A short history of my recent tennis injury and questions about diagnosis with a WARNING at the end. December 29th, 2009, 9:30 PM -- While playing in a tennis tournament heard a snap and fell down with a pain just below the bulge of the right calf muscle (gastroc). Could not put any pressure on the ball of the right foot due to pain in the calf. Was helped off the court and to my car and drove to the ER. December 29th, 2009, 10:30 PM -- ER examination by MD and she was not sure if injury was to the Achilles or gastroc. Lateral and AP X-rays were taken of right lower leg. Reading by radiologist indicated, “ … xrays were normal.” I felt the Achilles tendon and there was some tendon there, but it felt thin to me. December 30th, 2009 4 PM – saw orthopedic surgeon and he thought there was a partial tear of the Achilles tendon, ordered an MRI of the lower leg. He was surprised at the force I could exert when pointing my toes. I had complete ranged of motion in my right foot without pain in the tendon, but minor pain in the lower gastroc. December 31st, 2009 1:30 AM got MRI December 31st, 2009 noon radiology report arrived. “There is a full-thickness transection of the Achilles tendon 4-5 cm from distal attachment.” When I palpated the tendon in the ER there was no pain associated with the tendon. Pain was in the lower gastroc. As mentioned above there was something there, which I though was tendon in the area of the supposed transection and without a depression or bulge often associated with a complete rupture. Also, although xrays are not good at showing soft tissues, I have seen the outline of the Achilles on a radiograph I had of my left lower leg and am wondering how a full-thickness transection of the Achilles tendon with 3 cm between the ends could be missed when that is the question everyone is and should be asking. The radiologist who read the MRI didn’t see the xrays or details of the physical exam. In talking with a physician who had tendon surgery, he mentioned that he had two radiologists read the MRI and one came up with complete rupture and the other said no rupture. At surgery there was 50% of the tendon left. Will get a second opinion and second reading of the xrays and MRI and keep you posted. What is possibly frustrating and you can add you own words is I feel fine with minimal pain mainly in the lower gastroc area and I can walk in small steps without any pain. If I do need surgery, I wish I felt worse and not better everyday. ********* WARNING ********** I got back from the Far East on December 20th, and was taking a five day course of Cipro for diarrhea and stopped on December 21st. Cipro and antibiotics of that class ARE associated with tendon rupture. I didn’t know that when I took it.
