Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
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.
