FREQUENCY OF PERIPHERAL NERVE INJURIES IN ATHLETES OF CERTAIN SPORTS CLUBS IN THE CITY OF ZADAR

Peripheral nerves in athletes are susceptible to injury due to an increase in physiological requirements in the training process to neurological structures and to the soft tissues that protect them. The training process is conditioned by the rank and level of competition and its implementation largely depends on the education of professional staff. Common mechanisms of injury are pressure, sprain, strain, ischemia, and sports injury. Seddon's original system of dividing nerve injuries based on neurophysiological changes is most widely used in medicine. The initial stage of nerve injury is neuropraxia, the second stage is axonal degeneration, and the third stage is nerve cutting. Peripheral nerve injuries are more common in the upper extremities than in the lower extremities. They have specifics related to a particular sport, in this case, football and basketball, and often have a biomechanical component in the making. Early detection allows an appropriate rehabilitation program to be initiated and biomechanics changed before the nerve injury becomes permanent. Recognizing nerve injury requires an understanding of peripheral neuroanatomy, knowledge of common nerve injury sites, and awareness of the types of peripheral nerve injuries that are common and specific to a particular sport. Rehabilitation programs in the field of kinesiology can be read through FMS protocols. Electrodiagnostic tests (electromyography), somatosensory evoked potentials, magnetic resonance imaging, and ultrasound are used to diagnose peripheral nerve injuries. Proximal peripheral nerve injuries have a slightly poorer prognosis in terms of neurological recovery in athletes. The survey determined the frequency of injuries in the subjects and that there is a misunderstanding among the athletes themselves, which is a peripheral nerve injury. The survey also found that peripheral nerve injuries occur due to acute injuries, while chronic injuries are excessive, resulting in damage to muscles and joints, and rarely as a result of inappropriate sports equipment. Athletes' knowledge of what constitutes a peripheral nerve injury itself and how this type of injury should be given more importance in further general prevention has also been established.

Delayed peroneal muscle reaction time in male amateur footballers during a simulated prolonged football protocol

ABSTRACT Peroneal muscle fatigue could result in ankle inversion sprain injuries. This study investigated the peroneal muscle reaction time during a simulated prolonged football protocol. Nine male footballers completed a 105-minute simulated prolonged football protocol. The peroneal muscle reaction time to an ankle inversion perturbation was measured every 15 minutes by a surface electromyography system sampling at 1000 Hz. One-way repeated ANOVA with post-hoc paired t-test showed a steady upward trend starting from 48.9 ms at baseline to 57.1 ms at the end of the first half, followed by a recovery back to 50.9 ms at the start of the second half and a further delay in the last 30 minutes to 60.2 ms at the end of the protocol. Delayed peroneal muscle reaction was found after 30 minutes of the first half and 15 minutes of the second half of a football match. The risk of ankle sprain could increase in the latter minutes in each half protocol. Thus, prevention injury training strategies should focus on these specific durations in football matches.

Most injuries occurred in the lower limb (87.3%), with the knee (26.5%), ankle (21.6%), and foot (16.7%) reported as the most frequently injured body areas. Muscle/tendon accounted for 44.1% of tissue type injuries. Tendinopathy (27.5%), joint sprain (19.6%), and muscle injury (15.7%) were the most common pathology types reported. The mean injury severity score was 31.6. ConclusionsOne in 4 trail runners reported at least one RRI in the 12 months leading up to a race. RRIs mostly affected the lower limb specifically the knee, ankle and foot. Future research should establish injury risk factors to ultimately develop specific injury prevention strategies.

