Abstract：
Hallux ulcers are known for their recurrence and associated risk for future amputations. Traditional nonsurgical external offloading methods have poor compliance rates, and the data is sparse on surgical offloading of hallux ulcers. We performed this study to analyze the outcomes of Keller excision gap arthroplasty of the first metatarsophalangeal joint in patients with a neuropathic plantar hallux interphalangeal joint (IPJ) ulcer in patients with diabetes mellitus.
A retrospective study of 105 diabetic patients with a plantar hallux IPJ ulcer who underwent a Keller excision gap arthroplasty between December 2014 and June 2020 was done. A total of 122 great toes had been operated upon for hallux IPJ ulcers. We studied the long-term wound healing rates from patient records and then did a prospective survey of the postreview period.
All the hallux IPJ ulcers healed well in the immediate postoperative period. Six patients reported a recurrence of the ulcer at the original site during a mean follow-up period of 30 months. For these 6 patients, the mean time to recurrence of ulcer after operation was 2.5 years.
At an average of 30 months, we found the Keller gap arthroplasty for treatment of noninfected and nonischemic diabetic foot hallux IPJ ulcers was associated with an ulcer recurrence rate of 5%.
Level IV, cohort study.

摘要：
未经证实：Hallux溃疡因其复发和未来截肢的相关风险而闻名。传统的非手术外卸载方法的依从率差，手术卸载拇指溃疡的数据很少。我们进行这项研究是为了分析糖尿病患者的神经性足底趾指间关节（IPJ）溃疡患者的第一meta趾关节Keller切除间隙置换术的结果。
UNASSIGNED：对2014年12月至2020年6月期间接受Keller切除间隙关节成形术的105例患有足趾IPJ溃疡的糖尿病患者进行了回顾性研究。总共对122个大脚趾进行了手术治疗。我们从患者记录中研究了长期伤口愈合率，然后对后期进行了前瞻性调查。
UASSIGNED：所有的耻骨IPJ溃疡在术后即刻愈合良好。在30个月的平均随访期内，六名患者报告了原始部位的溃疡复发。对于这6名患者，术后溃疡复发的平均时间为2.5年。
未经评估：平均30个月，我们发现,Keller间隙关节置换术治疗非感染性和非缺血性糖尿病足-足IPJ溃疡的溃疡复发率为5%.
未经批准：四级，队列研究。
