Implant Positioning

Background. In primary and revision total hip arthroplasty, to prevent perioperative complications, the prediction of the optimal implant size is essential. Using three-dimensional computed tomography-based postoperative evaluation software, we explored the accuracy and the precision of measurement of the size, alignment, and position of the prosthetic components after total hip arthroplasty. Methods. Using postoperative evaluation software, the postoperative computed tomography data from 20 hips in 20 patients were evaluated. The component size, alignment, and three-dimensional positioning of the cup and stem were assessed. The concordance rates of the component, repeatability (intraobserver reliability), and reproducibility (interobserver reliability) of postoperative evaluation were calculated. The radiographic inclination and radiographic anteversion of the cup, anteversion, varus–valgus angle, and flexion–extension angles of the stem were measured for alignment. The implant positioning was measured along three axes, namely, X-axis (transverse), Y-axis (sagittal), and Z-axis (longitudinal). Results. The concordance rates of all parts are above 94%. The intraobserver and interobserver intraclass correlation coefficients of alignment measurement were very good for both cup (0.879–0.964) and stem (0.973–0.996). The intraobserver and interobserver intraclass correlation coefficients of cup positioning were very good (0.961–0.987) for all axes. The intraobserver and interobserver intraclass correlation coefficients of implant positioning were very good for the stem (0.879–0.995) for all axes. Conclusions. Computed tomography-based postoperative evaluation software was able to evaluate the size and position of total hip implants with high reproducibility.

Iliopectineal Bursa

Our goal is to draw attention to the inflammation of the iliopectineal bursa being a rare condition, which can cause lower limb swelling and anterior pain of the hip even years after total hip arthroplasty. A 67-year-old woman was admitted seven years after hip arthroplasty (cemented total endoprosthesis [TEP]) with swelling and feeling of excessive fullness of the lower extremity and with tolerable anterior hip pain. The physical examination and blood tests were non-specific for septic condition. Ultrasound showed a cystic mass in the inguinal region with a direct contact to the common femoral vein. Deep vein thrombosis was excluded. The single-photon emission computed tomography-computed tomography (SPECT-CT) was administered to decide the surgical plan, either making a bursa extirpation or making revision hip arthroplasty. The SPECT-CT excluded the possibility of aseptic loosening. Methylene blue was injected into the bursa intraoperatively which did not enter the strong pseudo-capsule of the joint and, therefore, we did not administer revision of the TEP, and the bursa was extirpated. Two weeks after the operation, the patient had no pain, was able to walk, and the swelling decreased. Four months after surgery, the pain and feeling of fullness disappeared, with minimal lower limb swelling. In conclusion, in case of increasing complaints of patients who left years behind without any problem following total hip arthroplasty, the pathogenic role of the iliopectineal bursa should be taken into account, after excluding more frequent causes such as aseptic loosening or periprosthetic joint infection. As long as we consider about a rare disease, we can find a solution to the patient’s complaint sooner.
