- Abstract:
- Abstract: Objective To investigate the efficacy of microsurgical decompression through paraspinal approach using percutaneous tubular retractor system on the isolated thoracic ossification of ligamentum flavum (OLF). Methods The clinical data of 120 cases of microsurgical decompression through paraspinal approach using percutaneous tubular retractor system for the isolated thoracic OLF were retrospectively analyzed. The operation time, hospital stay, intraoperative blood loss and overall efficacy were recorded. Moreover, Japanese orthopaedic association score, pain visual analogue score and creatine phosphokinase activity before and after surgery were analyzed. According to the efficacy, the patients were divided into poor efficacy group and excellent efficacy group. The clinical data of the two groups were compared, so as to analyze the factors that might affect the therapeutic effects. Results The operation time, intraoperative blood loss and hospital stay were (94.36±10.25) min, (38.12±4.63) mL and (7.68±0.82) d, respectively. Japanese orthopaedic association score at 6 months after surgery was significantly higher than that before surgery (P<0.05), while pain visual analogue score was significantly lower than that before surgery (P<0.05). There was no significant difference in creatine phosphokinase activity before surgery and 5 days after surgery (P>0.05). The course of disease in excellent efficacy group was significantly shorter than that in poor efficacy group (P<0.05), and the mean age was significantly lower than that in poor efficacy group (P<0.05). Moreover, the proportion of the upper and middle thoracic vertebrae in the surgical segment and the residual rate of spinal canal area were significantly higher in excellent efficacy group than in poor efficacy group (P<0.05). The advanced age, long course of disease, thoracolumbar segment of the surgical segment and the low residual rate of the spinal canal area were the independent risk factors affecting therapeutic effects (P<0.05). Conclusion The microsurgical decompression through paraspinal approach using percutaneous tubular retractor system has a significant therapeutic effect on the isolated thoracic OLF. The advanced age, long course of disease, thoracolumbar segment of the surgical segment and the low residual rate of the spinal canal area are considered as the independent risk factors.
