A Post-Market Clinical Evaluation of the Treatment of Tibia Fractures With the T2 Alpha Tibia Nailing System

Study Overview
=================
Brief Summary
-----------------
This investigation is a prospective, multi-center clinical investigation. It is anticipated that a total of 80 subjects will be enrolled. Neither subjects nor investigators are blinded to treatment and the clinical investigation includes a historical control which will be compared to the T2 Alpha Tibia Nailing System. Total duration of enrollment, 12 month follow-up and analysis is expected to take 31 months. The clinical investigation has been designed to follow the surgeon's standard of care for tibia fractured subjects, in addition to a 12 month follow-up visit. The primary endpoint of this clinical investigation is to confirm efficacy/performance at 12 months, as measured by the SF-36 Physical Component Summary (PCS). Confirmation of efficacy/performance at 12 months will be based on an equal or higher (non-inferior) SF-36 Physical Component Summary (PCS) result of the T2 Alpha Tibia Nailing System compared to the benchmark literature.

Detailed Description
-----------------
The objective of this clinical investigation is to demonstrate the safety and efficacy/performance of the T2 Alpha Tibia Nailing System. Efficacy/performance of the procedure will be measured by an equal or higher (non-inferior) SF-36 Physical Component Summary (PCS) score result of the T2 Alpha Tibia Nailing System compared to the T2 Tibia benchmark literature at 12 months. In addition, demonstration of bone consolidation in correct alignment will be measured by Investigator assessment by 12 months. Safety of the T2 Alpha Tibia Nailing System will be demonstrated through reporting of device related intra-operative and post-operative Adverse Events/incidents by 12 months.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| SF-36 PCS (36-Item Short Form Health Survey Physical Component Summary) | The primary endpoint of this clinical investigation is to confirm efficacy/performance at 12 months, as measured by the SF-36 PCS (36-Item Short Form Health Survey Physical Component Summary). The SF-36 PCS is a self-report measure of health status. SF-36 Physical Component Summary scores range from 0 to 100; higher SF-36 score results are linked to better subject results. Confirmation of efficacy/performance at 12 months will be based on an equal or higher (non-inferior) SF-36 Physical Component Summary (PCS) result of the T2 Alpha Tibia Nailing System compared to the T2 Tibia benchmark literature. | 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety will be measured by capturing the incidence rate of device-related adverse events | Incidence of device-related adverse events will be monitored by 12 months through data collection and analyses. | 12 months | 
| Efficacy/Performance will be measured by demonstration of bone consolidation | Bone consolidation will be assessed by 12 months as measured by Investigator assessment. | 12 months |
