BACKGROUND: In combined high median and ulnar nerve injury, transfer of the posterior interosseous nerve branches to the motor branch of the ulnar nerve (MUN) is previously described in order to restore intrinsic hand function. In this operation a segment of sural nerve graft is required to close the gap between the donor and recipient nerves. However the thenar muscles are not innervated by this nerve transfer. The aim of the present study was to evaluate whether the superficial radial nerve (SRN) can be used as an "in situ vascular nerve graft" to connect the donor nerves to the MUN and the motor branch of median nerve (MMN) at the same time in order to address all denervated intrinsic and thenar muscles...

INTRODUCTION: Minimally invasive cardiac surgery (MICS), via minithoracotomy, is thought to be a fast track to extubation and recovery after surgery. Chronic pain, due to intercostal nerve injury, develops in up to 50% of postthoracotomy patients.A number of regional anaesthesia and analgesia techniques may be employed, and the anaesthesiologists play a key role in facilitating optimal outcomes after surgery. METHODS: We report a case of postoperative pain management with a local anesthetic infiltration for MICS...

Aneurysms of the subclavian artery are rare phenomena that have the potential for limb and life-threatening complications. Delayed diagnosis increases the risk of life-threatening complications or at the very least may result in a detrimental effect to both functional capacity and quality of life; primary care offers a vital opportunity to screen for such rare vascular complications and should be a consideration in all patients with evolving peripheral nerve or vascular symptoms with a history of localized clavicular trauma...

Aims: Complex regional pain syndrome (CRPS) is characterized by chronic debilitating pain disproportional to the inciting event and accompanied by motor, sensory, and autonomic disturbances. The pathophysiology of CRPS remains elusive. An exceptional case of severe CRPS leading to forearm amputation provided the opportunity to examine nerve histopathological features of the peripheral nerves. Methods: A 35-year-old female developed CRPS secondary to low voltage electrical injury. The CRPS was refractory to medical therapy and led to functional loss of the forelimb, repeated cutaneous wound infections leading to hospitalization...

Compression of the radial nerve is most commonly described at the supinator muscle (i.e., arcade of Frohse). However, radial nerve compression can occur in the arm. Therefore, the purpose of this article is to review both etiologies of radial nerve entrapment and the sites at which this can occur in the arm. The clinical presentation of radial nerve entrapment in the arm and how it differs from that of entrapment at other sites is reviewed and the conditions potentially predisposing to nerve entrapment are described...

Voluntary elbow extension is essential for optimal upper limb positioning required for daily living activities, particularly above-shoulder maneuvers. The authors present a case of traumatic brachial plexus injury in which paralysis of the musculature selectively supplied by the posterior cord was based on magnetic resonance imaging and nerve conduction studies. An attempt at a radial nerve graft at another center was not effective. Ipsilateral hand function improved after multiple local tendon transfers were performed...

BACKGROUND: Volar locking plate fixation of distal radius fractures is commonly performed because of its good clinical outcomes. The flexor carpi radialis (FCR) approach is one of the most popular approaches to dissecting the volar side of the distal radius because of its simplicity and safety. We describe an extremely rare case of an absent FCR identified during a volar approach for fixation of a distal radius fracture. CASE PRESENTATION: A 59-year-old woman with distal radius fracture underwent surgery using the usual FCR approach and volar locking plate...

REVIEW
Mark S Ayoub, Ivan S Tarkin
For younger patients with extra-articular distal humerus fractures closed management is plagued with high rates of malunion, suboptimal functional outcomes, extended immobilization with loss of early motion, a delay in return to work, and a general period of lost productivity. Surgical management offers an appealing alternative. Maintaining respect for the triceps musculature and minimizing iatrogenic injury to the radial nerve are primary concerns with operative treatment. Accordingly, use of a triceps-sparing approach and single column plating may be the optimal treatment paradigm in the young patient presenting with an extra-articular distal humerus fracture...

