Surgical treatment of sacral chordomas combined with transcatheter arterial embolization.
A retrospective study, analyzing midterm results of transcatheter arterial embolization (TAE) for removal of a sacral chordoma. ⋯ In comparison with historical literature, preoperative TAE for excising the sacral tumor can significantly decrease intraoperative blood loss, make the surgical field clear, possibly eliminate the need for using an anterior approach, and facilitate the maximal removal of the sacral chordoma. It is an encouraging technique for excising the sacral chordomas.

Randomized Controlled Trial Multicenter Study Comparative StudyLower incidence of dysphagia with cervical arthroplasty compared with ACDF in a prospective randomized clinical trial.
The current study of 251 consecutive 1-level anterior cervical reconstructions was undertaken to compare the incidence of dysphagia between cervical disk replacement and conventional anterior cervical fusion and instrumentation. ⋯ In a prospective randomized clinical study the incidence of postoperative dysphagia and the long-term resolution of the dysphagia was greatly improved in the PCM group compared with the instrumented ACDF control group.

Comparative StudyA short report comparing outcomes between L4/L5 and L5/S1 single-level discectomy surgery.
Prospective cohort study. ⋯ This is the first study comparing a discectomy outcome at L4/L5 and L5/S1 with complete preoperative data. No significant difference exists between the 2 levels in terms of postoperative outcome. Surgical procedures such as fusion or arthroplasty should not be carried out synchronous with primary discectomy for radiculopathy. The lack of a difference between L4/L5 and L5/S1 reinforces the fact that the mechanical environment does not affect outcome and should not influence treatment.

Preoperative radiographic factors and surgeon experience are associated with cortical breach of C2 pedicle screws.
A retrospective review study. ⋯ During placement of C2 pedicle screws, likelihood of cortical breach may be associated with size of pedicle and surgeon experience. Extensive preoperative evaluation of CT scans and consideration of technical demands of procedure may help avoid complications with such internal fixation.

Clinical outcomes after microendoscopic discectomy for recurrent lumbar disc herniation.
Retrospective review of consecutive case series. ⋯ MED is a safe and effective surgical approach for the treatment of recurrent lumbar disc herniation. Standardized measures of outcome show that MED for recurrent herniation produces improvement in pain, disability, and functional health that is at least comparable with outcomes reported for conventional open microdiscectomy.
