摘要:

目的 比较斜外侧椎间融合联合侧板固定(OLIF combined with lateral plate fixation,OLIF⁃LP 和联合后路双侧椎弓根钉棒固定(OLIF combined with posterior bilateral pedicle screw fixation,OLIF⁃BPS)治疗单节段腰椎退变性疾病的临床疗效。方法 选择 2020 5 月至 2021 3 月因单节段腰椎退变性疾病 在我院行腰椎减压融合术 64 例,根据固定方式不同分为 OLIF⁃LP 28 例,OLIF⁃BPS 36 例,记录两组患 者的手术时间、出血量、血清肌酸激酶(creatine kinase,CK)、平均住院日和并发症发生情况。通过腰痛和腿痛 VAS 评分、Oswestry 功能障碍指数(ODI)评估临床疗效、通过影像学测量不同时间点椎间隙高度(disk height,DH)、椎管面积(cross⁃sectional area,CSA)和腰椎前凸角(lumbar lordosis,LL)变化并评估椎间融合 情况。结果 OLIF⁃LP 组手术时间(79.61 ± 14.11)min 和术中出血量(64.86 ± 15.01)mL 均低于 OLIF⁃BPS 108.61 ± 20.69)min 和(99.58 ± 22.28)mL,术后 1 d 7 d CK 含量也明显低于同期对照组(均 P < 0.05), 两组术后腰、腿痛 VAS 评分和 ODI 均较术前明显降低,OLIF⁃LP 组术后 7 d 腰痛 VAS 评分低于 OLIF⁃BPS P = 0.04),末次随访时两组比较差异无统计学意义(P = 0.43)。术后各时间点的 DH、LL、CSA 均较术前 有显著性改善(均 P < 0.001),组间比较差异均无统计学意义(均 P > 0.05)。术后半年两组融合率相当 89.29% vs. 91.67%,P = 0.75)。OLIF⁃LP 组和 OLIF⁃BPS 组分别有 5 例(17.86%)和 7 例(19.44%)出现并发 症,发生率比较差异无统计学意义(P = 0.87)。根据沉降标准,OLIF⁃LP 组沉降率 21.43%(6/28),OLIF⁃BPS 组沉降率 19.44%(7/36),沉降病例均未产生临床症状,动态随访中。结论 在严格把握手术适应证的前 提下,OLIF⁃LP 能够达到和OLIF⁃BPS 相似的治疗效果,且手术创伤更小,术后疼痛更轻。

Abstract:

Objective The aim of this study was to compare the clinical effects of oblique lumbar inter⁃ body fusion(OLIF)combined with lateral plate fixation(OLIF ⁃ LP)or posterior bilateral pedicle screw fixation (OLIF⁃BPS)in the treatment of single⁃segment lumbar degenerative diseases(LDD). Methods A total of 64 patients with single ⁃ segment LDD who received lumbar decompression and fusion surgery in our hospital from May 2020 to March 2021 were selected. The patients were divided into OLIF⁃LP group(28 cases)and OLIF⁃BPS (36 cases)according to the surgical methods. The operation time,intraoperative bleeding volume,creatine kinase (CK),average hospitalization days and complications of patients in both groups were recorded. VAS for lumbar and leg pain and ODI scores were used to compare the clinical efficacy of the two groups. Disk height(DH),Cross⁃ sectional area(CSA)and lumbar lordosis(LL)were measured at different time points by imaging,and the inter⁃ body fusion was evaluated. Results The operation time(79.61 ± 14.11)min,the intraoperative bleeding volume (64.86 ± 15.01)mL in OLIF⁃LP group were less than those in OLIF⁃BPS group(108.61 ± 20.69)min,(99.58 ± 22.28)mL. The CK at 1 and 7 days postoperation were significantly lower in OLIF⁃LP group than those in OLIF⁃ BPS group(P < 0.05). The VAS score and ODI of low back pain in both groups were significantly lower than thosepreoperation. The VAS score of low back pain in OLIF ⁃ LP group was significantly lower than that in OLIF ⁃BPS group at 7 days postoperation(P = 0.04),but there was no significant difference between the two groups at the last follow⁃up(P = 0.43). DH,LL and CSA at each time point postoperation were significantly improved as compared with those preoperation(P < 0.001),there was no significant difference between the two groups(P > 0.05). At half a year postoperation,the fusion rate was comparable(89.29% vs. 91.67%,P = 0.75). Complications occurred in 5 cases(17.86%)and 7 cases(19.44%)in OLIF⁃LP group and OLIF⁃BPS group respectively,and the incidence was not statistically significant(P = 0.87). According to the subsidence criteria,the subsidence rate of OLIF⁃LP group was 21.43%(6/28),and that of OLIF⁃BPS group was 19.44%(7/36). Without symptom in all subsidence cases. Conclusions Under the premise of strictly grasping the surgical indications,OLIF ⁃LP technique could obtain comparable effective outcomes as OLIF⁃BPS surgery for the treatment of LDD,and patients with OLIF⁃LP have less trauma,less pain after surgery.