BACKGROUND: Neuro-axonal injury is a key contributor to non-reversible long-term disability in multiple sclerosis (MS). However, the underlying mechanisms are not yet fully understood. Visual impairment is common among MS patients, in which episodes of optic neuritis (ON) are often followed by structural retinal damage and sustained functional impairment. Alterations in the optic nerve and retina have also been described in rodent experimental autoimmune encephalomyelitis (EAE), a model of MS...

PURPOSE: The posterior interosseous nerve (PIN) is at risk during the posterior and lateral approaches to the proximal radius. We aimed to define a safe zone for these approaches to avoid injury of the PIN and to evaluate their close and changing relationship to the nerve during forearm rotation. METHODS: The study collective consisted of 50 upper limbs. After performance of the lateral approach, the distance between the tip of the radial head and the PIN's exit point from the supinator (= distance 1) and the shortest interval between the nerve's exit to the radial margin of the ulna (= distance 2) were measured in maximum pronation and supination...

We present a case of an injury to the superficial branch of the radial nerve following unconscious radial artery cannulation in a 57-year-old gentleman for revision of lumbar spinal fusion. Nerve damage is a rare complication of this commonly used technique; whilst usually self-limiting, it can lead to a significant under-reported burden of morbidity on our patients. We discuss current norms of practice, questioning the safety of unconscious arterial cannulation, and suggest that, where possible, it should be performed in the conscious patient to minimise the risk of this rare complication...

We report a case of a 29-year-old man who presented with a distal humeral shaft fracture sustained by blunt trauma. Physical examination and nerve conduction study were consistent with injury to the median and radial nerves proximal to the elbow. The patient underwent open reduction and internal fixation of the humeral shaft fracture with neurolysis of the median and radial nerves. Repeat electromyography at 6 months postoperatively showed recruitment of motor units in all muscles sampled, in keeping with clinical improvement...

Aims Supracondylar fractures are the most frequently occurring paediatric fractures about the elbow and may be associated with a neurovascular injury. The British Orthopaedic Association Standards for Trauma 11 (BOAST 11) guidelines describe best practice for supracondylar fracture management. This study aimed to assess whether emergency departments in the United Kingdom adhere to BOAST 11 standard 1: a documented assessment, performed on presentation, must include the status of the radial pulse, digital capillary refill time, and the individual function of the radial, median (including the anterior interosseous), and ulnar nerves...

BACKGROUND: Children have a curiosity for climbing walls, stairs, and railings and have an increased risk of falling. Here, we report our experience with railings causing injuries by penetrating the upper extremities, and aim to call attention to spiked railing injuries in children. METHODS: We report on five children with a mean age of 8.8. All of the children were male. The penetrating railing parts were removed in a surgical room. RESULTS: The injured structures repaired immediately were as follows: flexor digitorum profundus tendon, A4 pulley, volar plate of the distal interphalangeal joint, radial digital nerve, ulnar digital artery, and radial digital artery...

BACKGROUND: In adults, a relative "safe zone" for lateral approaches to the elbow has been well described in efforts to reduce iatrogenic injury, typically a minimum of 6 cm proximal to the lateral epicondyle. To avoid iatrogenic injury to the radial nerve intraoperatively, we investigated the distance of the nerve from the distal humeral physis in children. METHODS: All patients who had axial and coronal T1-weighted magnetic resonance imagings of the humerus and elbow between 2005 and 2015 were eligible...

BACKGROUND: We analyzed the clinical and electrophysiologic patterns of nerve injury in pediatric patients with radial neuropathy. METHODS: This is a retrospective analysis of 19 children and adolescents with radial neuropathy. RESULTS: The mean subject age was 12 years (range one month to 19 years), 56% were female, and 53% had traumatic etiologies. Weakness in the finger and wrist extensors was the prevailing complaint (82%). Predominant localization was at the posterior interosseous nerve (37%), followed by the radial nerve below the spiral groove (32%), the radial nerve at the spiral groove (26%), and the radial nerve above the spiral groove (5%)...
