Severe open fractures of the tibia (shin) bone are difficult to treat and are associated with high rates of infection and other complications. There is controversy regarding the best treatment, particularly in fractures with large wounds from trauma. The two current standard treatment options are to place an internal fixation device (a nail or plates with screws) or to use a device with pins that stick out of the skin and attach to rings outside the body (modern ring external fixator). It is unknown which of these standard of care treatment options will result in lower complication rates and better function of the leg.~Our goal is to perform a multi-center randomized controlled trial of the use of modern ring external fixation versus internal fixation for fracture stabilization of severe open tibia fractures. Patients who refuse randomization have the option of participating in a prospective observational study and the treatment is decided by the surgeon and patient.~Primary Aim: To compare the outcomes associated with modern ring external fixators versus standard internal fixation techniques in treating severe open tibia shaft or metaphyseal fractures with or without a bone defect of any size.~Primary Hypothesis: Among patients with open tibia shaft or metaphyseal fractures (with or without a bone defect of any size), the rate of re-hospitalization for major limb complications will be lower for patients treated with ring fixators than those treated with standard internal fixation.~Secondary Hypotheses: Among patients with open tibia shaft or metaphyseal fractures (with or without a bone defect of any size), the overall rate of infections will be lower for patients treated with ring fixators than those treated with standard internal fixation. Measures of fracture healing, limb function, and patient reported outcomes (including pain) will be as good or better among patients treated with ring fixators than those treated with standard internal fixation.~Secondary Aim #1: To determine the percentage of Gustilo IIIB open tibia shaft fractures that can be treated successfully (i.e. without amputation) without a soft tissue flap secondary to the use of ring external fixators.~Secondary Aim #2: To determine the two-year treatment costs associated with fixation of severe open tibia shaft or metaphyseal fractures (with or without a bone defect of any size) using modern ring external fixators versus standard internal fixation techniques.~Secondary Aim #3: To determine patient reported levels of satisfaction with the fixation method and overall treatment and to compare satisfaction between the two treatment groups.
The purpose of this study is to compare the use of modern ring external fixation versus internal fixation for fracture stabilization of severe open tibia fractures.
