Effectiveness of implementation strategies for increasing clinicians' use of five validated imaging decision rules for musculoskeletal injuries: a systematic review.

BACKGROUND: Strategies to enhance clinicians' adherence to validated imaging decision rules and increase the appropriateness of imaging remain unclear. OBJECTIVE: To evaluate the effectiveness of various implementation strategies for increasing clinicians' use of five validated imaging decision rules (Ottawa Ankle Rules, Ottawa Knee Rule, Canadian C-Spine Rule, National Emergency X-Radiography Utilization Study and Canadian Computed Tomography Head Rule). DESIGN: Systematic review. METHODS: The inclusion criteria were experimental, quasi-experimental study designs comprising randomised controlled trials (RCTs), non-randomised controlled trials, and single-arm trials (i.e. prospective observational studies) of implementation interventions in any care setting. The search encompassed electronic databases up to March 11, 2024, including MEDLINE (via Ovid), CINAHL (via EBSCO), EMBASE (via Ovid), Cochrane CENTRAL, Web of Science, and Scopus. Two reviewers assessed the risk of bias of studies independently using the Cochrane Effective Practice and Organization of Care Group (EPOC) risk of bias tool. The primary outcome was clinicians' use of decision rules. Secondary outcomes included imaging use (indicated, non-indicated and overall) and knowledge of the rules. RESULTS: We included 22 studies (5-RCTs, 1-non-RCT and 16-single-arm trials), conducted in emergency care settings in six countries (USA, Canada, UK, Australia, Ireland and France). One RCT suggested that reminders may be effective at increasing clinicians' use of Ottawa Ankle Rules but may also increase the use of ankle radiography. Two RCTs that combined multiple intervention strategies showed mixed results for ankle imaging and head CT use. One combining educational meetings and materials on Ottawa Ankle Rules reduced ankle injury imaging among ED physicians, while another, with similar efforts plus clinical practice guidelines and reminders for the Canadian CT Head Rule, increased CT imaging for head injuries. For knowledge, one RCT suggested that distributing guidelines had a limited short-term impact but improved clinicians' long-term knowledge of the Ottawa Ankle Rules. CONCLUSION: Interventions such as pop-up reminders, educational meetings, and posters may improve adherence to the Ottawa Ankle Rules, Ottawa Knee Rule, and Canadian CT Head Rule. Reminders may reduce non-indicated imaging for knee and ankle injuries. The uncertain quality of evidence indicates the need for well-conducted RCTs to establish effectiveness of implementation strategies.

Booster visits in the management of the acute musculoskeletal injuries: Transforming care to improve outcomes-A perspective review.

The current healthcare delivery system for patients with acute musculoskeletal injury is failing. Current rehabilitation management of acute musculoskeletal injury typically includes physical therapy, focused on management of impairments, with an eventual transition to functional activities and release to prior level of function. At that point, formal physical therapy is often discontinued, despite the knowledge that a high percentage of patients fail to maintain preinjury level of activity and often reduce participation in regular physical activity. Further, for those who attempt to return to prior levels of pivoting and cutting activities, there is a high second injury rate. The long-term human experience is compromised by the current model of care which terminates at the point of transition to activity. This model of care fails to meet the continued needs of these patients and may result in long term deficits and potential disability. Extended care models include intermittent follow up visits after discharge from an acute episode of care and have been efficacious and cost effective in some patient populations with musculoskeletal conditions. Specifically, a type of extended care model, labeled "booster sessions," represents an opportunity to provide structured, intermittent care to assist in a smooth transition back to function, following an acute episode of care and promote a healthier life outcome. This perspective review will discuss the opportunity to transform acute musculoskeletal care to booster visit care model in an attempt to develop a more efficacious and cost-effective system of care which could be generalizable to all musculoskeletal conditions.

Musculoskeletal injuries during trail sports: Sex- and age-specific analyses over 20 years from a national injury database.

