THA Instability: The Effects of Sagittal Plane Balancing and Decreased Pelvic Motion A Case Report
Abstract Case: We present a case of recurrent total hip arthroplasty (THA) instability in a 63-year-old female with several prior lumbar spine fusions. She underwent multiple revision THAs for peri-prosthetic joint infection (PJI), peri-prosthetic fracture, and recurrent instability- she ultimately required a constrained liner for definitive treatment. Conclusion Instability following THA may be exacerbated by surgical correction of sagittal plane imbalance. Patient counseling, implant selection, component positioning, and pre-operative planning are essential to ensure clinical success.
