[Percutaneous kyphoplasty using expandable SpineJack® implant for the treatment of osteoporotic vertebral fractures].

The purpose of this study was to assess the outcome of surgical management of osteoporotic vertebral fractures with percutaneous kyphoplasty using expandible SpineJack® implant. We conducted an analytical retrospective single-center study over a period of 33-months (April 2015 - December 2017). It involved patients treated with kyphoplasty for an osteoporotic vertebral fracture. The kit consisted of a Vexim SpineJack® expandable titanium implant and acrylic cement. Patients with back pain increasing in intensity despite treatment for an osteoporotic vertebral fracture were included in the study as well as those who had undergone surgery and had given their informed consent. The vertebral fracture was diagnosed based on CT scan results and its recent state was confirmed by MRI. Between april 2015 and december 2017, thirty-seven patients with osteoporotic vertebral fractures were treated with kyphoplasty using expandable titanium vertebral implant. The average age of patients was 73.4 years, with a sex ratio of 0.6. Mean visual analog scale score was 7.3. Mean Oswestry score was 81.6. The patients mainly had fractures of the thoracolumbar hinge. Mean vertebral kyphotic angle was 18.45°. Kyphoplasty was used for the treatment of 44 vertebrae. Four patients had surgical complications. The average length of stay in hospital was 5.4 days. After a follow-up period of 6 months, 9 patients were still receiving analgesic therapy. After one year, no adjacent level fracture was found. Percutaneous kyphoplasty using expandible titanium implant is a safe and effective therapeutic mean for osteoporotic vertebral fractures. Given its almost immediate result, patients can rapidly get back to their active lives.
