文题释义:
轻度退行性侧弯:冠状面畸形Cobb角位于10°-30°的脊柱退行性侧弯畸形称为轻度退行性侧弯。此类患者通常因腰椎管狭窄症致间歇性跛行就诊,腰部症状可能不明显。
长、短节段固定:轻度退行性侧弯的固定节段长短没有定论。长短节段没有统一标准,但一般而言,长节段固定一般是指固定范围达到或超过上、下端椎,短节段固定是指固定范围未达到上、下端椎。
 
摘要
背景:临床上常见伴有轻度退行性侧弯的腰椎管狭窄患者,但是对于手术固定范围存在争议。
目的:针对伴有退行性侧弯的腰椎管狭窄患者,对长节段固定和短节段固定后的影像及临床疗效进行对比分析。
方法:94例患者纳入历史性队列研究,纳入标准为伴有冠状面10°-30°退行性侧弯的腰椎管狭窄症,主要症状包括腰痛、下肢无力或间歇性跛行。根据固定节段长短,分为2组,长节段组46例,短节段组48例。所有患者对治疗方案均知情同意,且得到医院伦理委员会批准。功能评分考察目测类比评分、Oswestry功能障碍指数、Roland Morris指数和日本骨科学会评分。另外考察患者的年龄、手术时间、出血量、固定节段和侧弯Cobb角。
结果与结论:①长节段组较短节段组固定长度大约多1个椎体(P < 0.01);虽然长节段组手术时间、出血量均大于短节段组,但差异无显著性意义(P > 0.05);②短节段组Cobb角手术前后差异无显著性意义(t=0.885,P=0.388),而长节段组Cobb角由术前(16.5±4.7)°矫正至末次随访的(9.2±6.2)°(t=7.095,P < 0.001);③无论短节段组或是长节段组,患者的术后Oswestry功能障碍指数、Roland Morris指数、目测类比评分、日本骨科学会评分均较术前显著改善(P均≤0.005),说明无论何种行何种术式,术后患者的生活质量均有明显提高,2组之间差异均无显著性意义(P > 0.05);另外就Oswestry功能障碍指数和日本骨科学会评分问卷中的各个问题进行逐项分析,发现与短节段组相比,长节段组术后在“行走功能”方面有一定改善(P < 0.05);④总体来看末次随访长节段组患者满意度较高,但2组间各项问题差异均无显著性意义(P > 0.05);⑤提示轻度退行性侧弯的腰椎管狭窄症患者行长、短节段固定后功能和满意度方面均无明显差异,疗效相当。

Abstract:

BACKGROUND: Lumbar mild degenerative scoliosis with stenosis is a common disease; however, there is still controversy regarding to the surgical fixation range.

OBJECTIVE: To comparatively analyze the imaging and clinical effects of full curve fusion and limited fusion in patients with lumbar spinal stenosis accompanied by degenerative scoliosis.
METHODS: The historical cohort study consisted of 94 patients. Inclusion criteria were: degenerative scoliosis with Cobb’s angle over 10 degrees and not above 30 degrees. The main symptoms included low back pain, weakness of lower limbs or claudication. According to the length of fixed segments, they were divided into two groups: full curve fusion group (46 cases) and limited fusion group (48 cases). All patients signed the informed consent. This study was approved by the Hospital Ethics Committee. Visual Analog Score of pain, Oswestry Disability Index, Roland Morris Scores and Japanese Orthopaedic Association Scores were assessed. Patient data including age, operation time, blood loss, length of instrumented segments, and Cobb angle were also analyzed.
RESULTS AND CONCLUSION: (1) The full curve fusion group had 1 more vertebra instrumented than the limited fusion group (P < 0.01). Although the operation time and bleeding volume of the full curve fusion group were greater than those of the limited fusion group, there was no significant difference (P > 0.05). (2) There was no significant difference in Cobb angle in the limited fusion group before and after operation (t=0.885, P=0.388). Cobb angle in the full curve fusion group was corrected from preoperatively (16.5±4.7) degrees to the final follow-up (9.2±6.2) degrees (t=7.095, P < 0.001). (3) Visual Analog Score of pain, Oswestry Disability Index, Roland Morris Scores and Japanese Orthopaedic Association Scores were significantly improved postoperatively compared with those preoperatively in both full curve fusion and limited fusion groups (all P ≤ 0.005). These indicated that the quality of life of patients after operation was significantly improved regardless of the type of surgery. There was no significant difference between the two groups (P > 0.05). In addition, the analysis of items of Oswestry Disability Index and Japanese Orthopaedic Association Scores found that compared with the limited fusion group, the walking ability was improved in the limited fusion group (P < 0.05). (4) Overall, the patients in the full curve fusion group had higher satisfaction at the final follow-up, but there was no significant difference in the problems between the two groups (P > 0.05). (5) It is suggested that there is no significant difference in the function and satisfaction of patients with lumbar spinal stenosis with mild degenerative scoliosis after full curve fusion and limited fusion, and the efficacy was comparable.
