High rates of arthrodesis nonunion have been described in the ankle, hindfoot and midfoot in patients with significant risk factors. The purpose of this study was to evaluate fusion rates, risk of reoperation, postoperative pain scores and patient satisfaction for a slot graft inlay arthrodesis technique used in a high-risk group of foot and ankle patients.
We retrospectively reviewed all ankle, hindfoot and midfoot arthrodeses by two foot and ankle surgeons in our institution between January 2000 and January 2009. Seventeen arthrodesis procedures in 16 patients using the slot graft technique were identified. Patient charts were reviewed for medical history, risk factors, previous surgery and postoperative complications. Time to union was evaluated on radiographs. Patients provided final followup by phone with an assessment of pain, overall satisfaction and use of orthotic or assistive devices.
Union occurred in 13 arthrodesis procedures (77%) with an average time to union of 5 months. Postoperative infection occurred in one patient. Additional surgery was performed in nine patients. At final followup patients reported low pain scores (3 of 10) and high satisfaction (8 of 10). Fourteen of 15 patients contacted indicated that they would choose to undergo the procedure again.
The slot graft arthrodesis technique provided satisfactory results in this small group of patients with a low complication rate. Patient satisfaction rates were high with low pain scores at an average of 62 months postoperatively.
在存在重大风险因素的患者中，踝关节、后足和中足融合术的非融合率较高。本研究的目的是评估 Slot 移植物镶嵌融合技术在高风险足踝患者中的融合率、再次手术风险、术后疼痛评分和患者满意度。
我们回顾了 2000 年 1 月至 2009 年 1 月期间，我院两位足踝外科医生进行的所有踝关节、后足和中足融合术。确定了 16 例患者的 17 例 Slot 移植物技术融合术。查阅患者病历，了解病史、风险因素、既往手术和术后并发症。通过 X 线评估愈合时间。患者通过电话提供最终随访，评估疼痛、总体满意度和使用矫形器或辅助设备的情况。
13 例融合术（77%）发生融合，平均愈合时间为 5 个月。1 例患者发生术后感染。9 例患者进行了额外手术。最终随访时，患者报告疼痛评分低（3/10），满意度高（8/10）。15 例中有 14 例患者表示愿意再次接受该手术。
在这组小患者中，Slot 移植物融合技术的并发症发生率较低，结果令人满意。患者满意度高，术后平均 62 个月时疼痛评分低。
