Comparison of structural allograft and traditional autograft technique in occipitocervical fusion: radiological and clinical outcomes from a single institution

摘要: OBJECT The authors’ objectives were to compare the rate of fusion after occipitoatlantoaxial arthrodesis using structural allograft with from autograft, evaluate correction radiographic parameters, and describe symptom relief each graft technique. METHODS authors assessed radiological at 6 12 months surgery obtained measurements C1–2 C2–7 lordotic angles, sagittal vertical alignments, posterior occipitocervical angles preoperative, postoperative, final follow-up examinations. Demographic data, intraoperative details, adverse events, functional outcomes collected hospitalization records. Radiological was defined as presence bone trabeculation no movement between occiput or C-2 on routine flexion-extension cervical radiographs. Radiographic lateral standing radiographs patients in neutral position. RESULTS At Universit...
