He held that position until March 1, 1999. His work from 1977 to 2006 not only included treating patients, he also served as acting director of pain services at TTUHSC, and oversaw the expansion of operations and future development of the Messer-Racz International Pain Center named in recognition of Racz's work and the Messer family's financial contributions. In 2015, Racz held the designation of Professor and Chairman Emeritus, Director of Pain Services for Texas Tech University Health Sciences Center. Throughout his career, Racz has also conducted research and co-authored articles with other experts in pain management to improve diagnosis and treatment of complex regional pain syndromes (CRPS), a long-term disorder of the nervous system which is a challenging pain problem that is often misunderstood and misdiagnosed. Racz's work with nerve stimulators, spinal cord stimulators, radiofrequency thermocoagulation, and a wide range of other pain management procedures is being used in interventional pain practices throughout the world. He developed new designs in medical equipment and devices. In 1982, Racz designed the Racz catheter, a flexible, spring-wound catheter with a small fluoroscopic probe. In 1989, he developed epidural lysis of adhesions, a minimally invasive, percutaneous procedure also known as the "Racz procedure", which is somewhat similar to an epidural. It is used to treat patients with chronic low back pain due to post lumbar surgery syndrome, sometimes called failed back surgery, which involves scar tissue that has formed around the nerve root. It is also used to treat protruding or herniated disks, fractures, degeneration, or radicular pain from spinal stenosis, a disease of aging. The Racz procedure employs a wire-bound or spring loaded catheter to mechanically break-up or dissolve scar tissue, also called epidural adhesions or fibroids, that have formed around the nerve roots, and allows for local anesthetics, saline, and steroids to be injected into the affected area. This procedure was assigned a Current Procedural Terminology (CPT) code in 2000. In 1996, Racz was the first recipient of the Grover E. Murray Professorship, TTUHSC's highest award. In December 1998, the University Medical Center named him to a $1 million endowed chair in recognition of his work at TTUHSC and the University Medical Center. In 2004, he received the Lifetime Achievement Award presented by the American Society of Interventional Pain Physicians.
