Abstract
This article systematically reviews epidemiological studies on sports injury from 1977 to 2005 in which ankle injury was included. A total of 227 studies reporting injury pattern in 70 sports from 38 countries were included. A total of 201,600 patients were included, with 32,509 ankle injuries. Ankle injury information was available from 14,098 patients, with 11 847 ankle sprains. Results show that the ankle was the most common injured body site in 24 of 70 included sports, especially in aeroball, wall climbing, indoor volleyball, mountaineering, netball and field events in track and field. Ankle sprain was the major ankle injury in 33 of 43 sports, especially in Australian football, field hockey, handball, orienteering, scooter and squash. In sports injuries throughout the countries studied, the ankle was the second most common injured body site after the knee, and ankle sprain was the most common type of ankle injury. The incidence of ankle injury and ankle sprain was high in court games and team sports, such as rugby, soccer, volleyball, handball and basketball. This systematic review provides a summary of the epidemiology of ankle injury in sports.

Abstract
OBJECTIVES To explore gender differences in the cause of low back pain in a population of military personnel who are expected to undertake high levels of sport, exercise and physical military training. METHODS A prospective study of trained British soldiers, with symptomatic low back pain, referred to the Colchester Garrison Sports Injury and Rehabilitation Centre over a four year period. RESULTS The study demonstrates that 928 (17.8%) of the 5214 referrals were for new cases of low back pain. The incidence of low back pain in female soldiers is higher than their male counterparts with an odds ratio of 3.17 (95% CI 2.31 - 4.35) There was a highly significant cross gender difference in low back pain caused by activities in the followining categories: military physical traininong (OR 2.65, 95% CI 1.70 - 4.02), work or occupation (OR 2.49, 95% CI 1.56 - 3.87) and off-duty pursuits (OR 2.91, 95% CI 1.72 - 4.72). There was no cross gender difference in low back pain caused by sport, road traffic accidents or activities pre-dating military service. CONCLUSIONS Female soldiers are significantly more likely to suffer low back pain as a result of physical military training, their occupation, or off-duty activities. Sporting activities do not cause low back pain in women to a greater extent than men By demonstrating the scale of the problem and by determining of the cause of injury, it should now be possible to propose methods of effective intervention to reduce injury, implement those interventions and audit effectiveness.

Abstract
OBJECTIVES To record and analyse those injuries and conditions requiring referral to a military sports injury and rehabilitation centre over a three year period, with special reference to gender, type and site of injury, and the cause of the injury. METHODS A prospective study in which data on the gender, diagnosis, and cause of injury, of all patients referred to the Colchester Garrison Sports Injury and Rehabilitation Centre was recorded. All subjects were trained, serving soldiers in the British Army referred via their General Practitioner. RESULTS Low back pain (OR 2.71, p < 0.0001) and injuries to the hip, thigh and lower leg (OR 2.33, p < 0.0001) were more frequent in female soldiers. Military training (OR 4.62, p < 0.0001), work (OR 2.53, p < 0.0001), recreation (OR 2.39, p < 0.0001), and pre-existing conditions (OR 4.2, p < 0.0001) were the causes most commonly cited by female rather than male soldiers. There was no statistical gender difference for sport related or road traffic accident injuries. CONCLUSIONS Female soldiers are more likely to sustain an injury than their male counterparts. Specific injuries account for the majority of this difference. Military training, work, and recreation are more likely to be the cause of injury in the female soldier. Conditions existing prior to military service were also more common. There was no gender difference in the injuries caused by sport or road traffic accidents. These results may act as a basis for targeted intervention in order to reduce inequality without reducing overall training standards.

Abstract
OBJECTIVES To record and analyse the injuries and conditions requiring referral to the Colchester Garrison Sports Injury and Rehabilitation Centre over a three year period, with special reference to type and site of injury, aetiology, and outcome. METHODS An ongoing prospective study in which data on the diagnosis, cause of injury, and treatment of all patients referred to the Centre was coded and stored on a database. A total of seventeen variables were recorded. SUBJECTS All patients were trained, serving soldiers in the British Army referred via their General Practitioner to the Sports Injury and Rehabilitation Centre. RESULTS A total of 3921 referrals were made over the three-year period. The most common specific condition seen was low back pain (22.2%) followed by sprain of the ankle (15.1%). Lower limb conditions, both overuse and traumatic, accounted for over half (55.8%) of all referrals. Military training was the most common cause of all conditions (35.2%) followed by organised or personal sport (28.5%). In addition to medical treatment and physiotherapy, 30% of patients required formal rehabilitation. CONCLUSIONS This is the first full review of the data collected by the Sports Injury and Rehabilitation Centre. It defines the injury patterns for trained soldiers rather than military recruits. Low back pain is identified as a major cause of morbidity in this population. The review serves as a benchmark in the planning of injury prevention strategies and the establishment of future rehabilitation services.

