SpineFrontier A Meeting of the Minds: Dr. Kingsley R. Chin Speaks among Dr. Bash & Dr. Aferzon

A Meeting of the Minds: Dr. Kingsley R. Chin, Dr. Bash & Dr. Aferzon

Dr. Jeffrey Bash and Dr. Joseph Aferzon recently hosted an event at the Capital Grille in Hartford, Conn. The dinner was a meeting of the minds and featured Dr. Chin, the surgeon-entrepreneur founder and CEO of SpineFrontier. In addition to the hosts, the event was attended by several prolific Connecticut surgeons brought together by a common interest in innovative product design and outpatient care.

The evening kicked off with a round table-style, open forum discussion about surgeon innovation at SpineFrontier. Dr. Bash and Dr. Aferzon spoke glowingly about their experiences working with SpineFrontier designers and engineers. They described the benefits of collaborating with SpineFrontier’s talented and smart product design team who have taken their ideas for new and better products and instruments and turned them into reality. Dr. Bash noted that the SpineFrontier team was unique in both its ability to understand surgeons’ input and direction and to design intelligent products and instruments that worked better for surgeons and patients.

The discussion turned to the rise of outpatient treatment out of necessity for patient safety. Dr. Chin and Sarah Cook (a SpineFrontier Mechanical Engineer) shared case studies with the group and talked about SpineFrontier’s variety of product offerings. The rest of the evening centered on a vibrant discussion about the spine industry, the rise of outpatient treatment, new billing restrictions and innovative surgical techniques

To wrap up the evening, Jake Lubinski, president of AxioMed, gave a short presentation on AxioMed’s clinical studies of its Freedom® total disc replacement technology. Frank Schnur, the Chief Sales Officer of KICVentures, spoke about the KICVentures’ ecosystem of health-tech companies and its entrepreneurial movement.

Dr. Kingsley R. Chin visits CSRS: A Follow Up

On Dec. 4 and 5, Dr. Chin attended CSRS (Cervical Spine Research Society) in San Diego. For the fuller story, read the Spark article: AxioMed Planning To Bring Its Cervical Viscoelastic Total Disc Replacement to the U.S. Dr. Chin reports here briefly on his experience.

“At CSRS, I met with key opinion leaders to discuss bringing the IDE for the AxioMed cervical TDR to the USA and to also discuss how to organize surgeons to participate in raising the capital to fund the IDE to bring the cervical TDR to market.  Surgeons shared that they are convinced that the viscoelastic TDR is the best available solution for treating disc disease in the cervical spine over either fusion or disc replacements with moving pieces that act as joint replacements. AxioMed’s Freedom Disc is a true replacement that mimics the natural disc to restore alignment and motion,” said Dr. Chin.

The disc is available outside the USA and is exclusively distributed by SpineFrontier.

Modern advances in spine surgery including less invasive procedures have propelled the design of instruments and implants to achieve greater posterior spinal fixation, with decreased tissue destruction and higher safety margins.  Static and dynamic biomechanical studies have validated the superior pullout strength of cortical screws versus the traditional pedicle screws and might represent an opportunity to perform safe lumbar fusions in ambulatory surgery centers (ASC).  The authors aim to compare the outcomes of midline cortical pedicle screw surgical technique for posterior lumbar fixation in the ASC compared to traditional pedicle screws in a hospital.


The medical records of 60 patients with prospectively collected data were reviewed. Two matched cohort groups consisting of 30 patients each, midline cortical pedicle screws performed in ASC patients (Group 1) was compared to traditional pedicle screws performed in Hospital patients (Group 2). Outcomes were measured using Visual Analog Scale (VAS) scores, Oswestry Disability Index (ODI) scores, estimated blood loss (EBL) and Radiologic fusion rate.


33 males and 27 females, age range (28-75), average 58±3 years. Average BMI was 29±1.15 kg/m2. Significant improvement noted in VAS back pain scores in Group 1 from 7.8±0.5 to 2.5±0.7, p=0.001. Comparing VAS back pain scores and ODI scores, significant improvement demonstrated between group 1 and 2, p=0.004 and p=0.027 respectively. Mean EBL in group 1 was significantly less, p=0.025 than group 2. Intergroup fusion rate at two year was similar, p=0.855.


We successfully transitioned our lumbar fusions from hospitals to ambulatory surgery centers using a midline cortical pedicle screw technique. Although traditional pedicle screw placement was effective and may be viable in an ambulatory surgery center we see more advantages to use midline cortical screws over traditional pedicle screws.

Dr. Kingsley R. Chin Delivers Lecture at Symposium on Minimally Invasive Spine Surgery

On Sept. 23, 2015, Dr. Kingsley R. Chin presented on “Ambulatory/Outpatient Minimally Invasive Surgery” at the University of Massachusetts Memorial Health Care’s Department of Neurological Surgery’s Symposium on Minimally Invasive Spine Surgery.

Dr. Chin spoke to an audience of physicians and medical students about the changing healthcare system. He provided a surgeon-entrepreneur’s perspective on trends in consumer-facing technology and outpatient technologies. He explained how these technologies have the potential to cause a disruption of the high-cost hospital model and enable movement toward a less expensive outpatient model that empowers both patients and surgeons.

