Background: Several surgical techniques have been developed to reduce the nonunion rate and improve functional outcomes after displaced distal clavicle fractures, including the use of a tension band, the modified Weaver-Dunn procedure, coracoclavicular screw fixation, or locking plates. None of these techniques have been universally accepted, and each one has its own complications. To our knowledge, there are no previous publications describing osteolysis of the coracoid process caused by the tip of a cortical screw of a distal LCP plate. Case summary: We present the case of a 29-year-old male patient who had been treated with an anatomic pre-contoured plate for a distal clavicle fracture. Six months later he presented to our institution with limiting shoulder pain and tenderness upon the right coracoid process. Standard radiographs of the shoulder showed that the tip of a cortical screw was eroding the coracoid process. A surgery with hardware removal was then performed. One month after the surgery the patient was painless and with a full active shoulder ROM. Conclusion: Erosion of the coracoid process with plate screw fixation has never been described before. We suggest that extreme precaution should be taken in drilling and measuring the length of screws to avoid potential complications.
