Tibial shaft fractures treated with intramedullary nailing and reduction device assistance

This study aimed to assess the outcomes of a newly invented reduction device on assisting reduction of intramedullary nailing (IMN) in the treatment of tibial shaft fractures.

From January 2015 to December 2018, data of patients with tibial shaft fractures treated with IMN were reviewed. In total, 42 patients underwent treatment with the new reduction device (group A) and 56 underwent treatment using a traditional reduction technique (group B). Data related to the closed reduction rate, surgical time, blood loss, number of fluoroscopies, number of surgeons, and number of complications were also reviewed. Fracture healing was assessed using radiographs at each follow-up, and the functional outcome (AOFAS score) was evaluated at the final follow-up.

The two treatment groups were evenly matched with respect to age, sex, fracture grade, and time to surgery. The average surgical time, blood loss, number of fluoroscopies, and number of surgeons in group A were all lesser than those in group B (P < 0.05). The closed reduction rate in group A was higher than those in group B (P < 0.05). The fracture healing time, AOFAS score, and complication rate were not significantly different (P > 0.05) between the two groups.

The new reduction device could effectively achieve and maintain the reduction of tibia shaft fractures in a minimally invasive fashion.
