“…Martin-Gruber anastomosis is a commonly found connection between the median and ulnar nerves in the forearm, as described in the literature (10,6). However, it is quite rare for a connection to exist from the ulnar to the median nerve, and it usually indicates abnormalities (Marinacci anastomosis) (11).…”

Objectives:The purpose of this systematic review is to examine the different variations of the median nerve (MN) and the diagnostic methods used to identify carpal tunnel syndrome (CTS), a common neuropathy resulting from the entrapment of the MN within the carpal tunnel. Understanding the different variations of the MN is crucial in order to prevent injuries during surgical treatment of the syndrome.Material and methods: Data were extracted from studies published in PubMed. A detailed search in PubMed was performed for studies that reviewed the variations of the MN and CTS.Results: There are two main classifications of the MN, known as the Lanz and Amadio categories. Lanz's classification is the one being mostly used in the surgical literature, with group 3 (Bifid MN) being the main cause of the CTS. Additionally, there are branches and anastomosis of the MN that do not fit into either category, with the third common digital branch being the most injured nerve during carpal tunnel release surgery. Diagnostic techniques for CTS include physical examination combined with NCS tests, magnetic resonance imaging (MRI), ultrasound, or elastography. While NCS has been previously the most commonly used diagnostic method, the recent literature suggests that ultrasound and elastography are the most accurate techniques.Conclusions: In order to minimize injuries during carpal tunnel release surgery, it is crucial to have knowledge on the different variations of the MN that cause CTS. Additionally, this review emphasizes the significance of the current diagnostic methods, which not only make CTS more affordable but also facilitate easier recognition of the condition.

“…In a study by Sur et al, 25 the Martin-Gruber anastomosis (MGA) occurred with a prevalence of 15.7%. The MGA emerges as a communicating branch in the cubital fossa from the main trunk of the MN, crossing superficially to the flexor digitorum superficialis or flexor digitorum profundus muscles before joining the UN.…”

Profound knowledge of nerve variations is essential for clinical practice. It is crucial for interpreting the large variability of a patient's clinical presentation and the different mechanisms of nerve injury. Awareness of nerve variations facilitates surgical safety and efficacy. Clinically significant anatomical variations can be classified into two main groups: variability in the course of the nerve and variability of structures surrounding the nerve. In this review article we focus on the most common nerve variants of the upper extremity and their clinical relevance.

Nerve entrapment syndromes are commonly encountered in clinical practice. Accurate diagnosis and management require knowledge of peripheral neuroanatomy and recognition of key clinical symptoms and findings.Nerve entrapment syndromes are frequently associated with structural abnormalities of the affected nerve. Therefore, imaging allows for the evaluation of the cause, severity, and etiology of the entrapment. High resolution ultrasonography can depict early and chronic morphological changes within the entire nerve course and is therefore an ideal modality for the diagnosis of various nerve entrapment syndromes at different regions. This review article presents some of the most common nerve entrapments, with special focus on ultrasound imaging and key findings.
