Risk factors for subsidence of titanium mesh cage following single-level anterior cervical corpectomy and fusion.


ABSTRACT: BACKGROUND:To clarify the risk factors for subsidence of titanium mesh cage (TMC) following single-level anterior cervical corpectomy and fusion (ACCF) to reduce subsidence. METHODS:The present retrospective cohort study included 73 consecutive patients who underwent single-level ACCF. Patients were divided into subsidence (n?=?31) and non-subsidence groups (n?=?42). Medical records and radiological parameters such as age, sex, operation level, segmental angle (SA), cervical sagittal angle (CSA), height of anterior (HAE) and posterior endplate (HPE), ratio of anterior (RAE) and posterior endplate (RPE), the alignment of TMC, the global cervical Hounsfield Units (HU) were analyzed. Clinical results were evaluated using the Japanese Orthopedic Association (JOA) scoring system and the Visual Analog Scale (VAS). RESULTS:Subsidence occurred in 31 of 73 (42.5%) patients. Comparison between the groups showed significant differences in the value of RAE, the alignment of TMC and the global cervical HU value (p??1.18 (OR?=?6.116, 95%CI?=?1.613-23.192, p?=?0.008), alignment of TMC?>?3° (OR?=?5.355, 95%CI?=?1.474-19.454, p?=?0.011) and the global cervical HU value
