Elbow Injections (PRP, Cortisone, Stem Cell)
Elbow injures can be treated by joint injections that relieve inflammation and encourage healing. Some of the common injections are listed below.
What is Platelet Rich Plasma Therapy?
Our blood consists of a liquid component known as plasma. It also consists of three main solid components which include red blood cells (RBCs), white blood cells (WBCs), and platelets. Platelets play an important role in forming blood clots. They also consist of special proteins, known as growth factors, which help with our body’s healing process. Platelet-rich plasma or PRP is a high concentration of platelets and plasma. A normal blood specimen contains only 6% platelets, while platelet-rich plasma contains 94% platelets and 5 to 10 times the concentration of growth factors found in normal blood, thus providing greater healing properties.
What are the Indications for PRP?
PRP is a relatively new treatment method for several orthopaedic conditions such as muscle, ligament, and tendon injuries, arthritis and fractures. PRP injections can help alleviate painful symptoms, promote faster healing and delay joint replacement surgeries.
How is Platelet Rich Plasma Therapy Performed?
Your doctor will first draw about 10 ccs of blood from the large vein in your elbow. The blood is then spun in a centrifuge machine for about 10 to 15 minutes to separate the platelets from the remaining blood components.
The injured part of your body is then anesthetized with a local anesthetic. The platelet-rich portion of your blood is then injected into the affected area. In some cases, your doctor may use ultrasound guidance for proper needle placement.
What is the Post-Procedural Care for PRP?
- It is normal to feel some discomfort at the injection site for a few days after your procedure.
- You will be prescribed pain medications as needed by your doctor.
- You may use cold compresses to alleviate your symptoms.
- You will be instructed to stop any anti-inflammatory medications.
- You may resume your normal activities but should avoid any strenuous activities such as heavy lifting or exercises.
What are the Risks and complications of PRP?
There are minimal risks associated with PRP injections. Some of the potential risks include
- Increased pain at the injection site
- Damage to adjacent nerves or tissues
- Formation of scar tissue
- Calcification at the injection site
What is a Cortisone Injection?
Cortisone is a corticosteroid released by the adrenal gland in response to stress and is a potent anti-inflammatory agent.
Indications for Cortisone Injections
Cortisone injections are recommended in injuries that cause pain and inflammation, and those that don’t require surgical treatment. One such condition is frozen shoulder.
Cortisone Injection Procedure
Artificial preparations containing cortisone are injected directly into the affected joint to relieve pain and reduce inflammation. The effects may last for several weeks and cortisone injections.
Risks and Complications of Cortisone Injections
Cortisone injections offer significant relief in pain and inflammation; however, is associated with certain adverse effects. The most common side effect is a “cortisone flare”, a condition where cortisone crystallizes and cause severe pain for a brief period that lasts for a day or two. Cortisone flare can be minimized by applying ice to the injected area. Other adverse effects include whitening of the skin and infection at the injection site, a transient elevation in blood sugar if you are diabetic.
What is Stem Cell Therapy?
Stem cell therapy is a form of regenerative medicine that utilizes the body’s natural healing mechanism to treat various conditions.
Stem cells are being used in regenerative medicine to renew and repair diseased or damaged tissues, and have shown promising results in treatments of various orthopedic, cardiovascular, neuromuscular and autoimmune conditions.
Stem cells are present in all of us, acting like a repair system for the body. However, with increased age sometimes, the necessary amounts of stem cells are not present at the injured area. The goal of stem cell therapy is to amplify the natural repair system of the patient’s body by increasing the numbers of stem cells at injury sites.
Types of Stem Cells
There are two major types of stem cells: embryonic stem cells and adult stem cells.
Embryonic stem cells (ESCs) are stem cells derived from human embryos. They are pluripotent, which means they have the ability to develop into almost any of the various cell types of the body.
As the embryo develops and forms a baby, stem cells are distributed throughout the body, where they reside in specific pockets of each tissue, such as the bone marrow and blood. As we age, these cells function to renew old and worn out tissues and cells. These are called adult stem cells or somatic stem cells. Like embryonic stem cells, adult stem cells can also turn into more than one cell type, but their differentiation is restricted to a limited number of cell types.
Use of Stem Cells in Orthopedics
The unique self-regeneration and differentiating ability of embryonic stem cells can be used in regenerative medicine. These stem cells can be derived from eggs collected during IVF procedures with informed consent from the patient. However, many questions have been raised on the ethics of destroying a potential human life for the treatment of another.
Adult stem cells can be harvested from many areas in the body. These include adipose tissue (fat), bone marrow and peripheral blood. The mesenchymal stem cell is the most commonly harvested. These have the ability to turn into cells that form the musculoskeletal system such as tendons, ligaments, and articular cartilage. To obtain stem cells from the bone marrow, a needle is inserted into the iliac crest of the pelvic bone to extract the stem cells.
Currently, stem cell therapy is used to treat various degenerative conditions of the shoulder, knees, hips, and spine. Stem cells are also being used in the treatment of various soft tissue (muscle, ligaments and tendons) as well as bone-related injuries.
Who is a Good Candidate for a Stem Cell Therapy?
You may be a good candidate for stem cell therapy if you have been suffering from joint pain and want to improve your quality of life while avoiding complications related to invasive surgical procedures.
Preparing for Stem Cell Therapy
It is important that you stop taking any non-steroidal anti-inflammatory drugs (NSAIDs) at least two weeks before your procedure. Preparing for a stem cell procedure is relatively easy and your doctor will give you specific instructions depending on your condition.
Stem Cell Therapy Procedure
The procedure begins with your doctor extracting stem cells from your own bone marrow. Bone marrow is usually aspirated from your hip region. Your doctor will first clean and numb your hip area. A needle is then introduced into an area of your pelvic bone known as the iliac crest. Bone marrow is then aspirated using a special syringe and the sample obtained is sent to the laboratory. In the laboratory, the aspirate is spun in a machine for 10 to 15 minutes and a concentrated stem cell sample is separated.
Your doctor then cleans and numbs your affected area to be treated and then, under the guidance of special X-rays, injects the stem cells into the diseased region. The whole procedure usually takes less than one hour and you may return home on the same day of the procedure.
Postoperative Care for Stem Cell Therapy
You will most likely be able to return to work the next day following your procedure. You will need to take it easy and avoid any load bearing activities for at least two weeks following your procedure. You will need to refrain from taking non-steroidal, anti-inflammatory medications (NSAIDS) for a while as this can affect the healing process of your body.
Advantages of Stem Cell Therapy
Stem cell therapy is a relatively simple procedure that avoids the complications associated with invasive surgical procedures. As stem cell therapy uses the cells derived from your own body, it reduces the chances of an immune rejection.
Disadvantages of Stem Cell Therapy
There is a general lack of data about the long-term effects of stem cell therapy as it is a newer procedure and represents a newer form of treatment.
Risks and Complications of Stem Cell Therapy
Stem cell therapy is generally considered a safe procedure with minimal complications; however, as with any medical procedure, complications can occur.
Some risks factors related to stem cell therapy include infection as bacteria, viruses or other pathogens that can cause disease may be introduced during the preparation process.
The procedure to either remove or inject the cells also has the risk of introducing an infection to the damaged tissue into which they are injected. Rarely, an immune reaction may occur from injected stem cells.
