Sagittal Alignment of a Strut Graft Affects Graft Subsidence and Clinical Outcomes of Anterior Cervical Corpectomy and Fusion.

Sagittal Alignment of a Strut Graft Affects Graft Subsidence and Clinical Outcomes of Anterior Cervical Corpectomy and Fusion. Asian Spine J. 2017 Oct;11(5):739-747 Authors: Yamauchi K, Fushimi K, Miyamoto K, Hioki A, Shimizu K, Akiyama H Abstract 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, it is one cause for poor clinical results. Malalignment of the strut graft is probably one of the factors associated with graft subsidence. However, to the best of our knowledge, no prior reports have demonstrated correlations between the alignment of the strut graft and clinical outcomes. Methods: We evaluated 56 patients (33 men and 23 women; mean age, 59 years; range, 33-84 years; 45 with cervical spondylotic myelopathy and 11 with ossification of the posterior longitudinal ligament) who underwent one- or two-level ACCF with an autogenous fibular strut graft and anterior plating. The Japanese Orthopaedic Association (JOA) score recovery ratio for cervical spondylotic myelopathy was used to evaluate clinical outcomes. The JOA score and lateral radiograms were evaluated 1 week and 1 year postoperatively. Patie...

This study aimed to evaluate the improvement and maintenance of cervical lordosis and sagittal alignment after VBSO. METHODS: A total of 65 patients were included; 34 patients had undergone VBSO, and 31 had undergone anterior cervical corpectomy and fusion (ACCF). Preoperative, postoperative, and final follow-up radiographs were used to evaluate the improvements in cervical lordosis and sagittal alignment after VBSO. C0-2 lordosis, C2-7 lordosis, segmental lordosis, C2-7 sagittal vertical axis (SVA), T1 slope, thoracic kyphosis, lumbar lordosis, sacral slope, pelvic tilt, and Japanese Orthopaedic Association scores we...

CONCLUSIONS: In cases of severe infection with considerable bony destruction, insertion of an aPMMA strut graft is a novel technique that should be considered in order to provide strong anterior-column support while directly delivering antibiotics to the infection bed. While the active infection is being treated medically, this structural aPMMA support bridges the time it takes for the patient to be converted from a catabolic to an anabolic state, when it is ultimately safe to perform a definitive, curative fusion surgery.

Authors: Qiu X, Zhao B, He X, Zhao C, Leng Z Abstract BACKGROUND We compared the clinical and radiographic outcomes between interface fixation using absorbable screws and plate fixation in anterior cervical corpectomy and fusion (ACCF) to evaluate the effectiveness of these 2 fixation methods for the treatment of 2-level cervical spondylotic myelopathy (CSM). MATERIAL AND METHODS From January 2014 to December 2016, a total of 220 patients who received 2-level ACCF were retrospectively collected. Among them, 108 patients were treated with interface fixation using absorbable screws (Group A) and 112 patients underwen...

Abstract PURPOSE: For anterior spine column reconstruction after corpectomy, expandable cages offer solid anterior support and allow correction of deformity, providing excellent primary stability. To provide a larger body of clinical observations concerning the effectiveness of the approach, this retrospective study examines patients treated by corpectomy and reconstruction with an expandable cage for different pathologies. METHODS: Across 5 years, 39 patients underwent vertebral reconstruction with expandable cages after single (n = 34), double (n = 4), or triple (n = 1) corpectomy. Pathologies were tumors (...

CONCLUSIONS: VBSO provides similar neurologic outcomes with a shorter operating time and less bleeding compared with ACCF. Surgeons do not need to directly manipulate the OPLL mass or dissect the interspace between the OPLL and dura mater. Therefore, this technique may decrease the incidence of surgery-related complications. STUDY DESIGN: Retrospective comparative study. PMID: 31688427 [PubMed - as supplied by publisher]

This study aimed to analyze cervical alignment after single-level ACCF using autologous bone graft without spinal instrumentation for CPS compared with that for CDD.MethodsSix patients underwent single-level ACCF using autologous bone graft without spinal instrumentation for CPS. The control group included 18 age-matched patients who underwent single-level ACCF using autologous bone graft for CDD without spinal instrumentation for the same duration. Cervical and lateral plain radiographs and computed tomography scans were taken. The Frankel classification was used to assess the neurological status preoperatively, postopera...

The objective of this article is to assess the effect of screw migration and fracture associated with anterior cervical plating on long-term radiographic and clinical outcomes. Background Data: Screw migration and breakage detected after anterior cervical discectomy/corpectomy and fusion with plating may cause various implant-related complications and reduce solid fusion rate. However, little is known about their long-term prognosis. Materials and Methods: Medical records and radiographic data of 248 consecutive patients who underwent anterior cervical discectomy and fusion or anterior cervical corpectomy and fusion ...

AbstractIn contrast to a one-level cervical corpectomy, a multilevel corpectomy without posterior fusion is accompanied by a high material failure rate. So far, the adequate surgical technique for patients, who receive a two-level corpectomy, remains to be elucidated. The aim of this study was to determine the long-term clinical outcome of patients with cervical myelopathy, who underwent a two-level corpectomy. Outcome parameters of 21 patients, who received a two-level cervical corpectomy, were retrospectively analyzed concerning reoperations and outcome scores (VAS, Neck Disability Index (NDI), Nurick scale, modified Jap...
