Percutaneous Spine Fusion Combined with Whole-Body Traction in the Acute Surgical Treatment of AO A- and C-Type Fractures: A Technical Note.

BACKGROUND

A diminished level of pain following the operation and shortened hospitalization are the distinct advantages of minimally invasive spine surgery (MISS). However, manipulating the spine with additional MISS tools (e.g., distraction and compression devices) is often cumbersome. Our paper draws attention to a cost-free, fast, indirect decompression method that can be used in the acute treatment of thoracolumbar spine fractures. The presented method involves ligamentotaxis by whole-body traction in the operating room combined with percutaneous spine fixation.

METHODS

Fifteen patients with thoracolumbar injuries A type and C type (without distraction) by AO classification were operated sequentially with the combination of whole-body traction and percutaneous minimally invasive spine fixation. Data were analyzed retrospectively.

RESULTS

A total of 139 screws were implanted into 70 segments in 6 female and 9 male patients. The average clinical follow-up was 16 months. Average preoperative traumatic kyphosis was 17 degrees, and an average postoperative kyphosis was 1.8 degrees. The fractured vertebrae's height gain was an average of 11.0 mm (range 3.9-21.9 mm) ventrally and an average of 5.4 mm (range 1-11.2 mm) dorsally after the surgeries. The spinal canal space narrowing showed an average 6.5 mm improvement postoperatively. Operative time averaged 2 hours and 34 minutes, and blood loss averaged 250 mL (range 150-400 mL). No neurologic complications and wound healing problems were observed.

CONCLUSIONS

The combination of MISS and whole-body traction provided successful anatomical correction in thirteen of the fifteen cases of compression type thoracolumbar fractures without extensive surgical exploration.
