Inclusion criteria
Inclusion criteria: Patients diagnosed to have a cementless hip arthroplasty, free walking and standing without support.
Exclusion criteria
Exclusion criteria: • 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
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 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
| Measure | Time frame |
|---|---|
| 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). 2. COMP concentration from the blood samples. | — |
