The operation time, blood loss, nerve damage, success rate of removal, infection control, and fusion rate were compared between the traditional whole removal method (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200915) and the ultrasonic osteotome\u2010based segmental excision method (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200917).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The average incision length and hospital stay were not significantly different between the two groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&gt;\u20090.05). Nevertheless, the time taken for removing the cage, the success rate of cage removal, intraoperative blood loss, and postoperative drainage were significantly improved in the ultrasonic osteotome group compared with the traditional surgery group (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05). The assessment of postoperative recovery at 7\u2009days and 1, 3, 12\u2009months postoperation demonstrated significant improvements in VAS and ODI scores compared with the preoperative values in both groups. However, within\u2010group and between\u2010group analyses did not reveal significant differences at these intervals, even up to the 12\u2010month evaluation (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&gt;\u20090.05). Contrast\u2010enhanced lumbar MRI scans conducted for the 32 patients at 3\u2009months postoperation confirmed successful infection control among all patients. Both groups demonstrated no incidence of dural tears, cerebrospinal fluid leakages, or wound infection. In contrast, incisional fat liquefaction occurred in one and two patients in the ultrasonic osteotome and traditional surgery group, respectively, with all patients exhibiting satisfactory resolution following appropriate wound care. Moreover, a slight deterioration in the extensor muscle strength of the great toe was observed in two patients and an exacerbation of foot dorsum numbness was detected in one patient in the traditional surgery group, with all symptoms fully resolving within the 3\u2010month follow\u2010up period. In contrast, the ultrasonic osteotome group showed no such significant neurological function impairments. At 1\u2010year postoperation, bone fusion was confirmed in both groups via CT reconstructions of the lumbar spine.\n                    <\/jats:p>\n                  <\/jats:sec>\n
