Extremity Injuries

Background: Artistic competitive gymnastics results in a wide, unique spectrum of injuries. Due to the high number of injuries and the current lack of research related to pre-competitive testing in adolescent gymnasts, it is crucial to find a method to predict the likelihood of an athlete sustaining an in-season injury. Purpose: The purpose of this study was to 1) describe the frequency and type of pre-season and in-season injuries, 2) determine if there were differences in physical performance tests between those who had a lower extremity (LE) injury in-season and those who did not, and 3) determine if there were differences in age, level, sex, BMI, sport modifications, previous injury, and current injury between those who had a LE injury and those who didn’t. Methods: Thirty-seven adolescent gymnasts (average age: 12.81 years) were included with levels ranging from 5 (novice) to 10 (elite). Participants (15 males and 22 females) were surveyed for previous and current injury. The athletes completed a performance battery before the competition season including: Lower Quarter Y-Balance Test (LQYBT), Closed Kinetic Chain dorsiflexion (CKCDF), single hop (SH), triple hop (TH), and the Functional Movement Screen (FMS). Follow-up data was collected at the end of the competitive season for comparison. The data was analyzed using descriptive methods and comparative analyses including chi-square and independent t-tests with an alpha level set at .05. Results: Sixty-five percent reported an injury in the last year and seventy-eight percent reported pre-season injuries at testing day. The most common location for pre-season injury was the ankle/foot (24% and 31% respectively). There were no differences between injured and non-injured athletes when comparing asymmetries in CKCDF, LQYBT posteromedial or posterolateral reach, hop testing, or FMS. The LQYBT-anterior scores were significantly different at p=.049 between the injured versus uninjured groups, with 91% of the in-season injury group having a difference <4cm. Similarly, the LQYBT-composite score using a cut-off of 95% was significant at p=.043 with those >95% category being more likely to get injured. There were no significant differences in demographic information comparing injury occurrence. Conclusion: The tested physical performance battery may be useful in tracking gymnasts over time, but may not be beneficial in forecasting injuries in a sport with high percentages of acute injuries. The collected injury volume may not be reflective of a standard season as COVID-19 decreased the number of competitions. Additional research to identify athletes at risk for injury requires further investigation.

Extremity Injuries

Background: Gymnastics exposes the body to many different types of stressors ranging from repetitive motion, high impact loading, extreme weight bearing, and hyperextension. These stressors predispose the spine and upper and lower extremities to injury. In fact, among female sports, gymnastics has the highest rate of injury each year. Purpose: The purpose of this study was to systematically review the literature on location and types of orthopedic injuries in adolescent (≤20 years) gymnasts. Methods: The Pubmed, Medline, EMBASE, EBSCO (CINAHL) and Web of Science databases were systematically searched according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines to identify all studies reporting orthopedic injuries in adolescent and young adult gymnasts. All aspects of injuries were extracted and analyzed including location, type and rates of orthopedic injuries. Results: Screening yielded 22 eligible studies with a total of 427,225 patients. Twenty of 22 studies reported upper extremity injuries of which four specifically focused on wrist injuries. Eight studies reported lower extremity injuries. Nine studies reported back/spinal injuries. Seven studies investigated each body location of injury; one study reported the upper extremity as the most common location for injury and six studies reported the lower extremity as the most common location for injury. Of those seven studies, five (23%) reported sprains and strains as the most common injury. One study reported fractures as the most common injury. Conclusion: There is considerable variation in reported injury location. Some studies focused specifically on the spine/back or wrist. The type of gymnastics each patient participated in was also different, contributing to which area of the body was more heavily stressed, or lacking. Current literature lacks data to fully provide evidence regarding which body region is more frequently injured and the type of injury sustained.

