WHERE are heterotopic ossifications most commonly found/occur?
the hip; second most common location is the elbow
WHEN do heterotopic ossifications typically occur?
after surgery or trauma (traumas like fractures, dislocations, and operative procedures, elbow burns or elbow replacements)
heterotopic ossifications in hip are typically treated in how many Gy? and how many fractions?
6-8 Gy in 1 fraction; low doses of radiation
heterotopic ossification radiation occurs ______ or ______
pre or post-operatively
if heterotopic ossification is getting treated pre-op timing must be within ___hrs. If getting treated post-op timing must be within ___ hrs
pre-op within 24 hrs, post-op within 72 hrs
pre-op radiation for heterotopic ossifications is preferred, why?
patient won’t be in as much pain before operation than they would be after
_____ are a benign excessive growth of scar tissue
keloids - due to an excess amount of collagen in skin during healing process
how do we treat keloids most effectively? ___ followed by ____
surgery followed by radiation
