Dr. McConnell First in Lehigh Valley to Perform Spine Surgery Using activL® Artificial Disc

New Procedure Gives Young, Active Lehigh Valley Patient with Degenerative Disc Disease Hope for an End to Chronic Pain.

Dr. Jeffrey McConnell is the first spine surgeon in the Lehigh Valley to successfully implant an innovative artificial spinal disc replacement device to address chronic low back pain caused by degenerative disc disease. The  activL® Artificial Disc from Aesculap Implant Systems is designed to closely mirror the natural movement of a healthy human spine, preserving more motion in the spine than traditional fusion surgery.

With traditional fusion surgery, some patients with degenerative disc disease have reported pain at levels adjacent to their initial fusion several years after surgery. In clinical studies, patients who received a lumbar artificial disc were three times less likely to experience pain at adjacent levels 5 years after their procedure than patients who received a fusion.

“I have been an early adopter of motion-preserving procedures because I have seen the value in both my own patients as well as in the academic literature,” said Dr. McConnell. “I believe that the activL Artificial Disc represents the next generation of spinal disc replacement technology, especially for younger, more active patients.”

McConnell performed the first surgery using activL Artificial Disc at St. Luke’s Allentown campus in May. “Two weeks following my patient’s initial surgery she is already reporting a significant reduction in the pain she experienced before the procedure, and she is up and walking around,” said McConnell. “I am confident as she continues to heal that she will greatly benefit from receiving this artificial disc.”

Aesculap’s activL Artificial Disc was approved by the FDA in June 2015, making it the first new lumbar disc on the market in nine years.

Two Level Cervical Artificial Disc Replacement Superior To Fusion

 

eurospine conference

During the recent Eurospine meeting in Berlin, Germany,  a paper co-authored by Dr Jeffrey McConnell was presented, which explored the results of one of the longest follow-up studies on cervical total disc replacement to date.

Long Term Clinical and Radiographic Results of Two-level Cervical Total Disc Replacement from a Level 1 Prospective, Randomized, Clinical Trial”, compared patients who received fusion surgery vs patients who received artificial disc replacement surgery. The highlights:

  • After 7 years, patients who received the Prestige-LP two level artificial disc replacement had superior overall clinical results when compared to the fusion patients.
  • Subsequent surgeries were required 3 times less often in patients who received the two-level artificial disc replacement.
  • Patients who had cervical fusion required surgery at adjacent disc levels twice as often as the patients who had disc replacement.

These long term clinical results demonstrate the effectiveness of total disc replacement at 2 contiguous levels in the cervical spine and the importance of maintaining motion in the cervical spine.

 

The Prestige-LP two level artificial disc replacement.

Cervical artificial disc replacement is a type of joint replacement procedure. An artificial disc, such as the Prestige LPTM cervical disc made by Medtronic, is placed between two adjacent cervical vertebrae to replace a diseased cervical disc. It is designed to maintain the distance between two adjacent cervical vertebrae.

Cervical total disc replacement has been demonstrated to be a very effective alternative to the traditional surgery of fusion for painful herniated discs in the neck.  Total disc replacement in the neck is more successful because it maintains normal motion in the neck while fusion eliminates motion.  This preservation of motion is key to minimizing the degeneration of adjacent cervical discs.

Can Artificial Total Disc Replacement in the Neck Prevent Problems at Adjacent Discs?

While fusion surgery is generally successful for treating herniated discs in the neck it comes at the expense of lost motion between two vertebra.  Lack of movement  at one disc will increase stress and strain at the adjacent discs.  The disc adjacent to a fusion can degenerate faster and may become painful and require additional surgical intervention.

Dr McConnell recently reported the long term beneficial effects of total disc replacement in the neck at the North American Spine Society Meeting in Boston.  The presentation was entitled:  Motion Preservation at the Operative Level and the Incidence of Symptomatic Adjacent Segment Disease after Treatment with Secure-C or ACDF.  This study followed 380 patients with herniated discs treated with either total disc replacement (Secure-C artificial disc) or fusion to see what happened to the adjacent discs after 7-years.  Of the patients  who had fusion in their neck 17.4% had additional surgery at an adjacent disc while only 4.2% of the patients treated with Secure-C had adjacent disc surgery.  After 7 years, patients treated with fusion surgery in the neck for a herniated disc were 4 times more likely to require surgery at any adjacent disc level then patients treated with an artificial disc.   These results were significant and highlight the benefits of total disc replacement in helping to prevent accelerated degeneration of adjacent discs and the importance of maintaining normal motion in the neck.

