Summary

In this study, the investigators retrospectively collected DDH case data of THA assisted by AI 3D planning and THA assisted by traditional planning. The compliance between preoperative planning and the type of prosthesis used in the operation, the position of the acetabular prosthesis, the correction of LLD and the postoperative joint function score were analysed to evaluate the short-term effect of AI combined with preoperative 3D planning in THA for DDH.

Conditions

• Developmental Dysplasia of the Hip

Interventions

Type	Name	Description
PROCEDURE	artificial intelligence (AI)-assisted three-dimensional preoperative planning technology	In the AI planning group, AI was used to assist in the 3D planning to complete the preoperative design. Preoperative planning was performed by two experienced surgeons and without the chief physician to ensure that the results of the preoperative planning did not affect the selection of intraoperative procedures and prosthesis size.
OTHER	X-ray film template for 2D planning	A traditional X-ray film template was used to complete the preoperative design in the traditional planning group. The position and size of the prosthesis, the level of femoral neck osteotomy, the length of the LLs and the restoration of eccentricity were estimated by X-ray. A plastic template provided by the manufacturer was used to take the line of the lower edge of the teardrop on both sides as the horizontal reference line, and the acetabular template was placed at 40 abduction on the inner edge of the teardrop so that the lower edge of the acetabular cup was adjacent to the teardrop. An appropriate type of acetabular component was selected to fill the acetabulum and maintain coverage, and the femoral component that best matched the femoral medullary cavity was chosen. The height of the osteotomy was determined, and the planning model was recorded after the surgeons were happy with the placement and outcome.
