of diabetic osteopathy]. / Bildgebung der diabetischen Osteopathie.

CLINICAL ISSUE: Diabetic bone diseases are more than just osteoporosis in patients with diabetes mellitus (DM): a relatively high bone mineral density is paired with a paradoxically high risk of fragility fractures. Diabetics exhibit low bone turnover, osteocyte dysfunction, relative hypoparathyroidism and an accumulation of advanced glycation end products in the bone matrix. Besides typical insufficiency fractures, diabetics show a high risk for peripheral fractures of the lower extremities (e.g. metatarsal fractures). The correct interdisciplinary assessment of fracture risks in patients with DM is therefore a clinical challenge. STANDARD RADIOLOGICAL METHODS: There are two state of the art imaging methods for the quantification of fracture risks: dual energy X-ray absorptiometry (DXA) and quantitative computed tomography (QCT). Radiography, multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) are suitable for the detection of insufficiency fractures. METHODICAL INNOVATIONS AND PERFORMANCE: Novel research imaging techniques, such as high-resolution peripheral quantitative computed tomography (HR-pQCT) provide non-invasive insights into bone microarchitecture of the peripheral skeleton. Using MR spectroscopy, bone marrow composition can be studied. Both methods have been shown to be capable of discriminating between type 2 diabetic patients with and without prevalent fragility fractures and thus bear the potential of improving the current standard of care. Currently both methods remain limited to clinical research applications. PRACTICAL RECOMMENDATIONS: DXA and HR-pQCT are valid tools for the quantification of bone mineral density and assessment of fracture risk in patients with DM, especially if interpreted in the context of clinical risk factors. Radiography, CT and MRI are suitable for the detection of insufficiency fractures.

Bone Health in Adolescence.

Osteoporosis occurs during childhood and adolescence as a heritable condition such as OI, with acquired disease (eg, IBD), or iatrogenically as a result of high-dose glucocorticoid therapy. However, the number of children affected by osteoporosis during youth is small compared to the numbers who will develop osteoporosis in adulthood. Prevention of adult osteoporosis requires that an optimal environment for the achievement of peak bone mass be established during the growing years. Detection of low BMD can be achieved using modalities such as DXA and pQCT. Standard radiologic studies, especially vertebral radiography, may also be helpful in children and adolescents at high risk for osteoporosis. It is critical to the development of healthy bones that adolescents have proper nutrition with adequate calcium and vitamin D intake and that they participate in regular physical activity (especially weight-bearing exercise). In the recent past, the dual goals of proper nutrition and exercise were not being achieved by many, if not most, adolescents. Those caring for adolescents should strive to educate teens and their families on the importance of dietary calcium and vitamin D as well as advocate for supportive environments in schools and communities that foster the development of healthy habits with regard to diet and exercise. In order to help identify the population at risk for osteoporosis, a bone health screen with assessment of calcium intake and determination of family history of adult osteoporosis (hip fracture, kyphosis) should be a routine part of adolescent health care. Universal screening of healthy adolescents with serum 25OHD levels is not recommended. Adolescents with conditions associated with reduced bone mass should undergo bone densitometry or other studies as a baseline, and BMD should be monitored at intervals no more frequently than yearly. Although controversy remains regarding the optimum dose of vitamin D for treatment of osteoporosis, all would agree that vitamin D should be provided, and in doses somewhat higher than previously recommended. Excessive vitamin D should be avoided. The use of bisphosphonates is recommended for the treatment of OI, as well as for treatment of select children with severe osteoporosis associated with chronic conditions that lead to frequent or painful fragility fractures. In such situations, bisphosphonates should be prescribed only in the context of a comprehensive clinical program with specialists knowledgeable in the management of osteoporosis in children.

Optimizing bone health in children and adolescents.

The pediatrician plays a major role in helping optimize bone health in children and adolescents. This clinical report reviews normal bone acquisition in infants, children, and adolescents and discusses factors affecting bone health in this age group. Previous recommended daily allowances for calcium and vitamin D are updated, and clinical guidance is provided regarding weight-bearing activities and recommendations for calcium and vitamin D intake and supplementation. Routine calcium supplementation is not recommended for healthy children and adolescents, but increased dietary intake to meet daily requirements is encouraged. The American Academy of Pediatrics endorses the higher recommended dietary allowances for vitamin D advised by the Institute of Medicine and supports testing for vitamin D deficiency in children and adolescents with conditions associated with increased bone fragility. Universal screening for vitamin D deficiency is not routinely recommended in healthy children or in children with dark skin or obesity because there is insufficient evidence of the cost-benefit of such a practice in reducing fracture risk. The preferred test to assess bone health is dual-energy x-ray absorptiometry, but caution is advised when interpreting results in children and adolescents who may not yet have achieved peak bone mass. For analyses, z scores should be used instead of T scores, and corrections should be made for size. Office-based strategies for the pediatrician to optimize bone health are provided. This clinical report has been endorsed by American Bone Health.

