Injuries to the Female Athlete in 2017

Contraception, female cycle disorders and injuries in Swiss female elite athletes-a cross sectional study

Aim: The national Olympic committee of Switzerland has conducted an online survey among female elite athletes with a focus on cycle disorders, contraception, and injuries in 2021. Methods: A total of 1,092 female elite athletes from 107 different sports were asked to answer the questionnaire. A descriptive analysis was carried out to determine location parameters and create frequency tables. Results: The questionnaire was completed by 408 athletes (37.4%) from 92 different sports. 43.4% participated in a lean sport. 57.1% reported no injuries, 32.6% one injury, and 10.2% two or more injuries per year. A considerable proportion reported being affected by primary amenorrhoea (10.8%). Primary amenorrhoea occurred significantly more often in female athletes with a BMI lower than 21.7 kg/m2 (15.2%) than in athletes with a BMI above 21.7 kg/m2 (7.4%, p = 0.021). Considering contraception, 25.8% of female athletes were currently using an oral contraceptive pill. The proportion of female athletes not using contraception at all or using non-hormonal contraceptive methods was high at 54.4%. In lean sports, significantly more athletes used no or non-hormonal contraceptives (p < 0.05). Conclusion: Among top Swiss female athletes, a considerable proportion used non-hormonal or no contraceptives. This trend was more evident in lean sports. Delayed menarche and cycle irregularities were common among female athletes, especially among athletes with high training volumes as well as a BMI below 21.7 kg/m2. This orienting survey underlines the importance of specialized gynecological care for elite female athletes.

What place does elite sport have for women? A scoping review of constraints

Introduction

Despite increases in participation and raised attention for girls and women in sports, female sport is still based on male evidence that ignores gendered differences and experiences of unequal treatment and marginalization from grassroots to elite sport. This paper aimed to critically interrogate the place that women have in the male preserve of elite sport by conducting a two-part study.

Methods

First, we provided a brief sociohistorical analysis of gender in sport as a means to move away from a decontextualized and universalized approach dominating in sport science literature. We then conducted a scoping review following PRISMA-ScR guidelines to synthesize existing sport science literature that implemented Newell's constraints-led approach to examine elite performance.

Results

Ten studies were identified, none of which collected demographic data or centred on female athletes and the effects of sociocultural constraints on their performance. Instead, male-centred, masculine sports and physiological profiles dominated the identified studies.

Discussion

We discussed these results considering critical sport research and cultural sport psychology literature to offer an integrative, interdisciplinary approach to advocate for more culturally sensitive, context-specific interpretations of gender as a sociocultural constraint. We put forth a call to action for sport science researchers, practitioners, and decision-makers to move away from implementing male evidence in female sport and attend to the unique needs of female athletes. Practical suggestions aimed to help stakeholders reimagine elite sport by celebrating these [potential] differences as strengths for promoting gender equity in sport.

Dance-Related Foot and Ankle Injuries and Pathologies

Dancers are highly vulnerable to injuries due to high dynamic overload, extreme positions and motions, and excessive use. Increased load at the forefoot with jumping and high-impact lands can cause sesamoiditis and stress fractures of the metatarsals. Significant plantarflexion can lead to posterior joint impingement and flexor hallucis longus tendonitis, whereas forced dorsiflexion can cause anterior joint impingement. Most pathologies can be diagnosed on physical examination and various imaging modalities. Treatment should be tailored to the dancers' needs and should begin with a course of conservative therapy with immobilization, physical therapy, and activity cessation.

