Comminuted Femur Fracture in a Free Fall Jump: A Case Report

Military free fall or high-altitude low-opening parachute jumps play a key role in special operations tactics, though injury patterns in these operators are not well characterized. In contrast to lower-altitude static line paratroopers, free fall operators require precise parachute deployment after a prolonged descent, with the potential for high-velocity trauma. This report describes a 33-year-old Marine Corps Reconnaissance operator who sustained left comminuted basicervical femoral neck fracture requiring cephalomedullary nail internal fixation with a full recovery. This femoral neck fracture highlights the high-energy injuries experienced by these invaluable operators, especially when conducting combat or night jumps.
