Patients diagnosed to have a cementless hip arthroplasty, free walking and standing without support.
• BMI = 30
• previous endoprosthetic interventions (ipsilateral and contralateral hip, knee and ankle joints)
• Surgical interventions on the musculoskeletal system during the previous 6 months.
• ASA-Klassifikation > 2
• progressive joint inflammation or destructive rheumatoid arthritis
• Neurologic diseases (z.B. Morbus Parkinson, stroke with paralysis, Muscular dystrophy, Epilepsy, Multiple Sclerosis, Paraneoplastic Neurologic Syndrom (PNS), Tremor, Alzheimer's disease, Huntington's chorea, Polio, cerebral palsy)
• injuries of the lower extremities
• no informed consent
• Patients with x-ray images which can be used for planning.
• Patients who can not stand still for about 10 seconds as one of the requirements for EOS
Study & Design
- Study Type
- observational
- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method The prosthetic sizes (cup and stem size) predicted with the TraumaCad® software in the one group and with the hipEOS software for the other group will be compared to the actual implanted sizes.
- Secondary Outcome Measures
Name Time Method 1. The correlations between the static situation, defined by leg length discrepancy, degree of leg misalignment and degree of rotational deformity (calculated by SterEOS® on the postoperative EOS image), and the dynamics of gait (defined by joint loads, spatial-temporal parameters and range of motion).<br>2. COMP concentration from the blood samples.