Gender Differences May Exist in the Presentation, Mechanism of Injury and Outcomes Following Bone Marrow Stimulation for Osteochondral Lesions of the Talus

Bone marrow stimulation (BMS) is indicated for patients who have symptomatic osteochondral lesions of the talus (OLT). Despite differences in ankle biomechanics and cartilage morphology between men and women, there is scant evidence examining whether these differences affect surgical outcomes. The purpose of this study was to compare the outcomes in men and women following BMS for OLTs. A retrospective analysis comparing female and male patients treated with BMS for OLT between 2007 and 2015 was performed. Clinical outcomes were evaluated using the Foot and Ankle Outcome Scores (FAOS) and Short-Form 12 (SF-12). Magnetic resonance imaging at final follow-up was evaluated with the modified magnetic resonance observation of cartilage repair tissue score. Thirty-one females and 38 males were included. In female patients, the mean FAOS pain score improved from 60 ± 16 preoperatively to 84 ± 8.9 at 1- to 2-year follow-up (p < .01), and then decreased to 80±13 at final follow-up at 3-4 years. In male patients, the mean FAOS pain score improved from 65±17 preoperatively to 83±9.2 at 1-2 year follow-up (p < .01), and then decreased to 76±14.6 at final follow-up at 3-4 years. Lateral lesions were more common in male patients. Medial lesions were more common in female patients. The outcomes following BMS in both female and male patients were good with no significant differences at short-term follow-up. FAOS scores in male patients were more likely to decrease after 1 to 2 years postsurgery, implying a possibly faster decline than in female patients.

Sports-Related Shoulder Injuries Among Female Athletes

PURPOSE OF REVIEW

The objectives of this review are to explore the recent literature evaluating sports-related shoulder injuries among female athletes.

RECENT FINDINGS

Recent literature has highlighted sex-related differences in injury trends and patterns among athletes. Increased participation of women in both recreational and professional sports has resulted in increased exposure to injury. While men experience greater rates of shoulder injury overall, women tend to experience more overuse-related injuries. Evidence also suggests women are more susceptible to shoulder laxity and rotator cuff tears. In comparison to their male counterparts, women note poorer function, increased pain, and decreased activity level following shoulder injuries. Women may also be more likely to experience worse outcomes following surgical intervention. Sex-related differences in injury patterns and outcomes results from a combination of molecular and environmental influences, including hormone pathways, shoulder morphology, and differing rates of participation in, and athletic regulations among, certain sports. Sex-related differences occur in how athletes sustain, experience, and recover from sports-related injuries. A comprehensive understanding of sex-related injuries enhances clinical decision making, treatment, and recovery. Further research is needed to clarify sex as an independent variable when evaluating sports-related shoulder injuries.

Sports-Related Craniofacial Injuries Among Pediatric and Adolescent Females: A National Electronic Injury Surveillance System Database Study

BACKGROUND

Number of female athletes continues to exponentially increase in all sports; however, available literature detailing craniofacial injuries remains scarce. Compared to male athletes, female athletes may experience different types of injuries. These may be related to sex differences such as craniofacial pain and dimensions. Thus, this study assesses the type of sport and craniofacial injuries that pediatric and adolescent female athletes sustain.

METHODS

National Electronic Injury Surveillance System was analyzed for all hospital admissions for young female athletes (5-24 years old) experiencing a sports-related craniofacial injury. These included contusions and abrasions, lacerations, fractures, and hematomas. Following sports were analyzed for craniofacial injury: basketball, golf, soccer, ice skating, swimming, softball, horseback riding, volleyball, field hockey, and football.

RESULTS

Most of the sports-related craniofacial injury occurred in female athletes who are between 10 and 19 years old. Across all age groups, softball (34.9%), basketball (28.1%), and soccer (15.6%) caused majority of the craniofacial injuries. The most common presenting craniofacial injury types were contusions and abrasions as well as lacerations.

CONCLUSIONS

There is a need for improved protective gear, such as face shields and low-impact balls, especially in softball and basketball. Physicians should consider the differences in female versus male and child versus adult injury pattern when treating female athletes in order to prevent long-term complications, such as scarring and depression. Overall, sports-related craniofacial injuries among female athletes need to be further examined as the epidemiology of their injuries and their health needs are unique.

Sex-Specific Analysis at Two Time Points in Three High-Impact Orthopaedic Sports Medicine Journals

Purpose

To determine how well the orthopaedic sports medicine literature reported sex-specific analysis (SSA) in 2011 and 2016.

