A craniotomy is a surgical operation in which a bone flap is temporarily removed from the skull to access the brain.Craniotomies are often critical operations, performed on patients who are suffering from brain lesions, such as tumors, blood clots, removal of foreign bodies such as bullets, or traumatic brain injury, and can also allow doctors to surgically implant devices, such as deep brain ...
Titanium alloys are susceptible to hydrogen absorption which can induce precipitation of hydrides and cause embrittlement, leading to material failure. [15] "Hydrogen embrittlement was observed as an in vivo mechanism of degradation under fretting-crevice corrosion conditions resulting in TiH formation, surface reaction and cracking inside Ti ...
Metallosis has also been observed in some patients either sensitive to the implant or for unknown reasons even in the absence of malpositioned prosthesis. Though rare, metallosis has been observed at an estimated incidence of 5% of metal joint implant patients over the last 40 years. Women may be at slightly higher risk than men.
Titanium was first used for cranioplasty in 1965. [2] It can be used as a plate or a mesh and be 3D printed as a porous form. [19] Titanium is non-ferromagnetic and non-corrosive, making the host free from inflammatory reactions. [1] It is also robust, thus preventing patients from trauma. [19]
Mayo Clinic is a nonprofit hospital system with campuses in Rochester, Minnesota; Scottsdale and Phoenix, Arizona; and Jacksonville, Florida. [22] [23] Mayo Clinic employs 76,000 people, including more than 7,300 physicians and clinical residents and over 66,000 allied health staff, as of 2022. [5]
Orthopedic surgeon making adjustments to a metal plate in a patient's ankle. An orthopedic plate is a form of internal fixation used in orthopaedic surgery to hold fractures in place to allow bone healing [1] and to reduce the possibility of nonunion. Most modern plates include bone screws to help the orthopedic plate stay in place.
Although stainless steel was used for older IM nails, titanium has several advantages, including lower mechanical failure rates and improved biocompatibility. [6] A more significant problem with earlier designs was their failure to prevent collapse or rotation in inherently unstable fractures.
Epiphysiodesis is a pediatric orthopedic surgery procedure that aims at altering or stopping the bone growth naturally occurring through the growth plate also known as the physeal plate. There are two types of epiphysiodesis: temporary hemiepiphysiodesis and permanent epiphysiodesis.