A Prospective Study

Background: Overuse injuries in sports seem to be 1.5 to 2.5 times more common than traumatic injuries in the lower extremity (LE) in children and adolescents. Floorball is the most popular indoor sport in Sweden and is associated with many potential risks of injuries. However, to our knowledge, no previous studies have examined the appearance of injury in young floorball players. Objective: The aim of the present study was to investigate the occurrence of overuse injuries in LE in floorball players aged 15 or younger, with respect to frequency, location, and consequence of injury. Method: Fifty-seven players, from 9 different teams, participated (mean age 11±2 years). A modified version of Oslo Sports Trauma Research Center Overuse Injury Questionnaire was submitted every fourth week during five months in order to record overuse injuries in LE. An online survey software was used to send out the questionnaires. Results: A of 42 overuse injuries in 42% (24/57) of the cohort were found. The average monthly prevalence for all players, in any anatomical area, was 28% (95% confidence total interval 18%-38%). The most common location of injuries was the knee (43%), followed by the foot (40%). Conclusion: The present study shows, in accordance with other recent studies on children and adolescents that overuse injuries seem to be a common problem for young floorball players. Knee and foot appear to be the most common location for overuse injuries in this population. Prospective analyses of different mechanisms for overuse injury in youth athletes and the relation to growth-related overuse disorders is desirable.

The Relationship

The purpose of this study is to demonstrate whether neurocognitive evaluation can confirm the association between neurocognitive level and postural control and to analyze the relationship between neurocognitive level and acute musculoskeletal injury in male non-net sports athletes. Seventy-seven male non-net sports athletes participated in this study. The Standardized Assessment of Concussion (SAC), Landing Error Scoring System (LESS), Balance Error Scoring System (BESS), and Star Excursion Balance Test (SEBT) were used for testing; we collected data related to injury history for six months after testing. Pearson’s correlation analysis, logistic regression, and the independent sample t-test were used for statistical analysis. The correlation between SAC and SEBT results was weak to moderate (p < 0.05). Eleven of the seventy-seven participants experienced acute lower limb injuries. SAC, LESS, BESS, and SEBT results have no effect on the occurrence of acute lower extremity injuries (p > 0.05) and were not statistically different between the injured and non-injured groups (p > 0.05). Therefore, using the SAC score alone to determine the risk factor of lower extremity injuries, except in the use of assessment after a concussion, should be cautioned against.

Extremity Injuries

AbstractLower extremity arterial injuries (LEAIs) can be complicated injuries resulting in limb loss and death. Patients with LEAI often have multiple injuries increasing the risk for morbidity and mortality. We sought to evaluate the incidence and management of LEAI and to define associations between injuries and outcomes. We performed a retrospective review of LEAI at an urban level-1 trauma center from April 2005 to April 2015. Chi-square tests were used to compare independent groups with respect to mortality and amputation. Means were compared between independent groups using two-sample t-tests. From April 2005 to April 2015, 208 arterial injuries occurred in 163 patients. The majority (80.4%) suffered concomitant lower extremity injuries with 35.6% suffering systemic injuries. Surgical intervention was required for 72.1% of injuries. Amputation rate was 14.7%. Mortality rate was 8.0%. Data from 2010 to 2015 were more specifically analyzed. Injury severity score (ISS) was higher with fatalities (37 ± 13.16 vs. 11.8 ± 8.51, p < 0.0001) and in patients requiring an amputation (25.4 ± 15.32 compared with 11.6 ± 9.05, p = 0.0015). Popliteal artery injury was most likely to require an amputation (odds ratio [OR] = 2.9, p = 0.04). Mortality was more likely when systemic injuries were present (OR = 18.1, p = 0.0005). The majority of patients with arterial injuries require surgical management, most often with open surgical techniques. Arterial injuries associated with systemic injuries, blunt injury mechanisms, and higher ISS are at a significantly increased risk of mortality.

