Dorsal Intercalated Segment Instability
Dorsal intercalated segment instability (DISI) is a deformity of the wrist where the lunate bone angulates to the dorsal side of the hand. Causes The main causes of DISI are: *Wrist trauma, with or without a fracture **Scaphoid fracture: bony DISI **Distal radius fracture: compensatory DISI **Malunion of radius fracture: adaptive DISI *Scapholunate ligament instability The scapholunate ligament is a ligament of the wrist. Rupture of the scapholunate ligament causes scapholunate instability, which, if untreated, will eventually cause a predictable pattern of wrist osteoarthritis called scapholunate advanced coll ...: ligamentous DISI References {{reflist Orthopedics ...

Wrist
In human anatomy, the wrist is variously defined as (1) the Carpal bones, carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; "The wrist contains eight bones, roughly aligned in two rows, known as the carpal bones." (2) the wrist joint or radiocarpal joint, the joint between the radius (bone), radius and the Carpal bones, carpus and; (3) the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of the metacarpus or five metacarpal bones and the series of joints between these bones, thus referred to as ''wrist joints''. "With the large number of bones composing the wrist (ulna, radius, eight carpas, and five metacarpals), it makes sense that there are many, many joints that make up the structure known as the wrist." This region also includes the carpal tunnel, the anatomical snuff box, bracelet lines, the Flexor retinaculum of the hand, flexor retinaculum, and the ex ...

Lunate Bone
The lunate bone (semilunar bone) is a carpal bone in the human hand. It is distinguished by its deep concavity and crescentic outline. It is situated in the center of the proximal row carpal bones, which lie between the ulna and radius and the hand. The lunate carpal bone is situated between the lateral scaphoid bone and medial triquetral bone. Structure The lunate is a crescent-shaped carpal bone found within the hand. The lunate is found within the proximal row of carpal bones. Proximally, it abuts the radius. Laterally, it articulates with the scaphoid bone, medially with the triquetral bone, and distally with the capitate bone. The lunate also articulates on its distal and medial surface with the hamate bone. The lunate is stabilised by a medial ligament to the scaphoid bone and a lateral ligament to the triquetral bone. Ligaments between the radius and carpal bone also stabilise the position of the lunate, as does its position in the lunate fossa of the radius. Bone The pro ...

Radiopaedia
Radiopaedia is a wiki-based international collaborative educational web resource containing a radiology encyclopedia and imaging case repository. It is currently the largest freely available radiology related resource in the world with more than 50,000 patient cases and over 16,000 reference articles on radiology-related topics. The open edit nature of articles allows radiologists, radiology trainees, radiographers, sonographers, and other healthcare professionals interested in medical imaging to refine most content through time. An editorial board peer reviews all contributions. Background Radiopaedia was started as a past-time project to store radiology notes and cases online by the Australian neuroradiologist Associate Professor Frank Gaillard in December 2005, while he was a radiology resident. He later became passionate in building the website and decided to release it on the web, advocating free dissemination of knowledge. The domain name for radiopaedia.org was registered ...

Scaphoid Fracture
A scaphoid fracture is a break of the scaphoid bone in the wrist. Symptoms generally includes pain at the base of the thumb which is worse with use of the hand. The anatomic snuffbox is generally tender and swelling may occur. Complications may include nonunion of the fracture, avascular necrosis of the proximal part of the bone, and arthritis. Scaphoid fractures are most commonly caused by a fall on an outstretched hand. Diagnosis is generally based on a combination of clinical examination and medical imaging. Some fractures may not be visible on plain X-rays. In such cases the affected area may be immobilised in a splint or cast and reviewed with repeat X-rays in two weeks, or alternatively an MRI or bone scan may be performed. The fracture may be preventable by using wrist guards during certain activities. In those in whom the fracture remains well aligned a cast is generally sufficient. If the fracture is displaced then surgery is generally recommended. Healing may take up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distal Radius Fracture
A distal radius fracture, also known as wrist fracture, is a break of the part of the radius bone which is close to the wrist. Symptoms include pain, bruising, and rapid-onset swelling. The ulna bone may also be broken. In younger people, these fractures typically occur during sports or a motor vehicle collision. In older people, the most common cause is falling on an outstretched hand. Specific types include Colles, Smith, Barton, and Chauffeur's fractures. The diagnosis is generally suspected based on symptoms and confirmed with X-rays. Treatment is with casting for six weeks or surgery. Surgery is generally indicated if the joint surface is broken and does not line up, the radius is overly short, or the joint surface of the radius is tilted more than 10% backwards. Among those who are cast, repeated X-rays are recommended within three weeks to verify that a good position is maintained. Distal radius fractures are common, and are the most common type of fractures that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malunion
A malunion is when a fractured bone does not heal properly. Some ways that it shows is by having the bone being twisted, shorter, or bent. Malunions can occur by having the bones improperly aligned when immobilized, having the cast taken off too early, or never seeking medical treatment after the break. Malunions are painful and commonly produce swelling around the area, possible immobilization, and deterioration of the bone and tissue. Signs and symptoms Malunions are presented by excessive swelling, twisting, bending, and possibly shortening of the bone. Patients may have trouble placing weight on or near the malunion. Diagnosis An X-ray is essential for the proper diagnosis of a malunion. The doctor will look into the patient’s history and the treatment process for the bone fracture. Oftentimes a CT scan and probably an MRI are also used in diagnosis. MRI are used to check of cartilage and ligament issues that developed due to the malunion and misalignment. CT scans ar ...

Scapholunate Ligament Instability
The scapholunate ligament is a ligament of the wrist. Rupture of the scapholunate ligament causes scapholunate instability, which, if untreated, will eventually cause a predictable pattern of wrist osteoarthritis called scapholunate advanced collapse (SLAC). Anatomy The scapholunate ligament is an Intercarpal articulations, intraarticular ligament binding the scaphoid bone, scaphoid and lunate bone, lunate bones of the wrist together. It is divided into three areas, Dorsum (anatomy), dorsal, Anatomical terms of location#Proximal and distal, proximal and Anatomical terms of location#Appendages, palmar, with the dorsal segment being the strongest part. It is the main Joint stability, stabilizer of the scaphoid. In contrast to the scapholunate ligament, the lunotriquetral ligament is more prominent on the palmar side. Instability Complete sprain, rupture of this ligament leads to wrist instability. The main type of such instability is dorsal intercalated segment instability (DISI) de ...