Methods

The 3 highest-impact orthopaedic sports medicine subspecialty journals (American Journal of Sports Medicine; Arthroscopy; and Knee Surgery, Sports Traumatology, Arthroscopy) were selected for review. Two independent investigators reviewed all journal issues published during 2 different calendar years (2011 and 2016). All randomized controlled, prospective and retrospective group, and case-control studies were included. Studies were stratified into those that involved SSA, where sex was a variable in a multifactorial statistical model, and those that only reported sex as a demographic characteristic or used sex-matched groups without further analysis.

Results

A total of 960 studies evaluating 3,400,569 patients met criteria and were included in this review. Although 44.4% of the overall study population was female, only 293 (30.5%) studies included patient sex as variable in a multifactorial statistical model. The proportion of studies that performed SSA did not differ between 2011 (29.6%) and 2016 (31.1%; P = .607), although publications from American Journal of Sports Medicine were likely to report SSA (P < .05). Of the 293 studies that reported SSA, 91 (31%) demonstrated a significant difference in outcomes. The most commonly reported differences were in outcomes following anterior cruciate ligament, medial patellofemoral ligament, and posterior cruciate ligament reconstruction; autograft preparation; postoperative use of opiates following arthroscopy; and recovery after sports-related concussions.

Conclusions

Although most sports medicine studies include approximately 50% female and 50% male patients, statistical analysis differentiating the 2 subsets is not routinely performed. Only 30.5% of all studies performed SSA, 31% of which reported a statistically significant difference in the data when comparing outcomes between male and female patients with the same treatment modalities.

Clinical Relevance

The current study demonstrates that the orthopaedic sports medicine subspecialty literature is lacking in reporting SSA, and that there has been minimal improvement over a 5-year time period. In addition, this study highlights the high percentage of significant findings within the studies that performed SSA and underscores the differences in sex-specific injury patterns and treatment outcomes.

Foot and Ankle Related Sex-Specific Analysis Within High-Impact Journals

BACKGROUND

The impact of patient sex on the prevalence of foot and ankle injuries has been established. Reporting of differences on treatment outcomes is lacking. The purpose of this study was to identify trends in sex-specific outcomes across high-impact journals over a 5-year time period.

METHODS

Two independent investigators reviewed journal issues published during 2 calendar years (2011 and 2016) in the 5 highest-impact orthopedic foot and ankle/sports subspecialty journals (Foot & Ankle International [FAI], Foot and Ankle Surgery [FAS], American Journal of Sports Medicine [AJSM], Arthroscopy, and Knee Surgery, Sports Traumatology, Arthroscopy [KSSTA]). Studies were stratified into those that involved sex-specific analysis (SSA), where sex was a variable in a multifactorial statistical model, and those that only reported sex as a demographic characteristic or utilized sex-matched cohorts.

RESULTS

A total of 473 studies evaluating a total of 273 128 patients met criteria. An average of 43.9% (119 967 patients) of the population were female. Only 16.7% (79/473) of studies included sex as variable in a statistical model. Thirteen percent (25/193) and 19.3% (54/280) of studies reported SSA in 2011 and 2016, respectively. FAI was the only journal demonstrating a significant improvement of reporting SSA from 2011 to 2016 (P < .002). Thirty percent (24/79) of studies that performed SSA demonstrated significant differences between male and female outcomes.

CONCLUSION

Reporting of SSA in the orthopedic literature continued to be lacking. Only 16.7% of all articles evaluated in 2011 and 2016 performed SSA, with 30% of this subset reporting a statistically significant difference in outcomes.

LEVEL OF EVIDENCE

Level III, comparative study.

