BACKGROUND: The successful treatment of @entity3202 tibia non-unions and tibia non-unions with large bone defects or @entity281 is a major challenge in orthopedic and @entity130 surgery. This article evaluates the use of the 'diamond concept' using a one-step or two-step procedure according to 'Masquelet technique' in the treatment of @entity3202 tibia non-unions. METHODS: Between February 2010 and March 2014, 102 @entity1 with @entity3202 were treated according to the 'diamond concept' in our center. Ninety-nine were available for follow-up. Forty-nine received a one-step treatment (Group 1, G1) and 50 @entity1 received a two-step treatment according to the 'Masquelet technique' (Group 2, G2). Clinical and radiological parameters were measured preoperatively as well as 4, 6, and 12 weeks and 6 and 12 months postoperatively. In order to evaluate the subjective health of @entity1 , we used the SF-12 questionnaire. Data analysis was performed one year after treatment. RESULTS: The rate of consolidation in G1 was 84% and 80% in G2. The time to heal in G2 was 8.6    2.9 months, which is significantly longer than in G1 being 6.9    3.1 months. In comparison @entity1 in G1/G2 had an average of 3.2/6.7 previous major surgeries. In G1, 4 of 8 @entity1 who did not heal successfully showed positive intraoperative cultures. In G2, 26 @entity1 (52%) initially presented with positive cultures. The results of the SF-12 questionnaire improved in both groups during the postoperative follow-up, but showed no significant differences between groups. In 29 @entity1 a @entity801 -coated nail was used for reosteosynthesis. These @entity1 showed by trend a lower rate of complications at a higher rate of consolidation. CONCLUSIONS: Our study showed that the 'diamond concept' is a suitable method for safely and effectively treating non-unions with large defects or @entity281 . The use of an antibiotic-coated nail provides a therapeutic benefit. For large bone defects of infected non-unions the two-step procedure after Masquelet is an efficient way to eradicate the @entity281 and treat the @entity79 successfully.
