Anterior tibial artery is a nonvital artery which is one of the three arteries of the leg. This artery has a short proximal l segment in the popliteal region and a long segment in the anterior compartment of the leg designated as distal segment. With consideration of the deep location of the proximal segment in the popliteal fossa, it is less susceptible to trauma and subsequent formation of an aneurysm. On the contrary, the superficial long distal segment is more susceptible to trauma with high chance of pseudoaneurysm formation at the site of unrecognized injury...

This study investigated the biomechanical responses of neonatal piglet brachial plexus (BP) segments-root/trunk, chord, and nerve at two different rates, 0.01 mm/second (quasistatic) and 10 mm/second (dynamic)-and compared their response to another peripheral nerve (tibial). Comparisons of mechanical responses at two different rates reported a significantly higher maximum load, maximum stress, and Young's modulus (E) values when subjected to dynamic rate. Among various BP segments, maximum stress was significantly higher in the nerve segments, followed by chord and then the root/trunk segments except no differences between chord and root/trunk segments at quasistatic rate...

Thoracic outlet syndrome (TOS) is caused by compression of the brachial plexus and/or subclavian vessels as they pass through the cervicothoracobrachial region, exiting the chest. There are three main types of TOS: neurogenic TOS, arterial TOS, and venous TOS. Neurogenic TOS accounts for approximately 95% of all cases, and it is usually caused by physical trauma (posttraumatic etiology), chronic repetitive motion (functional etiology), or bone or muscle anomalies (congenital etiology). We present two cases in which neurogenic TOS was elicited by vascular compression of the inferior portion of the brachial plexus...

Background  In rare, selected cases of severe (extended) upper obstetric brachial plexus palsy (OBPP), after supraclavicular exposure and distal mobilization of the traumatized trunks and careful neuroma excision, we decided to perform direct nerve coaptation with tolerable tension and immobilized the affected arm positioned in adduction and 90-degree elbow flexion for three weeks. Objectives  We present our surgical technique and preliminary results in a prospective open patient series, including 22 patients (14 right and 8 left side affected) between 2009 and 2016, operated at a mean age of 8...

Peripheral nerve injuries and brachial plexus injuries are relatively frequent. Significance of these injuries lies in the fact that the majority of patients with these types of injuries constitute working population. Since these injuries may create disability, they present substantial socioeconomic problem nowadays. This article will present current state-of-the-art achievements of minimal invasive brachial plexus and peripheral nerve surgery. It is considered that the age of the patient, the mechanism of the injury, and the associated vascular and soft-tissue injuries are factors that primarily influence the extent of recovery of the injured nerve...

This review summarizes the role of melatonin (MLT) in defense against toxic-free radicals and its novel effects in the development of the nervous system, and the effect of endogenously produced and exogenously administered MLT in reducing the degree of tissue and nerve injuries. MLT was recently reported to be an effective free radical scavenger and antioxidant. Since endogenous MLT levels fall significantly in senility, these findings imply that the loss of this antioxidant could contribute to the incidence or severity of some age-related neurodegenerative diseases...

Neurofibromas are benign peripheral nerve sheath tumors that occur commonly in individuals with neurocutaneous disorders such as neurofibromatosis type 1. Vagal nerve neurofibromas, however, are a relatively rare occurrence. We present the case of a 22-year-old man with neurofibromatosis type 1 with a neurofibroma of the left cervical vagal nerve. The mass was resected through an anterior approach without major event. In the postoperative course, the patient developed left vocal cord paralysis treated with medialization with injectable gel...

Background The reported incidence of brachial plexus birth injury (BPBI) is 0.87 to 2.2 per 1,000 live births. The psychological functioning, including self-concept and emotional-behavioral functioning, of children with BPBI has only been examined to a limited extent. Objective The purpose of this study was to describe the self-concept and emotional-behavioral functioning in children with BPBI from both the child's and parent's perspective. Methods Thirty-one children with BPBI, mean age 11 years 1 month, completed the Draw A Person: Screening Procedure for Emotional Disturbance (DAP:SPED) and Piers Harris Children's Self-Concept Scale (PHCSCS)...

We present the case of a venous malformation (VM) masquerading as a schwannoma. VMs are thin-walled vascular dilations of various sizes that typically present as soft, compressible, blue masses that are associated with pain or dysesthesia. VMs are commonly found in the head and neck as well as the distal extremities. Notably, slow-flow VMs are hypointense on T1-weighted imaging, hyperintense on T2-weighted imaging, and enhance markedly with contrast. However, VMs tend to be poorly circumscribed and fraught with venous lakes and phleboliths...

