    Study Notes

    Skin Grafts and Flaps

    • Skin graft: a nonvascular skin transfer, taking skin from one part of the body and using it in a different area
    • Flap: a portion of skin and/or subcutaneous tissue and muscle, rearranging the skin to fill a hole

    Graft vs. Flap

    • Graft: does not maintain original blood supply
    • Flap: maintains original blood supply

    Classifications of Flaps

    • According to donor site:
      • Local
      • Distant
    • According to tissue transferred:
      • Skin
      • Subcutaneous tissue
      • Fascia
      • Muscle

    Indications for Skin Grafts

    • Temporary cover:
      • To close an open wound
      • To prevent infection
      • To hasten initial healing
      • To prevent exposure of underlying structures
    • Permanent cover:
      • To provide permanent skin replacement
      • To resurface areas of scarring or contractures

    Types of Skin Grafts

    • According to donor site:
      • Autograft: skin transferred from one area of the body to another
      • Allograft (homograft): skin from another human (possibly a cadaver), providing temporary cover
      • Xenograft (heterograft): animal skin (e.g., pig skin), providing temporary cover
    • According to thickness:
      • Split-thickness skin graft (STSG): includes epidermis and part of the dermis
      • Full-thickness skin graft (FTSG): includes epidermis and entire dermis

    Donor Sites for Skin Grafts

    • Ideal donor site provides skin identical to the surrounding skin
    • Skin varies dramatically from one anatomic site to another in terms of:
      • Color
      • Thickness
      • Hair
      • Texture

    Healing of Skin Grafts

    • Phase 1: serum imbibition (diffusion of nutrition from the recipient bed)
    • Phase 2: revascularization (new capillaries start invading the skin graft)
    • Phase 3: organization (collagen linkages are made between the wound bed and the graft)

    Requirements for Graft Survival

    • Well-vascularized bed
    • Immobilization of graft and recipient
    • Low bacterial count at the site

    Factors Affecting Wound Healing

    • Age
    • Infection
    • Nutritional factors
    • Vitamins (C, A, E, B, Thiamine) and trace elements (iron, zinc, copper, manganese, calcium, magnesium)
    • Oxygen
    • Diseases causing impaired wound healing (diabetes, chronic renal failure, liver failure, malignancy, steroids, chemotherapy, radiation)
    • Drugs altering immune system

    Physical Therapy Treatment for Skin Grafting Patients

    • Pre-grafting stage:
      • Maintenance of a good airway
      • Reduction of edema
      • Prevention of structural damage
      • Prevention of contracture and deformity
      • Maintenance of ROM and strength
    • Grafting and post-grafting stage:
      • Prevention of structural damage
      • Reduction of edema
      • Prevention of infection
      • Prevention of scar formation
      • Increase of ROM and strength
      • Improvement of functional activities and walking
