clavicle
Robinson Risk Score for calculation of nonunion risk for displaced midshaft clavicle fractures. Needs 3 inputs:
- Smoker (yes/no)
- Comminution - i.e. presence of 3 or more fracture fragments (yes/no)
- Absolute displacement (mm)
Logit(p) = -5.616 + (1.324 x [1 if smoker or 0 if nonsmoker]) + (0.561 x [1 if comminuted fracture or 0 if noncomminuted fracture]) + (0.153 x
absolute fracture displacement in millimeters).Percentage probability of nonunion = exp(logit[p])/(1 + exp[logit(p)]) x 100.