INTRODUCTION: Musculoskeletal (MSK) injuries in US trail sports are understudied as trail sport popularity grows. This study describes MSK injury patterns among hikers, trail runners, and mountain bikers from 2002 through 2021 and investigates MSK injury trends acquired during mountain sports. METHODS: The National Electronic Injury Surveillance System (NEISS) was used to identify US emergency department (ED) patients from 2002-2021 (inclusive) who endured MSK injuries during hiking, trail running, or mountain biking. Injury rates and national estimates were calculated across demographics. RESULTS: 9835 injuries were included (48.4% male, 51.6% female). Injuries increased over time, with 1213 from 2002-2005 versus 2417 from 2018-2021. No sex differences existed before 2010, after which female injury rates exceeded those of males. The following findings were statistically significant, with P<0.05: females endured more fractures and strains/sprains; males endured more lacerations; concussions and head injuries were higher among those <18 y; dislocations and strains/sprains were higher for 18 to 65 y; fractures were higher for >65 y; <18 y had high mountain-biking and low running rates; 18 to 65 y had high running rates; and >65 y had low biking and running rates. Although all diagnoses increased in number over time, no significant differences existed in the proportion of any given diagnosis relative to total injuries. CONCLUSIONS: MSK injuries during trail sports have increased since 2002. Males endured more injuries until 2009, after which females endured more. Significant sex and age differences were found regarding injury diagnosis and body parts. Further studies are needed to confirm these trends and their causes.

Ergonomic risks and problems of the musculoskeletal system for physiotherapists: comparison of employees in the fields of pediatric and adult care.

Objectives. The aim of this study is to compare the ergonomic risk levels, musculoskeletal complaints and quality of life of physiotherapists (PTs) according to their field of work. Methods. A total of 107 volunteer PTs participated in the study, whose information was recorded. Ergonomic risk levels were determined using rapid entire body assessment (REBA). Complaints about the musculoskeletal system of PTs were evaluated with the Cornell musculoskeletal discomfort questionnaire (CMDQ) and quality of life was evaluated by the Nottingham health profile. Results. PTs who worked with pediatric patients (Grouppediatric; n = 47) were younger (p<0.001). PTs who worked with adult patients (Groupadult; n = 60) had a higher daily number of patients (p<0.001). The REBA score did not make a difference between the groups (p = 0.379). The difference was found in the upper back region of the CMDQ (p<0.05). There was no difference between groups for quality of life (p>0.05). Conclusions. Grouppediatric may be working in ergonomically demanding positions, although there is no statistical difference. The injury sites of the musculoskeletal system can differ. However, the reflection of musculoskeletal system problems on quality of life does not show any difference between the groups of PTs.

Umbrella review of musculoskeletal injury burden in dancers: implication for practice and research.

BACKGROUND: Dancers are susceptible to injury. Nevertheless, injury epidemiology research in dancers is inconsistent. Furthermore, ballet dancing has dominated the huge body of reviews analyzing the epidemiology of musculoskeletal injuries in a variety of artistic dance forms, making it challenging to acquire a thorough, comprehensive, and understandable reporting of the available data. PURPOSE: The overview and reanalysis of dancers' musculoskeletal pain and injury load across artistic dance forms. STUDY DESIGN: Systematic review of systematic reviews and meta-analysis. METHODS: A search was conducted online for literature written in English using PubMed and Google Scholar (2012-2021). The data gathered was then analyzed using predetermined qualifying criteria. RESULTS: 12 reviews were determined to be qualified, the majority of which had moderate to low confidence and raised concerns about bias based on JBI-URARI and ROBIS. The prevalence of dance-related musculoskeletal injuries ranged from 26% to 84% in any artistic dancers and 42% to 343% in ballet dancers. The incidence was less than 5 per 1000 dance hours in both groups, with lower extremities and back being the commonly reported sites. Reviews themselves stated that the quality of the reviews was often poor. Due to the study's heterogeneity and methodological inconsistency, data pooling and meta-analysis were not possible. CONCLUSION: The current review emphasizes the gaps and restrictions in the dance epidemiology literature that make it challenging to quantify and report a single overall injury rate for dancers. These results underline the need for better primary investigations and evidence synthesis. As injury epidemiology is a critical component of the overall injury-prevention puzzle, there is a need for standardization in future research, particularly with active and prospective injury surveillance, injury classification, injury evaluation, and injury reporting. LEVEL OF EVIDENCE: Systematic Review, Level III.

