The motion of the current prostheses is sequential and does not allow natural movements. In this work, complex natural motion patterns from a healthy upper limb were characterized in order to be emulated for a trans-humeral prosthesis with three degrees of freedom at the elbow. Firstly, it was necessary to define the prosthesis workspace, which means to establish a relationship using an artific...

The posttraumatic proximal cross-union of the forearm in childhood is a rare complication after radial head, neck or proximal forearm fractures and elbow dislocations. There is no standardized treatment. Several surgical procedures with or without interposition techniques are described in the literature. The aim of this study was to analyze all children with cross-unions who underwent surgery o...

Introduction Usually the ulnar artery arises as one of the two terminal branches of brachial artery in the cubital fossa, which in turn gives rise to common interosseous artery in the upper forearm. Ulnar artery continues as superficial palmar arch in the hand by joining with superficial palmar branch of radial artery [1]. The term superficial ulnar artery is given when it arises from axillary ...

BACKGROUND This study investigated the quality of life of Chinese patients with malignant tumors who had undergone immediate free flap reconstruction surgery. In addition, we compared 2 groups of patients: those who had received radial forearm free flap surgery and others who had received free anterolateral thigh perforator flap surgery. METHODS Quality of life was assessed using the Medical ...

Reconstruction of the interosseous membrane is an emerging procedure designed to help restore anatomic and biomechanical relationships within the forearm after a longitudinal instability injury. The indication for this reconstruction is proven acute or chronic longitudinal instability of the forearm. This technique uses a synthetic braided graft tied over endobuttons at radial and ulnar tunnels...

INTRODUCTION Traumatic dislocation of the radial head in paediatric population is a well described injury, it is usually associated with an injury to the ulna in the Monteggia lesion (1), but can occur as an isolated injury also (2,3). CASE REPORT A 4.5 year old girl presented to emergency department with her right upper limb held in pronation and flexion following isolated closed injury. Roe...

Introduction Brachial artery is the continuation of axillary artery at the lower border of teres major muscle. It gives profunda brachii, nutrient artery to humerus, superior and inferior ulnar collateral arteries and muscular branches in the arm. It ends by dividing into radial and ulnar arteries at the neck of radius. Radial and ulnar arteries descend in the forearm pursuing a typical course ...

Abstract Introduction Double injury patterns in the form of Monteggia or Galeazzi fracture dislocation represent a spectrum of forearm injuries which are severe and usually necessitate operative intervention. Association of ulnar dislocation with proximal radioulnar disruption with fracture of the radial shaft, without dislocation of radiohumeral joint, represents a rare and unusual double inju...

Instruction: Measurement of brachial artery diameter variation by ultrasound methods has commonly been used to test the endothelial function. It is known that the artery diameter is increased by flow stimulation. Therefore in the present study, the effect of external obstruction, as flow stimulation, on the radial strain of the brachial artery was assessed. Also the biomechanical behavior of th...

PURPOSE Radial tunnel syndrome refers to pain on the lateral aspect of the forearm as a result of compression of the posterior interosseous nerve within a tunnel with specific anatomical boundaries. Diagnosis of the condition is difficult because of its close association with lateral epicondylitis, which warrants different methods of treatment. Based on a cadaveric study, a new clinical test, t...
