Clinical analysis of small-dose bone cement prophylactic strengthening of sandwich vertebra in the treatment of "sandwich" osteoporotic vertebral compression fracture

ObjectiveTo investigate the necessities of the small-dose bone cement prophylactic strengthening of sandwich vertebra in the treatment of "sandwich" osteoporotic vertebral compression fracture during percutaneous kyphoplasty.

MethodsA total of 50 "sandwich" osteoporotic vertebral compression fracture patients treated with percutaneous kyphoplasty were selected, 29 cases were treated with the small-dose bone cement prophylactic strengthening of sandwich vertebra based on the conventional percutaneous kyphoplasty(observation group) and 20 cases were treated without sandwich vertebrula strengthening(control group).The incidence of sandwich vertebral fractures was followed up.

ResultsThe differences of the preoperative bone mineral density, age and body mass index were not statistically significant between two groups(P>0.05).One case with fracture in the observation group and 8 cases with fractures in the control group were identified, and the difference of postoperative fracture rate between two groups was statistically significant(χ²=4.73, P < 0.05).

ConclusionsIn the conventional percutaneous kyphoplasty of "sandwich" osteoporotic vertebral compression fracture, the small-dose bone cement prophylactic strengthening of sandwich vertebra can reduce the risk of postoperative sandwich vertebral fractures.
