Introduction: Total hip arthroplasty is a common, well-controlled procedure. But its practice is still insufficient in low-income countries.
The objective of our work was to evaluate the functional and radiological results of patients treated during fairground surgery.
Patients and Methods: This series of cases concerns 31 total hip arthroplasties implanted by anterior (15) and anterolateral (16) approach on standard table, in three editions, by three surgeons. The functional assessment was made by the scores of Devane, de Postel, Merle d’Aubigné (PMA) and Harris and the level of subjective patient satisfaction, the radiographic assessment concerned the positioning of the implants.
Results: The perioperative complications were hemorrhagic shock (01), fractures of the greater trochanter (05), subcutaneous hematoma (07), In 05 cases of lower limb overlengthening, 2 were poorly tolerated. The Devane activity score increased from 70.97% of Grade ≤2 to 83.87% of Grade ≥3. The PMA score had gone from 90.32% patients at most poor to 70.97% at least good, and Harris Hip Score was excellent or good in 74.19% and 96.77% had a level of subjective satisfaction excellent or good matching with the Harris. The average cup abduction angle was 44.51° (17-62°), 67.75% of them were in the safe zone. The femoral offset was assessable in 21 patients, 16 of whom were satisfactory. 35.48% of the femoral stems were varus. An upper anterior dislocation occurred at day-56 post-operative.
Conclusion: These three editions of fairground surgery present in their vast majority all the technical and technological indicators of a successful operation with a good prognosis and have enabled the return to more than acceptable physical activity for all beneficiaries.
The low hemorrhagic nature of the minimally invasive anterior and anterolateral approaches makes them an asset to acquire for our countries frequently exposed to shortages of blood to transfuse.
