Abstract:Hip dislocations during sporting activities represent only 2%–5% of all hip dislocations. Most hip dislocations in sports can be categorised as “less complicated traumatic hip dislocations” by the Stewart-Milford classification due to the fact that minimal force is involved. The incidence of avascular necrosis of the femoral head greatly increases if the time to reduction is more than six hours. We report the case of a 38-year-old football player who suffered hip dislocation while kicking the ball with the med… Show more
“…Several contour lines seen at standard anteroposterior (AP) pelvic radiography aid in systematic interpretation (Fig 3) (18). Both the iliopectineal line (comprising the anterior column of the acetabulum) and the ilioischial line (comprising the posterior column) should be continuous and Hip dislocations in sporting activities are rare, representing only 2%-5% of hip dislocations, but may occur in high-velocity sports such as football and rugby (19)(20)(21). The position of the leg at the time of the trauma determines if the hip dislocates with or without fracture of the acetabulum or femoral head.…”

Hip dislocation is an important orthopedic emergency usually seen in young patients who have experienced high-energy trauma, often resulting in significant long-term morbidity. Rapid identification and reduction is critical, as prolonged dislocation increases the risk of developing avascular necrosis of the femoral head, and posttraumatic osteoarthritis is a common complication, even in the absence of associated fractures. Identification and timely management of hip dislocation are highly dependent on imaging, both at presentation and after attempted reduction. It is imperative for the radiologist to understand imaging features that guide management of hip dislocation to ensure timely identification, characterization, and communication of clinically relevant results. Although the importance of prompt identification of hip dislocation is universally recognized, the significance of imaging features that guide correct management and are thought to prevent complications is less emphasized in the radiology literature. In this article, the authors review the anatomy of the hip, common injury mechanisms for various types of dislocations, and imaging findings for associated injuries. They review the most commonly used classification systems and propose a simplified checklist approach to hip dislocation to aid rapid interpretation and communication of the most clinically relevant imaging features to the treating orthopedic surgeon.

“…Currently, falls from a height are the second most common cause of THDs whilst sporting injuries are a rarer cause, accounting for 2e5%. 6 THD is more common in younger patients, most frequent in men between 20 and 30 years of age. 7 The most common contemporary mechanism of injury associated with traumatic hip dislocations is road-traffic accidents.…”
“…Utilizing provided weighting, 2941 sports-related hip dislocations were estimated to have occurred over the 10-year period, representing approximately 295 injuries per year, which is higher than previously reported. 4 , 9 , 21 In 7 extreme sports, Sabesan et al 20 examined hip and knee dislocations using NEISS data from 2007 to 2012 and reported 35 hip dislocations with an estimated 742 hip dislocations during the 5-year period. While the aforementioned study is limited to hip dislocations in a select number of extreme sports, such as water skiing and wakeboarding, snowmobiling, surfing, roller skating, snowboarding, skateboarding, and snow skiing, our data represent estimates of the incidence rates for all sports-related hip dislocations in the United States.…”
Background: Traumatic hip dislocations are rare injuries that most commonly occur in motor vehicle accidents. There is a paucity of literature that describes sports-related hip dislocations. Purpose: To estimate the incidence of sports-related hip dislocations and determine any sport- or sex-related epidemiological trends using the National Electronic Injury Surveillance System (NEISS) database. Study Design: Descriptive epidemiology study. Methods: Data regarding sports-related hip dislocations from 2010 to 2019 were retrieved from the NEISS, a database that catalogs injury information during emergency department visits from 100 hospitals across the United States to produce nationwide estimates of the injury burden. The estimated number of injuries was calculated using weights assigned by the NEISS database. The injuries were then stratified by sport and sex to determine any epidemiological patterns. Results: A total of 102 hip dislocation injuries were identified over the surveyed 10 years, indicating 2941 estimated injuries nationwide. Overall, 10 (9.8%) of 102 sports-related hip dislocations presented with concomitant acetabular fractures, representing an estimated 288 injuries nationally over 10 years. Male athletes sustained more sports-related hip dislocations than female athletes, with a relative incidence of 12.51 ( P < .001). Adolescents aged 15 to 19 years recorded the highest number of hip dislocations. There were 17 sports identified as having caused at least 1 hip dislocation over the 10-year period. More hip dislocation injuries were sustained from contact sports (91.2%) than noncontact sports (8.8%) ( P < .001). Football (estimated 164 injuries per year; 55.6%), snowboarding (28 per year; 9.5%), skiing (26 per year; 8.8%), and basketball (21 per year; 7.1%) had the highest rates of hip dislocation. Additionally, 43 (82.7%) football-related injuries were caused by tackling mechanisms, and 9 (17.3%) were caused by nontackling mechanisms ( P < .001). Conclusion: The incidence of traumatic sports-related hip dislocations was extremely low in the United States during the study period. Male adolescents, aged 15 to 19 years, sustained the greatest number of injuries during football. Significantly more hip dislocations occurred in contact sports, most commonly football, snowboarding, skiing, and basketball, compared with noncontact sports. As adolescent athletes may have limited treatment options if osteonecrosis occurs, these data serve to increase the clinical awareness of these injuries.
