Q. 'Perched' injury is related to which structure in below image?
a. Radial head
b. Proximal radioulnar joint
c. Radiocapitellar joint
d. Ulnohumeral joint
Answer -
d
The spectrum of elbow joint dislocation ranges from subluxation then perched elbow( when the trichlea is perched over the coronoid but still not dislocated) and followed by dislocation in more common posterior dislocation of elbow.
Perched thus is intermediate stage and sometimes cases present with this stage.
Apart from this the ' perched' deformity is related to facet joints of vertebrae. Unilatwral or bilateral perched facet joints may occasionally present in clinical scenario.