THE RELATIONSHIP BETWEEN GENDER, HISTORY OF ANKLE SPRAIN, AND ANKLE STABILITY WITH ANKLE SPRAIN STATUS

Injuries can occur as a result of various activities, which of them is a sport. In 2017, basketball was a sport that produced the highest prevalence of injury incidence in the United States at 15.77%. Athletes who have ankle sprain are 20-40% more likely to experience chronic ankle instability. This study analyzed the relationship between gender, history of ankle sprain, and ankle stability with ankle sprain status in basketball athletes of Universitas Airlangga Surabaya. This study was analytical-observational research using a cross-sectional design. The research population was basketball athletes who were members of the basketball club of Universitas Airlangga, and finally there were 23 respondents selected as the research samples. The sample selection used the accidental sampling technique. The results of chi-square test (α = 0.05) indicate that there was a relationship between the previous history of ankle sprain (p = 0.002; RR = 9.1) and ankle stability with ankle sprain status (p = 0.013; RR = 6.), but gender had no relationship with ankle sprain status (p = 0.435; RR = 1.6). It concludes that the history of ankle sprain injury and ankle stability were related to ankle sprain status, but gender was not related to it. Keywords: gender, history of ankle sprain, ankle stability, ankle sprain

When there is an ankle sprain injury the athlete has decreased functional ability and decreased instability of the ankle joint. One of the actions used to reduce the risk of injury and increase the performance of athletes is by providing a Neuromuscular Training Program (NMT). This study to prove the effect of the provision of the Neuromuscular Training Program on the functional performance. This study used a Randomized Pre Test and Post Test Group Design study design. Respondents of this study were male soccer athletes, amounting to 18 athletes who met the inclusion criteria, then divided into 2 groups randomly, each group consisted of 9 respondents. The study showed that there were differences in improvement in functional performance after the administration of the Neuromuscular Training Program in male soccer athletes with a history of ankle sprain. In the treatment group shows the results of functional performance (SLHT) with a value of p = 0,000 indicates a significant effect. Then the results of subjective functional performance measurements using Cumberland Ankle and Instability Tools (CAIT) in the treatment group showed the results of functional performance (CAIT) with a value of p = 0.005. From the results of the study that there were differences and improves in functional performance after the administration of the Neuromuscular Training Program in male soccer athletes with a history of ankle sprain.

The coordination patterns of the foot segments in relation to lateral ankle sprain injury mechanism during unanticipated changes of direction

Preventing lateral ankle sprain injuries (LAS) in females competing in court sports is a high priority, as an athlete’s risk for re-injury and developing long term dysfunction increases significantly after sustaining an acute LAS. Stability to the ankle joint is passively provided by the joint congruity and ligaments, and actively by the muscles acting on the foot. The ankle joint is most stable when loaded and dorsiflexed. However, during unanticipated changes of direction, typical in court sports, the foot is often in a vulnerable unloaded, plantarflexed position. Stability of the forefoot and controlling rearfoot movement to avoid excessive ankle inversion and adduction thus becomes imperative. Information regarding the coupling relationship between the forefoot (hallux and metatarsal segments) and the rearfoot (calcaneus segment) during unanticipated changes of direction is lacking. The aim of this study was to supplement current LAS prophylactic knowledge by describing and quantifying hallux-calcaneus and metatarsal-calcaneus coupling. The coupling angles between sagittal plane hallux, tri-planar metatarsal and frontal- and transverse plane calcaneus movement, respectively, were calculated with a modified vector coding technique which used segmental velocities in a local, anatomical reference frame instead of segmental angles in a global reference frame. Coupling relationships revealed anti-phase movement between sagittal- metatarsal and frontal plane calcaneus movement throughout stance. During loading, sagittal- and frontal plane metatarsal acceleration/deceleration were coupled with frontal-transverse plane calcaneus acceleration/deceleration respectively. The remainder of the braking phase was characterized by calcaneus eversion deceleration. During propulsion, the hallux and metatarsal segments increased plantar flexion velocity in response to calcaneus inversion and adduction acceleration. As the forefoot was the only point of contact during stance, the coupling between segments were most likely neuromuscular. Strengthening intrinsic and extrinsic foot muscles may thus contribute to foot and ankle stability, adding to current prophylactic LAS strategies.

