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 tension band wire is a form of orthopaedic internal fixation [1] method used to convert distraction forces into compression forces, promoting bone healing. [citation needed] Olecranon fracture; Patella fracture; Malleolar fracture

In the longer term, the knee may not regain full movement, pain may persist and there is an increased likelihood of osteoarthritis of the knee. [7] If there is an associated open wound as in an open fracture , complications also include risk of infection, inability of the broken bones to reunite and osteonecrosis .
When a bone fractures, the fragments lose their alignment in the form of displacement or angulation. For the fractured bone to heal without any deformity the bony fragments must be re-aligned to their normal anatomical position. Orthopedic surgery attempts to recreate the normal anatomy of the fractured bone by reduction of the displacement.
Total knee replacement is also an option to correct significant knee joint or bone trauma in young patients, [7] treat complex fractures in elderly, either due to previous symptomatic osteoarthritis or situations where internal fixation with plates and screws is deemed too hazardous. [8]
Historically, knee and hip arthrodeses were also performed as pain-relieving procedures, but with the great successes achieved in hip and knee arthroplasty, arthrodesis of these large joints has fallen out of favour as a primary procedure, and now is only used as a procedure of last resort in some failed arthroplasties.

An intramedullary rod, also known as an intramedullary nail (IM nail) or inter-locking nail or Küntscher nail (without proximal or distal fixation), is a metal rod forced into the medullary cavity of a bone. IM nails have long been used to treat fractures of long bones of the body.
