ANKLE ARTHRITIS Flashcards
for diagnosis?
usually only a plain film radiograph
smaller % of people have ankle arthritis than knee arthritis because?
greater reservoir for chondrocytes
ankle arthritis is predominantly?
post traumatic
glissans principles?
removal of all interposing tissue
accurate and close fitting fusion surfaces
optimal position
maintenance of bony apposition until fusion
essential for success?
comprehensive understanding of the reason for undergoing the surgery
comprehensive biomechanical evaluation-understand the supramalleolar and inframalleolar influencing factors
outline in detail plan for surgery
consider adjuncts for success
transfibular approach is a technique that uses a plate on what side?
lateral plate
this serves as a source for autogenous bone graft?
fibula removal
this type of graft increases triplanar stability of construct-resists rotation/shear forces?
fibula onlay grafting
arthroscopy preserves?
if there is more than 15 degrees varus or valgus, can you do arthroscopy?
periosteum
nope
this type of screw is needed for fixation of an arthrodesis?
compression screw
this type of ankle arthrodesis is not used for primary cases, but for revision cases only, infected joints…ideal for septic fusions?
external fixation
this type of external fixation is ore stable triplanar and you can bare weight in this?
ilizarov ring fixation
major complications of ankle arthroscopy?
degenerative arthritis of adjacent joints
what is a peritalar joint arthritis?
arthritis around the talus (STJ and TN joint)
what does arthroplasty mean?
joint replacement
