Non-Traumatic Paraplegia in a First Time Surfer CPT Moses H. Cheng CPT Elizabeth A. Durbin Tripler Army Medical Center March 2007
Introduction • Novice surfers with non-traumatic back pain are at increased risk for paraplegia • There are potentially catastrophic outcomes of back pain
The Case • 37-year old AD male with acute low back pain after attempting surfing for the first time • Pain became severe with transient sensory complaints • Decreased reflexes and unable to ambulate
Arrival at Tripler (6 hours after initial symptoms) • Lower extremity neuro exam • Decreased muscle strength (3/5) • Absent dorsiflexion • Minimal plantarflexion • Intact sensation • Unequal patellar reflexes • Absent Achilles and Babinski • Poor rectal sphincter tone • L-spine plain films and CT L/S-spinenormal
Worsened lower extremity deficits Bilateral strength 1/5 Sensory loss L4 to S5 Hospital Course
Initial MRI • MRI L-spine • Consistent with cord ischemia
MRI at 48 hours • Transferred to ICU • Paraplegia to T11
Discussion • Surfing injuries are primarily traumatic in nature • Contact with surfboard • Collision • Hydrodynamic forces • Impact with the ocean floor • Incidence of head and neck injuries is 34%-37% • Most craniospinal injuries are secondary to impact with the sand or being hit by a surfboard (JAMA, 1977)
Surfer’s Myelopathy Unique syndrome involving a first time surfer who develops non-traumatic back pain and paraparesis with sensory and urinary symptoms
Literature Review • Thompson TP, et al. Spine, 2004. • Case series of 9 patients with non-traumatic paraparesis/paraplegia • All were first time surfers • Gender: 8 male, 1 female • Age: 21-30 years • All had increased signal on MRI from low thoracic vertebra to conus medullaris • One with residual paraplegia
Postulated Mechanism Prolonged prone hyperextension of back and neck can cause ischemia of spinal cord • Infarction of watershed areas of perfusion • Avulsion of perforating vessels • Vasospasm of artery of Adamkiewicz
Why Novice Surfers? • Only 4-5% of time surfing involves wave riding • 50% spent paddling out • 40% spent stationary • Novice surfers spend extensive time lying prone with neck and back hyperextended
What Our Report Adds • Initial symptoms may be delayed in presentation • Our patient developed pain after exiting the water • Our case validates a potential grim prognosis • Previous series had 1 out of 9 with residual paraplegia
Conclusion • Novice surfers are at risk for spinal cord injury • Body position while surfing is a risk factor for cord injury • Early recognition and consultation • Goal to ensure perfusion of cord • Prevention through education of risks and proper technique
