Abstract
Purpose
The purpose of this study was to determine whether anterior plating is better tolerated than superior plating for midshaft clavicle fractures.
Methods
This was a prospective non-randomized observational cohort study following operative vs. non-operative management of clavicle fractures from 2003 to 2018 at 7 level 1 academic trauma centers in the USA. The subset of patients treated with plate and screws is the basis for this comparative study. Adults aged 18–85 with closed clavicle fractures displaced over 100% or shortened by more than 1.5 cm were eligible for enrollment. Patients were followed for 2 years following enrollment. Allowable fixation methods at the discretion of the surgeon consisted of anterior–inferior or superior plating. A total of 412 patients were enrolled. Of these, 192 patients received either superior or anterior plating for a displaced clavicle fracture with complete documented prospective research forms capturing type of plating technique. The primary outcome measure was hardware removal (HWR). Secondary outcomes were Disability of the Arm Shoulder and Hand (DASH) score and Visual Analog Pain (VAP) score, and satisfaction score (1 = high satisfaction; 5 = low satisfaction).
Results
There was no difference in HWR rates (7.1% superior 9/127; 6.2% anterior 4/65, p = 0.81), VAP score (mean 1.5 SD 1.0 superior; mean 1.7 SD 0.6 anterior, p = 0.21), DASH score (mean 7.5 SD 12.4 superior; mean 5.2 SD 15.2 anterior; p = 0.18) or satisfaction score (mean 1.6 SD 1.0 superior; mean 1.7 SD 0.60 anterior, p = 0.18).
Conclusion
There is no difference in HWR rates or functional outcomes when using a superior vs. anterior plating technique.
