This was a retrospective study approved by the Institutional Review Board of The First Affiliated Hospital of Soochow University, and informed consent was obtained from all patients.
Between January 2019 to December 2020, 223 patients (185 females and 38 males) who were diagnosed as single level OVF and treated by PKP surgery in our institution were included in this study. The included patients were classified into two groups according to the presence or absence of fascia injury (With-FI group and Without-FI group). The average age of the patients was 70.35 ± 8.34 years (ranging from 55 to 93 years).
Inclusion criteria: 1) bone marrow edema in the affected vertebra with or without posterior fascia injury in MR images; 2) severe back pain unresponsive to conservative treatment for at least one week; 3) T-scores assessed by Dual Energy X-ray Absorptiometry was less than -2.5.
Exclusion criteria: 1) pathological fracture secondary to infection or malignancy; 2) unable to tolerate the operation; 3) severe OVF presented fracture dislocation; 4) neurological deficit caused by OVF; 5) combined with Alzheimer's disease or other diseases which made the patients unable to finish information collection on their own.
The time interval between fracture and PKP surgery was recorded as fracture age. The OVF related trauma history was evaluated and the severity of trauma was divided into three degrees (none or minor, moderate, and severe). Vertebral fractures caused by coughing, twisting waist, and other daily activities were considered minor trauma. Moderate trauma was defined as stumble, falls from chairs, and other minor accidents caused by definite external forces. Serious trauma was referred to car accidents, falls from high places and other damages caused by severe external forces.
