Chronic Osteomyelitis and 5 cm Bone Defect Treated with Masquelet Technique Followed by Ilizarov

This case is an example of acute hematogenous osteomyelitis that progressed to chronic osteomyelitis due to a significant necrotic bone segment (secondary to a subperiosteal collection of pus). The patient was treated with multiple episodes of irrigation and debridement as well as local control via antibiotic cement beads. The Masquelet technique was then used to address the segmental bone loss. This was subsequently complicated by a pathologic stress fracture through the healed graft leading to a hypertrophic nonunion. The hypertrophic nonunion and deformity were treated via distraction with an external fixator.