Pathoanatomy and Injury Mechanism of Typical Maisonneuve Fracture.

ObjectiveMaisonneuve fracture is a special type of injury which are rare in clinic. The manifestation of such fractures is variable. The aim of this study is to describe the pathoanatomical features of typical Maisonneuve fracture on the basis of radiographs, computed tomography (CT) scans, magnetic resonance imaging (MRI), and intraoperative exploration findings, and to investigate the injury mechanism of this variety.MethodsThe data of 41 patients with Maisonneuve fracture from April 2014 to September 2019 were retrospectively analyzed. There were 32 males and nine females, the average age was 37.9 years (range, 18 to 61 years), the fractures occurred on the left side in 20 patients and on the right side in 21 patients. The cause of injuries were traffic accident in five patients, sprain injury in 20 patients, and falling injury from height in 16 patients. All patients underwent posteroanterior and lateral X‐ray examinations of the ankle and calf. CT scan of the ankle was performed in 38 patients, including three‐dimensional reconstruction in 33 patients. MRI examination of the ankle and calf was performed in 28 and five patients, respectively. Forty patients were treated with open reduction and internal fixation. The features of proximal fibular fracture, injuries of the medial and posterior structures of the ankle, injuries of the anterior inferior tibiofibular ligament and the interosseous membrane were recorded and analyzed.ResultsForty‐one patients had proximal one‐third fractures of the fibula including six patients with fracture involving the fibular neck, 30 with proximal one‐third fractures of the fibular shaft, and five with proximal–medial one‐third junction fracture of the fibular shaft. Thirty‐five patients (35/41, 85.37%) with injury of posterior structures, 34 patients had posterior malleolar fracture (34/41, 82.93%), and one patient had posterior inferior tibiofibular ligament rupture (1/41, 2.44%). There were 20 patients with type I fracture, four patients with type II fracture, and 10 patients with type III fracture according to the Haraguchi classification of posterior malleolus fracture. The fracture of the medial malleolus was in 30 patients (30/41, 73.17%), rupture of the deltoid ligament was in 10 patients (10/41, 24.39%), and medial structures intact were in one patient (1/41, 2.44%). All 41 patients had injury of the anterior inferior tibiofibular ligament.ConclusionsMaisonneuve fracture is characterized by fractures of the proximal fibula and the complete rupture of the anterior inferior tibiofibular ligament. Pronation–external rotation is the main injury mechanism. The manifestations of typical Maisonneuve fracture including that the fibular fracture located in proximal one‐third diaphysis and the fracture line was from anterosuperior to posteroinferior.

Using a Single Uniaxial Gyroscope to Detect Lateral Ankle Sprain Hazard

Lateral ankle sprain is very common in sports. Recently, there was a wearable assistive technology that stimulates the peroneal muscles to prevent this injury, but it requires a monitoring system to detect injury hazards and actuate the protection. This study presents the feasibility of a uniaxial gyroscope to monitor the peak ankle inversion velocity during common sporting motion and simulated ankle sprain motion. Ten males performed walking, running, 45-deg cutting, vertical jump-landing, stepping-down from a block, 5 kinds of simulated ankle sprain motion on sprain simulators, and a manual ankle-twisting motion in a biomechanics laboratory. The peak ankle inversion velocity was collected by an optical motion analysis system at 120 Hz. Besides, a uniaxial gyroscope was attached to the heel to collect the peak twisting velocity at 500 Hz. Pearson test showed a strong or high positive correlation between the two parameters. Independent t-test showed no difference between the two parameters in all testing motions except the manual ankle-twisting test which the value was 82% of that from the optical motion capture system and both values are above the threshold, 300 deg/s. We concluded the method is applicable to detect the hazard of lateral ankle sprain injury.

