Superior clavicle plating using low-profile, precontoured locking plates has low complication and low hardware removal rate.

OBJECTIVE

The purpose of this study was to describe our experience using superiorly applied low-profile locking plates for the operative fixation of displaced midshaft clavicle fractures (MCFs).

STUDY

DESIGN

This was a retrospective analysis performed at an academic institution.

RESULTS

Eighty-three patients who presented with displaced, shortened MCFs were treated operatively by a single surgeon at our institution over a 10-year period. All patients received a precontoured low-profile locking plate applied in the superior position. A displaced midshaft clavicle fracture was fixed operatively using a precountered low-profile 2.7/3.5 mm locking plate applied in the superior position. Data were analyzed to evaluate time to union, final shoulder range of motion, incidence of hardware removal, and rate of postoperative complications. The cohort was 66.2% male with an average age at initial injury of 36.5 ± 14.1 years. At a mean of 3.6 ± 1.9 months, 99% of patients had united their fracture. At an average of 7.37-month follow-up, mean range of motion was 174° forward elevation, 173° abduction, 82° external rotation, and internal rotation to T7. Using the short musculoskeletal functional assessment (SMFA), the mean functional outcome index score was 4.12, bothersome index was 1.94, activity index was 1.55, emotion index was 2.51, arm and hand index was 1.14, mobility index was 0.68, and total index was 1.56. Ninety-two percent of patients had retained their hardware. There was 1 incidence of each of the following complications: infection, nonunion, hardware failure, and deep vein thrombosis.

CONCLUSION

Superior clavicle plating using precontoured low-profile locking plates is an acceptable treatment modality for displaced MCF. This method yields excellent results regarding time to union, shoulder range of motion, incidence of hardware removal, and the rate of postoperative complications. Patients considering operative fixation of displaced MCF should be counseled accordingly.
