Leprosy, an infectious disease caused by Mycobacterium leprae, affects mostly the skin and peripheral nerves. The polymethylmethacrylate has been used as bone cement, knee and intraocular implants as a bioexpansor, filling the area where it is applied. We describe the case of a Brazilian male with tuberculoid leprosy who developed muscular wasting between the metacarpals of both hands. Ten year...
Some results of the influence of y radiation on the mechanical properties of PoIymethylmethacrylate are presented. Doses of 0, 50, 100, 150 and 200 kGy were employed. The internal friction (loss tangent) and storage shear modulus were measured at temperatures between 173 K and 300 K using a damped torsion pendulum. Compressive tests were made at room temperature with strain rates between 1 . 4 ...
background metastatic spinal tumors are common and major causes of pathological spinal fractures that result in severe pain, weakness, and progressive neurological deficits. this study aims to evaluate the efficacy of percutaneous vertebroplasty (pvp) in pain-relief in patients with spinal fractures due to metastatic spinal tumors. methods we evaluated 25 documented cases of metastatic spinal t...
BACKGROUND AND PURPOSE The presence of a cortical erosion of the posterior wall or an epidural mass is commonly considered a contraindication to performing a vertebral augmentation, considering the perceived increased risk of an epidural cement leak. Our aim was to assess technical and clinical complications of vertebral augmentation procedures performed for pain palliation and/or stabilization...
