Cement Salvage of Instrumentation-Associated Vertebral Fractures [PDF]
American Journal of Neuroradiology, 2014 Spinal instrumentation plays a key role in the treatment of spinal instability in patients with metastatic tumors. Poor bone quality, radiation, and diffuse osseous tumor involvement present significant challenges to spinal stabilization with instrumentation and occasionally result in postinstrumentation compression fractures.

A novel technique for removal of broken instrument from root canal in mandibular second molar
Indian Journal of Dental Research, 2014 The fracture of an endodontic instrument is an obstacle in completion of a routine successful pulp space therapy. Ni-Ti instruments corrode when in contact with sodium hypochlorite which leads to their deterioration and ultimately fracture during use ...

Posterior Instrumentation of Thoracolumbar Fracture
Journal of Korean Society of Spine Surgery, 2001 The thoracolumbar spine remains the most common site of vertebral column injuries. Surgical stabilization using posterior instrumentation for thoracolumbar injuries offers several advantages such as nearly anatomical reduction of fractures, protection of neurologic function and most important early ambulation of the patient, and so major benefits of ...
