Purpose: Several treatment options have been reported for post-traumatic kyphosis (PTK) and neurologically compromised osteoporotic fractures. However, there is no ideal surgical procedure. This study evaluated the effectiveness of posterolateral decompression and anterior support with a titanium mesh in PTK by posterior surgery.
Materials and Methods: Seventeen patients with PTK and neurologically compromised osteoporotic fractures underwent a single posterior approach. During posterior decompression, a titanium mesh was inserted through the posterior approach after a transpedicular intracorporeal corpectomy. Complications, operating time and blood loss were noted, and radiographic studies and neurological status were evaluated before surgery, after surgery, and at final follow-up.
Results: The mean kyphosis was 35±9.7˚ (range; 17-58˚) before surgery, 3.2±1.8˚ after surgery (correction; 90.5%) and 5.5±3.2˚ at the final follow-up (correction; 85.5%). There was 29.6˚ correction of the kyphosis with a 6% loss of correction. Postoperative neurological improvement using the Frankel classification was demonstrated in all patients. There was no new onset or progressive neurological deterioration, additional surgery or extrusion of mesh. Three complications were encountered: one care each of pneumonia, prolonged ventilator support and distal adjacent vertebral fracture.
Conclusion: The posterior insertion of a titanium mesh for anterior support appears to maintain the length of the anterior column, stabilize the injured vertebra and facilitate spinal fusion. Posterolateral decompression allows as direct a decompression as the anterior approach.
