The metaphysis (pl.: metaphyses) is the neck portion of a long bone between the epiphysis and the diaphysis. [1] It contains the growth plate , the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses.
Fracture of the cartilage of the physis (growth plate) II – A = Above. The fracture lies above the physis, or Away from the joint. III – L = Lower. The fracture is below the physis in the epiphysis. IV – TE = Through Everything. The fracture is through the metaphysis, physis, and epiphysis. V – R = Rammed (crushed). The physis has been ...
A corner fracture or bucket-handle fracture is fragmentation of the distal end of one or both femurs, with the loose piece appearing at the bone margins as an osseous density paralleling the metaphysis. [8] The term bucket-handle fracture is used where the loose bone is rather wide at the distal end, making it end in a crescent shape. [9]
These fractures are the most common of the three groups mentioned above that require surgical management. [5] A minimal articular fracture involves the joint, but does not require reduction of the joint. Manipulative reduction and immobilization were thought to be appropriate for metaphyseal unstable fractures.
Proximal fractures of the fifth metatarsal are common, [2] and are distinguished by their locations: A proximal diaphysis fracture is typically a stress fracture, commonly among athletes. [3] [4] A metaphysis fracture is also called a Jones fracture. Due to poor blood supply in this area, such a fracture sometimes does not heal and surgery is ...
Metaphyseal dysplasia, or Pyle disease, [3] is a disorder of the bones. It is a rare disease in which the outer part of the shafts of long bones is thinner than normal and there is an increased chance of fractures .
In metaphyseal areas, delayed signs of fracture include a band of sclerosis perpendicular to the trabeculae, while diaphyseal fractures may present as periosteal thickening. [ 1 ] Digital radiography known as tomosynthesis has been shown to be superior to conventional radiographs in the detection of occult fracture of the scaphoid.
Simple articular, complex metaphyseal Complex articular, complex metaphyseal Subgroups are then used to describe the fractures in terms of displacement (versus apposition, which is the degree to which the parts are in contact with each other), rotation, angulation and shortening.
