Injuries in amateur horse racing (point to point racing) in Great Britain and Ireland during 1993-2006.

OBJECTIVES: To provide a breakdown of injury incidence from amateur jump racing (also known as point to point racing) in Great Britain and Ireland during 1993-2006 and to compare the injury epidemiology with professional horse racing in Great Britain, Ireland and France. DESIGN: Retrospective review. SETTING: Great Britain and Ireland. PARTICIPANTS: Amateur jockeys. MAIN OUTCOME MEASURES: Injury rates. RESULTS: Injury data suggest that point to point racing is more dangerous from an injury point of view than professional jump racing, which has previously been shown to be more dangerous than flat racing. Amateur jockeys have more falls than their professional counterparts, and this in turn puts them at greater risk of sustaining more serious injuries. CONCLUSIONS: Amateur (point to point) jockeys represent a sporting population that previously has been little studied. They represent a group at high risk of injury, and hence formal injury surveillance tracking and counter measures for injury prevention are recommended.

Consensus statement on injury definitions and data collection procedures in studies of football (soccer) injuries.

BACKGROUND: Variations in definitions and methodologies have created differences in the results and conclusions obtained from studies of football (soccer) injuries; this has made interstudy comparisons difficult. PROCEDURE: An Injury Consensus Group was established under the auspices of Fédération Internationale de Football Association Medical Assessment and Research Centre. Using a nominal group consensus model approach, a working document that identified the key issues related to definitions, methodology, and implementation was discussed by members of the group during a 2-day meeting. After this meeting, iterative draft statements were prepared and circulated to the members of the group for comment before the final consensus statement was produced. RESULTS: Definitions of injury, recurrent injury, severity, and training and match exposures in football, together with criteria for classifying injuries in terms of location, type, diagnosis, and causation are proposed. Proforma for recording players' baseline information, injuries, and training and match exposures are presented. Recommendations are made on how the incidence of match and training injuries should be reported and a checklist of issues and information that should be included in published reports of studies of football injuries is presented. CONCLUSIONS: The definitions and methodology proposed in the consensus statement will ensure that consistent and comparable results will be obtained from studies of football injuries.

High school rugby players' understanding of concussion and return to play guidelines.

OBJECTIVE: To document high school players' understanding and attitudes towards concussion return to play guidelines. METHODS: A questionnaire based survey was performed of national high school rugby players as to their knowledge of existing concussion return to play guidelines. RESULTS: A total of 600 male players were surveyed, and 477 responded (response rate 80%). Half (237/477) were aware of concussion guidelines, and 60% (288/477) identified the mandated stand down period that is part of the regulations governing rugby football. Players obtained their information primarily from: teachers/coaches (239 responses), medical personnel (200), and other players (116). Of those players who suspected that they had been concussed (296/477, 62%), only 66 returned to play after medical clearance. CONCLUSIONS AND IMPLICATIONS: This sample of high school players showed a limited knowledge of the concussion guidelines covering their sport, and even when concussed did not follow recommended protocols. This indicates the need for an increased focus on player education.

Equestrian injuries.

OBJECTIVE: This chapter reviews the current evidence for the epidemiology of pediatric equestrian injuries. DATA SOURCES: The relevant literature was searched through the use of MEDLINE (1966-2004) and SPORT DISCUS (1975-2004) searches, hand searches of journals and reference lists and discussions with experts and sporting organizations worldwide. Keywords and Mesh headings used in all searches included horse racing, children, pediatric injuries, sports injuries, equestrian injuries and sports trauma. MAIN RESULTS: Limited data exist on the epidemiology of pediatric equestrian injuries. Most studies note the high preponderance of females with a peak incidence at approximately 14 years of age. This is likely to reflect the higher rate of female riders. The two most common horse riding-related injuries are long bone fractures and head injury. Although most injuries occur during recreational riding, approximately 15% of injuries occur in nonriding activities such as feeding, handling, shoeing and saddling. CONCLUSIONS: While there is little knowledge of injury demographics or the efficacy of prevention countermeasures in this field, it is likely that injuries will continue to occur. The major challenge in reducing pediatric equestrian injuries is the formal scientific demonstration that the various proposed injury prevention measures are effective. With the majority of equestrian injuries happening during unsupervised leisure riding, the prospect of injury prevention is limited.

