Objective To explore the clinical effect of mini-incision approach reduction titanium cable combined with lengthened InterTAN intramedullary nail internal fixation in the treatment of Seinsheimer type V subtrochanteric fractures. Methods A retrospective analysis of 26 cases (27 hips) of patients with Seinsheimer type V subtrochanteric femoral fractures treated in our department from January 2017 to January 2020 in our department and using the mini-incision approach reduction titanium cable combined with lengthened InterTAN intramedullary nail internal fixation. Among them, there were 19 males and 7 females; the age was 39-76 years, with an average of 53.8 years old; the cause of injury: 15 cases of car accident injuries, 3 cases of falls, and 8 cases of fall injuries. Except for one case with bilateral injuries, the rest were unilateral injuries, with 10 hips on the right side and 17 hips on the left side. Fractures were classified as subtrochanteric Seinsheimer V type. The operation was pre-repositioned by traction bed, after maintenance, mini-incision approach and pre-cerclage reduction with titanium cable, and then internal fixation with lengthened InterTAN intramedullary nail. Hip joint score was used the Harris standard assesses hip joint function. Results All 26 patients in this group were followed up for 9 to 42 months, with an average of 17.2 months. At the last follow-up, the fractures were all healed, and the healing time was 12-25 weeks, with an average of 16.9 weeks. There were no complications such as vascular and nerve injury, wound infection, loosening and breaking of internal fixation, hip varus, and re-fracture. According to the patient's hip joint pain, function, range of motion and other conditions, the Harris hip scoring standard was used to evaluate the surgical effect: excellent in 18 hips, good in 7 hips, and fair in 2 hips, the excellent and good rate was 92.6%. Conclusion Mini-incision approach reduction of titanium cable combined with lengthened InterTAN intramedullary nail internal fixation for the treatment of Seinsheimer V-type femoral subtrochanteric fractures has the advantages of reliable fixation, fewer complications, and low failure rate. It is worthy of clinical application. |
