In a retrospective study, 1.173 fractures of the proximal femur, which had been treated surgically, were analysed in two periods from 1975 to 1991 and from 1992 to 2000. The influence on mortality of preoperative risk factors and primary treatment with total hip replacement (THR), even in cases of pertrochanteric fractures, was analysed by stepwise logistic(More)
Bone graft substitutes often exhibit poor bone regeneration in large defects because of inadequate vascularization. Studies have shown that if blood supply is compromised, application of osteogenic factors alone could not induce successful healing. This study was to evaluate the effects of vascular endothelial growth factor, which combined with a coralline(More)
Both platelet-rich plasma (PRP) and vascular endothelial growth factor (VEGF) can promote regeneration. The aim of this study was to compare the effects of these two elements on bone formation and vascularization in combination with bone marrow stromal cells (BMSC) in a critical-size bone defect in rabbits. The critical-size defects of the radius were(More)
Anterior cruciate ligament (ACL) is the most commonly injured knee ligament in sports-related activities, especially in pivoting sports. In general, knee joint movements about the off-axes are much more limited and musculoskeletal injuries are usually associated with excessive loading/movement about the off-axes. The purposes of this project were to develop(More)
PURPOSE Pivoting neuromuscular control and proprioceptive acuity may play an important role in anterior cruciate ligament injuries. The goal of this study was to investigate whether pivoting off-axis intensity adjustable neuromuscular control training (POINT) could improve pivoting neuromuscular control, proprioceptive acuity, and functional performance.

The goal of this study was to use an offaxis robotic elliptical trainer to improve off-axis neuromuscular control in people with knee injuries. Thirteen individuals with knee injuries participated in the study. Among them, 8 individuals participated in 18 sessions of pivoting offaxis intensity-adjustable neuromuscular control training (POINT) (3(More)
Females are at greater risks of musculoskeletal injuries than are males, which may be related to decreased neuromuscular control in axial and/or frontal planes, offaxis neuromuscular control. The objective of this study was to investigate gender differences in offaxis neuromuscular control during stepping under a slippery condition. Forty-three healthy(More)
Treatment by continuous passive movement at home is an alternative to immobilisation in a cast after surgery for club foot. Compliance with the recommended treatment, of at least four hours daily, is unknown. The duration of treatment was measured in 24 of 27 consecutive children with a mean age of 24 months (5 to 75) following posteromedial release for(More)
A retrospective analysis of 54 patients with paralytic scoliosis due to myelomeningocele, who underwent surgical treatment, was performed. The aim of this study was to compare different surgical techniques and to identify clinical parameters influencing primary and midterm results. Three surgical techniques were used: 1) group I, posterior(More)
The goal of this study was to investigate the efficacy of off-axis neuromuscular control training using a pivoting elliptical machine. Although knee motion is mainly in flexion/extension, injuries to the knee are usually associated with excessive off-axis movement (tibial axial rotation and valgus/varus). A pivoting elliptical training system was developed(More)