Delayed ankle muscle reaction time in female amateur footballers after the first 15\u2009min of a simulated prolonged football protocol

PurposeAnkle sprain injury rate is reported to be higher towards the end of a football match. Muscle fatigue may contribute to the delayed muscle reaction and subsequent injury. This study investigated the ankle muscle reaction time during a simulated, prolonged football protocol.MethodsSeven amateur female football players participated in a 105-min simulated, prolonged football protocol. An ankle muscle reaction test was conducted with a pair of ankle sprain simulators at a scheduled interval every 15-min. The reaction times of peroneus longus, tibialis anterior, and lateral gastrocnemius were collected using an electromyography system sampling at 1000 Hz. Repeated measures one-way multivariate analysis of variance with post-hoc paired t-tests were conducted to evaluate if the reaction time at each time point significantly differed from baseline. Statistical significance was set at p < 0.05 level.ResultsReaction times started from 40.5–47.7 ms at baseline and increased to 48.6–55.7 ms at the end. Reaction times significantly increased in all muscles after the first 15 min except for the dominant lateral gastrocnemius. Increased reaction times were seen in the non-dominant limb after 60 min for tibialis anterior, after 75 min for peroneus longus, and after 90 min for the lateral gastrocnemius.ConclusionsDelayed reaction time of the ankle muscles were found after the first 15 min and in the final 45 min of a simulated prolonged football protocol. Strategies for injury prevention should also focus on tackling the delayed ankle muscle reaction time in the acute phase (the first 15 min), in addition to the latter minutes in the second half.Level of evidenceControlled laboratory study, Level V.

Regeneration of grade 3 ankle sprain, using the recombinant human amelogenin protein (rHAM+ ) in a rat model.

Lateral ligament tears, also known as high-grade ankle sprains, are common, debilitating, and usually heal slowly. Ten to thirty percent of patients continue to suffer from chronic pain and ankle instability even after 3 to 9 months. Previously, we showed that the recombinant human amelogenin (rHAM+ ) induced regeneration of fully transected rat medial collateral ligament, a common proof-of-concept model. Our aim was to evaluate whether rHAM+ can regenerate torn ankle calcaneofibular ligament (CFL), an important component of the lateral ankle stabilizers. Right CFLs of Sabra rats were transected and treated with 0, 0.5, or 1 µg/µL rHAM+ dissolved in propylene glycol alginate (PGA). Results were compared with the normal group, without surgery. Healing was evaluated 12 weeks after treatment by mechanical testing (ratio between the right and left, untransected ligaments of the same rat), and histology including immunohistochemical staining of collagen I and S100. The mechanical properties, structure, and composition of transected ligaments treated with 0.5 μg/μL rHAM+ (experimental) were similar to untransected ligaments. PGA (control) treated ligaments were much weaker, lax, and unorganized compared with untransected ligaments. Treatment with 1 μg/μL rHAM+ was not as efficient as 0.5 μg/μL rHAM+ . Normal arrangement of collagen I fibers and of proprioceptive nerve endings, parallel to the direction of the force, was detected in ligaments treated with 0.5 μg/μL rHAM+ , and scattered arrangement, resembling scar tissue, in control ligaments. In conclusion, we showed that rHAM+ induced significant mechanical and structural regeneration of torn rat CFLs, which might be translated into treatment for grades 2 and 3 ankle sprain injuries.

Ankle Taping Effectiveness for the Decreasing Dorsiflexion Range of Motion in Elite Soccer and Basketball Players U18 in a Single Training Session: A Cross-Sectional Pilot Study