“Dr. Chin has a purposeful way of speaking, and can connect with any audience.”

Susan MacNeil, coordinator of the Symposium, said that she received positive feedback after Dr. Chin’s lecture. “People were surprised to learn how much Dr. Chin had accomplished at a young age, and they found him to be an interesting speaker.

Peter Prinos, who also attended the symposium said that, “Dr. Chin has a purposeful way of speaking, and can connect with any audience.”

Jamaica’s First A-CIFT™ SoloFuse-P™ Case LESS Institute Gives Back - SpineFrontier

The LESS Institute Gives Back

On July 3, 2015, Dr. Kingsley R. Chin of the LESS Institute in Florida and Jamaican Neurosurgeon Dr. Franz Pencle performed a Less Exposure Surgery procedure on a middle age, male patient who suffered from severe myelopathy (spinal cord compression) due to a progressive degenerative disorder. The procedure took place at Cornwall Regional Hospital in Montego Bay, Jamaica. Before surgery, the patient was incapacitated. “He was basically quadriplegic,” Dr. Fabio Pencle, a LESS Institute Research Fellow who supported the case says. “On his strength test, he scored a 1/5 throughout all limbs –which means he could barely flicker his digits.” Dr. Fabio Pencle believes that the patient survived because of treatment. “Patients with similar symptoms demised because they didn’t receive timely treatment,” says Dr. Fabio Pencle.

Dr. Chin, Dr. Franz Pencle and Dr. Fabio Pencle donated their time for the case and SpineFrontier, Inc. donated the SoloFuse hardware. The Less Exposure Surgery (LES) procedure was performed through a midline cervical incision, dissection to expose the affected level and a discectomy using rongeurs and burr. A DBM packed A-CIFT SoloFuse was placed and fixed with screws. This was the first case of a standalone implant in Jamaica. It was also the first outpatient spine surgery done at Cornwall Hospital. The patient could sit upright twelve hours after surgery, and he tested 5/5 on a strength test in the upper limbs and 4/5 in the lower limbs –indicating that he had significant improvement in less than 24 hours.

LESS Talk, More Doing: Changing Lives in Jamaica, SpineFrontier Less Exposure Surgery story

LESS Talk, More Doing: Changing Lives in Jamaica

On a late Saturday night in May, an unlikely group of people’s paths crossed in a small operating room in the University Hospital of the West Indies. It was hot, and beads of sweat formed on the doctors’ foreheads above their surgical masks. Outside the O.R., the windows in the hallways were open to catch the breeze that filtered through the open slats. The hallway was quiet, filled only with an empty gurney with a canvas stretcher and wood handles. A clock on the wall covered in a metal casing methodically tracked the passing moments.

Inside the O.R., Dr. Kingsley R. Chin, an orthopaedic surgeon and founder of Less Exposure Surgery Specialists (LESS) Institute in Florida, and Dr. Carl A. Bruce, a consultant neurosurgeon at the University of the West Indies at Mona Jamaica, operated on a fifteen year old young woman. Around them stood Kevin Chappuis, a medical technology engineer from SpineFrontier, Inc, Harisha Buggam, a medical device distributor in the West Indies, and the University’s Chief of Anesthesiology, Dr. Harding. The operation, a high level, scoliosis case, required that surgeons correct a deformity in the patient’s spine.

Shinel Binns, the patient lying on the operating table, was fit and healthy -a normal young woman in every way, except for the severe curve in her spine. Standing up, Shinel’s legs were perpendicular to the ground, but at her waist, her torso and head angled sharply to the left, as if she had to fight gravity from pulling her left shoulder and head to the ground. A lifetime of trying to hold her head and torso upright to counterbalance her lumbar spine’s deformity had begun to create a curve in her thoracic spine.

Shinel lived in Saint Elizabeth Parish –a two hour journey from the hospital she was now being treated at in Kingston, Jamaica. She and her family had waited a long time for this moment. She would never have been able to afford an operation, but the donated time from the doctors, and over $500,000 in donated technology and personnel from SpineFrontier, as well as her community’s donation of $5,000, was making her operation possible.

Dr. Kingsley R. Chin had flown in earlier that day from the United States. Born and raised in Jamaica, he often returned to perform surgeries for people in need. As a pioneer in the Less Exposure Surgery (LES®) approach, Chin has devoted his life to refining and training others in a revolutionary approach to back surgery. The LES Philosophy of surgery pinpoints the problem, fixes it without collateral damage to surrounding tissues, and lets patients go home the same day.

A patient examination and X-Rays had confirmed to the doctors that Shinel’s original spinal deformity was in the lumbar spine. Because the thoracic curve was compensatory to keep her upright, Dr. Chin and Dr. Bruce operated on the most pronounced section of the curve (L1-L4). Dr. Chin used a Less Exposure Surgery (LES) approach, addressing the most pronounced section of the spinal curve (L1-L4) by inserting SpineFrontier’s S-LIFT® Lateral Interbody through a single, three inch incision at those levels to straighten out the spine. The surgeons then placed unilateral MISquito® Percutaneous Pedicle Screws to hold the straightened position.