Preparticipation assessment for head injury.

OBJECTIVE: To determine the evidence base for recommendations regarding the pre-participation screening for head injury. DATA SOURCES: The relevant literature was searched through the use of Medline (1966 to 2004), Google and Sport Discus (1975 to 2004) searches, hand searches of journals and reference lists and discussions with experts and sporting organisations worldwide. DATA SYNTHESIS/METHODS: Consensus recommendations are summarized. No formal statistical analysis is presented RESULTS: Although pre-participation examinations are widely performed, there are no evidence-based guidelines to direct physicians as to the minimum requirements for the baseline assessment of head injury. CONCLUSIONS: Expert consensus would suggest that a baseline neuropsychological examination, preferably using a computerised test battery, should be performed in order to guide return to play following subsequent concussive injuries. In addition, there are important medicolegal considerations in regard to the value of a documented assessment both at the start and end of an athlete's career with any team.

Snowboarding injuries : current trends and future directions.

Snowboarding has become one of the premier alpine sports. The past decade has seen the popularity of snowboarding increase dramatically and the recent Winter Olympic Games at Salt Lake City, USA, showcased the strong visual appeal of the sport and the youth-oriented lifestyle and culture that accompanies it. The injury profile of the sport has also undergone change along with technological advances in boot and binding systems and the changing demographics of the sports participants. Central to the development of injury-prevention strategies is knowledge of the profile of injuries that occur, understanding those who are at particular risk and, if possible, the biomechanical factors involved in each injury type. Snowboarding was initially considered a dangerous, uncontrolled, alpine sport - an opinion based on little or no scientific evidence. That evidence has rapidly grown over the past decade and we now know that snowboard injury rates are no different to those in skiing; however, the injury profile is different. The purpose of this review is to give some perspective to the current snowboard injury literature. It discusses not only the demographic profile of those injured and the type of injuries that occur, but also gives some insight into the progress that has occurred in determining the impact of specific prevention strategies, such as splints to prevent injuries to the wrist/forearm. The next decade will also see a greater understanding of the biomechanical forces involved in snowboard injuries, which may well impact on future technological advances. As the literature indicates, however, some things will not change, e.g. injuries are more likely to occur in beginners and lessons need to be reinforced as a fundamental aspect of any injury-prevention strategy.

CogSport: reliability and correlation with conventional cognitive tests used in postconcussion medical evaluations.

OBJECTIVE: To determine the repeatability of a computerized cognitive test designed to monitor recovery from concussion and assist team physicians make return to play decisions (CogSport). To determine the correlation between CogSport and two conventional neuropsychological tests. DESIGN: Prospective, serial investigation of cognitive function. SETTING: Professional and semi-professional Australian Football clubs and a university affiliated research institute in Melbourne, Australia. PARTICIPANTS: Three-hundred healthy young adults, including 240 elite athletes. MAIN OUTCOME MEASURES: Intra-class correlation (ICC) coefficients for CogSport performance measures administered serially. ICC between CogSport performance measures and conventional neuropsychological tests. Normative data for CogSport performance measures. RESULTS: Measures of psychomotor function, decision making, working memory and learning were highly reliable. Some measures also displayed high correlations with conventional neuropsychological tests of information processing and attention. Preliminary normative data is described. CONCLUSIONS: CogSport is a highly reliable cognitive function test when administered to healthy young adults and elite athletes. CogSport measures similar cognitive functions as conventional tests used commonly in concussion research.

