Cervical Total Disc Replacement and Heterotopic Ossification: A Review of Literature Outcomes and Biomechanics.

Cervical Total Disc Replacement and Heterotopic Ossification: A Review of Literature Outcomes and Biomechanics. Asian Spine J. 2020 Feb 14;: Authors: Hui N, Phan K, Kerferd J, Lee M, Mobbs RJ Abstract Anterior cervical discectomy and fusion (ACDF) immobilizes surgical segments and can lead to the development of adjacent segment degeneration and adjacent segment disease. Thus, cervical total disc replacement (CTDR) has been developed with the aim to preserve the biomechanics of spine. However, heterotopic ossification (HO), a complication following CTDR, can reduce the segmental range of motion (ROM) and defects the motion-preservation benefit of CTDR. The pathological process of HO in CTDR remains unknown. HO has been suggested to be a self-defense mechanism in response to the non-physiological biomechanics of the cervical spine following CTDR. The current literature review is concerned with the association between the biomechanical factors and HO formation and the clinical significance of HO in CTDR. Endplate coverage, disc height, segmental angle, and center of rotation may be associated with the development of HO. The longer the follow-up, the higher the rate of ROM-limiting HO. Regardless of the loss of motion-preservation benefit of CTDR in patients with HO, CTDR confers patients with a motion-preservation period before the development of ROM-limiting HO. This may delay the development of adjacent segment degeneration compared with ACDF. Future clini...

Conclusions: ACDF utilization increased most rapidly in the outpatient setting, and CON status did not appear to hinder growth. Reimbursement decreased across all settings, with the outpatient setting in non-CON states most affected. Surgeons should be aware of these trends in the changing health care environment.

Conclusions: Through this systemic review and meta-analysis, no significant difference was found with regards to fusion rate, postoperative NDI, and VAS between tantalum fusion and iliac crest bone graft in ACDF. More longer-term and randomized studies with large samples are warranted to validate any association found in this study. Level of Evidence: Level II.

AbstractWe suggested operative techniques and indications of robotic neck surgery. To determine operative techniques and the indications for robotic neck surgery, we analyzed treatment outcomes of patients who received robotic neck surgery. Between May 2010 and July 2018, a total of 945 patients with various neck diseases visited Severance Hospital and underwent robotic neck surgery. A variety of approaches, including the retroauricular approach (RA), modified facelift approach (MFLA), transaxillary approach (TA), and transaxillary retroauricular approach (TARA), was used to remove various tumors in the neck. A total of 23...

Anterior cervical discectomy with an interbody cage (ACDF) to obtain fusion is a common procedure in cervical spine surgery. Presently, PEEK with (auto)graft is frequently used for interbody fusion although alternative implant technology like 3-D printing titanium has been introduced recently.

CONCLUSION: SSP change after 1- or 2-level ACDF correlates mostly weakly with GSP change. Male gender and osteoporosis were identified as risk factors for global lordotisation following ACDF. PMID: 32158016 [PubMed - as supplied by publisher]

Study Design. Retrospective study. Objective. To investigate the associated risk factors for acute respiratory distress after multilevel anterior cervical discectomy and fusion (ACDF) with a focus on the subjective symptom, dyspnea. Summary of Background Data. Acute respiratory distress after ACDF is a relatively common adverse event, the cause of which is usually soft tissue swelling or hematoma. It can result in serious morbidity and requires careful, focused treatment. Methods. We reviewed the records of 532 patients (from January 2014 to August 2018) who had undergone multilevel ACDF surgery. Acute respirato...

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...

The current standard of care for clinically N0 patients at risk for cervical lymph node metastases is to undergo neck dissection for completion of staging, as the status of the cervical lymph node basins at the time of diagnosis provides important information about prognosis and treatment planning. However, up to 70% of cN0 patients have no nodal disease and thus underwent unnecessary surgery. The aim of this study is to identify an easily available peripheral blood biomarker that could serve as a marker of occult nodal metastases in cN0 patient with oral cavity squamous cell carcinoma (OCSSCa).
