Description
Jiaxin Dong and colleagues describe, in a 2026 case report, staged surgery for a young man whose hip had fused solid. Severe hip-spine deformity tied to spondylitis, a stiffening spine disease, framed the case. A fused hip plus a crooked spine throws off alignment of back, pelvis, and hip. Standard surgery here lacks precision and causes heavy trauma. The team used AI planning with navigation and a gentler hip operation.
Stage one replaced the hip through a front approach, guided by the plan. Stage two corrected the spinal curve, planned with a 3D printed model. Thirty months later, hip and general health scores had risen by large margins, and spine measures improved. X-rays showed the hip cup sat at the angles the plan had predicted, with good joint adaptation across back, pelvis, and hip. The authors present the digital, staged route as a model for similar cases.
