T3 Burst Fracture after Motor Vehicle Accident

History

A 32-year-old woman presented to the emergency room after a rollover motor vehicle accident. She was instantly paralyzed in her lower extremities. She had no sensation below the clavicles, and she had severe neck pain.

Examination

On examination, she had no lower extremity movements (ASIA A) with a complete sensory level at T2-T3. Reflexes were depressed. She had no anal tone or bladder sensation.

Pre-treatment Images

Figures 1-3 show a complex T3 burst fracture with almost complete retropulsion of the T3 vertebral body into the spinal canal. There is a severe kyphotic deformity at this level, and the canal is obliterated.

Diagnosis 

The patient was diagnosed with a T3 burst fracture.

Selected Treatment

The patient underwent posterior single-stage reconstruction and stabilization.

After initial exposure, a transpedicular vertebrectomy of T2 and T3 was effected. T2 was included because of the edema in the vertebra on the MRI scan.

Pedicle screws were placed at C7, T1, T4, T5, and T6. To allow for reduction and also to preserve lower cervical levels, 6.5 mm screws were placed at each level. Using a temporary reduction rod and traction through Gardner Wells tongs to 70 lb, the deformity was corrected.

An expandable cage was placed posteriorly from T1-T4 and packed with local autograft.

The case was performed with AP fluoroscopy only. No navigation system was used.

She had no new deficit post-operatively and was not braced.

Outcome

The patient had no neurological recovery, but her pain settled. Three months post-operatively, her x-rays were satisfactory, as seen in the above section.

 

Case Discussion

This is a really interesting, challenging case with a severe burst fracture at T3 and complete paraplegia. It appears that besides the clearly apparent burst fracture at T3, there probably is a fracture at T2 also. An axial CT of T2 might confirm the same.

Given the high thoracic level of the fracture and the considerable moribidity associated with an anterior approach at T2 and T3, I would agree with the author on approaching this posteriorly. If the patient had neurological preservation or incomplete injury, then personally, I would probably approach this in the traditional anterior fashion in order to avoid any manipulation of the cord whatsoever. Given the fact the patient had a complete spinal cord injury and the main goal was providing stabilization, the posterior approach is a sound and reasonable option.

The author has obtained an excellent re-alignment and stabilization and should be commended for the same.
