Fractures (Subscribe)  

# mechanism: forced abduction of thumb
# findings:
* intraarticular fracture/dislocation of the base of the 1st metacarpal at the ulnar aspect
* small fragment of metacarpal continues to articulate with the trapezium
* lateral retraction of metacarpal shaft by abductor pollicis longus

In 1882, Edward Hallaran Bennett, MD, described the fracture of the base of the first metacarpal that bears his name. Bennett described the anatomic details of the fracture and suggested that early diagnosis and treatment are imperative to prevent loss of function of this highly mobile joint

most frequent of all thumb frx; - described in 1882 by Dr. Edward Bennet; - it is a frx dislocation, intra-articular frx at base of carpometacarpal joint of the thumb; - involves an oblique intraarticular metacarpal frx (known as the palmar...

Identifying and treating thumb injuries is important as thumb function constitutes 50% of hand function as a whole.

Subcapital fractures of the fifth metacarpal bone, meaning fractures just below the knuckle of the little finger, account for approximately 20% of all hand fractures. Currently, there is no consensus concerning the optimal management of these fractures. Traditionally, treatment consists of closed reduction and external splinting in a neutral position...

We report the unusual case of a horizontal fracture of the metacarpal head, complicated by 90°dorsal rotation about a transverse axis, and extrusion of the head fragment from the joint capsule. We describe our approach to assessment, surgical management and successful restoration of function.

If you think a broken (fractured) finger is a minor injury, think again. Without proper treatment a fractured finger can cause major problems. The bones in a normal hand line up precisely. They let you perform many specialized functions, such as grasping a pen or manipulating small objects in your... Highly Reputable

Notes primarily on Metacarpal fractures.

Phalangeal fractures are common injuries that may significantly affect hand function if not managed appropriately. Closed treatment has been the mainstay of treatment. Percutaneous pinning allowed the conversion of more unstable fracture patterns to stable configurations capable of tolerating early motion. More recently, minifragment screws and plates were developed to...

Hand fractures, a frequent emergency department complaint, are the most common fractures of the body. Proper management at initial evaluation of hand injuries can prevent a significant amount of morbidity and disability. Emergency physicians, often the first to assess these fractures, must have the skills to properly evaluate and manage...

Fractures of the hand can occur in either the small bones of the fingers (phalanges) or the long bones (metacarpals). They can result from a twisting injury, a fall, a crush injury, or direct contact in sports.

The term mallet finger has long been used to describe the deformity produced by disruption of the terminal extensor mechanism at the distal interphalangeal (DIP) joint.1, 2, 3 Mallet finger is the most common closed tendon injury that is seen in athletes; this injury is also common in nonathletes after...

Malunion may be defined as healing of a fracture in an abnormal (nonanatomic) position. In the hand, it presents a combined functional and aesthetic problem. The management of malunion of hand fractures is more complex than the management of malunion of fractures elsewhere in the skeleton. Good hand function depends...
