Most transhumeral amputees report that their prosthetic device lacks functionality, citing the control strategy as a major limitation. Indeed, they are required to control several degrees of freedom with muscle groups primarily used for elbow actuation. As a result, most of them choose to have a one-degree-of-freedom myoelectric hand for grasping objects, a myoelectric wrist for pronation/supination, and a body-powered elbow. Unlike healthy upper limb movements, the prosthetic elbow joint angle, adjusted prior to the motion, is not involved in the overall upper limb movements, causing the rest of the body to compensate for the lack of mobility of the prosthesis...

Maisonneuve fractures are relatively well known in the sports medicine, and orthopedic communities, however, can be commonly missed among primary care providers. The following case outlines an active duty 35-yr-old female patient who presented with acute pain on the left ankle and lower leg after she misjudged a step. The injury is a combination of high fibular and medial malleolar fractures with a disruption of the tibiofibular syndesmosis ligaments. This is a result of extreme external rotation and pronation of a fixed foot...

BACKGROUND: In the classical conception, the brachioradialis is a forearm supinator. The hypothesis of this study was that, at least in certain positions of elbow flexion and forearm rotation, the brachioradialis is, along with the biceps and brachialis, one of the main elbow flexors. METHODS: Fifteen young healthy male volunteers participated in this research. The activities of the biceps, brachialis and brachioradialis muscles were studied using surface electromyography, while the subjects were performing elbow flexions/extensions with as much strength as possible, forearm in neutral position, then in full pronation, then in full supination...

We reconstructed three-dimensional images of radius and ulna in 38 forearms of 25 patients with congenital proximal radioulnar synostosis from their computed tomographic studies. We also analysed correlations between the deformities of radius and ulna and degrees of fixed pronation of these forearms. The average ulnar deviation, flexion and internal rotation deformities of the radius were 6°, 3° and 18°, respectively. The average radial deviation, extension and internal rotation deformities of the ulna were 3°, 4° and 30°, respectively...

REVIEW
R D Blossey, C Krettek, E Liodakis
Forearm fractures are common in all age groups. Even if the adjacent joints are not directly involved, these fractures have an intra-articular character. One of the most common complications of these injuries is a painful limitation of the range of motion and especially of pronation and supination. This is often due to an underdiagnosed torsional deformity; however, in recent years new methods have been developed to make these torsional differences visible and quantifiable through the use of sectional imaging...

Recently, wearable pressure sensors have attracted tremendous attentions because of their potential applications in monitoring physiological signals for human healthcare. The sensitivity and linearity are the two most essential parameters to pressure sensors. Although various designed micro/nano-structure morphologies introduced, the trade-off between sensitivity and linearity can not be well balanced. The human skin that contains force receptors in reticular layer owns high sensitivity even for large external stimulus...
