[Anatomical and functional results of total hip prosthesesat Kati University Hospital].

Introduction: Hip prosthetic surgery is a commonly performed procedure in orthopedic trauma. It has changed the prognosis of traumatic, degenerative and inflammatory hip diseases.

Objective: The aim of this work was to evaluate the functional and anatomical results of a series of total hip replacements in our department in the short and medium term and to compare them with the literature.

Patients and methods: This was a retrospective descriptive and analytical study of a series of 96 total hip replacements performed at the University Hospital of Kati, from January 2019 to December 2021. Functional discomfort was assessed in all patients before and after surgery. The prostheses used were of the Aston, AK, Surgival, Evolutus and Sharma types. The anatomical results were assessed by radiological criteria and the functional results by Postel Merle d'Aubigné criteria.

Results: In our study, 96 hips were operated on by total prosthesis in 91 patients, including five bilateral cases. The patients were 49 men and 42 women. The average age was 46.9 years. Coxarthrosis associated with necrosis of the femoral head was the most frequent indication for arthroplasty (n=51), followed by femoral neck fracture (n=26). The inclination of the cup was anatomical in 73.3% of cases. The mean femoral offset was 44.1 mm with extremes of 26 and 59 mm. Cup anteversion was normal in 79.4% of cases. The mean preoperative PMA score increased from 5.2 (0 and 15) to 16.9 (4 and 18) late postoperatively. Our results were satisfactory in 89% of cases.

Conclusion: Total hip arthroplasty allows, in the vast majority of cases, to recover indolence and perfect functionality of the hip.
