Osteogenesis imperfecta (OI) is a rare disabling genetic connective tissue disorder. General anesthesia in these patients is associated with increased risks. Regional anesthesia is favored wherever feasible, but there are limited reports of use of a sole regional technique in OI in pediatric patients. Moreover, combined spinal–epidural anesthesia has never been described previously. We are reporting the use of combined spinal–epidural anesthesia for a prolonged surgery (multiple osteotomies) of lower limbs in a 10-year-old wheelchair-bound child with OI type III. Preoperative counseling, ultrasonography guidance, titrated local anesthetic dosage, and dexmedetomidine sedation helped establish optimum surgical conditions.
