Cement implantation syndrome characterized by hypotension, hypoxemia, cardiac arrhythmia or arrest has been reported in the literature. The purpose of the present study was to monitor blood pressure soon after cementing. The present study includes 178 cases 204 joints of primary THA with an average age at operation of 64.5 years old (ranging 35 to 89). Under general anesthesia, both components were cemented using antero-lateral approach. Systolic arterial blood pressure during cementing acetabular and femoral components was monitored until 5 minutes with 1 minute interval. The maximum regulation ratio (MRR) was calculated as (maximum change blood pressure – blood pressure before cement insertion) divided by blood pressure before cement insertion.Background
Methods
Impaction bone grafting (IBG) using a circumferential metal mesh is one of the options that allow restoration of the femoral bone stock and stability of the implant in hip arthroplasty. Here we examined the clinical and radiographic outcome of this procedure with a cemented stem and analyzed experimentally the initial stability of mesh–grafted bone–cemented stem complexes. We retrospectively reviewed 6 hips (6 patients) that had undergone femoral revisions with a circumferential metal mesh, impacted bone allografts, and a cemented stem. The mean follow-up period was 2.9 years (range, 1.4–3.8 years). Hip joint function was evaluated with the Japanese Orthopaedic Association hip score, and radiographic changes were determined from radiographs. The initial resistance of cemented stem complexes to axial and rotational force was measured in a composite bone model with various segmental losses of the proximal femur.Background
Methods
One of the drawbacks of cemented total hip arthroplasty (THA) is aseptic loosening after long period, major reason for which is bioinertness of PMMA bone cement. To improve longevity of THA, interface bioactive bone cement (IBBC) technique which is characterized with smearing hydroxyapatite (HA) granules just before cementation has been used in our institute. Smooth-surfaced triple-tapered Titanium-alloy stem (T) and Exeter stem (E) have been used consecutively in the different period. Objective of the present study was thoroughly comparing two stems clinically and radiologically.Purpose
