The association between Femoral Tilt and impingement-free range-of-motion in total hip arthroplasty
BACKGROUND There is a complex interaction among acetabular component position and antetorsion of the femoral stem in determining the maximum, impingement-free prosthetic range-of-motion (ROM) in total hip arthroplasty (THA). By insertion into the femoral canal, stems of any geometry follow the natural anterior bow of the proximal femur, creating a sagittal Femoral Tilt (FT). We sought to study ...
متن کاملEffect of femoral offset on range of motion and abductor muscle strength after total hip arthroplasty.
At a minimum of one year after operation, we studied 64 patients with 86 total hip arthroplasties (THA) by standard anteroposterior hip and pelvic radiographs and measurement of range of motion and of isometric abduction strength. The femoral offset correlated positively with the range of abduction (p = 0.046). Abduction strength correlated positively with both femoral offset (p = 0.0001) and t...
متن کاملAdjusting the combined anteversion to maximize range of motion in total hip arthroplasty: Acetabular side or femoral side, which adjustment is more effective?
INTRODUCTION: Cup and stem positioning correlates each other in total hip arthroplasty (THA), and it is believed that optimal combined anteversion (CA), which is a sum of cup and stem anteversion (AV) angle, is about 40° – 60°. However, there are few studies that have compared which adjustment is more effective, changing a cup or a femoral stem to optimizing CA and increasing ROM. In this study...
متن کاملFemoral component wear in retrieved hip prostheses.
We retrieved 159 femoral heads at revision surgery to determine changes in surface configuration. Macroscopic wear of the head was observed in three bipolar hip prostheses as a result of three-body wear. There was a considerable change in surface roughness in the internal articulation of bipolar hip prostheses. Roughness in alumina heads was almost the same as that in new cobalt-chromium heads....
متن کاملAccuracy of Combined Anteversion in the Combined Anteversion Technique with Image-free Navigated Total Hip Arthroplasty
In recent literatures dealing with optimization of prosthetic alignment in total hip arthroplasty (THA), the concept of combined anteversion (CA), which is the sum of acetabular anteversion (AV) and femoral antetorsion (AT), has been addressed. Widmer attempted to determine the optimal CA using a computer simulation study . He proposed the “new safe zone” for the CA value to achieve essential r...
