Scaphoid Fracture
A scaphoid fracture is a bone fracture, 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 Anatomical snuff box, 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 radiography, 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 magnetic resonance imaging, 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 Orthopedic cast, cast is generally suffi ...

Hand Surgery
Hand surgery deals with both surgical and non-surgical treatment of conditions and problems that may take place in the hand or upper extremity (commonly from the tip of the hand to the shoulder), American Society for Surgery of the Hand. Retrieved on 2011-02-24. including injury and infection. Hand surgery may be practiced by post graduates of orthopedic surgery and plastic surgery and MCh Hand surgery. Plastic surgeons and orthopedic surgeons receive significant training in hand surgery during their residency training. Also, some graduates do an additional one-year hand fellowship. Board certified general, plastic, or orthopedics surgeons who have completed approved fellowship training in hand surgery and have met a number of other practice requirements are qualified to take the "Certificate of Added Qualifications in Surgery of the Hand" examination, formerly known as the CAQSH, it is now known as the SOTH." Now super speciatity training called MCh Hand Surgery required to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nonunion
Nonunion is permanent failure of healing following a broken bone unless intervention (such as surgery) is performed. A fracture with nonunion generally forms a structural resemblance to a fibrous joint, and is therefore often called a "false joint" or pseudoarthrosis (from Greek '' pseudo-'', meaning false, , meaning joint, and '' -osis'', meaning abnormal condition). The diagnosis is generally made when there is no healing between two sets of medical imaging, such as X-ray or CT scan. This is generally after 6–8 months.Page 542 in: Nonunion is a serious complication of a fracture and may occur when the fracture moves too much, has a poor |
Scaphoid
The scaphoid bone is one of the carpal bones of the wrist. It is situated between the hand and forearm on the thumb side of the wrist (also called the lateral or radial side). It forms the radial border of the carpal tunnel. The scaphoid bone is the largest bone of the proximal row of wrist bones, its long axis being from above downward, lateralward, and forward. It is approximately the size and shape of a medium cashew nut. Structure The scaphoid is situated between the proximal and distal rows of carpal bones. It is located on the radial side of the wrist, adjacent to the styloid process of the radius. It articulates with the radius, lunate, trapezoid, trapezium, and capitate. Over 80% of the bone is covered in articular cartilage. Bone The palmar surface of the scaphoid is concave, and forming a distal tubercle, giving attachment to the transverse carpal ligament. The proximal surface is triangular, smooth and convex. The lateral surface is narrow and gives attachm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrist Osteoarthritis
Wrist osteoarthritis is gradual loss of articular cartilage and hypertrophic bone changes (osteophytes). While in many joints this is part of normal aging (senescence), in the wrist osteoarthritis usually occurs over years to decades after scapholunate interosseous ligament rupture or an unhealed fracture of the scaphoid. Characteristic symptoms including pain, deformity and stiffness. Pain intensity and incapability (limited function) are notably variable and do not correspond with arthritis severity on radiographs. Osteoarthritis of the wrist can be idiopathic, but it is mostly seen as a post-traumatic condition. There are different types of post-traumatic osteoarthritis. Scapholunate advanced collapse (SLAC Wrist, SLAC) is the most common form, followed by scaphoid non-union advanced collapse (SNAC). Other post-traumatic causes such as intra-articular fractures of the distal Radius (bone), radius or ulna can also lead to wrist osteoarthritis, but are less common. Types SLAC ...

Avascular Necrosis
Avascular necrosis (AVN), also called osteonecrosis or bone infarction, is death of bone tissue due to interruption of the blood supply. Early on, there may be no symptoms. Gradually joint pain may develop, which may limit the person's ability to move. Complications may include collapse of the bone or nearby joint surface. Risk factors include bone fractures, joint dislocations, alcoholism, and the use of high-dose steroids. The condition may also occur without any clear reason. The most commonly affected bone is the femur (thigh bone). Other relatively common sites include the upper arm bone, knee, shoulder, and ankle. Diagnosis is typically by medical imaging such as X-ray, CT scan, or MRI. Rarely biopsy may be used. Treatments may include medication, not walking on the affected leg, stretching, and surgery. Most of the time surgery is eventually required and may include core decompression, osteotomy, bone grafts, or joint replacement. About 15,000 cases occur per year ...

Lister's Tubercle
Lister's tubercle or dorsal tubercle of radius is a bony prominence located at the distal end of the radius. It is palpable on the dorsum of the wrist. Structure Lister's tubercle is found on the dorsal distal radius. It varies in size and shape significantly. It can range from around 2 to 6 mm in height (averaging 3 mm), and around 6 to 26 mm in length (averaging 13 mm). Lister's tubercle consists of two peaks including radial peak and ulnar peak. Function Lister's tubercle serves as a pulley for the tendon of extensor pollicis longus, which wraps around the medial side and takes a 45° turn. Clinical significance Lister's tubercle is used as a useful landmark during wrist arthroscopy and other wrist surgery. It is palpable on the dorsum of the wrist. It is often difficult to clearly distinguish with radiography. Hyperextension of the wrist can lead to fracture Fracture is the appearance of a crack or complete separation of an object or material int ...

A decorative box is a form of packaging that is generally more than just functional, but also intended to be decorative and artistic. Many such boxes are used for promotional packaging, both commercially and privately. Historical objects are usually called caskets if larger than a few inches in more than one dimension, with only smaller ones called boxes. Gift box Traditionally gift boxes used for promotional and seasonal gifts are made from sturdy paperboard or corrugated fiberboard. These boxes normally consist of a base and detachable lid and are made by using a die cutting process to cut the board. The box is then covered with decorative paper. Gift boxes can be dressed with other gift packaging material, such as decorative ribbons and gift tissue paper. Work box The most common type of decorative box is the feminine work box. It is usually fitted with a tray divided into many small compartments for needles, reels of silk and cotton, and other necessaries for stitchery. T ...

Carpal Bones
The carpal bones are the eight small bones that make up the wrist (carpus) that connects the hand to the forearm. The terms "carpus" and "carpal" are derived from the Latin wikt:carpus#Latin, carpus and the Greek language, Greek wikt:καρπός#Ancient Greek, καρπός (karpós), meaning "wrist". In human anatomy, the main role of the carpal bones is to joint, articulate with the radius (bone), radial and ulnar heads to form a highly mobile condyloid joint (i.e. wrist joint),Kingston 2000, pp 126-127 to provide attachments for thenar and hypothenar muscles, and to form part of the rigid carpal tunnel which allows the median nerve and tendons of the anterior compartment of the forearm, anterior forearm muscles to be transmitted to the hand and fingers. In tetrapods, the carpus is the sole cluster of bones in the wrist between the radius (bone), radius and ulna and the metacarpus. The bones of the carpus do not belong to individual fingers (or toes in quadrupeds), whereas those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
