Abstract

Background: Adult degenerative disorders of hip and spine are common. The recent studies inconsistently have discussed about the influence of spinal disorders on total hip arthroplasty (THA). In this review, we discussed clearly about these relationships and their effects on the most appropriate position of the acetabular component. Methods: We searched on databases and evaluated the articles about spinopelvic parameters in patients with spinal disorders who needed THA. Results: The literature search showed a prevalence of 21.2 to 60.4 of low back pain (LBP) in patients, who are candidates for primary THA. The coexistence of degenerative disease of hip and spine or other diseases can significantly alter spinopelvic alignment. Accordingly, pain management or any other treatment in these patients requires proper understanding about the biomechanics of the hip and the spinal and their corresponding interactions. In this review article, we discussed about these interactions and their effects on the most appropriate position of the acetabular component. Conclusion: We concluded that counseling sessions among patients, orthopedic surgeons and spine surgeons can result in obtaining the best outcome for these individuals. Level of evidence: I
