Abstract:
Objective:To explore the efficacy of unilateral biportal endoscopic (UBE) decompression combined with percutaneous pedicle screw fixation in the treatment of thoracolumbar burst fracture.Methods:A retrospective series study was conducted on the clinical data of 26 patients with thoracolumbar burst fracture who were admitted to Second Affiliated Hospital, University of South China between January 2023 and June 2024, including 18 males and 8 females, aged 14-58 years [(37.2±12.7)years]. Fractured segments included T 12 in 2 patients, L 1 in 3, L 2 in 9, L 3 in 7, and L 4 in 5. According to the American Spinal Injury Association (ASIA) scale, 2 patients were classified as grade C and 24 as grade D. All the patients were treated with UBE decompression combined with percutaneous pedicle screw fixation. The anterior vertebral height ratio (AVHR), vertebral wedge angle (VWA), kyphosis Cobb angle (KCA), vertebral compression efficiency ratio (VCER), visual analogue scale (VAS) and ASIA grade were compared preoperatively, at 3 days postoperatively and at the last follow-up. Postoperative complications were observed. Results:All the patients were followed up for 6-12 months [(8.7±1.9)months]. At 3 days postoperatively and at the last follow-up, AVHR [(93.7±2.2)%, (88.8±2.5)%], VWA [(3.9±1.2)°, (4.4±1.3)°] and KCA [(5.4±1.4)°, (6.1±1.4)°] were significantly improved compared with those preoperatively [(76.7±3.1)%, (7.0±2.9)°, (12.3±3.4)°, respectively] ( P<0.05). At the last follow-up, AVHR was decreased but VWA and KCA were increased in comparison with those at 3 days postoperatively ( P<0.05). VCER was (18.5±6.9)% at 3 days postoperatively and (18.1±6.4)% at the last follow-up, which were improved in comparison with that preoperatively [(53.6±7.7)%] ( P<0.05). There was no significant difference in VCER at the last follow-up and at 3 days postoperatively ( P>0.05). The VAS score was decreased from (8.5±0.7)points preoperatively to (3.5±0.7)points at 3 days postoperatively and further to (1.0±0.8)points at the last follow-up ( P<0.05), and there was statistically significant difference between the VAS scores at 3 days postoperatively and at the last follow-up ( P<0.05). At the last follow-up, 2 patients with ASIA grade C recovered to grade D, while 24 patients with ASIA grade D recovered to grade E ( P<0.01). Asymptomatic epidural hematoma was found in 1 patient and drainage tube-related limb pain in 1, but no instances of incision infection, cerebrospinal fluid leakage, decreased muscle strength, loosening or breakage of internal fixation were observed in other patients. Conclusion:The combined application of UBE decompression and percutaneous pedicle screw fixation demonstrates significant clinical advantages in treating thoracolumbar burst fractures, including fracture reduction of the injured vertebra, spinal canal decompression, thoracolumbar back pain relief, neurological function recovery and lower complication rates.
