ABSTRACT
Background: The incidence of vertebral fragility fracture is increasing over last three decades with an essential impact on quality of life. Some devices were proposed to improve conventional kyphoplasty in the last five years, known as vertebral stenting kyphoplasty (VSK). Materials and Methods: All osteoporotic vertebral fractures (OVF) treated with VSK, single-level fracture without neurological impairment, and with more than 24 months of follow-up were included in the study. We recorded fracture types according to DGOU classification, fracture level, regional kyphosis angle (RKA), Oswestry disability index (ODI), and complications. Results: Forty-seven consecutive patients were included. RKA significantly improved from pre to postoperative values (p<0.000001) and to follow-up values (p<0.00001). A significant difference was found between preoperative RKA of (OF2+OF3) and OF4 (p<0.00001), confirmed immediately after surgery (p= 0.005425) and at last follow up (p= 0.000947). A significant difference was found in correction of RKA between (OF2+OF3) and OF4 at injury time and after treatment (p<0.00001), and it was confirmed at the last follow-up (p=0.000026). ODI showed a significant difference between (OF2+OF3) and OF4 type of fractures (p=0.038216). We recorded five complications: 2 cases of leakage without neurological impairment, two progressions of kyphosis, and one implant migration. Conclusions: VSK is an excellent and reliable option in the treatment of OVF, with good clinical results and preservation of obtained RKA at the time of treatment. However, in case of vertebral collapse with the involvement of both vertebral plates, surgeons must be aware of possible implant failure or migration. Level of Evidence: 4.
ABSTRACT
Study DesignRetrospective comparative study.PurposeThis study aimed to compare clinical and radiological data and rate of mechanical complications in elderly patients treated with short segment (SSS) or long segment stabilization (LSS) for thoracolumbar junction osteoporotic vertebral fractures (OVFs).Overview of LiteratureA fervent debate is now focused on the treatment of OVF using SSS or LSS. High rate of complications is associated with pedicle screw fixation because of poor bone quality.MethodsPatients over 65 years old with a T-score of ResultsA total of 37 patients met the inclusion criteria. Mean follow-up was 33.97±9.26 months. For both groups, ODI and VAS significantly decreased over time with good results (pp=0.046), whereas no difference was found in SSS group. A significant difference in the rate of mechanical complications was found between groups (p=0.011).ConclusionsBoth treatments showed good clinical and radiological results; however, LSS group showed better BKA correction and lower mechanical complications than SSS group.
