A 4-mm-long titanium screw with a diameter of 3.75 mm was inserted in the bone behind the ear, and a bone conduction hearing aid was attached. The term osseointegration was coined by Professor Brånemark. During animal studies, he found the bone tissue attached to the titanium implant without any soft tissue in between.
This is a rare but serious complication. In one case, the discitis may have been caused by the use of titanium screws. Signs and symptoms of discitis include chronic back pain and infection. Discitis is treated with intravenous antibiotics and possible removal of the mesh. [5]
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.
Titanium is considered the most biocompatible metal due to its resistance to corrosion from bodily fluids, bio-inertness, capacity for osseointegration, and high fatigue limit. Titanium's ability to withstand the harsh bodily environment is a result of the protective oxide film that forms naturally in the presence of oxygen.
Flatback syndrome is a problem that develops in some patients treated with Harrington rod instrumentation, where the rod extends down into lower part of the lumbar spine. Because the Harrington cannot follow the natural lordosis of the lower back (i.e. the backwaist curve), the spine is straightened out into an unnatural position. At first, the ...
X-ray of interbody fusion cage in cervical vertebrae, Juliet system. X-ray of interbody fusion cage in L5S1 vertebrae. An interbody fusion cage (colloquially known as a "spine cage") is a prosthesis used in spinal fusion procedures to maintain foraminal height and decompression.
Implant that has been used for fixation of a broken wrist. Closed reduction internal fixation (CRIF) is reduction without any open surgery, followed by internal fixation. It appears to be an acceptable alternative in unstable distressed lateral condylar fractures of the humerus in children, but if fracture displacement after closed reduction exceeds 2 mm, open reduction and internal fixation ...
A typical conventional implant consists of a titanium screw (resembling a tooth root) with a roughened or smooth surface. The majority of dental implants are made of commercially pure titanium, which is available in four grades depending upon the amount of carbon, nitrogen, oxygen and iron contained. [22]
