Article Synopsis
- The study compares different CT protocols for planning total hip arthroplasty to assess radiation exposure and image quality.
- All 390 CT scans provided adequate quality for THA planning, with the lowest radiation exposure noted in scans using automated voltage preselection.
- Automated voltage preselection reduced radiation doses by 18.2% while maintaining reliable image quality, emphasizing its effectiveness in preoperative imaging.
Article Synopsis
- The demand for total hip arthroplasties is increasing, yet complications like dislocations and infections persist as significant issues.
- Using minimally invasive techniques and modular implants can improve outcomes by allowing precise adjustments in femoral offset and leg length with thorough preoperative planning.
- A 3D approach with computed tomography (CT) offers superior assessment of hip geometry and bone quality, and better imaging practices can minimize radiation exposure while ensuring effective communication between surgeons and radiologists.
Computed tomography (CT) was used for preoperative planning of minimal-invasive total hip arthroplasty (THA). 92 patients (50 males, 42 females, mean age 59.5 years) with a mean body-mass-index (BMI) of 26.

We implanted 28 cementless, axis-coupled total endoprostheses with hinging (WEKO prosthesis, Implant-Service GmbH, Hamburg, Germany) in 8 women (mean age 62 (47-80) years) suffering from rheumatoid arthritis. The mean follow-up period was 15 (12-18) months, and the evaluation was based on objective criteria, including joint motion, ulnar deviation of the long fingers, grip strength, radiographic migration and torsion of the prostheses, as well as the patients' subjective satisfaction.

Methods: Forty uncemented anatomic physiologic (APH, Implant-Service Vertreibs-GmbH, Hamburg, Germany) wrist prosthesis implantations performed in 40 patients were reviewed. The mean follow-up period was 52 months (range, 24-73 mo) and the following parameters were examined: radiographs, grip strength, range of motion, and patient's satisfaction.
