Elbow stuff

From the Eval book

QuestionAnswer
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
