Abstract:
Objective:To investigate the effect of thoracolumbar osteoporotic vertebral compression fracture (OVCF) combined with lumbar degenerative spondylolisthesis (LDS) on spinopelvic sagittal parameters in the elderly.Methods:A case-control study was conducted to analyze the clinical data of 77 patients with thoracolumbar OVCF admitted to Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from December 2016 to December 2021. There were 16 males and 61 females with the age of 61-92 years [(73.9±8.4)years]. All patients had single-level thoracolumbar fractures (T 11-L 2). Simple thoracolumbar OVCF was found in 49 patients (OVCF group) and thoracolumbar OVCF combined with LDS in 28 (OVCF+LDS group). The pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), sagittal vertical axis (SVA) and Roussouly types were detected and compared between the two groups before operation. Results:There was no significant difference in PT and SVA between the two groups (all P>0.05). The PI, SS, LL, TK and TLK in OVCF+LDS group were (55.8±11.0)°, (34.1±10.9)°, (45.7±9.1)°, (35.7±6.1)° and (24.8±5.2)°, significantly larger than (47.9±8.8)°, (27.0±9.4)°, (33.1±7.9)°, (29.5±6.2)° and (18.4±5.5)° in OVCF group (all P<0.01). Roussouly types I-IV counted 22, 16, 5 and 6 patients in OVCF group, compared to 8, 5, 6 and 9 patients in OVCF+LDS group ( P<0.05). Conclusions:Elderly patients with thoracolumbar OVCF combined with LDS can significantly alter spinopelvic sagittal parameters, and LDS may aggravate the thoracolumbar kyphosis of OVCF. To avoid sagittal imbalance, surgery should be performed as soon as possible.
