Hip Arthroscopy

Evaluaon of Hip Pain: Athletes & Pre-arthri&c Hips John P Salvo, MD Sports Medicine Rothman Ins&tute Clinical Associate Professor, Orthopaedic Surgery Thomas Jefferson University Hospital Philadelphia, PA Hip Injuries Hip injuries on the rise around MLB A-Rod, Utley among stars to deal with surgery, recovery Todd Zolecki MLB.com 6/4/09 PHILADELPHIA -- Mike Lowell followed the Marlins' strength and condi&oning programs religiously.He worked out properly.He stretched properly.But late in the season he felt &ghtness in his right groin. Nobody could figure out why exactly because he had completed every program asked of him. But regardless of how hard he worked, the groin always &ghtened.Lowell, who played for the Marlins from 1999-2005 before he joined the Red Sox in 2006, learned later he had a torn labrum in his hip and required surgery.He is not alone. Hip injuries have been diagnosed more frequently in Major League Baseball. Lowell, who had successful surgery to repair the labrum Oct. 20, 2008, is one of several notable players who have had hip surgeries in recent months. Others include Yankees third baseman Alex Rodriguez, Phillies second baseman Chase Utley, Mets first baseman Carlos Delgado and Royals third baseman Alex Gordon. Phillies pitcher Breb Myers had successful hip surgery Thursday."You know, Tommy John got a surgery named aer him. I think they should name this one aer me," Lowell joked.But why all the hip injuries all of a sudden?"I think the main reason is improved recogni&on of the pathology," said orthopedic surgeon and hip specialist Bryan T. Kelly, who peformed Myers' surgery at the Hospital for Special Surgery in New York. "They were treated with rest and an&- inflammatories, and they would get persistent problems with it. Now we're beginning to recognize that a lot of problems that seem to be muscle strains or muscle pulls are ending up these [hip] problems.""Are these injuries occurring more frequently or are we just more aware of them and more precise at diagnosing them and treang them?" said Phillies team physician Michael Cicco, who is in&mately familiar with hip injuries because of Utley and Myers. "It could be a combinaon of both of those. To answer that ques&on, you really need to have an understanding of the injury."