Oral analgesic for musculoskeletal injuries in children: A systematic review and network meta-analysis.

OBJECTIVE: Pain in pediatric musculoskeletal (MSK) injuries can lead to increased anxiety, fear, and avoidance of medical care, making analgesic management critical. Therefore, we evaluated analgesic efficacy and adverse effects to select the optimal analgesic agent in pediatric patients with MSK injuries. METHODS: Four databases were searched from inception to March 2023 for peer-reviewed, open randomized controlled trials (RCTs). Inclusion criteria were: (1) trials with RCT design, (2) children aged 1 month-18 years with MSK injury, (3) outpatient setting, (4) interventions and control, (5) primary outcome of pain score at 60 and 120 min and secondary outcome of adverse effects, and (6) full-text and peer-reviewed articles. Two reviewers screened, extracted data, and assessed the risk of bias. A frequentist random-effects network meta-analysis (NMA) was performed. Certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation working group approach. RESULTS: We included eight trials comprising 1645 children. Ibuprofen was significantly associated with pain reduction at 120 min, compared with acetaminophen (SMD 0.31 [95% CI 0.11-0.51]; moderate certainty) and opioids (SMD 0.34 [95% CI 0.20-0.48]; moderate certainty). Compared with opioids alone, ibuprofen-opioid combination was significantly associated with pain reduction at 120 min (SMD 0.19 [95% CI 0.03-0.35]). No significant differences were found in pain interventions at 60 min. Ibuprofen had statistically fewer adverse events than opioids (RR, 0.54 [95% CI 0.33-0.90]; moderate certainty) and ibuprofen with opioids (RR 0.47 [95% CI 0.25-0.89]; moderate certainty). In terms of limitations, the eight RCTs included had relatively small sample sizes; only two were high-quality RCTs. CONCLUSIONS: Our NMA found ibuprofen to be the most effective and least adverse analgesic in pediatric patients with MSK injuries.

Early Results of Orthopaedic Trauma and Anemia: Conservative Versus Liberal Transfusion Strategy.

INTRODUCTION: The purpose of this study was to determine whether it is safe to use a conservative packed red blood cell transfusion hemoglobin threshold (5.5 g/dL) compared with a liberal transfusion threshold (7.0 g/dL) for asymptomatic patients with musculoskeletal-injured trauma out of the initial resuscitative period. METHODS: This was a multicenter, prospective, nonblinded, randomized study done at three level 1 trauma centers. One hundred patients were enrolled. One patient was inappropriately enrolled, withdrawn from the study, and excluded from analysis leaving 99 patients (49 liberal and 50 conservative) with 30-day follow-up. After initial resuscitation, patients were enrolled and randomized to either a liberal or a conservative transfusion strategy. This strategy was followed throughout the index hospitalization. The primary outcome of the study was infection. Superficial infection was defined as clinical diagnosis of cellulitis or other superficial infection treated with oral antibiotics only. Deep infection was defined as clinical diagnosis of fracture-related infection requiring IV antibiotics and/or surgical débridement. RESULTS: Ninety-nine patients were successfully followed for 30 days with 100% follow-up during this time. Seven infections (14%) occurred in the liberal group and none in the conservative group ( P < 0.01). Five deep infections (10%) occurred in the liberal group and none in the conservative group ( P = 0.03). Three superficial infections (6%) occurred in the liberal and none in the conservative group, which was not a significant difference ( P = 0.1). No difference was observed in length of stay between groups. DISCUSSION: Transfusing young healthy asymptomatic patients with orthopaedic trauma for hemoglobin <7.0 g/dL increases the risk of infection. No increased risk of anemia-related complications was identified with a conservative transfusion threshold of 5.5 g/dL. DATA AVAILABILITY AND TRIAL REGISTRATION NUMBERS: Data are available on request. IRB protocol number is 1402557771. This study was registered with Clinicaltrials.gov identifier NCT02972593. LEVEL OF EVIDENCE: Level 2, unblinded prospective randomized multicenter study.

