one source of elbow instability
ulnar (medial) collateral ligament sprain
what are UCL sprain usually d/t
chronic valgus and ER forces
what causes chronic valgus and ER forces
overhead throwing
tennis serve
volleyball
baseball
if the UCL sprain is traumatic
FOOSH
injury consisting of tensile loading into valgus &/or ER
where does the UCL lie
medial epicondyle to coronoid process and olecranon
UCL is the
primary restraint to valgus force
when is the UCL taught
through entire ROM
where is the main restraint –> UCL
at 90 degrees of elbow flexion
UCL provides resistance to
valgus stress
chief complaint –> elbow instability
pain
pain –> elbow instability
medial elbow
lateral elbow
distally
medial elbow –> pain –> elbow instability
~ 2 cm distal to epicondyle
stresses lax ligament
lateral elbow –> pain –> elbow instability
compression of H/U joint
distally –> pain –> elbow instability
ulnar nerve irritation
history –> elbow instability
macrotrauma
microtrauma
macrotrauma –> history –> elbow instability
FOOSH
microtrauma–> history –> elbow instability
repetitive valgus force
throwing athletes
asymmetries –> elbow instability
increased carrying angle
tenderness to palpation
R –> elbow instability
elbow
shoulder
elbow –> R –> elbow instability
PROM and AROM = WNL
RROM = pain free and strong
arthrokinematics = excessive lateral tilt of ulna
shoulder –> R –> elbow instability
assess ER and IR
GIRD
T –> elbow instability
play
tone
strength
length
play –> T –> elbow instability
WNL
tone –> T –> elbow instability
WNL
may be increased –> muscles crossing medial elbow
