PREOPERATIVE ANALYSIS OF THE BARYCENTRE AT THE PATIENTS WITH TOTAL HIP ENDOPROSTHESIS
Abstract
The present study analyzes the projection of the barycentre within the support polygon and the distribution ofthe body weight on the lower limbs compared to the two samples of subjects. For sample A, the assessment was unique,while for sample B there was a preoperative assessment. This way, we will analyse the loading and soliciting degree atthe level of preoperative hip joints, with a subsequent identical postoperative analysis for the study sample.In this sense, we have used the GPS400 stabilometric platform that through the pressure sensors test both therepartition of the body weight on the lower limbs, analysing at the same time the oscillations that appear during theorthostatic position.The principle of the stabilometric method is to analyse the barycentre in orthostatic position. The purpose ofthe postural assessment is to diagnose the deviations of the mechanical loading charges at the level of the hips, theefficiency of the surgery and that of the recovery programs.We have conducted a prospective study on a number of 21 healthy persons with no previous problems at thelevel of hip joints or lower limbs and 17 patients diagnosed with coxarthrosis and an indication for total hiparthroplasty, in the period September 19, 2009 – July 30, 2011. It took place at the Orthopaedics Clinic of the ClinicalRecovery Hospital in Iaşi.In conclusion, we consider that a rigorous and complete analysis at the level of hip articulation may bringadditional important information in case of the complex preoperative examination, thus contributing to the futuretherapeutic behaviour.
