Abstract:
Objective:To explore the differences in clinical and injured vertebra radiological parameters between patients with non-traumatic osteoporotic vertebral compression fracture (OVCF) and those with traumatic OVCF after percutaneous vertebroplasty (PVP).Methods:A retrospective study was conducted to analyze the 369 OVCF patients (with 458 vertebrae injured) who had been treated by PVP at Department of Orthopaedics, Beijing Luhe Hospital between October 2015 and March 2017. There were 292 females and 77 males with a mean age of 73 (60, 79) years. Based on the absence or presence of a trauma history, the patients were stratified into a non-traumatic group (127 patients with 160 vertebrae injured) and a traumatic group (242 patients with 298 vertebrae injured). Clinical parameters [age, gender, body mass index, symptomatic duration, and number of injured vertebrae, visual analogue scale (VAS), Oswestry disability index (ODI), duration of follow-up, and rate of new OVCFs] and injured vertebra radiological parameters (position of injured vertebra, fracture type, compression severity, fracture range, cortical defect, intravertebral cleft, spinal canal compromise, basivertebral foramen, morphology of bone cement, range of bone cement, cement leakage, cement volume, rate of vertebral height restoration, recollapse of cemented vertebrae) were recorded perioperatively. All the clinical and radiological parameters were compared between the 2 groups.Results:Compared with the traumatic group, the non-traumatic group had an older age [75 (71, 83) years versus 71 (65, 76) years], more females (85.0% versus 76.0%), a longer symptomatic duration [10.0 (7.0, 15.0) d versus 6.5 (2.0, 12.0) d], a lower preoperative VAS pain score [7 (6, 8) points versus 7 (7, 8) points], a lower VAS pain score at postoperative day 1 [2 (2, 3) points versus 2 (2, 3) points], a lower preoperative ODI [66% (63%, 72%) versus 70% (65%, 73 %)], a lower ODI at postoperative day 1 [32% (30%, 34%) versus 32% (31%, 34%)], a higher rate of new OVCFs during follow-up (34.6% versus 12.8%), a lower rate of thoracolumbar lesions (51.9% versus 70.1%), more deformed fractures (mostly amphicoelous type), a lower rate of cortical defects in the anterior wall (20.0% versus 31.5%), a higher rate of trabecular pattern of cement (83.1% versus 71.8%), a higher rate of type-B cement leakage (50.6% versus 31.9%), a lower rate of type-C cement leakage (5.6% versus 12.8%), a lower rate of recollapse of cemented vertebrae (43.8% versus 55.4%). All the comparisons above were statistically significant ( P<0.05). There were no significant differences between the 2 groups in the other clinical or radiological parameters ( P>0.05). Conclusions:There are statistically significant differences in a significant number of clinical and injured vertebra radiological parameters between patients with non-traumatic OVCF and those with traumatic OVCF after PVP. It is noteworthy that non-traumatic OVCFs are one specific subgroup of OVCFs.
