Soft Tissue Injury and Healing 3 Flashcards
soft tissue injuries accompanying fxs
periosteal injury
vascular injury
venous injury
arterial injury
nerve injuries
muscle, tendon and lig injuries
periosteal injury
periosteum forms a “sleeve” around the bone
it could tear and compromise blood supply to bone
what usually occurs w/ periosteal injuries
one side remains intact
creating a kind of “hinge” through which there is some physical support and blood supply
vascular injury is an
EMERGENCY
what happens w/ a vascular injury
bleeding and effusion gets trapped b/c they’re being contained by the fascial compartment
pressure builds up and ischemia occurs
what do vascular injuries cause
pain
contractures
severe nerve damage
ex of vascular injury
compartment syndrome = volkmann’s ischemia
what could a venous injury cause
thrombus
may become an embolus and lodge in heart. lungs and cause death
why could venous stasis occur
inactivity
paralysis
tight cast
arterial injury
not common
could occur d/t sudden and severe traction on artery
may develop persistent arterial spasm and create an occlusion
nerve injuries could occur d/t
fx sites
radial N
fx mid shaft or distal humerus
ulnar N
elbow dislocation w/ or w/o fx
common peroneal N
proximal fibula
L5/S1 nerve root
low lumbar/pelvic fxs
