Unfortunately, current literature does not yet establish a validated and minimally invasive surgical intervention for this issue. This study aims to investigate the effects of a novel hollow pedicle screw combined with kyphoplasty (HPS\u2010KP) in preventing bone cement displacement following simply percutaneous kyphoplasty for the management of KD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 22 patients (six males, 16 females, averagely aged 77.18\u2009\u00b1\u20097.63\u2009years) with KD without neurological deficits treated by HPS\u2010KP at the hospital between March 2021 and June 2022 were hereby selected, among which, there were three stage I KD cases, 12 stage II KD cases, and seven stage III KD cases according to Li's classification. Bone mineral density (BMD), spinal X\u2010ray, computed tomography (CT), and magnetic resonance imaging (MRI) were examined before the operation. The operation time, intraoperative blood loss, and postoperative complications were all recorded. The follow\u2010up focused on visual analog scale (VAS) score, Oswestry dysfunction index (ODI), anterior vertebral height (AVH), middle vertebral height (MVH), posterior vertebral height (PVH), wedge\u2010shape affected vertebral Cobb angle (WCA), and bisegmental Cobb angle (BCA). One\u2010way analysis of variance (ANOVA) followed by Bonferroni post\u2010hoc test was employed for performing multiple comparisons in the present study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All patients having received the operation successfully were followed up for more than 8\u2009months (ranging from 8 to 18\u2009months).
