Three-section thumb deformity

Three-section thumb deformity, as the name implies, has three phalanxes. The three-section thumb deformity can occur alone or concurrently with polydactyly or other congenital malformations. The three-section thumb is divided into two types. The first type has extra knuckles of different shapes, which can be triangular, trapezoidal or rectangular, but the appearance of the thumb is relatively normal, often with lateral deviation. The second type is considered to be the absence of the thumb and the index finger polydactyly. Treatment method: Osteotomy can be used for type 1 three-section thumb deformity, which preserves the functional joints, fuses joints with small mobility, shortens the thumb and corrects the line of force. For two-type three-section thumbs, thumb surgery is required to reconstruct thumb function. A type three thumb before and after surgery. After the postoperative care, the dressing was changed regularly, the stitches were removed in 2 weeks, the Kirschner wire was fixed for 4-6 weeks, and the hands were rehabilitated.


Short paring malformation is a series of congenital developmental abnormalities including dysplasia or loss of fingers and forearms. The clinical manifestations vary greatly, from the short phalanx of the middle section to the absence of the central column, and even the absence of the whole hand. Including the lateral absence of fingers, the presence of meatball-like finger traces on the extremities, which may include part of nails, bone tissue or cartilage. Clinical classification: I: There is no bone defect in the whole hand of the three-finger type, and the individual phalanx is short; II: There is a defect of the phalanx in one or more fingers of the two-finger type; III: One or more fingers of the single-finger type Only one phalanx VI: No phalanx type One or more fingers missing three phalanx V: No metacarpal type One or more finger column metacarpal and three phalanx missing VI: No carpal type All finger series missing part or all Absence of carpal bones VII: Congenital forearm amputation type. The distal part of the forearm is absent, and the stump of the limb usually has dysplasia. The treatment method depends on the degree of finger developmental disorder. The thumb and fingers are mildly dysplastic, and the function is still good. I don’t need treatment. For incomplete and deformed fingers, separate fingers are performed. Severe dysplasia, lack of thumb or finger, free toe bone transplantation, free toe transplantation with blood supply, or finger lengthening can be performed. The patient showed a lack of middle ring little finger before the operation, and a ball-like residue was visible on the fingertip. There was no bone support at the distal end. Free toe bone transplantation of the foot was performed. The appearance of the finger and foot after the operation. Before operation, x-ray showed dysplasia of the thumb and middle ring little finger, no bone support at the distal end, x-ray after free toe transplantation of thumb and middle finger

The knuckles are stiff and painful, suggesting what disease? Doctor: It may be the signal of 4 kinds of diseases, quick cure

In daily life, we need to use fingers to hold chopsticks, hold a pen to write, watch a mobile phone, make a phone call, or type on a computer. In addition to the thumb with 2 knuckles, each finger has 3 knuckles, among which there are abundant blood vessels and tendon sheaths to maintain flexible movement and coordination of the fingers to complete our daily movements. Due to the high frequency of use, with our age and the influence of various factors, the fingers will inevitably develop lesions, and one of the most common manifestations is the stiffness and pain of the joints. When this happens, it will suggest what disease What? The stiffness of the knuckles may be the signal of these four diseases 1. Joint injury In daily life, it is inevitable that bumping accidents will occur, such as the vertical impact of the finger during exercise, or accidentally being caught by the door, It will cause damage to the finger joints, not only causing redness, swelling and pain in the finger joints, but also causing stiffness and restricted movement. It is actually not difficult to diagnose, usually with a relatively clear history of recent trauma, but we must also pay attention to exclude the possibility of closed finger fractures. 2. Gouty arthritis This is a joint inflammation caused by long-term hyperuricemia caused by the deposition of urate crystals on the joints and soft tissues around the joints. The lesions usually occur in the small joints of the hands and feet, which can cause local redness, swelling, and heat in the joints. , Pain and stiffness, the progression of the disease will also lead to joint deformation, which seriously affects finger movement and function. 3. The clinical manifestations of rheumatoid arthritis and gouty arthritis are relatively similar, so it is sometimes difficult to identify, but rheumatoid arthritis occurs more frequently in the hand, and the patient’s uric acid is generally normal. When the weather changes, it is rainy Or it may cause acute attacks after cold, and there may be redness, swelling and pain of the knuckles, and the symptoms of joint stiffness when getting up in the morning, and the joints will deform when the disease progresses. 4. Tenosynovitis Tenosynovitis is caused by excessive movement of the finger and excessive friction of the tendon sheath, causing edema and exudation of the tendon sheath, resulting in chronic fibrous connective tissue hyperplasia, hypertrophy or adhesion changes, which can cause pain in the flexion and extension of the finger, joint swelling and stiffness, and limited flexion and extension At the later stage of the disease, there will also be a noise when joint activity occurs. This kind of situation is more common in IT occupations or people who need to use the computer for a long time. Summary The above refers to the common causes of joint pain and stiffness. Of course, there are physiological factors such as degenerative joint degeneration in the elderly and osteoporosis in the elderly. Joint stiffness and stiffness may also occur, so the cause must be clarified before symptomatic treatment . Finally, it is particularly important to remind everyone that we are living in the information age today and spend a lot of time on mobile phones or computers. At the same time, our finger joints need to continue to work, which puts considerable pressure and load on the knuckles. It is also easy to induce lesions in the finger joints, so we must pay attention to reducing excessive joint activity and taking appropriate rest! References: 1. Gui Guanghua, Wu Fayin, Yu Yougao.

