Palmar dislocation of the proximal interphalangeal joint--an injury not to be missed. (1/170)
Palmar dislocations of the proximal interphalangeal (PIP) joint are associated with long term complications if suboptimally treated. Six cases of palmar dislocation of the PIP joint are presented and a systematic approach in the diagnosis and management of such injuries in the accident and emergency department is described. (+info)Isolation of Pantoea agglomerans in two cases of septic monoarthritis after plant thorn and wood sliver injuries. (2/170)
Arthritis after plant injury is often apparently aseptic. We report two cases due to Pantoea agglomerans. In one case, the bacterium was isolated only from the pediatric blood culture media, BACTEC Peds Plus, monitored in BACTEC 9240, and not from the other media inoculated with the joint fluid. This procedure could help improve the diagnosis of septic arthritis. (+info)Childhood finger injuries and safeguards. (3/170)
OBJECTIVE: To understand the epidemiology, sites, and mechanism of finger injuries in children and to consider safety measures. SETTING: Accident and emergency department of a children's hospital in Glasgow. METHODS: A prospective study was carried out with a specifically designed questionnaire. Altogether 283 children presenting with isolated finger injuries were identified over six months. Available safety measures to avoid or reduce damage from such injuries were considered. RESULTS: Finger injuries were common (38%) in those under 5 years. Most of these occurred at home (59%), commonly (48%) because of jamming between two closeable opposing surfaces, and mostly (79%) in doors at home and school. The doors were commonly (85%) closed by someone and often (60%) by a child. Sixteen (6%) were treated for amputation. CONCLUSION: Finger injuries are common, especially at the preschool age, and are mostly caused by jammed fingers in doors, at home. Safeguards should be considered according to location, like home or institutions, and expense. (+info)Contribution of lumbrical muscle activity to the paradoxical extension phenomenon induced by injuries to the finger flexor tendons. (4/170)
The "Extensor habitus" phenomenon occurs in finger flexor tendon injuries and consists of a paradoxical extension of the interphalangeal joints after an attempt to flex the finger. The mechanism of extension is considered to be a contraction of the flexor digitorum profundus that is then transmitted via the lumbrical muscle structure to the extensor expansion. Using electromyography, we recorded the lumbrical muscle activity during the paradoxical extension phenomenon to determine whether the lumbrical muscle contributed to this event. Two patterns of electromyographical activity of the lumbrical muscle were observed. Group I (6 fingers) displayed electrical activities in the lumbrical muscle during flexion tasks, while group II (12 fingers) did not. In group I, the lesions were mainly located in zone V, and the response to range of motion exercises was satisfactory. In group II, nearly all of the lesion were located in zone II, and half of the cases required additional surgical interventions. Group II appeared to exhibit the "Extensor habitus" phenomenon, while group I exhibited an "Extensor habitus-like phenomenon." To distinguish between these two phenomena, an electromyographical examination of the lumbrical muscle must be performed. (+info)Comparison of sonography and magnetic resonance imaging for the diagnosis of partial tears of finger extensor tendons in rheumatoid arthritis. (5/170)
OBJECTIVE: Finger extensor tenosynovitis in rheumatoid arthritis (RA) may lead to partial and eventually to complete tendon tears. The aim of this study was to investigate the diagnostic value of sonography (SG) and/or magnetic resonance imaging (MRI) to visualize partial tendon tears. METHODS: Twenty-one RA patients with finger extensor tenosynovitis for more than 12 months underwent SG, MRI and surgical inspection, the latter being the gold standard. RESULTS: For partial tears, sensitivity and specificity were 0.27 and 0.83 for MRI, and 0.33 and 0.89 for SG, respectively. Positive and negative predictive values were 0.35 and 0.78 for MRI, and 0.50 and 0.80 for SG, respectively. Accuracy was 0.69 for MRI and 0.75 for SG. CONCLUSION: For visualization of partial finger extensor tendon tears in RA patients, SG performs slightly better than MRI, but both techniques are at present not sensitive enough to be used in daily practice. (+info)Simultaneous Bennett's fracture and metacarpophalangeal dislocation of the same thumb in a soccer player. (6/170)
Double dislocations of finger joints are rare. An unusual case of a simultaneous Bennett's fracture/dislocation ofthe carpometacarpal joint and a dorsal dislocation of the metacarpophalangeal joint of the same thumb, and the management of this injury are reported. The patient had an excellent functional result. (+info)Percutaneous release of trigger digits. (7/170)
We describe a safe and easy percutaneous technique for release of trigger finger using a specially designed knife. The A1 pulley is sectioned by a blade which has a hooked end. We released, percutaneously, 185 trigger fingers, including 62 which were locked using this technique. Satisfactory results were achieved in 173 (93.5%). There were no significant complications. We recommend this as a safe and effective outpatient procedure for those patients who have not responded successfully to conservative treatment, have longstanding symptoms or severe triggering. (+info)Screening for extensor tendon rupture in rheumatoid arthritis. (8/170)
