Posterior Stabilization of Unstable Sacroiliac Injuries With the Texas Scottish Rite Hospital Spinal Instrumentation

This article describes a new alternative technique for stabilization of unstable sacroiliac injuries using the Texas Scottish Rite Hospital (TSRH) instrumentation. The TSRH instrumentation was applied in 14 consecutive patients with unstable posterior pelvic ring disruptions. All patients underwent follow-up for an average of 29 months. Clinical results, using the rating system of d'Aubigne, were good in 9 and satisfactory in 5 patients. No pressure sores, infection, significant loss of correction, or hardware failures were observed postoperatively. The use of the TSRH instrumentation for stabilization of sacroiliac injuries offered sufficient stabilization of the posterior pelvic ring and permitted early mobilization without loss of correction.
