Vertical

Question 32

what suture pattern is this

Answer 32

Interrupted horizontal mattress-everting

Question 33

Which suture pattern provides the best tension relief and why

Answer 33

Interrupted horizontal mattress- everting because of geometry has tendency to reduce blood supply to wound edges
