Randomized Controlled Trial Multicenter Study Comparative Study
Adjacent level degeneration and facet arthropathy after disc prosthesis surgery or rehabilitation in patients with chronic low back pain and degenerative disc: second report of a randomized study.
Randomized clinical trial with 2-year follow-up. ⋯ In this first study that compared the courses of degeneration after treatment with disc prosthesis surgery or rehabilitation, ALD was observed at similar frequencies at the 2-year follow-up. However, the surgery group had increased FA at the implant level.

Randomized Controlled Trial Comparative Study
Specific trunk and general exercise elicit similar changes in anticipatory postural adjustments in patients with chronic low back pain: a randomized controlled trial.
A randomized controlled trial. ⋯ SEG elicited significant reductions in self-rated disability and pain, whereas similar between-group changes in trunk muscle onsets were observed. The motor control adaptation seems to reflect a strategy of improved coordination between the trunk muscles with the unilateral shoulder movement. Trunk muscle onsets during rapid limb movement do not seem to be a valid mechanism of action for specific trunk exercise rehabilitation programs.

Multicenter Study
Radiographical risk factors for major intraoperative blood loss during laminoplasty in patients with ossification of the posterior longitudinal ligament.
A retrospective multi-institutional study. ⋯ Laminoplasty for OPLL is associated with a risk of major intraoperative blood loss, which can potentially give rise to devastating postoperative complications. An occupying ratio of 60% or greater is a risk factor for major blood loss during laminoplasty in patients with OPLL.

A retrospective clinical study of scoliosis-associated airflow obstruction due to endothoracic vertebral hump. ⋯ Each patient with symptomatic scoliosis and thoracogenic scoliosis required relatively long periods of respiration management. Patients having lordoscoliosis with an apex located between T7 and T9 may develop airflow obstruction due to an endothoracic vertebral hump. Correction of lordoscoliosis through anterior and posterior approaches successfully improved endothoracic hump ratio and atelectasis in all patients.

A series study of patients with lower cervical facet dislocation accompanied by traumatic disc herniation treated with anterior decompression and nonstructural bone grafting and posterior fixation. ⋯ Although further study based on injury types as well as long-term follow-up is still needed, anterior decompression and nonstructural bone grafting and posterior fixation provides a promising surgical option for treating cervical facet dislocation with traumatic disc herniation.
