Application of Percutaneous Clamp Reduction in 36 Cases of Distal Femoral Fracture
Objective:To investigate the safety and efficacy of percutaneous clamp reduction in the operation of distal femo-ral fracture.Methods:The data of 36 patients with distal femoral fracture treated by percutaneous clamp reduction combined with retrograde intramedullary nail from January 2019 to December 2022 were retrospectively analyzed.There were 20 males and 16 females.Age ranged from 25 to 88 years old,with an average age of 63.5 years old.There were 17 cases on the left side and 19 on the right side.According to AO/OTA classification,A2.1 type was 10 cases,A2.2 type 12 cases,A3.1 type 9 cases,C1.1 type 5 cases.The causes of injury were traffic injury in 6 cases,fall injury in 23 cases and drop injury in 7 cases.All patients with distal femoral fractures were treated with percutaneous clamp reduction,and then with closed reduction and retrograde intramedullary nail fixation after the reduction was satisfactory.The injury of blood vessels and nerves was observed during operation.The reduc-tion of fracture,healing time of fracture and postoperative complications were observed after operation.Schatzker-Lambert score of knee function was performed at fracture healing.Results:All 36 cases were followed up for 8 to 14 months,with a median of 12 months.There were no cases of vascular and nerve injury.No cases of infection;Postoperative radiographs showed good alignment of fracture end.All cases healed well,and no cases of non-union or delayed union occurred.The healing time of fractures was 12-24 weeks,with a median of 16 weeks.Schatzker-Lambert function score:excellent 25 cases,good 8 cases,medium 3 cases,excellent and good rate of 91.67％.Conclusion:The application of percutaneous clamp reduction in the operation of distal femoral fracture has the advantages of simple operation,minimally invasive,safe and efficient,shortening operation time,reducing intraoperative flu-oroscopy times and blood loss,contributing to the smooth development of subsequent operations,improving clinical efficacy,and worthy of clinical application.
