Review
Is there a rational basis for post-surgical lifting restrictions? 2. Possible scientific approach.
Lifting restrictions postoperatively are quite common but there appears to be little scientific basis for them. Lifting restricitions are inhibitory in terms of return to work and may be a factor in chronicity. The mean changes in functional spinal motion unit (FSU) stiffness with in vitro or computer-simulated discectomies, facetectomies and laminectomies were reviewed from the literature. ⋯ The adjusted NIOSH guidelines provide a reasonable way to estimate weight restrictions and accomodations such as lifting aids. Such resitrictions should be as liberal as possible so as to facilitate, not prevent, return to work. Patients need more advice regarding lifting activities and clinicians should be more knowledgeable about the working conditions and constraints of a given workplace to effectively match the solution to the patient's condition.

Comparative Study Clinical Trial
Treatment of idiopathic scoliosis with side-shift therapy: an initial comparison with a brace treatment historical cohort.
A group of 44 patients with idiopathic scoliosis (mean age 13.6 years) with an initial Cobb angle between 20 degrees and 32 degrees received side-shift therapy (mean treatment duration 2.2 years). A group of 120 brace patients (mean age 13.6 years) with an initial Cobb angle in the same range (mean brace treatment 3.0 years) was the historical reference group. ⋯ The difference in the mean progression of the Cobb angle for the respective groups is small (for efficiency: 3 degrees vs -2 degrees, for efficacy: 2 degrees vs -1 degrees ). Side-shift therapy appears to be a promising additional treatment for idiopathic scoliosis in adolescents with an initial Cobb angle between 20 degrees and 32 degrees.

To evaluate the effect of brace treatment on self-image in patients with adolescent idiopathic scoliosis, 54 consecutive patients admitted for brace treatment were interviewed before bracing. A prevalidated questionnaire including the following five aspects of self-image was used: (1) body-image, (2) self-perception of skills and talents, (3) emotional well-being, (4) relations with family, and (5) relations with others. As a control group, the answers of 3465 normal school children were used. ⋯ Neither were there any statistically significant differences between the answers of the scoliosis patients in the pre-bracing and follow-up interviews. This was valid for the total score as well as for each subscale item score. It is concluded that wearing the brace does not affect the self-image of adolescents with idiopathic scoliosis negatively.

The purpose of this combined study was to evaluate the stability and safety of a new monocortical screw-plate system for anterior cervical fusion and plating (ACFP) according to Caspar in comparison with classical bicortical fixation. In the biomechanical part of the study two groups, each comprising six fresh human cadaveric spines (C4-C7), matched for bone mineral density, additionally resulting in almost the same mean age, were used. Range of motion and neutral zone were analyzed in flexion-extension, rotation (left, right) and lateral bending (left, right) using pure moments of +/- 2.5 Nm for each specimen in the intact state, after discectomy at C5/6 and after discectomy at C 5/6 followed by bone grafting plus plating (Caspar plates), with either monocortical or bicortical screws. ⋯ Following these findings monocortical screw fixation can be recommended for the majority of anterior cervical fusion and plating procedures in degenerative disease, making the procedure quicker, easier, and safer. Bicortical screw fixation still has specific indications for multilevel stabilization, poor bone quality (osteoporosis, rheumatoid disease - as bicortical oversized rescue screw), unstable spines (trauma, tumour) and in particular for the realignment of kyphotic deformities (restoration of the normal lordotic curve). Due to the design of the study the results apply only to surgical treatment of monosegmental degenerative disc disease at the time.
