“…It has been noted that the UN moves easily within the arcade. In one study, the musculotendinous type was observed in 54.2% cases, purely tendinous in 38.5%, and purely muscular in 7.2% (Mizia et al, 2021). It typically extends from the MIMS to the medial head of triceps brachii with a variable distance from the medial epicondyle of the humerus (Caetano et al, 2017).…”

Possible points of compression of the ulnar nerve: Tricks and traps that await clinicians from an anatomical point of view

et al. 2021

The ulnar nerve can be subject to numerous types of compression. The most common are cubital tunnel and ulnar tunnel syndromes, but there are many others with more uncommon etiologies. The existence of additional communicating branches, median nerve involvement, various types of injuries, and unusual anatomical variations can be a challenge for both diagnosis and treatment. This review presents a comprehensive depiction of ulnar nerve entrapment syndromes with particular reference to their anatomical background, risk factors, and clinical evaluation. Even common disorders can result from atypical morphological changes. It is important to be familiar with them as it is a key ability in daily medical practice.

“…Regardless of its character, it is questionable whether this structure can be a primary cause of the entrapment. However, it is seriously considered as a risk factor of recurrent ulnar neuropathy as a result of the UN transposition (Mizia et al, 2021).…”

“…In a meta-analysis by Mizia et al, the overall estimated pooled prevalence of the ligament was 1.8% and was 52.6% for the arcade. 42 The presence of accessory muscles like the anconeus epitrochlearis muscle, thought to be a muscular execution of Osborne's ligament, is important because it can lead to nerve entrapment. It occurs in > 18% of the European population 43,44 (►Fig.…”

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.

“…Struthers' arcade is a non-constant, morphologically variable tendinous or muscular tissue situated 6-10 cm proximal to the medial epicondyle (ME), between the medial head of the triceps brachii muscle and MIS (1). Mizia et al (8) estimated its prevalence as 53%. Tubbs et al (9) described three types of Struthers' arcade.…”

Ulnar Neuropathy at the Elbow: From Ultrasound Scanning to Treatment

et al. 2021

View full text Add to dashboard Cite

Ulnar neuropathy at the elbow (UNE) is commonly encountered in clinical practice. It results from either static or dynamic compression of the ulnar nerve. While the retroepicondylar groove and its surrounding structures are quite superficial, the use of ultrasound (US) imaging is associated with the following advantages: (1) an excellent spatial resolution allows a detailed morphological assessment of the ulnar nerve and adjacent structures, (2) dynamic imaging represents the gold standard for assessing the ulnar nerve stability in the retroepicondylar groove during flexion/extension, and (3) US guidance bears the capability of increasing the accuracy and safety of injections. This review aims to illustrate the ulnar nerve's detailed anatomy at the elbow using cadaveric images to understand better both static and dynamic imaging of the ulnar nerve around the elbow. Pathologies covering ulnar nerve instability, idiopathic cubital tunnel syndrome, space-occupying lesions (e.g., ganglion, heterotopic ossification, aberrant veins, and anconeus epitrochlearis muscle) are presented. Additionally, the authors also exemplify the scientific evidence from the literature supporting the proposition that US guidance is beneficial in injection therapy of UNE. The non-surgical management description covers activity modifications, splinting, neuromobilization/gliding exercise, and physical agents. In the operative treatment description, an emphasis is put on two commonly used approaches—in situ decompression and anterior transpositions.
