A Multicenter Randomized Trial Comparing IM Nails and Plate Fixation in Distal Femur Fractures

Not Applicable
Completed
Conditions
Femoral Fractures
Interventions
Device: reamed, interlocking intramedullary nail
Device: locking periarticular plate
Registration Number
NCT00429663
Lead Sponsor
Boston Medical Center
Brief Summary

This study looks at two (2) types of surgical treatments and hopes to answer the question, "which is the best way to surgically treat a distal femur fracture?" Both procedures being studied are standard of care (used routinely) and use FDA approved devices. All medical and surgical treatment will be the same for participants as non-participants.

Detailed Description

The study is a randomized controlled multicenter trial in which individuals sustaining a fracture of the supracondylar (metaphyseal) region of the distal femur 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.

Primary Outcome Measures
NameTimeMethod
Short Musculoskeletal Functional Assessment (SMFA) Score3 months, 6 months, 12 months

The Short Musculoskeletal Functional Assessment (SMFA) score. The questionnaire consists of four categories: Daily Activities, Emotional Status, Arm and Hand Function, Mobility. All categories are scored together, totaling between 0-100. The lower the score, the better the subjects function.

EQ Index3 months, 6 months, 12 months

EQ Index is a visual analog scale that the subject uses to rank overall health and wellness on a scale of 0.00-1.00, 1.00 being best.

SMFA - Bother Index3 months, 6 months, 12 months

The Bother Index is part of the SMFA. This section focuses on how much the injury is bothering the subject in terms of daily activities and use of injured area. The index totals are between 0-100. The lower the score, the less bothered the subject is by their injury.

EQ-5D3 months, 6 months, 12 months

EQ-5D (EuroQol) Health Index taken at 3 months, 6 months, 12 months follow up. The EQ-5D measures the subjects health status in 5 categories (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and totals them into 1 score. Scoring ranges from 0-100, 100 being best.

Secondary Outcome Measures
NameTimeMethod
Valgus of Over 5 Degrees12 months

Valgus is a deformity involving oblique displacement of part of a limb away from the midline.
