Randomized Controlled Trial Multicenter Study Comparative Study
Who should have surgery for an intervertebral disc herniation? Comparative effectiveness evidence from the spine patient outcomes research trial.
Combined prospective randomized controlled trial and observational cohort study of intervertebral disc herniation (IDH), an as-treated analysis. ⋯ IDH patients who met strict inclusion criteria improved more with surgery than with nonoperative treatment, regardless of specific characteristics. However, being married, without joint problems, and worsening symptom trend at baseline were associated with a greater TE.

Randomized Controlled Trial Multicenter Study Comparative Study
The access randomized clinical trial of public versus private physiotherapy for low back pain.
Pragmatic randomized clinical trial. ⋯ Despite differences between public and private PT regarding waiting times for treatment and therapist experience, there were no significant differences between groups in the majority of clinical outcome measure scores at follow-up, apart from SF-36 Role Physical and satisfaction with treatment outcome in favor of the private PT group.

An anatomic study of anterior cervical dissection of 11 embalmed cadavers. ⋯ This study found that superior to C7-T1, both RLNs had similar anatomic courses and received similar protection via surrounding soft-tissue structures. From an anatomic perspective, the authors did not appreciate a side-to-side difference superior to this level that could place either nerve under greater risk for injury.

Intensity of pain and level of disability (Oswestry Disability Index [ODI]) were compared with the relative size of Modic type 1 (M1) and Modic type 2 (M2) lesions. Clinical symptoms of patients having mixed M1-M2 lesion (n = 49) were compared with patients having a "pure" M1 lesion (n = 13). ⋯ We conclude that the size of M1 lesion does not directly correlate with the clinical symptoms but that the type of Modic lesion is more important. This study supports the previous observations that when the inflammatory process turns to the mixed M1-M2 lesions, clinical symptoms decrease.

Case report. ⋯ We report a rare case of complete excision of an osteosarcoma of the C1 lateral mass in our patient via a direct lateral and posterior approach to secure additional fixation of occipitocervical joint. We describe our technique for reconstructing the lateral mass of the atlas. This reconstruction technique will also be applicable to other resection surgeries involving the occipitocervical junction.
