Hip defect leads to shorter leg prosthesis, the doctor 3D print custom fit bone defect patients. Yesterday, the hip replacement successful bear (a pseudonym) has been able to start walking, which marks the central region of the hip replacement surgery for the first time to achieve private custom.
31 year old bear is Hubei filial piety moving, it was diagnosed with a small rheumatoid arthritis, has been controlled by hormone drugs. 2 years ago, the local hospital for her implementation of the left hip replacement surgery, taking into account the patient's right side of the hip joint disease is more serious, there is a large area of bone defects, the local hospital recommended to the hospital for treatment. Ms. Xiong after all around, in February 24th this year, after finding the Department of orthopedics Tongji Hospital Professor Xiao Jun.
After admission examination results show that if not timely treatment, bear is likely to lifelong disability.
In order to make the surgery more accurate, the doctor through the CT scan, in accordance with the proportion of 3D 1:1 print out patients with hip joints, and then assess the situation of bone defects. Then according to the patient's hip joint shape in the computer to implement the simulation of hip replacement and determine the size of the acetabulum and bone defect module shape and size, and then print out the required repair module for prosthesis implantation.
Professor Xiao Jun introduction, the treatment of rheumatoid arthritis is the key to early diagnosis and reasonable, timely treatment. If the joint damage occurs, the range of motion can be reduced, and the activity of the joint can be recovered by the joint replacement, and the therapeutic effect is better than 95%. This 3D printing hip replacement surgery is suitable for very severe bone defect.