Reference:  Hegedus EJ, McDonough SM, Bleakley C, Baxter D, Cook CE. Clinician-friendly lower extremity physical performance tests in athletes: a systematic review of measurement properties and correlation with injury. Part 2: the tests for the hip, thigh, foot, and ankle including the Star Excursion Balance Test. Br J Sports Med. 2015;49(10):649–656. Clinical Question:  Do individual physical performance tests (PPTs) for the lower extremity have any relation to injury in athletes 12 years of age and older? Data Sources:  The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed to locate articles. Three databases were searched from inception to January 13, 2014: PubMed, CINAHL, and SPORTDiscus. Search phrases were sport, athletics, athletes, and injuries combined with strength, power, endurance, agility, and function. Reference lists of all remaining articles and personal collections of the authors were then reviewed for any missing articles. Study Selection:  Studies were included according to the following criteria: (1) published in English, (2) presented as complete articles (ie, no abstracts or posters), and (3) involved human participants. Studies were excluded on the following criteria: (1) a combination of PPTs was examined, (2) the results were measured using equipment that was expensive or not readily available to the average clinician, (3) the PPTs examined impairment-level data, (4) the PPTs examined tasks not relevant to the lower extremity, or (5) the participants scored 4 or less on the Tegner Activity Scale. The final analysis involved 31 studies. Data Extraction:  The name of the PPT and methods were extracted. Each PPT was then critiqued using the Consensus-Based Standards for the Selection of Health Measurement Instruments, a 4-point Likert scale. Data were also summarized using a score of unknown, strong, moderate, limited, or conflicting for the best evidence synthesis. Main Results:  A total of 14 PPTs were examined; however, names and methods of the PPTs were inconsistent throughout the literature. In descending order, based on frequency of appearance in the literature, the PPTs were (1) 1-legged hop for distance, (2) vertical jump, (3) Star Excursion Balance Test, (4) shuttle run, (5) 6-m timed hop, (6) triple hop, (7) 40-yd sprint, (8) triple crossover hop for distance, (9) 6-m timed crossover hop, (10) T-agility, (11) hexagon hop, (12) medial hop, (13) lateral hop, and (14) multi-stage fitness (beep test). The Star Excursion Balance Test in the anterior, posteromedial, and posterolateral directions was the only test that could help identify injury risk. The 1-legged hop for distance and hexagon hop showed a moderate ability to differentiate between normal and unstable ankles. In dancers, the medial hop in dancers differentiated between painful and normal hips with moderate evidence. Conclusions:  Very little evidence supports the use of PPTs for athletes with lower extremity injuries. A panel of experts needs to standardize the names and methods of widely accepted tests.

Background: Impaired neuromuscular function after concussion has recently been linked to increased risk of lower extremity injuries in athletes. Purpose: To determine if National Football League (NFL) athletes have an increased risk of sustaining an acute, noncontact lower extremity injury in the 90-day period after return to play (RTP) and whether on-field performance differs pre- and postconcussion. Study Design: Cohort study, Level of evidence, 3. Methods: NFL concussions in offensive players from the 2012-2013 to the 2016-2017 seasons were studied. Age, position, injury location/type, RTP, and athlete factors were noted. A 90-day RTP postconcussive period was analyzed for lower extremity injuries. Concussion and injury data were obtained from publicly available sources. Nonconcussed, offensive skill position NFL athletes from the same period were used as a control cohort, with the 2014 season as the reference season. Power rating performance metrics were calculated for ±1, ±2, and ±3 seasons pre- and postconcussion. Conditional logistic regression was used to determine associations between concussion and lower extremity injury as well as the relationship of concussions to on-field performance. Results: In total, 116 concussions were recorded in 108 NFL athletes during the study period. There was no statistically significant difference in the incidence of an acute, noncontact lower extremity injury between concussed and control athletes (8.5% vs 12.8%; P = .143), which correlates with an odds ratio of 0.573 (95% CI, 0.270-1.217). Days (66.4 ± 81.9 days vs 45.1 ± 69.2 days; P = .423) and games missed (3.67 ± 3.0 vs 2.9 ± 2.7 games; P = .470) were similar in concussed athletes and control athletes after a lower extremity injury. No significant changes in power ratings were noted in concussed athletes in the acute period (±1 season to injury) when comparing pre- and postconcussion. Conclusion: Concussed, NFL offensive athletes did not demonstrate increased odds of acute, noncontact, lower extremity injury in a 90-day RTP period when compared with nonconcussed controls. Immediate on-field performance of skill position players did not appear to be affected by concussion.