Hip joint pathology: clinical presentation and correlation between magnetic resonance arthrography, ultrasound, and arthroscopic findings in 25 consecutive cases.

BACKGROUND: The hip joint is becoming increasingly recognized as a source of groin pain and, in the authors' experience, buttock and low back pain. OBJECTIVES: To determine the range of pathologic diagnoses, clinical presentation, and the correlation between magnetic resonance arthrographic, ultrasonographic, and arthroscopic findings in the hip joint. METHODS: We prospectively studied 25 consecutive hip arthroscopies to determine the range of pathologic diagnoses, clinical presentation, and the correlation between magnetic resonance arthrographic, ultrasonographic, and arthroscopic findings. RESULTS: All of the hips arthroscoped had pathology. Back pain and hip pain were the 2 most common presentations. The only consistently positive clinical test result was a restricted and painful hip quadrant compared with the contralateral hip. Of the 17 patients whose flexion, abduction, external rotation (FABER) test results were reported at the time of examination, 15 (88%) were positive, and 2 (12%) negative. Plain radiographs were normal in all patients. All but 1 patient underwent magnetic resonance arthrography. Although specificity of 100% was achieved in our study, the sensitivity was significantly lower, with a relatively high number of false negatives. Hip arthroscopy proved the definitive diagnostic procedure for intraarticular pathology. CONCLUSIONS: Hip pathology, particularly labral pathology, may be more common than has been previously recognized. In those patients with chronic groin and low back pain, a high index of suspicion should be maintained. Clinical signs of a painful, restricted hip quadrant and a positive FABER test result should suggest magnetic resonance arthrography in the first instance, but a negative magnetic resonance image should not preclude hip arthroscopy if there is high clinical suspicion of hip joint pathology.

Treatment of recurrent concussion.

The management of an athlete with recurrent concussions, whether persistently symptomatic or not, remains anecdotal. Currently, there are no evidence-based guidelines upon which a team physician can advise the athlete. All doctors involved in athlete care need to be aware of the potential for medicolegal problems if athletes are inappropriately returned to sport prematurely or, in the case of professional athletes, held out of sport or retired on the basis of nonscientific recommendations. This paper discusses such issues.

Nerve entrapments of the lower leg, ankle and foot in sport.

Exercise-related leg pain is a common and yet difficult management problem in sports medicine. There are many common causes of such symptoms including stress fractures and muscle compartment syndromes. There are also a number of less common but important conditions including popliteal artery entrapment and nerve entrapment syndromes. Even for an astute clinician, distinction between the different medical causes may be difficult given that many of their presenting features overlap. This review highlights the common clinical presentations and raises a regional approach to the diagnosis of the neurogenic symptoms. In part, this overlapping presentation of different pathological conditions may be due to a common aetiological basis of many of these conditions namely, fascial dysfunction. The same fascial restriction that predisposes to muscle compartment syndromes may also envelop the neurovascular structures within the leg resulting in either ischaemic or neurogenic symptoms. For many athletes with chronic exercise-related leg pain, combinations of such problems often coexist suggesting a more widespread fascial pathology. In our clinical experience, we often label such patients as 'fasciopaths'; however, the precise pathophysiological basis of this fascial problem remains to be elucidated. This review discusses the various nerve entrapment syndromes in the lower limb that may result in exercise-related leg pain in the sporting context. The anatomy, clinical presentation, investigation, medical management and surgical treatment are discussed at length for each of the syndromes. It is clear from clinical experience that the outcome of surgical management of such syndromes fares much better where a clear dermatomal pain distribution is present or where focal weakness and/or sensory symptoms appropriate for the nerve are present. In many situations, however, nonspecific leg pain or vague nonlocalising sensory symptoms are present and in such situations, alternative diagnoses must be considered and investigated appropriately. As mentioned above, many different pathologies may coexist in the lower limb and may be a source of confusion for the clinician or alternatively may be the reason for poor treatment outcomes.
