Clinical efficacy of top rod support method combined with minimally invasive dual channel technology in the treatment of refractory intertrochanteric frac-tures of the femur with different clinical classifications
Objective To evaluate the clinical efficacy of top rod support method combined with minimally invasive dual channel technology in the treatment of different clinical classifica-tions of refractory intertrochanteric fractures of the femur.Methods One hundred and thirteen patients with intertrochanteric fractures of the femur who received treatment in the Affiliated Hospital of Xuzhou Medical University from January 2020 to August 2023 were collected.Based on the displacement of the proximal head and neck bone fragments of the fractures,patients with refractory intertrochanteric fractures were divided into 3 groups,including 49 cases of rota-tional type group,28 cases of twisted lock type group,and 36 cases of reverse rotor type group.All patients were treated with top rod support method combined with minimally invasive dual channel technology,and the surgical time,intraoperative blood loss,fracture reduction time,fracture healing time,fracture reduction status(neck shaft angle,lateral angle,lateral overlap rate of fracture end,anterior posterior overlap rate of fracture end),fracture reduction quality,Harris score of hip joint,postoperative complications and other indicators in each group of patients were compared and analyzed.Results In terms of surgical time,intraopera-tive blood loss,fracture reduction time,and fracture healing time,there were significant differ-ences among the three groups of patients(P＜0.05).The interlocking group showed the shor-test surgical time and the smallest blood loss,followed by the rotating group,while the reverse rotor group showed the longest performance;There were significant differences among the three groups in terms of neck shaft angle,lateral angle,lateral overlap rate of fracture end,and ante-rior posterior overlap rate of fracture end(P＜0.05);The rotary and twisted lock groups per-form relatively well on these indicators,while the reverse rotor group performs relatively poorly;The evaluation of the quality of fracture reduction showed no significant difference among the groups(P＞0.05),with grade Ⅰ being the main factor and grade Ⅳ being less common;The Harris score of the hip joint in all three groups at 3 months after surgery was significantly higher than before,and there were significant differences in pain,function,deformity,range of mo-tion,and total score among patients(P＜0.05);There was no significant difference among the three groups of patients in terms of non union of fractures,incision infection,fixation detach-ment,and overall outcome(P＞0.05).Conclusion The combination of top rod support re-duction and minimally invasive dual channel technology is an effective and safe method for the treatment of refractory intertrochanteric fractures of the femur,especially in reducing surgical time and intraoperative blood loss,showing good clinical advantages.
