This retrospective study examined 132 adults with united middle-third clavicle fractures treated conservatively. The central question: does the degree of clavicular shortening after union predict clinical dissatisfaction? The study found gender-specific shortening thresholds beyond which poor outcomes become significantly more likely.
When counseling a patient with a displaced midshaft clavicle fracture about conservative management, shortening is the number to watch — and it varies by sex.
Shortening greater than 18 mm in a male or 14 mm in a female predicts a significantly higher rate of dissatisfaction. These thresholds emerge from the observation that normal clavicular length itself differs meaningfully between sexes (190 mm vs 140 mm), so the same absolute shortening carries different proportional consequences.
Nearly 26% of conservatively treated patients in this series were dissatisfied at 30 months. That figure is worth sharing with patients before treatment, and it frames why some surgeons favor operative fixation for significantly shortened or displaced fractures in active patients.
The study also highlights a methodologic point relevant to reading the literature: prior series that pooled males and females into one cohort produced shortening thresholds that don't apply cleanly to either group. When evaluating studies on midshaft clavicle outcomes, check whether sex was analyzed separately.
