Patient: I’m 39 years old, male, I had surgery for isthmus cleft and lumbar 5 vertebral slippage in October 2003, and only 2/3 of it has been reset, and the surgeon said I can’t pull it. The titanium nail is fixed and has not been taken, some doctors are afraid of rebound, the surgeon said the bone graft grew well, I heard that once the bone graft grows well is very strong, right? I would like to ask the doctor a few questions, 1, is it possible not to take the domestic titanium nail, how can I test the implant really grow well I also feel relieved. 2, is it possible to have a sex life. 3, is it possible to participate in breaststroke? 4.What should I pay attention to in my daily life? I am a soldier, can I participate in the normal work training and exercises of the army in such a physical condition? Or should I rest at home? Thank you. Please be sure to take a look at my x-rays. The spinal surgery department of the People’s Hospital of Jimo City, Ren Shou Song: Hello, the answer is as follows: 1, whether the bone graft is fused according to the presence of lower back pain and reference to ordinary X-ray examination that can be judged. This judgment has to be made by the surgeon, because others do not know the specific way of bone grafting in surgery. Once it is determined that the bone graft has been fused, the internal fixation can be removed at an optional time. You are still recommended to take this out. 2, you can have a sex life 3, swimming is not a problem, the impact on the lumbar spine is not very big. 4, low back pain is not serious then you can resume normal work, whether you can participate in high-intensity training and training exercises, etc., to consider the views of the surgeon and the military doctors.