Part II: presentation, diagnosis, classification, treatment, and prevention of stress fractures in female athletes

Objectives: Stress fractures (SFx) occur as the result of repetitive loads over short periods of time, which leads to micro-damage of the bone through cortical resorption, ultimately leading to fracture. They are a common injury in female athletes and often cause significant morbidity. The goal of this study is to review the presentation, diagnosis, classification, treatment, and prevention of SFx in female athletes.Results: A thorough history, physical exam, and appropriate imaging can facilitate early diagnosis of stress fracture (SFx) and faster resolution of symptoms with more conservative management. The female athlete triad is an especially important factor that contributes to the increased risk of SFx in females. The continuum of stress injuries ranges from mild microfailure to complete fracture, which has resulted in the development of newer grading schemas through MRI and radiographic findings. Stress fractures are also classified as low- or high-risk according to anatomic location, as blood supply and applied forces at different locations affect the likelihood of fracture propagation, displacement, delayed union, or non-union.Conclusions: The ability to screen for at-risk athletes is paramount in preventing SFx. Recognition and prompt treatment of the female athlete triad requires a multidisciplinary approach in order to restore energy balance, correct menstrual irregularities, and improve bone health. This review provides a basis for understanding how to identify and treat stress fractures, which may allow treating physicians to diagnose this condition earlier and minimize any associated morbidity.

Epidemiology of Clavicle Fractures Among US High School Athletes, 2008-2009 Through 2016-2017

Background

Little is known about the epidemiology of clavicle fractures in United States (US) high school athletes. Sports participation among high school students has increased steadily, placing increased numbers at risk of sports-related injury.

Purpose

To describe the epidemiology of clavicle fractures among high school athletes, including injury rates by sex, sport, and type of play and trends in operative versus nonoperative treatment.

Study Design

Descriptive epidemiology study.

Methods

The study data set included all athlete-exposure (AE) and clavicle fracture data collected from 2008-2009 through 2016-2017 from a large sample of US high schools as part of the National High School Sports-Related Injury Surveillance Study for students participating in boys' football, boys'/girls' soccer, boys'/girls' basketball, boys'/girls' volleyball, boys' wrestling, boys' baseball, girls' softball, girls' field hockey, boys' ice hockey, boys'/girls' lacrosse, boys'/girls' swimming and diving, boys'/girls' track and field, girls' gymnastics, girls' cheerleading, boys'/girls' tennis, and boys'/girls' cross-country.

Results

Overall, 567 clavicle fractures were reported during 31,520,765 AEs, an injury rate of 1.80 per 100,000 AEs. Injury rates varied by sport, with the highest rates in the boys' full-contact sports of ice hockey (5.27), lacrosse (5.26), football (4.98), and wrestling (2.21). Among girls' sports, the highest rates were in soccer (0.92), lacrosse (0.26), and basketball (0.25). In sex-comparable sports, injury rates were still significantly higher among boys (1.03) than girls (0.35) (rate ratio, 2.91; 95% CI, 1.97-4.30). Injury rates were significantly higher in competition (4.58) as compared with practice (0.87) (rate ratio, 5.27; 95% CI, 4.44-6.26). Most injuries were treated conservatively (82.7%) rather than operatively (17.3%). Time to return to sports varied, with a greater proportion of medical disqualifications among those treated operatively (40.0%) as compared with those treated conservatively (22.6%) (injury proportion ratio, 1.77; 95% CI, 1.31-2.39).

Conclusion

Although clavicle fracture rates are relatively low, they vary by sport, sex, and activity. Understanding such differences should drive more effective, targeted injury prevention efforts. Increased time loss from sports with surgical versus conservative treatment may have been influenced by factors including injury severity and its timing relative to the season's progress.

Female athletes: managing risk and maximizing benefit

PURPOSE OF REVIEW

The purpose of this review is to provide an updated summary on the unique aspects of caring for female youth and adolescent athletes.

RECENT FINDINGS

Recent research on female athletes has led to a better understanding of injuries and conditions that are more likely to occur in female youth and adolescent athletes, including the frequency and severity of concussions, musculoskeletal injury such as involving the anterior cruciate ligament, and the female athlete triad. Social factors, such as the growing pressure to specialize in a sport particularly at an early age, also put young female athletes at risk for issues such as overuse injuries. Researchers continue to explore the benefits of athletic participation that extend beyond physical fitness.

SUMMARY

Female participation in youth sports has increased dramatically during the past 50 years. This has led to greater research on how to manage risks and maximize benefits for young female athletes, although there is still much to be learned. Providers should educate patients, parents, and coaches on both the increased risks for female athletes and ways to provide better support and accessibility of youth sports to all children.
