Clinical Analysis Of MIPPO Technology And Intramedullary Nail Technology In The Treatment Of Tibial Shaft Fracture

Objective: The paper focuses on exploring the differences and the effects of treatment of tibial shaft fractures when MIPPO(Minnimally Invasive Percutaneous Plate Osteosynthesis)and intramedullary nail fixation are used.Methods: Retrospective analysis of clinical data of 45 patients with tibial shaft fractures who hospitalized in Department of Orthopedic in Shandong Provincial Traditional Chinese Medical Hospital from March 2013 to December 2014 was done. Sample data of 28 patients were randomly sent to the treatment group of MIPPO, and sample data of other 17 patients were sent to the treatment group of interlocking intramedullary nail. With corresponding internal fixation, surgery were undertaken in two groups respectively. Indicators were observed include peri-operative bleeding, operative time, postoperative fracture healing and curative effect,etc. The data obtained were analyzed using statistical software SPSS17.0.Results: Forty-five cases of patients were studied there. Operative time spent in the MIPPO technology group was significantly less than that in group of intramedullary nail technology. And there was no significant difference in peri-operative bleeding between the two groups. All patients underwent postoperative follow-up of from 5 to 16 months. It was found that the average healing time of 28 fracture patients was 4.3 ± 2 months after receiving treatment of MIPPO technology in the follow-up. One patient was found occurrence of postoperative incision infection.Another one patient was found appearance of delayed fracture healing. Another one patient was found occurrence of postoperative knee disorders. Two patients’ ankle plantar flexion were found limited after surgery.There was no patient found with obvious limb shortening.Therapeutic evaluation results of JOHNER-WRUHS was shown in the following: 17 excellent operative results were got and 9 good operative results were got.The excellent rate was 92.9%. The average healing time of 17 patients received the treatment of intramedullary nailing technology was 4.41 ± 2.29 months.One patient was found with limb shortening of about 5mm.Two patients were found with postoperative anterior knee pain.One patient had ankle movement disorder. But there was no postoperative infection, nonunion of fracture or other cases.Therapeutic evaluation results of JOHNER-WRUHS was shown in the following: 10 excellent operative results were got and 3 good operative results were got.The excellent rate was 82.4%.Conclusion:Both MIPPO technology and interlocking intramedullary nail technology follow the minimally invasive principle when used on the treatment of tibia shaft fractures.There are many advantages,such as smaller surgical wound, less peri-operative bleeding, lower rate of postoperative infection and quicker healing of postoperative fracture. Compared to the group of intramedullary nail technology, the group of MIPPO technology has some certain advantages in operative time and postoperative therapeutic evaluation over it.
