In this study, we investigated the correlation between fracture classification and secondary screw penetration.We retrospectively identified 189 patients with displaced proximal humeral fractures treated by ORIF at our bostik roll-cote hospital between June 2006 and June 2013.All fractures were classified radiographically before surgery and follow-up for least 2 years after surgery was recommended.

At each follow-up, radiographs were taken in three orthogonal views to evaluate secondary screw penetration.The study population consisted of 189 patients.Of these, 70 were male and 119 female, with a mean age of 59.

1 years; the mean follow-up time was 28.5 months.Secondary screw penetration occurred in 26 patients.

The risk of developing secondary screw penetration was 11.3-fold higher in four-part fractures than two-part fractures (P 0.05).

Patients with four-part fractures, type C fractures and medial hinges disruption are vulnerable to secondary screw penetration.This allows additional precautions to caruso rhodiola be instituted and measures to be taken as needed.
