An anatomical investigation of rare upper limb neuropathies due to the Struthers' ligament or arcade: a meta-analysis.

Folia Morphol (Warsz) 2020 May 12. Epub 2020 May 12.

Department of Anatomy, Jagiellonian University Medical College, Krakow, Poland.

The Struthers' ligament is a fibrous band that originates from the supracondylar humeral process and inserts into the medial humeral epicondyle, potentially compressing both the median nerve and brachial artery. The controversial Struthers' arcade is a musculotendinous band found in the distal end of the arm that might compress the ulnar nerve. This study aimed to evaluate the pooled prevalence estimate of the Struthers' ligament and arcade, and their anatomical features. Read More

Ulnar nerve subluxation and dislocation: a review of the literature.

Neurosurg Rev 2020 Apr 27. Epub 2020 Apr 27.

Department of Neurosurgery, Tulane Center for Clinical Neurosciences, Tulane University School of Medicine, 131 S. Robertson St. Suite 1300, New Orleans, LA, 70112, USA.

The pathogenesis of ulnar nerve subluxation and dislocation is widely debated. Upon elbow flexion, the ulnar nerve slips out of the groove for the ulnar nerve, relocates medial or anterior to the medial epicondyle, and returns to its correct anatomical position upon extension. This chronic condition can cause neuritis or neuropathy; however, it has also been suggested that it protects against neuropathy by reducing tension along the nerve. Read More

Ultrasound elastography as a potential method to evaluate entrapment neuropathies in elite athletes: a mini-review.

Pol J Radiol 2019 28;84:e625-e629. Epub 2019 Dec 28.

Gruca Orthopaedic and Trauma Teaching Hospital, Centre of Postgraduate Medical Education, Otwock, Poland.

Entrapment neuropathies constitute a significant albeit still neglected problem in athletes. Currently available diagnostic options in patients with suspected neuropathies, nerve conduction studies, and magnetic resonance imaging have some drawbacks, mostly related to their invasive character, high cost, and limited availability. This paper reviews published articles documenting the use of ultrasound elastography, a novel technique to determine tissue strain, in the evaluation of nerve stiffness in entrapment neuropathy, and it discusses potential pros and cons of this method in the examination of elite athletes.

Short-term cane use in subacute stroke patients affects the nonparetic upper extremity nerves.

Int J Rehabil Res 2020 Jun;43(2):148-153

Department of Rehabilitation Medicine, Eulji University Hospital, Eulji University School of Medicine, Daejeon, Republic of Korea.

Overuse of the nonparetic upper extremity can lead to entrapment neuropathies in chronic stroke patients. However, little is known about the effects of cane use in subacute stage of stroke. The aim of this study was to investigate the short-term effects of cane use on the upper extremity nerves in subacute stroke patients recovering from a bedridden state. Read More

Reconstruction of lateral pinch in an isolated paralysis of the first dorsal interosseous muscle - A new surgical technique.

Orthop Traumatol Surg Res 2020 Apr 7;106(2):353-356. Epub 2020 Feb 7.

Department of orthopedics and hand surgery, Saint-Antoine hospital, Paris, France.

Lack of function of the first interosseous muscle (FDI) might be responsible for insufficient stabilisation of the index finger during lateral pinch, and may induce disability in hand function. The first cause of FDI palsy is ulnar nerve palsy. We describe a new tendon transfer to reanimate the FDI muscle, using the extensor indicis proprius tendon. Read More

Validity of computed tomographic measurements and morphological comparison of cubital tunnel in idiopathic cubital tunnel syndrome.

BMC Musculoskelet Disord 2020 Feb 5;21(1):76. Epub 2020 Feb 5.

Department of Orthopedic Surgery, Eulji University College of Medicine, 1306 Dunsan-dong, Seo-gu, Daejeon, 302-799, South Korea.

Background: Ulnar neuropathy is a common reason for referral to hand surgeons, and 10 to 30% of cubital tunnel syndrome (CuTS) is idiopathic. We hypothesized that the cause of idiopathic CuTS is in the bony structure.

Methods: We analyzed 79 elbows (39 idiopathic CuTS and 40 without CuTS symptom) using computed tomography and Materialize Mimics software to compare the differences between the two groups. Read More

Neuromuscular Mimics of Entrapment Neuropathies of Upper Extremities.

Hand (N Y) 2020 Feb 5:1558944719898801. Epub 2020 Feb 5.

The University of Iowa Carver College of Medicine, Lowa, USA.

Carpal tunnel syndrome and ulnar neuropathy are such common maladies affecting the upper extremties that they often become the default diagnosis when patients complain of numbness, pain, or weakness of the hands. While often correct, there are a number of other conditions that can also cause sensory or motor loss of the hands, which should be considered when appropriate, as they can mimic upper extremity entrapment syndromes. In this review, we will discuss such mimics, including Charcot-Marie-Tooth disease, multifocal motor neuropathy, hereditary neuropathy with pressure palsies, mononeuropathy multiplex, Lewis-Sumner syndrome, brachial plexitis (Parsonage-Turner syndrome), myotonic dystrophy, inclusion body myopathy, and distal myopathy of Welander.
