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...

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).
*...

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...

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...

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...

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...

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 57-year-old man presented with chronic ulnar-sided right wrist pain. Plain radiographs were nondiagnostic (not shown). We performed magnetic resonance imaging (MRI). Coronal T1-weighted (Fig. 1), coronal fast short tau inversion recovery (Fig. 2) and coronal gradient-refocused acquisition in the steady...

ulnar styloid erosions

Neural traction may be an important cause of cubital tunnel syndrome, according to researchers at the Washington University School of Medicine in St. Louis. To study the etiology of cubital tunnel syndrome (compression of the ulnar nerve at the elbow), 23 upper extremity cadaveric specimens were studied using a combination...

Gamekeeper's thumb was originally described by Campbell in 1955 when he reported chronic laxity of the ulnar collateral ligament (UCL) of the thumb in 24 Scottish gamekeepers. The injury occurred as gamekeepers sacrificed wounded rabbits and other small game by breaking their necks between the ground and their thumbs and...

In his now classic 1962 article, Bertil Stener described a distinct, surgically correctable anatomic lesion that could account for the chronic instability found in the thumbs of some gamekeepers and skiers. CS Campbell first coined the term gamekeeper's thumb in 1955, when he described insufficiency in the ulnar collateral ligament...

In 1981, Palmer and Werner introduced the term "triangular fibrocartilage complex" (TFCC) to describe the ligamentous and cartilaginous structures that suspend the distal radius and ulnar carpus from the distal ulna (see Image 1). The TFCC is the major ligamentous stabilizer of the distal radioulnar joint (DRUJ) and the ulnar...

Injuries to the ulnar collateral ligament (UCL) of the thumb were first recognized as an occupational condition in European gamekeepers. By repetitively wringing the necks of game (eg, chickens) between their thumb and index finger, these workers produced a chronic stretching of the UCL that resulted in instability at the...

Campbell originally coined the term gamekeeper's thumb in 1955,1 because this condition was most commonly associated with Scottish gamekeepers, especially rabbit keepers, in whom the injury was work related. The injury occurred as the men sacrificed game such as rabbits; the animals' necks were broken between the ground and the...
