摘要:

背景:下肢的不等长影响肢体保肢治疗的效果。即便通过透视监测,在手术中确保肢体等长,仍是一个难以把握的问题,尤其是对于髋臼区域恶性肿瘤的保肢治疗。在骨科的其他方面,如脊柱和关节,导航技术已经较多应用于内固定器械安置和假体放置。
目的:回顾分析在计算机导航系统指导下髋臼区恶性肿瘤保肢治疗的效果。
方法:选择2001-01/2009-06上海瑞金医院骨科收治的11例骨盆恶性骨肿瘤患者,术前经病理确诊,肿瘤切除后应用定制型假体重建。其中8例患者进行常规保肢手术,另外3例患者行计算机导航技术辅助保肢治疗。所有患者骨盆恶性肿瘤的切除范围位于髋臼周围区(骨盆Ⅱ区)。患者保肢治疗后予以临床、影像学检查,并行下肢保肢功能MSTS评分。
结果与结论:随访12~60个月。经常规保肢治疗的8例患者,平均手术时间7.6 h,平均失血量2 400 mL,1例患者因肺部转移而在术后3年死亡,1例患者因局部复发行截肢术。除去这2例患者,保肢治疗后有3例患者髋臼假体的移位超过2 cm而形成下肢不等长。MSTS评分平均20.3分。在计算机导航技术辅助下保肢治疗的3例患者,平均手术时间8.3 h,平均失血量2 100 mL,保肢治疗后未见下肢不等长现象。MSTS评分平均21.7分。提示在计算机导航系统指导下进行髋臼区恶性肿瘤保肢手术,可以精确截骨,准确安放假体,减少髋臼区恶性肿瘤保肢治疗后下肢不等长发生率,提高患肢功能。

Abstract:

BACKGROUND: Limb length discrepancy (LLD) influences the effect of limb-salvage treatment. Although through perspective of monitoring to ensure limbs isometry during operation, it is still a difficult problem to grasp, especially for limb-salvage treatment of malignant tumors in acetabular region. In other aspects of orthopedics, such as spinal column and joint, navigation technology has been more used to the installation of internal fixation and prosthetic placement.
OBJECTIVE: To retrospectively analyze the effect of limb-salvage treatment of malignant tumors in acetabular region under the computer-assisted navigation system.
METHODS: From January 2001 to June 2009, a total of 11 malignant pelvic bone tumors cases received treatment at the Department of Orthopedics, Shanghai Ruijin Hospital were selected. They underwent preoperative pathological diagnosis; custom-made prosthesis reconstruction was applied after tumor resection, including 8 cases underwent normal limb salvage surgery; the remaining 3 cases were treated with computer-assisted navigation limb salvage. The pelvic malignancies resection scopes of all patients were located in acetabular surrounding region (pelvic areaⅡ). Patients were examined clinically and radiographically after the treatment of limb salvage, and were assessed by lower extremity limb salvage function musculoskeletal tumor society (MSTS) score.
RESULTS AND CONCLUSION: In 12-16 months follow-up, 8 cases with normal limb salvage, the mean operation time-consuming was 7.6 hours, and the mean volume of blood loss was 2 400 mL. One case was died of lung metastasis at 3 years after surgery, one case suffered from amputation because of local recurrence. In addition to these two patients, the deviation of acetabular prosthesis exceeded 2 cm to form LLD in 3 cases after the treatment of limb salvage. The mean MSTS score was 20.3 points. Among the 3 cases treated with computer-assisted navigation limb salvage, the mean operation time-consuming was 8.3 hours, and the mean volume of blood loss was 2 100 mL. No cases represented LLD. The mean MSTS score was 21.7 points. It is indicated that limb-salvage treatment of malignant tumors in the acetabular region under the computer-assisted navigation system can cut bone precisely, place prosthesis accurately, reduce the incidence rate of LLD in the acetabular region after the treatment of limb salvage, and improve affected limb function.
