procedure?
Answer: Closing base wedge osteotomy
●● Which is the most common hyperdactyly variant?
Answer: Postaxial
●● What is the most common cause of a keloid formation
postoperativelly?
Answer: High tension
-treat with intralesional steroid injection, improves pain and itching

Answer: When a nerve is crushed or cut and the distal position of the
axon degenerates

has potential to regeneration with or without re-approximation of the
endoneurium
,Answer: F - must be reapproximated otherwise will not regenerate
