Open Pelvic fractures – Classification

General principles and classification of open fractures have been discussed earlier. The Gustillo-Anderson classification commonly used for the long bone fractures might not be suitable for open pelvic fractures.

Jones-Powell classification

It is based on the mechanical stability of the pelvic ring and the potential contamination of the open wound.

Class 1 – Stable pelvic ring

Class 2 – Pelvic ring unstable (no rectal or perineal wound)

Class 3 – Pelvic ring unstable (rectal or perineal wound)


Class 1 – 0%
Class 2 – 24%
Class 3 – 38%

Faringer Classification

It correlates the site of the open wound and the need for colostomy.

faringer classification
Hermans, E., Edwards, M.J.R., Goslings, J.C. et al. Open pelvic fracture: the killing fracture?. J Orthop Surg Res 13, 83 (2018).

Zone I: perineum, anterior pubis, medial buttock, posterior sacrum)

Zone II: medial thigh, groin crease

Zone III: posterolateral buttock, iliac crest

Faringer proposed that:

1. Most patients with zone I injuries should undergo fecal diversion.

2. Patients with deep lacerations over the posterior buttock should also be considered candidates for diversion, particularly when prolonged bed rest or fecal incontinence is anticipated.

3. Patients with zone II wounds into the subcutaneous fat located in the anterior groin crease or the medial thigh may selectively require fecal diversion.

4. Fecal diversion is rarely required for wounds in zone III.
