[Clinical effect of titanium cable assisted fixation combined with lengthened Gamma nail in the treatment of subtrochanteric fracture of femur].

OBJECTIVE

To investigate the clinical effect of titanium cable assisted fixation combined with lengthened Gamma nail in the treatment of subtrochanteric fracture of femur.

METHODS

From January 2010 to January 2018, 45 patients with long subtrochanteric fractures were retrospectively analyzed, and they were divided into two groups according to the operation plan. There were 24 cases of titanium cable assisted fixation combined with lengthened Gamma nail (observation group), including 14 males and 10 females, with an age of (54.2±12.8) years; 21 patients (control group) were treated with simple lengthened Gamma nail (control group), including 12 males and 9 females, with an age of (51.4±15.9) years. The operation time, intraoperative blood loss, hospital stay, hemoglobin decrease and fracture healing time were observed and recorded in the two groups. Harris hip function score was used to evaluate the postoperative curative effect, and the occurrence of complications was observed.

RESULTS

All patients were followed up for 14 to 36 months. There was significant difference in operation time, intraoperative blood loss, hospital stay between two groups(P<0.05). Three months after operation, the fracture healing rate of the observation group was 79.1%(19 / 24), which was higher than that of the control group 52.4%(11 / 21)(P<0.05). There was no significant difference in Harris hip function score 1 year after operation and fracture healing rate at 6 and 12 months after operation between the two groups (P>0.05). There were no complications such as deep infection, fracture of internal fixation and deep vein thrombosis of lower limbs in the two groups, and delayed healing occurred in 1 case in the control group.

CONCLUSION

Lengthened Gamma nail fixation is reliable in the treatment of subtrochanteric fracture. Limited incision titanium cable assisted fixation can improve the reduction rate and fixation strength of long segment fracture, which is conducive to early functional exercise.
