Background
Intramedullary clavicle fixation is a potential alternative to plate fixation. Previous studies documenting the complication rates of intramedullary clavicle fixation have demonstrated variable rates of soft tissue complications and fracture healing.
Questions/purposes
We asked the following questions: (1) Does use of the Rockwood Clavicle Pin (DePuy Orthopaedics Inc, Warsaw, IN) predispose patients to soft tissue complications requiring additional surgery or a high infection risk? (2) Does the Rockwood Clavicle Pin provide a truly minimally invasive insertion technique and reliable fracture fixation?
Patients and Methods
We retrospectively evaluated 18 patients (mean age, 31 years) who sustained a closed midshaft fracture of the clavicle treated with open intramedullary nailing with a Rockwood Clavicle Pin. We determined the incidence of complications and rate of fracture healing.
Results
Fourteen complications occurred in 10 patients. Five patients experienced a complication with fracture healing, including three nonunions. Nine patients experienced complications relating to soft tissue, including infection, skin necrosis, or posterior pain from pin prominence.
Conclusions
The Rockwood Clavicle Pin remains a historically relevant method of clavicle fixation. However, due to an unacceptably high rate of nonunion, repeat operation, and soft tissue complications, we do not recommend this device for treating middiaphyseal clavicle fractures.
Level of Evidence
