OBJECTIVE The use of nerve transfers versus nerve grafting for neonatal brachial plexus palsy (NBPP) remains controversial. In adult brachial plexus injury, transfer of an ulnar fascicle to the biceps branch of the musculocutaneous nerve (Oberlin transfer) is reportedly superior to nerve grafting for restoration of elbow flexion. In pediatric patients with NBPP, recovery of elbow flexion and forearm supination is an indicator of resolved NBPP. Currently, limited evidence exists of outcomes for flexion and supination when comparing nerve transfer and nerve grafting for NBPP...

A number of orthopedic injuries can occur during epileptic seizures. Anterior shoulder dislocation is one such orthopedic injury that is quite rare. The shoulder dislocation may injure the brachial plexus. Besides seizures, the nerves can also be damaged by anticonvulsive therapy. Muscle wasting following a seizure can misguide a clinician to investigate only neural or muscular pathologies. We report here an individual with epilepsy who was referred to us for electrodiagnostic evaluation of proximal muscle wasting related to a suspected proximal neuropathy...

Perioperative peripheral nerve injury is a serious yet preventable perioperative complication. Since the inception of the American Association of Anesthesiologists Closed Claim Project, the incidence of peripheral nerve injury has remained constant with an overall reported prevalence rate of 15% to 16%. To date, the most frequent nerve injuries are ulnar nerve neuropathy and brachial plexus injury. This article will review the clinical presentation, pathophysiology, causative and risks factors, and preventive measures for the two most common nerve injuries...

AIM: The plexus brachialis is a complex structure with anatomical variations and connections with neighboring tissues. These variations may cause disparity in the motor and sensorial innervations of the upper extremity. The knowledge of anatomy and probable variations are important for performing surgical procedures in the neck, shoulder and axilla. This study was planned to demonstrate the anatomical variations of infantile brachial plexus. MATERIAL AND METHODS: A total of 20 plexus brachialis from 11 fetal cadavers were dissected and examined microscopically...

BACKGROUND: The C5-C6 nerve roots are usually spared from avulsion after brachial plexus injury (BPI) and thus can be used as donors for nerve grafting. To date, there are no appropriate animal models to evaluate spared nerve root stumps. Hence, the aim of this study was to establish and evaluate a rat model with spared nerve root stumps in BPI. NEW METHOD: In rupture group, the proximal parts of C5-T1 nerve roots were held with the surrounding muscles and the distal parts were pulled by a sudden force after the brachial plexus was fully exposed, and the results were compared with those of sham group...

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...

Phrenic nerve transfer has been a well-established procedure for restoring elbow flexion function in patients with brachial plexus avulsion injury. Concerning about probably detrimental respiratory effects brought by the operation, however, stirred up quite a bit of controversy. We present a case report of the successful application of phrenic nerve as donor to reinnervate the biceps in a septuagenarian with brachial plexus avulsion injury, not accompanied with significant clinical respiratory problem.

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...

In contrast to shoulder dislocations in younger patients, anterior shoulder dislocation in the elderly is often associated with concomitant injuries to the rotator cuff and fractures. There is also frequent involvement of the brachial plexus or peripheral nerves. After closed reduction and a short period of immobilization, physiotherapy should be performed to restore mobility and strength. The evaluation of the rotator cuff is essential for further treatment decisions. The majority of patients are classically treated conservatively...

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...

INTRODUCTION: Traumatic brachial plexus injury (BPI) can result in debilitating sequelae of the upper extremity. Presently, therapeutic decisions are based on the mechanism of injury, serial physical examination, electromyography, nerve conduction, and imaging studies. While magnetic resonance imaging is the current imaging modality of choice for BPI, ultrasound is a promising newcomer that is inexpensive, accessible, and available at point of care. OBJECTIVE: To evaluate ultrasound as a diagnostic tool in the assessment of traumatic adult BPI through a systematic review...

BACKGROUND: Functional recovery after peripheral nerve injury and repair is related with cortical reorganization. However, the mechanism of innervating dual targets by 1 donor nerve is largely unknown. OBJECTIVE: To investigate the cortical reorganization when the phrenic nerve simultaneously innervates the diaphragm and biceps. METHODS: Total brachial plexus (C5-T1) injury rats were repaired by phrenic nerve-musculocutaneous nerve transfer with end-to-side (n = 15) or end-to-end (n = 15) neurorrhaphy...

The close proximity of contraceptive implant placement to the course of the ulnar nerve can result in injury. Several factors have been implicated in this complication including: low BMI, erroneous placement of the implant, implantation over the brachial groove, and migration of the implant from its original insertion. Clinicians should familiarise themselves with the vulnerable neurovascular structures in the area and refer promptly to a specialist if any neurological symptoms develop during placement or removal of these devices...
