PORTSMOUTH — A doctor at Portsmouth Regional Hospital says it has a new tool that will help patients who have shoulder surgery.

Dr. Moby Parsons helped to develop the ExactechGPS Guided Personalized Surgery advanced platform, which allows surgeons to combine preoperative planning with intraoperative computer-assisted technology. Doctors can create a 3-D anatomical model of their patient’s shoulder that can be put into planning software, allowing for a more accurate implant placement, Parsons said.

Parsons explained on Wednesday that as a shoulder is affected by arthritis, the socket changes. Traditional methods of preparing for surgery were difficult because they were based on a two-dimensional image of the shoulder socket.

“It was very hard to see the depth dimension. Now, you can really see what’s going on behind the face of it,” Parsons said.

Parsons worked with a development team of five other surgeons in the United States and a medical expert in Paris to help Exactech bring the concept to market. The process took eight years, he said.

Parsons was able to use the ExactechGPS for the first time at Portsmouth Regional Hospital Oct. 31.

“It’s pretty exciting to get it in the operating room,” Parsons said.

Parsons has been in practice for 14 years, and at 48 years old has had a shoulder replacement himself. He said they average 75 shoulder replacement surgeries a year at Portsmouth Regional Hospital.

The typical patient is between 65- and 75-years-old. The average shoulder replacement lasts five to 15 years. Parsons hopes the new technology will lengthen the replacement’s life expectancy.

“If we put the implants in better, they will last longer,” Parsons said.

Exactech, based in Gainesville, Fla, develops and produces bone and joint restoration products that help surgeons in more than 35 countries, according to its website.
