AI Article Synopsis
- A 30-year-old man experienced pain and weakness in his arms following a tractional injury, accompanied by significant muscle atrophy and reduced reflexes.
- Diagnostic tests indicated bilateral brachial plexopathy, with cervical imaging revealing an unusual morphology of the cervical vertebrae and a small rib on the left side contributing to the issue.
- The case highlights a rare instance of traumatic brachial plexopathy linked to thoracic outlet syndrome and a specific muscle anomaly, marking it as a novel finding in medical literature.
Article Abstract
Reported here is a 30-year-old man who was seen because of pain and weakness in the upper extremities after a tractional injury. Physical examination revealed significant atrophy in the left deltoid and right intrinsic hand muscles, generalized hypoesthesia, decreased deep tendon reflexes bilaterally, and decreased strength in various muscle groups. Roos (right) and hyperabduction (bilateral) tests were positive. Electrodiagnostic studies were consistent with bilateral brachial plexopathy. Cervical radiographs showed long transverse process of C7 on the right side and a small rudimentary rib articulating with C7 on the left side. Brachial plexus magnetic resonance imaging demonstrated an aberrant muscle and compressive brachial plexus injury on the left side. Surgery via transaxillary approach was performed on the left side. The occurrence of traumatic brachial plexopathy in the presence of underlying thoracic outlet syndrome and subclavius posticus muscle is discussed for the first time in the literature.

Management of Post-Traumatic Pseudomeningocele as Consequence of Root Nerve Avulsion: Case Report and Review of the Literature.

Department of Neuroscience "Rita Levi Montalcini", University of Turin, 10126 Turin, Italy.
Background: Post-traumatic pseudomeningoceles are common findings after a brachial or lumbar plexus trauma, in particular after nerve root avulsion. Unlike meningoceles, pseudomeningoceles are CSF full-filled cysts confined by the paraspinous soft tissue, along the normal nerve course, in communication with the spinal subarachnoid spaces. Normally no more than a radiological finding at MRI, in rare instances they might be symptomatic due to their size or might constitute an obstacle during a reconstructive surgery.

Neurovascular complications associated with clavicular shaft fractures can manifest at presentation, develop gradually over time, or potentially be iatrogenically induced. Conducting a thorough neurovascular examination and, when warranted, pursuing further investigation through modalities such as CT angiogram, MRI, and nerve conduction studies (NCS) are crucial for early diagnosis and pre-operative planning. This comprehensive approach enhances patient outcomes by facilitating timely intervention and addressing any underlying neurovascular issues associated with the fracture.

Traumatic peripheral nerve injuries represent a spectrum of conditions and remain challenging to diagnose and prognosticate. High-resolution ultrasonography and magnetic resonance neurography have emerged as useful diagnostic modalities in the evaluation of traumatic peripheral nerve and brachial plexus injuries. Ultrasonography is noninvasive, is able to rapidly interrogate large areas and multiple nerves, allows for a dynamic assessment of nerves and their surrounding anatomy, and is cost-effective.

Aim: To explore the effectiveness and safety of Osborne's ligament suspension and ulnar nerve anterior transposition (OLSUNAT) in conjunction with transcutaneous electrical nerve stimulation (TENS) for managing cubital tunnel syndrome (CTS).
Methods: A total of 116 individuals diagnosed with CTS who underwent OLSUNAT in our hospital between October 2020 and December 2023 were retrospectively selected. They were divided into a treatment group (62 cases) and a control group (54 cases) based on whether they received subsequent TENS.
Timing of intravenous dexamethasone and analgesia after brachial plexus block: a randomized, double-blind, placebo-controlled trial.

Background: The addition of intravenous dexamethasone can significantly prolong analgesia and reduce opioid-related side effects after brachial plexus blockade, but the most effective administration time is yet unknown. The objective of this study is to determine if the timing of administration of dexamethasone affects the duration of analgesia after supraclavicular brachial plexus block.
Methods: This is a double-blind, placebo-controlled, randomized trial performed at a single-center, tertiary academic health sciences center.
