Ulnar clubhand is much less common than radial clubhand and is more appropriately referred to as ulnar deficiencies of the forearm. Most cases are sporadic in occurrence, although genetic syndromes are associated with ulnar dysplasia. Focal dermal hyperplasia, or Goltz syndrome (also known as Goltz-Gorlin syndrome), is an X-linked dominant...

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...

This study retrospectively evaluated the effectiveness of an open reduction and internal fixation of a tension band wiring technique for treating displaced or unstable comminuted distal ulnar shaft fractures without a radial fracture. Ten patients were treated for an isolated distal ulnar shaft fracture. There were 6 cases of a...

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...

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).
*...

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...

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....

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...

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...

Ulnar variance refers to the relative lengths of the radius and ulna, specifically with regard to adjoining articular surfaces of the distal ulna and radius.� The styloid (or lateral) side of the radius normally projects more distal than does the ulna; however the distal radial articular surface is normally tilted...

Many cases of work related compression neuropathy of the ulnar and median nerves at the wrist have been described. This report presents a case of bilateral distal neuropathy of the median and ulnar nerves in a parquet floorer, who laid wooden block flooring by hand and used the palms and...

Indication
ORIF, treatment of delayed union or nonunion ulnar fractures.
Osteotomy of the ulna.
Treatment of chronic osteomyelitis.
Ulnar lengthening (in Kienbock's disease).
Ulnar shortening (in cases of distal radial malunion).
Advantage
Simplest approaches of all forearm, uncovering the entire length of ulna.

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...

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....

Anatomy:
- Tunnel V:
- overlies distal ends of radioulnar articulation on dorsum of wrist, contains EDM;
- Tunnel VI:
- in groove between the...

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 carried out a prospective randomised study comparing medial epicondylectomy with anterior transposition for the treatment of ulnar neuropathy at the elbow. The mean follow-up period was 4.5 years and we assessed the patients neurologically and orthopaedically. Neither procedure appeared to have a significant effect on elbow function. Our study...

Thrombosis of the ulnar artery can be a cause of significant morbidity. Most often a consequence of blunt trauma to the hypothenar eminence of the hand, it may be attributable to one traumatic event or to repetitive insults. Surgery is often required. We reviewed the presentation and diagnosis of ulnar...

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...

The Essex-Lopresti syndrome may develop after a proximal radial fracture such as a radial head fracture, excision of the radial head for fracture, or a displaced proximal radial shaft fracture. The Essex-Lopresti syndrome results when such a fracture, associated with disruption of the forearm interosseous membrane, allows proximal migration...

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...

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...
