The device used to achieve vertebral fixation is usually a permanent rigid or semi-rigid prosthesis made of titanium; examples include rods, plates, screws, and various combinations thereof. A less common alternative is the use of a resorbable fixation device, composed of a bio-resorbable material.
Harrington rods used in spinal fusion. The Harrington rod (or Harrington implant) is a stainless steel surgical device. [1] Historically, this rod was implanted along the spinal column to treat, among other conditions, a lateral or coronal-plane curvature of the spine, or scoliosis. Up to one million people had Harrington rods implanted for ...
Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]
This device consists of a lag screw and a side plate with a barrel. The sliding screw telescopes and provides fixation while allowing impaction to occur at the fracture during healing and weight bearing. Among the complications of sliding screw plate fixation are "cutting out" of the nail, penetration of the screw into the joint, bending or ...
The device can be implanted after a standard decompression by removing the lamina and medial facets in a "posterior arthroplasty" procedure. [3] The TOPS System replaces the bony and soft tissue removed during spinal decompression surgery and implants them at the affected spine segment to aid the patient's flexibility. [4]
Technology: expansion vs. static devices Expandable implant devices are at the forefront of technology in this field, with cages that expand in place for optimal end-plate-to-endplate fit and correction of lordosis. There are several technologies for cage expansion; FLXfit by Expanding Orthopedics offers a unique and patented 3D articulation ...
Fixation in orthopedics is the process by which an injury is rendered immobile. [1] This may be accomplished by internal fixation , using intramedullary rod , Kirschner wire or dynamic compression plate ; or by external fixation , using a spanning external fixator , Taylor Spatial Frame or Ilizarov apparatus .
Spinal fusion, also called spondylodesis or spondylosyndesis, is a surgery performed by orthopaedic surgeons or neurosurgeons that joins two or more vertebrae. [1] This procedure can be performed at any level in the spine (cervical, thoracic, lumbar, or sacral) and prevents any movement between the fused vertebrae.
