The treatment of infected nonunion of the tibia following intramedullary nailing by the Ilizarov method

The purpose of this study was to demonstrate the effectiveness of the Ilizarov method and circular external fixator in order to eradicate the infection and restore bone union, limb anatomy and functionality in cases with infected nonunion of the tibia following intramedullary nailing.During 7 years nine patients suffering from infected nonunion of the tibia after intramedullary nailing were treated in our department. The series comprised seven men and two women with an average age of 39.7 years (range 21-75 years). The patients had previously undergone an average of 4.8 operations (range 3-6 operations). Active purulent bone infection occurred in all nine patients. Bone defect was present in all patients with a mean size of 5 cm (range 2-12 cm). In three cases with bone defect less than 2 cm, monofocal compression osteosynthesis technique was used. In the rest cases where bone defect exceeded 2 cm, bifocal consecutive distraction-compression osteosynthesis technique was applied. Three patients required a local gastrocnemius flap. The mean follow-up period was 26.6 months (range 13-42 months). Results were evaluated using Paley's functional and radiological scoring system.Bone union was achieved in all nine patients without recurrence of infection during the follow-up period. Bone results were graded as excellent in five cases and good in the rest four cases. Functional results were graded as excellent in three cases, good in four and fare in two cases. Mean external fixation time was 187.4 days (range 89-412 days) and mean lengthening index was 32 days/cm (range 27-39 days/cm). Complications observed included eight grade II pin tract infections, axial deformity at the lengthening site in two cases and at the nonunion site in another two cases. Ankle joint stiffness was detected in five cases.The Ilizarov method may be an effective method in infected nonunions of the tibia following intramedullary nailing.

Persistent nonunion after grafted fibular fracture in congenital pseudarthrosis of the tibia. A case salvaged by repeated reconstructions

This is the case report of a boy with congenital pseudarthrosis of the tibia which was treated with free vascularized fibular transfer and had a difficulty with repeated reconstructions for the grafted fibula. It is important for orthopedic surgeons including the authors not to give up or shy away from the challenging treatment for such a cumbersome nonunion after fracture of free vascularized fibular graft for CPT.     

Radiographic union score for tibia fractures predicts success with operative treatment of tibial nonunion

BackgroundThe purpose of this study is to evaluate the ability of preoperative and postoperative radiographic union scores for tibia fractures (RUST) to predict treatment success of tibia fracture nonunion.Materials and methodsPatients presenting for operative treatment of tibia fracture nonunion were enrolled in a prospective data registry. Enrolled patients were followed at regular intervals for 12 months. Preoperative and 12 week postoperative radiographs were reviewed and scored using the RUST criteria. Postoperative time to union was determined by clinical and radiographic measures. Multivariate regressions were conducted to predict time to union using preoperative and postoperative RUST while controlling for treatment method. Receiver operating characteristic (ROC) curve was conducted to determine the accuracy of preoperative RUST in predicting failure of treatment.ResultsSixty-eight patients with aseptic tibia fracture nonunion treated operatively were identified. Sixty-one patients achieved union. Mean preoperative RUST was 7.5 (SD 1.4). Mean postoperative RUST was 9.2 (SD 1.4). Multivariate linear regressions demonstrated that preoperative (p = 0.043) and postoperative (p = 0.007) RUST are significant predictors of time to union after tibia fracture nonunion surgery. ROC curve demonstrated preoperative RUST below 7 was a good predictor of developing persistent tibia fracture nonunion (AUC = 0.83, Sensitivity = 1.000, Specificity = 0.745).ConclusionsRUST preoperatively and postoperatively predicts outcome after nonunion surgery. RUST can be used as part of the complete clinical picture to shape patient expectations and guide treatment.
