STUDY DESIGN: A case of lower-extremity @entity602 induced by physical exertion in a @entity1 with Type 2 (failure of segmentation) @entity1513 is reported. OBJECTIVE: To describe the uncommon presentation of neurologic sequelae in a @entity1 with @entity1513 . SUMMARY OF BACKGROUND DATA: Various reports have described neurologic sequelae in @entity1 with Type 1 (failure of formation) @entity1513 . To the authors' knowledge, no case of @entity1513 leading to @entity16 has been reported. METHODS: A 17-year-old @entity1 presented with a 3-year history of progressively worsening @entity615 . During exertion, numbness developed along the posterior aspects of his legs, and he experienced a wobbly sensation in his lower extremities that prevented his participation in athletic activities. His static and dynamic neurologic examination was unremarkable. However, he developed a wide-based clumsy myelopathic gait when he was asked to run in the halls of the clinic. Magnetic resonance imaging demonstrated that the spinal cord was draped over the posterior vertebral body of T10. Anterior thoracic spinal cord decompression and fusion were performed through a seventh rib thoracotomy using a structural rib graft to fill the defect. The anterior 1 cm of bone was left intact so as not to cause any additional instability. RESULTS: The @entity1 tolerated the procedure well and had complete resolution of his exertionally dependent @entity1109 . At this writing, 3 years after surgery, he is involved in the Navy ROTC program. CONCLUSIONS: Although @entity1513 is a rare entity, it should be followed carefully and corrected surgically when appropriate. A history of exertional @entity602 may be an early sign of spinal cord impingement and is an indication for surgical decompression.
