Reoperations After Soft Tissue Release for Spastic Hip Displacement: Which One Matters More-Migration Percentage, Acetabular Index, or Motor Function?

Listen to this summary

The authors aimed to identify predictors of reoperation after soft tissue release (STR) for hip displacement in patients with cerebral palsy, specifically comparing the significance of migration percentage (MP), acetabular index (AI), and motor function. Their findings revealed that a higher preoperative AI was a more reliable predictor of reoperation than MP, suggesting that AI should be prioritized in preoperative decision-making for these patients.
