“…In 2010, the American investigators drew attention to the phenomenon of physiological change of shape of the nerve at the entry to the supinator muscle ( 52 ) . They described 50 elbows in 47 asymptomatic patients and found that despite nerve flattening at its entry to the supinator muscle, its cross-sectional area does not change in a significant way.…”

The primary aim of this paper was to assess the relevance of high-frequency ultra-sound examination in qualifying patients for either surgical or conservative treatment of peripheral entrapment neuropathies. The study was conducted in a group of 55 patients aged 7–83 (mean age 43.6), including 28 males and 27 females, who in 2009–2011 were referred to an ultrasound examination due to a clinical suspicion of entrapment neuropathies. For the purposes of the analysis, the patients were divided into four groups: carpal tunnel syndrome (1), ulnar nerve entrapment (2) (cubital tunnel syndrome and Guyon's canal syndrome), posterior interosseous nerve syndrome (3) and other entrapment neuropathies (4). The cases of isolated idiopathic carpal tunnel syndrome were excluded from the analysis. All patients underwent the interview, physical examination and ultrasound examination. Ultrasound examinations were performed with Esaote MyLab 50 and MyLab 60 systems using high-frequency broadband linear transducers: 6–18 MHz. Sixty-seven percent of patients (37 persons) underwent a neurophysiological test. Nerve echostructure, its hyperemia as well as nerve cross-sectional area or, in the case of small nerves, diameter were assessed in all patients. Furthermore, the following were assessed in individual groups: notch sign in group 1, nerve instability in a dynamic ultrasound examination in group 2, nerve angulation in a dynamic ultrasound examination and tenderness on nerve compression at the site of the visualized pathology in group 3. The analyses of the collected material were performed by means of descriptive statistics. The results of clinical and surgical verification were consistent with ultrasound findings in 96.4%. The results indicate that high-frequency ultrasonography is a valuable method in qualifying patients for various types of treatment of peripheral neuropathies resulting from compression.

“…8,[33][34][35] Fourteen studies reported multiple means at a given anatomical site, such as separate means for males and females, or for right and left sides. 20,[34][35][36][37][38][39][40][41][42][43][44][45][46] The greatest variability in nerve CSA was seen in the brachial plexus, tibial-popliteal fossa, and all three sciatic nerve small groups. When combining all anatomical locations for individual nerve measurements, the tibial nerve (n = 2916 nerves) was the most assessed, followed by the common fibular nerve (n = 2580 nerves), radial nerve (n = 2326 nerves), sciatic nerve (n = 1470 nerves), sural nerve (n = 1316 nerves), and brachial plexus (n = 1314 nerves).…”

Sonographic peripheral nerve cross‐sectional area in adults, excluding median and ulnar nerves: A systematic review and meta‐analysis

Introduction/Aims Although electromyography remains the “gold standard” for assessing and diagnosing peripheral nerve disorders, ultrasound has emerged as a useful adjunct, providing valuable anatomic information. The objective of this study was to conduct a systematic review and meta‐analysis evaluating the normative sonographic values for adult peripheral nerve cross‐sectional area (CSA). Methods Medline and Cochrane Library databases were systematically searched for healthy adult peripheral nerve CSA, excluding the median and ulnar nerves. Data were meta‐analyzed, using a random‐effects model, to calculate the mean nerve CSA and its 95% confidence interval (CI) for each nerve at a specific anatomical location (= group). Results Thirty groups were identified and meta‐analyzed, which comprised 16 from the upper extremity and 15 from the lower extremity. The tibial nerve (n = 2916 nerves) was reported most commonly, followed by the common fibular nerve (n = 2580 nerves) and the radial nerve (n = 2326 nerves). Means and 95% confidence interval (CIs) of nerve CSA for the largest number of combined nerves were: radial nerve assessed at the spiral groove (n = 1810; mean, 5.14 mm2; 95% CI, 4.33 to 5.96); common fibular nerve assessed at the fibular head (n = 1460; mean, 10.18 mm2; 95% CI, 8.91 to 11.45); and common fibular nerve assessed at the popliteal fossa (n = 1120; mean, 12.90 mm2; 95% CI, 9.12 to 16.68). Publication bias was suspected, but its influence on the results was minimal. Discussion Two hundred thirty mean CSAs from 15 857 adult nerves are included in the meta‐analysis. These are further categorized into 30 groups, based on anatomical location, providing a comprehensive reference for the clinician and researcher investigating adult peripheral nerve anatomy.

“…However, ultrasound is being used more frequently in various clinical settings to evaluate the injury and recovery phases of nerve, thus influencing the diagnosis and clinical care of symptomatic patients[13535455]. The sudden onset and severity of the earthquake led to peripheral nerve injuries in many unique cases, which allowed us to evaluate the natural history of these injuries and the impact of surgical treatments in the recovery of these nerves.…”

Published data on earthquake-associated peripheral nerve injury is very limited. Ultrasonography has been proven to be efficient in the clinic to diagnose peripheral nerve injury. The aim of this study was to assess the role of ultrasound in the evaluation of persistent peripheral nerve injuries 1 year after the Wenchuan earthquake. Thirty-four patients with persistent clinical symptoms and neurologic signs of impaired nerve function were evaluated with sonography prior to surgical repair. Among 34 patients, ultrasonography showed that 48 peripheral nerves were entrapped, and 11 peripheral nerves were disrupted. There was one case of misdiagnosis on ultrasonography. The concordance rate of ultrasonographic findings with those of surgical findings was 98%. A total of 48 involved nerves underwent neurolysis and the symptoms resolved. Only five nerves had scar tissue entrapment. Preoperative and postoperative clinical and ultrasonographic results were concordant, which verified that ultrasonography is useful for preoperative diagnosis and postoperative evaluation of injured peripheral nerves.
