Abstract accepted for poster presentation at the 2024 Military Health System Research Symposium

Musculoskeletal injuries (MSI) are very common in the military population and even more common with very active and elite paratroopers in the 82nd Airborne Division.  Potter et al. published a one-year prospective cohort study in 2002 in Military Medicine outlining these injuries.  They followed 1,965 paratroopers in from Fort Bragg in 1996. These soldiers suffered 508 overuse injuries (including 38 stress fractures), 1,415 traumatic injuries (including 100 fractures), and 101 unclassified injuries. Injury rates were 6.8% per soldier per month for traumatic injury and 2.4% for overuse injury (totaling 1.2 injuries per soldier per year). Injuries resulted in 22,041 limited duty days, averaging 11 days per injury and 13 days per soldier (4.5% of total workdays). Fractures and stress fractures/reactions produced the most days lost per case. Most of these injuries resulted from military specific activities.

As part of a prospective injury prediction protocol involving knee sensors analyzing single leg stance and a side shuffle task, our Musculoskeletal Injury Rehabilitation Research for Optimal Readiness (MIRROR) team enrolled and screened 1183 soldiers from the 82nd Airborne Division at Fort Bragg/Liberty, NC from fall 2022 to fall 2023 with 6- month and 12-month MSI incidence evaluated in the electronic medical record (AHLTA and Genesis).

These results highlight the types of injuries an active group of soldiers from the 82nd Airborne Division are experiencing and can help to guide prevention and treatment strategies going forward.
