Mobile
soft tissue cover
A stable,
well vascularized, supple soft tissue cover is a prerequisite to functional
recovery. This requires adequate debridement and, if needed, flap cover.
If a flap is required, and particularly if a free flap is required, timing
is critical. The risk of osteomyelitis, wound healing problems, as well
as the length and cost of hospital care are directly related to the interval
of time between injury and flap cover. Definitive wound closure with a
free flap has the lowest complication rate if performed within three days
of injury, and the highest complication rate if performed during the "subacute"
phase, after granulation tissue has formed (Godina). This timing relationship
goes against traditional teachings of delayed primary closure, possibly
because of differences arising from the use or from the need for a flap.
As elsewhere, the "reconstructive ladder" of wound closure is as follows,
and the surgeon should begin at the bottom and consider each rung before
advancing to the next:
Most
Involved
free
flap
distant

regional
flap

and regional flaps from the hand and adjacent fingers are commonly used
for finger and thumb tip amputations, and are discussed below. Commonly
used larger regional flaps from the forearm include to the radial forearm
flap and the posterior interosseous (dorsal forearm) flap. These and other
available flaps make free flap reconstruction less frequently indicated
for upper extremity reconstruction than for lower extremity reconstruction.
When available, single stage flap reconstruction is preferred. Compared
to staged reconstruction such as that involving a pedicled groin flap,
single stage flaps require less immobilization and allow better elevation
of the hand. Every effort should be made to achieve healing as soon as
possible. In the hand, stiffness, difficulty with use and ultimate disability
is directly related to the length of time required for wound healing.
