About the Study

The appearance of ulnar nerve entrapment at the wrist differs depending on the differential anatomy and compression site or sites. As a result, knowing the anatomy of the Guyon canal is critical for diagnosing patients who have motor and/or sensory deficiencies in the hand. Soft-tissue tumours, recurrent or acute trauma, the presence of aberrant muscles and fibrous bands, arthritic, synovial, endocrine, and metabolic disorders, and iatrogenic injury are all causes of ulnar nerve compression. Imaging and electro diagnostic investigations, in addition to a complete history and physical examination that includes motor, sensory, and vascular assessments, aid in the identification of ulnar nerve lesions at the wrist. A distal compression lesion produced by repetitive exercise can be treated non-surgically, but if symptoms continue or increase after 2 to 4 months, surgical decompression is required.

The authors give a classification of three unique ulnar-nerve compression syndromes at the wrist and hand, along with typical examples, and reported cases have been categorized according to the region of compression. There is sensory loss in the ulnar distribution as well as some distal loss in Type I (proximal lesion). Only a pure motor or sensory loss exists in Types II and III (distal lesions), respectively. For more accurate localization of the injury site, a preoperative examination plan is proposed. The recommended treatment is surgical decompression of the common reversible ulnar neuropraxia.

Acute ulnar neuropathy of the wrist is a rare illness that sometimes necessitates a strong index of suspicion to diagnose. Because of the nerve's convoluted anatomic path in distal locales, clinical manifestations of ulnar nerve lesions at the wrist and hand vary. A ganglion in Guyons canal induced acute ulnar neuropathy at the wrist, which was initially misdiagnosed as flexor tenosynovitis. Electrophysiological testing was used to confirm the diagnosis of selective distal motor neuropathy of the ulnar nerve. A well-defined soft tissue mass, consistent with a ganglion, was found compressing the ulnar nerve in Guyons canal on magnetic resonance imaging. Entrapment neuropathies are a prevalent condition that physiatrists treat. In the differential diagnosis of individuals with wrist or hand discomfort, ulnar nerve lesions at the wrist should be considered. In the anatomical examination of acute focal neuropathies, magnetic resonance imaging is a valuable tool.

An instance of ulnar nerve compression at the wrist is described in Guyons canal. The clinical picture looked to be that of an ulnar nerve entrapment at the elbow at first. An electro physiological diagnosis of an ulnar sensorimotor nerve lesion within the canal of Guyon was made. Magnetic resonance imaging revealed a ganglionic cyst compressing the nerve within the canal, which was confirmed by surgical surgery. Because ulnar nerve entrapment at the wrist is unusual and difficult to detect, it's critical to understand the nerve's anatomical course and distribution so that clinical and electro diagnostic tests can be correct. Electro diagnosis is a useful method for detecting ulnar nerve lesions at the wrist while ruling out other possible causes and detecting concomitant pathology.

Nerve entrapment diseases usually have predictable clinical symptoms and physical examination findings. Imaging can be used to assess a structural source of entrapment, such as a mass or larger muscle, or to reveal secondary signs that corroborate the diagnosis, such as nerve swelling or muscle edoema or atrophy. Entrapment syndromes of the elbow, forearm, and wrist will be discussed in this article.

Neuropathy is a wide word that refers to the clinical presentation of sensory abnormalities (pain, paresthesia, numbness) or motor weakness in the typical distribution of a specific nerve. It can be caused by metabolic or structural problems, such as diabetes. Entrapment syndrome is a type of neuropathy caused by a structural problem with the nerve, such as compression, displacement, or traction, or an intrinsic problem with the nerve, such as a nerve cell malignancy. Imaging is used to identify the abnormality causing the entrapment, such as masses, aberrant muscles, fibrous bands, and osseous deformities, or to show secondary findings that confirm or support the diagnosis.

When compared to the more prevalent site of ulnar nerve entrapment at the elbow, ulnar nerve entrapment at the wrist is uncommon. Electrophysiological and neuroimaging research can help locate and identify different structural sources. Because ulnar neuropathy might be the first sign of a more extensive neuropathy, a thorough clinical and electrophysiological examination is required to rule out a more widespread neuropathy.
