Purpose:
Instability following total hip arthroplasty (THA) remains a significant complication. This study aimed to evaluate spinopelvic parameters in Indian patients and the role of functional component positioning in preventing dislocations.
Methods:
This prospective study included 338 patients undergoing primary THA from January 2023 to June 2024. Spinopelvic alignment and mobility were assessed using standing and sitting radiographs, with classification based on the Simple Hip-Spine classification system. Component positioning was tailored to spinopelvic parameters, including robotic-assisted THA in selected cases.
Results:
The mean age was 48 years and most common indication of THA was osteonecrosis of head of femur. Spinopelvic abnormalities were observed only in 12% of patients, lower than in Western populations. Functional component positioning successfully prevented dislocations, with no cases reported at 6 months. PI-LL was negative in 58% with hyperlordosis (PI-LL < -100) in 22% and spinopelvic imbalance (PI-LL > 100) was in 9%.
Conclusion:
Spinopelvic abnormalities are less common in Indian THA patients. Preoperative evaluation and personalized component positioning effectively prevent dislocations.
