    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 < 0.001), and lower leakage rates (p < 0.05), with primarily chunky cement distributions versus mixed distributions in the PVP group. No complications other than cement leakage occurred. VAS and ODI scores showed no significant changes at various time points (p > 0.05) but improved significantly from preoperative (p < 0.001). Both groups saw improved vertebral heights and Cobb angles post-surgery (p < 0.05), with more significant improvements in the PKP group (p < 0.05). Over time, both groups experienced gradual vertebral height loss and increased Cobb angles, more pronounced in the PKP group (p < 0.05). At the final follow-up, there were no statistical differences in vertebral height and Cobb angle between the two groups (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.
