Study Design.

A retrospective study of 24 sacroiliac joint computed tomographic (CT) scans of patients with persistent donor site pain.

Objective.

To illustrate the computed tomographic findings of sacroiliac joints in patients who underwent posterior iliac bone graft harvesting with subsequent persistent donor site pain.

Summary of Background Data.

In a previous study the posterior iliac bone harvesting site was divided into three zones. Zone 1 carried no risk of violation of the synovial part of the sacroiliac joint. In Zones 2 and 3 there was a potential risk of violation to the synovial part of the sacroiliac joint. There is no study in the literature on the effect of violating the different parts of the sacroiliac joint during posterior iliac bone graft harvesting.

Methods.

Computed tomographic scans of the sacroiliac joints of 22 patients with persistent pain in 24 sacroiliac joints after posterior iliac bone graft harvesting were …
