What should I do after surgery?

Anesthesia can sometimes cause nausea, so keep your diet light for the first 24 hours after surgery.

For 24 hours after surgery do not drive a car or operate hazardous equipment, sign important documents or make important decisions. Do not drink alcoholic beverages

Do resume your regular medications as directed by your physician.

It is normal to feel slightly dizzy and sleepy for several hours after your surgery. We recommend that you arrange to have someone with you during this time.

Rest on the day of surgery. This can be accomplished by the use a comfortable sleeping position. If you had a low back procedure you can sleep on your back with a pillow propped under your thighs and knees to maintain a natural bend at your back. Alternatively, you may rest on your side with a pillow between your thighs. If you had a procedure on your neck, make sure that if you lie on your back or side your neck is in a relatively neutral position. On your back you don’t want your pillow to be so big that your neck is hyper flexed. No pillow may cause your neck to be hyperextended. On your side, use a pillow sufficient to keep your neck straight without bending away or towards the bed.

Use the pain medication prescribed by your surgeon. Contact your surgeon if pain is unrelieved or increases. Remember, not filling your pain prescription or not taking it on time can lead to pain that is more difficult to treat.

Report any signs of infection. These signs may be fever, redness or swelling and discharge at the incision site, and feelings of malaise.

To avoid infection, take any antibiotics that your surgeon prescribed. The first dose is usually due the evening of surgery.

Report any excessive bleeding. Refrain from taking any blood thinners, aspirin or aspirin products for 24 hours unless dictated differently by your surgeon.

Avoid strenuous activity. Do not lift over 10 pounds. If you had back surgery, do not bend at the waist.

If a brace was given to you, use it when sitting, standing or upright, even if sitting upright in bed.

If a cold therapy unit was given to you, use it as directed.

If you have an incision, cover it with plastic prior to showering. Do not submerge it in a bath, Jacuzzi or swimming pool.

Call us immediately if problems arise, such as weakness, severe pain or any other changes.

Your surgeon will have additional instructions for you at your first post-operative visit.


What should I do prior to surgery?

Do not take food or anything to drink after midnight the evening prior to your procedure.

It is important to check with your internist, local doctor and cardiologist before surgery for approval regarding your medications that need to be discontinued before surgery, especially blood thinners.

You should take your medications for blood pressure, heart disease, asthma or emphysema. Take them with a small sip of water. If you are diabetic, do not take your oral diabetic medications. If you take insulin, contact us for special instructions. Please bring your medications with you the day of the procedure.

Avoid aspirin or other anti-inflammatory drugs, like Motrin, Ibuprophen, Celebrex or Naprosyn for at least 14 days prior to surgery. If you are taking blood thinners, like Coumadin, these should be stopped 3-5 days before surgery after arrangements are made with your doctor. Plavix should be stopped 7-10 days prior to surgery, but only after insuring the safety of stopping it with your prescribing doctor.

Leave your valuables at home. You must make arrangements to have a responsible adult drive take you home. Please have a telephone number for us to contact this person on the day of your procedure. You cannot proceed with your procedure if you do not arrange for a responsible adult to drive you home.

What are the risks associated with commonly performed spinal procedures?

All procedures carry some risk. Minor procedures are considered minor because there is a substantially reduced recovery period, or no recovery required, and the risks are very low. As always, Dr. Rappard will insure that the benefits of a potential operation far outweigh the risks.

Spinal injections

Spinal injections are considered minor procedures. Theoretical risks associated with spinal injection are nerve injury and infection. In 2013 there were reports of infections occurring with spinal epidural injections performed in other parts of the country. In these cases physicians were injecting medications that had been contaminated. Contamination occurred during the mixing of these medications at outside pharmacies. We do not use premixed medications. Our patients have never been at risk of infection from this form of contamination.

Cervical rhizotomy

A rhizotomy procedure is a procedure where a needle is placed against a nerve in the neck. Energy is then applied to the nerve resulting in a prolonged anesthesia. In about 10%–20% of cases patients will tell us that there is a transient spasm or a transient alteration in sensation of the skin. This usually resolves within 2–4 weeks.

