Clinical Research of Interlocking Intramedullary Nail with Blocking Screws in the Treatment of Lower Extremity Long Bone Metaphyseal Fractures
Abstract： Objective:To investigate and assessment the clinical efficacy and notes in the treatment of interlocking intramedullary nail with the blocking screws fixation of lower extremity long bone metaphyseal fractures.Methods:From January 2008 to December 2009,26 cases of lower extremity long bone metaphyseal fractures were surgical treatment and used the interlocking intramedullary nail fixation combined with blocking screws,in them including 15 cases of distal tibial fractures,11 cases of distal femur;Closed fractures were 23 cases and open fractures were 3 cases.Postoperative follow-up assessment of quality of fracture reduction and healing.Results:38 blocking screws were used in 26 cases,26 cases were all followed up for 12-18 months,with an average of 15.2 months.All the fractures were bone union,the average healing time was 5.1 months.All fracture healing angle less than 5°,no fracture shift and ends instability phenomenon,not fond common soft tissue complications such as severe swelling,infection and other phenomena.The blocking screw and interlocking intramedullary nail fixation system were stable position,did not appear the complications such as internal fixation loosening,deformation,displacement and fracture.Conclusion:Blocking screw technology can effectively enhance the quality of fracture reduction in lower extremity long bone metaphyseal fractures treated with interlocking nails,and increase the stability of fracture fixation,thereby expanding the range applications of the intramedullary nail.
