Minimally Invasive Augmented Fixation for Anatomical Reduction of Grade 2 and Grade 3 Listhesis in Patients with Osteoporosis.

Study Design: A retrospective study.

Purpose: To study the efficacy of augmented fixation for anatomical reduction of grade 2 and grade 3 listhesis in patients with osteoporosis.

Overview Of Literature: Spondylolisthesis in osteoporotic patients requiring spinal fixation are associated with complications such as loss of surgical construct stability, screw pulling out, and screw loosening.

Clinical and radiological assessment of cerebral hemodynamics after cranioplasty for decompressive craniectomy - A Clinical study.

Objectives: To find the correlation between radiologically proven improvement in cerebral hemodynamics with clinical improvement in patients undergoing cranioplasty.

Material And Methods: The study is a prospective observational study of 10 cases, in M S Ramaiah Institute of Neurosciences, involving patients treated by a decompressive craniectomy for intractable intra cranial hypertension either due to trauma or stroke and afterwards underwent cranioplasty.

Results: Of the 10 patients, 70% patients showing significant improvement in motor functions on Barthel index scale, 60% patients showed improvement in speech, mean duration from date of decompressive craniectomy to cranioplasty being 122.

Pneumosinus dilatans of the spheno-ethmoidal complex associated with hypovitaminosis D causing bilateral optic canal stenosis.

Introduction: Pneumosinus dilatans (PSD) is a rare disorder of undetermined etiology characterized by expansion of the paranasal sinuses without bony erosion. Of the few cases of PSD described in indexed pediatric literature, there has been no reported case of this disorder presenting with optic canal stenosis in the setting of a vitamin deficiency.

Case Material: A 12-year-old girl presented with a 3-month history of progressive, painless, and asymmetric visual deterioration in her eyes.

Paediatric calcified intramedullary schwannoma at conus: A common tumor in a vicarious location.

Spinal schwannomas are commonly intradural extramedullary in location. As Schwann cells are not common in the central nervous system, intramedullary schwannomas are a rare entity. In adults, an estimated sixty cases have been reported in English literature.

Giant posterior fossa dural cavernoma in a child.

Purpose: Extra-axial (dural) cavernomas are rare and constitutes 5% of all cavernomas. They are thought to arise from the venous plexus of the dura. They can reach large sizes before diagnosis and can have an aggressive presentation.

Managing a Rare Malignant Sweat Gland Tumor Invading the Brain: Case Report and Literature Review.

Background: Malignant sweat gland adnexal tumors are rare with an incidence of 0.001%. Of these, clear cell hidradenocarcinoma is an extremely uncommon subtype that accounts for 6% of malignant eccrine sweat gland tumors.

Unique paradoxical atlantoaxial dislocation with C1-C2 facet diastases and isolated ligamentous injury to the craniovertebral junction without neurological deficits: A case report.

Study Design: Retrospective review of the case file.

Objective: The primary objective was to report this rare case and discuss the mechanism of dislocation and technique of manual closed reduction of C1-C2 vertebrae in such scenarios.

Summary Of Background Data: Posterior atlantoaxial dislocation (AAD) is extremely rare and a few cases have been reported in English literature.
