5 Techniques for Accurate Wound Measurements
March 18, 2014

The measurement of a wound, and the plotting of its size over time, is the only estimate that can be used to accurately predict wound healing. This includes such variables as wound exudate, the presence of necrotic tissue, slough and granulation tissue, as well as undermining and tunneling.
Creative Closure of Tunneling and Undermining Wounds with Negative Pressure Wound Therapy

By Beth Hawkins Bradley RN, MN, CWON
Wounds treated with negative pressure wound therapy (NPWT) are not often straightforward. They occur in interesting places, have anything from slough to hardware visible in the bases, and have nooks and crannies that are not visible to the clinicians peering into the wound. A gentle probe is necessary during wound assessment to identify tunnels and undermined areas. I prefer to gently probe first with my gloved finger (I have small hands) because I can identify hidden structures and other oddities. Then I will use a swab to measure how far the tunnel or undermining extends. Once hidden dead spaces have been identified, clinicians can select the best strategy to bring them to closure. Herein are several techniques employed by clinicians to close undermined and tunneled areas.
How to Assess Wounds for Tunneling and Undermining

As part of a thorough wound assessment, in addition to noting location and measuring size, the entire wound bed should be probed for the presence of tunneling and/or undermining. If you are unsure what tunneling and undermining are and how to recognize these phenomena, here's an explanation of these terms and how to assess wounds for their presence.
Tunneling Wound Assessment and Treatment
November 15, 2017
By the WoundSource Editors
Perhaps the most difficult type of wound for health care professionals to treat is a tunneling wound. Tunneling wounds are named for the channels which extend from the wound, into or through subcutaneous tissue or muscle. These tunnels sometimes take twists or turns that can make wound care complicated. Tunneling is often the result of infection, previous abscess formation, sedentary lifestyle, previous surgery at the site, trauma to the wound or surrounding tissue, or the impact of pressure and shear forces upon many tissue layers causing a “sinkhole-like” defect on the skin. Tunneling wounds need careful wound assessment and management.
