Long-term results of anterior cervical corpectomy and fusion with nano-hydroxyapatite/polyamide 66 strut for cervical spondylotic myelopathy
To assess the long-term clinical and radiographic outcomes of anterior cervical corpectomy and fusion (ACCF) with a neotype nano-hydroxyapatite/polyamide 66 (n-HA/PA66) strut in the treatment of cervical spondylotic myelopathy (CSM). Fifty patients with CSM who underwent 1- or 2-level ACCF with n-HA/PA66 struts were retrospectively investigated. With a mean follow-up of 79.6 months, the overall...
متن کاملFresh frozen cortical strut allograft in two-level anterior cervical corpectomy and fusion
Anterior cervical corpectomy and fusion (ACCF) is one of the main surgical strategies for the management of multilevel cervical spondylotic myelopathy (MCSM). High complication rates of graft bone fracture, resorption, displacement, and fusion collapse or pseudarthrosis have been previously reported. The strategies to prevent the aforementioned complications include using fresh frozen cortical ...
متن کاملSagittal Alignment of a Strut Graft Affects Graft Subsidence and Clinical Outcomes of Anterior Cervical Corpectomy and Fusion
Study Design Retrospective study. Purpose The purpose of this study was to investigate the influence of sagittal alignment of the strut graft on graft subsidence and clinical outcomes after anterior cervical corpectomy and fusion (ACCF). Overview of Literature ACCF is a common technique for the treatment of various cervical pathologies. Although graft subsidence sometimes occurs after ACCF,...
متن کاملPreventing Construct Subsidence Following Cervical Corpectomy: The Bump-stop Technique
Cervical corpectomy is a viable technique for the treatment of multilevel cervical spine pathology. Despite multiple advances in both surgical technique and implant technology, the rate of construct subsidence can range from 6% for single-level procedures to 71% for multilevel procedures. In this technical note, we describe a novel technique, the bump-stop technique, for cervical corpectomy. Th...
