Biographical profile of Jacquelin Perry MD, DSc, one of the first women board-certified in orthopedic surgery. Traces her path from Army physical therapist to co-developer of the halo device, founder of the Pathokinesiology Laboratory, and global authority on gait biomechanics. Covers her academic legacy, mentorship, and the Perry Initiative for women in orthopedics and engineering.
The halo device is a routine tool in cervical spine trauma management today. Its origin was a practical intraoperative problem Perry encountered with polio patients in the 1950s — spines that collapsed without surgical fixation, in patients who could not safely receive anesthesia.
For trainees managing cervical instability: the halo provides rigid external immobilization as a bridge or definitive treatment when operative stabilization is not immediately feasible.
Perry's work on dynamic EMG for tendon transfer planning in cerebral palsy remains clinically relevant. Pre- and postoperative EMG identifies which muscles are phasically active and which are spastic, preventing transfers that would create new deformity.
Her textbook Gait Analysis: Normal and Pathological Function is the reference for understanding pathological gait patterns. A core skill for any orthopedic surgeon managing CP, stroke, or neuromuscular disease.
