Outcomes of C1 and C2 posterior screw fixation for upper cervical spine fusion
. Eur Spine J 2009;18 Suppl 1:2-6.
Study findings showed that after ACDF surgery, use of PEMF stimulation significantly increased the fusion rate relative to the control group at six and 12 months for participants who were at risk for pseudoarthrosis.1 Participants included patients who had a risk factor that could impair their cervical spine fusion
success; or they had a risk factor and received at least a two- or three-level arthrodesis.The evaluations were conducted with historical data from Orthofix's prospective, randomized, multicenter FDA investigational device exemption PMA study of 323 patients conducted in 2014 and a new multicenter, retrospective cohort study consisting of 274 patients enrolled at three institutions.

Screw loosening and consequent pharyngeal perforation are an uncommon, but well recognized, occurrence for ventral cervical spine fusion
operations in literature [13-16].
Given the high frequency of ACDF operations, there have been reports of complications stemming from this procedure, such as the formation of pseudarthrosis, severe degeneration of adjacent segments, height reduction of the intervertebral space (IVS), and motion loss of the cervical spine fusion

Importantly, the incidence of cervical spine fusion
was statistically identical between study groups, and was consistent with figures reported in other studies.

Cervical spine surgery in rheumatoid arthritis: improvement of neurologic deficit after cervical spine fusion
These mechanisms include recurrent and/or superior laryngeal nerve injury, pharyngeal plexus injury, scarring of the pharynx itself, and the physical impeding of bolus transfer secondary to the presence of "hardware." The postoperative incidence of dysphagia following an anterior-approach cervical spine fusion
has been reported to be 50.2% at 1 month, 32.2% at 2 months, 17.8% at 6 months, and 12.5% at 12 months.
