The aim of this study was to evaluate the efficacy and safety of modified posterior vertebral column resection (PVCR) combined with anterior column restoration in elderly patients presenting with thoracic or thoracolumbar osteoporotic fractures with spinal cord compression and severe pain. Methods: 109 patients with one level thoracolumbar osteoporotic fracture and at least 5 years of follow-up were included. They underwent posterior instrumentation performed with PMMA augmented pedicle screws. A modified PVCR (unilateral costotransversectomy+hemilaminectomy) combined with the insertion of an expandable titanium cage for anterior column restoration was undertaken. Patients were evaluated clinically and radiographically. Results: Patients had a with a mean age of 74.1 and follow-up duration of 92.3 months. Mean duration of operations, hospital stays and mean loss of blood were detected as 172.3 minutes, 4.3 days and 205.4mL. All of the patients were mobilized immediately after surgery. The mean pre-operative local kyphosis angle improved from 39.3 to 4.7 at the last follow-up (p=0.003). Patients pre-operative mean VAS, JOA and ODI scores improved from 7.7/8.6/76.3 to 1.6/26.1/17.4(p<0.001 for all), respectively. The average SF-36 MCS/PCS scores at the last follow-up were 55.1/56.8. Dural tear was detected intra-operatively in one patient and repaired immediately. Conclusion: Subtotal PVCR combined with the insertion of an expandable titanium cage was detected as a safe and effective method for osteoporotic vertebrae fractures' sequelae in elderly population involving spinal cord compression, by enabling the decompression of the A c c e p t e d A r t i c l e 2 spinal canal and reconstruction of the resected segment, resulting in significant improvement in clinical and radiographic outcomes.
AIM:To understand the late anatomical results of surgically treated intracranial aneurysms (IA's) and to investigate the incidence of recurrent, de novo aneurysms, the natural history of residual aneurysms, and the morphological changes in temporarily clipped vascular segments.
MATErIAL and METHods:A total of 117 patients underwent screening with digital subtraction angiography (DSA) or computed tomographic angiography (CTA) in a range of 3 -13 years. Late angiographies were evaluated in terms of recurrence, change in known residua, the presence of de novo aneurysms and the morphological changes in temporarily clipped vessels. We also analysed the cumulative data including previously published results.
rEsuLTs:In the long-term DSA, three residual aneurysms were observed to be enlarged while four remnants showed no morphological change. In one patient, spontaneous obliteration was seen. No recurrent aneurysm was detected. One de novo aneurysm was observed. We did not find any morphological change in 71 temporarily clipped vascular segments.
CoNCLusIoN:Our data demonstrates that completely occluded aneurysms could remain stable even years later. Most of the small neck residues appeared to remain unchanged or even be thrombosed but they should be carefully followed. The incidence of de novo aneurysms might be expected to be lower.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
