PCKP has less risk of cement leakage than UPKP in treatment of vertebral compression fractures: study
Osteoporotic vertebral compression fractures (OVCFs) have become a significant public health concern due to the high morbidity and limited efficacy of conservative treatment. Conventional unilateral percutaneous vertebral kyphoplasty (UPKP) is beset by technical limitations, including the uneven distribution of cement and the inherent risk of leakage. Conversely, percutaneous curved kyphoplasty (PCKP) involves the creation of an accessible contralateral bone tunnel through a curved bone auger, a technique that, in theory, optimizes cement distribution. However, the clinical benefits of PCKP remain a subject of debate.
Yang Fuguo et al conducted a study to prospectively compare the difference in near- and midterm efficacy between PCKP and UPKP for the treatment of single-segment OVCFs, and to clarify the clinical value of PCKP.
A total of 89 patients with single-segment OVCFs were divided into two groups: the PCKP group (n = 43) and the UPKP group (n = 46). At the 12-month follow-up, pain visual analog scores (VAS, Oswestry Dysfunction Index (ODI)) and cement distribution were assessed preoperatively, at 2 days, 3 months, and 12 months postoperatively. The duration of surgery was recorded, as were the number of fluoroscopy, bone cement dose, and complications. Compare the two sets of parameters.
