1. Humerus, Elbow and Forearm Flashcards
Most common elbow fracture in Adults
Radial head
Most common elbow fracture in kids
Supracondylar
What fat pad is specific in occult fracture?
posterio fat pad.
Capitellum fractrues association
posterior dislocation
forearms fractures = pretzel/ring types = they are often
two fractures or a fracture + dislocation
Fx
Proximal ulna + anteiror dislocation of the radial head
Dislocation of the radial head follows the angulation of the Ulnar Fx.
Monteggia Fracture (MU - GR)
Monteggia fracture occurs in what population?
children
Moneggia - minors
Fx
Radial SHAFT + anterior dislocation of the ulna at the DIstal radioulnar joint (DRUJ).
Galeazzi Fracture (MU - GR)
Fx
Radial HEAD + Anterior dislocation of the DRUJ
Essex-Lopresti
Most common cause of Cubital Tunnel Syndrome
accessory anconeus
Seen in tennis playetrs
Repetitive extension = extensor tendon injury (ECRB) = radial collateral ligament complex tears due to Varus stress =
Lateral Epicondylitis (more common than medial)
Golfers + repetitive flexion + common flexor tendon and ulnar nerve enlargement =
MEdial epicondylitis
THROWERS hurt this ligament =
Ulnar collateral ligament (attached to sublime tubercle)
Most important bundle in Partial Medial Ulnar Collateral Ligament Tear
ANTERIOR BUNDLE
Partial Medial Ulnar Collateral Ligament Tear
Partial MEdial ulnar collateral ligament tear
T sign
a repetitive chronic injury to the medial epicondyle
Stress fracture/Avulsion/Delayed clossure = medial epicondylar apophysis
Little Leaguer Elbow
Usually associated with UCL injury
Valgus overload syndrome
TRIAD
lateral compression
medial tension
posterior sheer
This is a classic look for cat-scratch disease.
Epitrochlear Lymphadenopathy
Partial biceps tears association
Bicipitoradial bursitis
painful mass in the antecubital fossa (rolled up muscle) - with the classic history of “trying to impress the girl in the pink spandex sports bra with my deadlift.”
Biceps tear
Popeye deformity
Injury to the bicep associations
median nerve
LEAST common tendon in the body to rupture
Tricep tensdon
When I say Tricep Rupture, think of?
salter harris II fractures of the olecranon
second most common joint dislocated in the adult
Elbow Dislocation
Associated Fx in Elbow dislocation
Radial head + Coronoid process
Instability in the elbow =
Posterior Rotary Instability
Patern of Posterior Rotary Instability
Start = Posterio lateral corner + tearing of teh lateral UCL
