Ligamentous constraints include the annular ligament
and radial (lateral) collateral ligaments which provide stability to the proximal radiocapitellar and proximal radioulnar joints and to resist varus stress.
Notwithstanding an absence of ligamentous laxity, pain was elicited during palpation of the ulnar collateral ligament and annular ligament
Trachea was not damaged much, there was tear in annular ligament
and mucosa of trachea ventrally (Fig.
The anterolateral dislocation is more commonly associated with annular ligament
injuries, but the anteromedial dislocation is rare.
The LUCL complex originates on the lateral epicondyle with fibers fanning out into the annular ligament
while other fibers, as Sanderhoff et al describe, pass through the annular ligament
and insert on the crest of the ulna.
The three main ones are the ulnar collateral ligament, radial collateral ligament, and annular ligament
Thus a rupture of the superior peroneal retinaculum can be considered as a annular ligament
or pulley lesion.
At this level, both flexor tendons are palmarly surrounded by the inelastic, strong, transverse fibers of the palmar annular ligament
, which in association with the proximal scutum (i.
First osteotomy of the ulna at fracture site, correction of mal-alignment, maintaining ulnar length, open reduction of radial head, annular ligament
reconstruction with triceps fascial loop and transcapitellar K-wire fixation of radial head.