Bone densitometry in children and adolescents.

PURPOSE OF REVIEW: Abnormalities in bone health are increasingly recognized in the pediatric population. Although the methodologies for assessing bone mineral density were originally developed for adults, great strides have been made in recent years, improving their applicability to children. Understanding these technologies, their interpretation, utility, and limitations is critical when assessing a child or adolescent with a suspected abnormality in bone mineral density. RECENT FINDINGS: Improved normative databases that address some of the confounding variables in the growing and maturing child have solidified dual-energy X-ray absorptiometry as the preferred method for the assessment of bone mineral density in children. Consensus statements by expert panels now provide specific guidance to clinicians seeking to evaluate children with fractures or at risk for fractures. Although still primarily a research tool, continued development of quantitative computed tomography applications in pediatrics suggests there may be a complementary role for clinical use in the future. SUMMARY: In the child or adolescent with a significant fracture history or a potential for fractures because of an underlying cause, clinicians now have guidelines and normative data to better focus their evaluation. Likewise, researchers can use this information to improve clinical trial design and interpretation of results.

When something is not quite right: an ankle sprain.

Ankle sprains are a common musculoskeletal injury in sport. Older people are increasingly participating in sports such as running. The specificities of musculoskeletal injuries in older people pose a different diagnostic challenge from that in young people participating in the same activities. A clinical case is presented of a 64-year-old patient diagnosed with a grade 1, plantar flexion/inversion ankle sprain that was later diagnosed as a quite different and rare injury. Fractures of the fibular malleolus, talar neck and dome are possible differential diagnoses for an ankle sprain, as are talar dome chondral defects. Response to treatment may help to guide the diagnostic procedure when pain persists after appropriate treatment.

Soft tissue knee injury with concomitant osteochondral fracture is associated with higher degree of acute joint inflammation.

BACKGROUND: Osteochondral fractures are often seen on magnetic resonance imaging (MRI) of acutely injured knees, but their existence has gained little interest because of a lack of knowledge of their relation to treatment options and outcome. It is not clear whether acute phase synovial fluid (SF) concentrations of cartilage and bone markers and proinflammatory cytokines are different between traumatically injured knees with or without osteochondral fracture. HYPOTHESIS: Acutely injured knees with an osteochondral fracture, particularly fractures with disrupted cortical bone, have higher concentrations of bone markers and cytokines than do knees without an osteochondral fracture. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: Synovial fluid (hemarthrosis) was aspirated (median 1 day after injury) and 1.5-T MRI was performed (median 8 days after injury) in the acutely injured knee of 98 individuals (26% women; mean age, 23 years). As visualized on MRI, 39% knees had an osteochondral fracture with disrupted cortical bone, 30% had an osteochondral fracture with intact cortical bone, and 32% did not have an osteochondral fracture. Concentrations of sulfated glycosaminoglycan, ARGS aggrecan, cartilage oligomeric matrix protein, osteocalcin, secreted protein acidic and rich in cysteine (SPARC), osteopontin and proinflammatory cytokines (interleukin [IL]-1ß, IL-6, IL-8, and tumor necrosis factor [TNF]-α) were analyzed. RESULTS: After adjusting for days between injury and SF aspiration, age at injury, and sex, knees with any osteochondral fracture (with or without disrupted cortical bone) had significantly higher SF concentrations of TNF-α (median [interquartile range (IQR)] = 9 [7-12] pg/mL vs. 7 [5-14] pg/mL; P = .013), whereas knees with an osteochondral fracture with disrupted cortical bone had significantly higher SF concentrations (medians [IQRs]) of SPARC (492 [328-754] ng/mL vs. 407 [140-685] ng/mL; P = .030), IL-8 (278 [148-628] pg/mL vs. 138 [67-413] pg/mL; P = .028), and TNF-α (11 [7-15] pg/mL vs. 7 [5-14] pg/mL; P = .004) compared with knees without an osteochondral fracture. CONCLUSION: In acutely injured knees with hemarthrosis, a concomitant osteochondral fracture with disrupted cortical bone is associated with a higher degree of joint inflammation.

