Methods 40 patients,45 hips with various diseases were treated by total hip joint replacement from Jan 2000 to Sep 2001.Before operation, the perpendicular length from center of femoral head to the summit of great tuberosity and the tip of less tuberosity to the line of bilateral ischial tuberosity were measured; the length from anterior superior iliac spine to medial malleolus were measured at same time.Leg length was decided and corrected according to these lines. Results Before operation, shortening of limbs were presented in 39 hips, 1 to 4 cm, average 2.4 cm.After operation, discrepancy of both legs was 0～0.8 cm.Apparent limps were not observed in all patients. Conclusion This measurement is a useful method to maintain and recover leg length in total hip joint replacement.展开更多

Uncemented THR was introduced to improve the long term results and in particular the results in younger, higher functioning patients. There has been controversy about the value of uncemented compared to cemented THR although there has been a world-wide trend towards uncemented fixation. Uncemented acetabular fixation has gained wide acceptance, as seen in the increasing number of hybrid THR in joint registries, but there remains debate about the best mode of femoral fixation.In this article we review the history and current worldwide registry data, with an in-depth analysis of the New Zealand Joint Registry, to determine the results of uncemented femoral fixation in an attempt to provide an evidence-based answer as to the value of this form of fixation.展开更多

Recent literature regarding the DAA was searched and specific claims investigated including improved early outcomes, speed of recovery, component placement, dislocation rates, and complication rates. Recent literature is positive regarding the effects of total hip arthroplasty with the anterior approach. While the data is not definitive at present, patients receiving the anterior approach for total hip arthroplasty tend to recover more quickly and have improved early outcomes. Component placement with the anterior approach is more often in the "safe zone" than with other approaches. Dislocation rates tend to be less than 1% with the anterior approach. Complication rates vary widely in the published literature. A possible explanation is that the varianceis due to surgeon and institutional experience with the anterior approach procedure. Concerns remain regarding the "learning curve" for both surgeons and institutions. In conclusion, it is not a matter of should this approach be used, but how should it be implemented.展开更多

A method of acquiring the point data on the surface of the hipbone using the reverseengineering technology is presented. After analyzing the acetabulum surface fitting error, arotation ellipsoid CAD model is applied to fit the acetabulum surface, and then optimizationtechnique is used to find the geometric parameters of the model. The fitting error between thesphere and rotation ellipsoid is compared and gets the result that the fitting error of rotationellipsoid is smaller than sphere, and the rotation ellipsoid can describe the shape of theacetabulum better.展开更多
