The Use of Percutaneous Stent-Kyphoplasty (SpineJack®) in Osteoporotic and Non-Osteoporotic Vertebral Fractures: A Retrospective Analysis of 310 Implants From a Level-1 Trauma Center in Switzerland.

Study DesignRetrospective cohort study.ObjectivesThe SpineJack®-system represents a new generation of kyphoplasty for the treatment of traumatic and osteoporotic fractures. The aim of this study was to analyze the usage, safety and efficacy of the SpineJack®-system, in both osteoporotic and non-osteoporotic fractures.Methods310 patients with vertebral fractures treated with the SpineJack®-system between November 2014 and December 2022 were analyzed. Demographics, intraoperative parameters and outcomes were assessed. A subgroup analysis was performed for traumatic vertebral fractures (tVCFs) and osteoporotic vertebral fractures (oVCFs).ResultsSpineJack®-kyphoplasty was performed for 157 (47.4%) oVCFs and 153 (46.2%) tVCFs. Stand-alone SpineJack®-kyphoplasty was performed in 128 patients, while 182 patients underwent combined procedures. The mean pain reduction from admission to discharge was 3.8 (range 3-10, SD 2.7). Opioids were administered for an average of 4.6 days (range 0-72 days, SD 7.2 days). The overall mean hospital length of stay was 6.1 days, significantly shorter for patients undergoing stand-alone SpineJack® procedures at 4.8 days (SD 6.9 days). The most common complication observed was cement extravasation in 29 patients (8.8%), followed by neurological symptoms in 8 patients (2.4%) and surgical site infections in 4 patients (1.2%). Notably, no surgical site infections were recorded in the stand-alone SpineJack®-group.ConclusionPercutaneous stent-kyphoplasty (SpineJack®-system) appears to be a safe and effective therapeutic option, whether used as a stand-alone procedure or in combination with other interventions, for osteoporotic and non-osteoporotic vertebral fractures.