OBJECTIVE: Surgery can prevent extensor tendon rupture in the rheumatoid wrist but it is difficult to identify patients at risk. Extensor digiti minimi (EDM) usually ruptures first, but rupture may pass unnoticed because extensor digitorum communis (EDC) extends all four fingers simultaneously. We assessed the value of screening for EDM rupture by examining for absent independent extension of the little finger in a hospital rheumatoid arthritis population. METHODS: The EDM test was performed in 550 previously unoperated wrists. Disease activity, joint damage, wrist swelling, tenderness and crepitus were recorded. RESULTS: Unsuspected EDM loss was found in nine of the 550 wrists (1.6%); dorsal synovitis was absent or minimal in eight and ulnar tenderness was absent in six. EDM loss was not associated with activity, severity or duration of disease. CONCLUSIONS: The EDM test is simple and cheap. It may identify patients at risk and permit prophylactic surgery before hand function is lost. (+info)Finger injuries refer to any damage or trauma caused to the fingers, which can include cuts, bruises, dislocations, fractures, and sprains. These injuries can occur due to various reasons such as accidents, sports activities, falls, or direct blows to the finger. Symptoms of finger injuries may include pain, swelling, stiffness, deformity, numbness, or inability to move the finger. The treatment for finger injuries varies depending on the type and severity of the injury, but may include rest, immobilization, ice, compression, elevation, physical therapy, medication, or surgery. It is essential to seek medical attention promptly for proper diagnosis and treatment of finger injuries to prevent further complications and ensure optimal recovery.
A splint is a device used to support, protect, and immobilize injured body parts, such as bones, joints, or muscles. It can be made from various materials like plastic, metal, or fiberglass. Splints are often used to keep the injured area in a stable position, reducing pain, swelling, and further damage while the injury heals. They come in different shapes and sizes, tailored to fit specific body parts and injuries. A splint can be adjustable or custom-made, depending on the patient's needs. It is essential to follow healthcare professionals' instructions for using and caring for a splint to ensure proper healing and prevent complications.
Traumatic amputation is the accidental or spontaneous separation of a limb or body part due to trauma or severe injury. This can occur as a result of motor vehicle accidents, industrial incidents, agricultural mishaps, or military combat, among other causes. The severed portion may or may not be recoverable for reattachment depending on various factors such as the extent of damage, ischemia time, and conditions during transportation. Immediate medical attention is required to control bleeding, manage shock, prevent infection, and initiate appropriate wound care and potential reconstructive surgery.
In medical terms, fingers are not specifically defined as they are common anatomical structures. However, I can provide you with a general anatomy definition:
Fingers are the terminal parts of the upper limb in primates, including humans, consisting of four digits (thumb, index, middle, and ring fingers) and one opposable thumb. They contain bones called phalanges, connected by joints that allow for movement and flexibility. Each finger has a nail, nerve endings for sensation, and blood vessels to supply nutrients and oxygen. Fingers are crucial for various activities such as grasping, manipulating objects, and tactile exploration of the environment.
Zinc fingers are a type of protein structural motif involved in specific DNA binding and, by extension, in the regulation of gene expression. They are so named because of their characteristic "finger-like" shape that is formed when a zinc ion binds to the amino acids within the protein. This structure allows the protein to interact with and recognize specific DNA sequences, thereby playing a crucial role in various biological processes such as transcription, repair, and recombination of genetic material.
A wound is a type of injury that occurs when the skin or other tissues are cut, pierced, torn, or otherwise broken. Wounds can be caused by a variety of factors, including accidents, violence, surgery, or certain medical conditions. There are several different types of wounds, including:
* Incisions: These are cuts that are made deliberately, often during surgery. They are usually straight and clean.
* Lacerations: These are tears in the skin or other tissues. They can be irregular and jagged.
* Abrasions: These occur when the top layer of skin is scraped off. They may look like a bruise or a scab.
* Punctures: These are wounds that are caused by sharp objects, such as needles or knives. They are usually small and deep.
* Avulsions: These occur when tissue is forcibly torn away from the body. They can be very serious and require immediate medical attention.
Injuries refer to any harm or damage to the body, including wounds. Injuries can range from minor scrapes and bruises to more severe injuries such as fractures, dislocations, and head trauma. It is important to seek medical attention for any injury that is causing significant pain, swelling, or bleeding, or if there is a suspected bone fracture or head injury.
In general, wounds and injuries should be cleaned and covered with a sterile bandage to prevent infection. Depending on the severity of the wound or injury, additional medical treatment may be necessary. This may include stitches for deep cuts, immobilization for broken bones, or surgery for more serious injuries. It is important to follow your healthcare provider's instructions carefully to ensure proper healing and to prevent complications.
