H istorically, skiing as a form of locomotion was instrumental in activities such as hunting, medical transportation, and military conflict. It was not until the early 1800's that skiing became popular as a means of exercise, and it would take nearly 100 years to be adapted as a sport. 34 Alpine ski racing became an Olympic sport in 1936, and the first International Ski Federation (FIS) World Cup race was held in 1967. 16 Alpine skiing is now well organized, with competitions ranging from junior through masters levels. Although recreational skiing injuries have been well described, there is less published work on injuries sustained during alpine ski racing. The forces, speeds, and slope conditions that ski racers encounter differ greatly from the average recreational skier. 14,53 The purpose of this article is to comprehensively review the existing literature with regard to alpine ski racing injuries and to identify further areas of study and potential strategies for injury prevention. Methods A review of the published literature from 1976 to 2018 pertaining to alpine ski racing injuries was performed. Pertinent articles were identified from PubMed, Ovid, and Google Scholar using the search terms "ski racing," "alpine ski racing," "injury," and "epidemiology." Additional studies, including studies regarding specific ski racing injuries, were identified from the references of relevant articles. Studies focused on snowboarding injuries or on recreational alpine skiing injuries were excluded. epideMiology Reported injury rates in alpine skiing are high. 2,9,11,15,28,36,51,56 At the World Cup level, which is the highest level of competition, the incidence of injury ranges from 23.5 to 36.7 injuries per 100 athletes per season. 15,19,28 Nearly half (45.0%) of injuries in World Cup athletes occur during competition 15,19 as opposed to 825842S PHXXX10.

Background There is limited evidence on the safety of return to sexual activity after hip arthroscopy. Aim To determine the positional safety of sexual activity after hip arthroscopy relative to hip instability and/or impingement risk. Study Design This study is an observational study. Methods 12 common sexual positions were identified based on previous research. Gender-specific hip motion was then assessed for the possibility of postarthroscopic hip instability (due to disruption of iliofemoral ligament [interportal capsulotomy] repair) and/or impingement (labral or capsular compressive stress with disrupted repair) for all 12 positions (both right and left hips; 15 unique male and 14 unique female positions). Instability risk was defined as greater than 0° hip extension, greater than 30° external rotation (ER), or greater than 30° abduction. Impingement risk was defined as greater than 90° hip flexion, greater than 10° internal rotation, and greater than 10° adduction. Outcomes A majority of both male and female sexual positions caused either instability or impingement, with only 4 positions in women and 4 positions in men deemed “safe” by avoiding excessive hip motion. Results Return to sexual activity after hip arthroscopy may cause instability in 10/15 of male positions and 5/14 female positions. Most male positions (6/10) were at risk for instability because of excessive ER. 2 positions were unstable because of a combination of ER and extension, one was due to extension, and one abduction. In female instability positions, all 5 were unstable because of excessive abduction. Impingement may be observed in 5 of 15 male positions and 6 of 14 female positions. In male impingement positions, all were due to excessive adduction. 4 female positions risked impingement due to excessive flexion and 2 positions due to internal rotation. Clinical Implications This study demonstrates risks that should be considered when counseling patients preoperatively and postoperatively regarding sexual activity. Strengths & Limitations This study closely models a hip preservation patient population by using 2 young and otherwise healthy individuals. The most significant limitation of this investigation was its basis with only 2 young healthy volunteers (one male, one female) in a single motion capture session using surface-based spherical retroreflective markers from a previous investigation. Conclusion After hip arthroscopy, patients need to be made aware of the possibility of hip instability (10 of 15 men; 5 of 14 women) and impingement (5 of 15 men; 6 of 14 women) due to excessive hip motion that may compromise their outcome.

Objective The aims of this study were to assess the psychological, functional, and physical differences between patients with femoroacetabular impingement (FAI) syndrome and individuals who were asymptomatic (controls) to analyze clinical differences among 4 subtypes of FAI (cam type, cam type with labral tear, pincer type, and pincer type with labral tear), to calculate the correlations among the variables described, and to identify risk factors contributing to the hip function variance. Methods A case–control study was conducted at a hospital rehabilitation unit with a cohort of individuals who were asymptomatic (controls) and a cohort of patients with FAI. Sociodemographic characteristics, pain intensity, psychological health status, hip range of motion (RoM), hip isometric strength, and hip function were assessed. Results A total of 69 controls and 69 patients with FAI were analyzed. Although sociodemographic characteristics were comparable between samples, poorer hip RoM, strength, and psychological health were found for the cases. FAI subtypes showed no significant pain intensity, psychological health, or RoM differences (except for hip adduction), but hip strength differed among FAI subtypes. Multiple significant correlations between psychological health, pain intensity, RoM, strength, and hip function were found. The variance values of the International Hip Outcome Tool, Hip Outcome Score for daily living activities, and Hip Outcome Score for sports activities were partially explained (47.6%, 36.0%, and 21.6%, respectively) on the basis of kinesiophobia, hip strength, self-efficacy, and anxiety. Conclusion Patients with FAI showed poorer psychological health, hip RoM, and strength than individuals who were asymptomatic and had similar sociodemographic characteristics. FAI subtype influenced the patients’ clinical presentations. Hip strength, kinesiophobia, anxiety, and self-efficacy should be targeted for improving hip function, as they have been demonstrated to be important contributors to hip disability. Impact This study demonstrated that pain catastrophizing, hip strength, and hip adduction differed among FAI subtypes. However, hip function and pain intensity were comparable between FAI subtypes.
