Randomized Controlled Trial
PREPARE: presurgery physiotherapy for patients with degenerative lumbar spine disorder: a randomized controlled trial.
Surgery because of disc herniation or spinal stenosis results mostly in large improvement in the short-term, but mild to moderate improvements for pain and disability at long-term follow-up. Prehabilitation has been defined as augmenting functional capacity before surgery, which may have beneficial effect on outcome after surgery. ⋯ Presurgery physiotherapy decreases pain, risk of avoidance behavior, and worsening of psychological well-being, and improves quality of life and physical activity levels before surgery compared with waiting-list controls. These results were maintained only for activity levelspost surgery. Still, presurgery selection, content, dosage of exercises, and importance of being active in a presurgery physiotherapy intervention is of interest to study further to improve long-term outcome.

Comparative Study
Safety and accuracy of freehand versus navigated C2 pars or pedicle screw placement.
C2 pedicle and pars screws require accurate placement to avoid injury to nearby neurovascular structures. Freehand, fluoroscopically guided, and computed tomography (CT)-based navigation techniques have been described in the medical literature. ⋯ In patients with postoperative CT imaging (43%), the freehand technique was found to be more accurate than CT-based navigation for C2 pedicle or pars screw placement. Complication rates did not differ between the two techniques in this study.

Dysphagia has been recognized as one of the most serious complications after occipitocervical fusion (OCF), and the difference between postoperative and preoperative O-C2 angle (dO-C2A) was proposed to be an indicator in predicting and preventing dysphagia. Therefore, to prevent postoperative dysphagia, previous studies recommend that surgeons should correct the O-C2 angle (O-C2A) during surgery if the occipitocervical alignment was in an excessively flexed position. However, until now, there was no explicit indicator of the condition in which surgeons should adjust the patient's O-C2A during surgery. ⋯ The present study showed that the dO-C2A should be a key factor in the development of postoperative dysphagia after OCF. A dO-C2A of -5° could be the threshold between dysphagia and normal swallowing. Furthermore, to avoid dysphagia, surgeons should correct the O-C2A just before the final occipitocervical fixation if the checked dO-C2A during surgery is less than -5°.

Percutaneous endoscopic lumbar discectomy (PELD) is one of minimally invasive techniques to treat patients with low back and radiating pain resulting from lumbosacral disc herniation (LDH). ⋯ PELD was an effective treatment in patients with back and leg pain due to LDH. Positive SLR had the predictive ability to successful reduction of radiating leg pain and successful functional improvement. Longer pain duration was also related to unsuccessful reduction of radiating leg pain.

Studies have shown that pain acceptance strategies related to psychological flexibility are important in the presence of chronic musculoskeletal pain. However, the predictors of these strategies have not been studied extensively in patients with whiplash-associated disorders (WAD). ⋯ For engagement in activities and pain acceptance, the fear of movement appears to emerge as the strongest predictor, but patients' perceived reactions from their spouses need to be considered in planning the management of WAD.
