Table 4.3: Pelvic fractures

DisorderWhole person impairment
1. Non-displaced, healed fractures0
2. Fractures of the pelvic bones (including sacrum) 
    i. maximum residual displacement <1cm2
    ii. maximum residual displacement 1 to 2cm5
    iii. maximum residual displacement >2cm8
    iv. bilateral pubic rami fractures, as determined by the most displaced fragment: 
        a. maximum residual displacement ≥2cm5
        b. maximum residual displacement >2cm8
3. Traumatic separation of the pubic symphysis 
    i. <1cm5
    ii. 1 to 2cm8
    iii. >2cm12
    iv. internal fixation/ankylosis5
4. Sacro-lliac joint dislocations or fracture dislocations 
    i. maximum residual displacement ≥1cm8
    ii. maximum residual displacement>1cm12
    iii. internal fixation/ankylosis5
5a. If two out of three joints are internally fixed/ankylosed8
5b. If all three joints are internally fixed/ankylosed10
6. Fractures of the coccyx 
    i. healed, (and truly) displaced fracture1
    ii. excision of the coccyx5
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%.
