Vertebroplasty with Calcium Composite Bone Graft Combined with Pedicle Screws Fixation in Thoracolumbar Fractures
Introduction: Posterior reduction probably reduces only the periphery of the endplate with its strong annular attachments while the central area remains depressed allowing for efficient realignment of the spine, direct and indirect decompression. With distraction force, restoration of vertebral body height and partial clearance of bone or discal fragments from within the spinal canal by ligamen...
متن کاملComparison of the bone response to xenogenic bone screws and metallic screws in canine femur
The study compared the bone response to xenogenic screws and metallic screws of a similar design in a canine femur. The xenogenic bone screws and metallic bone screws were inserted into the femur diaphyses of dogs. Radiological and histological responses to the xenogenic bone screws were determined in canine bone and micro-computed tomography evaluation of bone mass and bone density parameter w...
متن کاملUnconventional fixation of thoracolumbar fractures using round hole bone plates and transpedicular screws.
BACKGROUND In an attempt to contain the high cost of commercially available pedicle screw systems, several authors have used unconventional alternatives such as locally made plates or dynamic compression plates (DCP) along with cancellous screws for transpedicular fixation of the thoracolumbar spine. These plates, however, allow for a wide range of motion at the plate-screw interphase and the c...
متن کاملUse of resorbable plates and screws in pediatric facial fractures.
PURPOSE The use of resorbable plates and screws for fixation of pediatric facial fractures is both well tolerated and effective. It enables realignment and stable positioning of rapidly healing fracture segments while obviating any future issues secondary to long-term metal retention. PATIENTS AND METHODS Forty-four pediatric facial fractures were treated over a 10-year period at our institut...
متن کاملFar cortical locking screws in distal femur fractures.
Distal femur fractures routinely heal by secondary bone healing, which relies on interfragmentary motion. Periarticular locking plates are commonly used for fixation in distal femur fractures but are associated with a high nonunion rate, likely due to the stiffness of the constructs. Far cortical locking (FCL) screws are designed to allow micromotion at the near cortex while maintaining purchas...
