Summary
This can be a retrospective case-control research.The goal of this research was to match the surgical outcomes of percutaneous kyphoplasty (KP) and posterior spinal fixation with vertebroplasty (PSF+VP) for therapy of Kümmell illness (KD).KD is uncommon type of post-traumatic delayed avascular necrosis of the vertebral physique. It’s reported that KP is an impact measure for therapy of KD. Some research have beneficial posterior spinal fixation with vertebroplasty for KD.A complete of 100 sufferers with KD who underwent spinal surgical procedure at our hospital have been enrolled from January 2008 to December 2013. The inclusion standards have been monosegment lesion with out neurological deficit; the segments are restricted to T11-L2; conservative therapy is invalid. The exclusion standards have been metastatic spinal tumors, an infection, major bone tumor, and a number of myeloma; bisegments and multi-segments; sufferers with neurological signs; the defect of posterior wall of vertebral physique; the occupying of vertebral canal. The symptomatic vertebrae have been restricted to T11-L2. Sufferers who have been followed-up for lower than 2 years after surgical procedure have been excluded. Lastly, there are 25 sufferers within the KP group and 21 within the PSF+VP group. There have been no important variations in affected person age, illness period, or the size of follow-up between the two teams.Operative time (43.2?±?21.eight vs 230.6?±?87.1?minutes) was considerably longer and bleeding quantity (5.three?±?three.1 vs 215.zero?±?170.2?mL) considerably better within the PSF+VP group. No important distinction between the two teams was noticed in Visible analog scale rating (VAS) (1.three?±?zero.9 vs 1.2?±?zero.9), Oswestry incapacity index rating (ODI) (27.2?±?9.zero vs 26.zero?±?6.three), and Cobb angle (17.zero?±?7.2 vs 16.5?±?2.eight). KP resulted in a shorter operation time, much less bleeding quantity, and fewer postoperative problems than PSF+VP.This research reveals that each remedies KP and PSF+VP for KD might be secure and efficient for the sufferers with monosegment lesion and with out neurological deficit. Nevertheless, KP present the benefits in a shorter surgical period, much less blood loss, and fewer postoperative problems.
