Methods and Materials
We performed a retrospective review of our orthopaedic oncology database in order to identify all patients with sacral neoplasia who had undergone total or partial sacrectomy requiring lumbo-pelvic reconstruction.
Postoperative imaging was jointly assessed by two experienced musculoskeletal radiologists,
with consensus decision when there was a difference in interpretation.
MR imaging was performed on a 1.0 Tesla MR scanner and CT imaging was performed on a 4 slice scanner.
Standard radiographic projections of the lumbar spine and pelvis were obtained as clinically indicated.
The size of the tumour on preoperative imaging,
and the components of sacral reconstruction on the subsequent postoperative study were documented.
The signal characteristics and morphology of the pelvic musculature and evidence of local recurrence or lymphadenopathy were assessed on postoperative MR studies.
Integrity of the fibula graft and metalwork were recorded.
Other complications or imaging features were separately noted.
