Jack Elliot Zigler (born May 27, 1952 in Brooklyn, New York) is a Board Certified orthopedic surgeon specializing in spine surgery at the Texas Back Institute in Plano, Texas. He is best known for being the first surgeon to perform a ProDisc artificial disc replacement surgery in the United States, on October 3, 2001.
Since joining the Texas Back Institute in 1996, Zigler has been an international guest lecturer on topics in spinal reconstruction, as well as a Principal Investigator for the ProDisc artificial disc replacement system's U.S. Food and Drug Administration (FDA) clinical studies. He is a former Clinical Associate Professor of Orthopaedic Surgery at University of Texas Southwestern Medical Center in Dallas, Texas. He served as President of the American Spinal Injury Association from 2003 to 2005. [1]
Zigler's role as Principal Investigator for the ProDisc, Synthes Spine's artificial disc replacement system, was to monitor all the clinical ProDisc cases done at the Texas Back Institute, and also to serve as a resource to Synthes on questions about cases done at all of the 19 other investigative sites.
On August 14, 2006, the ProDisc-L ("lumbar") Total Disc Replacement was approved by the FDA for use as a treatment for functionally disabling pain from lumbar degenerative disc disease ("DDD"). It was the second device to be approved by the FDA for such a purpose.
As a condition of approval, Synthes Spine is required to conduct a five-year study assessing the long-term safety and effectiveness of the disc. The study will include the 286 patients who participated in the pre-approval clinical trials. The company is also required to complete an annual analysis and report any major adverse events (such as implant breakage, subsidence or expulsion from the disc space). These conditions are similar to those imposed on the Charite artificial disc. Zigler is himself responsible for publication of the national data now that the ProDisc-L has been FDA-approved.
More recently, questions about ethics of surgeon investigators in the Pro Disc study have been raised, specifically in a New York Times article about conflicts of interest related to his Zigler's financial ties, in which it is reported that he invested $25,000 in the company. [2] [3]
Since the time of these articles, there has been no substantiation to support the New York Times' allegations, and a follow-up FDA audit of Zigler's ProDisc site prompted by these allegations turned up no evidence of any wrongdoing.[ citation needed ]
Zigler has appeared as a guest expert on Orange County News network in Orange County, California, as well as Good Morning Texas, a morning show produced by the ABC affiliate WFAA-TV in Dallas, Texas. He has been consulted numerous times regarding the spinal injuries of such high-profile celebrities as Christopher Reeve and Jason Priestley.
Zigler is a contributing editor to Spine Trauma [9] and Spinal Arthroplasty, [10] authoritative medical textbooks. He has authored over 45 articles and chapters in internationally-read peer-reviewed medical journals and books.
"Spine Trauma" (1998) and "Spinal Arthroplasty" (2005). [11]
Orthopedic surgery or orthopedics is the branch of surgery concerned with conditions involving the musculoskeletal system. Orthopedic surgeons use both surgical and nonsurgical means to treat musculoskeletal trauma, spine diseases, sports injuries, degenerative diseases, infections, tumors, and congenital disorders.
Degenerative disc disease (DDD) is a medical condition typically brought on by the normal aging process in which there are anatomic changes and possibly a loss of function of one or more intervertebral discs of the spine. DDD can take place with or without symptoms, but is typically identified once symptoms arise. The root cause is thought to be loss of soluble proteins within the fluid contained in the disc with resultant reduction of the oncotic pressure, which in turn causes loss of fluid volume. Normal downward forces cause the affected disc to lose height, and the distance between vertebrae is reduced. The anulus fibrosus, the tough outer layers of a disc, also weakens. This loss of height causes laxity of the longitudinal ligaments, which may allow anterior, posterior, or lateral shifting of the vertebral bodies, causing facet joint malalignment and arthritis; scoliosis; cervical hyperlordosis; thoracic hyperkyphosis; lumbar hyperlordosis; narrowing of the space available for the spinal tract within the vertebra ; or narrowing of the space through which a spinal nerve exits with resultant inflammation and impingement of a spinal nerve, causing a radiculopathy.
Spinal fusion, also called spondylodesis or spondylosyndesis, is a surgery performed by orthopaedic surgeons or neurosurgeons that joins two or more vertebrae. This procedure can be performed at any level in the spine and prevents any movement between the fused vertebrae. There are many types of spinal fusion and each technique involves using bone grafting—either from the patient (autograft), donor (allograft), or artificial bone substitutes—to help the bones heal together. Additional hardware is often used to hold the bones in place while the graft fuses the two vertebrae together. The placement of hardware can be guided by fluoroscopy, navigation systems, or robotics.
Failed back syndrome or post-laminectomy syndrome is a condition characterized by chronic pain following back surgeries. Many factors can contribute to the onset or development of FBS, including residual or recurrent spinal disc herniation, persistent post-operative pressure on a spinal nerve, altered joint mobility, joint hypermobility with instability, scar tissue (fibrosis), depression, anxiety, sleeplessness, spinal muscular deconditioning and even Cutibacterium acnes infection. An individual may be predisposed to the development of FBS due to systemic disorders such as diabetes, autoimmune disease and peripheral blood vessels (vascular) disease.
The AO Foundation is a nonprofit organization dedicated to improving the care of patients with musculoskeletal injuries or pathologies and their sequelae through research, development, and education of surgeons and operating room personnel. The AO Foundation is credited with revolutionizing operative fracture treatment and pioneering the development of bone implants and instruments.
Manipulation under anesthesia (MUA) or fibrosis release procedures is a multidisciplinary, chronic pain-related manual therapy modality which is used for the purpose of improving articular and soft tissue movement. This is accomplished by way of a combination of controlled joint mobilization/manipulation and myofascial release techniques. MUA is used by osteopathic/orthopedic physicians, chiropractors and specially trained physicians. It aims to break up adhesions on or around spinal joints or extremity joints to which a restricted range of motion can be painful and limit function. Failed attempts at other standard conservative treatment methods, over a sufficient time-frame, is one of the principal patient qualifiers.
An artificial facet replacement is a joint prosthesis intended to replace the natural facets and other posterior elements of the spine, restoring normal motion while providing stabilization of spinal segments. It is typically used as an adjunct to laminectomy, laminotomy, neural decompression, and facetectomy, in lieu of standard lumbar fusion. The prosthesis is indicated for back and leg pain caused by central or lateral spinal stenosis, degenerative disease of the facets with instability, and grade 1 degenerative spondylolisthesis with objective evidence of neurological impairment.
Artificial disc replacement (ADR), or total disc replacement (TDR), is a type of arthroplasty. It is a surgical procedure in which degenerated intervertebral discs in the spinal column are replaced with artificial disc implants in the lumbar (lower) or cervical (upper) spine. The procedure is used to treat chronic, severe low back pain and cervical pain resulting from degenerative disc disease. Disc replacement is also an alternative intervention for symptomatic disc herniation with associated arm and hand, or leg symptoms.

Minimally invasive spine surgery, also known as MISS, has no specific meaning or definition. It implies a lack of severe surgical invasion. The older style of open-spine surgery for a relatively small disc problem used to require a 5-6 inch incision and a month in the hospital. MISS techniques utilize more modern technology, advanced imaging techniques and special medical equipment to reduce tissue trauma, bleeding, radiation exposure, infection risk, and decreased hospital stays by minimizing the size of the incision. Modern endoscopic procedures can be done through a 2 to 5 mm skin opening. By contrast, procedures done with a microscope require skin openings of approximately one inch, or more.
