Efficacy of Computed Tomography-assisted Limited Decompression in the Surgical Management of Thoracolumbar Fractures With Neurological Deficit

Abstract

Objective: to investigate the effect of CT-assisted limited decompression in the management of single segment A3 lumbar burst fracture. Method: A retrospective study of 106 cases with a single-level Magerl type A3 lumbar burst fractures treated with short-segment posterior internal fixation and limited decompression from January 2015 to June 2019 was performed. Patients were divided into two groups: CT-assisted and non-CT-assisted. Perioperative factors, clinical outcomes, postoperative complications, imaging parameters and health-related quality of life (HRQoL) were evaluated. Results: There was no significant difference between the two groups in the kyphosis, anterior vertebral body height loss, posterior vertebral body height loss, operative time, and postoperative complications. The visual analogue score (VAS) and spinal canal encroachment in the CT-assisted group were lower than those in the non-CT-assisted group (P < 0.05). The Japanese Orthopaedic Association score (JOA), the simplified HRQoL scale and American Spinal Injury Association (ASIA) Spinal Cord Injury Grade in the CT-assisted group were higher than those in the non-CT-assisted group (P < 0.05).Conclusion: CT-assisted limited decompression in the treatment of single-segment A3 lumbar burst fracture can achieve better fracture reduction and surgical results, and improve the long-term recovery of neurological function and quality of life of the patients.

Prognostic value of pretreatment anemia in patients with soft tissue sarcoma

“…The effect of hypoxia on different subtypes is inherently heterogeneous. Nakamura et al found that pretreatment anemia was not associated with the prognosis of liposarcoma, while malignant fibrous histiocytoma was the opposite [23,42] . Patients may differ from study to study, so heterogeneity is acceptable.…”

[23,42] Patients may differ from study to study, so heterogeneity is acceptable. Second, the cutoff values between different studies are different.…”
