A hallmark of voluntary motor control is the ability to adjust motor patterns for novel mechanical or visuomotor contexts. Recent work has also highlighted the importance of feedback for voluntary control, leading to the hypothesis that feedback responses should adapt when we learn new motor skills. We tested this prediction with a novel paradigm requiring that human subjects adapt to a viscous...

ABSTRACT The aim of the study was to evaluate results of closed intramedullary nailing using Talwarkar square nails in adult forearm fractures. We prospectively evaluated 34 patients with both bone forearm fractures. The average time to union was 12.8 (SD +3.2) weeks with cast support for a mean of 8.2 weeks. Union was achieved in 31 out of 34 patients. Using the Grace and Eversmann rating syst...

The continuous accumulation of tailings in reservoirs not only causes environmental pollution but may also cause geological disasters. paste-filling mining method is an effective way to address the tailings, and it necessary study flow characteristics pipeline transportation process—a core process this method. However, limited by factors such as test conditions, equipment, cost, research field ...

PURPOSE Radiographic arthrosis is a common sequela of elbow trauma. Few studies have addressed risk factors for radiographic arthrosis after elbow injury, especially in the long term. Data from multiple long-term follow-up studies of patients with surgically treated elbow fractures provided us with an opportunity to assess risk factors for long-term radiographic arthrosis after elbow injury. ...

Four patients who had injured the lower end of the humerus in childhood with resulting cubitus varus developed recurrent posterior dislocation of the head of the radius after further injury to the elbow. Dislocation occurred when the forearm was supinated and spontaneous reduction took place on pronation. At operation the lateral ligament complex was seen to be lax and elongated. After tighteni...

Radial artery is one of the terminal branches of the brachial artery arising in the cubital fossa; the other being the ulnar artery. Radial artery usually begins in the cubital fossa about 1 cm below the bend of the elbow at the level of the neck of the radius just medial to the tendon of biceps brachii muscle, and terminates in the hand by forming the deep palmar arch after anastomosing with t...

The case is of 23-year-old Caucasian male who fell from 30 feet height in a suicidal attempt. He sustained multiple orthopedic fractures including hips, left lower ribs, and right radius at the elbow. He had multiple orthopedic surgeries with fixation of his fractures including pins, plates and screes. He presented to the hospital with fever, tachycardia, and malaise. He was discharged initiall...

INTRODUCTION It is well known that the biceps functions mainly as an elbow flexor and forearm supinator. In vivo elbow flexion and forearm supination strength testing after rupture of the long head of the biceps tendon has shown decreases of 0-16% and 0-21%, respectively [1,2]. Although many studies have attempted to identify the role of the long head of the biceps brachii muscle in elbow flexi...

The Essex-Lopresti injury of the forearm is difficult to diagnose. A missed diagnosis can lead to persistent pain and instability of the wrist. We report a 33-year-old man with a pre-existing cubital varus deformity who sustained an atypical Essex-Lopresti injury after a fall on his elbow. Accurate diagnosis requires understanding of force transmission and anatomy of the radius and ulna, as wel...
