Outcomes of young active patients with displaced clavicle fractures treated with Rockwood pin

Various fixation techniques have been described for midshaft clavicle fractures in the literature. We hypothesized that use of the Rockwood pin for fixation of displaced midshaft clavicle fractures would result in favorable outcomes in a young active cohort.

Patients aged 10-35 years who underwent Rockwood clavicle pin fixation at a single institution were identified. Preoperative and postoperative radiographs were reviewed and assessed for fracture characteristics, postoperative alignment, and radiographic union. Postoperative outcome scores were obtained.

A total of 39 patients (age 17.3 ± 3.9 years) with clavicle fracture treated with Rockwood pin were identified. Radiographic review demonstrated that 88% of fractures were 100%, or more, displaced, and surgery achieved near-anatomic reduction in 92% of cases. Average time to radiographic union was 2.3 ± 0.8 months, and average time to clinical union was 2.5 ± 0.3 months. One patient required revision for nonunion (3%). Complete outcome responses were obtained for 24 patients, with an average 40 ± 27.7 months of follow-up. Mean Total Clavicle Functional score was 2.75 ± 3.6 for minor patients. For adult patients, Nottingham Clavicle score was 90.7 ± 10.7, mean American Shoulder and Elbow Society score was 92.4 ± 11.2, and mean Single Assessment Numerical Evaluation score was 88.8 ± 21.5. 77% of adults reported no long-term functional limitation; 54% reported a bump at the prior fracture site, but 100% reported satisfaction with shoulder appearance.

In our cohort of young active patients, treatment with Rockwood pin allowed for anatomic reduction, healing with a low nonunion rate, and favorable patient reported outcomes.
