Reconstructive Surgery of Pressure Injuries in Spinal Cord Injury/Disorder Patients: Retrospective Observational Study and Proposal of an Algorithm for the Flap Choice.

Pressure injuries (PIs) are a common complication in patients with spinal cord injury/disorder (SCI/D), and deep PIs require surgical treatment consisting of wide debridement and adequate reconstruction. We conducted a retrospective observational study at a tertiary rehabilitation hospital for SCI/D in Italy with the aim of describing the incidence and associated risk factors of postoperative complications in individuals with SCI/D presenting with chronic deep PIs, treated with a specific flap selection algorithm based on the site of the defect, the presence of scars from previous surgeries, and the need to spare reconstructive options for possible future recurrences. Medical records of surgical procedures performed on SCI/D patients with fourth-degree PIs, according to NPUAP classification (National Pressure Ulcer Advisory Panel), between July 2011 and January 2018 were reviewed. A total of 434 surgical procedures for fourth-degree PIs in 375 SCI/D patients were analyzed. After a mean follow-up of 21 months (range 12-36), 59 PIs (13.6%) had minor complications, and 17 (3.9%) had major complications requiring reoperation. The sacral site and muscular and musculocutaneous flaps were significant risk factors for postoperative complications. Six patients (1.4%) had a recurrence. The choice of flap correlates with the outcome of decubitus reconstruction. Therefore, reconstructive planning should be based on established principles.
