Pin Tract Infection Following Correction of Charcot Foot With Static Circular Fixation

Background:The traditional nonsurgical accommodative treatment for diabetes-associated Charcot foot arthropathy has been unsuccessful in improving the quality of life in affected individuals. This has led to the growing interest in surgical correction of the acquired deformity with either “super construct” internal fixation implants or fine-wire static circular external fixation. The use of static circular external fixation without implants has been demonstrated to achieve high rates of deformity correction with low complication rates. The goal of this investigation was to assess the risk of pin site infection in this high-risk patient population.Methods:Over an 11-year period, 283 consecutive diabetic patients underwent single-stage correction of Charcot foot deformity with static fine-wire circular external fixation and no internal fixation devices. Pin care was minimal.Results:Fifty-nine (20.8%) patients developed clinical signs of pin tract infection in at least 1 pin site. Forty-nine occurred in pati...
