Thirty-five patients who sustained humeral shaft fractures were treated by open reduction internal fixation using AO techniques between 1992 and 1997. Open fractures occurred in 8 patients. Primary radial nerve palsy was present in 5 cases. In 16 patients an open fracture or multiple trauma, or both were indications for surgery. Eight osteosynthesis were performed after failed conservative trea...

Radial neuropathy is frequently associated with fracture of the middle third of the humerus owing to the course of the nerve adjacent to the humeral shaft. The prevalence varies from 2 to 18% of humeral fractures. The therapeutic management is still controversial. Some authors recommend initial surgical exploration, whereas others prefer observation and intervention only if the injured nerve fa...

Pain in the lateral compartment of the elbow joint and decreased strength of the extensor muscle constitute a fairly common clinical problem. These symptoms, occurring in such movements as inverting and converting the forearm, pushing, lifting and pulling, mostly affect people who carry out daily activities with an intense use of wrist, e.g. work on computer. Strains in this area often result f...

The radial nerve is at risk of injury during surgical approaches to the humeral shaft. Previous authors have described an anterolateral approach to the humerus limited by the radial nerve, requiring that distal dissection be carried anterior into a neurovascularly crowded interval. A novel extensile approach is described using a neuromuscular bridge to protect the radial nerve, thus enabling sa...

Although usually omitted in the description of nerve injuries in the newborn, radial nerve palsies are not infrequent. The cause of the paralysis is not clear but the occasional coincidental finding of a patch of subcutaneous fat necrosis over the course of the radial nerve (Lightwood, 1951) suggests the possibility of direct trauma to the nerve. That the injury is not uncommon is supported by ...

INTRODUCTION Radial nerve compression by a ganglion in the radial tunnel is not common. Compressive neuropathies of the radial nerve in the radial tunnel can occur anywhere along the course of the nerve and may lead to various clinical manifestations, depending on which branch is involved. We present two unusual cases of ganglions located in the radial tunnel and requiring surgical excision. ...

INTRODUCTION We report an extremely rare case of tardy posterior interosseous nerve palsy that developed 40 years after unreduced anterior dislocation of the radial head in a Monteggia fracture. CASE PRESENTATION A 46-year-old Asian woman was diagnosed with tardy posterior interosseous nerve palsy resulting from residual dislocation of the radial head in a Monteggia fracture. The patient reme...

The subumbrella of the hydrozoan jellyfish Aequorea victoria (previously classified as Aequorea aequorea) is divided by numerous radial canals and attached gonads, so the subumbrellar musculature is partitioned into subumbrellar segments. The ectoderm of each segment includes two types of muscle: smooth muscle with a radial orientation, used for local (feeding and righting) and widespread (prot...
