Burn Reconstruction: after the wound heals
Burn reconstruction addresses what happens after the initial wound closes — scar contractures that limit movement, unstable or painful scars, and cosmetic concerns. Timing matters: some releases are done early to prevent a contracture worsening in a growing child or across a joint, while others benefit from waiting for scar maturation.
Contractures: why burn scars restrict movement
As a burn heals, particularly one that crosses a joint or area of movement, the scar tissue that forms can tighten and shorten over time, pulling the skin and underlying tissue into a fixed, restricted position — a contracture. This happens because scar tissue is less elastic than normal skin and naturally contracts as it matures, and it's a particular concern over joints (elbows, knees, neck, hands) where restricted movement has a direct functional impact, and in growing children, where a tight scar can increasingly limit movement as the child grows around it.
Reconstructive options: grafts, flaps, and newer techniques
Treatment depends on the contracture's severity and location. Simpler releases may use a skin graft to resurface the area after releasing the tight band. More complex contractures, especially over joints or where deeper tissue is involved, often need a flap (tissue moved with its own blood supply, discussed further on the flap surgery page) for a more durable, functional result. Techniques like Z-plasty (a specific incision pattern that redistributes tension across a scar) are frequently used to lengthen a tight scar band without needing to import tissue from elsewhere.
Timing surgery: early release vs waiting for maturation
This is a genuine judgement call that depends on the situation. A contracture that is actively restricting a joint's function, or worsening in a growing child, often needs earlier surgical release rather than waiting, since delay allows the restriction to worsen and can affect the joint itself over time. Purely cosmetic scar revision, on the other hand, generally benefits from waiting 12-18 months for the scar to fully mature and soften, since scars continue to improve somewhat on their own during this period and surgery timed too early may be treating a scar that would have partially improved regardless.
Frequently asked questions
How long after a burn can reconstruction be done?
It depends on the problem — a contracture threatening joint function may need earlier release, while scar revision for appearance usually waits 12-18 months for the scar to mature and soften.
Can burn scars be completely removed?
No treatment erases a burn scar entirely, but contracture release restores movement, and scar-directed treatment (surgical and non-surgical) meaningfully improves both function and appearance.
