Use of Polyetheretherketone Devices May Up Pseudarthrosis

THURSDAY, Nov. 8, 2018 -- For one-level anterior cervical discectomy and fusion (ACDF), use of polyetheretherketone (PEEK) devices is associated with significantly higher rates of radiographically demonstrated pseudarthrosis and need for revision...

J Neurol Surg B DOI: 10.1055/s-0040-1701680This video demonstrates the transmastoid suprajugular approach with neck dissection to a solitary fibrous tumor involving the jugular foramen and upper cervical region. This patient was a 39-year-old man who presented with dysphagia and cranial nerve (CN) XI and CN XII palsies. Imaging revealed a large homogenously enhancing lesion involving the jugular foramen and extending into the retropharyngeal space (Fig. 1). Radiographic findings supported a diagnosis of jugular foramen schwannoma. After an initial period of observation, the tumor demonstrated significant growth, and the pa...

CONCLUSIONS: The authors found that the best indicator of bone union was the item bridging bone on ≥ 3 CT slices. Combining the scoring of more than one criterion did not increase the diagnostic accuracy. PMID: 32114527 [PubMed - as supplied by publisher]

Conclusions: For one-level ACDF, the anchored cage with screws has some advantage compared to the stand-alone PEEK cage in avoiding dysphagia and restoring disc space height and cervical lordosis. We suggest the anchored spacer may be a good substitute for the stand-alone cage in one-level ACDF. Level of Evidence: Level II

This study compared the surgical outcomes of two surgical methods for treating multilevel cervical spondylotic myelopathy (MCSM) combined with cervical kyphotic deformity (CKD): (1) the ELTA method consisted of expansive open-door laminoplasty (EOLP) followed by three-segment anterior cervical discectomy fusion (ACDF), and (2) the LAPI method consisted of long-segment ACDF followed by long-level posterior instrumented fusion (PIF). Surgical treatment of CKD combined with MCSM remains challenging. Surgical considerations should include adequate spinal cord decompression and restoration of satisfactory cervical sagittal alig...

Conclusion. An early self-directed HEP program was acceptable to patients and has the potential to be safely administered to patients immediately after ACDF. Benefits were noted for short-term neck pain and long-term opioid utilization. However, larger trials are needed to confirm safety with standardized and long-term radiograph assessment and treatment efficacy. Level of Evidence: 2

Abstract OBJECTIVE: Common interbody graft options for anterior cervical discectomy and fusion (ACDF) include allograft and polyetheretherketone (PEEK). PEEK has gained popularity due to its radiolucent properties and a modulus of elasticity similar to that of bone. PEEK devices also result in higher billing costs than allograft, which may drive selection. A previous study found a 5-fold higher rate of pseudarthrosis with the use of PEEK devices compared with structural allograft in single-level ACDF. Here the authors report on the occurrence of pseudarthrosis with PEEK devices versus structural allograft in patie...

AbstractBackgroundMultilevel cervical degenerative disc disease (CDDD) can be treated surgically with anterior cervical discectomy and fusion (ACDF), cervical disc arthroplasty (CDA), or a hybrid surgery (HS) of the two in which both procedures are used at different vertebral levels. A systematic review and meta-analysis was performed to compare the clinical and radiographical outcomes of HS against ACDF or CDA alone.MethodsThree electronic databases were searched for articles published before December 2018. The literature was searched and assessed by independent reviewers according to the Preferred Reporting Items for Sys...

CONCLUSION: As the management paradigms of tandem occlusions continue to evolve, this technique may improve outcomes by expediting endovascular intervention. Using the stent retriever wire provides a method of expediting the management of the proximal lesion after addressing the more distal intracranial occlusion first.

Conclusions: This study provides normative data on SEm and MDC for Cobb angles, T1S, KLT, OCI, and cSVA in cervical lateral radiographs. Reliability was excellent for all parameters except SABB (e.g., good). PMID: 31668048 [PubMed - as supplied by publisher]
