Cubital tunnel syndrome is often accompanied by paresthesia in ulnar nerve sites and hand muscle atrophy. When muscle weakness occurs, or after failure of more conservative treatments, anterior transposition is used. In the present study, the ulnar nerve and its blood vessels were examined in the elbows of 18 adult cadavers, and the external diameter of the nutrient vessels of the ulnar nerve a...

Ulnar tunnel syndrome could be broadly defined as a compressive neuropathy of the ulnar nerve at the level of the wrist. The ulnar tunnel, or Guyon's canal, has a complex and variable anatomy. Various factors may precipitate the onset of ulnar tunnel syndrome. Patient presentation depends on the anatomic zone of ulnar nerve compression: zone I compression, motor and sensory signs and symptoms; ...

OBJECTIVE Earlier studies have shown sonographic enlargement of the ulnar nerve in patients with Hansen's neuropathy. The present study was performed to determine whether sonography or electrophysiological studies can detect the specific site of ulnar nerve pathology in leprosy. METHODS Eighteen patients (thirty arms) with Hansen's disease and an ulnar neuropathy of whom 66% had borderline tu...

Objective: The present study was conducted to assess the involvement of ulnar sensory and/or motor nerve fibers in patients with carpal tunnel syndrome (CTS) and whether this affects the accuracy of the median versus ulnar comparative tests. Patients and methods: The present study included 145 CTS hands and 71 asymptomatic control hands. Clinical examination was done. The following tests were d...

Multiple-bud regeneration, i.e., multiple amplification, has been shown to exist in peripheral nerve regeneration. Multiple buds grow towards the distal nerve stump during proximal nerve fiber regeneration. Our previous studies have verified the limit and validity of multiple amplification of peripheral nerve regeneration using small gap sleeve bridging of small donor nerves to repair large rec...

There is evidence that nerve flaps are superior to nerve grafts for bridging long nerve defects. Moreover, arterialized neurovenous flaps (ANVFs) have multiple potential advantages over traditional nerve flaps in this context. This paper describes a case of reconstruction of a long defect of the ulnar artery and nerve with an arterialized neurovenous free flap and presents a literature review o...

BACKGROUND Medial pinning is one of the most controversial aspects of the surgical treatment of supracondylar fractures (SHF) owing to the risk of ulnar nerve injury. AIM To evaluate the safety and usefulness of medial pinning for SHF using ultrasound imaging for ulnar nerve visualization. METHODS Fifteen children, with a mean age of 60 months, with displaced SHF were treated with a crossed...

Cubital tunnel syndrome refers to ulnar nerve compressive neuropathy and most commonly occurs at the level of the elbow. Surgical options include in situ decompression, decompression with anterior transposition of the ulnar nerve, and medial epicondylectomy with or without decompression. With the advancement of endoscopic surgery, techniques of endoscopic in situ decompression of the ulnar nerv...

Background: Ulnar nerve neuropathy is one of the most common peripheral nerve dysfunctions. Elbow is the most common area affected by ulnar nerve which is mainly because of fractures or dislocations of this area. Delayed ulnar nerve palsy (Tardy Ulnar Nerve Palsy) in children due to a malpositioning of upper extremity during hospitalization is an uncommon cause of ulnar nerve injury which we ha...

Many carpal tunnel syndrome (CTS) patients have symptoms in both the median and ulnar digits more frequently than in the median digits alone. This is possibly because of close anatomical contiguity of the carpal tunnel and Guyon's canal, and the high pressure may also affect the latter, causing indirect compression of ulnar nerve fibers. Thus, we evaluated the functional status of the ulnar ner...
