Traction therapy is one of the most common conservative treatments for low back pain. However, the effects of traction therapy on lumbar spine biomechanics are not well known. We investigated biomechanical effects of two-step traction therapy, which consists of global axial traction and local decompression, on the lumbar spine using a validated three-dimensional finite element model of the lumb...

klippel-feil syndrome is known by the classic triad of shortness of the neck , limitation of neck movements, and a low posterior hairline. there are often accompanying cervical spinal abnormalities such as kyphoscoliosis as well as urogenital and cardiac abnormalities. presented here we have a 20 year old young man with hypoesthesia and decreased motor function in the right hand. the problem be...

The purpose of the present study was to determine the loads acting on the lumbar spine when traction therapy was given in the Fowler's position. The study had two parts: a theoretical analysis which showed that traction produced a flexion moment on the spine as well as axial distraction; and an experimental study which measured the flexion moment induced by the adoption of the Fowler's position...

This paper presents an exact solution and a finite element method (FEM) for a Piezoceramic Rod under static load. The cylindrical rod is made from polarized ceramics (piezoceramics) with axial poling. The lateral surface of the rod is traction-free and is unelectroded. The two end faces are under a uniform normal traction. Electrically, the two end faces are electroded with a circuit between th...

OBJECTIVES To discuss the pathophysiology of atlanto-axial subluxation as a rare complication of tonsillectomy, and to discuss the important radiological findings for diagnosis and treatment planning. CASE REPORT We report a case of post-tonsillectomy atlanto-axial subluxation, also known as Grisel's syndrome, in a child. On the third day after surgery, the boy presented with torticollis with...

This paper deals with the design of high power – low dimensions axial-flux permanent-magnet motor intended for traction application. First, two motor configurations are analytically designed and compared using finite element calculation. Then, the configuration yielding the best performances is integrated and modelled with the whole traction chain under MATLAB/SIMULINK environment in order to d...

Lisfranc fracture dislocations are an often misdiagnosed injury pattern, which if left unreduced can lead to signifi cant disability (1-5). The articulation between the bases of the 5 metatarsals, cuneiforms, and cuboid has been termed the Lisfranc joint (6, 7). Lisfranc joint represents a junction between the forefoot and the midfoot. Three functional columns make up the tarsometatarsal area, ...
