Lateral Antebrachial Cutaneous Neuropathy: A Review of 15 Cases.

Background: Lateral antebrachial cutaneous nerve is a terminal sensory branch of the musculocutaneous nerve. Lateral antebrachial cutaneous neuropathy (LABCN) is rare and often underdiagnosed. Less than 100 cases have been described in the orthopedic literature.Methods: It’s a single-center retrospective study. A retrospective chart review of patients with LABCN who were seen over 16 years was performed. Demographics and detailed clinical information were recorded. In addition, electrodiagnostic data were reviewed, and clinical outcome was recorded.Results: Fifteen patients were included in this study. Postsurgical etiology was the most common (n = 7) cause of LABCN. Other cases included antecubital fossa phlebotomy and intravenous placement (n = 4), trauma (n = 1), overuse or repetitive forearm use (n = 2), and dog bite (n = 1). No etiology was found in one case, but the patient had diabetes.Conclusion: Our study proposes that patient positioning during orthopedic surgeries leading to stretch or compression of the lateral antebrachial cutaneous nerve is the most likely cause of LABCN. Antecubital fossa needle placement is the second most common cause of LABCN. However, it’s a rare mononeuropathy and can be underdiagnosed. Therefore, detailed history, examination, and nerve conduction studies of the bilateral lateral antebrachial cutaneous nerve could help establish the diagnosis after other etiologies have been carefully excluded.

Musculocutaneous neuropathy.

Isolated musculocutaneous neuropathy is uncommon. In this study we aimed to determine its causes and clinical presentation and interpret the electrodiagnostic findings associated with this condition. Our investigation was a retrospective review of patients diagnosed with musculocutaneous neuropathy at the Mayo Clinic (Rochester, Minnesota) electromyography (EMG) laboratory between 1997 and 2015. Thirty-two patients with musculocutaneous neuropathy and 5 patients with lateral antebrachial cutaneous neuropathy were identified. The most common cause was acute trauma or surgery (65%). Fourteen percent of the cases were idiopathic and 14% were inflammatory. Pain and sensory disturbance were more common presentations than weakness. Weakness from nerve injury was not noted in 2 patients, suggesting that other muscles may provide adequate elbow flexion/supination. The bilateral absence of lateral antebrachial cutaneous nerve sensory responses suggests an inflammatory cause. Musculocutaneous neuropathy usually results from trauma or iatrogenic injury. Nerve conduction studies alone are insufficient to confirm neuropathy, and needle EMG examination should be a routine part of the diagnostic evaluation. Muscle Nerve 58: 726-729, 2018.

Lateral antebrachial cutaneous neuropathy

Compression neuropathy of the lateral antebrachial cutaneous nerve presents as purely sensory lesions, manifesting as elbow pain or dysesthetic pain over the lateral forearm. It is an infrequent /INS;clinical entrapment syndrome. In this report, we present a case of lateral antebrachial cutaneous nerve/INS; injury which occurs/INS; after splint use/INS;.

Lateral Antebrachial Cutaneous Neuropathy Following the Long Head of the Biceps Rupture

Lateral antebrachial cutaneous neuropathies present as purely sensory lesions, manifesting as elbow pain or dysesthetic pain over the lateral forearm. Classically, entrapment of the lateral antebrachial cutaneous nerve has been documented at the lateral edge of the biceps tendon as it exits the deep fascia in the antecubital fossa. We report a case of lateral antebrachial cutaneous nerve traction neuritis, rather than entrapment, resulting from a rupture of the long head of the biceps. The biceps displaced the nerve laterally, resulting in sensory loss and severe allodynia. The patient's symptoms were relieved with proximal biceps tenodesis.

Purpose: We want to report on one patient who presented with lateral forearm pain caused by compression neuropathy of the lateral antebrachial cutaneous nerve. Materials and Methods: A female patient was managed by operative treatment (biceps tenoplasty) after failure with conservative treatment for 6 weeks. One year later, we evaluated the clinical symptoms and biceps tendon problems such as supination weakness or rupture after the tenoplasty. Results: Her symptom completely subsided immediately at the first postoperative day and her recovery was uneventful. Supination weakness and rupture of the distal biceps tendon were not found after the operation. Conclusion: We have reported here on a case of successful management of lateral antebrachial cutaneous neuropathy by performing biceps tenoplasty, along with a review of the previously published articles.

Lateral Antebrachial Cutaneous Neuropathy as a Result of Positioning While Under General Anesthesia

As the second most common cause for professional liability in anesthetic practice, nerve injuries are a well-recognized complication. We present a case of lateral antebrachial cutaneous neuropathy after prolonged general anesthesia for left medial meniscal transplant and microfracture surgery. In the orthopedic and sports medicine literature, <100 cases have been described. We discuss the possible causes and propose surgical positioning as the most likely cause of postoperative lateral antebrachial cutaneous neuropathy in our patient.

Rucksack-Induced Plexopathy Mimicking a Lateral Antebrachial Cutaneous Neuropathy

A 20-yr-old active duty soldier complained of right lateral forearm numbness that began shortly after carrying 100 lbs of equipment (20-lb load-bearing equipment, 20-lb individual body armor, and 60-lb rucksack) while deployed during Operation Iraqi Freedom. Physical examination revealed normal strength but decreased sensation over the right lateral forearm, thumb, and index finger. Imaging studies were normal. Electrodiagnostic studies revealed an absent right lateral antebrachial cutaneous nerve conduction study with abnormal electromyography findings in the right deltoid and biceps brachii. He was diagnosed with an upper trunk brachial plexopathy. The patient's symptoms gradually resolved with conservative treatment. Although rucksack palsies have been previously reported, this relatively rare cause of brachial plexus injury has been generally declining with the reengineering of more ergonomically favorable rucksacks. It is possible that the additional body armor may have contributed.

Lateral antebrachial cutaneous neuropathy

Lateral antebrachial cutaneous neuropathy is an uncommon, but easily overlooked, cause of elbow pain in the throwing athlete. Compression of the lateral antebrachial cutaneous nerve by the biceps tendon occurs at the nerve's exit point from the brachial fascia just proximal to the elbow flexion crease. Symptoms include pain in the anterolateral elbow and burning dysesthesias radiating into the lateral forearm, particularly when the forearm is fully pronated with the elbow extended. Patients are initially treated conservatively with nonsteroidal antiinflammatory agents, rest, activity modification, and extension block splinting. For those patients who do not respond to nonoperative treatment, surgical decompression of the nerve under local anesthesia provides complete relief of symptoms and return to full activity.
