Mirel's score
From Wikipedia, the free encyclopedia
Mirels' score is a tool useful in the management of bone tumors, by identifying those patients who would benefit from prophylactic fixation if they have a high enough risk of pathological fracture.
Scoring
A score of 1 to 3 is given for four criteria and summed together. A score greater than 8 suggests prophylactic internal fixation prior to irradiation.

| 1 | 2 | 3 | |
| Site | Upper limb | Lower limb | Peritrochanteric |
| Pain | Mild | Moderate | Functional |
