Kyphoplasty for XXXX : 1-year clinical outcomes from a prospective study.

@entity1 @entity583 @entity16 @entity3814 @entity158 @entity717
OBJECT: Over the past 15 years, vertebroplasty has emerged as a treatment for @entity3814 . This technique, however, does not restore vertebral height and is associated with a high rate of cement leakage. Recently, kyphoplasty was developed in an effort to circumvent this problem. Although its immediate results have been reported, it is unclear whether the benefits endure. METHODS: Seventy-eight consecutive @entity1 underwent 188 kyphoplasty procedures. The @entity1 responded to Short Form-36 (SF-36) questionnaires, a visual analog scale (VAS) for @entity158 rating, and the @entity717 index (ODI) instrument; additionally they underwent detailed neurological and radiographic examinations pre- and postoperatively. The preoperative SF-36, VAS, and ODI scores, the neurological examination results, and the radiographic data were compared with the postoperative findings. Thirteen @entity1 died of disease progression or unrelated illness. Of the surviving @entity1 , complete data were available in 62% (minimum follow-up period 12 months, mean 18 months). Complications included one @entity583 and five cases of asymptomatic cement extravasation. No case of @entity16 occurred during the follow-up period. Significant improvements in seven measures of the SF-36 inventory as well as on the ODI and VAS were noted early postoperatively, and these persisted throughout the follow-up period, despite a statistically insignificant decline in the measure of general health at last follow-up examination. CONCLUSIONS: Kyphoplasty is an effective treatment for @entity3814 . The benefits presented in the early postoperative period and persisted at 1 year posttreatment.