Musculoskeletal Injury Prevalence, Pain Perception, and Physical Activity Level Among Brazilian Strength and Cross-Training Practitioners.

In this study, we sought to determine the prevalence of musculoskeletal injuries, perceived pain, and physical activity level among Brazilian practitioners of strength training (ST) and functional fitness (FF). Participants were 311 men and women who trained in 10 FF training centers and seven ST gyms. Each participant completed surveys of the prevalence of musculoskeletal injuries, their pain perception, and their physical activity level. A chi square test was used to analyze associations between groups and distributions of injuries. When any significant difference was observed, the difference score was analyzed through the adjusted residual values. Fisher's exact test was used to determined the associations between musculoskeletal injury prevalence and training modality (FF and ST) and between musculoskeletal injury prevalence and practice frequency (times/wk). To measure the magnitude of association between variables, the Phi coefficient was calculated for 2x2 associations and Cramer's V was used whenever the distributions were outside this standard. When the dependent variable presented a dichotomous characteristic, an Odds Ratio (OR) was calculated with a confidence interval of 95%. We found a higher musculoskeletal injury prevalence in the axial skeleton (n = 52; 83.88%) in FF practitioners and in the lower limbs of ST practitioners (n = 9; 52.96%). When the physical activity level cutoff point was set at 300 minutes per week, there was a significant relationship between physical activity and training modality (p = 0.005). There was also a significant association between pain perception and musculoskeletal injury (p < 0.001). Clinical follow-up was a protective factor to being injured (OR = 0.18; CI = 0.06-0.49), and, even after multivariate analysis this significant association was maintained (OR = 0.03; CI = 0.01 - 0.08). Thus, FF practitioners reported more musculoskeletal injuries than STs, and follow-up medical or physical therapy was a protective factor to these injuries. FF practitioners also had a higher level of weekly physical activity weekly than ST practitioners. Functional fitness practitioners may be at a higher risk of injuries than those who participate in traditional strength training.

Olympic Class Sailing Injuries and Illness: A 15-Year Study of a World Cup Regatta Venue.

INTRODUCTION: Olympic class sailing injuries are a minimally researched topic. Our study includes 15 y of data from medical coverage of the Miami venue during the Sailing World Cup. The objective was to examine the nature of Olympic class sailing injuries and illnesses during competition. METHODS: The records of the medical clinic encounters of a World Cup Sailing regatta were reviewed. Summary statistics and nominal categorized data regarding demographics, onset, mechanism, nature of condition, and referral were collected. RESULTS: There were 740 clinic encounters, ranging from 20 to 70 annually. Five hundred fifty-five (75%) were musculoskeletal in nature, and 184 (25%) were related to medical concerns. Twelve athletes were referred to the emergency department (ED), averaging <1 per year. However, 6 (50%) of the ED referrals came from NACRA 17, 49er, and 49er F-X classes, representing a 16% ED referral rate by fleet per year. In contrast, the remainder of the classes had a 0.04% ED referral rate. The lumbar spine, cervical spine, and foot/ankle were the most common body regions treated. Laser Radial sailors had 71(10%) visits, the most per class. Coaches and staff represented 59 (8%) visits. CONCLUSIONS: Olympic class sailing venue medical coverage should be equipped to treat a variety of acute and chronic injuries and illnesses among athletes as well as coaches and staff. Overall, rates of ED or other off-site referrals are low but higher for 49er, 49er F-X, and North American Catamaran Racing Association (NACRA)-17 classes.

