To retrospectively analyze and compare the clinical efficacy of vertebroplasty in the treatment of recessive osteoporotic vertebral fractures with different cement distribution.

According to the shape of bone cement after treatment, the patients were divided into two groups: sponge distribution group and lump distribution group. The patients in the two groups were compared following indexes: general condition, basic condition during operation, evaluation of macnab effect after operation, VAS score and ODI score before and 2 months after operation.

130 cases of tacit osteoporotic vertebral fractures were treated by vertebroplasty. There were 62 cases in sponge distribution group and 68 cases in lump distribution group. There was no difference between the two groups in general condition. ①There was significant difference in the amount of bone cement injection between the spongy distribution group and the mass distribution group (P<0.01). The amount of bone cement injection in the spongy distribution group was less than that in the mass distribution group. ② The VAS score and ODI score of the two groups were lower than that of the group before operation (P<0.01), and the VAS score and ODI score of the sponge distribution group were lower than that of the lump distribution group (P<0.01). ③ In the evaluation of the curative effect of macnab, the excellent rate of sponge distribution was 95.16%; the excellent rate of lump distribution group was 83.82%; the excellent rate of sponge distribution group was better than that of lump distribution group (P<0.05).

In the treatment of recessive osteoporotic vertebral fracture by vertebroplasty, compared with mass bone cement injection, sponge bone cement injection can effectively reduce the amount of bone cement, and achieve better clinical results, which is worthy of clinical promotion.
