Wound classification and wound closure analysis

Wound classification helps clinicians and product manufacturers accomplish a number of goals:

  • Identify the relative size of distinct patient populations
  • Characterize the types and severity of problems represented in each category
  • Establish and standardize methods for treating wounds by category

The different options for segmenting the population of wound patients are based on morphology, severity, etiology and, for surgical wounds in particular, the classification of surgical wounds by degree of contamination or infection.

Morphology, with unique characteristics for each being tissue characteristics, etiology, and prognosis for healing:

  • Partial thickness
  • Deep partial thickness
  • Full thickness
  • Underlying tissue damage

Severity, with unique characteristics for each being tissue characteristics and etiology:

  • Tidy wound
  • Untidy wound
  • Wound with tissue loss
  • Infected wound


  • Surgical
  • Traumatic
  • Burns
  • Chronic
  • Carcinoma

Lastly, surgical wounds may be characterized by level of contamination:

  • Class I: clean wound
  • Class II: clean/contaminated wound
  • Class III: contaminated wound
  • Class IV: dirty or infected wound

Wound types are the focus of technologies to close, seal, initiate hemostasis and other functions necessary to result in optimized wound healing.  Traditional technologies of tapes and sutures have been augmented by an incredible array of new products spanning devices, biomaterials, biotechs and others that minimize blood loss, reduce the risk of infection, minimize scarring, reduce cost or otherwise accelerate the process of natural wound healing.

Wound closure and healing is the subject of the worldwide report, “Worldwide Market for Surgical Sealants, Glues, Wound Closure and Anti-Adhesion, 2012-2017”, Report #S190, from MedMarket Diligence. This report details the complete range of sealants & glues technologies used in traumatic, surgical and other wound closure, including tapes, sutures/staples/mechanical closure, hemostats, fibrin sealants/glues and high-strength medical adhesives and anti-adhesion products.  Comprehensive data is provided on products on the market, in development, current/forecast markets (with global, regional and country-specific breakdowns), companies and opportunities for manufacturers.  (See link for details.)
