Knock Knee Correction Surgery
Knock Knee Correction Surgery samer kareem 5,270 意见 • 2 年 前

Here is how surgeons perform knock knee correction surgery. Titanium plate is used to stabilize the affected area. The femur is cut nearly through to help with the stability. Spreaders angle the cut align the leg. The plate is secured with several screws. Synthetic bone graft material is packed in the joint. The patient will be in crutches for 4 to 6 weeks.

Correction of knock knee deformity
Correction of knock knee deformity samer kareem 1,890 意见 • 2 年 前

This is a technique of correcting knock knee (genu valgum) deformity by surgery. Highligh of the technique is that the bone is not cut, but merely weakened. The advantage is that it provides accuracy to the surgeon, and rapid healing. Once corrected, the bone is held in place with a special plate (Tomofix), which permits walking with crutches the very next day.

Primary biliary cholangitis
Primary biliary cholangitis samer kareem 1,673 意见 • 2 年 前

Primary biliary cholangitis (PBC), formerly known as primary biliary cirrhosis, is a chronic liver disease resulting from progressive destruction of the bile ducts in the liver – called the intrahepatic bile ducts. Bile produced in your liver travels via these ducts to your small intestine where it aids in the digestion of fat and fat-soluble vitamins (A, D, E and K). When the ducts are destroyed, bile builds up in the liver contributing to inflammation and scarring (fibrosis). Eventually this can lead to cirrhosis and its associated complications, as scar tissue replaces healthy liver tissue and liver function becomes increasingly impaired.

An omphalocele is a birth defect in which an infant's intestine or other abdominal organs are outside of the body because of a hole in the belly button (navel) area. The intestines are covered only by a thin layer of tissue and can be easily seen.

Genital Or Oral Herpes
Genital Or Oral Herpes samer kareem 3,432 意见 • 2 年 前

HSV-1 causes "cold sores" on the mouth, and up to 80% of the population has this virus. However, HSV-1 may also be transmitted to the genitals through oral/genital sex and about 40% of genital herpes is caused by HSV-1. Up to 22% of sexually active adults have genital herpes caused by HSV-2.

Is A Condom 100% Safe? samer kareem 1,172 意见 • 2 年 前

No condom prevents pregnancy or sexually transmitted diseases (STDs) 100% of the time. But if you and your partner are having sex, nothing protects against STDs better than a properly used condom. For those having sex, condoms must always be used to protect against STDs even when using another method of birth control.

Retina Laser Surgery
Retina Laser Surgery samer kareem 1,433 意见 • 2 年 前

Most retinal tears need to be treated by sealing the retina to the back wall of the eye with laser surgery or cryotherapy (a freezing treatment). Both of these procedures create a scar that helps seal the retina to the back of the eye. This prevents fluid from traveling through the tear and under the retina, which usually prevents the retina from detaching. These treatments cause little or no discomfort and may be performed in your ophthalmologist’s office. With laser surgery, your ophthalmologist uses a laser to make small burns around the retinal tear. The scarring that results seals the retina to the underlying tissue, helping to prevent a retinal detachment.

Aortoiliac Occlusive Disease
Aortoiliac Occlusive Disease samer kareem 1,668 意见 • 2 年 前

Aortoiliac occlusive disease (AIOD) occurs commonly in patients with PAD. Significant lesions in the aortoiliac arterial segment are exposed easily by palpation of the femoral pulses. Any diminution of the palpable femoral pulse indicates that a more proximal obstruction exists. Obstructive lesions may be present in the infrarenal aorta, common iliac, internal iliac (hypogastric), external iliac, or combinations of any or all of these vessels. Occasionally, degenerated nonstenotic atheromatous disease exists in these vessels and may manifest by atheroembolism to the foot, the "blue toe" or "trash foot" syndrome. Generally, patients with aortoiliac PAD have a poorer general prognosis than those with more distal PAD.

