Abstract

Objective To compare the clinical efficacy of minimally invasive tube channel technique and traditional open technique in the treatment of femoral shaft nonunion. Methods Between March 2016 and June 2018, a total of 29 patients with femoral shaft nonunion were included into this study. Thirteen of these patients underwent minimally invasive surgery via the tube channel (tube channel group), while another 16 patients received traditional open surgery (open group). The healing of femoral shaft nonunion was evaluated based on the Tohner-Wrnch criteria and the postoperative function was evaluated according to SF-36 scores. Results There was no significant difference in age, gender, bone nonunion types, duration of bone nonunion or length of follow-up between the two groups. The incisions in the tube channel group [(6.38±1.45) cm] were significantly smaller than those in the open group [(20.56±7.69) cm, P=0.003]. The duration of surgery [ (116.15±23.29)min vs. (250.75±53.82)min] and intra-operative blood loss [(105.00±15.00)ml vs. (565.63±239.94)ml ]were significantly shorter or less in the tube channel group (P＜0.05). The femoral shaft nonunion was healed and the excellent and good rate of clinical outcomes was 100% in both groups during the last follow-up. There was no significant difference in SF-36 physical function scores or bodily pain scores between the two groups. Conclusions The minimally invasive tube channel technique has the advantages of easy operation, shorter duration of surgery, decreased blood loss, and reduced iatrogenic damage, which is an ideal treatment.
