Navigation for total hip arthroplasty
نویسندگان
چکیده
Despite increasing advantages in biomaterials, prosthetic designs, and implant fixation, clinical outcome of total hip arthroplasty (THA) has 10% failure rate after 10 years. Component malposition is well known to be responsible for instability, impingement, excessive wear and early loosening. Computer-assisted procedures are expected to improve the accuracy of the components positioning and also the outcome of total hip replacements. We present the Amplivision system (Amplitude, Porte-du-Grand-Lyon, Neyron, France) that has been used since October 2005 for total hip replacements at our institution. The surgical technique as well as the advantages of this system is described. The Amplivision system allows accurate positioning of the acetabular and femoral components during THA and also the control of leg lengthening, offset and stability.

Novel cemented cup-holding technique while performing total hip arthroplasty with navigation system
Recently, navigation systems have been more widely utilized in total hip arthroplasty. However, almost all of these systems have been developed for cementless cups. In the case of cemented total hip arthroplasty using a navigation system, a special-ordered cemented holder is needed. We propose a novel cemented cup-holding technique for navigation systems using readily available articles. We com...
متن کاملThe use of computer navigation in hip arthroplasty: literature review and evidence today.
Total hip replacement arthroplasty and hip resurfacing are two of the most successful orthopaedic operations performed worldwide. Critical to the success of these operations is the accurate placement of the components. Correct component alignment reduces mechanical wear and the risk of dislocation. Traditionally, correct component alignment relies on the surgeon referencing from the position of...
متن کاملIn-Hospital Outcomes after Hemiarthroplasty versus Total Hip Arthroplasty for Isolated Femoral Neck Fractures
Background: Previous studies suggest total hip arthroplasty may have some benefits compared to hemi-arthroplasty for displaced intracapsular femoral neck fractures in patients more than 60 years of age. The primary research question of our study was whether in-hospital adverse events, post-operative length of stay (LOS) and mortality in patients 60 year of age or older differed between tot...

Introduction: Optimum component positioning and orientation is required to optimize the functional result during total hip arthroplasty for dysplastic hips. Patients and methods: Sixty-two patients (66 hips) including 33 males and 29 females underwent total hip arthroplasty using modular stem prosthesis at an average age of 40.6 years (range 17 to 49 years). Nineteen hips were clas...

Total hip arthroplasty is an increasingly common procedure used to address degenerative changes in the hip joint due to osteoarthritis. Although generally associated with good results, among the challenges associated with hip arthroplasty are accurate measurement of biomechanical parameters such as leg length, offset, and cup position, discrepancies of which can lead to significant long-term co...

Implant positioning is one of the critical factors influencing the postoperative outcome in total hip arthroplasty (THA) [1.2]. In our previous study, we evaluated the Combined anteversion (CA) value in patients who underwent THA using an image-free navigation for the cup with manual adjustment of the stem. Consequently, the AT value showed wide variability [3].Since March 2013, we have measure...
