Case Reports Comparative Study Clinical Trial
Axial symptoms after cervical laminoplasty with C3 laminectomy compared with conventional C3-C7 laminoplasty: a modified laminoplasty preserving the semispinalis cervicis inserted into axis.
Results of C4-C7 laminoplasty with C3 laminectomy and C3-C7 laminoplasty were compared. ⋯ This method was less invasive to the cervical posterior muscles than C3-C7 laminoplasty. This is an effective procedure for preventing postoperative axial symptoms.

Comparative Study
In vitro stabilizing effect of a transforaminal compared with two posterior lumbar interbody fusion cages.
An in vitro biomechanical flexibility test on different lumbar interbody fusion cages using monosegmental lumbar spine specimens. ⋯ In terms of its stabilizing effect, TLIF using the MOON cage can be recommended as an alternative to PLIF using the cubic Stryker cages. Compared with the threaded BAK PLIF cages, however, the MOON TLIF cage provides a lower primary stability in lateral bending, flexion, and extension.

Intermittent pneumatic compression stockings (IPC) alone were prospectively used to avoid deep venous thrombosis (DVT) and pulmonary embolism (PE) in 100 consecutive patients undergoing single-level anterior corpectomy/fusion (ACF) and in 100 patients having multilevel ACF/posterior fusion. ⋯ IPCs were as effective for prophylaxis against DVT/PE for 100 patients undergoing single-level ACF and for 100 having circumferential procedures as existing therapies (mini-heparin and low-dose heparin), without the risk of hemorrhage. However, the 1% and 2% respective rates of PE were comparable to frequencies of PE encountered in other cranial/spinal series using mini-heparin and/or low-dose heparin regimens but avoided the 2% to 4% risk of major postoperative hemorrhage.

Clinical Trial
The use of magnetic resonance imaging to evaluate lumbar muscle activity during trunk extension exercise at varying intensities.
Descriptive, repeated measures analysis of exercise-induced changes in lumbar muscle transverse relaxation time (T2). ⋯ Muscle functional MRI can be used to characterize lumbar muscle function during trunk extension exercise. The levels and recruitment patterns of the lumbar extensors, as measured by muscle T2 shifts, vary with exercise intensity. Future research is needed to assess the mechanism of the nonlinear relationship between T2 shifts and exercise intensity, and to clarify the effects of fatigue and the order of exercise presentation on the T2 response of the lumbar extensors.

Correlation between previously validated questionnaires. ⋯ As opposed to what has been shown in other cultural settings, FAB have virtually no clinical relevance in Spanish LBP patients who are treated in the National Health Service and who are in a potentially active working situation. The influence of FAB on disability is minimal and much less than that of pain severity, and their contribution to the patient's quality of life is irrelevant. Further studies should explore the potential value of FAB in other Latin-Mediterranean countries.
