What is a Cavity Wound?

There is a lack of standardised definition for cavity wounds which can prevent the delivery of evidence-based care. Cavity wounds have been defined as ranging from a relatively shallow cavity wound of less than 2cm to wounds that are more than 2cm deep¹, deep wounds that expose underlying structures such as fascia, tendons, muscle and bone², and more recently a wound that extends beneath the dermis³.

The management of cavity wounds frequently pose a number of clinical and practical challenges to healthcare professionals. They often need debridement, in addition to biofilm, infection and exudate management. The hidden nature of some cavities can present practical challenges in terms of visualising and managing the wound bed, and documenting the wound’s condition, and may therefore require adaptation of the approaches used for non-cavity wounds⁴.

Treatment Aims

The aims of treatment for a cavity wound include wound debridement where applicable, maintaining a moist wound environment by ensuring dressing materials are absorbent and conform to the cavity contours, exudate management, periwound skin protection, pain free application and removal and prevention of infection⁵ ⁶ ⁷.
