INTRODUCTION: Ulnar neuropathy at the elbow (UNE) is a common peripheral compression neuropathy and in most cases occurs at 2 sites, the retroepicondylar groove or the cubital tunnel. With regard to a potential therapeutic approach with perineural corticosteroid injection the aim of this study was to evaluate the distribution of injection fluid applied at a standard site. METHODS: We performed ultrasound-guided (US-guided) perineural injections to the ulnar nerve halfway between the olecranon and the medial epicondyle in 21 upper limbs from 11 non-embalmed cadavers...

Neurogenic thoracic outlet syndrome (TOS) is one of the most controversial pain syndromes of the upper limbs. The controversies revolve around both the diagnosis and treatment of the non-specific or subjective subtypes. Their diagnosis rests on a combination of history, suggestive symptoms and clinical examination. Proximal pain is primarily muscular in origin, while distal symptoms may be the result of intermittent nerve compression and/or myofascial pain syndrome. Stringent clinical criteria are required to confirm the diagnosis of subjective TOS...

Neuropathy is a common complication of diabetes mellitus (DM) with a wide clinical spectrum that encompasses generalized to focal and multifocal forms. Entrapment neuropathies (EN), which are focal forms, are so frequent at any stage of the diabetic disease, that they may be considered a neurophysiological hallmark of peripheral nerve involvement in DM. Indeed, EN may be the earliest neurophysiological abnormalities in DM, particularly in the upper limbs, even in the absence of a generalized polyneuropathy, or it may be superimposed on a generalized diabetic neuropathy...

INTRODUCTION: Carpal Tunnel Syndrome (CTS) is the most common nerve entrapment. Subjective sensory symptoms are common place in patients with CTS, but sometimes they are not supported by objective findings in the neurological examination. Electrodiagnostic (EDx) studies are a valid and reliable means of confirming the diagnosis. The amplitudes along with the conduction velocities of the sensory nerve action potential and motor nerve action potential reflect the functional state of axons, and are useful parameters and complement the clinical grading in the assessment of severity of CTS...

While investigating the cause of entrapment syndrome of the peripheral nerves in the elbow region, we observed variability of the pronator teres muscle and the relationship of this muscle to the median nerve and the surrounding vessels. Attention was also paid to the occurrence of the supracondylar process of the humerus and Struthers' ligament with regard to their ontogenetic and phylogenetic development. For this purpose, a classical anatomical dissection of the upper limbs of 68 adults, three fetuses and a phylogenetic assessment of five mammalian species was performed...

BACKGROUND: Musculoskeletal disorders are one of the most common work-related diseases. Frequently this association is thought to have a temporal cause-effect relation. The absence of accessible diagnostic criteria and ethological cause-effect demonstration are probably important reasons for the lack of good evidence data on these pathologies. OBJECTIVE: For these reasons, the authors aim to present a systematic review on prevalence and incidence of the upper limb WRMSD...

INTRODUCTION: Carpal tunnel syndrome (CTS) is one of the most common entrapment neuropathies of the upper limbs. It results from compromised median nerve function of the wrist that is caused by increased pressure in the carpal tunnel. Repetitive use of the hand and wrist, obesity, pregnancy, rheumatoid diseases, trauma and endocrinopathies are some of the risk factors for CTS. AIM: The purpose of this study was to find out whether patients with diabetes mellitus (DM), hypothyroidism and acromegaly have an increased incidence of carpal tunnel syndrome compared to each other and normal population...

The biceps brachii is one of three muscles of the anterior compartment of arm. Variations of the biceps brachii are not rare. The most frequent is the existence of a third head called the humeral head by Le Double (1897) (Rodríguez-Vázquez et al., 1999). Our article is based on the unexpected result of a routine dissection class held for medical students. Dissection was performed according to the guidelines accepted by the anatomy department (Seichert, 1999). We describe a third (accessory) head of the biceps brachii...

STUDY DESIGN: A cross-sectional cadaveric examination of displacement and strain measured at the level of the cervical nerve roots during upper limb neural tension testing (ULNTT) with median nerve bias. OBJECTIVE: To determine the displacement and strain of cervical nerve roots C5-C8 during ULNTT with minimal disruption of surrounding tissues. SUMMARY OF BACKGROUND DATA: Clinical examination of neural pathology involving cervical nerve roots is difficult because of the transient nature of pathologies, such as cervical radiculopathy, entrapment neuropathies, and thoracic outlet syndrome...

Herpes zoster is a secondary reactivation of primary contagious varicella-zoster virus in the dorsal root ganglia. While thoracic zona is common, cervical dermatomal zona is a rare segmental complication of herpes zoster and can be easily misdiagnosed as other diseases. This article describes a patient with initial neuralgia without dermatomal lesions that was treated as ulnar nerve entrapment syndrome until manifestation of herpetiform cutaneous lesions appeared. It is important that clinicians should be aware of the possibility of zoster infection when evaluating the onset of neuralgia in a dermatomal distribution in the upper limb, especially without rash...

OBJECTIVES: Variations such as communications between median nerve and musculocutaneous nerve or in their abnormal branching pattern constitute a major concern in clinical and surgical field. Knowledge of these variations not only provides the clinician with a proper interpretation of the case, but also minimizes the complication in surgical approaches in this region. METHOD: We examined 50 isolated upper limbs to investigate the possible incidences of various types of communications between these two neighbouring peripheral nerves...

Several open and endoscopic techniques for the surgical treatment of ulnar nerve entrapment at the elbow (cubital tunnel syndrome) have been described that provide decompression with or without anterior transposition. Based on our experience with US-guided decompression for carpal tunnel syndrome in our department, we developed a similar surgical technique for the decompression of the ulnar nerve at the elbow. Using sixteen cadaver upper limbs, we performed decompression of all the structures possibly responsible for ulnar nerve compression at the elbow...

Cubital tunnel syndrome is one of the common upper extremity problem encountered. A mild syndrome can be often treated without surgery, but a failure of conservative treatment with constant symptoms or muscle atrophy and weakness requires surgical intervention. Despite the fact that is the second most common nerve entrapment in the upper limb, there is no accepted gold standard in the surgical management. But with the new technique in minimally invasive surgery and available endoscope, it addresses all potential compression sites with good visualisation but with small surgical exposure...

The direct causes of idiopathic carpal tunnel syndrome (CTS), a common upper limb entrapment neuropathy, remain unknown. It is however generally accepted that an increase in pressure within the carpal tunnel structure, which contains nine flexor tendons, causes compression of the median nerve. The involvement of these tendons in the aetiology of CTS cannot be excluded. Variants within the collagen, type V, alpha 1 (COL5A1) gene, which encodes for the α1 chain of type V collagen, an important regulator of fibril assembly in tendons, have previously been associated with Achilles tendinopathy...
