- Discussion:
- can be used for coverage of finger tip injuries the index, long, ring, (and in some cases the little finger);
- can be used in children and young adults (esp. women)
- Advantages:
- more subcutaneous fat available than cross finger flap
- good color and texture match for pulp;
- donor site can be closed primarily (if all three sides of flap are mobilized);
- Technique:
- outline of donor site:
- proximally flap is harvested w/ radial border made along metacarpal-phalangeal flexor crease;
- maximum flap width is about 2 cm;
- consider designing flap to be 50% wider than defect to recreate pulp;
- donor site is closed primarily or alteranatively FTSG is applied to donor site;
- detach at two weeks;
- Complications:
- potential for joint stiffness
- limited size of flap;
- donor site tenderness
