A number of hospitals manage their own bone banks, such as the VU university medical center in Amsterdam, where an orthopaedic bone bank has been established. This VUmc orthopaedic bone bank contains only femoral heads of suitable patients who underwent total hip replacement surgery. The advantage of possessing a bone bank is that the hospital always has its own supply of donor bone material; this may also be a financially viable strategy for hospitals carrying out many procedures for which donor bone material is required.
