Prospective explorative study for the investigation of short-term and medium-term outcomes regarding bone mineral density changes after revision hip arthroplasty making use of bone impaction grafting. Outcome measurements will include objective and subjective clinical data, complications and adverse events, radiographic data measurements recorded at several postoperative intervals.

  Show Detailed Description


Ages Eligible for Study:   35 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. revision hip arthroplasty with acetabular defects eligible for bone impaction grafting
  2. Diagnosis: acetabular osteolytic defects after primary total hip arthroplasty, planned for revision hip arthroplasty with bone impaction grafting.
  3. Patient is between 35 and 75 years old.
  4. Patient is expected to recover completely.
  5. Patient is willing and able to come to follow-up examinations.
  6. Patient has signed an informed consent.

Exclusion Criteria:

  1. Infection of the hip joint or distant infection (may cause hematogenous spread to the implant site)
  2. Hip fractures
  3. Patient is younger than 35 years or older than 75 years.
  4. Patient is not willing and/or able to come to follow-up examinations
  5. Patient has not signed an informed consent
  6. Pregnancy

Relative contra-indications:

With regard to the patient's general health:

  1. Metabolic disorders or medication (e.g. steroids) which may impair bone formation
  2. Osteomalacia
  3. Disorders of the immune system, caused by disease or immunosuppressive medication which increase the risk of infection.
  4. Poor prognosis for good wound healing: decubitus ulcer, end-stage diabetes, severe protein deficiency and/or malnutrition
