Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The postoperative implant position will evaluate using the 3D computed tomography (Somatom Sensation 64, Siemens Healthcare Sector, Forchheim, Germany). The accuracy of the navigation system will be measure between that what intraoperativly displayed by the navigation system postoperatively evaluate in the 3D computed tomography. A significant inaccuracy is postulated by a difference of more than 5 °. | — |
Secondary
| Measure | Time frame |
|---|---|
| The influence of the BMI and the soft tissue overlying the APP on the accuracy of navigation systems will be tested by using a statistical correlation. In the absence of a significant correlation assumes a lack of influence. | — |
