What Is Nerve Ablation Used To Treat
The most common use for nerve ablation knee treatment is knee pain caused by moderate to severe arthritis. Generally, these procedures are performed for those patients who are knee replacement candidates, but who dont want that procedure. They should generally not be used to treat mild arthritis as better options exist for that problem.
What Are The Concerns About Cooled Rf
While cooled RF sounds cool, as discussed, its cooled because the probe can get very hot. At least one expert has chimed in that the high energy used in these procedures means that more tissue damage may occur .
Hence, its important to note that in one study, there was no difference between a numbing shot with steroid around the nerves versus the actual cooled RFA procedure . Meaning a numbing shot without burning the nerve worked as well as killing the nerve.
When Should I Get Medical Care
Because most cuts and scrapes are minor, they can be treated at home using the tips listed above. However, some injuries are more serious.
You should call your health care provider right away or go to the closest emergency room if the wound is:
- Bleeding a lot you cant stop it after of pressure with a bandage or clean cloth
- Very painful
- Ragged around the edges
- Open, wide, or jagged You may need to see a health care provider for a special medical glue, steri-strips, or stitches
- Close to the eye or on the face even a small cut on the face should be checked by a health care provider because of the risk of a scar.
- Caused by a nail, or other sharp, pointy, dirty or rusty object
- Black or brown color from road burn after washing, which means that theres still dirt and tiny rocks in the scrape that you need a health professional to scrub away
- Swelling over a bone or joint
- Caused from an animal or human bite
- Showing signs of
- You should also call your health care provider if you havent had a tetanus vaccination in the past 5 years.

How To Stop Uncontrolled Bleeding
If you encounter someone experiencing uncontrolled bleeding, first make sure you are safe. If you are safe, it’s important to remember that any attempt to control bleeding is better than no intervention.
Next, follow the ABCs of Bleeding:
A – Alert – Call 911
B – Bleeding – Find the source of bleeding. Look on the arms, legs, neck, groin, and abdomen areas for bleeding.
C – Compress Once you find the source of bleeding, apply pressure. You can use a piece of clothing, or anything else available that can help stop bleeding. Cover the wound and apply pressure by pushing directly with both hands. You can also pack the wound with gauze or a clean cloth, and then continue to hold pressure with both hands. If bleeding does not slow or stop, and the injury is located on an arm or leg, a tourniquet can be applied high and tight on the limb to stop the bleeding. Keep holding pressure on the injury until help arrives.
Causes And Types Of Scrapes
Scrapes are skin wounds that rub or tear off skin. Most scrapes are shallow and do not extend far into the skin, but some may remove several layers of skin. Usually there is little bleeding from a scrape, but it may ooze pinkish fluid. Most scrapes are minor, so home treatment is usually all that is needed to care for the wound.
Scrapes occur most often in warm weather or warm climates when the skin on the arms and legs is more exposed. They are most commonly caused by accidents or falls but can occur anytime the skin is rubbed against a hard surface, such as the ground, a sidewalk, a carpet, an artificial playing surface, or a road . School-age children ages 5 to 9 are most affected.
Scrapes can occur on any part of the body but usually affect bony areas, such as the hands, forearms, elbows, knees, or shins. Scrapes on the head or face may appear worse than they are and bleed a lot because of the good blood supply to this area. Controlling the bleeding will allow you to determine the seriousness of the injury. Scrapes are usually more painful than cuts because scrapes tear a larger area of skin and expose more nerve endings.
How a scrape heals depends on the depth, size, and location of the scrape. Occasionally the injury that caused the scrape will also have caused a cut or several cuts that may need to be treated by a doctor. For more information, see the topic Cuts.

Watch For Signs Of Infection
Most skinned knees heal within one to two weeks. However, if you notice any signs of infection, contact your family medicine practitioner.
HealthyChildren.org recommends seeking medical attention if the wound site swells, becomes red or hot, develops discharge or has a foul odor.
If your child develops a fever, this may also indicate the presence of infection.
What Are The Types Of Rfa Procedures
There are two main types of nerve ablation procedures, also called RFA, which stands for radiofrequency ablation. The first is called cooled RF, but it has nothing to do with icing the nerve.
In fact, electricity passes through the RF probe and this produces quite a bit of heat. The probe has to be cooled to maintain a constant and safe, but high temperature, which in turn cooks or destroys the nerve. In the second type of RFA, a pulsed electrical field is generated, which doesnt completely destroy the nerve .
PRF is generally considered safer in that there is less tissue damage, in addition, when cooled RF has been compared to pulsed RF, there was no difference in how the procedure worked across a review of many small studies . However, one of the reasons it doesnt get used as often is the more destructive type of RFA is eligible for insurance reimbursement.

What Are The Side Effects Of Radiofrequency Ablation
The most common side effect is numbness, tingling, or burning over the skin of the knee, which is due to the destruction of the nerve. Other side effects include infection, damage to the overlying tendons, and skin burns .
However, while rare, damage to the blood vessels can occur as well. The nerve travels with the artery and vein, hence when you ablate the nerve, you can damage either of those blood vessels. These adverse vascular events are documented in the literature with 27 cases being reported to date. Most often, there was a blow out of the artery , an abnormal connection between the artery and vein , bleeding into the joint , and/or death of the knee cap bone .

