Clinical Efficacy Observation of Minimally Invasive Percutaneous Steel Plate Internal Fixation(MIPPO)with Dual Plate Technique in the Treatment of Tibial Plateau Fractures
Objective:To observe the clinical efficacy of minimally invasive percutaneous plate internal fixation(MIPPO)dual plate technique in the treatment of Schatzker Ⅴ and Ⅵ type tibial plateau fractures,in order to evaluate its value.Methods:60 patients with Schatzker type V and Ⅵ tibial plateau fractures diagnosed in Zhijin County People's Hospital,Guizhou Province from February 2020 to May 2023 were enrolled.Among them,28 patients were treated with locking plates and assigned to the control group.Among them,32 patients were treated with MIPPO double plate technique and assigned to the observation group.Both groups of patients completed postoperative follow-up for more than 6 months,with four observation indicators set:comparison of surgical conditions,fracture healing,knee joint range of motion,and incidence of postoperative complications.Results:There was no significant difference in surgical time of(88.52±8.37)minutes and intraoperative blood loss of(282.53±51.28)mL between the observation group and the control group at(90.15±9.62)minutes and(279.85±49.85)mL,with no statistical significance(P>0.05).The observation group had a shorter callus formation time of(6.55±0.71)weeks and a fracture healing time of(11.46±0.25)weeks compared to the control group,with a callus formation time of(7.87±0.98)weeks and a fracture healing time of(13.42±0.37)weeks.The differences were statistically significant(P<0.05).The observation group had better knee joint extension(6.32°±0.41°)and knee joint flexion(93.25°±14.62°)than the control group in knee joint extension(8.61°±0.63°)and knee joint flexion(80.13°±10.15°),with statistical significance(P<0.05).There was no significant difference between the observation group and the control group in terms of weight-bearing time of(7.23±0.45)weeks and complete weight-bearing time of(13.89±1.22)weeks,with no statistical significance(P>0.05).The incidence of complications in the observation group was 9.37%(3/32)lower than that in the control group,which was32.14%(9/28),and the difference was statistically significant(P<0.05).Conclusion:For Schatzker Ⅴ and Ⅵ type tibial plateau fractures,MIPPO dual plate technology has a significant effect in treating tibial plateau fractures.This therapy can not only accelerate fracture healing,improve knee joint function,but also significantly reduce the incidence of complications.
