Abstract:
ObjectiveTo evaluate the relief of pain and daily activities in patients with osteolytic tumor of thoracic lumbar vertebrae by percutaneous kyphoplasty (PKP).MethodsA retrospective study was conducted to review 35 cases of osteolytic tumor of vertebrae treated with PKP.All patients had a refractories back pain while CT and MRI showed osteolytic changes in their vertebrae. The operation involved percutaneously inserting inflatable vertebral body and creating a cavity filled with bone cement.The visual analogue scales (VAS),WHO standards for pain relief and owestry disability index (ODI) were recorded after the procedures.The change of height in abnormal vertebrae and status of postoperative leakage of PMMA were also recorded.These data were followed up after 1 day,1 month and 6 months and analyzed via t student test.ResultsThe total 35 operations were done successfully.All patients got a conspicuous pain relief at 24 h after operation,and no spinal injury or compression was found.The X-ray showed that the vertebrates treated were filled well by cerment.There were significant differences at pain levels[(7.52±0.81)vs(4.31±0.32)],locomotor activity scales (ODI) [(69.45±0.87) vs (54.45±0.85)] and the height of vertebral bodies [(2.0±0.5) mm vs (2.7±0.4) mm] before and after operation (t value was -7.34,-5.32 and -3.36,respectively,P ＜ 0.05).At 6 months,follow up studies showed that clinic therapeutic effects were stabled for odynolysis and locomotor activity scales.The rates of pain relief in 24 h,1 month and 6 months were 80.0 ％ (28/35),85.7 ％ (30/35),82.8 ％ (29/35),respectively.ConclusionPKP is a single safe and effective way to treat osteolytic tumor of thoracic lumbar vertebrae.It can simply,quickly,and effectively relief the pain caused by osteolytic spinal tumor,recover height of the abnormal vertebra,and improve patient's life quality safely with less complications.
