Repeated traction of periosteum causes tearing injury of periosteum, local vasodilation and congestion, and local edema, which leads to aseptic inflammation of periosteum.

The time of debridement after trauma is not limited, but the treatment after debridement is different. If it's just trauma, go to the hospital for debridement in time, and local suture may be performed, which will shorten the wound healing time. For example, the debridement time is delayed, and the wound healing time may be prolonged if it is not sutured after treatment.

Matters needing attention in debridement

According to different levels and structures, different debridement strategies should be adopted. For example, in the epidermal layer, conservative debridement strategy should be adopted as far as possible to prevent insufficient soft tissue coverage on the surface. In some deep muscles and fascia, this layer can adopt a more thorough debridement strategy, and once the contaminated or inactivated tissue is suspected, it should be completely removed.

Some important structures, such as blood vessels, nerves, muscles, tendons, etc., should be debrided to a limited extent and the useful parts should be preserved as much as possible. The debridement process of hand trauma needs long-term exercise to make a more accurate judgment.
