Abstract: Aim – To study callus occurring in diabetic foot and distributing them through Amit Jain’s extended ‘SCC’ classification. Methods & materials – A descriptive retrospective analysis was done at Amit Jain’s Institute of Diabetic Foot & Wound Care at Brindhavvan Areion Hospital, Bengaluru, India. The study period was from December 2018 to November 2019. SPSS 22 was used for statistical analysis. Results – 30 patients were studied. Most of them were males and most were between 61-70 years old. Right foot was affected in 46.7%. All the cases of calluses were in forefoot in this study. Metatarsophalangeal joint was the most commonly affected site (50%). 53.3% of the callus was less than 2 cm in size. Type 1 callus was most common callus affecting 53.3% followed by type 2 callus. Type 3 callus were significantly multiple in number compared to type 1 and 2 callus. Antibiotics was used only for type callus as they had underlying infection. Conclusion- Diabetic foot callus are common in clinical practice and they are common in older people. Type 1 callus are most commonly seen in this study. Amit Jain’s classification is a new simple, easy, practical classification for callus which can effectively categorize all the calluses into any of the 3 types and it guides in treatment.
