Intramedullary Fixation of Diaphyseal Clavicle Fractures Using the Rockwood Clavicle Pin: Review of 86 Cases

Abstract

AIM: This study reports the safety, efficacy and functional and patient centred outcomes of the largest published series of patients treated with the Rockwood clavicle pin (intramedullary device) to date. PATIENTS AND METHODS: A retrospective review of case notes, radiographs and follow-up by questionnaire was conducted. 86 patients were operated upon, 70 for acute fractures (group A) and 16 for non-union (group B). RESULTS: Rate of non-union was 2 (2.9%) in group A and 0 in group B. Mean Disability of the Arm, Shoulder and Hand (DASH) scores were 5.9 for group A and 8.7 for group B. Satisfaction was rated as good or excellent in 61 (96.8%) of responders and all patients would have the procedure again. Pin prominence was the predominant complication in both groups and all patients underwent a second procedure for metalwork removal. DISCUSSION: Rockwood clavicle pins are as effective as plates in achieving union and maintaining length, however the advantages of this less invasive technique should be weighed against the common complication of pin prominence and the inconvenience of removal of metalwork in all cases.
