BACKGROUND The aim of this study was to evaluate the clinical and radiological outcomes of the use of a new 3D-printed anatomy-adaptive titanium mesh cage (AA-TMC) for single-level anterior cervical corpectomy and fusion (ACCF) in patients with cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL). MATERIAL AND METHODS We retrospectively reviewed the records of 15 consecutive patients who underwent ACCF surgeries with AA-TMC implantation. The Japanese Orthopedic Association (JOA) scoring system, a visual analogue scale (VAS), the mean intervertebral height (MIBH) of the surgical segments, and the surgical segmental angle (SSA) were recorded preoperatively, immediately after surgery and at the final follow-up visit...

INTRODUCTION: Traumatic spinal subdural hematoma involving the retroclival region and upper cervical spine is a rare pathology. To our knowledge, there have only been two prior cases in an adult trauma patient. We describe a patient with pre-existing Chiari 1 malformation, who recently sustained a unilateral Type 1 OCF (occipital condyle fracture) with associated disruption of the tectorial membrane and transverse ligament, that returned with a retroclival subdural hematoma extending down to C7, causing spinal cord compression and symptomatic obstructive hydrocephalus...

Extreme long-term clinical outcome studies following anterior cervical discectomy and fusion (ACDF) with an autologous iliac crest with and without Caspar plating (ACDF + CP) for the treatment of radiculopathy caused by cervical disc herniation (CDH) are extremely rare. Hospital records of patients who underwent ACDF or ACDF + CP for the treatment of CDH at least 17 years ago were reviewed. Information about diagnosis, surgery, pre- and postoperative clinical process, and repeated procedure was analyzed...

BACKGROUND CONTEXT: The process of linear growth is driven by axial elongation of both long bones and vertebral bodies and accomplished by enchondral ossification. Differences in regulation between the two skeletal sites are mirrored clinically by the age course in body proportions. Whereas growth plates in long bones can easily be discriminated, vertebral growth plates are part of the cartilaginous endplate, which typically shows important species differences. PURPOSE: To describe and compare histological, histomorphometric and regulatory characteristics in the growth plates of the spine and long bones in a porcine model...

RATIONALE: Solitary eosinophilic granuloma (EG), the most benign, common form of Langerhans cell histiocytosis, has a self-limiting process and is associated with a good prognosis. Immobilization is recommended as the first treatment strategy for solitary EG, although the treatment protocols are still controversial. Radiotherapy and surgery are secondary treatment choices. Lesions of the upper cervical spine react differently to treatment because of their specific anatomical and motor features...

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...

BACKGROUND: Surgeons often choose between 2 different approaches (anterior and posterior) for surgical treatment of degenerative cervical myelopathy on the basis of imaging features of spinal cord compression, the number of levels affected, and the spinal alignment. However, there is a lack of consensus on which approach is preferable. The objective of the present study was to use magnetic resonance imaging (MRI)-based propensity-score-matched analysis to compare postoperative outcomes between the anterior and posterior surgical approaches for degenerative cervical myelopathy...

Type II odontoid fractures represent the most common cervical spine injury in the elderly. The decision for surgical treatment is still controversial, particularly with regard to the elevated perioperative risk attributed to frequent comorbidities and poor bone quality. Purpose of this study was to assess both short-term mortality and mid-term clinical and radiological outcome in the elderly. Between January 2007 and December 2015, 35 patients with type II odontoid process fractures who underwent posterior atlanto-axial instrumentation using a modified Goel-Harms technique were retrospectively analyzed and prospectively examined clinically and radiologically...

BACKGROUND: In multilevel degenerative conditions posterior approaches are often preferred, but anterior approaches provide comparable clinical results and better alignment. Anterior plating entails higher rates of soft tissue injuries and dysphagia, particularly in multilevel cases. This study evaluates efficacy and safety of zero-profile devices in three and four-level ACDF, analyzing patients' clinical and radiological long-term outcome. METHODS: We prospectively enrolled 24 patients with cervical spondylotic myeloradiculopathy (CSM), who underwent three and four-level ACDF with Zero-P device...

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...

Injury to the thoracic duct during anterior cervical spine surgery is a rare occurrence. A delayed chyle leak following an elective anterior cervical spinal surgery has not been reported in the literature. We present a report of a 59-year-old female with multiple prior neck surgeries who underwent an anterior cervical corpectomy and fusion (ACCF). The patient developed a delayed thoracic duct injury on postoperative day (POD) one, as no injury was noted intraoperatively. She was managed with conservative care involving a low-fat diet along with octreotide which led to the resolution of her symptoms...

BACKGROUND: Cervical spondylotic myelopathy (CSM) is the leading cause of spinal cord dysfunction in the world. Surgical treatment is both medically and economically advantageous, and can be achieved through multiple approaches, with or without fusion. We used the Nationwide Inpatient Sample (NIS) database to better elucidate regional and socioeconomic variances in the treatment of CSM. METHODS: The NIS database was queried for elective admissions with a primary diagnosis of CSM (ICD-9 721...
