The coccygeal pressure ulcer-does coccygectomy prevent recurrence?

This is a retrospective, non-randomized cohort study, with data collected during the regular annual visits between 2001 and 2019.

The aim of this study was to evaluate the efficacy of coccygectomy for coccygeal pressure ulcers in individuals with paraplegia due to spinal cord injury or other neurological causes and to evaluate its role in the prophylaxis of ulcer recurrence.

This study included inpatients and outpatients with a coccygeal pressure ulcer who were treated surgically at our Institution REHAB Basel and were followed with regular annual check-ups.

Individuals with category 3 or 4 acute or chronic coccygeal pressure ulcer (classification according European Pressure Ulcer Advisory Panel (EPUAP)) received coccygectomy in addition to rotation flap surgery. The operative care was provided exclusively by the head of the plastic surgery department at REHAB Basel. Standardized follow-up treatment was carried out according to the "Basel Decubitus Concept" and thus allowed continuous and usually lifelong, regular follow-up care.

Forty-nine individuals underwent coccygectomy from 2001 to 2019 due to coccygeal category 3 or 4 pressure ulcers. The observation period was between 1.5 and 18.3 years. In 86% of the individuals, no relapse occurred during the first year. Over the next 5 years 78% remained relapse free.

In coccygeal pressure ulcer category 3 or 4, coccygectomy, in addition to sufficient rotation flap surgery, is a suitable method for recurrence prevention of pressure ulcer in this anatomic area.
