Introduction:
This study aims to analyze the characteristics of hip region stress fractures (HSFs) within a South Korean military cohort and identify the associated risk factors to provide insights for treatment and prevention strategies. Additionally, we will report the epidemiologic data and clinical outcomes of treating HSF within the second largest military hospital.
Materials And Methods:
Between January 2022 and December 2023, this retrospective case series revised all HSF patients' medical records to analyze demographic and epidemiologic data and clinical progress. The incidence rate was calculated using the number of conscripted soldiers based on publicly open available statistics from government institution.
Results:
A total of 95 hips from 60 patients were included in this study, and 35 patients (58.3%) exhibited bilaterality. The seasonal variation of HSF patients showed a bimodal distribution, with peaks from April to June and October to December. The incidence rate per 100,000 person-years is estimated to be between 55.3 in 2022 and 67.9 in 2023.
Conclusions:
Hip region stress fractures can also be termed as "private's fractures," which accurately describe their nature. It is crucial to identify cases that necessitate early diagnosis and surgical intervention. Epidemiologically, HSF demonstrates high bilaterality and a bimodal distribution throughout the year. During this period, unit commanders and military doctors should be cautious of HSF among soldiers and conduct appropriate screenings.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
