Ganglion of the anterolateral elbow is rare and may be associated with compression neuropathy of the radial nerve or its branches. Open ganglionectomy implies extensive soft tissue dissection. We present a case of anterolateral elbow ganglion without any compression neuropathy. This was successfully treated with endoscopic ganglionectomy.

Wrist drop is a disorder caused by radial nerve palsy. Because of the radial nerve's innervation of the extensor muscles of the wrist and digits, those whose radial nerve function has been compromised cannot actively extend them. As such, the hand hangs flaccidly in a position of flexion when the patient attempts to bring the arm to a horizontal position. Causes of wrist drop can range for penetrative trauma to external compression (Saturday night palsy) to systemic nutritional deficiencies. Treatment can range from none to surgery, depending on the nature and extent of the injury to the radial nerve.

The radial nerve has a long and tortuous course in the upper limb. Injury to the nerve can occur due to a multitude of causes at many potential sites along its course. The most common site of involvement is in the proximal forearm affecting the posterior interosseous branch while the main branch of the radial nerve is injured in fractures of the humeral shaft. Signs and symptoms of radial neuropathy depend upon the site of injury. Injury to the nerve distal to innervation of triceps brachii results in loss of extensor function with sparing of function of the triceps resulting in the characteristic 'wrist drop'. Injury in the mid-arm is associated with loss of sensation in the dorsolateral aspect of the hand, the dorsal aspect of the radial three-and-a-half digits and in the first web space. Involvement of only the posterior interosseous nerve (PIN) results in weakness of the wrist and digit extensors. Diagnosis relies on clinical examination, electrodiagnostic studies and imaging findings. Plain radiographs are used to identify fracture sites, callus or tumours as cause of compression. Technological advances in ultrasonography have allowed direct visualisation of the involved nerve with assessment of the exact site, extent and type of injury. It yields unmatched information about anatomical details of the nerve. MR imaging adds to soft-tissue details and helps in characterising the lesion. This pictorial review aims to illustrate a wide spectrum of causes of radial neuropathy and emphasises the importance of imaging modalities in diagnosis of neuropathies. TEACHING POINTS: • Radial nerve injuries are assessed by clinical examination and diagnosed using electrodiagnostic and imaging studies. • Knowledge of anatomical relations and course of the nerve is necessary to identify the nerve at pre-determined anatomical locations. • Altered echogenicity and signal intensity, discontinuity of the nerve, focal thickening and cause of compression can be assessed by imaging modalities. • MR imaging helps in confirmation of the ultrasound findings, differentiating similar appearing lesions and provides additional soft-tissue details.
- Acute visual loss and optic disc edema followed by optic atrophy in two cases with deeply buried optic disc drusen: a mimicker of atypical optic neuritis. [Case Reports]
- BOBMC Ophthalmol 2018 Oct 26; 18(1):278
- CONCLUSIONS: Deeply buried ODD may be associated with NAION causing irreversible visual loss and optic disc pallor, a condition easily mistaken for atypical ON. Awareness of such occurrence is important to avoid unnecessary testing and minimize the risk of mismanagement.
- Diagnostic Accuracy of Sensory Clinical Findings of the Hand Dorsum and of Neurography of the Dorsal Ulnar Cutaneous Nerve in Ulnar Neuropathy at the Elbow. [Journal Article]
- APArch Phys Med Rehabil 2018 Oct 21
- CONCLUSIONS: The utility of DUCN neurography and sensory findings of the medial aspect of the dorsum of the hand is limited in the diagnosis of UNE. However, if DUCN SNAP is absent or low in amplitude, it is advisable to check the presence of the anatomical variant of the innervation of the medial aspect of the hand dorsum from SRN.
- Upper Limb Onset of Hereditary Transthyretin Amyloidosis is common in Non-Endemic Areas. [Journal Article]
- EJEur J Neurol 2018 Oct 23
- CONCLUSIONS: Upper limb onset of hereditary ATTR neuropathy is not rare in non-endemic areas. It is important to propose early TTR sequencing of patients with idiopathic upper limb neuropathies, as specific management and treatment are required. This article is protected by copyright.

Our objective was to define the positions of the nerves around the brachial artery and, secondarily, to assess the risk of intraneural injection during dual guided axillary block. Sixty ultrasound-guided axillary blocks were performed. The locations of the musculocutaneous, median, ulnar, and radial nerves relative to the brachial artery were determined. The position of the ulnar nerve was defined in relation to that of the brachial vein, and the position of the musculocutaneous nerve in relation to the coracobrachialis muscle. The locations were confirmed by neurostimulation and injection of local anesthetic was avoided when the current intensities were below 0.3 mA. The incidences of intraneural injection and postblock neurological injury were recorded. The median nerve was located in the upper external quadrant in 89% of cases and the ulnar nerve in the upper internal quadrant (95%), superficial (19%), or deep (81%) to the brachial vein. The radial nerve was located in the lower internal quadrant in 97% of cases, and the musculocutaneous nerve in the lower external quadrant in 85%. Its disposition differed depending on its proximity to the artery (106 ± 26°) or whether it was inside the coracobrachialis muscle (119 ± 15°; P = 0.023). Three intraneural injections were observed (0.5%, one in the median and two in the radial nerves) and no patient had postblock neuropathy. Our study evidences slight anatomical variability among the neural structures in the axillary region and confirms the safety of the axillary technique with double monitoring, using ultrasound to monitor the approach of the needle to the nerve and nerve stimulation at currents > 0.3 mA to reduce the incidence of intraneural injection.

- Thalidomide and neurotrophism. [Review]
- SRSkeletal Radiol 2018 Oct 19
- CONCLUSIONS: The basic lesion was an abnormal quantity rather than quality of mesenchyme. Cell populations result from cellular proliferation, controlled in early limb bud formation by neurotrophism. Thalidomide is a known sensory neurotoxin in adults. In the embryo, sensorineural injury alters neurotrophism, causing increased or diminished cell proliferation in undifferentiated mesenchyme. Differentiation into normal cartilage occurs later, but within an altered mesenchymal mass. Reduction or excess deformity results, with normal histology, a significant finding. The primary pathological condition is not in the skeleton, but in the nerves.
