Comparative Analysis of Long and Short Level Fusion Combined with Posterior Pedicle Screw System in the Treatment of Degenerative Scoliosis
Objective To investigate the application value of long-segment fusion and short-segment fusion combined with posterior pedicle screw system internal fixation in the treatment of degenerative scoliosis.Methods 60 patients with degenerative scoliosis admitted to our hospital from June 2021 to June 2023 were selected as the research objects.According to the random number table method,they were divided into a control group and an observation group,with 30 cases in each group.Both groups were treated with posterior pedicle screw system internal fixation.The control group was treated with short segment fusion,and the observation group with long segment fusion.After 3 months of follow-up,the operation,imaging parameters,pain score,Oswsetry Disability Index(ODI)score,and quality of life were compared between the two groups.Results The operation time of the observation group was(232.41±28.68)min,which was longer than(164.85±14.83)min of the control group.The intraoperative blood loss,postoperative drainage,and intraoperative fluoroscopy times were(554.96±52.41)mL,(156.32±14.82)mL,and(6.32±1.15)times,respectively.Compared with the control group(449.65±45.84)mL,(123.41±13.35)mL and(4.21±0.83)times,the differences between the two groups were statistically significant(P＜0.05).The postoperative Cobb Angle,Sagittal balance offset and coronal balance offsct of the observation group were(18.15±1.63)°,(17.79±1.45)mm and(13.51±1.23)mm,respectively,which were lower than(22.34±2.49)°,(23.53±2.57)mm and(16.78±1.45)mm of the control group.The difference between the two groups was statistically significant(P＜0.05).The postoperative Visual Analog Scale of Pain score and ODI score of the observation group were(1.42±0.24)points and(12.58±1.23)points,respectively,which were lower than(1.98±0.27)points and(15.39±1.42)points of the control group,the differences between the two groups were statistically significant(P＜0.05).The scores of quality of life in the observation group were(87.25±5.24)points,(88.26±5.19)points,(88.93±5.25)points and(90.76±4.15)points,respectively.The scores were higher than(80.62±5.21)points,(81.11±5.09)points,(82.04±5.18)points,(83.63±4.58)points of the control group,the differences between the two groups were statistically significant(P＜0.05).Conclusion Both long-segment and short-segment fusion are valuable in the treatment of degenerative scoliosis.Short-segment fusion is less invasive,while long-segment fusion can better restore spinal alignment and function,which should be carefully selected according to the clinical characteristics.
