“…In addition, the MRN examination helps to identify the exact location of the neuropathy before surgery is required, so that surgery can be performed with less time, smaller incision areas and more precise treatment[ 19 ]. Certainly, high frequency ultrasonography is a reliable, convenient and non-invasive diagnostic imaging method for accurately locating the hourglass-like constriction neuropathy and extent of neuropathy in the anterior interosseous nerve[ 20 ].…”

BACKGROUND Hourglass-like constriction neuropathy is a rare neurological disorder. The main clinical manifestation is peripheral nerve injury with no apparent cause, and the pathomorphological change is an unexplained narrowing of the diseased nerve. The diagnosis and treatment of the disease are challenging and there is no accepted diagnostic or therapeutic approach. CASE SUMMARY This report describes a rare hourglass constriction of the anterior interosseous nerve in the left forearm in a 47-year-old healthy male who was treated surgically and gradually recovered function over a 6-mo follow-up period. CONCLUSION Hourglass-like constriction neuropathy is a rare disorder. With the development of medical technology, more examinations are now available for diagnosis. This case aims to highlight the rare manifestations of Hourglass-like constriction neuropathy and provides a reference for enriching the clinical diagnosis and treatment experience.

“…Однако у пациентов с синдромом ПМН, получивших хирургическое лечение, показано наличие изменений выше предполагаемого клинически уровня поражения срединного нерва -на плече, а не на уровне отхождения ПМН на предплечье, что согласуется с данными литературы [23,34]. вывОДы Пациенты с синдромом ПМН требуют тщательного сонографического обследования для подтверждения локализации поражения срединного нерва, что позволит выбирать верный уровень для нейрохирургического вмешательства.…”

Background. The anterior interosseus nerve (AIN) syndrome is a rare pathology, with cause is discussed. The findings in isolated AIN patients are in the main trunk of median nerve. It is confirmed by neuroimaging data and intraoperative picture in the form of the construction of fascicles in the nerve.Aim. To describe the clinical and instrumental characteristics of patients with isolated non-traumatic lesion of AIN.Materials and methods. The clinical, electrophysiological and neuroimaging data of 7 patients with isolated nontraumatic lesion of AIN were retrospectively analyzed, three of whom underwent surgical treatment.Results. All patients complained of neuropathic pain in the affected upper limb, with an average intensity of 8 points according to visual analog scale and a duration of 1.5 to 4 weeks. Weakness of the flexor pollicis longus from 1 to 3 points on the MRC (Medical Research Council Weakness) scale was observed in all cases, weakness of flexion of the distal phalanx of the index finger in 6 patients from 1 to 3 points, which indicated an isolated lesion of the anterior interosseous nerve.Needle electromyogram revealed denervation in c in all cases, 5 patients – in the pronator teres.The fascicular constriction from 1 or 2 sections of the median nerve were detected at the shoulder level on the affected side by ultrasound in 6 patients. An increase in the cross-sectional area of the median nerve at the shoulder level in 2 cases we observed, in one case the changes were o bilateral and asymmetric. In 2 cases, an increase in cross-sectional area of С5 root was noted on the affected side by no more than 23 % of the normal value. A change in echogenicity and size decrease of the pronator quadratus, when compared with the opposite side, was noted in all cases.Conclusion. Patients with isolated AIN syndrome needs intensive evaluation to identify the localization of the level of damage to the median nerve.
