No difference seen in time to union with dynamic vs static screw configurations

Patients who had tibial fractures treated with exchange nailing using either a dynamic screw configuration or a static screw configuration had no significant difference in time to union, according to results.
Researchers compared time to healing of tibial nonunions among 52 patients treated with exchange nailing using screws in either a dynamically or statically locked configuration, with or without fibular osteotomy.
Although results showed patients proceeded to union 7.9 months and 7.3 months after revision surgery with dynamically locked nails and statically locked nails, respectively, this result was not statistically significant. Researchers noted a progression to union 2.9 months faster in patients with fibular osteotomy vs. patients without fibular osteotomy, which trended toward significance. Patients who were not obese experienced a faster healing rate compared with patients who were obese (6.8 months vs. 8.8 months), as did patients with closed fractures compared to patients with open fractures (6.4 months vs. 7.7 months). – by Casey Tingle
