Intramedullary Nail Versus Plate Fixation Re-Evaluation Study in Proximal Tibial Fractures: A Multicenter Randomized Trial Comparing IM Nails and Plate Fixation (IMPRESS)

Location:

Rochester, Minn.

Trial status:

Open for Enrollment

Why is this study being done?

The study is a multicenter randomized controlled trial in which individuals sustaining a fracture of the proximal metaphysis of the tibia will be operatively managed by one of two strategies. The first strategy involves fixation of the fracture with a reamed, interlocking intramedullary nail (Nail Group). The second treatment strategy involves open reduction and internal fixation of the fracture with a locking periarticular plate (Plate Group). The null hypothesis of the study is that there will be no difference in the two groups with respect to the primary and secondary outcome measures. To the degree possible, patients in the two groups will receive post-operative care according to the same standards and protocols.

Who is eligible to participate?

Inclusion Criteria: - Skeletally mature, - Extra-articular fracture of the proximal tibia extending into the metaphyseal with or without intra-articular extension not requiring open reduction with complete AP and lateral radiographs, - Major fracture line not closer than 4cm from the proximal tibial articular surface - Fracture requiring operative treatment amenable to either IM nail or plate - Surgeon agreed to randomize patient - Informed consent obtained - Patient is English speaking Exclusion Criteria: - Tibial shaft fractures not amenable to intramedullary nailing (i.e.fracture is less than 4 cm from joint surface), - Fracture of the proximal tibia with intraarticular extension requiring open reduction, - Known metabolic bone disease - Separate displaced tibial tubercle fragment, - Soft tissue injuries compromising treatment method with nail,plate or both. - Fractures with vascular injury (Gustillo Type IIIC injury) requiring repair, - Compartment syndrome of the leg diagnosed preoperatively, - Pathological fractures, - Retained hardware or existing deformity in the affected limb that would complicate IM nailing,plating or both, - Symptomatic knee arthritis. - Surgical delay greater than 3 weeks for closed fractures or 24 hours for open fractures, - Immunocompromised, - Unable to comply with postoperative rehabilitation protocols or instructions (i.e. head injured or mentally impaired), - Current or impending incarceration, - Unlikely to follow-up in surgeon's estimation.
