BACKGROUND Femoral neck stress fractures(FNSFs)are commonly found in long-distance running athletes.For FNSFs,early diagnosis and proper treatment are important.The objective of this study was to report FNSFs that occurred after excessive exercise using trampoline in middle-aged women.CASE SUMMARY The patient was a 43-year-old woman who exercised jumping on a trampoline for 6 wk for 1-3 h a day to diet.Exercise includes repeated flexion-extension of the hip joint.The patient was admitted to the hospital due to sudden bilateral groin pain that occurred suddenly during a trampoline exercise.Hip magnetic resonance imaging(MRI)revealed bilateral FNSFs.After 2 wk of follow-up with conservative treatment,the pain slightly decreased.However,it did not disappear completely.It was determined that it was difficult to control symptoms only by conservation treatment.Thus,closed reduction and internal fixation using a cannulated screw were performed for the more painful left hip joint.After operation,the pain was improved.Walking using crutches was possible.Followup MRI showed that the right femoral head signal was decreased compared to the left femoral head signal.Therefore,nonsteroidal anti-inflammatory drug and conservative treatment were provided.CONCLUSION In middle-aged people,excessive trampoline exercise can repeat hip flexion and extension for a short period of time,leading to FNSFs. 展开更多

Background: Trampoline use is one of the most common causes of recreational injury in children. In recent years, trampoline parks have grown in popularity and may be altering the spectrum of the trampoline-related injuries that occur. These parks create increased opportunity for injuries that appear uniquely different from accident patterns seen with home trampoline use. Recent work has suggested this may result in injuries occurring in greater frequency and with increased severity that may result in a greater need of hospital admission and procedural management by subspecialty services. Case Series Presentation: This case series presents three such examples occurring after the opening of a trampoline park in our local community: 1) A displaced forearm fracture requiring closed reduction and orthopedic follow-up;2) An ankle fracture necessitating operative reduction and fixation;and 3) A facial injury with tooth avulsion prompting oral surgery consultation and endodontic follow-up. Conclusions: These cases demonstrate the complexity and severity of injury that can occur from trampoline park participation and should serve to increase awareness among health care providers of these risks to provide appropriate parental counseling and advocate for preventative measures. 展开更多
