Comparative analysis of percutaneous vertebroplasty and kyphoplasty in the treatment of Stage III Kummell’s disease without neurological symptoms: a retrospective study

Abstract

Abstract Objective This study analyzes the safety and efficacy of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) treatments for Stage III Kummell’s disease without neurological symptoms, comparing the advantages and disadvantages of these two minimally invasive surgical methods. Methods A retrospective analysis was conducted on 53 patients with non-neurological Stage III Kummell’s disease treated with PVP and PKP at our hospital from December 2018 to January 2023. Patients were divided into PVP (25 cases) and PKP (28 cases) groups based on the surgical method. There were no significant differences in general preoperative data between the two groups (all p > 0.05), ensuring comparability. The study compared surgical duration, volume of bone cement injected, distribution pattern of bone cement, rate of bone cement leakage, and preoperative, postoperative, and final follow-up scores of Visual analogue scale(VAS) and Oswestry disability index(ODI). Additionally, relative anterior height of the injured vertebrae, and Cobb angle of deformity, along with their changes at preoperative, postoperative, and final follow-up stages were calculated and analyzed. Results No significant preoperative differences were observed between the groups (p > 0.05). The PKP group had longer surgeries, higher cement volumes (p 0.05) but improved significantly from preoperative (p 0.05). Conclusion The study evaluates the safety and efficacy of PVP and PKP for Stage III Kummell’s disease without neurological symptoms, comparing the merits of both minimally invasive techniques.
