Abstract

Purpose

Chipping and lengthening over nailing (CLON) technique was developed to treat femoral shaft nonunion with shortening more than 10 mm. The purpose of the current retrospective case series was to clarify the effectiveness of the CLON technique on the femoral shaft nonunion following intramedullary nailing.

Methods

Clinical and radiological outcomes in the patients receiving operative treatment for femoral shaft nonunion between August 2012 and December 2016 were retrospectively reviewed using the Refractory Fracture Data Registry at the authors’ institution. The CLON technique was indicated for patients with the femoral shaft nonunion with shortening more than 10 mm.

Results

Five patients with median follow-up of 32 months (range, 14 to 50 months) were included in this study. All patients achieved bone union at the median of 8 months after the CLON technique. The median limb length discrepancy was 2.0 mm at the most recent follow-up.

Conclusions

The present study demonstrated that the CLON technique for femoral shaft nonunion may be the first choice as operative treatment for femoral shaft nonunion with shortening more than 10 mm.