Abstract
In sports medicine, a chronic overuse injury is defined as a long-standing or recurring orthopedic problem and pain in the musculoskeletal system, which started during exertion due to repetitive tissue microtrauma (1). Repetitive microtrauma, which is basically repeated exposure of the musculoskeletal tissue to low-magnitude forces, results in injury at the microscopic level, and no single acute trauma is normally involved in the pathogenesis of an overuse injury. In chronic tendon disorders, 'overuse' implies that the tendon has been strained repeatedly to 4-8% strain until unable to endure further tension, whereupon injury occurs (2). The structure of the tendon is disrupted micro- or macroscopically by this repetitive strain, i.e. collagen fibrers begin to slide past one another, causing break-age of their cross-linked structure, and denaturate; inflammation, edema and pain result. Thus, tendinitis, peritendinitis, tenosynovitis, insertion tendinitis, tendinous bursitis or apophysitis is the earliest clinically recognizable manifestation of overuse tendon injury (3).

Abstract
The purpose of this research was to identify possible predisposing neuromuscular factors for knee injuries, particularly anterior cruciate ligament tears in female athletes by investigating anterior knee laxity, lower extremity muscle strength, endurance, muscle reaction time, and muscle recruitment order in response to anterior tibial translation. We recruited four subject groups: elite female (N = 40) and male (N = 60) athletes and sex-matched nonathletic controls (N = 40). All participants underwent a subjective evaluation of knee function, arthrometer measurement of anterior tibial translation, isokinetic dynamometer strength and endurance tests at 60 and 240 deg/sec, and anterior tibial translation stress tests. Dynamic stress testing of muscles demonstrated less anterior tibial translation in the knees of the athletes (both men and women) compared with the nonathletic controls. Female athletes and controls demonstrated more anterior tibial laxity than their male counterparts and significantly less muscle strength and endurance. Compared with the male athletes, the female athletes took significantly longer to generate maximum hamstring muscle torque during isokinetic testing. Although no significant differences were found in either spinal or cortical muscle reaction times, the muscle recruitment order in some female athletes was markedly different. The female athletes appeared to rely more on their quadriceps muscles in response to anterior tibial translation; the three other test groups relied more on their hamstring muscles for initial knee stabilization.

Abstract
Participation in organized sports and fitness activity continues to increase in the United States. As a result, more acute bone and soft-tissue injuries are occurring in this patient population. Chronic overuse syndromes are also more common today. It is important for radiologists to understand the mechanism of injury so that they can properly approach the imaging of these patients. Although magnetic resonance imaging (MRI) is frequently the technique of choice, other imaging methods are also important and may, in certain cases, be preferred to MRI. In this review, we discuss extremity injuries by anatomic region. The spine is not included. A tailored imaging approach to each anatomic region and type of injury is discussed.

Abstract
Two-thirds of Achilles tendon injuries in competitive athletes are paratenonitis and one-fifth are insertional complaints (bursitis and insertion tendinitis). The remaining afflictions consist of pain syndromes of the myotendineal junction and tendinopathies. The majority of Achilles tendon injuries from sport occur in males, mainly because of their higher rates of participation in sport, but also with tendinopathies a gender difference is probably indicated. Athletes in running sports have a high incidence of Achilles tendon overuse injuries. About 75% of total and the majority of partial tendon ruptures are related to sports activities usually involving abrupt repetitive jumping and sprinting movements. Mechanical factors and a sedentary lifestyle play a role in the pathology of these injuries. Achilles tendon overuse injuries occur at a higher rate in older athletes than most other typical overuse injuries. Recreational athletes with a complete Achilles tendon rupture are about 15 years younger than those with other spontaneous tendon ruptures. Following surgery, about 70 to 90% of athletes have a successful comeback after Achilles tendon injury. Surgery is required in about 25% of athletes with Achilles tendon overuse injuries and the frequency of surgery increases with patient age and duration of symptoms as well as occurrence of tendinopathic changes. However, about 20% of injured athletes require a re-operation for Achilles tendon overuse injuries, and about 3 to 5% are compelled to abandon their sports career because of these injuries. Myotendineal junction pain should be treated conservatively. Partial Achilles tendon ruptures are primarily treated conservatively, although the best treatment method of chronic partial rupture seems to be surgery. Complete Achilles tendon ruptures of athletes are treated surgically, because this increases the likelihood of athletes reaching preinjury activity levels and minimises the risk of re-ruptures. Marked forefoot varus is found in athletes with Achilles tendon overuse injuries, reflecting the predisposing role of ankle joint overpronation. Athletes with the major stress in lower extremities have often a limited range of motion in the passive dorsiflexion of the ankle joint and total subtalar joint mobility, which seems to be predisposing factor for these injuries. Various predisposing transient factors are found in about one-third of athletes with Achilles tendon overuse injuries; of these, traumatic factors (mostly minor injuries) predominate. The typical histological features of chronically inflamed paratendineal tissue of the Achilles tendon are profound proliferation of loose, immature connective tissue and marked obliterative and degenerative alterations in the blood vessels. These changes cause continuing leakage of plasma proteins, which may have an important role in the pathophysiology of these injuries. The chronically inflamed paratendineal tissues of the Achilles tendon do not seem to have enough capacity to form mature connective tissue.

