Because the battery-powered ME1000 automates THA, there is also likely to be less surgeon fatigue and potentially less work-related injuries that can arise from mallet use. A 2016 study published in The Journal of Arthroplasty showed that 66.1 percent of 183 orthopedic surgeons who responded to a survey experienced a work-related injury and that 31% of responding surgeons required surgery for their injury.1 The paper cited the use of repetitive movements with operating instruments and tools as a potential cause for upper limb tendinitis and discussed the need for measures to improve the surgical environment and work ergonomics for orthopedic surgeons.1
"In addition to its potential benefits for both patients and orthopedic surgeons, the ME1000 can be easily integrated into a surgeon's operational technique and into the hospital's processes," said Aaron Villaruz, global hip platform leader, DePuy Synthes Joint Reconstruction. "We at DePuy Synthes view this technology as a significant advancement as we strive to help our customers meet their goals of improving clinical outcomes, increasing patient satisfaction and managing costs."
The ME1000 is compatible only with DePuy Synthes hip systems. Adapters are available for anterior and posterior approaches to THA. One of the early users of the technology is Dr. Joel Matta, a pioneer in the Anterior Approach to Hip Replacement who is affiliated with the Steadman Clinic in Vail, CO.
"I've used the ME1000 on more than 100 primary DePuy Synthes hip implants, and my observation is that, compared to a mallet, the ME1000 reduces peak forces while increasing energy per second," said Dr. Matta. "I have found that the rotational stability of the implants is more easily and consistently achieved, and the risk of fracture potentially reduced. It is also easier for me to make adjustments, and achieve a precise position of the acetabular cup. I also appreciate that the physical effort and resultant fatigue from performing a hip replacement surgery is markedly reduced which benefits my capabilities during a full surgical schedule."
DePuy Synthes is expected to begin co-marketing the ME1000 with Medical Enterprises Distribution, LLC within the current quarter.
