The successful treatment of a Gustilo-Anderson type IIIc distal leg injury with a large bone defect in elderly patient with severe osteoporosis: a case report.

backgroundGustilo-Anderson type IIIc tibial open fracture with large bone defects in elderly patients with severe osteoporosis is a rare injury that may be a challenging clinical scenario. CASE PRESENTATION: This study presents the case of a 68-year-old Japanese man who sustained a Gustilo-Anderson type IIIc open tibial fracture with a large bone defect. The patient had severe osteoporosis and the bone was contaminated; therefore, we determined that the bone could not be returned to the tibia. The patient underwent acute limb shortening and gradual lengthening with an Ilizarov external fixator combined with low-intensity pulsed ultrasound and teriparatide administration for limb reconstruction, which allowed immediate full weight-bearing capacity. The fixator was removed at 12 months postoperatively, and by this time, the fracture had completely healed. At the most recent 5-year follow-up after the injury, the patient reported full weight-bearing capacity without walking aids and had full knee and ankle range of motion.

conclusionsTo the best of our knowledge, this is the first study to report the use of combined Ilizarov technique, low-intensity pulsed ultrasound, and teriparatide for limb reconstruction of Gustilo-Anderson type IIIc open tibial fractures with large bone defects in elderly patients with severe osteoporosis.
