PURPOSE To evaluate the proximity to the radial nerve on cadaveric specimens of 2 modified anterolateral portals used for elbow arthroscopy. METHODS Ten fresh cadaveric elbow specimens were prepared. Four-millimeter Steinman pins were inserted into 3 anterolateral portal sites in relation to the lateral epicondyle: (1) the standard distal anterolateral portal, (2) a modified direct anterolate...

The authors report their experience with the posteromedial surgical approach of the humeral shaft for internal fixation of fractures by plating. Sixteen patients were treated for humeral shaft fractures (14 for recent fractures and two for nonunion) below the mid-diaphysis, all without injury of the radial nerve. Patients were operated in the prone position. Plate and screw fixation on the medi...

INTRODUCTION This study focuses on an anatomic variation in which the lateral antebrachial cutaneous nerve (LACN) innervates the radial border of the dorsum of the hand and thumb in addition to, or replacing, the superficial radial nerve (RSN). Here, we propose a technique of nerve conduction that identifies this variation. METHODS We studied nerve conduction in 200 upper limbs of two series ...

T he radial nerve is the most frequently injured of the three major peripheral nerves in the upper extremity.u It is most vulnerable to injury at the mid-humeral level, since it lies superficially and wraps around the spiral groove of the humerus. The most common causes of radial palsy are fractures of the humerus, elbow dislocations, and Monteggia fracture-dislocations. Barton states that one ...

BACKGROUND Peripheral nerve injury and brachial plexopathy are known, though rare complications of coronary artery surgery. The ulnar nerve is most frequently affected, whereas radial nerve lesions are much less common accounting for only 3% of such intraoperative injuries. CASE PRESENTATIONS Two 52- and 50-year-old men underwent coronary artery surgery. On the first postoperative day they bo...

BACKGROUND The criteria and timing for nerve surgery in infants with obstetric brachial plexopathy remain controversial. Our aim was to develop a new method for early prognostic assessment to assist this decision process. METHODS Fifty-four patients with unilateral obstetric brachial plexopathy who were ten to sixty days old underwent bilateral motor-nerve-conduction studies of the axillary, ...

background:  the purpose of this study was to report the preoperative complaints and postoperative outcome of patients after removal of the radial head prosthesis.   methods:  this is a retrospective review of 14 adult patients (6 females and 8 males) from 2007 to 2011, who underwent radial head prosthesis removal by three surgeons. the average time between implantation and removal was 23 month...

The radial nerve is the major nerve serving the extensor compartment of the arm. This article describes the anatomic features, clinical features based on lesion location, electrodiagnostic assessment, prognosis, and treatment of radial neuropathies. Numerous traumatic causes have been reported to result in radial neuropathies, including compression or stretch injury, surgical insult, or trauma....

Radial nerve palsy, either axonotmesis or neurapraxia, associated with fractures of the shaft humerus occurred in about 10 percent of the patients with humeral shaft fractures [1,2,3]. Its close relation to the humerus, especially fractures of the middle and the distal thirds of the humerus makes the radial nerve vulnerable to such injuries [4,5,6]. There are many debate about the management of...

BACKGROUND Damage to the radial nerve in the arm during revision of total elbow arthroplasty is a serious complication; which is still not well documented. The aim of this study was to define a way on how to avoid this complication and to prevent it. PATIENTS AND METHODS Four patients underwent radial palsy after revision of total elbow arthroplasty. An anatomical study on 20 upper limbs was ...
