Calcaneal fractures in diabetic patients.
We would like to present 23 calcaneal fractures in 22 patients of whom 21 had type I diabetes mellitus. There appear to be three basic fracture types: (1) a superiorly displaced extra-articular avulsion fracture of the posterior calcaneus (or Iowa fracture), which occurred in 12 patients (five men, seven women); (2) a mid-calcaneal compression fracture in six patients (four men, two women), and (3) a cleavage or "wedge" type fracture in four patients extending from the calcaneal tubercle (one man, 3 women). All four of this last group of patients had a history of a chronic penetrating ulcer, and this is noteworthy since only one other patient out of the remaining 18 in groups 1 and 2 had a similar history. Most patients had decreased bone mineralization: 15 patients were on long-term, high-dose steroids, and 18 patients had either poor renal function or complete renal failure (11 of 12). Fourteen patients had received either renal or pancreas transplants. Eight patients were on restricted weight bearing prior to their fractures. We believe that diabetic patients are more prone to calcaneal fractures than the general population, and early diagnosis is imperative, followed by early treatment to prevent significant bony deformity.
