Plate fixation of midshaft clavicle fractures for delayed union and non-union is a cost-effective intervention but functional deficits persist at long-term follow-up.

Background:The primary aim of this study was to compare the long-term functional outcome of midshaft clavicle fracture fixation for delayed (≥3 month) and non-union (≥6 month) compared to a matched cohort of patients that achieved union with non-operative management. The secondary aim was to assess cost-effectiveness of fixation. Methods:A consecutive series of patients over 10-years were retrospectively reviewed using the QuickDASH, Oxford Shoulder Score and EuroQol five-dimension summary index (EQ-5D). These patients were compared to a matched cohort that achieved union after non-operative management using propensity score matching. Results:Sixty patients (follow-up 79%, nnppppConclusions:Clavicle fixation for delayed and non-union is a cost-effective intervention but outcomes are worse compared to patients that unite with non-operative management.