Deep vein thrombosis and validation of the Caprini risk assessment model in Chinese orthopaedic trauma patients: a multi-center retrospective cohort study enrolling 34,893 patients.

BACKGROUND: The risk of venous thromboembolism among orthopaedic trauma patients is high, but prevalence of deep vein thrombosis (DVT) remains unknown. In addition, the Caprini risk assessment model (RAM) score in orthopaedic trauma patients is undetermined in previous research. This study is aimed to determine the incidence of DVT and then validate the Caprini RAM in orthopaedic trauma patients. METHODS: This is a retrospective cohort study enrolling orthopaedic trauma inpatients from seven tertiary and secondary hospitals during a 3-year period (from April 1, 2018 through April 30, 2021). Caprini RAM scores were assessed by experienced nurses on admission. The patients with suspected DVT were verified through duplex ultrasonography by qualified radiologists, and then prospectively followed once a year after discharge. RESULTS: In total, 34,893 patients were enrolled in our study. The Caprini RAM identified 45.7% of patients at low risk (Caprini score 0-2), 25.9% at medium risk (3-4), and 28.3% at high risk (5-6), highest risk (7-8), and superhigh risk (> 8). Patients with Caprini score > 5 were likely to be older, female, and with longer length of hospital stay. Moreover, 8695 patients had received ultrasonography to detect DVT. The prevalence of DVT was determined to be 19.0% [95% confidence interval (CI) 18.2-19.9%], which significantly increased with Caprini score. The area under curve of the Caprini RAM for DVT was 0.77 (95% CI 0.76-0.78) with a threshold of 4.5. Furthermore, 6108 patients who had received ultrasonography completed the follow-up. DVT patients had a hazard ratio of 1.75 (95% CI 1.11-2.76; P = 0.005) in the mortality, compared to non-DVT ones. Caprini scores were significantly associated with increase in the mortality [odds ratio (OR) 1.14; 95% CI 1.07-1.21; P < 0.001]; DVT remained an independent effect (OR 1.5; 95% CI 1.02-2.26; P = 0.042). CONCLUSIONS: The Caprini RAM may be valid in Chinese orthopaedic trauma patients. Prevalence of DVT and higher Caprini score were significantly associated with increased all-cause mortality among orthopaedic trauma patients after discharge. Further study is warranted to explore the causes of higher mortality in patients with DVT.

Establishing a consensus on research priorities in orthopaedic trauma within South Africa.

BACKGROUND: Musculoskeletal (MSK) injuries are one of the leading causes of disability worldwide. Despite improvements in trauma-related morbidity and mortality in high-income countries over recent years, outcomes following MSK injuries in low- and middle-income countries, such as South Africa (SA), have not. Despite governmental recognition that this is required, funding and research into this significant health burden are limited within SA. This study aims to identify research priorities within MSK trauma care using a consensus-based approach amongst MSK healthcare practitioners within SA. METHOD: Members from the Orthopaedic Research Collaboration in Africa (ORCA), based in SA, collaborated using a two round modified Delphi technique to form a consensus on research priorities within orthopaedic trauma care. Members involved in the process were orthopaedic healthcare practitioners within SA. RESULTS: Participants from the ORCA network, working within SA, scored research priorities across two Delphi rounds from low to high priority. We have published the overall top 10 research priorities for this Delphi process. Questions were focused on two broad groups-clinical effectiveness in trauma care and general trauma public health care. Both groups were represented by the top two priorities, with the highest ranked question regarding the overall impact of trauma in SA and the second regarding the clinical treatment of open fractures. CONCLUSION: This study has defined research priorities within orthopaedic trauma in South Africa. Our vision is that by establishing consensus on these research priorities, policy and research funding will be directed into these areas. This should ultimately improve musculoskeletal trauma care across South Africa and its significant health and socioeconomic impacts.

