Are there benefits of a 2D gait analysis in the evaluation of the subtalar extra-articular screw arthroereisis? Short-term investigation in children.
A juvenile flexible flatfoot is a common abnormality during growth. For children with a pathological manifestation, subtalar extra-articular screw arthroereisis is a popular operative technique. Although this minimally invasive operation technique has been performed for >45 years, complications still occasionally occur. For this reason, we created this pilot study to investigate whether a two-dimensional (2D) gait analysis is able to identify functional movement deficits after surgery. ⋯ By means of the 2D gait analysis, we were able to show functional improvement after subtalar extra-articular screw arthroereisis. Nonetheless, we identified a few children who still had functional abnormalities. Certainly, it is unclear whether this additional examination is able to reveal all complications that would have occurred later.

Randomized Controlled TrialEffects of myofascial release in erector spinae myoelectric activity and lumbar spine kinematics in non-specific chronic low back pain: Randomized controlled trial.
Flexion-relaxation response of the lumbar erector spinae has been previously studied after different interventions such as exercise programs or spinal manipulation, in subjects with chronic low back pain. The objective of the study was to investigate the effects of an isolated myofascial release protocol on erector spinae myoelectric activity and lumbar spine kinematics in chronic low back pain. ⋯ The myofascial release protocol contributed to the normalization of the flexion- relaxation response in individuals who did not show myoelectric silence before the intervention, and also showed a significant reduction in pain and disability compared with the sham group.

Screws with larger core diameter and lower thread pitch increase the stability of locked plating in osteoporotic proximal humeral fractures.
Little is known about the screw design as a factor for stability of the bone-implant interface in locking plate fixation of proximal humeral fractures. Aim of the present study was to analyze if locking screws with a large core diameter and a low thread pitch provide increased stability when compared to conventional locking screws. ⋯ Controlled laboratory study.
