Rare Indication of Atlantoaxial Fusion-failed Conservative Management of Primary Atlantoaxial Osteoarthritis.

Introduction: Osteoarthritis of the atlantoaxial joint is a significant cause of occipitocervical pain, which is often missed and has an increasing prevalence with age. The patients typically present with occipitocervical pain and restricted and painful neck rotations. Despite the primary reliance on conservative management for this pathology, surgical intervention becomes crucial for those not responding to standard conservative treatment.

Malignant Conversion to Glioblastoma in Neurofibromatosis Type I-associated Pleomorphic Xanthoastrocytoma: Unknown Predictors of Favorable Outcome.

Pleomorphic xanthoastrocytoma (PXA) is a benign glial tumor, the association of which with neurofibromatosis type I (NF-1) has been often reported in the literature. Although malignant conversion to glioblastoma may be seen in 5%-10% of PXA, the same has been reported only once in the presence of NF-1. We report, so far known to be only the second such case all over.

Ultrasonic bone scalpel: utility in cervical corpectomy. A technical note.

Purpose: Anterior cervical corpectomy and fusion (ACCF) is a technically challenging surgery. Use of conventional instruments like high-speed burr and kerrison rongeurs is associated with high complication rates such as increased blood loss and incidental durotomy. Use of ultrasonic bone scalpel (UBS) in cervical corpectomy helps to minimize such adverse events.