Skin Abrasions Were A Normal Part Of My Childhood
Spending most of my childhood in Midland, TX, and playing soccer, basketball and football, I had my fair share of skin injuries in sports. The main reason is because Midland is in the desert where the fields are basically dead grass sprinkled on top of hard dirt. Sliding on this surface will tear your skin up! Thats why I used to love traveling for tournaments to Denver, Dallas, & Austin because they have nice green, healthy grass fields. I remember getting excited as we got close to these cites because looking out the window of the car I could see how green and nice the fields on the side of the highway were. LOL. You have to have been to Midland/Odessa to understand what I mean.
When To Get Medical Help
Call NHS 111 or visit your local walk-in centre, minor injuries unit or GP surgery if there’s a risk your wound could become infected, or you think it’s already infected.
A wound is at risk of infection if:
- it’s been contaminated with dirt, pus or other bodily fluids
- there was something in the wound before it was cleaned, such as gravel or a shard of glass
- it has a jagged edge
- it’s longer than 5cm
- it was caused by an animal or human bite
Signs a wound has become infected include:
- swelling, redness and increasing pain in the affected area
- pus forming in or around the wound
- feeling generally unwell
- a high temperature of 38C or above
- swollen glands under your chin or in your neck, armpits or groin
An infected wound can usually be successfully treated with a short course of antibiotics.

Deterrence And Patient Education
Abrasions occur due to a variety of causes, some are innocuous, and others are extremely grievous. Patients and relatives need to be educated on the medicolegal importance of these seemingly inconsequential injuries. Clinicians also need to be aware of the importance of documentation. Abrasions in sports can be reduced by using protective measures, paddings, and appropriate clothing, etc.
Simple abrasions resulting from falls can be treated with first aid, and the patient and their relatives should receive education on first aid procedures, including cleaning the wound, removal of foreign material, and dressing with a non-adhesive material.
Sportmed Soccer Tips: Abrasions And Scrapes
A hand to the face or a hard fall from a tackle are just some of the ways a soccer player could suffer from abrasions and scrapes.
For the most part, this type of injury is fairly minor. However, if mistreated, that knee or hand abrasion could easily become infected. The first thing to do is to clean the wound with a water or saline solution, removing dirt and debris. A gentle brushing may be required to remove all foreign materials. Applying ice will ease the pain and reduce inflammation. Irritation from clothing or equipment could occur, so the wound must be protected by using a sterile non-adherent dressing such as a Telfa Pad.
Minor abrasions will form scabs and heal reasonably quickly, however, infection can occur . Serious infections could produce throbbing pain and swelling of lymph nodes. If thats the case, immediately seek medical attention.
In returning to play, be sure to protect the area of injury .

What Imaging Techniques Are Used To Place The Rfa Probe
Your doctor can use either fluoroscopy or ultrasound to guide the placement of the RF probe . Fluoroscopy allows him or her to see your bones, but not the nerve. Hence the probe is placed via bone landmarks in the locations where the nerve should likely travel.
Ultrasound does allow the doctor to see the nerve and place the needle across that area. However, in a recent study, despite this advantage, ultrasound-guided procedures didnt work any better than fluoroscopy-guided RFAs .

First Aid For Incised Wounds
Incised wounds are caused by sharp objects, such as knives or shards of glass, slicing into the skin. Depending on the injury, underlying blood vessels can be punctured, leading to significant blood loss. A severed artery is a medical emergency, because the muscular action of this blood vessel will pump the entire blood supply out of the wound in just a few minutes.First aid treatment for severe bleeding includes:
- Remove clothing around the site for easier access.
- Apply pressure directly to the wound with your hands to stem the blood flow.
- Cover the wound with a sterile dressing, if possible, and continue to apply direct pressure .
- Try to raise the injured area above the level of the persons heart.
- Dont remove existing dressings if they become saturated with blood, but instead add fresh dressings over the top.
- Seek urgent medical attention. You may need to call an ambulance if you cannot stop the bleeding, are feeling faint, sweaty or dizzy.

Abrasion Vs Cut Vs Laceration
So, you already know the basic abrasion definition: a skin scrape that may involve the epidermis or part or all of the dermis. A cut is a skin opening or incision caused by a sharp-edged tool or object. A laceration is a tearing of the skin that results in an irregular- or jagged-shaped wound. Sometimes the words cut and laceration are used interchangeably.
Lacerations are often more serious than abrasions because lacerations can extend very deep into subcutaneous tissues, including underlying muscle, internal organs or bone. Lacerations often require stitches. Symptoms of abrasions, cuts and lacerations include bleeding, pain and inflammation. Signs of an infected cut, abrasion or laceration are all similar and include increased pain, redness, swelling and/or foul odor.
