prevalence of hip dislocation after total hip arthroplasty in people with or without spine problems

Abstract

The second most common complication following hip arthroplasty (THA) is joint dislocation, which affects up to 11% of patients after primary surgery. Most of the pelvic dislocations are posterior. In the Wolson and Rahimola study, a dislocation rate of 3.2% of THA 10,500 was reported. Various surgical procedures are included in that group; The rate of displacement following reoperation is approximately 25% higher. The incidence in Italy has been reported to be between 0.3 and 10% in primary THA and up to 28% in reoperation. Sah and Esok also noted that converting hip hemiarthroplasty to complete hip replacement results in dislocation of up to 22%. Due to the importance of hip dislocation and the lack of a similar study, we decided to investigate the prevalence of hip dislocation after total hip arthroplasty in people with spinach problems in the Martyrs' Center, which is one of the most important arthroplasty centers in the northwest of the country. Materials and Methods: This descriptive cross-sectional study was performed during the year 2021 by reviewing the records of operated patients in Shohada Hospital in Tabriz. To collect data, after approving the proposal in the ethics committee and receiving permission from the faculty to review the files of the patients studied, a checklist was collected to collect data; Required information included demographic information such as age, BMI, gender, duration of illness, number of surgeries and duration of previous surgery, etc. Then, to evaluate the studied objectives, Chi-square test or Fisher's exact test, Assirman correlation coefficient were used and then the data were entered into SPSS 23 to interpret the data. Results: Having spine problems increased the risk of dislocation after hip replacement 5.41 times, age over 65 years the risk of dislocation after hip replacement 4.21 times, female gender increased the risk of dislocation after hip replacement 1.29 times Body mass index above 25 increases the risk of dislocation after hip replacement 2.41 times, having underlying diseases dislocation after hip replacement 2.1 times, having musculoskeletal problems the risk of dislocation after hip replacement 26.26 Increases 2 times.