Endoscopic spine surgery

Endoscopic surgery can have some important complications although the incidence is rare, about 2%. Complications include neurological injury. Neurological injury can result in numbness, pain and weakness. Other complications include bleeding or infection. If massive, complications could result in paralysis or loss of bowel and bladder function. It is important to note that complications of this degree are extremely rare. Side effects of endoscopic surgery are more common. In about 20% of lumbar cases we see postoperative leg pain. In some cases this is due to healing of a previously compressed nerve and in other cases this is due to irritation during surgery. This pain usually resolves within 4–6 weeks and can be treated relatively easily with medications or injections. Very rarely, there may be minor weakness due to nerve irritation. This usually resolves within 1–2 weeks.

Minimally invasive lumbar fusion

Minimally invasive lumbar fusion can have similar complications as endoscopic spine surgery, about a 2% risk of neurological injury. In addition, there is about a 10% risk of nonunion. Nonunion occurs when there is incomplete bony healing of the bone placed to span the region of the removed disc.

How are your results with endoscopic spine surgery?

We believe that patients are the ones that are most qualified to tell us how they did after surgery. When you come to our office for a consultation you’ll see that we ask you to fill out several forms. These forms are used to determine your pain and the level of disability caused by your spinal condition. These forms are important to us because we use them to measure our results later on. So, in reality, it’s really the patients that are telling us how we did. Unlike many surgeons, we ask that you return to us often. We strive to see all of our surgical patients at least up to a year. Even after a year you’ll fill out the same forms so we can see how we did in the long run.

We strive to be transparent about our results. Consequently, we often will present our results in scientific medical meetings. Scientific medical meetings are a venue used by physicians to exchange ideas and information. Presentations are peer reviewed, meaning that they are evaluated for importance, relevance and accuracy prior to allowing the presentation.

In July 2015 our results 6 months to 12 months after surgery for herniated lumbar discs were accepted for presentation at the Spine Intervention Society scientific meeting. We reported a greater than 80% success rate in treating back pain and leg pain, comparable to that seen with larger surgeries. In July 2013 we presented our results treating back joint arthritis with endoscopic surgery at the annual meeting of the International Spine Intervention Society. We reported a 100% success rate in reducing disability and pain. In February 2014 we presented our results in treating low back pain due to disc herniation with newer forms of endoscopic surgery at the annual meeting of the American Society of Spine Radiology. We reported a success rate of 94%, based on self-reported patient questionnaires. We look forward to presenting our ongoing results in future scientific medical meetings and to publishing our results in respected medical journals.

What are Dr. Rappard’s qualifications for performing endoscopic spine surgery?

Dr. Rappard’s core specialty is neurointerventional surgery. This is a rare specialty numbering approximately 800 physicians throughout the United States. Neurointerventional surgeons are board certified and trained neuroradiologists, neurosurgeons and neurologists who undergo the same training in advanced minimally invasive neurological procedures. It takes about 8 years of training after medical school to qualify in neurointerventional surgery. Dr. Rappard is a neurointerventional surgeon who is an endoscopic spine surgery specialist. The majority of the surgical procedures Dr. Rappard performs are endoscopic spine surgeries.

Dr. Rappard completed an internship in general surgery, a residency in diagnostic radiology, fellowship in neuroradiology, fellowship in neurointerventional surgery and a fellowship in endoscopic spine surgery, making Rappard not only a rare breed as a spine trained neurointerventional surgeon but also a rarity among endoscopic spine surgeons in general. Because of his training and background, Dr. Rappard is uniquely qualified to perform a careful neurological evaluation, perform image guided spinal procedures, expertly interpret patient MRI’s and serve as a qualified and experienced endoscopic spine specialist.

How do I tell if my physician is qualified?

Is there a board certification in minimally invasive spine surgery or endoscopic spine surgery?

There is no official board certification in minimally invasive spine surgery. However, all doctors performing endoscopic spine surgery should be board certified. Traditionally, spine surgeons have training and board certification in neurological surgery or orthopedic surgery. These surgeons in many cases went on to obtain additional training in spine surgery techniques, usually as part of a formal year long fellowship. A fellowship is a term to define formal training beyond a basic residency. It’s important to note that while a spine surgery fellowship implies competency in spine surgery it does not imply competency or skill in all spinal techniques or in endoscopic spine surgery.