Background  Our previous experiments demonstrated modulation of the amplitude of the axonal compound action potential (CAP) by electrical stimulation. To verify assumption that glutamate released from axons could be involved in this phenomenon, the modification of the axonal CAP induced by glutamate was investigated. Objectives  The major objective of this research is to verify the hypothesis that axonal activity would trigger the release of glutamate, which in turn would interact with specific axonal receptors modifying the amplitude of the action potential...

Rationale  Knowledge of the relationship of the dorsal scapular artery (DSA) with the brachial plexus is limited. Objective  We report a case of a variant DSA path, and revisit DSA origins and under-investigated relationship with the plexus in cadavers. Methods  The DSA was examined in a male patient and 106 cadavers. Results  In the case, we observed an unusual DSA compressing the lower plexus trunk, that resulted in intermittent radiating pain and paresthesia. In the cadavers, the DSA originated most commonly from the subclavian artery (71%), with 35% from the thyrocervical trunk...

REVIEW
J Bahm
In upper brachial plexus birth injury, rotational balance of the glenohumeral joint is frequently affected and contracture in medial rotation of the arm develops, due to a severe palsy or insufficient recovery of the lateral rotators. Some of these children present with a severe glenohumeral joint contracture in the first months, although regular physiotherapy has been provided, a condition associated with a posteriorly subdislocated or dislocated humeral head. These conditions should be screened early by a pediatrician or specialized physiotherapist...

Multifactorial motion analysis was first established for gait and then developed in the upper extremity. Recordings of infrared light reflecting sensitive passive markers in space, combined with surface eletromyographic recordings and/or transmitted forces, allow eclectic study of muscular coordination in the upper limb. Brachial plexus birth injury is responsible for various patterns of muscle weakness, imbalance, and/or simultaneous activation, soft tissue contractures, and bone-joint deformities, leading to individual motion patterns and adaptations, which we studied by means of motion analysis tools...

This report describes a patient who had an open repair of a small supraspinatus tendon tear performed 6 months after an arthroscopic acromioplasty with debridement had failed to provide pain relief. Three months prior to the tendon repair, he had a two-level cervical spine discectomy and fusion (C4-5, C5-6) that improved his neck pain. Florid suprascapular neuropathy was detected 10 weeks after the open rotator cuff repair. Evidence of some nerve recovery resulted in a long period of observation. But unsatisfactory improvement warranted decompression of the suprascapular notch, which was found to be very stenotic...

A 20-year-old man suffered the combined axillary and suprascapular nerve palsies associated with scapulothoracic dissociation by motorcycle accident. The dislocated shoulder girdle was reduced and stabilized with osteosynthesis of the fractured clavicle and reattachment of the trapezius avulsed from the scapular spine for removal of continuous traction force to these damaged nerves. Because of no evidence of recovery on manual muscle test and electromyogram, exploration for these nerves was administered 6 weeks after injury...

BACKGROUND:  In neurological diseases, winging of the scapula occurs because of serratus anterior muscle dysfunction due to long thoracic nerve palsy, or trapezius muscle dysfunction due to accessory nerve palsy. Several sports can cause long thoracic nerve palsy, including archery and tennis. To our knowledge, this is the first report of long thoracic nerve palsy in an aquatic sport. OBJECTIVE:  The present study is a rare case of winging of the scapula that occurred during synchronized swimming practice...

INTRODUCTION:  The Pancoast syndrome (PS) has been termed after Henry Pancoast. Its neurologic core symptoms include pain, radicular sensory and motor syndromes, and Horner syndrome. A PS is often the presenting sign of lung cancer and bears a grim prognosis. METHODS:  This case report describes an atypical onset of a lung tumor causing a PS. Electrophysiological examination was not conclusive. The diagnosis was confirmed by MRI, CT scan, and biopsy. The intervention consisted of preoperative chemo- and radiotherapy and was followed by an extensive surgical approach with histologically confirmed perineural invasion of the brachial plexus...

Idiopathic brachial neuritis is a distinctive condition that occurs most often in healthy individuals. It characteristically starts with an acute unilateral shoulder pain followed by a complex of symptoms, including weakness, paresthesias, and numbness. The cause of this syndrome is unknown and difficult to diagnose in the initial phase but may occur postsurgery, postinfection, posttrauma, or postvaccination. In this case, the patient's inciting event appeared to be a cesarean section. There was no trauma to the shoulder or upper extremity by way of positioning during the procedure...
