Multivariate predictors of failure after flap coverage of pressure ulcers.

Background: Pressure ulcers are estimated to be present in more than one-third of patients with spinal cord injury. The rate of recurrence after flap surgery over last 50 years has ranged between 3 and 82 percent, with no trend toward improvement. This study seeks to identify and evaluate patient and operative characteristics associated with flap dehiscence and ulcer recurrence.
