The SINS score was published in 20101 and is used as an aid in determining surgical indications for neoplasms of the spine.
| Location | Points |
|---|---|
| Junctional (O-C2; C7-T2; T11-L1; L5-S1) | 3 |
| Mobile spine (C3-6; L2-4) | 2 |
| Semirigid (T3-10) | 1 |
| Rigid (S2-S5) | 0 |
| Mechanical pain | Points |
| Yes | 3 |
| Occasional pain, not mechanical | 1 |
| Pain-free lesion | 0 |
| Bone lesion | Points |
| Lytic | 2 |
| Mixed (lytic/blastic) | 1 |
| Blastic | 0 |
| Radiographic spinal alignment | Points |
| Subluxation/translation present | 4 |
| Deformity (kyphosis / scoliosis) | 2 |
| Normal | 0 |
| Vertebral body collapse | Points |
| Collapse >50% | 3 |
| Collapse <50% | 2 |
| No collapse with >50% vertebral body involvement | 1 |
| None of the above | 0 |
| Posterolateral involvement | Points |
| Bilateral | 3 |
| Unilateral | 1 |
| Neither unilateral nor bilateral | 0 |
The calculated score serves as an aid in determining the surgical indication for the lesion. The following table can be used to interpret the SINS score2:
| SINS Score | Interpretation |
|---|---|
| 0-6 | Stable |
| 7-12 | Potentially unstable |
| 13-18 | Unstable |
