“…Additionally, the lateral and anterior center-edge angles of dancers are significantly higher than those of nondancers. This supports the premise of dancers’ having a higher prevalence of pincer morphology and elevated lateral center-edge angles and lower alpha angles than single-sport athletes who are nondancers, 20 and it suggests a difference in radiological presentation and FAI types among sports.…”

Background: Femoroacetabular impingement (FAI) has been extensively investigated and is strongly associated with athletic participation. Purpose: To assess (1) the prevalence of cam-type FAI across various sports; (2) whether kinematic variation among sports influences hip morphology; and (3) whether performance level, duration, and frequency of participation or other factors influence hip morphology in a sporting population. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic search of Embase, PubMed, and the Cochrane Library was undertaken following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Prospective and retrospective case series, case reports, and review articles published after 1999 were screened, and those that met the inclusion criteria decided a priori were included for analysis. Results: The literature search identified 58 relevant articles involving 5683 participants. A total of 49 articles described a higher prevalence of FAI across various “hip-heavy” sports, including soccer, basketball, baseball, ice hockey, skiing, golf, and ballet. In studies including nonathlete controls, a greater prevalence of FAI was reported in 66.7% of studies (n = 8/12). The highest alpha angle was identified at the 1-o’clock position (n = 9/9) in football, skiing, golf, ice hockey, and basketball. The maximum alpha angle was located in a more lateral position in goalkeepers versus positional players in ice hockey (1 vs 1:45 o’clock). A positive correlation was also identified between the alpha angle and both age and activity level (n = 5/8 and n = 2/3, respectively) and between prevalence of FAI and both age and activity level (n = 2/2 and n = 4/5). Conclusion: Hip-heavy sports show an increased prevalence of FAI, with specific sporting activities influencing hip morphology. There is some evidence to suggest that a longer duration and higher level of training also result in an increased prevalence of FAI. Registration: CRD4202018001 (PROSPERO).

“…Dancers more commonly have pincer morphology than cam morphology, with the alpha angle being significantly lower in dancers than nondancers 20 (see Table 3 ). Kolo et al 32 discovered the presence of cam morphology in only 1 of 30 dancers.…”

“…The fact that dancing was the third most common sports type performed by females, who underwent hip arthroscopy for FAIS, is another surprising finding. Although this result supports previous theories that supraphysiological hip, ROMs may cause impingement and excessive stress on intra‐articular structures, 27 earlier studies have reported a fairly low prevalence of cam morphology among dancers (3%‐18%) 27‐29 . This discrepancy between studies may indicate that those “few” dancers with cam morphology appear to run a higher risk of developing FAIS and potentially require treatment.…”

Horseback riding is common among female athletes who had arthroscopic treatment for femoroacetabular impingement syndrome

The purpose was to investigate pre‐operative symptoms and types of sport in competitive athletes undergoing arthroscopic treatment for femoroacetabular impingement syndrome (FAIS), and to compare between genders. Competitive athletes planned for arthroscopic treatment for FAIS were included prospectively in a hip arthroscopy registry. A total of 1548 athletes were identified and 919 were included. Sporting activity and patient‐reported outcome measures (PROMs), including HSAS, iHOT‐12, and HAGOS, were recorded, pre‐operatively. The study comprised 738 male and 181 female athletes (median age 25; interquartile range 20‐32 years) who had undergone arthroscopic treatment for FAIS. The most common sports type performed by males were football (48%) and ice hockey (19%) and in females, football (25%) and horseback riding (22%). Females reported a significantly longer duration of symptoms (median 36 vs 24 months) and lower pre‐operative scores for the iHOT‐12 and all the HAGOS subscales, except for physical activity. In conclusion, horseback riding and football are almost equally common in female athletes, while football is by far the most common in male athletes, who underwent arthroscopic treatment for FAIS. Females had a longer duration of symptoms and a higher degree of self‐reported symptoms and dysfunction prior to the hip arthroscopy.

“…From the 28 studies meeting inclusion/exclusion criteria, 1160 male athletes and 53 female athletes with radiographic cam deformity were identified ( Table 1 ). Soccer ¶ was the sport with the greatest reported number of affected male and female athletes, followed by hockey, 10 , 11 , 24 , 44 , 60 , 64 , 67 , 68 American football, 35 , 36 , 43 , 54 ballet/dance, 21 , 23 , 29 and track and field 37 , 40 ( Table 2 ). Male athletes were more commonly reported than females in all sports except for ballet/dance, track and field, and volleyball.…”

Background:Repetitive loading and shear stress across the proximal femur account for the high prevalence of cam deformity in athletes.Purpose:To systematically review the literature to identify the reported number, age, mean alpha angle measurements, and differences between male and female athletes with radiographic cam deformity based on sport.Study Design:Systematic review; Level of evidence, 4.Methods:A systematic review was conducted of studies in the literature between January 1990 and March 2018 that reported on athletes with radiographic cam deformity based on sport. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed, and PubMed, Biosis Previews, SPORTDiscus, PEDro, and EMBASE databases were used. Inclusion criteria included studies documenting radiographic cam deformity based on alpha angle measurements categorized according to the athlete’s primary sport and according to sex. Exclusion criteria were (1) studies not documenting primary sport, (2) studies not reporting total number of athletes with radiographic cam deformity, and (3) studies not separating cam deformity based on sex or using alpha angle measurements. Statistical analysis was used to compare mean reported age and alpha angle measurements between males and females.Results:A total of 28 studies consisting of 1160 male and 53 female athletes with radiographic cam deformity were identified. Cam lesions were most commonly reported in soccer athletes among both males and females, followed by hockey and American football. Male athletes had significantly higher mean alpha angle measurements (59.9° ± 5.5°) compared with female athletes (48.3° ± 6.9°) (P = .001). No significant difference in age was appreciated between males (21.1 ± 4.0 years) and females (21.7 ± 3.0 years) (P = .62).Conclusion:Radiographic cam deformity is most commonly reported in athletes participating in soccer and hockey. Males possessed significantly greater mean alpha angle measurements compared with females, whereas no significant difference in mean age at the time of diagnosis was appreciated between sexes.
