BACKGROUND: Pseudarthrosis after anterior cervical discectomy and fusion (ACDF) causes persistent pain and related disability. Posterior revision surgery results in higher healing rates, but is more extensive compared to anterior surgery. OBJECTIVE: To evaluate minimally disruptive, tissue sparing posterior fusion via bilateral placement of posterior cages between the facet joints as an alternative treatment option. METHODS: A retrospective, multicenter, medical chart review was performed and included 25 patients with symptomatic pseudarthrosis after ACDF treated with posterior cervical cages, and in select cases, anterior revision...

BACKGROUND: The graft site morbidity following iliac crest harvesting is significant. To overcome this, different bone substitutes like coral dowels, solvent dissolved bovine/human bone substitutes, and carbon fiber/titanium cages have been used. This study was undertaken to assess the postoperative radiological fusion rates and symptom relief in patients who had Tutobone used as an interbody spacer compared to autologous bone graft (ABG), cages, surgibone and coral dowels. METHODS: This was a retrospective, observational study...

BACKGROUD CONTEXT: Many meta-analyses have been performed to study the efficacy of cervical disc arthroplasty (CDA) compared with anterior cervical discectomy and fusion (ACDF); however, there are few data referring to adjacent segment within these meta-analyses, or investigators are unable to arrive at the same conclusion in the few meta-analyses about adjacent segment. With the increased concerns surrounding adjacent segment degeneration (ASDeg) and adjacent segment disease (ASDis) after anterior cervical surgery, it is necessary to perform a comprehensive meta-analysis to analyze adjacent segment parameters...

STUDY DESIGN: This is a meta-analysis of controlled trials. OBJECTIVE: To assess the overall condition of adjacent segment of cervical disk arthroplasty (CDA) compared with anterior cervical discectomy and fusion (ACDF). SUMMARY OF BACKGROUND DATA: With the increase in CDA and ACDF, surgeons are taking more attention to adjacent segment degeneration (ASDeg) and adjacent segment disease (ASDis). There are more and more meta-analyses comparing the efficacy of CDA with ACDF, however, there are few meta-analyses referring to adjacent segment parameters, and investigators are still unable to arrive at the same conclusion...

STUDY DESIGN: Retrospective comparative study. OBJECTIVE: To investigate whether unilateral or bilateral uncinate resection (UR) combined with anterior cervical discectomy and fusion (ACDF) increases the risk of pseudarthrosis at long-term follow-up. SUMMARY OF BACKGROUND DATA: Uncoforaminotomy (or UR), performed along with ACDF, facilitates better and faster improvement of arm pain. As uncovertebral joints are important for maintaining stability, they may affect the fusion process by causing segmental instability if resected during ACDF...

A 23-year-old male trauma patient with a cervical spine fracture underwent an anterior and posterior discectomy and spinal fusion surgery. The patient presented to the operating room with a stabilizing halo fixation device in place, and a fiberoptic intubation was performed with dexmedetomidine for sedation. During the surgical procedure, general anesthesia was maintained with a propofol and remifentanil infusion as the patient was monitored using somatosensory and motor evoked potentials. The patient's urine output increased gradually during the nine-hour surgical procedure from 150 mL/hour to over 700 mL/hour in the eighth hour of the procedure, where it remained until the end of the procedure...

Esophageal perforation is a dreaded complication of anterior cervical spinal surgery. A 52-year-old diabetic man had undergone a surgery for a C6-C7 disc prolapse and developed spiking fever with chills and rigor on the 7th postoperative day. No cause could be found out but a CT scan of thorax done in the course of investigations revealed pneumomediastimum. The patient succumbed on the 10th day after surgery. Autopsy revealed the cause of death to be mediastinitis following iatrogenic esophageal perforation...

BACKGROUND: The V2 segment of the vertebral artery (VA) typically runs through the transverse foramen of C2-C6. V2 injury may occur during anterior approaches to the cervical spine and can cause significant morbidity. We aimed to describe landmarks and microsurgical V2 repair techniques through the standard anterolateral cervical discectomy approach. METHODS: Five silicone-injected cadaveric heads (necks-C7) were dissected bilaterally. An anterolateral approach with C3-4, C4-5, and C5-6 discectomies and an ipsilateral VA injury were simulated...

Cervical degenerative disease is one of the most common spinal disorders worldwide, especially in older people. Anterior cervical corpectomy and fusion (ACCF) is a useful method for the surgical treatment of multi-level cervical degenerative disease. Anterior cervical disc replacement (ACDR) is considered as an alternative surgical method. However, both methods have drawbacks, particularly the neck motion decrease observed after arthrodesis, and arthroplasty should only be performed on patients presenting with cervical disc disease but without any vertebral body disease...

BACKGROUND CONTEXT: The results of meta-analyses are frequently reported, but understanding and interpreting them is difficult for both clinicians and patients. Statistical significances are presented without referring to values that imply clinical relevance. PURPOSE: To use the minimal clinically important difference (MCID) to rate the clinical relevance of a meta-analysis. STUDY DESIGN: Review of the literature. PATIENT SAMPLE: meta-analyses OUTCOME MEASURE: MCID METHODS: We performed an extensive literature search of a series of meta-analyses evaluating a similar subject as an example...

BACKGROUND: Anterior cervical decompression and fusion (ACDF) is a widely accepted surgical technique for the treatment of degenerative disc disease. ACDF is associated with adjacent segment degeneration (ASD). OBJECTIVE: To assess whether physiological aging of the spine would overcome ASD by comparing adjacent to adjoining segments more than 18 yr after ACDF. METHODS: Magnetic resonance imaging of 59 (36 male, 23 female) patients who underwent ACDF was performed to assess degeneration...

BACKGROUND: Minimally invasive surgery (MIS) spine procedures were developed to limit operative time, the extent of dissection, and reduce perioperative morbidity. Here, we asked what are the "learning curves" for these MIS spine procedures? METHODS: We reviewed studies in the literature that discussed the "learning curves" attributed to performing different MIS spine surgical procedures. Of interest, the majority were single-surgeon series. RESULTS: Very few articles assessed the learning curves for different MIS spine procedures...
