Comparative StudyA comparison of anterior and posterior instrumentation for restoring and retaining sagittal balance in patients with idiopathic adolescent scoliosis.
Retrospective, comparative study. ⋯ Anterior solid rod-screw instrumentation results in shorter fusion segments, and better sagittal alignment and quality of life than posterior pedicle screw instrumentation in patients with Lenke type 5 AIS.

Claustrophobia: a proxy for psychological distress in patients with back pain.
Case-control study. ⋯ Claustrophobic patients with back pain showed higher levels of depression than nonclaustrophobic patients, with a higher rate of psychological distress. Disability, however, was not higher. The majority of claustrophobic patients did not require surgical intervention. The reasons for this are unclear and require further investigation. Claustrophobia requiring sedation for MRI scans may be a proxy for psychological distress in these patients and psychometric testing is advised during assessment to help with surgical decision making.

Nucleoplasty is effective in reducing both mechanical and radicular low back pain: a prospective study in 87 patients.
A prospective study of all patients with either mechanical back pain or radicular back pain who underwent nucleoplasty and were followed up prospectively. ⋯ We concluded that the nucleoplasty technique is a safe and effective procedure for radicular or combined radicular and mechanical low back pain and should be used in selected cases before open surgery after conservative treatment has failed.

Lumbarized sacrum as a relative contraindication for lateral transpsoas interbody fusion at L5-6.
Retrospective review. ⋯ Treating the L5-6 level using a lateral transpsoas approach in individuals with lumbarized sacra can be challenging due to anatomy more similar to the L5-S1 level in normal patients. Preoperative planning using axial MRI and intraoperative adherence to advanced neuromonitoring can aid in identifying and avoiding injury in these rare patients.

Comparative Study Clinical TrialQuantitative volumetry of cement leakage in viscosity-controlled vertebroplasty.
This study was designed as a cohort study comparing a prospective sample to a historic control group. ⋯ The use of viscosity-controlled vertebroplasty led to a decrease in the leakage rate from 58.3% to 42.1%. Leakage into the basivertebral vein with the risk of compression of nerval structures was reduced to almost 50% when viscosimetry was performed. It revealed to be a helpful tool for more unexperienced surgeons to assess the appropriate viscosity for vertebroplasty.
