To examine, through retrospective and prospective chart review, the difference in pain and mobility, pre and post treatment, as assessed by the patient's completion of the VAS pain scale and Roland Morris Disability Questionnaire (RMDQ).

CT fluoroscopy guidance during percutaneous sacroplasty is an effective treatment for sacro-iliac insufficiency fractures resulting in rapid reduction of pain and improved mobility in patients. This can be effectively assessed using the VAS pain scale and RMDQ both pre and post procedure.

The purpose of the study is to report the use of CT fluoroscopy guidance during the performance of percutaneous sacroplasty. In addition, clinical results will be reported with the Roland Morris Disability Questionnaire(RMDQ)pre and post procedure, demonstrating the utility of the RMDQ in assessing improvement in patients pain, mobility and ability to perform activities of daily living.

Inclusion Criteria:

• greater than 18 years of age and treated with or about to be treated with percutaneous CT fluoro-guided sacroplasty, regardless of gender or ethnicity.

Exclusion Criteria:

• less than 18 years old
• pregnancy
• inability to complete forms and surveys

Patient's with pain and decreased mobility as a result of sacro-iliac insufficiency fracture(s).
