Sub-axial cervical spine(C spine) distraction flexion injuries, known as cervical sprains, have been divided into either "benign" or "severe" sprains depending on the integrity of the posterior longitudinal ligament (PLL) of the spinal column. It is a very uncommon injury and rarely reported in the literature. Most of the reports in the literature discuss this injury in the adult age group and so the adolescent age group was also considered to follow the same model of progression of mechanical instability depending on the degree and extent of structures injured, including the PLL as a cutoff factor between a "stable" and an "unstable" injury. ⋯ We report three cases of adolescents with severe cervical sprains at the C2-C3 level and argue the integrity of PLL as a determinant factor in the sagittal stability of the C spine in this age group.

Regardless of the etiology, severe cervical deformities can be extremely debilitating and are a challenge to correct. Often a multi-modality team approach is required to safely and effectively reduce the deformity, provide adequate decompression, and ensure solid fixation and fusion. In cases of iatrogenic cervical deformity necessitating five-level corpectomy and fixation, the feasibility, safety, and durability of this procedure remains unknown. ⋯ The feasibility and safety of five-level vertebrectomy and reconstruction for chin-on-chest deformity remains poorly described. The current case suggests that thoughtful planning that involves maximizing the patient's health status, judicious use of traction under direct neurological examination, staged circumferential release, and design of a construct that provides anterior and posterior column support with several points of fixation beyond the axis of rotation will attenuate the risk of peri-operative morbidity and potentiate the durability of deformity correction.

Review Meta Analysis
Mid- to long-term outcomes after cervical disc arthroplasty compared with anterior discectomy and fusion: a systematic review and meta-analysis of randomized controlled trials.
To evaluate the mid- to long-term clinical outcomes after cervical disc arthroplasty (CDA) as compared with anterior cervical discectomy and fusion (ACDF) for the treatment of symptomatic cervical disc disease. ⋯ CDA may result in better mid- to long-term functional recovery and a lower rate of subsequent surgical procedures than ACDF would. A review of the literature showed that only an insufficient number of studies had investigated adjacent segment disease; therefore, it is mandatory that adequate future research should focus in this direction.

Review Meta Analysis
Surgery in lumbar degenerative spondylolisthesis: indications, outcomes and complications. A systematic review.
This systematic review summarises the literature on patient selection, decision-making, effectiveness and outcomes in the surgical treatment of lumbar degenerative spondylolisthesis (LDS). ⋯ Despite there being many articles describing and/or comparing different surgical options for LDS, there was insufficient evidence to draw conclusions concerning clear indications for specific types of surgical treatment, predictors of outcome or complication rates. There remains a need to establish a decision-making tool to facilitate daily clinical practice and to assure appropriate treatment for patients with LDS.

Review Case Reports
Multifocal spinal malignant peripheral nerve sheath tumor in an immunocompromised individual: case report and review of literature.
Primary intraosseous spinal malignant peripheral nerve sheath tumor (MPNST) is exceedingly rare. MPNST with multifocal origin has been described to occur in the extremities. Such a lesion has not been described to occur in the spine. We describe a case of multifocal spinal MPNST and to review the literature relevant to this rare entity and its management. ⋯ Multifocal spinal MPNST is a rare lesion. In this instance, the multifocality of the disease and its odd location could be attributed to the immunodeficiency state. The prolonged survival could be due to an improvement in his immune status due to HAART.
