Cervical Disc Displacement in Military Pilots.

This article focuses on the incidence and demographic predictors of symptomatic cervical disc displacement (CDD) among active duty U.S. Military pilots, comparing fixed-wing, rotary-wing (helicopter) pilots, and ground-based controls using data from the Defense Medical Epidemiology Database (DMED) from 2007 to 2015. The study found that helicopter pilots have a significantly higher incidence of CDD—3.79 per 1,000 person-years—compared to fixed-wing pilots and non-pilot officers, with risk increasing with age. Despite this increased risk, CDD remains a rare but career-threatening condition that can lead to pilot disqualification. The findings suggest multifactorial causes beyond G-force exposure, including whole-body vibration and wearable equipment, and highlight the need for enhanced education and preventive strategies for helicopter pilots and flight physicians.
