Percutaneous vertebroplasty or percutaneous kyphoplastyfor Kummell’s disease with vertebral posterior wall collapse：how to treat individually? / 中国组织工程研究

ABSTRACT

BACKGROUND:StageIorIIKummel’s diseaseisusualy suggested to be treated with percutaneous vertebroplasty (PVP) orpercutaneous kyphoplasty (PKP). Stage IIIKummel’s diseasewith neurologic deficit is treated with open decompression, cement-augmented combined with internalfixation. However, surgical options for stage IIIKummel’s diseasewithdural saccompression butwithnonervous symptoms arein disputeand rarely reported. OBJECTIVE:To investigatethesurgical options of Kummel’s disease with vertebral posterior walcolapse. METHODS:Fourteen patients with Kummel’s disease with vertebral posterior wal colapse wereenroled as experimental groupandtreated with PVP or PKP based on the degree of postural reduction.Another28 patients with osteoporotic vertebral fracture as control group were treated with PKP. Thenalpatients were folowed up to observe vertebralheight, Cobb angle, visual analog scale and the Oswestry disability index. RESULTS AND CONCLUSION:After folowed up for 10 to 42 months, therestoredvertebralheight, Cobb angle, visual analog scale and Oswestry disability index were significantly improved inthetwo groups (P 0.05). These data suggest that based on the degree of postural reduction, individualizedPVP or PKP for Kummel’s disease with vertebral posterior wal colapsecanattain satisfactoryoutcomes.
