OBJECTIVE: To investigate the mid-term clinical efficacy of two acetabular revision methods in the treatment of severe Paprosky type Ⅲ acetabular bone defects.
METHODS: Clinical data of patients with severe acetabular defects who underwent surgical treatment were collected from July 2012 to March 2019,including 8 males and 11 females,all belong to Paprosky type Ⅲand underwent unilateral hip joint revision;12 cases(Group A) underwent revision using tantalum metal augment combined with porous biological tantalum cup,and 7 cases(Group B) underwent revision using titanium mesh compression bone grafting combined with cement prosthesis. Record the patient's surgical times,bleeding volumes,and complications,evaluate preoperative and postoperative X-rays as well as Harris scores.
RESULTS: The average surgical time and intraoperative blood loss in Group A were (135.00±20.23) min and (828.57±213.81) mL,respectively. The Group B were(162.86±16.07) min and (1557.14±439.16) mL,respectively. The difference between two groups was statistically significant(P<0.05). The follow-up period ranged from 2 to 12 years. At the end of the follow-up,the Harris score in Group A increased from (36.25±6.88) scores to(82.67±7.16) scores (P<0.05);the Harris score in Group B increased from (33.29±5.22) scores to (79.29±5.62) scores (P<0.05). Among all patients,only 1 case had postoperative periprosthetic fracture,3 cases had lower limb venous thrombosis,and the rest had no neurovascular injury,infection,or early prosthesis loosening.
CONCLUSION: the two acetabular revision methods can achieve satisfactory mid-term clinical efficacy in the treatment of Paprosky type Ⅲ severe acetabular bone defects.
