这是CHARITE（TM）人工椎间盘临床和影像学结果的首次报告，随访时间至少为10年。共有107例患者接受了全腰椎间盘置换术，植入了CHARITE（TM）假体。在这107名患者中，有100名接受了至少10年的随访（范围10-13.4年）。共植入147个假体，其中单节段54个，双节段45个，三节段1个。通过标准的前腹膜后入路放置假体。在临床上，62%的患者结局极佳，28%的患者结局良好，10%的患者结局较差。在95名有资格重返工作岗位的患者中，88人（91.5%）要么回到手术前的同一工作岗位，要么换了一份工作。其中包括63.2%（12）从事繁重劳动的人重返同一工作。所有节段的平均屈曲/伸展运动为10.3度（L3-L4为12.0度，L4-L5为9.6度，L5-S1为9.2度）。平均侧向运动为5.4度。在矢状面上，9例（6.1%）位于几何中心前方，50例（34.0%）位于几何中心后方，88例（59.9%）位于几何中心后方。在额状面，110例（75%）位于中心，37例（25%）位于中心外侧。在2名患者中观察到轻微下沉，但他们不需要进一步手术。未发现假体半脱位和自发性关节融合病例。有1例椎间盘高度丢失1 mm。5例患者需要二次后路关节融合术。良好或极佳的临床结局率为90%，恢复工作率为91.5%，与文献中描述的用于治疗腰椎退行性椎间盘疾病的融合结果相比具有优势。在至少10年的随访中，CHARITE（TM）人工椎间盘表现出极好的屈曲/伸展和侧向活动范围，没有明显的并发症。
This is the first report of clinical and radiologic outcomes for the CHARITE (TM) artificial disc with a minimum follow-up of 10 years. A total of 107 patients indicated for total lumbar disc replacement were implanted with the CHARITE (TM) prosthesis. Of these 107, 100 were followed for a minimum of 10 years (range 10-13.4 years). A total of 147 prostheses were implanted with 54 one-level and 45 two-level procedures and I three-level procedure. The prostheses were placed through a standard anterior retroperitoneal approach. Clinically, 62% had an excellent outcome, 28% had a good outcome, and 10% had a poor outcome. Of the 95 eligible to return to work, 88 (91.5%) either returned to the same job as prior to surgery or a different job. These included 63.2% (12) of those working in heavy labor employment returning to the same job. Mean flexion/extension motion was 10.3 degrees for all levels (12.0 degrees at L3-L4, 9.6 degrees at L4-L5, 9.2 degrees at L5-S1). Mean lateral motion was 5.4 degrees. In the sagittal plane, 9 (6.1%) were anterior of geometric center, 50 (34.0%) were centered, and 88 (59.9%) were posterior of center. In the frontal plane, 110 (75%) were centered, and 37 (25%) were noted to be lateral to center. Slight subsidence was observed in two patients, but they did not require further Surgery. No subluxation of the prostheses and no cases of spontaneous arthrodesis were identified. There was one case of disc height loss of 1 mm. Five patients required a secondary posterior arthrodesis. A good or excellent clinical outcome rate of 90% and a return to work rate of 91.5% compare favorably with results described in the literature for fusion for the treatment of lumbar degenerative disc disease. With a minimum follow-up of 10 years, the CHARITE (TM) artificial disc demonstrated excellent flexion/extension and lateral range of motion with no significant complications.
