background: palmaris longus (pl) is a muscle with marked variations. it is harvested as a tendon graft in many surgical proceduresin which a certain length of tendon is required. the aims of the present study were to determine the variations of this tendon in iranian population and to find whether the length of pl tendon could be estimated by measuring the forearm length and height.   methods: ...

background there is considerable variation in the treatment of distal forearm torus fractures (dftf), from soft bandaging to cast immobilization. objectives the present study aimed to show the result of removable wrist splint (rws) in the treatment of these fractures. materials and methods one hundred forty two children aged less than 17 years old with dftf were studied prospectively. these pat...

The continuous passive motion (CPM) device we developed for the elbow joint implements pro-supination of the forearm naturally accompanying flexion and extension of the elbow joint. As the method of making the curative effect due to accompanying pro-supination clear, the range of motion (ROM) of the forearm skeleton are estimated by using of the prosupination model of the forearm skeleton. As t...

In a prospective cohort study, the association between maternal vitamin D status during pregnancy and offspring forearm fractures during childhood and adolescence was analysed in 30 132 mother and child pairs recruited to the Danish National Birth Cohort between 1996 and 2002. Data on characteristics, dietary factors and lifestyle factors were collected on several occasions during pregnancy. We...

This study was undertaken to try to define the best clinical predictors of forearm fractures in children aged 3 to 15 years. Over an 8-month period, 136 children attending the Accident and Emergency Department of the Mater Infirmorum Hospital were enrolled in the study and 67 fractures were diagnosed. Gross deformity, point tenderness and decrease in supination and pronation movements of the fo...

BACKGROUND Access-related problems are one of the major causes of morbidity in elderly patients with chronic kidney disease. The aim of this study was to assess potential risks and benefits in elderly patients comparing forearm arteriovenous fistula (AVF) and perforating vein AVF below the elbow for primary vascular access. METHODS A retrospective comparison of elderly patients (65.7 ± 9.3 ye...

Control of skin blood flow (SkBF) is on the efferent arm of both thermoregulatory and nonthermoregulatory reflexes. To what extent aging may affect the SkBF response when these two reflex systems interact is unknown. To determine the response of aged skin to the unloading of baroreceptors in thermoneutral, cold stress, and heat stress conditions, sequential bouts of nonhypotensive lower body ne...

AIMS To investigate the use of a worker based methodology to assess the physical stresses of lifting tasks on effort expended, and to associate this loading with musculoskeletal outcomes (MO). METHODS A cross sectional study was conducted on 217 male manual handling workers from the Hong Kong area. The effects of four lifting variables (weight of load, horizontal distance, twisting angle, and...

In hypercholesterolemia, impaired nitric oxide activity has been associated with increased nitric oxide degradation by oxygen radicals. Deficiency of tetrahydrobiopterin, an essential cofactor of nitric oxide synthase, causes both impaired nitric oxide activity and increased oxygen radical formation. In this study we tested whether tetrahydrobiopterin deficiency contributes to the decreased nit...
