1
Problem Wounds, Flaps and Grafts
2
Wound care priorities 4 Discover and treat injuries to critical deep structures 4 Cover critical deep structures with skin 4 Prevent infection, suture only when necessary 4 Maintain function unhindered by contracture 4 Cosmesis is a distant fifth priority
3
Problem Closures 4 Important tissues deep to wound must be explored 4 Wound contaminated or skin nonviable 4 Closure under tension or inadequate skin to close 4 Edges uneven or complex shapes
4
Extend wound for exploration, parallel to important deep structures
5
Problem Closures 4 Important tissues deep to wound must be explored 4 Wound contaminated or skin nonviable 4 Closure under tension or inadequate skin to close 4 Edges uneven or complex shapes
6
Debride contaminated sub Q fat and nonviable skin
7
Debride and undermine to give everted closure
8
Defatting flaps improves viability
9
Apical stitch salvages viability
10
V-Y closure for nonviable edge
11
Closing a nonviable flap
12
Problem Closures 4 Important tissues deep to wound must be explored 4 Wound contaminated or skin nonviable 4 Closure under tension or inadequate skin to close 4 Edges uneven or complex shapes
13
Undermining first choice to relieve tension, but leaves dead space
14
Closing dead space prevents fluid collection but adds foreign body
15
Cotton pledgets may help when you must close under tension
16
Closing circular defect
17
V-Y double advancement flap
18
Curvilinear flap
19
Z-plasty changes direction of wound to align with skin tension; use 60 degree angles
20
Donor sites for full thickness grafts
21
Measure site and prepare graft
22
Hold the graft down to the bed
23
Preferred method to bolster graft in place
24
Problem Closures 4 Important tissues deep to wound must be explored 4 Wound contaminated or skin nonviable 4 Closure under tension or inadequate skin to close 4 Edges uneven or complex shapes
25
Avulsion closure: larger bite on flap side prevents override
26
Use apical stitches first on geographic lacerations
27
Apical first for stellate lacerations too
28
Half buried horizontal for edges of differing thickness
29
Fixing Bowser
30
Closing parallel lacerations; where ample skin, could also simply excise island
31
Dermal suture to close laceration within abrasion
32
Moist occlusive dressing leads to more rapid healing of open wounds
