title: [Bilateral failure of fusion between pedicles and body of C7].
abstract: We expose the case of a 48-year-old woman suffering of a chronic bilateral C7 radiculalgy and bilateral C7 failure of fusion between pedicles and body. According to spine embryogenesis we bring three hypothesis to explain this failure of fusion. Then we show that bilateral C6-C7 foraminal compression can arise from local cervical spine instability due to C7 and disk development abnormalities. The treatment proposed is dissectomy bone graft and anterior osteosynthesis leading to clinical and radiological good results. The patient went back to work after three months.
