FU follow-up, M month, Pre preoperative, Post postoperative, FFU final follow-up, CA correction angle, CR correction rate, LA loss angle, LR loss rate
^aThere was no statistically significant difference in the preoperative kyphosis angle or follow-up time between the two groups (P > 0.05)
^bThe kyphosis angles of the two groups were significantly improved after surgery (P < 0.05)
^cThe kyphosis correction angle and rate in group A were greater than those in group B (P < 0.05). The loss rate in group B was greater than that in group A (P < 0.05)
^dThere was no significant difference in the loss angle between group A and group B (P > 0.05)