Ankle sprains have been defined as the most common injury in sports. The aim of the present study was to investigate the ankle taping for the reduction of ankle dorsiflexion range of motion (ROM) and inter-limb in elite soccer and basketball players U18 in a single training session. Methods: A cross-sectional pilot study was performed on 38 male healthy elite athletes divided into two groups: a soccer group and a basketball group. Ankle dorsiflexion ROM and inter-limb asymmetries in a weight-bearing lunge position were assessed in three points: with no-tape, before the practice and immediately after the practice. Results: For the soccer group, significant differences (p &lt; 0.05) were observed for the right ankle, but no differences for the asymmetry variable. The basketball group reported significant differences (p &lt; 0.05) for the right ankle and symmetry. Conclusions: Ankle taping decreased the ankle dorsiflexion ROM in youth elite soccer and basketball players U18. These results could be useful as a prophylactic approach for ankle sprain injury prevention. However, the ankle ROM restriction between individuals without taping and individuals immediately assessed when the tape was removed after the training was very low.

Magnetic resonance imaging of normal anatomy and injury of the peroneal tendon

Objective: To explore the MR characteristics of normal anatomy and injured peroneal tendon and the diagnostic value of MR in the peroneal tendon injuries. Methods: From February 2018 to December 2018, a total of 20 healthy volunteers (40 ankle joints) were selected, 10 males and 10 females, with an age range of 20-30 (26±3) years. Retrospective analyzed 62 patients with ankle sprain and peroneal tendon injuries confirmed by operation, 34 males and 28 females, with an age range of 14-78(41±14) years. All volunteers and patients underwent MR examination. The MRI characteristics of the normal anatomy of peroneal tendon were analyzed. The patients were classified according to the MR diagnostic criteria of injury. Then the MRI features of different types of injured peroneus longus tendon and peroneus brevis tendon were analyzed. At last, imaging findings were compared with surgical results. Results: The peroneal tendon of 20 healthy volunteers showed oval and elliptical band-like structures on T(1)WI and PD-FS sequences, with natural alignment, clear boundary and uniform low signal. The whole length of the peroneal tendon can't be displayed completely on the same imaging plane. It needed multi-dimensional observation combined with axial, coronal and sagittal directions. There were 62 cases of peroneal tendon injury, including 46 cases of peroneal tendon tear (7 cases of partial-thickness tear, 11.3% of the total injuries, 39 cases of full-thickness tear, 62.9% of the total injuries), 16 cases of peroneal tendon dislocation (15 cases of intrathecal dislocation, 24.2% of the total injuries, 1 case of extrathecal dislocation, 1.6% of the total injuries). In 7 cases of partial-thickness tear (4 cases of peroneus brevis tendon tear, 3 cases of peroneus longus tendon tear), MR showed irregular tendon shape and local continuity interruption. In 39 cases of full-thickness tear (31 cases of peroneus brevis tendon tear, 8 cases of peroneus longus tendon tear), MR showed that the tear was penetrated through the whole layer of tendon from dorsolateral side to plantar side of foot, and the range of tear was different. The torn tendon could be accompanied by tendinitis or effusion of tendon sheath; 15 cases of intrathecal dislocation (3 cases of type A, 12 cases of type B), MR findings of type A dislocation showed that the peroneus longus tendon was located in the deep part of the peroneus brevis tendon, MR findings of type B dislocation showed that the peroneus longus tendon was displaced into the longitudinal tear of peroneus brevis tendon. In 1 case of extrathecal dislocation (type Ⅲ), MR showed that the SPR and the attached cortex of lateral malleolus were avulsed together, and the peroneal tendon was displaced under the avulsed fracture piece. Conclusion: MR can accurately demonstrate the fine anatomical structure of peroneal tendon and the imaging features of injuries. It has important clinical application value for the early diagnosis and accurate treatment of peroneal tendon injuries.

Work-related injuries, postural stress, and musculoskeletal disorders among the railway track maintainers in India.

