Congenital deficiency of part of distal ulna affecting the distal radio-ulnar joint is a rare disorder. It is even rarer to find the association of proximal radio-ulnar joint dislocation along with distal ulnar deficiency. This type of congenital forearm anomaly is difficult to treat. Conversion to a single bone forearm in the expense of pronation-supination movement is a viable option. By doin...

Ulnar neuropathy in the region of the elbow is not uncommon, but its association with hypoplasia of the trochlea and the medial epicondyle of the humerus is extremely rare. Probably the earliest description of this association was that of Saito in 1927, but few details of the ulnar neuropathy were given in his report. In 1963 Abematsu, Miyashita and Aoki added three patients with a similar cond...

During the educational dissection of a 72-year-old Chinese male cadaver, bilateral extensor digitorum brevis manus (EDBM) muscles were observed. The left EDBM muscle originated from the joint capsule ligament, running across the second dorsal interosseous muscle as double tendons (EDBM ulnar tendon and EDBM radial tendon) on the ulnar side of extensor digitorum communis (EDC)-index finger. The ...

Ulnar neuropathy at or distal to the wrist, the so-called ulnar tunnel syndrome, is an uncommon but well-described condition. However, diagnosis of ulnar tunnel syndrome can be difficult. Paresthesias may be nonspecific or related to coexisting pathologies, such as carpal tunnel syndrome, cubital tunnel syndrome, thoracic outlet syndrome, C8-T1 radiculopathy, or peripheral neuropathy, which mak...

Ulnar neuropathy at the elbow is the second most frequent entrapment neuropathy and is considered idiopathic in most patients. However, several anatomic variations, including the anconeus epitrochlearis muscle, have been reported to cause ulnar nerve compression. The anconeus epitrochlearis muscle is a common anatomic variation, with a prevalence of up to 34%, but the clinical diagnosis of ulna...

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...

OBJECTIVE The main objective of this study was to describe Martin-Gruber anastomosis anatomically and to recognize its clinical repercussions. METHOD 100 forearms of 50 adult cadavers were dissected in an anatomy laboratory. The dissection was performed by means of a midline incision along the entire forearm and the lower third of the upper arm. Two flaps including skin and subcutaneous tissu...

[Purpose] Ulnar nerve neuropathies are the second most commonly seen entrapment neuropathies of the upper extremities after carpal tunnel syndrome. In this study, we aimed to evaluate pain among ulnar neuropathy patients by the Leeds assessment of neuropathic symptoms and signs pain scale and determine if it correlated with the severity of electrophysiologicalfindings. [Subjects and Methods] We...

Introduction Usually the ulnar artery arises as one of the two terminal branches of brachial artery in the cubital fossa, which in turn gives rise to common interosseous artery in the upper forearm. Ulnar artery continues as superficial palmar arch in the hand by joining with superficial palmar branch of radial artery [1]. The term superficial ulnar artery is given when it arises from axillary ...
