Pain at the front of the radial side of the wrist or at the base of the thenar eminence is a common complaint. Conditions such as osteoarthritis of the first carpo-metacarpal joint, ununited fractures of the scaphoid bone and ganglia at the front of the wrist are easily recognised but the diagnosis may not be straightforward. Since 1952 we have operated on twelve patients who had pain from vari...

The aim of this study was to assess the muscle functional connectivity obtained from surface electromyogram (SEMG) during unilateral and bilateral texting on a smart-phone as well as standard text entry on a personal computer. Fourteen healthy adults participated in the study. The SEMG signals from the left and right proximal: cervical erector spinae, upper trapezius, lower trapezius and distal...

BACKGROUND Previous studies have indicated that the demands placed on the medial ulnar collateral ligament of the elbow when it is subjected to valgus torque during throwing exceed its failure strength, which suggests the necessary dynamic contribution of muscle forces. We hypothesized that the flexor-pronator mass assists the medial ulnar collateral ligament in stabilizing the elbow against va...

Mountain bikers often report impaired finger sensitivity caused by mechanical vibrations and misalignment between the wrist forearm when using traditional (cylindrical) handles. The aim of this study was to evaluate acute effects ergonomic clip-on handles that allowed hand rest on medial carpal bone, muscular activity, vibration transmissibility cycle ergometer body segments, handgrip strength....

Spasticity is one of the common complications in upper motor neuron lesions and without appropriate treatment it causes disturbances in movement pattern. Assessments of patients are effective in patient's management. Modified Ashworth scale (MAS) is one of the criteria in qualitative assessment of spasticity, and there are lots of controversies about its validity. The purpose of this study is t...

Volar fixation of dorsally unstable distal radius fractures is a new method of treatment that provides the benefits of stable internal fixation without the complications of the dorsal approach. A new, fixed-angle fixation device, the distal volar radius (DVR) plate, (Fig. 1) has been introduced for this purpose. Experience gained by applying this technique to clinically complex cases led us to ...

BACKGROUND Tendinopathy of the flexor carpi ulnaris tendon is a rare entity. Recent research revealed the role of a neurovascular ingrowth at the point of pain in various tendinopathic locations, such as at the Achilles and patellar tendon, in plantar fasciitis as well as in supraspinatus and tennis elbow tendinopathy. However, beyond the elbow no such neovascularisation has been reported to da...

The neural control of the clasp reflex in male Xenopus laevis has been studied by using anatomical, electrophysiological, and biochemical techniques. Neurons in spinal segment 2 of castrated males accumulate label after injection of [3H]-dihydrotestosterone; these neurons are distributed within the rostral portions of the motoneuronal pools of the sternoradialis and flexor carpi radialis muscle...

In 28 patients with a solitary diagnosis of instability of the trapeziometacarpal joint because of a rupture of the anterior oblique ligament, reconstruction was carried out using a slip of the tendon of flexor carpi radialis. We were able to review 26 patients. The results after a follow-up of four years seven months showed that most (87%) had significant relief from pain and symptoms. Sevente...
