Comparison of clinical efficacies among three surgical methods in treating stage Ⅲ Kümmell disease without neurological symptoms
Objective To compare the clinical efficacies among three surgical methods in the treatment of stage Ⅲ Kümmell's disease without neurological symptoms.Methods A total of 71 patients with stage Ⅲ Kümmell's disease without neurological symptoms admitted and treated in the orthopedics department of Af-filiated Yueyang Hospital of Hunan Normal University from September 2019 to April 2022 were selected and divided into three groups:29 cases in the percutaneous vertebroplasty (PVP) group (group A),19 cases in the percutaneous pedicle screw+lesioned vertebral PVP group (group B) and 21 cases in the percutaneous bone cement screw combined with lesioned vertebral PVP group (group C) according to the operation methods.The imaging,perioperative and follow-up indexes were compared among the three groups.Results All patients successfully completed the operation,no serious complications occurred after operation,and the follow-up time was more than 1 year.The sagittal position index (SI value) in the affected vertebra,visual analogue scale (VAS) score and Oswestry Disability Index (ODI) score at each time point (postoperative 1,3 months,1 year) after surgery in the group A were improved compared with before operation (P<0.05).The affected vertebra SI value,kyphosis Cobb angle,spinal canal stenosis rate,VAS score and ODI score at postoperative time points in the group B and C were improved compared with before operation (P<0.05).The affected ver-tebra SI value,kyphosis Cobb angle,spinal canal stenosis rate and ODI score at postoperative time points in the group B and C all were superior to those in the group A (P<0.05),while the affected vertebra SI value,kyphosis Cobb angle and spinal canal stenosis rate in postoperative 1 year in the group C were superior to those in the group B (P<0.05).The operative time,intraoperative bleeding volume,postoperative hospitaliza-tion duration and affected vertebral cement injection volume in the group A were significantly less than those in the group B and C (P<0.05).The operation time in the group B was less than that in the group C (P<0.05).Conclusion The three surgical methods for the treatment of stage Ⅲ Kümmell's disease without neu-rological symptoms all could relieve the symptoms and restore the function.The two surgical methods of pedi-cle screw reduction could more effectively restore the height of the affected vertebra,correct kyphosis malfor-mation and improve spinal stenosis than PVP alone.The pedicle screw has more advantages in maintaining mechanical support and stability after bone cement reinforcement.