Basal Joint Arthroscopic Debridement
Basal Joint Arthroscopic Debridement samer kareem 1,200 意见 • 2 年 前

The procedure was performed under wrist block regional anesthesia with tourniquet control. A single Chinese finger trap was used on the thumb with 5 to 8 lb of ongitudinal traction. The arm was held down with wide tape around the tourniquet securing it to the hand table to serve as countertraction. A shoulder holder, rather than a traction tower, was used to facilitate fluoroscopic intervention more easily. The Trapeziometacarpal joint was detected by palpation. Joint distension was achieved by injecting 1 to 3 mL of normal saline (Fig. 1). It is important to distally direct the needle approximately 20 degrees to clear the dorsal flare of the metacarpal base and enter the joint capsule. This course should be reproduced upon entering with arthroscopic sleeve/ trocar assembly to minimize iatrogenic cartilage injury. Fluid distention is important to facilitate this. The incision for the 1-R (radial) portal, used for proper assessment of the dorsoradial ligament, posterior oblique ligament, and ulnar collateral ligament, was placed just volar to the abductor pollicis longus tendon. The incision for the 1-U (ulnar) portal, for better evaluation of the anterior oblique ligament and ulnar collateral ligament, was made just ulnar to the extensor pollicis brevis tendon. A short-barrel, 1.9-mm, 30- degree inclination arthroscope was used for complete visualization of the CMC joint surfaces, capsule, and ligaments, and then appropriate management was done, as dictated by the stage of the arthritis detected (Fig. 2A). A full-radius mechanical shaver with suction was used in all the cases, particularly for initial debridement and visualization. Most of the cases were augmented with radiofrequency ablation to perform a thorough synovectomy and radiofrequency was also used to perform chondroplasty in the cases with focal articular cartilage wear or fibrillation. Chondroplasty refers to thedebridement of the fibrillated cartilage to improve vascularity of the cartilage and enhance the growth of fibrocartilage. Ligamentous laxity and capsular attenu- ation were treated with thermal capsulorraphy using a radiofrequency shrinkage probe. We were careful to avoid thermal necrosis; hence, a striping technique was used to tighten the capsule of the lax joints. The striping technique refers to thermal shrinkage performed in longitudinal stripes on the lax capsule, so as to leave vascular zones between the stripes; hence, thermal necrosis is prevented. Arthroscopic stage I disease was characterized by synovitis without any cartilage wear, wherein a synovectomy coupled with thermal capsulor- raphy as described was performed.

Proximal femur & Hip Fixation
Proximal femur & Hip Fixation samer kareem 2,356 意见 • 2 年 前

The lateral approach is used for insertion of fixation devices after closed reduction of a proximal femoral fracture. Reduction of a displaced fracture is usually done with a fracture table, or alternatively a large distractor spanning the hip joint. After satisfactory reduction is confirmed by image intensifier, the lateral approach can be used for insertion of a sliding hip screw or multiple screws. The approach provides limited access to the lateral surface of the femur sufficient for hardware placement. The incision can be extended proximally to accommodate a trochanteric stabilizing plate (TSP), or even anteriorly so that it becomes an anterolateral approach with direct, although limited, access to the femoral neck.

There is any chance that the snake is venomous The person has difficulty breathing There is loss of consciousness If you know the snake is not venomous, treat as a puncture wound. 1. Note the Snake's Appearance Be ready to describe the snake to emergency staff. 2. Protect the Person While waiting for medical help: Move the person beyond striking distance of the snake. Have the person lie down with wound below the heart. Keep the person calm and at rest, remaining as still as possible to keep venom from spreading. Cover the wound with loose, sterile bandage. Remove any jewelry from the area that was bitten. Remove shoes if the leg or foot was bitten. Do not: Cut a bite wound Attempt to suck out venom Apply tourniquet, ice, or water Give the person alcohol or caffeinated drinks or any other medications

Development of atherosclerosis
Development of atherosclerosis samer kareem 1,591 意见 • 2 年 前

Atherosclerosis is a process in which blood, fats such as cholesterol, and other substances build up on your artery walls. Eventually, deposits called plaques may form. The deposits may narrow — or block — your arteries. These plaques can also rupture, causing a blood clot.
