Abstract:

BACKGROUND: Currently, total hip arthroplasty is a recognized and preferred method for treatment of adult congenital acetabular dysplasia, however, there were lack of ideal evaluation methods to precisely solve acetabular reconstruction in the process of treatment.
OBJECTIVE: To investigate the evaluating effects and biological properties of computer aided technology in adult acetabular dysplasia after total hip arthroplasty.
METHODS: The clinical data from 80 patients with adult congenital acetabular dysplasia who received the treatment at Department of Bone and Joint Surgery, Changhai Hospital, Second Military Medical University of Chinese PLA from January 2015 to August 2015 were selected and analyzed. All the enrolled patients underwent total hip arthroplasty. All the patients were randomly divided into control and computer-aided technology groups. CT scanning was conducted in these two groups before replacement. Three-dimensional reconstruction measuring and surgical rehearsal on the acetabular site were conducted using M3D visualization software in the computer-aided technology group. The effects and biological properties of total hip arthroplasty were compared between these two groups.
RESULTS AND CONCLUSION: Patients in these two groups primarily healed after replacement. The excellent and good rate, Harris score after treatment, acetabular component, valgus angle and anteversion in the computer-aided technology group were significantly higher than those in the control group (P < 0.05). The acetabular cup abduction angle offset degrees, acetabular cup anteversion offset degrees, and the incidences of complications after replacement were significantly decreased compared with those in the control group (P < 0.05). These results suggest that the effect of computer-aided evaluation in adult acetabular dysplasia after total hip arthroplasty is ideal, and can accurately grasp the true acetabular anatomical characteristics and the corresponding relationship with the prosthesis, so as to help patients to choose the proper acetabulum and acetabular prosthesis and reconstruction ways and improve the biological performance of acetabulum after replacement, with a high clinical value.
