Abstract

Abstract:

BACKGROUND: Vertebroplasty (PVP) and kyphoplasty (PKP) are important methods for the treatment of osteoporotic vertebral compression fractures in the elderly. Although bone cement has certain liquidity and vertebral fractures are often in different situations, bone cement leakage rate is still high.

OBJECTIVE: Based on the theoretical discussion and clinical analysis, to study the theoretical causes of bone cement leakage and effective prevention methods.

METHODS: A total of 162 cases (186 vertebrae) were treated with three methods of vertebroplasty. Group A: 64 cases with 78 vertebrae were treated with conventional cemented vertebroplasty; Group B: 57 cases with 65 vertebrae were treated with cemented vertebroplasty using cement pump; Group C: 41 cases with 43 vertebrae were treated with balloon kyphoplasty. The leakage of bone cement was observed in three groups.

RESULTS AND CONCLUSION: Of the 186 vertebrae, postoperative bone cement leakage occurred in 25 vertebrae, with the leakage rate of 13% (25/186). Group A had bone cement leakage in 11 vertebrae, and the leakage rate was 14% (11/78). Group B had bone cement leakage in 8 vertebrae, and the leakage rate was 12% (8/65). Group C had bone cement leakage in 6 vertebrae, and the leakage rate was 14% (6/43). There was no significant difference among the three groups in the leakage rate of bone cement (P > 0.05). That is to say, the causes of bone cement leakage are not completely controllable, and the leakage position has some randomness. Strict and careful imaging monitoring is an intuitive method to prevent bone cement leakage.
