New surgical option for wrist arthritis

17.02.2009
Innovative approach reduces pain, improves hand function

Breaking a fall, such as a tumble on the sidewalk, with your hands and wrists is everyone's natural reflex. But, if you fall hard enough, you'll often fracture your radius bone, or even one of the smaller wrist bones and wrist ligaments. Left untreated, these injuries could lead to disabling wrist arthritis.

For patients who develop wrist arthritis, a new surgical option known as OCRPRC (OsteoChondral Resurfacing in Proximal Row Carpectomy) is available at NewYork-Presbyterian Hospital/Columbia University Medical Center, where it is offered by one of the orthopedic surgeons who originally developed and described the technique -- Dr. Peter Tang. His research shows that the procedure reduces pain and improves hand function.

"I often see patients who had a wrist injury in the past who either did not seek medical attention or whose original injury was not diagnosed. As with most things in medicine, the earlier a diagnosis is made, the better the outcome. So if you continue to have pain after a month, you should make an appointment to see a hand surgeon for an evaluation," says Dr. Tang, who is an orthopedic hand surgeon at NewYork-Presbyterian Hospital/Columbia University Medical Center and assistant professor of orthopedic surgery at Columbia University College of Physicians and Surgeons.

Because the biomechanics of the wrist is both delicate and complex, an alteration in the normal anatomy can lead to arthritis. Once disabling arthritis develops, surgery cannot simply fix the injured structure, but rather must remove the arthritis and improve wrist function. The two most common operations for wrist arthritis are a partial fusion of the small wrist bones (intercarpal fusion) and excision of the first row of carpal bones (proximal row carpectomy, or PRC). There are various reasons to choose one operation over the other, but PRC has a quicker recovery, may be better for older patients, gives equal grip strength to intercarpal fusion, and usually results in more wrist motion.

Once the three carpal bones are removed during the PRC procedure, the capitate bone becomes the point where the wrist articulates with the arm; as such, it is important that the arthritis has not progressed to the capitate bone.

For these patients whose arthritis has progressed, Dr. Tang has adapted a cartilage-grafting technique that is used effectively in sports medicine treatments for cartilage disorders in the knee, ankle and elbow. The results are promising, according to his study in the Journal of Hand Surgery, with improvement in grip strength and decrease in pain levels.

"The goal of this new procedure is to give the best possible outcome by improving the cartilage status of the capitate bone. Another plus is that we do not have to take the graft from another part of the body. Even though we take out the three carpal bones for arthritis, there is usually one area of the bones where we can find undamaged cartilage for grafting," says Dr. Tang.

The study followed eight patients who underwent osteochondral resurfacing over 18 months. Preoperatively, seven patients described their pain as moderate to severe, while postoperatively, seven patients described their pain as mild to no pain, and one patient described the pain as moderate. Preoperative grip strength increased from 62 percent of their healthy side to postoperatively, 71 percent. Preoperative Mayo wrist score improved from a score of 51, which rates as "poor," to a postoperative score of 68, which rates as "fair."

The Journal of Hand Surgery study is co-authored by Dr. Joseph E. Imbriglia who is clinical professor of orthopaedic surgery and director of the Hand and Upper Extremity Fellowship Program at the University of Pittsburgh School of Medicine, where Dr. Tang did his training. Interestingly, Dr. Imbriglia did both his orthopaedic residency and hand fellowship training at Columbia University College of Physicians and Surgeons.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
