Case: A 63-year-old woman with lumbar degenerative kyphosis who had undergone total hip arthroplasty 34 months previously presented after having multiple episodes of anterior hip dislocation; evaluation also revealed progressive osteoarthritis in the contralateral hip joint. The patient was managed with sagittal correction with pedicle subtraction osteotomy, which resulted in optimal positioning of the acetabular component and an upright posture. The patient had had no additional dislocation events in the involved hip and had reduced pain in the contralateral hip at the time of the 2-year follow-up.

Conclusion: It is important to evaluate and address preexisting sagittal imbalance before performing total hip arthroplasty. However, for patients with neglected sagittal imbalance resulting in recurrent hip dislocation after total hip arthroplasty, sagittal deformity correction may be beneficial.