“Calluses” in the wrong place

One day, I suddenly found a “callus” on the finger joints, not on the palms of the hands and feet, nor on the fingertips, but on the back. It was quiet without pain and itching, but it made some people think more and more wrong, so came to the dermatology department for answers! At first glance, the doctor was really not calluses (callos), scientific name knuckle pads. Although the name is unfamiliar, isn’t it quite graphic? Human fingers have three phalanges, so each finger has two interphalangeal joints, called the proximal interphalangeal joint and the distal interphalangeal joint. This phalanx pad is best found in the proximal interphalangeal joints, a few occur in the distal or toes (interphalangeal joints), and extreme restlessness can also be seen in the knee. Disturbance anyway: The above text finds an obvious fallacy, “A human finger has three phalanges”? Leaving aside congenital malformations and acquired traumatic disabilities, at least our most important thumb is dissatisfied, thick and strong with only two joints, so there is only one interphalangeal joint. The next description will still use “general” and “majority” to reflect objectively! Closer to home. This knuckle pad usually shows flat or raised horny hyperplasia, which is harder to touch than normal skin, a little hairy and rough, the color is close to normal skin color, and some are grayish brown or dark reddish brown. Because there is no obvious feeling, many people can’t remember when they started growing. It is clinically necessary to distinguish between calluses and artificial dermatitis. Calluses (calloss) are clearly caused by mechanical friction, which is a physical skin disease. It is more common in palm and plantar friction parts. It is hypertrophic but has normal skin lines. It is related to occupational labor and plays a local protective role. Artificial dermatitis is “made” by yourself, so that you have more peculiar patterns and scars on your body, which is a mental related skin disease. It is difficult for ordinary people to understand, “the body is skinned, the parent is affected”, how can he be so cruel to himself! The cause of the knuckle pads is not clear, some are related to heredity, and may have a family history. Its special site helps to distinguish it from other skin diseases. The pathological manifestations are horny hyperplasia, hypertrophy of spinous layer and thickening of dermal collagen. It’s so ugly, can you cut it? As the so-called “hands up and down, clean and neat”! Slowly, this site cannot be easily cut, otherwise the scars after surgery will be higher and more ugly than the phalanx pads. If it is not good, it will affect the function. Whether it is the knee or the inter-finger joints, the joints are difficult to stay still for a few months, which affects normal skin repair and can only be filled quickly by granulation tissue and new blood vessels. This quick defective product does not have normal skin structure, including appendages such as hair follicle sweat glands We call it scar healing. In the treatment, thiosalam or compound benzoic acid ointment can be applied outside during the day, and retinoid acid cream can be applied externally at night to soften and exfoliate keratin. Fujining plaster can also be tried to increase skin hydration through the package, which is conducive to drug penetration and at the same time plays a protective role. Moisturizing and activating blood circulation such as urea cream and Xiluotuo have improved some people. Finally, we must emphasize daily skin care. The hand is our second face, don’t put a lot of cosmetics on the face, but the hand is not waiting to be seen. Avoid local irritation, including excessive cleaning and some contact chemicals. Use simple moisturizers. Even if it’s not a slim hand, at least it can’t expose the age like old bark! Scientific skin care, let us work hard together! The corns of calluses and calluses.
