UCL | Ulnar Collateral Ligament- 3 bundles:Anterior Transverse, posterior |
Anterior Bundle of UCL | origin:inferior surface of med. epicondyle, i:med, aspect of coronoid process-primary guard against valgus forces-taught through-out ROM |
Transverse Bundle of UCL | o:med epicondyle-I:coronoid process little support to medial elbow |
Posterior Bundle of UCL | O:olecranon process I:coronoid process |
LUCL | Lateral Ulnar collateral ligament O-mid lat. epicondyle I: tubercle of ulna prvides lat support of ulna-disruption of it =rotatory instability of elbow |
RCL | radial collateral ligament thickened area in lat joing capsule betwen lat epicondyle and annular ligament resists varus forces & mainaints close relationship between humeral and radial surfaces |
Annular ligament | encircles radial head fibro-osseous structure that allows int/ext rotation of rad. head on capitellum attach to coronoid process-makes 4/5 circle prevents radious from sliding distally |
ALCL | accessory lateral collateral ligament assists annular ligament & RCL prevents ulna and radial seperation |
Interosseous membrane | fibrous connective tissue fibers run obliquely allows motion but keeps connection and rythme between ulna and radius |
