Complete anaesthesia in the cutaneous distribution of the ulnar nerve following submuscular anterior transposition of the ulnar nerve has not been previously reported. We postulate vascular insult as the etiology of this condition and suggest there may be clinical importance to preserving the ulnar nerve blood supply during submuscular anterior...

Causes of ulnar nerve disorders
* Ulnar nerve can be damaged by dislocation or fracture dislocation of the elbow and can be compressed by those who habitually lean on their elbows.
* May be associated with medial epicondylitis (golfer's elbow).
*...

Feindel and Stratford (1958) were the first to use the term cubital tunnel. They emphasized that the ulnar nerve is compressed at the elbow because of anatomic peculiarities to that region. In 1898, Curtis performed the first published case of management for ulnar nerve neuropathy at the elbow, which consisted...

The outcomes of 81 operations were assessed for the treatment of ulnar nerve entrapment at the elbow performed on 55 males (bilateral operations in one) and 25 females
Simple ulnar nerve decompression or anterior transposition of the ulnar nerve (subcutaneous or intramuscular) was performed with or without the operating microscope. Nine...

Neurological symptoms exhibited by patients with rheumatoid arthritis may he due to lesions of the spinal cord, rheumatoid neuropathy or peripheral nerve compression. Cornpression of peripheral nerves in their various anatomical tunnels is well documented, particularly in the upper limb. Compression of the median nerve at the wrist is common in rheumatoid arthritis, but...

Because of the anatomic positioning of the ulnar nerve, it is subject to entrapment and injury by a wide variety of causes. It is the second most common entrapment neuropathy in the upper extremity (the first being the median nerve and its branches). Because of its superficial position at the...

We report a case of ulnar nerve palsy following forearm fracture in a 13-year-old girl. Significant anterior angulation and displacement of the ulna were noted. Operation was performed 3 months after the injury, when no recovery of numbness and claw hand deformity were demonstrated. Intra-operatively the ulnar nerve was found...

A 48-year-old man presented complaining of pain in the right little finger for 2 months, associated with clawing and paresthesia in the ring and little fingers. Physical examination revealed muscular wasting of the interossei and the hypothenar eminence, and grade M3 (MRC classification) weakness isolated to the ulnar-innervated intrinsic muscles of the hand....

Synonym: ulnar neuritis
The ulnar nerve arises from the medial brachial plexus and innervates the muscles of both the forearm and parts of the hand. It also carries sensory neurones supplying the skin of the back of the forearm, the palm and the fourth and little fingers. Most damage to the...

Peripheral nervous system involvement in systemic sclerosis (SSc) is rare, and is usually limited to carpal tunnel syndrome. Ulnar nerve involvement secondary to compression of Guyon's canal has been reported in two patients. Herein, we describe for the first time an SSc patient who developed bilateral ulnar nerve sensorimotor compression...

Wrist pain often proves to be a challenging presenting complaint. Determining the cause of ulnar-sided wrist pain is difficult, largely because of the complexity of the anatomic and biomechanical properties of the ulnar wrist.1, 2 The objectives of this article are to provide an overview of the most common problems that...

We operated on 16 patients for ulnar neuropathy associated with osteoarthritis of the elbow. They were all male manual workers, with an average age of 51 years at the time of surgery. The severity of the symptoms was McGowan grade 1 in five patients, grade 2 in nine and grade...

A 74-year-old female presented with a 3-month history of compression neuropathy of the right ulnar nerve in Guyon's canal. Magnetic resonance imaging and ultrasonography revealed the location of the mass lesion. Surgical exploration discovered a lipoma pressing against both the ulnar nerve and the ulnar artery. The mass was extirpated....

Guyon's canal syndrome, an ulnar nerve entrapment at the wrist, is a well-recognized entity. The most common causes that involve the ulnar nerve at the wrist are compression from a ganglion, occupational traumatic neuritis, a musculotendinous arch and disease of the ulnar artery. We describe two cases of Guyon's canal...

Outcome studies of revision surgical treatment for recurrent or persistent neuropathy of the ulnar nerve at the elbow are relatively rare and none involves patient self-assessment. In this study of 40 patients (41 elbows), a clear discrepancy is shown between clinical assessment and the patient's own view. From clinical assessment,...

We propose our surgical experience and the decisional algorithm we use to select the surgical procedure for the ulnar nerve entrapment at the elbow according to defined parameters.
CONCLUSION: We suggest an algorithm for uniformly treat the patients with cubital tunnel syndrome through a clinical and biological point of view. The...

Ulnar nerve injury following medial wire placement in percutaneous fixation of supraconylar humeral fractures is well recognised. We investigated techniques that may be used to minimise the occurrence and severity of nerve lesions when using percutaneous methods. 4 sheep post euthanasia had K-wires passed through percutaneous nerves before fixation to...

We examined prospectively 37 acromegalic patients with no history of polyneuropathy, acute trauma at the elbow, no diabetes or hypothyroidism with clinical examination, nerve conduction studies (NCS), and high-resolution ultrasound (US).
In 8 of 37 patients, a diagnosis of UCT was made at the beginning of the study reflecting a...

Diabetic mononeuropathies may be non-compressive (cranial nerve lesions, thoraco-abdominal radiculopathy) or compressive giving rise to nerve entrapment syndromes.[1] Compression mononeuropathies are related to mechanical disruption of the myelin sheaths at sites of external compression. Carpal tunnel syndrome affecting the median nerve is the most common but ulnar and lateral popliteal...

A 71-year-old woman presented with a mass on the ulnar aspect of her distal forearm. This mass had been slowly increasing in size over the last 3 years. It was otherwise asymptomatic. Surgical exploration revealed a neurilemoma arising from the ulnar nerve

Certain key elements play crucial roles in tendon transfer operations. Three important principles should be emphasized. First, the transfer should not significantly decrease the remaining function of the hand. Second, the transfer should not create a deformity if significant return of function occurs following a nerve repair. Third, the transfer...
