Bottom Line: However, preoperative compression rate in the RA group was significantly (p=0.025) higher compared to that in the control group.Although higher incidence of recollapse occurred in the RA group compared to that in the control group, the difference was not statistically significant (p=0.305).Higher incidence of recollapse occurred in the RA group compared to that in the control group, although it was not statistically significant.

ABSTRACT

Study design: Retrospective study.

Purpose: This study was conducted to compare vertebral body height restoration rate in rheumatoid arthritis (RA) patients who had undergone percutaneous balloon kyphoplasty (KP) with that of control group who had matched age, sex, body mass index, and bone mineral density.

Overview of literature: There is no report on result of KP in RA patients.

Methods: Postoperative height restoration rate of RA group consisting of 15 patients (18 vertebral bodies) who had undergone KP due to osteoporotic vertebral compression fracture with a 30% or higher vertebral compression rate between May 2005 and January 2013 were compared to control group consisting of 38 patients (39 vertebral bodies) who had matched age, sex, body mass index, and bone mineral density.

Results: No statically significant difference in age (p=0.846), sex (p=0.366), body mass index (p=0.826), bone mineral density (p=0.349), time to surgery (p=0.528), polymethylmethacrylate injection time (p=0.298), or amount (p=0.830) was found between the RA group and the control group. However, preoperative compression rate in the RA group was significantly (p=0.025) higher compared to that in the control group. In addition, postoperative height restoration rate showed significant correlation with the RA group (p=0.008). Although higher incidence of recollapse occurred in the RA group compared to that in the control group, the difference was not statistically significant (p=0.305).

Conclusions: Compared to the control group, RA patients showed higher compression rate and higher vertebral restoration rate after KP, indirectly indicating weaker bone quality in patients with RA. Higher incidence of recollapse occurred in the RA group compared to that in the control group, although it was not statistically significant.

(A) The preoperative compression rate was calculated as the percentile of the height of the compressed anterior vertebral body against the mean height of adjacent top and bottom vertebral bodies in the lateral radiographs. (B) The postoperative restoration rate was determined in the same manner as that prior to surgery.

Figure 2: (A) The preoperative compression rate was calculated as the percentile of the height of the compressed anterior vertebral body against the mean height of adjacent top and bottom vertebral bodies in the lateral radiographs. (B) The postoperative restoration rate was determined in the same manner as that prior to surgery.

Mentions: Preoperative compression rate was calculated as percentile of the height of the compressed anterior or middle vertebral body against the mean height of the anterior or middle vertebral bodies of adjacent top and bottom vertebral bodies in lateral radiographs taken in supine position (Fig. 2). Postoperative restoration rate was calculated using a method described by McKiernan et al. [7] based on the values of the anterior or intermediate vertebral bodies in the standing lateral radiograph determined in the same manner as that prior to surgery (Fig. 2). The recollapse of cemented vertebra was diagnosed as recurrent back pain. It was postoperatively correlated with height reduction of cemented vertebra and osteolysis around the cement on serial standing lateral radiograph. Bone mineral density was measured with dual energy X-ray absorptiometry.
