A Novel Device for Closed Reduction and Percutaneous Fixation of Thoracolumbar Fractures

In Vivo. 2022 Jan-Feb;36(1):384-390. doi: 10.21873/invivo.12715.

Abstract

Background/aim: Open surgical reduction/fixation of thoracolumbar fractures results in significant soft-tissue trauma and related complications. Minimally-invasive technical developments could deliver similar radiological outcomes, while avoiding the related complications. We evaluated radiological and perioperative outcomes in thoracolumbar fractures by using a novel minimally-invasive device.

Patients and methods: Twenty-six patients with 29 thoracolumbar fractures using the NForce device were analyzed. Postoperative reduction and alignment were assessed by radiographic measurement of the local kyphosis angle (LKA) up until a follow-up period of 9 months.

Results: Postoperative imaging revealed an average reduction of traumatic kyphosis of 8.25° (±7.72°) with an average postoperative LKA of 3.24° (±8.97°). The highest degree of reduction was 27.39°. The mean LKA had increased to 5.08° (±5.17°) at 3 months postoperative, 5.43° (±4.32°) at 6 months and 6.21° (±3.82°) at 9 months.

Conclusion: The minimally invasive NForce system is effective in performing anatomic percutaneous reduction/fixation.
