Objective: Obesity is a risk factor for calcaneal spur (CS) formation. Diabetes mellitus may contribute to the risk of CS due to the decreased ability of tissue repair and peripheral neuropathy. Thus, we aimed to determine the frequency of CS in asymptomatic obese subjects with and without type 2 diabetes mellitus (T2DM). Also, we tried to find the related factors of CS in patients with T2DM. Material and Methods: Ninety-three obese patients with type-2 diabetes mellitus (T2DM) and 42 obese control subjects without glucose metabolism disturbances were enrolled in the study. A questionnaire was made about the duration of T2DM, age, and occupations of the participants. Physical, laboratory, and x-ray examinations of all cases were made. SPSS 15.0 was used for statistical analyses. Results: Patients with T2DM and control groups were similar in mean age and body mass index (BMI) (p=0.196, p=0.073, respectively). The existence of CS in the T2 diabetic group was significantly higher than in the control group (p=0.023). T2 diabetic patients with CS had significantly higher neuropathy existence, mean age, and BMI than T2 diabetic patients without CS (p=0.001, p=0.016, p=0.043, respectively). There was a positive correlation between the existence of CS and peripheral neuropathy and age (p=0.025, p=0.001, respectively).
Conclusion:Increased ratio of CS in obese T2 diabetic patients may be important because of the relation between CS existence and complications of diabetes mellitus. Clinicians should pay more attention to increased frequency of CS in patients with T2DM, to avoid diabetic foot complications and other malformations.
