Closed Reduction of a Distal Radius Fracture
Closed Reduction of a Distal Radius Fracture samer kareem 18,564 意见 • 2 年 前

Closed Reduction of Distal Radius Fractures - Discussion: (distal radius fracture menu) - closed reduction & immobilization in plaster cast remains accepted method of treatment for majority of stable distal radius frx; - unstable fractures will often lose reduction in the cast and will slip back to the pre-reduction position; - patients should be examined for carpal tunnel symptoms before and after reduction; - carpal tunnel symptoms that do not resolve following reduction will require carpal tunnel release; - cautions: - The efficacy of closed reduction in displaced distal radius fractures. - Technique: - anesthesia: (see: anesthesia menu) - hematoma block w/ lidocaine; - w/ hematoma block surgeon should look for "flash back" of blood from hematoma, prior to injection; - references: - Regional anesthesia preferable for Colles' fracture. Controlled comparison with local anesthesia. - Neurological complications of dynamic reduction of Colles' fractures without anesthesia compared with traditional manipulation after local infiltration anesthesia. - methods of reduction: - Jones method: involves increasing deformity, applying traction, and immobilizing hand & wrist in reduced position; - placing hand & wrist in too much flexion (Cotton-Loder position) leads to median nerve compression & stiff fingers; - Bohler advocated longitudinal traction followed by extension and realignment; - consider hyper-extending the distal fragment, and then translating it distally (while in extended position) until it can be "hooked over" proximal fragment; - subsequently, the distal fragment can be flexed (or hinged) over the proximal shaft fragment; - closed reduction of distal radius fractures is facilitated by having an assistant provide counter traction (above the elbow) while the surgeon controls the distal fragment w/ both hands (both thumbs over the dorsal surface of the distal fragment); - flouroscopy: - it allows a quick, gentle, and complete reduction; - prepare are by prewrapping the arm w/ sheet cotton and have the plaster or fibroglass ready; - if flouroscopy is not available, then do not pre-wrap the extremity w/ cotton; - it will be necessary to palpate the landmarks (outer shaped of radius, radial styloid, and Lister's tubercle, in order to judge success of reduction; - casting: - generally, the surgeon will use a pre-measured double sugar sugar tong splint, which is 6-8 layers in thickness; - more than 8 layers of plaster can cause full thickness burns: - reference: Setting temperatures of synthetic casts. - position of immobilization - follow up: - radiographs: - repeat radiographs are required weekly for 2-3 weeks to ensure that there is maintenance of the reduction; - a fracture reduction that slips should be considered to be unstable and probably require fixation with (pins, or ex fix ect.) - there is some evidence that remanipulation following fracture displacement in cast is not effective for these fractures; - ultimately, whether or not a patient is satisfied with the results of non operative treatment depends heavily on th

Excision of mesenteric cyst
Excision of mesenteric cyst samer kareem 9,338 意见 • 2 年 前

Mesenteric cyst is one of the rarest abdominal tumours, with approximately 820 cases reported since 1507. The incidence varies from 1 per 100,000 to 250,000 admissions. The lack of characteristic clinical features and radiological signs may present great diagnostic difficulties.

Eyelid Surgery (Blepharoplasty): What You Need to Know ?
Eyelid Surgery (Blepharoplasty): What You Need to Know ? samer kareem 4,210 意见 • 2 年 前

Blepharoplasty (BLEF-uh-roe-plas-tee) is a type of surgery that repairs droopy eyelids and may involve removing excess skin, muscle and fat. As you age, your eyelids stretch, and the muscles supporting them weaken. As a result, excess fat may gather above and below your eyelids, causing sagging eyebrows, droopy upper lids and bags under your eyes. Besides making you look older, severely sagging skin around your eyes can reduce your side vision (peripheral vision), especially the upper and outer parts of your field of vision. Blepharoplasty can reduce or eliminate these vision problems and make your eyes appear younger and more alert. To help decide if blepharoplasty is right for you, find out what you can realistically expect and explore the benefits and risks of blepharoplasty.

Emphysema
Emphysema samer kareem 3,081 意见 • 2 年 前

Emphysema gradually damages the air sacs (alveoli) in your lungs, making you progressively more short of breath. Emphysema is one of several diseases known collectively as chronic obstructive pulmonary disease (COPD). Smoking is the leading cause of emphysema. Your lungs' alveoli are clustered like bunches of grapes. In emphysema, the inner walls of the air sacs weaken and eventually rupture — creating one larger air space instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream. When you exhale, the damaged alveoli don't work properly and old air becomes trapped, leaving no room for fresh, oxygen-rich air to enter. Treatment may slow the progression of emphysema, but it can't reverse the damage.

Ventricular Septal Defect device closure
Ventricular Septal Defect device closure samer kareem 30,209 意见 • 2 年 前

A ventricular septal defect (VSD) is an opening or hole in the wall that separates the two lower chambers of the heart. This wall is called the ventricular septum. The hole causes oxygen-rich blood to leak from the left side of the heart to the right side. This causes extra work for the right side of the heart, since more blood than necessary is flowing through the right ventricle to the lungs.

Shoulder Nerve injury
Shoulder Nerve injury samer kareem 2,957 意见 • 2 年 前

The shoulder and arm receives its nerve supply through the brachial plexus. The brachial plexus is a complex network of nerves which come out of the neck, passes down to the front of the shoulder and then splits into many separate nerves to travel to different muscles and parts of the skin. Normally an arm movement is produced by initially thinking of the movement, then a message passes from the brain, down through the spinal cord to the appropriate nerve. Then the instruction to move is conveyed along the nerve to the specific arm muscle which then contracts and moves the arm.
