  • Effectiveness comparison between two operations in treatment of unstable type Kümmell’s disease

    Objective To compare the effectiveness between short segmental fixation combined with vertebroplasty (SSF+VP) and short segmental pedicle screw fixation combined with bone graft (SSF+BG) in the treatment of unstable type Kümmell’s disease so as to provide a reference for the selection of the surgical method. Methods Between March 2013 and February 2015, 48 patients with unstable type Kümmell’s disease who were in accordance with the inclusive criteria were included in the study. SSF+VP were used in 25 cases (SSF+VP group) and SSF+BG in 23 cases (SSF+BG group). There was no significant difference in gender, age, disease duration, bone mineral density, fracture segment, and preoperative visual analogue scale (VAS), Oswestry disability index (ODI), and kyphotic Cobb angle between 2 groups (P>0.05). The operation time and complications related to operation were recorded; the effectiveness was evaluated by VAS, ODI, and kyphotic Cobb angle. Results The operation time was (107.7±18.8) minutes in SSF+VP group and was (113.7±22.4) minutes in SSF+BG group, showing no significant difference between 2 groups (t=–1.045,P=0.302). Bone cement leakage occurred in 6 cases of SSF+VP group, and incision delayed healing occurred in 1 case of SSF+BG group. All patients achieved bone graft fusion on X-ray films. The bone graft fusion time was (15.1±1.3) weeks in SSF+VP group and (15.7±1.8) weeks in SSF+BG group, showing no significant difference between 2 groups (t=–1.361,P=0.180). The VAS, ODI, and kyphotic Cobb angle at immediate after operation and at last follow-up were significantly lower than preoperative ones (P<0.05). The VAS, ODI, and kyphotic Cobb angle had no significant difference between at immediate and at last follow-up in SSF+VP group (P>0.05). In SSF+BG group, VAS at last follow-up was significantly lower than that at immediate after operation (P<0.05), but no significant difference was found in kyphotic Cobb angle and ODI (P>0.05). SSF+VP group was significantly better than SSF+BG group in VAS at immediate after operation (P<0.05), but SSF+BG group was significantly better than SSF+VP group at last follow-up (P<0.05). There was no significant difference in kyphotic Cobb angle and ODI between 2 groups at immediate after operation and at last follow-up (P>0.05). Conclusion SSF+BG can achieve satisfactory effectiveness in the treatment of unstable type Kümmell’s disease, and it has the advantages of good bony healing, obvious improvement of pain, and low complication incidence when compared with SSF+VP.
