Vertebral End Plate Perforation for Intervertebral Disc Height Preservation After Single Level Lumbar Discectomy: A Randomized Controlled Trial.
Pilot single-centre, stratified, prospective, randomized, double-blinded, parallel-group, controlled study. ⋯ The present study showed positive correlation between the volume of removed disc tissue and decrease in postoperative ISV and ISH. There were no statistically significant differences in ISV and ISH between the group with end-plate perforation and the control group six months after lumbar discectomy. Clinical outcome and disability were significantly improved in both groups three and six months after surgery.

Measurement of Thoracic Inlet Alignment on MRI: Reliability and the Influence of Body Position.
A retrospective radiographic study. ⋯ MRI serves as a good substitute for X-ray scans with regard to the measurement of TI alignment, with superior reliability.

Does the position of the aorta change with the altered body position in Ankylosing Spondylitis patients with thoracolumbar kyphosis?-A Magnetic Resonance Imaging Investigation.
A prospective magnetic resonance imaging (MRI) study. ⋯ There is no significant change of the relative positions between the aorta and the vertebrae at T9-L3 levels after the patient turned to a prone position, which implied that the mobility and range of motion of the aorta is limited in advanced stage of AS.

BMP-2-induced Neuroforaminal Bone Growth in the Setting of a Minimally Invasive Transforaminal Lumbar Interbody Fusion.
Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) has become a popular alternative to traditional methods of lumbar decompression and fusion. When compared with the open technique, the minimally invasive approach can result in decreased pain and blood loss as well as a shorter length of hospitalization. However, the narrower working channel through the tubular retractor increases the difficulty of decortication and bone grafting. ⋯ If this bone growth compresses the neighboring neural structures, patients may present with either new or recurrent radicular pain. Computed tomographic (CT) imaging can demonstrate heterotopic bone growth extending from the disk space into either the ipsilateral neuroforamen or lateral recess, which may result in the compression of the exiting or traversing root, respectively. The purpose of this article and the accompanying video is to demonstrate a technique for defining and resecting rhBMP-2-induced heterotopic bone growth following a previous MIS-TLIF.

Comparative StudyZero-profile Anchored Spacer Reduces Rate of Dysphagia Compared With ACDF With Anterior Plating.
Retrospective cohort study. ⋯ Zero-profile anchored spacers lead to similar clinical and radiographic outcomes compared with ACDF with plating and may carry a lower risk of postoperative dysphagia.
