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.
Internal fixation refers to fixation of screws and/or plates, intramedullary rods and other devices to enable or facilitate healing. Rigid fixation prevents micro-motion across lines of fracture to enable healing and prevent infection, which happens when implants such as plates (e.g. dynamic compression plate) are used.
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 ]
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]
The ankle joint is then turned 180 degrees and is reattached to the thigh. [30] They are held together by plates and screws until they have healed naturally. The surgery can take anywhere from 6–10 hours, with a day or two in intensive care. [26] The leg is kept in a cast for 6–12 weeks.
The sliding screw plate (dynamic compression screw, dynamic hip screw) may be used to treat intertrochanteric fractures as well as other injuries. 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 ...
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.
X-ray of trimalleolar fracture repair with plate and nails. Surgical repair using open reduction and internal fixation is generally required, and because there is no lateral restraint of the foot, the ankle cannot bear any weight while the bone knits. This typically takes six weeks in an otherwise healthy person, but can take as much as twelve ...