Epidemiology of Musculoskeletal Injuries Among Naval Special Warfare Personnel.

BACKGROUND: Musculoskeletal injuries (MSIs) are an important cause of morbidity in the military, especially among Special Forces. The aim of this analysis was to describe MSIs among two groups of Naval Special Warfare (NSW) personnel-Special Warfare Combatant-Craft Crewman (SWCC) Operators and Crewman Qualification Training (CQT) students. METHODS: In this cross-sectional study, we describe self-reported MSIs that occurred during a one-year period and the calculated financial costs of MSIs. Group comparisons were conducted using Fisher's exact tests and independent samples t tests. RESULTS: Data were available for 142 SWCC Operators (26.9 ± 5.9 years, 1.8 ± 0.1 meters, 85.4 ± 10.4 kilograms) and 187 CQT students (22.8 ± 3.2 years, 1.8 ± 0.2 meters, 81.4 ± 8.9 kilograms). The one-year cumulative MSI incidence was significantly lower among SWCC Operators (21.1%) compared to CQT students (37.4%, p = 0.002). The most common anatomic location for MSIs was the lower extremity (SWCC: 50.0% of MSIs, CQT: 66.3%). Physical training was the predominant activity when MSIs occurred (SWCC: 31.6%, CQT: 77.6%). The lifetime cost of all the MSIs included in the analysis was approximately $580,000 among 142 SWCC Operators and $1.2 million among 187 CQT students. CONCLUSION: MSIs, especially those affecting the lower extremity and occurring during physical training, cause considerable morbidity and financial burden among NSW personnel. Many of the musculoskeletal injuries are to musculotendinous tissue, which typically results from tissue overload or inadequate recovery. Further investigation of the preventable causes of these MSIs and development of a customized, evidence-based MSI prevention program is required to reduce the burden of these MSIs.

No pain, no gain: The military overtraining hypothesis of musculoskeletal stress and injury.

The purpose of this manuscript is to present a model of military overtraining and subsequent injury, discharge, and disability. Military training and combat operations are physically and physiologically demanding, placing great strain on the musculoskeletal system of warfighters. Non-battle musculoskeletal injuries (MSKI) are common and present a serious threat to operational readiness in today's military. MSKI risk stratification and prevention are an active area of research and is steeped in the background of sports science. Here, a model is proposed that incorporates the theory of General Adaptation Syndrome to describe how military training stressors may exceed that of training in traditional athletics and may induce sub-optimal training stressors. Positive feedback loops are discussed to explain how military overtraining (MOT) creates a system of ever-increasing stressors that can only be fully understood in the greater context of all environmental factors leading to overtraining. The Military Overtraining Hypothesis (MOTH) is proposed as a model that encapsulates the elevated MSKI risk in combat arms and other operational military personnel as an effort to broaden understanding of multifactorial military MSKI etiologies and as a tool for researchers and commanders to contextualize MSKI research and risk mitigation interventions.

The effect of rapid weight loss on sports injury in elite taekwondo athletes.

OBJECTIVES: The purpose of this study was to reveal the relationship of injury patterns between normal training period and weight loss period in Korea elite taekwondo athletes. METHODS: Since 2021, data for elite taekwondo athletes have been collected prospectively by the Korean Training Institute, there were 102 male and 95 female. The data were classified by sex, weight class, injury location, injuries during the normal training and weight loss periods. The χ2 test was used to compare groups. The injury incidence rates were calculated as the number of injuries per 1,000 hours of training. RESULTS: A total of 703 injuries were recorded during normal training, and total of 149 injuries were recorded during the weight loss period. Taekwondo athletes showed a higher incidence of during the weight loss period than during the normal training period (3.66 VS 6.88; p < 0.001). The body parts affected by injury differed significantly between the normal training period and weight loss period (p = 0.033). Injury to the lower extremities or to the head and neck was relatively higher during the normal training period, while injury to the trunk and upper extremities was relatively higher during the weight loss period. Muscle, ligament, and bone injuries were common during both the normal training and weight loss periods. Level I injuries were relatively more frequent during normal training, while level II and III injuries were relatively more frequent during weight loss (p < 0.001). CONCLUSION: Rapid weight loss is related to the injury patterns in taekwondo athletes. Injury incidence rate increases during rapid weight loss periods. Moreover, the injury site and injury severity depend on during normal training and during the weight loss period.

