Virtual autopsy to assess sacral anatomy: Conditions for a minimal invasive approach to the spinal canal through the hiatus sacralis.

Conclusions: The narrow anteroposterior diameter is the key limiting feature for using the canalis sacralis as a natural entry point into the spinal canal. Sacroscopy will require endoscopes with a flattened shape, with parallel arrangement of instruments and flexibility to accommodate the varied dorsal and ventral curvatures. PMID: 29285406 [PubMed]

ABSTRACTFibrous dysplasia (FD) is a mosaic skeletal disorder resulting in fractures, deformity, and functional impairment. Clinical evaluation has been limited by a lack of surrogate endpoints capable of quantitating disease activity. The purpose of this study was to investigate the utility of18F ‐NaF PET/CT imaging in quantifying disease activity in patients with FD. Fifteen consecutively evaluated subjects underwent whole‐body18F ‐NaF PET/CT scans, and FD burden was assessed by quantifying FD‐related18F ‐NaF activity.18F ‐NaF PET/CT parameters obtained included (i) SUVmax (standardized uptake value [SUV] of t...

ConclusionThis is the first case in the literature to describe a post-laminectomy pseudarthrosis leading to a significant sagittal malalignment in a patient with ochronotic spondyloarthropathy. Management of such a case is challenging as the spine is partially ankylosed; therefore, a long construct is advisable to avoid ankylosing disorders related complications.

Conclusion. When the benefits of one approach over the other are not self-evident, the anterior approach is recommended, as it was associated with a shorter hospital stay and more successful restoration of cervical lordosis than posterior surgery. Level of Evidence: 3

CONCLUSIONS: Given the pathologic anatomy and the biomechanics of LIS, IPD is ineffective in preventing further vertebral body slippage resulting in segmental kyphosis, because of the lack of connection between the posterior arch and the vertebral body due to the isthmic lesion.

ConclusionEarly anterior vertebral body reconstruction for fractures gives better clinical results than delayed reconstruction for patients with diagnosis of nonunion in patients with thoracic and lumbar spine trauma. Moreover, the shorter the time from trauma to operation, the better the sagittal reduction of kyphosis. The use of expandable titanium cage is a good way to perform and maintain this reduction.Level of evidenceIV, retrospective study.

DiscussionReproducibility of our measurement method was found to be excellent. Subsidence was common but without significant clinical effects after 1 year. Nevertheless, subsidence can be associated with pain and can result in loss of lumbar lordosis, which is a potential risk factor for degenerative disease of the adjacent segments. A score for predicting the risk of subsidence will now be developed by our group as a tool for improving patient selection to stand-alone LLIF.Level of evidenceIV, retrospective cohort study.

We present a case of psoas hematoma formation following scoliosis surgery due to intraoperative violation of the intertransverse plane. A 13-year-old female patient with adolescent idiopathic scoliosis underwent a posterior deformity correction and instrumented fusion which was complicated with intraoperative inadvertent violation of the intertransverse plane during dissection of the posterolateral gutter leading to a unilateral psoas hematoma. She experienced abdominal pain and a CT scan confirmed the presence of a psoas hematoma. Antibiotic coverage was provided in view of positive blood culture of Bacillus species to av...

Rationale: Progressive restriction of the spinal bio-mechanics is not-uncommon deformity encountered in spine clinics. Congenital spinal fusion as seen in Klippel-Feil-anomaly, progressive non-infectious anterior vertebral fusion, and progressive spinal hyperostosis secondary to ossification of the anterior longitudinal spinal ligament are well delineated and recognized. Patient concerns: A 24-year-old girl has history of osteoporosis since her early childhood, associated with multiple axial and appendicular fractures and scoliosis. Recently she presented with episodes of severe back pain, spinal rigidity/stiffness wi...
