“…First, surgical indication has been expanded to complex deformities and instabilities as well as patients with DSA and RA complicated by substantial bone fragility. 12,18,26,28,29 Consequently, the incidence in our current practice may well be higher than the value reported in previous literature. Incidentally, incidence of patients without poor bone quality such as either RA or DSA was 2.6%, which corresponds to the value reported in previous studies.…”

Object Although lateral mass screw fixation for the cervical spine is a safe technique, lateral mass fracture during screw fixation is occasionally encountered intraoperatively. This event is regarded as a minor complication; however, it poses difficulties in management that may affect fixation stability and clinical outcome. The purpose of this study is to determine the incidence and etiology of lateral mass fractures during cervical lateral mass screw fixation. Methods A retrospective clinical review of patient records was performed in 117 consecutive patients (mean age 57 years, range 15–86 years) who underwent lateral mass screw fixation using a modified Magerl method from 1997 to 2010 at a single institution. A total of 555 lateral masses were included in this study. The outer diameters of the screws were 3.5 or 4.0 mm. In the retrospective clinical analysis, the incidence of intraoperative lateral mass fractures was reviewed. Potential risk factors for this complication were assessed using multivariate analysis. Results The incidence of lateral mass fractures during cervical lateral mass screw fixation was 4.7% (26 lateral masses) among all cases. Among the disorders, the incidence was highest in patients with destructive spondyloarthropathy (DSA) (18.8%, 12 lateral masses). There was no significant difference with respect to lateral mass fracture between the use of 4.0-mm screws (5.6%) and 3.5-mm screws (3.6%). Independent risk factors identified by logistic regression were DSA (OR 7.89, p < 0.001) and screw insertion in the C-6 lateral masses (OR 2.80, p = 0.018). Conclusions The overall incidence of lateral mass fracture during cervical lateral mass screw fixation was 4.7%. Destructive spondyloarthropathy as an underlying cause of morbidity and screw placement in the C-6 lateral mass were identified as independent risk factors. Use of a 4.0-mm screw in patients with DSA may be a principal risk factor for this complication.

“…Due to the biomechanical superiority of the PS system in spinal reconstruction surgery, it has been used for patients with cervical deformities or unstable pathological conditions such as acute traumatic lesions, subaxial lesions of RA, destructive spondyloarthropathy due to long-term hemodialysis and tumor metastasis to the cervical spine [1][2][3][4][5]. Recent clinical applications of the PS system include correction of kyphotic deformity in the cervical spine and occipitocervical reconstruction to correct malalignment in the craniocervical junction caused by various pathological conditions [14].…”

“…There have been increasing reports of posterior instrumentation surgery with cervical pedicle screws (PSs) for reconstruction of the cervical spine with various pathologies [1][2][3][4][5]. Despite the biomechanical superiority of cervical PSs [6], placement of cervical PSs inherits considerable risks of injuries either to nerves or to vertebral artery.…”

“…Several reports have shown that some of the factors [5] promoting the progression of degenerative changes of the cervical spine were excessive load on the spine [6,19], a past history of lumbar vertebral diseases [17], smoking [12], and hemodialysis [20,25,27]. Jumah et al [19] investigated the factors promoting degeneration of the cervical spine in 305 Ghanans and found that 63.6% of the subjects who routinely carried baggage on their head had spondylotic changes of the cervical spine, while only 36.0% of those who did not habitually carry loads showed such changes.…”

Does the sagittal alignment of the cervical spine have an impact on disk degeneration? Minimum 10-year follow-up of asymptomatic volunteers

There have been few studies that investigated and clarified the relationships between progression of degenerative changes and sagittal alignment of the cervical spine. The objective of the study was to longitudinally evaluate the relationships among progression of degenerative changes of the cervical spine with age, the development of clinical symptoms and sagittal alignment of the cervical spine in healthy subjects. Out of 497 symptom-free volunteers who underwent MRI and plain radiography of the cervical spine between 1994 and 1996, 113 subjects (45 males and 68 females) who responded to our contacts were enrolled. All subjects underwent another MRI at an average of 11.3 years after the initial study. Their mean age at the time of the initial imaging was 36.6 ± 14.5 years (11-65 years). The items evaluated on MRI were (1) decrease in signal intensity of the intervertebral disks, (2) posterior disk protrusion, and (3) disk space narrowing. Each item was evaluated using a numerical grading system. The subjects were divided into four groups according to the age and sagittal alignment of the cervical spine, i.e., subjects under or over the age of 40 years, and subjects with the lordosis or non-lordosis type of sagittal alignment of the cervical spine. -009-1095-5 During the 10-year period, progression of decrease in signal intensity of the disk, posterior disk protrusion, and disk space narrowing were recognized in 64.6, 65.5, and 28.3% of the subjects, respectively. Progression of posterior disk protrusion was significantly more frequent in subjects over 40 years of age with non-lordosis type of sagittal alignment. Logistic regression analysis revealed that stiff shoulder was closely correlated with females (P = 0.001), and that numbness of the upper extremity was closely correlated with age (P = 0.030) and male (P = 0.038). However, no significant correlation between the sagittal alignment of the cervical spine and clinical symptoms was detected. Sagittal alignment of the cervical spine had some impact on the progression of degenerative changes of the cervical spine with aging; however, it had no correlation with the occurrence of future clinical symptoms.123 Eur Spine J (2009) 18:1644-1651 DOI 10.1007/s00586
