AIM To evaluate Bryant traction at home in terms of feasibility, morbidity, effect on length of hospital stay, outcome and costs. PATIENTS AND METHODS Retrospective analysis of 54 children treated for femoral shaft fracture (1991-2004). Results of 'home traction' (A, n=38) and 'hospital traction' (B, n=16) were compared. Data were collected regarding demographics, length of hospital stay, tra...

Traction folliculitis is a component of traction alopecia syndrome and has received minimal attention in primary source medical literature. The popularity of hairstyles that produce hair traction and the knowledge that early intervention improves prognosis amplify the importance of recognizing this entity. Traction folliculitis presents as perifollicular erythema and pustules on the scalp in ar...

Introduction: Bilateral hip dislocation (especially asymmetric type) occurs rarely. By review of literature (published since 1951 till 2004), we found 15 cases of bilateral asymmetric hip dislocation (age between 3 and 36 years) that contained 12 cases in males.  All of the patients were treated using closed reduction and then traction. There was no considerable difference between the results o...

bending analysis of multilayer graphene sheets (mlgss) subjected to non-uniform shear and normal tractions is presented. the constitutive relations are considered to be non-classical based on nonlocal theory of elasticity. based on the differential transformation method, numerical illustrations are carried out for circular and annular geometries. the effects of nano scale parameter, radius of c...

Recently, Permanent Magnet Synchronous Motors (PMSMs) have been widely accepted and employed in traction and railway transportation applications due to their various advantages such as small inertia, high efficiency and high torque density. In this paper, in order to use these motors as traction drives in an effective way, the vector control scheme is employed. In this strategy, the stator curr...

Plint (IMechE 182 (1):300–306,1967) reported a reduced coefficient of friction with increasing roller sizes in EHL traction measurements. In this study, similar scale effect has been observed when comparing measured curves at the same operating conditions between ball-on-disc rig and twin-disc machine different geometrical sizes. This studied numerically for point contacts radii curvature Rx ba...
