Restoration of Some Anatomical Dimensions By Spiron Short Stem Hip Replacement Applied To Vietnamese People

Abstract

Background: The process of using proximal bone in hip arthroplasty will allow the remaining bone to be preserved in future surgeries. To take advantage of these advantages, many types of short stem prosthetics have been developed in recent years. The obtained survey parameters combined with the obtained anatomical parameters shown that the Spiron joint is suitable when applied to adult Vietnamese.Research subjects and methods: The anatomical dimensions of the hip joint related to Spiron joint replacement were analyzed by the authors.Results: The anatomical results with Spiron showed that the acetabular average diameter and tilt angle were 49.77 mm and 41.55°. The femoral neck-to-body angle, the femoral upper-neck diameter, the distance from the crest to the hard shell along the femoral neck axis was on average 131.52°, 34, 32mm, and 51.39mm, respectively. The offset distance from the center of the crest to the axis of the femur is 38.33mm. These parameters show the working ability as well as stability when replaced by the Spiron joint.Conclusion: When applied to adult Vietnamese, the femoral neck diameter is consistent with the Spiron diameter. Preoperative planning is needed to check the femoral neck angle and femoral neck length prior to surgery to see if the Spiron joint replacement is eligible. The findings of this study support the assumption that it is feasible to use Spiron prostheses in joint replacement in Vietnamese adults.
