Bilateral Hip Replacement Variations; 2. Pelvic and Bilateral Hip Degeneration; 3. Lumbar Spine Compression; L4-5 Vertebral Body Instability with Intervertebral Space Narrowing; 4. Osteoporosis(Figure 1), for the advance treatment, she was referred to the orthopedic department and was diagnosed of "Bilateral Total Hip arthroplasty and osteoporosis. “A surgeon purposed her for the Bilateral Revision Total Hip arthroplasty. A patient underwent preoperative preparation, that includes blood routine test, urine and stool test, electrocardiograph (ECG), and chest X-ray. Her blood routine such as serum creatinine, liver function tests (LFTs), complete blood count (CBC), C-reactive protein (CRP), calcitonin and interleukin 6 (IL-6) tests, erythrocyte sedimentation ratio (ESR) and coagulation test were all normal.
