摘　　要：BACKGROUND Posterior atlantoaxial dislocation(PAD)is a rare type of upper cervical spine disease.We sought to describe a unreported case of old PAD with os odontoideum(OO)and atlas hypoplasia(AH)and our unique treatment approach consisting of C1 single door laminoplasty with C1-3 posterior fixation and fusion.CASE SUMMARY A 70-year-old male patient who suffered from progressive aggravating numbness and limb weakness for 4 years without trauma,was diagnosed with old PAD with OO and AH.The patient underwent closed reduction and C1 single door laminoplasty with C1-3 posterior fixation and fusion instead of C1 laminectomy with occipitocervical fusion.During the 3-year follow-up,he was able to walk by himself instead of using a wheelchair and with a±25°range of head rotation as well as a±10°range of flexion-extension.Three-year follow-up images showed satisfactory reduction and fusion.CONCLUSION C1 single door laminoplasty with cervical fusion in PAD combined with spinal cord compression could be a suitable and effective surgical option.Compared with laminectomy and occipitocervical fusion,it retains more cervical range of motion,has a smaller incision and provides an adequate bone grafting space for atlantoaxial fusion.
