Abstract
Introduction: Distal femur fractures are commonly treated with retrograde intramedullary nails or lateral locked plates. Although enthusiasm is growing for dual-implant constructs, most fractures are still treated with a single implant, though it remains unclear whether one implant type offers superior outcomes. This study compared revision surgery rates as well as clinical and radiographic outcomes between matched cohorts of distal femur fractures treated with intramedullary nails or lateral plates.
Methods: This multicenter retrospective study included adult patients with OTA/AO 33A or 33C distal femur fractures treated with isolated retrograde intramedullary nails or lateral locked plates with a minimum 3-month follow-up at 10 level-1 trauma centers. Outcomes were compared between propensity-matched nail and plate groups including all-cause revision surgery, unplanned revision surgery to promote union, revision surgery for deep surgical site infection, and modified Radiological Union Scale for Tibia scores.
Results: A total of 245 fractures treated with intramedullary nails were propensity score-matched 1:1 to 245 fractures treated with a single locked lateral plate. At a mean follow-up of 16 months, no significant differences were found in all-cause revision surgery (24% vs. 19%, P = 0.2), revision surgery to promote union (8.2% vs. 10%, P = 0.5), revision surgery for infection (5.7% vs. 5.7%, P > 0.9), or modified Radiological Union Scale for Tibia scores at 3 months (9 vs. 9, P = 0.6). No notable differences were observed in radiographic postoperative reduction parameters, surgical duration, follow-up duration, or qualitative clinical outcomes between the nail and plate groups.
Conclusion: Distal femur fractures treated with retrograde intramedullary nails or lateral locked plates showed no notable differences in revision surgery rates, radiographic healing, or qualitative clinical outcomes. Surgeons should choose nails or plates based on experience, fracture type, and perceived ease of achieving a good reduction with the specific implant.
期刊介绍：
The Journal of the American Academy of Orthopaedic Surgeons was established in the fall of 1993 by the Academy in response to its membership’s demand for a clinical review journal. Two issues were published the first year, followed by six issues yearly from 1994 through 2004. In September 2005, JAAOS began publishing monthly issues.
Each issue includes richly illustrated peer-reviewed articles focused on clinical diagnosis and management. Special features in each issue provide commentary on developments in pharmacotherapeutics, materials and techniques, and computer applications.
