Table 4.3: Pelvic fractures
| Disorder | Whole person impairment |
|---|---|
| 1. Non-displaced, healed fractures | 0 |
| 2. Fractures of the pelvic bones (including sacrum) | |
| i. maximum residual displacement <1cm | 2 |
| ii. maximum residual displacement 1 to 2cm | 5 |
| iii. maximum residual displacement >2cm | 8 |
| iv. bilateral pubic rami fractures, as determined by the most displaced fragment: | |
| a. maximum residual displacement ≥2cm | 5 |
| b. maximum residual displacement >2cm | 8 |
| 3. Traumatic separation of the pubic symphysis | |
| i. <1cm | 5 |
| ii. 1 to 2cm | 8 |
| iii. >2cm | 12 |
| iv. internal fixation/ankylosis | 5 |
| 4. Sacro-lliac joint dislocations or fracture dislocations | |
| i. maximum residual displacement ≥1cm | 8 |
| ii. maximum residual displacement>1cm | 12 |
| iii. internal fixation/ankylosis | 5 |
| 5a. If two out of three joints are internally fixed/ankylosed | 8 |
| 5b. If all three joints are internally fixed/ankylosed | 10 |
| 6. Fractures of the coccyx | |
| i. healed, (and truly) displaced fracture | 1 |
| ii. excision of the coccyx | 5 |
| 7. Fractures of the acetabulum: Evaluate based on restricted range of hip motion |
The rating of WPI is evaluated based on radiological appearance at maximum medical improvement, whether or not surgery has been performed. Multiple injuries of the pelvis should be assessed separately and combined, with the maximum WPI for pelvic fractures being 20%.
