Area of Science:

Neurosurgery
Spinal Surgery

Background:

Spinal kyphosis can lead to neurological deficits.
Existing surgical approaches may compromise pulmonary function.

Purpose of the Study:

To describe a direct internal kyphectomy using a modified costotransversectomy.
To evaluate the safety and efficacy of this extrapleural approach for treating kyphosis with paraparesis.

Main Methods:

A modified costotransversectomy was performed as an extrapleural approach.
Resection of ribs and pedicles at the kyphotic apex.
Decompression of the spinal canal and posterior vertebral body removal.
Cortical strut grafting for anterior fusion.

Modified Posterior Vertebral Column Resection for Patients with Thoracolumbar Kyphotic Deformity

Published on: September 16, 2022

Main Results:

Five patients with paraparesis due to healed disease were treated.
Preoperative mean kyphosis was 114 degrees.
Neurological improvement was observed in two patients.
Solid anterior fusion was achieved in four out of five patients at a mean 5-year follow-up.
One patient experienced a fatal chest infection post-surgery.

Conclusions:

The modified costotransversectomy offers an extrapleural approach for internal kyphectomy.
This technique can be considered for kyphosis with neurological compromise.
While effective for fusion, potential complications like infection require careful management.