The Scoliosis Research Society 23rd International Meeting on Advanced Spine Techniques

Friday, July 15, 2016 | Washington, DC, USA

At this leading and prestigious scientific meeting on spinal surgery, Dr. McConnell presented the 7-year results of the clinical study involving the Prestige-LP cervical disc arthroplasty device. The FDA investigational device exemption (IDE) clinical trial compared the Prestige-LP total disc device to replace two consecutive discs in the neck versus the traditional surgery of two level disc fusion. At 84 months follow-up, patients who received the Prestige-LP two level artificial disc replacement achieved superior overall clinical results when compared to the fusion patients. At 7-years patients who received the two-level artificial disc replacement required 3-times fewer subsequent surgeries at the treated disc levels.  Patients who had cervical fusion were twice as likely to require additional surgeries at adjacent disc levels.  These longer term clinical results continue to demonstrate the efficacy of total disc replacement at 2 contiguous levels in the cervical spine.

Case Study: Degenerative Disc Conditions

Meet Bob – a Coopersburg resident and father of three. For most of his adult life, Bob suffered with chronic neck and back pain. As if his chronic pain wasn’t enough to alter his life, his condition was also associated with numbness and tingling in his left arm and hand, and sciatic pain down his left leg. After years of suffering, Bob looked to Dr. Jeffrey McConnell of OAA’s Spine Center of Excellence to IMG_0644perform surgery on his spine. “Finding Dr. McConnell was one of those life changing experiences I want anyone suffering from similar pain to hear about,” said Bob.

A previous surgical patient of Dr. Hawk, Bob was in his office for a checkup on his shoulder when Dr. Hawk suggested that he schedule an appointment with Dr. McConnell to address the pain in his neck and back. Knowing that he has complete trust in Dr. Hawk, Bob decided to listen to him and get Dr. McConnell’s opinion despite already having an operation scheduled with another surgeon.

Dr. McConnell looked at Bob’s MRI and EMG tests and saw him for an appointment several days later. After a thorough in-office exam, Dr. McConnell was not in agreement with Bob’s original diagnosis from another surgeon, and scheduled him for a CT scan to confirm his suspicions. “I was beginning to realize just how lucky I was in following through with Dr. Hawk’s suggestion,” Bob recalled. At another appointment to go over the findings of the CT scan, Dr. McConnell’s suspicions were confirmed, and he explained to Bob what the CT scan, MRI, and his symptoms were telling him about Bob’s condition. “I knew I found the right doctor,” said Bob, “not only did he tell me what was causing my pain, he showed me.”

Dr. McConnell has been a spine surgeon for 24 years, and has subspecialty interests in scoliosis surgery, total disc arthroplasty in the cervical spine, and minimally invasive spine surgery. When asked about Bob’s condition, Dr. McConnell noted, “Pain from a pinched nerve is one of the worst kinds of pain a patient can experience. Once the nerve compression is relieved with surgery, patients will typically experience complete pain relief and a corresponding significant improvement in quality of life. Bob had not just one nerve being pinched, but three, therefore his pain and disability were even greater.”

Dr. McConnell and Bob weighed the pros and cons of various surgical approaches. “Dr. McConnell explained to me how each option would benefit or detract from the outcome he was seeking. This is how medicine should be practiced! He put my mind at ease and I knew he was prepared to handle whatever was needed to alleviate my years of pain and suffering,” said Bob.

When asked about the surgery, Dr. McConnell explained, “Bob’s condition was secondary to multilevel degenerative disc disease and bone spurs which were compressing several nerves to his left arm. To treat his condition, we had to perform anterior discectomy and interbody fusions at C4-5, C5-6, and C6-7.” In other words, Dr. McConnell removed the collapsed discs in Bob’s neck, which then allowed him to remove the bone spurs that were compressing the nerves to Bob’s arm. To further restore the opening between the vertebra and to provide additional space for the nerve roots, spacers were placed between the vertebra to hold them apart. Then, to lock the spacers in place and to bind the vertebra together, small plates were inserted into the vertebra. Patients like Bob are a constant reminder as to why Dr. McConnell became a spine surgeon – “I enjoy solving problems and having the opportunity to improve patients’ lives through surgery,” Dr. McConnell affirmed.

Reflecting back to the day of surgery, Bob said, “It is hard to put into words the times in one’s life that are mystical; like when you are there for the birth of a child, or when other miraculous things happen, but I can tell you waking up after surgery and immediately noticing feeling in your hand without any numbness or burning is one of those spiritual moments you will never forget. I will be forever grateful to Dr. McConnell, his staff, and Dr. Hawk for his suggestion to see Dr. McConnell. They should be proud of what they do and how they do it – we are all better off because of them!”
