Post Burn Contractures

The tissue defect in burns is filled by granulation tissue. This consists of mainly blood vessels, inflammatory cells, fibroblasts, and myofibroblasts. This myofibroblasts are responsible for wound contraction. The traction force produced by myofibroblasts used to realign the extra-cellular matrix (collagen). The myofibroblasts production is totally depend on cytokines or growth factors released by platelets and inflammatory cells. Reduced level of cytokines promotes apoptosis of myofibroblasts, which in turn reduces the severity of contraction. This will happen if the wound is closed early. Contraction of the wound is helpful in healing as it reduces the size of the wound.

Types of contractures

  • Intrinsic contracture: When a contracture is directly responsible for the deformity; it is known as intrinsic contracture.
  • Extrinsic contracture: When a contracture band is away from the deformed structure and is indirectly responsible for the deformity; it is known as extrinsic contracture. Examples are ectropion of lower eyelid due to contraction of wound over the cheek, ectropion of the lower lip due to neck contracture.
