Abstract:

BACKGROUND: Most studies suggest that the spiral-type acetabulum of total hip arthroplasty (THA) could provide better stability than the press-fit acetabulum.
OBJECTIVE: To compare the effects of press-fit acetabulum and spiral-type acetabulum in THA.
METHODS: The retrospective analysis on the clinical data of 39 THA patients with press-fit acetabulum and spiral-type acetabulum was preformed. 
RESULTS AND CONCLUSION: ①All cases were followed-up for 4-51 months, the average time was 32.6 months. ②Harris scores: Postoperative Harris scores were significantly improved than preoperative in the final follow-up (P < 0.05), and the score of the spiral-type acetabular group was slightly higher than that of press-fit acetabular group, but the difference was not significant. ③Adverse reactions: The postoperative complications of the press-fit acetabular arthroplasty group included looseness of hip prosthesis 1 case after 1 year, ambulation pain 3 cases, osteogenesis around acetabular prosthesis 6 cases, translucent around acetabular prosthesis 3 cases, osteosclerosis around acetabular prosthesis 1 case and bone resorption around acetabular prosthesis 1 case; the spiral-type acetabular group included osteogenesis around acetabular prosthesis 3 cases, translucent around acetabular prosthesis 1 cases and bone resorption around acetabular prosthesis 1 case. Therefore, the initial stability of the spiral-type acetabular prosthesis was better than that of the press-fit acetabular prosthesis.
