Q

What is arthrodesis?

A

The surgical fusion of a joint in a position of function

17
Q

Arthrodesis is good at relieving pain. What are the downsides to this approach?

A

Function may be limited, and there may be increased pressure on surrounding joints which may lead to arthritic change

18
Q

Arthrodesis is a good option for OA where?

A

Ankle, wrist, 1st MTP of foot

19
Q

What is an osteotomy? What can it be used for?

A

The surgical realignment of bone which can be used to correct deformities or redistribute pressure across a joint

20
Q

Osteotomy is useful for arthritis where?

A

Early arthritis in the hip/knee
