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.
Ankle fusion, or ankle arthrodesis, is surgery of the ankle to fuse the bones to treat arthritis and for other purposes. [1] There are different types of ankle fusion surgery. The surgery involves the use of screws, plates, medical nails, and other hardware to achieve bone union. [ 1 ]
Lower screws holding intramedullary rods can sometimes cause limited dorsiflexion as a result of damage and subsequent healing and fibrotic developments around that area. If the bone breaks more medially, there is scope to position the nails further from the ankle joint which would prevent/reduce this dorsiflexion loss.
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]
In medicine, the Ilizarov apparatus is a type of external fixation apparatus used in orthopedic surgery to lengthen or to reshape the damaged bones of an arm or a leg; used as a limb-sparing technique for treating complex fractures and open bone fractures; and used to treat an infected non-union of bones, which cannot be surgically resolved.
A syndesmotic screw is a metal screw designed to replace the syndesmosis of the human body, usually temporarily. If the syndosmosis is torn apart as result of bone fracture, surgeons will sometimes fix the relevant bones together with a syndesmotic screw, temporarily replacing the normal articulation .
Intraoperative X-ray of a humerus fixated by Kirschner wires. Kirschner wires or K-wires or pins are sterilized, sharpened, smooth stainless steel pins. Introduced in 1909 by Martin Kirschner, the wires are now widely used in orthopedics and other types of medical and veterinary surgery.
Grafts are inserted through a tunnel that is drilled through the shin bone (tibia) and thigh bone (femur). The graft is then pulled through the tunnel and fixated with screws. The two bright objects in this X-ray are screws in the thigh bone (above) and shin bone (below). Graft options for ACL reconstruction include:
