Percutaneous vertebral-disc plasty for very severe osteoporotic vertebral compression fractures / 中华创伤骨科杂志

ABSTRACT

Objective:To investigate the clinical efficacy of percutaneous vertebral-disc plasty (PVDP) in the treatment of very severe osteoporotic vertebral compression fractures (vsOVCF).Methods:A total of 26 patients with vsOVCF were treated by PVDP at Department of Spine Surgery, The Second Affiliated Hospital, Nantong University from November 2019 to August 2021. They were 8 males and 18 females with an age of (77.9±5.2) years. Fracture sites T11 in 9 cases, T12 in 13 cases, L1 in 7 cases, and L2 in 2 cases. The loss of vertebral height exceeded 2/3 of its original height. The curative effects were evaluated by comparing the visual analogue scale (VAS), Oswestry disability index (ODI) and local kyphosis angle (LKA) at preoperation, 1 day postoperation and the last follow-up.Results:This cohort was followed up for 12(10, 15) months. No obvious neurological damage or other serious complications occurred. The VAS scores [(2.9±0.7) and (2.2±0.7) points] and ODIs [28.0%±4.8% and 16.9%±4.0%] at 1 day postoperation and the final follow-up were significantly lower than the preoperative values respectively [(6.7±0.8) points and 66.7%±6.0%], and the values at the last follow-up were significantly lower than those at 1 day postoperation ( P<0.05). The LKAs at 1 day postoperation and the last follow-up (18.1°±4.1° and 19.5°±4.4°) were significantly smaller than that before operation (32.0°±5.2°) ( P<0.05), but there was no significant difference between 1 day postoperation and the last follow-up in LKA ( P>0.05). Conclusion:PVDP is an effective surgical treatment of vsOVCF, because it can relieve pain and improve local kyphosis with satisfactory clinical outcomes.
