BIOMECHANICAL ASSESSMENT AND MODELLING OF TOTAL HIP ARTHROPLASTY PATIENTS

Many surgical decisions taken in the operating theatre are based on the experience and the expertise of the surgeon. Using biomechanical and computational data can provide additional information for the surgeon. By carrying out biomechanical trials pre-operatively as well as a full three dimensional analysis of the skeletal structure of the patient, it is possible to provide the surgeon with clinical data that can support the decision making with regards of fixation method, type of implant and size to name a few. In the presented project a description is provided of the pre-operative assessment of primary total hip patients in Iceland and how the analysis is helping to prevent periprosthetic fractures.Over 70 patients undergoing primary total hip arthroplasty in Iceland were recruited for the study1. Gait analysis was performed on the patients using a pressure plate in conjunction with two synchronised video cameras. In addition, EMG was recorded from three muscles: Rectus femoris, Vastus lateralis and Va...
