We aimed to identify technique-related factors influencing radiographic and patient-rated outcomes after two-level anterior cervical discectomy with fusion (ACDF) using either cage or autologous bone, with or without anterior plate fixation (APF). ⋯ Adding APF was associated with greater segmental height and preservation of lordosis in two-level ACDF, especially using bone autograft, but also for cage. Clinical outcome was comparable for all groups. Though the surgical technique per se did not determine clinical outcome, patients achieving a greater segmental height difference showed a significantly better GTO.

Neuroblastoma is the most common extra-cranial solid tumour in children. Metastasis in children to the upper cervical spine are quite rare. ⋯ This is the first report of the use of a trans-oral approach to address a neuroblastoma lesion in the axial spine. This approach was used effectively to achieve local tumour clearance confirmed at 1-year follow-up. Pertinent information to the spinal surgeon on neuroblastoma and the use of the trans-oral approach to the axial spine are discussed.

Flat-back syndrome is one of the main causes of surgical failure after lumbar fusion and can lead to a revision surgery to correct it. Three-column pedicle subtraction osteotomy is an efficient technique to restore lumbar lordosis (LL) for fixed sagittal malalignment. The fusion mass stemming from the past surgeries makes the procedure demanding as most anatomical landmarks are missing. ⋯ PSO in the fixed fusion mass is technically demanding. Preoperative CT-scan and preoperative navigation allow us to push the limits when anatomical landmarks disappear. Bleeding and neurologic are the two major complications feared by the surgeon. The best way to avoid these revision surgeries is to restore a proper lumbar lordosis at the time of initial surgery by considering lumbo-pelvic indexes.

Traumatic central cord syndrome (TCCS) is the most commonly encountered type of incomplete spinal cord injury. TCCS typically occurs in patients over the age of 50 with a narrow spinal canal and follows an acute hyperextension injury of the cervical spine. Here, we report on the demographics of TCCS patients, their clinical course and outcomes, and the factors that may have influenced these outcomes. ⋯ The Groote Schuur Hospital patient population differs from the international norm, particularly with respect to age and mechanism of injury. The ASIA motor score and cervical spine canal diameter proved to be useful predictors of outcome. Within our patient group, timing of surgery did not appear to influence the outcome.

Pedicle screw instrumentation provides optimal stabilization of the cervical spine complex, but is associated with risk of neurovascular injury. Sex and ethnic disparities may compromise safe and accurate screw placement. Therefore, a comprehensive analysis of pedicle dimensions derived from computed tomography scans is pertinent for our multi-ethnic population. ⋯ Transpedicular screw fixation is generally feasible in our population except for 8 % with at least one PW < 4.00 mm. However, in view of significant sex and ethnic morphometric variability, pre-operative CT evaluation together with image-guided screw placement is highly advised to ensure safety and accuracy.
