Panner's disease tends to be self-limiting and presents as a focal osteonecrosis of the entire capitellum
63) The ulna is displaced posteriorly relative to the humerus, resulting in impaction of the coronoid process against olecranon and posterior capitellum
against the radial head (Figure 13).
In the early stages, when the main complaint is pain without loss of motion and there is oedema in the capitellum
on MRI, rest and anti-inflammatories are all that are required.
The radial head, capitellum
view: useful technique in elbow trauma.
The precise etiology of osteochondritis dissecans of the capitellum
is not entirely understood.
McKee, "Fractures of capitellum
and trochlea," Orthopedic Clinics of North America, vol.
Due to the acute nature of the patient's pain and the extreme difficulty moving her elbow, she was referred for ultrasound and radiographic imaging to rule out more sinister differentials (osteochondritis dissecans of the capitellum
or radiocapitellar arthritis).
This results in posterolateral rotatory instability, where the radial head subluxes posteriorly off the capitellum
MRI revealed erosions of the articular surfaces of the radial head and capitellum
and decreased subchondral marrow signal that is isointense to the surrounding muscle (Figure 1).
On x-ray, the capitellum
looks fragmented and rocky Get a CT scan to rule out a tumor.
Evaluating the relationship of the capitellum
to the distal humerus makes the diagnosis.
Flattening of the capitellum
was demonstrable on the lateral view.
In 2007, surgeons are, for the first time, using SBi's new UNI-Elbow[TM] Radio Capitellum
In addition, other criteria like the restriction of the clear space between olecranon and capitellum
and transaction of the capitellum
by anterior humeral line on the lateral radiograph were also employed.
