ABSTRACT
Objective To compare the clinical results between minimally invasive percutaneous plate osteo-synthesis(MIPPO) and interlocking intramedullary nail(IIN) for treatment of tibia fracture. Methods 50 eases with tibia fracture were treated with MIPPO technique and 35 cases were treated with IIN. Five factors including surgery time ,intereperation bleeding,in hospital time, healing time and complications were studied statistically to analyze the two kinds of internal fracture fixations. All the patients were followed up for 12 ～ 30 months after operation( average 16months). Compare the condition of limb functional recover between the two kinds of internal fracture fixations accord-ing to Johner-Wruhs standard. Results The operating time [ ( 96.5±5. 0) min ], the bleeding [ ( 60.3±6.6 ) ml ] and the bone healing time [ ( 16.2±7.4) week ] in MIPPO group were significantly lower than in the IIN group ( allP <0.05). The operating time was( 170.6±6.2) ml,the bleeding was( 110.0±8.5)min and the bone healing time was (19.5±5.6)week in the IIN group. While there were no significant difference in hospital time,Johner-Wruhs system and the complications between IIN and MIPPO group( allP>0.05). Conclusion It has high cure rate and long-term curative effect that the two kinds of internal fracture fixations for treatment of tibia fracture. The.technique of MIPPO has the advantages of small trauma and quickly recovery characteristics. It was a ideal therapy in treatment of tibia fracture.
