To retrospectively assess the clinical and functional outcomes of a group of patients receiving Charitè lumbar disc replacement and to compare those outcomes to the corresponding surgical technical accuracy.
A retrospective study of all patients treated over a 3-year period was undertaken. Objective pain scores were quantified from 1 to 10. Short Form 36-Health Survey (SF-36v2) scores were compared to Australian population norms. Surgical placements were radiographically classified. Heterotopic ossification, disc height restoration and angle-defined instability were assessed using established protocols.
Twenty-five patients were identified with three patients lost to follow-up. Average follow-up was 34 months. Ideal surgical placement was achieved in five (33%) single-level and three (37.5%) dual-level disc replacements. Sub-optimal surgical placement was seen in nine (60%) single-level and five (62.5%) dual-level disc replacements. Poor surgical placement was observed in a single-level disc replacement. All patients demonstrated a reduction in objective pain score (P < 0.05). SF-36v2 outcomes were superior in single-level compared to dual-level and ideal compared to sub-optimal replacements (P < 0.05).
The hypothesis that ideal surgical placements are associated with improved clinical and functional outcomes in total lumbar disc replacement was confirmed.
回顾性评估接受 Charitè 腰椎间盘置换术治疗的一组患者的临床和功能结果，并将这些结果与相应的手术技术准确性进行比较。
对 3 年内接受治疗的所有患者进行回顾性研究。客观疼痛评分从 1 到 10 进行量化。使用澳大利亚人群标准比较了短格式 36 健康调查（SF-36v2）评分。对手术位置进行了放射学分类。使用既定方案评估异位骨化、椎间盘高度恢复和角度定义的不稳定性。
确定了 25 名患者，其中 3 名患者失访。平均随访时间为 34 个月。在 5 例单节段（33%）和 3 例双节段（37.5%）椎间盘置换术中实现了理想的手术位置。在 9 例单节段（60%）和 5 例双节段（62.5%）椎间盘置换术中观察到次优的手术位置。在单个节段椎间盘置换术中观察到较差的手术位置。所有患者的客观疼痛评分均降低（P < 0.05）。单节段的 SF-36v2 结果优于双节段，理想的手术位置优于次优的手术位置（P < 0.05）。
理想的手术位置与全腰椎间盘置换术的临床和功能改善结果相关的假设得到了证实。
