Treatment Of Spinal Compressive Fracture Patients With Osteoporosis By Means Of Percutaneous Kyphoplast

Objective:Through an analysis of the effect of PKP(percutaneous kyphosis plasty)for aged osteoporotic spinal multiple fracture to demon-strate the importance of the selection of responsible veterbal body.Methods:Retrospective analysis of Second Affiliated Hospital of Dalian Medical University between 2007-2009, Forty-five patients (fifty-tow vertebrae)of osteoporotic vertebral compression fracture had applied vertebral body balloon-type expander for expansion of the diseased vertebrae, and bone cement filling, through the pain visual analogue score(VAS)compared before and after surgery and the changes in vertebral height and Cobb angle and sum up the effect of the surger. Involed respectively in T10 in 2,T11 in 5,T12 in 20,L1 in 16,L2 in 1,L3 in 3,L4 in 4 and L5 in 1 vertebrae.Results:The surgical cases in this group are to be successful, two case of patients with anterior bone cement leakage, one cases of patients with disc leakage, but all have no neurological symptoms. No symptomatic complications were found. One case of women L1 vertebral fractures in patients with severe surgical puncture needle piercing due process within the pedicle wall, consider spinal cord injury, had transient lower limb pain and discomfort after surgery for observation, after the symptomatic treatment symptoms.The mean visual ache simulation(VAS) score before surgery was 8.0±1.3 points, after surgery 2.1±0.8 points, preoperative vertebral body height significantly more recovered. The average preoperative vertebral body height of the front 14.5±2.2mm. After surgery an average height of vertebral body front 21.5±2.1mm, the average preoperative vertebral body height of the middle 17.2±2.1mm, after surgery an averageheight of vertebral body posterior 22.4±2.3mm. The mean kyphosis corrected from (25.50±3.50)°to (8.90±4.20)°. No significant loss of vertebrae height and all the patients were available during the follow—up of 6 months(2-18 months).Conclusion:The PKP technique has the advantages of little hurt, and short operation time. It can relieve the pain rapidly and effectively, and can recover the height of sick vertebrae effectively and correct the kyphosis. Thus has a commendable clinic applicative value.
