BACKGROUND The association of intraspinal neural anomalies with scoliosis is known for more than six decades. However, there are no studies documenting the incidence of association of intraspinal anomalies in scoliotic patients in the Indian population. The guide lines to obtain an magnetic resonance imaging (MRI) scan to rule out neuro-axial abnormalities(More)
STUDY DESIGN A prospective observational study on the use of Iso-C 3-dimensional navigated surgery in treating 4 patients with spinal osteoid osteomas by a minimally invasive approach. OBJECTIVE To report on the efficacy of Iso-C 3-dimensional intraoperative spinal navigation in excising osteoid osteomas. SUMMARY OF BACKGROUND DATA Curative treatment of(More)
STUDY DESIGN A comprehensive study of 21 lumbar scoliotic discs by in vivo serial post contrast diffusion magnetic resonance imaging (MRI), histopathological, and biochemical analysis. OBJECTIVE To investigate the in vivo effects of compressive and tensile mechanical stress on the lumbar discs with scoliotic disc as the biologic model. SUMMARY OF(More)
Introduction Osteoblastoma accounts for 10% of all spinal tumours occurring most commonly in the cervical spine (40%). It frequently involves the posterior elements and complete excision results in instability necessitating stabilization and fusion [3]. Computer navigation has been shown to be useful in guiding excision of spinal tumours as it allows(More)
BACKGROUND Pedicle screw instrumentation of the deformed cervical and thoracic spine is challenging to even the most experienced surgeon and associated with increased incidence of screw misplacement. Iso-C3D based navigation has been reported to improve the accuracy of pedicle screw placement, however, there are very few studies assessing its efficacy in(More)
Introduction Posterior spinal decompression via expansive laminoplasty is designed to preserve the posterior structures of the cervical spine, so as to prevent postoperative development of instability and cervical kyphosis. The T-saw laminoplasty is a double door laminoplasty using a thin thread saw of 0.54 mm in diameter designed by Katsuro Tomita. A(More)
Introduction Surgical management for thoracic kyphosis is recommended when the kyphosis is greater than 75 or with disabling pain despite conservative management, especially in those who have an unacceptable cosmetic appearance. Surgical treatment of stiff kyphotic deformity may combine anterior release with posterior instrumentation and fusion. However, if(More)
Introduction The surgical stabilization of an odontoid fracture may be done either using an anterior odontoid screw fixation or a posterior C1–C2 fusion. Anterior odontoid screw fixation has the advantages of preserving atlanto-axial motion and is minimally invasive in terms of the exposure and muscle damage. It is imperative that anatomical closed(More)
Introduction Loss of lumbar lordosis in patients with ankylosing spondylitis (AS) can result in severe sagittal alignment deformities often causing inability to look straight ahead with restriction of activities of daily living. Corrective spinal osteotomy may be considered to restore the patient’s balance and ability to see straight ahead. Correction(More)
Introduction There are two major types of surgical procedures for spondylolysis, direct repair for a defect of the pars interarticularis and posterolateral fusion. Pars repair preserves segmental motion and is a less aggressive approach than lumbosacral fusion. Pars repair is thus preferred for patients with a painful spondylolysis without a degenerative(More)