The LES approach through the small incision on the side of the abdomen was low impact and saved Shinel the trauma of an incision through her stabilizing back muscles that could disrupt her strength. It also minimized the surgical trauma and maximized its effectiveness for a rapid and less painful recovery. This approach was especially important because it would allow a teenage girl to resume her daily activities more quickly. The surgeons expected that the thoracic curve would straighten itself over time. After the operation, Shinel already felt straighter and only had minimal superficial pain.

Harisha Buggum, the medical device distributor, had observed several other scoliosis corrections before through the Scotiabank Scoliosis Programme that provided implants at a greatly reduced cost to teenagers with scoliosis. But she had a renewed sense of excitement when talking about Shinel’s operation.

In this surgery, you could see the technology changing the deformity and you could see the spine literally straightening up through the fluoro imaging. It’s good to know technology has turned in the direction so that someone with scoliosis can actually get a correction from Less Exposure Surgery.”

“I’ve never seen that kind of procedure done,” Harisha said, leaning forward and talking energetically, “This was different for us than our day-to-day [procedures]. In this surgery, you could see the technology changing the deformity and you could see the spine literally straightening up through the fluoro imaging. It’s good to know technology has turned in the direction so that someone with scoliosis can actually get a correction from Less Exposure Surgery.”      

Harisha’s excitement over what she observed in the O.R. was just a small window into the many cases that Dr. Chin and his colleagues at the LESS Institute perform on a daily basis in the United States.

“This case is a perfect example of how Less Exposure Surgery can transform a patient’s life,” Chin commented.

Dr. Kingsley R. Chin Successfully Implants New E-LIFT

Dr. Kingsley R. Chin Successfully Implants SpineFrontier’s New E-LIFT Interbody Cage at University Hospital in Tamarac, Florida

Beverly, MA – February 29, 2012 ­– SpineFrontier, Inc., a medical device company focused on developing less exposure surgery (LES) technologies, announced today that Kingsley R. Chin, M.D., an Orthopedic Surgeon at the Institute for Modern and Innovative Surgery (iMIS) in South Florida, has successfully implanted the first E-LIFT interbody cage through an extraforaminal oblique-lateral approach at L4-5. The patient was a 77-year-old female with degenerative spondylolisthesis, severe neurogenic claudication, and back pain.

“The E-LIFT system allowed me to do this surgery through a one centimeter incision with only 30 cc of blood loss, and less than three minutes of live fluoroscopy time. We increased the disc height and foramen with a 12 millimeter E-LIFT PEEK cage, which treated the patient’s stenosis and instability,” said Dr. Chin. “We avoided having to use a lateral decubitus position, which would risk injury to the lumbar plexus had we used a direct lateral approach. Instead, we were able to add posterior LES technologies to decompress and stabilize the lumbar spine without changing the patient position. I think the E-LIFT technique has the potential to be the best approach for interbody fusion from L1-L5.”

Dr. Chin is a graduate of Harvard Medical School and trained at the Harvard Hospitals, including Massachusetts General Hospital in Boston. He is a board certified Orthopedic Spine Surgeon who completed a fellowship specializing in spinal surgery at Case Western Reserve University under the mentorship of Henry H. Bohlman, M.D.  Dr. Chin has published extensively, holds multiple patents, edited textbooks, lectured worldwide on spine surgery, and was an Assistant Professor of Orthopaedic Surgery and Chief of Spine Surgery at University of Pennsylvania Medical School from 2003 to 2007. He founded and currently runs the Institute for Modern and Innovative Spine Surgery in South Florida.

About LES Technology

E-LIFT Extraforaminal Lateral Interbody System is a Less Exposure Endoscopic Surgery (LEES) technology from SpineFrontier, Inc. that adheres to the LES philosophy for spinal fusion. E-LIFT is designed for the goal of spinal stabilization, while minimizing incision size, preserving the facets, and retaining the normal anatomy.

“The E-LIFT technique is based on the principle of distracting the disc space with sequential dilating cannulas to increase the foraminal height. This allows for a more complete discectomy and endplate preparation for fusion,” said Dr. Chin. “Standard lateral access instruments like shavers and curettes are used though the cannula. The bulleted and cannulated E-LIFT PEEK cage further self-distracts the disc space during insertion over a guidewire or through the LESR-O cannula.”

E-LIFT is a spinal intervertebral body fusion device intended for intervertebral body fusion of the spine of skeletally mature patients, using autogenous bone graft to facilitate fusion. The device is indicated for use in patients with degenerative disc disease (DDD) at one or two contiguous spinal levels from L2-S1. These DDD patients may also have up to Grade I spondylolisthesis or retrolisthesis at the involved level(s). The SpineFrontier E-LIFT Intervertebral Body Fusion Device is intended to be used with supplemental spinal fixation system(s) cleared for use in the lumbar spine (example: Facet Screw Fixation).

“The E-LIFT system provides surgeons the unique benefits of an effective discectomy and safe interbody delivery without impact to anatomy,” said SpineFrontier’s E-LIFT Product Manager Vito Lore.