Changes in Thoroughbred speed and stride characteristics over successive race starts and their association with musculoskeletal injury.

BACKGROUND: Certain stride characteristics have been shown to affect changes in biomechanical factors that are associated with injuries in human athletes. Determining the relationship between stride characteristics and musculoskeletal injury (MSI) may be key in limiting injury occurrence in the racehorse. OBJECTIVES: This study aimed to determine whether changes in race day speed and stride characteristics over career race starts are associated with an increased risk of MSI in racehorses. STUDY DESIGN: Case-control study. METHODS: Speed, stride length, and stride frequency data were obtained from the final 200 m sectional of n = 5660 race starts by n = 584 horses (case n = 146, control n = 438). Multivariable joint models, combining longitudinal and survival (time to injury) analysis, were generated. Hazard ratios and their 95% confidence intervals (CI) are presented. RESULTS: The risk of MSI increased by 1.18 (95% CI 1.09, 1.28; P < 0.001) for each 0.1 m/s decrease in speed and by 1.11 (95% CI 1.02, 1.21; P = 0.01) for each 10 cm decrease in stride length over time (career race starts). A more marked rate of decline in speed and stride length was observed approximately 6 races prior to injury. Risk of MSI was highest early in the horse's racing career. MAIN LIMITATIONS: Only final sectional stride characteristics were assessed in the model. The model did not account for time between race starts. CONCLUSIONS: Decreasing speed and stride length over multiple races is associated with MSI in racehorses. Monitoring stride characteristics over time may be beneficial for the early detection of MSI.

Epidemiology of Musculoskeletal Injuries in the Navy: A Systematic Review.

Objectives: This study aimed to critically review the results of recent studies that investigated the epidemiology of noncombat-related musculoskeletal injuries (MSIs) in the Navy. Methods: A systematic search was conducted of three major databases (Pubmed, Embase, and Cochrane) to identify epidemiological studies on MSIs in the Navy. Study selection and risk of bias assessment were conducted. Results: The overall prevalence of MSIs ranged from 12.69% to 48.81%. And the prevalence of head and face injuries, upper extremity injuries, spine injuries, chest injuries, and lower extremity injuries were 0.11%-0.66%, 0.53%-11.47%, 0.75%-12.09%, 0.43%-0.95%, and 0.4%-21.17%, respectively. For the specific MSIs, the incidence ranged from 0.03/1000 person-years to 32.3/1000 person-years in the Navy and Marines. The ankle-foot, lumbopelvic, knee and lower leg, and shoulder were identified as the most frequent location for MSIs. Conclusion: This systematic review summarized that the Navy population had a high prevalence of MSIs. And different risk factors for MSIs varied from different anatomic locations. This systematic review also provided valuable information on MSIs for sports medicine specialists.

Monitoring the beautiful adapted game: a 3-year prospective surveillance study of injuries in elite English Para football.

