A complex wound may follow trauma, infection, pressure, a failed closure or a previous operation. The surface opening is only one part of the assessment; the condition of the tissue underneath determines what can heal.
The goals are to control infection, preserve or restore blood supply, protect vital structures and create coverage that can heal and tolerate movement.
Why a wound may not heal
- Infection or unhealthy tissue at the wound bed
- Exposed bone, tendon, joint or hardware
- Loss of skin and soft tissue after trauma
- Poor blood flow, smoking or medical conditions that affect healing
- Tension, movement or a deeper problem that has not been addressed
How the wound is evaluated
Assessment considers the size and depth of the wound, the tissue that is exposed, blood flow, sensation, tendon and joint function, infection and the health factors that affect healing. Imaging or laboratory tests may be used when they answer a specific question.
Coverage options
A skin graft can cover a healthy wound bed that can support it. A flap brings its own blood supply and may be needed when bone, tendon, joint or hardware is exposed. Coverage can be local, regional or free depending on the defect and the available tissue.
The simplest reliable coverage is generally preferred, but the wound and function determine what is possible. Therapy and protection are part of the reconstruction rather than an afterthought.
Recovery
Complex wounds often heal over weeks to months and may need more than one stage. The timeline depends on infection, reconstruction, tissue healing and the need to restore motion without disturbing coverage.

Frequently asked questions
Is a skin graft always enough for a hand wound?
No. A graft needs a healthy wound bed. If bone, tendon, joint or hardware is exposed, a flap with its own blood supply may be needed.
Why can’t a wound simply be stitched closed?
Closing a wound under tension or over unhealthy tissue can cause it to open again or trap infection. The reason the wound is open must be addressed first.
