糖尿病患者扳机指的特点及治疗

目的 了解糖尿病人扳机指的发病特点，并对类固醇激素鞘内注射、手术这两种治疗方法的远期疗效予以评价。方法 对63例糖尿病人142个扳机指，并以63例非糖尿病人80个扳机指作为对照组进行回顾性研究。结果 对照组类固醇激素鞘内注射治愈率明显高于糖尿病组，有显著性差异；糖尿病组中非胰岛素依赖型糖尿病(NIDDM)患者局部注射及手术治愈率均高于胰岛素依赖型糖尿病(IDDM)患者，但无显著性差异；对照组手术治愈率高于糖尿病组，无显著性差异。糖尿病组多指受累发生率及弥漫型扳机指发生率均高于对照组，有显著性差异。结论 糖尿病人特别是IDDM病人扳机指比非糖尿病人扳机指治疗难度大，多指受累及需手术缓解症状的可能性大。

Characteristics and Treatment of trigger finger in diabetes

ve To study the features of tenosynovitis in diabetes and evaluate the long-term effect after steroid injections and surgery intervention in these patients. Methods 63 diabetic patients with 142 trigger digits [43 insulin-dependent diabetes mellitus (IDDM) and 20 non-insulin-dependent diabetes melli-tus (NIDDM) ] and 63 nondiabetic patients with 80 trigger digits as control group were analyzed retrospectively Results A higher recovery rate by steroid injection was achieved significantly in control group compared with the diabetic group (76.2% versus 50.7%), A higher successful surgery rate was ahcieved in control patients compared with the diabetic ones (94.7% versus 77%), but no significance. The IDDM patients exhibited a poorer successful rate than NIDDM patients by steroid injection (44.3% versus 69.4%) and surgery (76.3% versus 81.8%), but no significance. The incidence of multiple digit involvement and diffuse type were higher in IDDM patients (P < 0.01). Conclusions Diabetic patients, especially those with IDDM, are more likely to have multiple and diffuse trigger digits, which are intractable and more frequently require surgery intervention.
