To assess the effect of flexor tenotomy in patients with diabetes on barefoot plantar pressure, toe joint angles and ulcer recurrence during patient follow-up.
Patients with a history of ulceration on the toe apex were included. They underwent minimally invasive needle flexor tenotomy by an experienced musculoskeletal surgeon. Dynamic barefoot plantar pressure measurements and static weight-bearing radiographs were taken before and 2-4 weeks after the procedure.
A total of 14 patients underwent flexor tenotomy on 50 toes in 19 feet. There was a mean follow-up time of 11.4 months. No ulcer recurrence occurred during follow-up. Mean barefoot plantar pressure was assessed on 34 toes and decreased significantly after the procedure by a mean 279 kPa (95% CI: 204-353; p < 0.001). Metatarsophalangeal, proximal interphalangeal and distal interphalangeal joint angles were assessed on nine toes and all decreased significantly (by 7° [95% CI: 4-9; p < 0.001], 19° [95% CI: 11-26; p < 0.001] and 28° [95% CI: 13-44; p = 0.003], respectively).
These observations show a beneficial effect of flexor tenotomy on biomechanical and musculoskeletal outcomes in the toes, without ulcer recurrence.
评估糖尿病患者屈肌腱切断术对足底压力、趾关节角度和溃疡复发的影响。
纳入有趾尖溃疡史的患者。由经验丰富的运动医学外科医生进行微创针式屈肌腱切断术。在手术前和术后 2-4 周，进行动态足底压力测量和静态负重 X 线检查。
共有 14 名患者的 50 个脚趾接受了屈肌腱切断术，涉及 19 只脚。平均随访时间为 11.4 个月。随访期间无溃疡复发。在 34 个脚趾上评估了平均足底压力，术后平均降低了 279kPa（95%CI：204-353；p<0.001）。在 9 个脚趾上评估了跖趾、近节和远节趾间关节角度，所有角度均显著降低（分别为 7°[95%CI：4-9；p<0.001]、19°[95%CI：11-26；p<0.001]和 28°[95%CI：13-44；p=0.003]）。
这些观察结果表明，屈肌腱切断术对趾部生物力学和肌肉骨骼结果有有益影响，且无溃疡复发。
