Original Uniportal Bichannel and Dual-Media Spinal Endoscopy System Assists Elderly Patients with Thoracolumbar Kyphosis Associated with Osteoporosis: Technical Note and Preliminary Clinical Results.

Abstract

The uniportal bichannel and dual-media spinal endoscopy (UBD) system is an original endoscopic system developed by the authors. This technical note describes a single-center case series of elderly patients with thoracolumbar kyphosis (TLK) with osteoporosis treated with the assistance of the UBD system. This article presents a retrospective case series including 4 patients with TLK with osteoporosis treated with assistance of the UBD system. Demographic, clinical, imaging, and procedure-related data are reported. All 4 patients achieved satisfactory correction of TLK. The regional kyphosis angle and TLK improved significantly in the patients, correcting from 24.73 ± 6.51° to 5.46 ± 2.16° (P < 0.001) and 29.28 ± 4.02° to 6.33 ± 3.13° (P < 0.001). The patients showed an improvement in visual analog scale and Oswestry Disability Index scores postoperatively (P < 0.001). No complications were observed. This study suggests that use of the UBD system to assist in treatment of elderly patients with rigid TLK with osteoporosis is a safe and effective approach.