Over the last 15 years there have been tremendous advances in medicine. The utilization of new technology has allowed for the development of small precision instruments, small high resolution cameras and sophisticated x-rays. This has further fueled innovation by allowing physicians to create new and innovative means of solving surgical problems. As a result, physicians skilled in the use of image guided techniques have adopted these new procedures and have entered the field of minimally invasive spine surgery. These physicians usually come from the fields of interventional pain management or radiology and have corresponding board certification in those fields. These doctors may be focusing their practice on minimally invasive spine procedures and may not practice in the field of their board certification at all, much like how a board certified orthopedic surgeon who performs spine surgery may not perform any general orthopedic procedures. As these image guided procedures have evolved we are now seeing some traditionally trained spine surgeons enter this field as well.

Why should I choose endoscopic surgery?

There are many forms of spinal surgery available today. Many forms of surgery are referred to as minimally invasive, although there are various degrees of being minimally invasive. Our underlying philosophy, the fourth pillar in the effective treatment of spinal pain, dictates that when we perform surgery it must be the most minimally invasive form of surgery available that can provide an effective result.

Endoscopic surgery is able to be performed through a tiny incision, often less than 1 cm. Dr. Rappard's incisions are commonly the size of the fingernail on his pinky. Through this tiny incision a tube is placed which enters the treatment area of the spine. Conventional surgery relies on a long incision so that the surgeon may look through the incision and into the treatment area. In endoscopic surgery the surgeon attaches a camera to the tube allowing the tip of the camera to be at the treatment site. This is like the surgeon having his eyeball on the treatment site instead of having to look through a large incision. The visualization for the surgeon is often better than when using the naked eye, magnifying glasses or a microscope. This allows the surgery to be performed effectively.

Besides allowing an effective surgery, the lack of a large incision and the use of a small tube means that the collateral damage associated with most common forms of surgery does not occur. There is no unnecessary cutting of muscle, ligaments or removal of bone and joints. This results in an effective treatment with a very rapid recovery.

What is minimally invasive surgery?

Minimally invasive spine surgery is a term that generally is defined as the performance of spine surgery in such a way as to minimize tissue damage and maximize recovery potential. While most physicians would agree with that definition it’s the interpretation that has become very loose.

On a surgeon by surgeon basis minimally invasive surgery becomes very subjective. Often it’s interpreted as “what’s the least invasive means I know of to perform what I deem to be effective spine surgery.” As a result, surgeon A may define minimally invasive as a 20mm skin incision and shaving off of portions of bone to perform a discectomy as an outpatient procedure. Down the street surgeon B may define minimally invasive as the complete removal of the disc, removal of most of a spinal joint, placement of a graft and prosthesis and placement of screws and rods through 2-20mm incisions performed as a procedure requiring an overnight hospital stay. What makes this all so subjective is that both surgeons may be offering this widely varied treatment to the same patient.

With such variations in the practice of minimally invasive spine surgery it’s more important than ever for patients to know what their options for effective treatment might be. Patients can rest assured that their surgeon is recommending the least invasive means of treating their problem that that surgeon feels competent with. However, that doesn’t mean that patients are being offered the least minimally invasive alternative. Therefore, it’s important to ask about damage to collateral tissues and the effects of that damage on recovery and rehabilitation. Also, ask if important ligaments and joints are going to be partially removed. Feel free to make comparisons by seeking a second opinion. Be leery though of surgeons that criticize each other’s approach. A good surgeon will know that there is more than one way to do minimally invasive surgery.

What is our treatment philosophy?

Dr. Rappard coined the phrase "the four pillars for the treatment of chronic spinal pain." Early in our practice we became interested in developing an underlying practice philosophy that would lead to our patients receiving more efficient and effective care. In addition, we wanted to develop a philosophy of care that would avoid most of the pitfalls commonly associated with spinal care and would minimize unnecessary treatment failures. The key is that we listen to our patients so that we can prescribe the right treatments to begin with, thus maximizing a patient’s chance to succeed. We also utilize an escalating care model. We make sure you have been maximally treated at one step before progressing to another step in your treatment.