The main aim of this cross-sectional study was to evaluate work-related injuries (WRI) and the self-reported musculoskeletal symptoms among 742 railway track maintainers. The second aim of this study was to investigate the potential factors related to the prevalence of musculoskeletal disorders (MSDs) in track maintainers. This study also tried to do planning and implementing ergonomic intervention programs to improve track maintainer's health. Modified Nordic questionnaires were administered to assess the prevalence of MSDs. Detailed posture analysis by rapid entire body assessment (REBA) method was performed to assess the risk level of concerned postures. The injury data for 12 months were collected by conducting a survey and personal interviews with the affected railway track maintainers. To assess the prevalence of MSDs, the odds ratio and 95% confidence interval were computed along with critical χ 2 values. Analysis of variance was performed to determine significant differences between the MSD present and absent among the track maintainers of the Indian railway. The result of this study showed that neglect of safety precautions is the main reason for injury, followed by slipping and falling and lack of awareness. Sprain injury is one of the main injuries, followed by cut, snakebite, abrasion, and fracture. Low educational levels of workers are also reasons for WRI. In conclusion, the prevalence and severity of MSD, particularly in the low back, knees, wrist, and shoulder and WRI were found to be very high among the track maintainers. The recommendations of this research are ergonomic interventions, such as track maintainers proper training, following the National Institute of Occupational Safety and Health -recommended weight limit for manual material handling, modification in hand tools, job rotation, performing stretching exercise, and avoiding awkward and static posture are needed.

Fatigue increases ankle sprain risk in badminton players: A biomechanical study

ABSTRACT Ankle sprains are the most common injury in regular badminton players and usually occur at the end of a match or training. The purpose of the present study was to examine the influence of fatigue produced by badminton practice on the lower limb biomechanics of badminton players. It was hypothesized that fatigue induces ankle kinematic and lower leg muscle activity changes which may increase the risk of ankle sprain. Ankle kinematics, ankle kinetics and muscles activities of 17 regular badminton players were recorded during lateral jumps before and after an intense badminton practice session. Post-fatigue, ankle inversion at foot strike and peak ankle inversion increased (+2.6°, p = 0.003 and +2.5°, p = 0.005, respectively). EMG pre-activation within 100 ms before foot landing significantly decreased after fatigue for soleus (−23.4%, p = 0.031), gastrocnemius lateralis (−12.2%, p = 0.035), gastrocnemius medialis (−23.3%, p = 0.047) and peroneus brevis (−17.4%, p = 0.036). These results demonstrate impaired biomechanics of badminton players when fatigue increases, which may cause a greater risk of experiencing an ankle sprain injury.

Injury types and frequency in Spanish inline hockey players

ObjectiveTo describe injury types and frequencies in Spanish inline hockey players. DesignDescriptive epidemiological study. SettingAmateur inline hockey teams competing in Spanish leagues between 2010-2011 and 2016–2017 seasons. Participants154 inline hockey players (aged 10–42 years). Main outcome measurementsInjury incidence, body segment injured, injury mechanism and severity, type of injury, type of play at the time of injury, time of the season at time of injury, location on the rink at the time of injury, player position and use of protective equipment. Results80 injuries were reported. More than twice as many injuries occurred during games (67.5%) as practice (32.5%). The most common body site injured was the ankle (20%). Fractures (28.7%), and sprains (26.3%) were the most common type of injury. Non-contact skating (23.7%), falls (18.7%), and player contact (18.7%) were the most common mechanism of injury. Ankle sprain (10%) was the most common body site-type injury. Severe injuries (≥29 days’ time lost) occurred more often than mild to moderate injuries (<29 days’ time lost). ConclusionsThe risk of severe injury for inline hockey players is high. Non-contact injuries such as skating and falls had a high incidence. The characteristics of inline skating surface, mechanics of inline skating and fatigue may be the cause of a significant amount of the lower extremity sprain injuries. Continued surveillance is warranted to evaluate inline hockey injury trends over time.

