A Surgical Kit For Hemiarthroplasty Hip Replacement

摘要

The invention concerns a surgical kit provided for performing a hip hemiarthroplasty, in which a femoral head 1 is fitted directly into a socket reamed into the acetabular without any permanent liner or prosthetic acetabular being implanted. The reamer is used to ream out the acetabular until cancellous bone is exposed so that it bleeds liquid containing stem cells. By selecting the size of the femoral head in accordance with the characteristics of the patient, the pressure imposed on the liquid is in the range between 0.5 and 2MPa. This causes the stem cells to produce new cartilage between the bone and femoral head.
