Axillary nerve injury is common after brachial plexus injuries, particularly with shoulder luxation. Nerve grafting is the traditional procedure for postganglionic injuries. Nerve transfer is emerging as a viable option particularly in late referrals. At the proximal arm the radial and axillary nerves lie close by. Sacrificing one of the triceps muscle nerve branches induces little negative consequences. Transferring the long head of the triceps nerve branch is a good option to recover axillary nerve function...

BACKGROUND: Root avulsion to all 5 roots of the brachial plexus is a common presentation and keeps a major reconstructive challenge. The contralateral C7 (CC7) nerve transfer has been used in treating brachial plexus avulsion injury (BPAI) since 1986. However, the effectiveness of the procedure remains a subject of controversy. The aim of this meta-analysis was to study surgical outcomes regarding motor and sensory recovery after CC7 nerve transfer. METHODS: Chinese or English (i...

REVIEW
Gerard Chang, Asif M Ilyas
Radial nerve palsies are a common complication associated with humeral shaft fractures. The authors propose classifying these injuries into 4 types based on intraoperative findings: type 1 stretch/neuropraxia, type 2 incarcerated, type 3 partial transection, and type 4 complete transection. The initial management of radial nerve palsies associated with closed fractures of the humerus remains a controversial topic, with early exploration reserved for open fractures, fractures that cannot achieve an adequate closed reduction requiring fracture repair, fractures with associated vascular injuries, and polytrauma patients...

PURPOSE: The radial nerve appears to be more vulnerable to injury in the brachium than the median and ulnar nerves. The underlying mechanism for this increased vulnerability is not well explained. We hypothesize that the radial nerve has less excursion than the median and ulnar nerves because it is anatomically tethered by the lateral intermuscular septum (LIS) and that elbow positioning and LIS release will improve its excursion. METHODS: Eight paired fresh-frozen cadaveric upper extremity specimens were used...

Humeral periprosthetic fractures are a challenging problem and their occurrence has increased, particularly over the last decade. The role of cerclage wires or cables in these fractures includes revisions with longer stems, and augmentation of a plate osteosynthesis in which the stem does not allow additional screw placement or structural bone grafts as supplementary fixation. These procedures are demanding because of the proximity of the radial nerve within the operating field. Placing a cerclage wire or cable around the fractured fragments offers a simple and safe procedure to avoid radial nerve injury or palsy in the treatment of complex humeral shaft fractures...

INTRODUCTION: Generally, anatomical reduction of shaft fractures through operative treatment is necessary to restore the anatomical relationship of the forearm bones. However, a number of nerves and vessels are located in the proximal radius, which complicates surgery. In this study, we aimed to reduce postoperative complications by using a posterior approach. PRESENTATION OF CASE: We describe an isolated fracture through the radial bicipital tuberosity in a 69-year-old man caused by direct blunt force and our management of the fracture...

OBJECTIVES: Patients with C5 and C6 nerve root avulsion may complain from pain. For these patients, end-to-side nerve transfer of the superficial radial nerve into the median nerve is suggested to relieve pain. PATIENTS AND METHODS: Eleven patients (with a primary brachial plexus reconstruction) undergoing end-to-side nerve transfer of the superficial radial nerve into the ulnovolar part of the median nerve were assessed. Pain before surgery was compared to that at 6-month follow-up using visual analog scale (VAS) scores...

BACKGROUND: The treatment of radial nerve palsy caused by closed humeral shaft fracture is a matter of debate. The purpose of this study is to evaluate the outcome of early surgical management of radial nerve palsy in patients with unstable closed humeral shaft fractures and to determine whether patients with this injury should be surgically explored. METHODS: Medical records of 15 consecutive patients who had undergone open reduction and internal fixation for unstable closed humeral shaft fractures were reviewed...

BACKGROUND: Injury to distal of posterior cord of brachial plexus leads to palsy of the radial and axillary nerves. The symptoms are usually motor deficits of the deltoid muscle, triceps brachii muscle, and the extensor muscles of the wrist, thumb and fingers. Tendon transfers, nerve grafts, and nerve transfers are options of surgical treatment of proximal radial nerve palsy to restore some motor functions. Tendon transfer is painful, requires a long immobilization, and decreases donor muscle strength; nevertheless, nerve transfer produces promising outcome...

Direct posterior and posterolateral portals are the standard portals used in posterior elbow arthroscopy. A posteromedial portal in the elbow is not recommended because of its proximity to the ulnar nerve. However, iatrogenic injuries to the ulnar nerve have been reported after elbow arthroscopy using the standard posterior portals, especially in posteromedial elbow joint pathologies. We present a surgical technique applicable to posteromedial elbow pathology by using ultrasound-assisted posteromedial portal placement of the elbow joint...

BACKGROUND: Radial nerve injury is a rare but clinically significant complication of revision shoulder arthroplasty and fixation of native and periprosthetic proximal humeral fractures. Understanding of the anatomic relationship between the radial nerve as it enters the humeral spiral groove and anterior shoulder landmarks in a deltopectoral approach is necessary to avoid iatrogenic radial nerve injury. METHODS: Eight forequarter cadaveric specimens were dissected through a deltopectoral approach...