Tea consumption didn't modify the risk of fracture: a dose-response meta-analysis of observational studies.

BACKGROUND: Fractures are important causes of healthy damage and economic loss nowadays. The conclusions of observational studies on tea consumption and fracture risk are still inconsistent. The objective of this meta-analysis is to determine the effect of tea drinking on the risk of fractures. METHODS: A comprehensive literature search was conducted in PubMed, Embase and reference lists of the relevant articles. Observational studies that reported an estimate of the association between tea drinking and incidence of fractures were included. A meta-analysis was conducted by the STATA software. RESULTS: A total of 9 studies involving 147,950 individuals that examined the association between tea consumption and risk of fractures were included in this meta-analysis. The odds risks (ORs) with 95% confidence intervals (CIs) were pooled using a random-effects model. The pooled OR of 9 observational studies for the tea consumption on risk of fracture was 0.89 (95% CI, 0.78-1.04). In the subgroup analyses, no significant association was detected in neither cohort studies (n=3; OR, 0.97; 95% CI, 0.89-1.06) nor case-control studies (n=6; OR, 0.91; 95% CI, 0.70-1.19), respectively. No significant association was detected in the dose-response meta-analysis. CONCLUSIONS: Tea consumption might not be associated with the risk of fractures. The following large-sample and well-designed studies are required to confirm the existing conclusions.

Therapeutic peritoneal lavage with warm saline solution as an option for a critical hypothermic trauma patient.

INTRODUCTION: In this paper, we present the case of a 63-year-old woman, who was found in her flat lying unconscious on the floor for an unknown time. At the time of admission, her core temperature was 24 °C and ventricular fibrillation was detected on the electrocardiogram (ECG). Because of the unstable conditions, the persistent nonperfusing cardiac rhythm and the dramatically inhibited coagulation cascade, a peritoneal lavage connected to a rapid infuser was performed for rewarming, instead of using a transportable heart-lung machine and a haemodialysis device. After a prolonged cardiopulmonary resuscitation (CPR), the patient could be transferred to the intensive care unit (ICU) in a stable condition. After 40 days in the ICU, recovery was fast, and another month of treatment later, she could be discharged back home without any discomfort. CONCLUSION: This report illustrates the successful use of the peritoneal lavage for rewarming a severely hypothermic patient without any extracorporeal rewarming device. Furthermore, it can be used in nearly every hospital if the necessary equipment is affordable. It is demonstrated that this technique is able to provide good outcomes for all victims of accidental hypothermia.

National Athletic Trainers' Association position statement: conservative management and prevention of ankle sprains in athletes.

OBJECTIVE: To present recommendations for athletic trainers and other allied health care professionals in the conservative management and prevention of ankle sprains in athletes. BACKGROUND: Because ankle sprains are a common and often disabling injury in athletes, athletic trainers and other sports health care professionals must be able to implement the most current and evidence-supported treatment strategies to ensure safe and rapid return to play. Equally important is initiating preventive measures to mitigate both first-time sprains and the chance of reinjury. Therefore, considerations for appropriate preventive measures (including taping and bracing), initial assessment, both short- and long-term management strategies, return-to-play guidelines, and recommendations for syndesmotic ankle sprains and chronic ankle instability are presented. RECOMMENDATIONS: The recommendations included in this position statement are intended to provide athletic trainers and other sports health care professionals with guidelines and criteria to deliver the best health care possible for the prevention and management of ankle sprains. An endorsement as to best practice is made whenever evidence supporting the recommendation is available.

Rehabilitation of an osteochondral fracture using blood flow restricted exercise: a case review.

OBJECTIVES: In this case review we report on a bodybuilder who used a practical model of blood flow restriction (BFR) training to successfully rehabilitate himself following an injury to his right knee. RESULTS: The patient originally thought he had torn his meniscus however repeat radiographs and magnetic resonance imaging (MRI) confirmed an osteochondral fracture. The patient initially sought out a low load alternative to help with the maintenance of skeletal muscle mass. However, following rehabilitation with low load BFR resistance training, radiographs indicated that the bone had begun to heal suggesting that this type of training may also benefit bone. CONCLUSIONS: In conclusion, this case review provides evidence that practical BFR using knee wraps can serve as an effective stimulus during rehabilitation from a knee injury.