Effectivenes of Hipermobility on Sport Injury among Young Players

The aim of this study is to investigate the relationship between hypermobility and sport injury in different sports branches. A total of 256 athletes who were 15,7±7,6 years average age from 5 different branches (football: 52 basketball: 28 volleyball: 32 swimming: 28 and athletics: 19) participated in the study voluntarily. Beighton hypermobility diagnostic scoring and sport injury history questionnaire were used to data collection. Study showed that; 19.5% of the participants were found to be advanced hypermobile. The highest rate of hypermobile was found in Volleyball branch (n: 12/37.5%). The incidence of hypermobility syndrome in women was found to be higher than in men (42.3%). 58.9% of the athletes had previously had a injury, the type of sprain injury was the most common type of injury (37.7%), the foot and ankle was the most injured body part (48.1%). Injury mostly occurs in training (45.3%). Overuse was the most injury reason (35.2%). Duration of the recovery was 1-3 weeks mostly answered (30.9%). Injury mostly seen in football branches (60.9%). No relationship was found between the injury status of the athletes and hypermobility levels (p= 0.103). As a result of the research; hypermobility prevalence was 19.5% found among participants. According to gender, analysis showed that; It was seen more frequently in women and the rate of hypermobility in volleyball branch was higher than other branches. On the other hand, it was found that the level of hypermobility had no effect on the sport injury history of the young athletes.

The influence of athletic taping and bracing on ankle sprain: A literature review

Ankle sprain is a common injury in sports, and it is considered one of the most body parts injured in athletes. An inversion ankle sprain is the most common type of ankle sprains injuries and constitutes 45% of sports injuries with a high recurrence level that could approximately affect 73% of athletes. This literature review is aimed to highlight the influence of the athletic taping and bracing on the athletic ankle sprains. Literature search was carried out using PubMed, SIMMON, Cochrane Library, and Google Scholar. Athletic taping and bracing have been used for athletes with the purpose of injury prevention and as treatment during sporting activities. However, some studies showed ankle sprain injury reduction significantly up to half of the injury rate while using athletic tape. Furthermore, wearing the brace significantly lowers the injury rate of 1.6 sprains/1000 exposure comparing to 5.2 sprains/1000 exposure to those who did not wear the brace. Finally, athletic taping and bracing are common modalities used in practice. There is a lot of confounding factors and doubt in the literature regarding the influence of these modalities on the incidence and severity of injurers.

The Association Between History of an Ankle Sprain and Traumatic Meniscal Injury Among Infantry Combat Soldiers in the Israeli Defense Forces: A Historical Cohort Study.

The high frequency and number of ankle inversion injuries and meniscal injuries in military populations is an area of concern due to the debilitating effects and cumulative consequences of these particular injuries on the soldiers sustaining injury and the consequences on the operational effectiveness of the Israeli Defense Force (IDF). This study examines the possible relationship between ankle inversion injury and potential for subsequent meniscal injury in infantry soldiers in the IDF. All 89,069 infantry combat soldiers (including special units), recruited to the IDF between 2007 and 2017 were included in this study. A historical cohort study was conducted. The cohort was divided into two groups: The exposure group included all participants that had suffered at least one ankle sprain in the past and the unexposed group that included all participants who did not suffer an ankle sprain in the past. A Cox proportional-hazards model (COX) model was used in order to obtain the adjusted to confounders association between exposure and outcome expressed in hazard ratio (HR). The crude association between ankle sprain in the past and the development of meniscal injury in this study was 0.87 (Relative risk=0.87, P=0.007). After adjusting for unit type, Body Mass Index (BMI), previous fracture of the lower limb, and the use of eyeglasses, using a COX model, the adjusted association between ankle sprain in the past and the development of meniscal injury was 0.8 (HR=0.8, P=0.001, confidence interval (95%) 0.74, 0.88). The results of this study indicate ankle sprains to be a protective factor for meniscal injury. Our main conclusion from the results of this study is that the assumption that those with previous leg injuries are at a greater risk for further leg injuries is questionable and cannot be generalized. Hence, the association between different types of injuries should be investigated separately.
