Lu W, Wang L, Xie C, et al. - Three retrospective case-control studies were involved to assess the efficiency of percutaneous kyphoplasty (PKP) and short segment internal fixation combined with vertebroplasty (SSF + VP), to give evidence-based medical support for the decision-making process when treating Kummell disease (KD, a delayed vertebral compression fracture characterized by the prevalent features like a history of minor trauma, following which the pain passes, but the symptoms recur or worsen, and a kyphosis deformity occurs months or years later) patients without neurological deficits. The variations in the bleeding volume and operation time were statistically meaningful. The combined data exhibited that the variations in visual analog scale score, Oswestry Disability Index score, local vertebral Cobb angle, and cement leakage were not statistically important. Therefore, in treating KD patients without neurological symptoms, this analysis illustrates that the PKP and SSF + VP methods are safe and efficient. Nevertheless, PKP can reduce operation time and decrease the volume of blood loss.