Para football is currently played in impairment-specific formats by thousands of people worldwide. To date, there have been no prospective longitudinal injury surveillance studies. This study aimed to implement a prospective injury surveillance study within elite English Para football and analyse the injury risk within the England Blind and Cerebral Palsy (CP) squads. Match and training injury data based on a 'time loss' definition were collected and analysed for each squad including incidence per 1,000 player hours, severity, injury location and associated event of injury. Injury incidence were lower in training than matches (CP 67.6/1000 player match hours (CI 33.8-135.2) and 5.7/1000 training hours (CI 3.8-8.7) and Blind 44.0/1000 player match hours (CI 26.1-74.3) and 5.5/1000 training hours (CI 3.5-8.6). Training injuries were more severe than match injuries across both squads (CP median 12 days lost in matches and 16 training and Blind median days 5 matches and 12 training). 73% Blind and 74% CP footballer injuries were to the lower limb and 17% head and neck equally across both Para football squads. 'Muscle and tendon injuries' (51%) represented the greatest proportion of injuries for CP footballers, and 'joint (non-bone)/ligament injuries' (43%) for Blind footballers. Collaboration and implementation of higher quality surveillance methodology and data collection in Para sport with greater athlete numbers are needed to inform injury prevention strategies.

Rehabilitation After Pediatric and Adolescent Knee Injuries.

According to epidemiology studies, the majority of youth sports injuries presenting to primary care, athletic trainers, and emergency departments impact the musculoskeletal system. Both acute and overuse knee injuries can contribute to sports attrition before high school. Effective rehabilitation of knee injuries ensures a timely return to sports participation and minimizes the negative physical, psychological, and social consequences of becoming injured. The following article provides rehabilitation and returns to play strategies for postsurgical and nonsurgical injuries of the young athlete's knee.

Does Military High-speed Boat Slamming Cause Severe Injuries and Disability?

BACKGROUND: Many operators of professional high-speed boats suffer severe, acute, and permanent injuries caused by slamming-induced hull impacts. As the number of professional high-speed boats and their speed capabilities increase, operators are reporting increasing numbers and severity of injuries. However, the actual incidence rate of acute injuries and the prevalence of chronic musculoskeletal disorders are still unknown. QUESTIONS/PURPOSES: We sought to investigate, among professional high-speed boat operators, (1) the self-reported incidence rate of impact-induced injuries, (2) the most common types of injuries or injury locations, (3) what impact characteristics were reported, and (4) the prevalence of self-reported sick leave, disability, and medical or orthopaedic treatment. METHODS: This study was an internet-based survey among retired military high-speed boat operators. The survey was given to members of the Combatant Craft Crewman Association online user group (360 members). Participants answered questions on demographics, service branch, service years and capacity, boat type, types of events, injury location, severity, pain, disability, and need for treatment. Values are presented as the mean ± SD and proportions. Incidence rates are presented as injuries per person-year. A total of 214 members of the Combatant Craft Crewman Association participated in the survey (213 men, mean age 50 ± 9 years, mean BMI 29 ± 4 kg/m 2 ). A total of 59% (214 of 360) of those we surveyed provided responses; all provided complete survey responses. RESULTS: The self-reported incidence rate of impact-induced injuries was 1.1 injuries per person-year served onboard. A total of 32% (775 of 2460) of respondents reported injuries that affected the back, and 21% (509 of 2460) reported injuries that affected the neck. Among those who responded, 33% (70 of 214) reported loss of consciousness onboard, and 70% (149 of 214) reported having experienced impaired capacity to perform their job onboard because of impact exposure. A total of 49% (889 of 1827) of the reported injuries were attributed to impacts containing lateral forces, 18% (333 of 1827) to frontal impacts, and 12% (218 of 1827) were attributed to purely vertical impacts. Finally, 67% (144 of 214) of respondents reported at least one occasion of sick leave from training or missions. Seventy-two percent (155 of 214) applied for a Veterans Affairs disability rating, and 68% (105 of 155) of these had a rating of 50% or higher. Additionally, 39% (84 of 214) reported having had surgery during active duty, and 34% (72 of 214) reported surgery after leaving active service. CONCLUSION: The results suggest that in the investigated military population, exposure to slamming-induced impacts onboard high-speed boats may cause more injuries than previously reported. Most reported injuries are musculoskeletal, but the high number of reported slamming-induced events of unconsciousness is concerning. LEVEL OF EVIDENCE: Level IV, prognostic study.
