Comparing the standard tibial intramedullary nail with a micromotion tibial nail for unstable tibial fractures.

Prospective, Randomized-control Trial Comparing Standard Intramedullary Tibial Fixation With Micromotion Tibial Intramedullary Fixation

Not applicable Interventional University of Chicago · NCT06976801

This trial will test whether a micromotion tibial nail helps adults with unstable tibial fractures heal faster and have fewer complications than a standard tibial nail.

What this trial studies

Adults with unstable tibial shaft fractures will receive either a micromotion-design intramedullary nail or a standard intramedullary tibial nail and be followed after surgery. The study will collect radiographic union data, complication rates, and functional outcome measures through scheduled clinic visits and post-discharge contact. Perioperative details, infections, nonunion, and return-to-function metrics will be recorded and compared between the two groups. The trial is conducted at the University of Chicago using the institution's resources to maintain follow-up and perform a robust analysis.

Who should consider this trial

Good fit: Adults (age ≥18) with unstable tibial shaft fractures recommended for surgical intramedullary fixation who are ambulatory, present within four weeks of injury, have no active infection and no major immune or rheumatic disease, and can attend follow-up visits.

Not a fit: Patients with stable fracture patterns, delayed presentation (>4 weeks), non-ambulatory status, active infection, need for additional fixation strategies, significant immune or rheumatic disease, or inability to follow study procedures (including non-English speakers or those on workers' compensation) are unlikely to benefit.

Why it matters

Potential benefit: If successful, the micromotion nail could increase bone healing rates and reduce complications, improving recovery and function for patients with unstable tibial fractures.

How similar studies have performed: Intramedullary nailing is a well-established effective treatment for tibial fractures, but no randomized trials have directly compared micromotion-design nails to standard nails, so this head-to-head comparison is relatively untested.
