AO classification of distal femur fractures (illustration)

Background: The choice of distal femur locking plate in distal femur fractures has been a topic of debate. This study was performed to evaluate theresults of distal femur locking plate in distal femur fractures. Material and Methods: A prospective randomized study of 30 patients with distalfemur fracture was conducted at Department of Orthopaedics, Maharishi Markandeshwar Institute of Medical Sciences and Research, Mullana(Ambala), Haryana from January 2020 to July 2021 and followed up from 6months to 18 months for a minimum of 6 months duration. Implants used: The distal femur locking compression plate. Classification system: AO Classification. Results & Observations: Clinical and functional outcomes were assessed using Rasmussens functional knee score.Complications of fractures and operative treatment were assessed. The results of entire study group showed 18 excellent, 10 good, 1 fair and 1 poor. Conclusion: We observed and recommend that the distal femur LCP is an optimal tool of good fixation for fractures of distal femur.

Background: Distal femur fractures are common and need to be treated operatively and for optimal functional outcome. Multiple implants are available for fixation e.g. angled blade plate, dynamic condylar screw, buttress plate, antegrade nailing, retrograde nailing, locking distal femoral plates, external fixator etc. We have designed this study to analyse clinico-radiological outcome and competency of locked plating for all varieties of distal femur fractures.Methods: We conducted a prospective interventional study on 79 consecutive patients with fractures of distal femur operated with locking distal femur plate from January 2015 to February 2018. Patients were regularly followed up with x-rays and clinical examination. At the end of clinicoradiological union, patients were evaluated with Neer’s score.Results: Total 79 distal femur fractures were studied based on inclusion and exclusion criteria. There were 63 (79.75%) males and 16 (20.25%) females. As per AO classification fracture of type A were 39 (49.36%), type B were 10 (12.65%) and type C were 30 (37.97%). Average time period from injury to surgery was 8.2 days. In our study, the average period of clinicoradiological union was 16 weeks. 62 (78.48%) patients had excellent to satisfactory outcome, 13 (16.45%) patients had unsatisfactory and 4 (5.06%) patients had poor outcome.Conclusions: Distal femur fractures are common, complex injuries and different implant option are available for fixation. All types of distal femur fractures can be fixed using distal femur locking compression plate. If fixed following basic principles of fracture fixation good results can be obtained.
