Basal Joint Arthroscopic Debridement
Basal Joint Arthroscopic Debridement samer kareem 1,206 Views • 2 years ago

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.

Epstein Barr Virus

Epstein-Barr is the virus that causes mononucleosis. You might know this disease better by its nickname, "mono." It's also called the "kissing disease" because of one way you can spread it to someone else. Even though Epstein-Barr virus (EBV) isn't a household name, you've probably been infected without knowing it. Lots of people carry the virus but don't get sick

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

arteriosclerosis
arteriosclerosis samer kareem 1,015 Views • 2 years ago

Atherosclerosis is a narrowing of the arteries caused by a buildup of plaque. It’s also called arteriosclerosis or hardening of the arteries. Arteries are the blood vessels that carry oxygen and nutrients from your heart to the rest of your body. As you get older, fat and cholesterol can collect in your arteries and form plaque. The buildup of plaque makes it difficult for blood to flow through your arteries. This buildup may occur in any artery in your body and can result in a shortage of blood and oxygen in various tissues of your body. Pieces of plaque can also break off, causing a blood clot. Atherosclerosis can lead to heart attack, stroke, or heart failure if left untreated.

At each level of the spine, there is a disc space in the front and paired facet joints in the back. Working together, these structures define a motion segment (Fig. 1A). Back pain may re­sult when injury or degenerative changes allow abnormal movement of the vertebrae to rub against one another, known as an unstable motion segment (Fig. 1B). Two vertebrae need to be fused to stop the motion at one segment. For example, an L4-L5 fusion is a one-level spinal fusion (Fig. 1C). A two-level fusion joins three vertebrae together and so on.

Spina Bifida. NTD samer kareem 1,641 Views • 2 years ago

Spina bifida is a condition that affects the spine and is usually apparent at birth. It is a type of neural tube defect (NTD). Spina bifida can happen anywhere along the spine if the neural tube does not close all the way. When the neural tube doesn’t close all the way, the backbone that protects the spinal cord doesn’t form and close as it should. This often results in damage to the spinal cord and nerves. Spina bifida might cause physical and intellectual disabilities that range from mild to severe. The severity depends on: The size and location of the opening in the spine. Whether part of the spinal cord and nerves are affected.

Plate and screwed fixation of Foot
Plate and screwed fixation of Foot samer kareem 1,626 Views • 2 years ago

A broken bone must be carefully stabilized and supported until it is strong enough to handle the body's weight and movement. Until the last century, physicians relied on casts and splints to support and stabilize the bone from outside the body. The advent of sterile surgical procedures reduced the risk of infection, allowing doctors to internally set and stabilize fractured bones. During a surgical procedure to set a fracture, the bone fragments are first repositioned (reduced) into their normal alignment. They are held together with special implants, such as plates, screws, nails and wires. Internal fixation allows shorter hospital stays, enables patients to return to function earlier, and reduces the incidence of nonunion (improper healing) and malunion (healing in improper position) of broken bones. The implants used for internal fixation are made from stainless steel and titanium, which are durable and strong. If a joint is to be replaced, rather than fixed, these implants can also be made of cobalt and chrome. Implants are compatible with the body and rarely cause an allergic reaction.
