complete tendon laceration only
vascular injury
pallor, low pulse, decreased cap refill
hematoma
bruit
Foreign body evaluation
LOCALIZED pain or tenderness
patient complaint of FO must be heeded
Imaging is best (evaluate depth of wound)
c/i to wound closure
acute wound >6h old (EXCEPT ON FACE) Cannot remove debris active bleeding dead space under closure too much tension on wound
delayed primary closure
