The purpose of this study is to evaluate the outcome of treatment for patients with Type IIIb open tibial fractures.

This study targeted 35 adult patients for whom follow-up was possible over one year after undergoing surgical treatment. There were 29 males and six females with an average age of 45 years.

Fracture location was proximal in 10 cases, midshaft in 13 cases, and the distal part of the tibia in 12 cases. An average of 10 days was observed for definitive fixation with soft tissue coverage of the injury. The mean time to radiographic union was 27 weeks. Sixteen cases (45.7%) of complications were observed. Three cases of superficial infection, two cases of deep infection, four cases of partial flap necrosis, three cases of mal-alignment, three cases of joint stiffness, and one case of hardware breakage were observed. The mean lower extremity functional scale score was 68.5 and the factors influencing the clinical results were severity of open wound (p=0.000) and occurrence of complications (p=0.000) according to results of multiple regression analysis.

In treatment of Type IIIb open tibial fractures, good clinical results can be expected provided that complications are prevented through proper reduction, firm fixation, early soft tissue reconstruction, and early rehabilitation.
