Purpose
Sacral resection is a potentially curative procedure for patients with sacral tumours,
both malignant tumours and aggressive benign neoplasms.
Lumbo-pelvic fixation is performed to restore axial and pelvic stability where resection involves more than 50% of the sacroiliac joint,
usually with a combination of metalwork and fibular strut grafts.
(1,
2) An example of this construct is shown in Figure 1.
Lumbo-pelvic stabilisation is technically challenging due to the high mechanical demand in this region.
Although 24 cases of this surgery have been reported in the surgical literature,
these focus on surgical technique and list complications.
The purpose of this study is to characterise for the first time,
the imaging features of complications of sacrectomy with lumbo-pelvic fixation.