Abstract
Athletes often suffer from recurrent or chronic overuse symptoms of the lower extremities. During the office visit it is essential to analyse the patient's shoes, gait cycle, lower extremities and, especially, the talocrural, subtalar and more distal joints of the ankle and foot. The basic (clinical) biomechanical analysis can be supplemented by radiographs, treadmill and video analysis and mirror table (podoscope) examinations. Ideally, successful pain relief by correction of the observed abnormality with an orthotic device completes the diagnostic procedure, especially if symptoms return soon after the removal of the device. In treatment custom-made, expensive orthotics should not be prescribed for overuse symptoms without an obvious malalignment, for asymptomatic athletes with a malalignment, or for symptoms in which the causal relationship between the biomechanical abnormality and symptoms is difficult to see. Strict indications for prescription of orthotics and close cooperation between the attending physician, physical therapist and orthotist are prerequisites for obtaining good, long-lasting results.

Abstract
In the past 15 to 20 years gymnastics has become very popular. The increased participation exposes a greater number of athletes to potential injury. The risk of gymnastic injuries seems to be proportional to the level of the athletes; the higher the level of gymnastics, the more hours are spent in practice, with a greater exposure time. With the increased risk in gymnastics, the incidence of acute injuries will also increase, and as the skill level increases, the load during the workout will also increase, providing more opportunity for chronic injuries. As in many sports, the ankle is the most injured body part. Some injuries, however, seem to be specific to gymnastics. In gymnastics the upper extremities are used as weightbearing limbs, so high impact loads are distributed through the elbow and wrist joint. Back problems appear to result not only from single episodes of macrotrauma, but also from repeated microtrauma caused by specific impact loads during vaults and hyperextension. Early detection is the key to treating elbow, wrist and back pain in the gymnast. Reinjury following an acute injury may be reduced by allowing for complete rehabilitation before returning to full practice. Some studies indicate that maturation rate could play a potential role in injury predisposition. The combination of periods of rapid growth and intense training could provide for conditions where the gymnast is more injury prone.

Abstract
This study investigated the relationship between exposure time and ankle sprains in soccer. Forty-one teams (639 players) from four male senior soccer divisions at different levels of skill (divisions I-VI) were followed prospectively for 1 year. The exposure to soccer and the number of injuries per player were higher in higher divisions, but the injury incidence, percentage of ankle injuries and incidence of ankle injuries were the same at different levels of skill. Of all injuries 17 to 20% were ankle sprains and the incidence varied between 1.7 to 2.0 ankle injuries per 1,000 hours of exposure. Since players with previous ankle problems run an increased risk of reinjury we suggest that these players receive preventive advice.

Abstract
A 30-month prospective follow-up study of children's overuse injuries at an outpatient sports clinic was carried out to determine the number, profile, and specific features of these injuries compared with those of young adults. During this period 74 athletically active boys (less than or equal to 15 years), 83 girls, 255 men (21-30 years), and 77 women visited the station because of an overuse sports injury of the musculoskeletal system. About one-third of the patients of each group did not seek medical help until more than 6 months after the onset of the symptoms. The injuries most commonly affected the lower extremities, with the knee joint involved in about one third of patients. In girls and women, the lower back (13%) was significantly more frequently affected than in boys and men (6%) (p less than 0.01). Thirty two percent of all boys' overuse problems were classified as exercise-induced growth disorders and osteochondritic pains (apophysitides, etc.), but in girls only 13% had a similar basis. The most common diagnosis among boys was Osgood-Schlatter's disease (13 patients, 18%); in girls it was nonspecific synovitis of the knee (9, 16%).

Abstract
From 240 questionnaires, we investigated the prevalence of stress fractures in competitive collegiate female long distance runners and its relationship to menstrual history. The runners were divided into three groups according to their menstrual history: very irregular 69/240 (0 to 5 menses/year), irregular 51/240 (6 to 9 menses/year), and regular 120/240 (10 to 13 menses/year). Stress fractures occurred in 49% of the very irregular runners, 39% of the irregular runners, and 29% of the regular runners. The majority of the stress fractures occurred in the tibia. Runners who had never used oral contraceptives were over twice as likely to have had a stress fracture when compared with runners who had used oral contraceptives for more than 1 year. These data suggest that female distance runners who have a history of irregular or absent menses and who have never used oral contraceptives may be at an increased risk for developing a stress fracture. When amenorrheal runners were separated from the very irregular group, an alarming trend was noted in eating behavior disorders. Forty-seven percent of the amenorrheal group, 20% of the one to five menses/year group, 10% of the irregular group, and 7% of the regular group admitted to an eating behavior disorder.
