ABSTRACT
Objective To observe the clinical effect of percutaneous vertebroplasty f PVP)and percutaneous kyphoplasty(PKP)in the treatment of ostcoporotic vertebral compressive fracture. Methods Forty-two patients with osteoporotic vertebral compressive fractures were treated with PVP or PKP from August 2007 to July 2009.VAS and SF-36 scoring systems were employed to evaluate the Dain and quality of life.X-ray was used to evaluate the vertehral height restoration rate and the kyphosis correction rate.The bone cement leakage was determined based on the Chest X-ray. Results There was staitistical difference on PMMA leakage between PVP and PKP group.VAS and SF-36 scores at 2 wePks and 6months after operation were much better than those counted before operation in both PVP and PKP groups(P<0.05).The VAS and SF-36 scores at 6 months after operation showed no statistical difference in comparison with those before operation between PVP and PKP groups(P>0.05).At tWO weeks after operation,the height restoration rate of the fractured vertebral body(anterior and central column)in the PKP group waa better than that in the PVP group(P<0.05).The kyphotic correction rate in the PKP group was a little better than that in the PVP group(P>0.05).Conclusions In the treatment of osteoporotic vertebral compressive fracture,PVP and PKP have the similar effect on the pain relief,can refresh the height of the fractured vertebral body and correct the kyphotic angel of the fracture level to some extent.PVP has more PMMA leakage than PKP.
ABSTRACT
Percutaneous vertebroplasty (PVP) is a relative new interventional technique, which is widely used in treatment of vertebral collapse caused by vertebral neoplasms and osteoporotic compression fractures. The general technical considerations of PVP techniques are discussed based on authors' experience obtained over 400 patients in the past years in this article, including preparation of PMMA, instrument of PVP, guidance and puncture approaches, and technique of the procedure, etc. The conclusion is that PVP is a safe procedure if the physicians handle it properly.
ABSTRACT
Objective To discuss the value and experience of the percutaneous vertebroplasty (PVP)in the treatment of vertebral body compression fracture(VCF)in aged osteoperosis.Methods PVP was performed in 44 cases with VCF including 28 with single vertebral compressed fracture,12 with double compressed fracture and four with triple compressed fracture,with 67 vertebrae,for clinical and radiologieal evaluation.Results The mean follow-up was 15 months(4-23 months).There could be seen immediate relief of pain in 40 cases,out-of-bed activities at operation day in 19 and out-of-bed activ- ities at second day after operation in 25.Postoperative X-ray showed uniformly distributed bone cement in the vertebral,without leakage.Conclusion PVP is a recommendable method for VCF,for it has ad- vantages of pain relief,vertebrae stabilization,minimal invasion and minor complications.
