Although total hip arthroplasty (THA) has proved to be a successful surgical procedure, both prosthetic and bone impingement resulting in dislocation continue to occur. Studies have shown that spine pathology resulting in lumbar stiffness and hip arthritis often coexist. Spinopelvic mobility patterns during postural changes affect three-dimensional acetabular component position, which affects the incidence of prosthetic impingement and THA instability. Several spinopelvic risk factors that may affect THA stability have been identified. Numerous reports recommend performing a preoperative spinopelvic mobility analysis to identify risk factors and adjust acetabular component position accordingly to lessen the risk of impingement. In doing so, acetabular component position is individualized based on spinopelvic mobility patterns. Additionally, functional femoral anteversion, affected by individual femoral rotation patterns during dynamic activities, may contribute to the incidence of impingement. It is important to review the interrelationship between spine and pelvic mobility and how it relates to THA and may reduce the incidence of instability.

Background: Degeneration of the spine may affect pelvic parameters and hip mobility. This study aimed to evaluate the effects of degenerative scoliosis and spinopelvic parameters on hip hemiarthroplasty dislocations.
Methods: A retrospective analysis was conducted on patients who underwent hemiarthroplasty for intracapsular hip fracture over a twenty-year period.

Background: Measuring passive hip flexion range of motion (ROM) is challenging due to compensatory movements. Despite the interest in using functional lateral radiographs for assessing hip mobility, the relationship with passive hip flexion ROM remains unclear. This study aims to elucidate this relationship and clarify spinopelvic parameters and mobility factors influencing variations in passive and radiographic hip flexion ROM.

Introduction: Pelvic incidence - lumbar lordosis (PI-LL) mismatch is often considered when assessing spinopelvic alignment in the sagittal plane. The mismatch is conventionally obtained by measuring 2 separate angles on lateral spinopelvic radiographs. This study describes a simplified approach for assessing spinopelvic mobility and measuring the PI-LL mismatch through the evaluation of the L1-spinopelvis angle (L1SP).

Background: Patients with increased pelvic tilt (PT) are at risk for instability following total hip arthroplasty (THA). Identification of increased PT using anteroposterior (AP) pelvic radiographs could avoid additional spinopelvic radiographs. This study aimed to (1) describe which AP pelvic parameters most accurately estimate sagittal PT, and (2) determine thresholds for these parameters that can identify patients with increased PT.
