Integration of small needle knife in treating inflammatory factors, Th17 cell function, and magnetic resonance imaging evaluation in osteoporosis complicated by compression fractures in elderly patients.

Objective: The incidence of osteoporosis complicated by vertebral compression fractures (OVCF) has been increasing annually, and percutaneous vertebroplasty (PVP) is the main surgical approach for it. It was to evaluate the use of a small needle knife (SNF) in conjunction with PVP to assess changes in inflammatory response, Th17 cell function, and magnetic resonance imaging (MRI) parameters in OVCF patients.

Methods: A retrospective analysis was conducted using the clinical data of 138 patients with OVCF, who were categorized into PVP group (n = 65) and PVP + SNF group (n = 73).
