Tomita et al develop a grading scheme for determining the extent of an osteosarcoma arising within the sacrum. This can help determine the optimum surgical management for the patient.
Extent of the Osteosarcoma
Grade
localized to S4 and/or S5 (below S3)
I
localized to S3, S4 and/or S5 (below S2)
II
involvement of S1
III
extension into lumbar spine
IV
extension into sacroiliac joint
IV
extension into intrapelvic organs
IV
where:
• Involvement of S2 appears to be a Grade III lesion.
Grade
Surgical Management
I
low sacral amputation
II
high sacral amputation
III
total sacrectomy
IV
extended sacrectomy
