Comparison of outcome of lambda plate versus double plate fixation in AO Type C fractures of distal humerus in adults.

Objective: To compare the outcome of lambda plate versus double plate fixation in AO Type C fractures of the distal humerus in adults regarding bone union, range of motion and MEP score. Study Design: Randomized Clinical Trial. Setting: Sheikh Zayed Hospital, Lahore. Period: 1-01-2020 to 31-12-2020. Methods: After fitting in the inclusion criteria, 50 patients were signed up, 25 in each group. In group A, patients underwent surgery by using a lambda plate. In group B, patients underwent surgery by using a double plate. All this procedure was done by a researcher under the supervision of a supervisor. On follow up on each visit, patients were re-evaluated for MEP score. If MEP scores>75, then excellent to the good outcome was noted. Meanwhile, range of motion and bone union on x-rays was also evaluated. Results: In this study, the average age of the patients was 37.46±11.34 years; 32(64%). patients were male, while 18(36%). patients were females. After the 6th month, the excellent to good MEP score was noted in 23 patients (92%) of the double plate group versus the excellent to good MEP was found in 24 patients (96%) of lambda plate group, p-value=>0.999. After the sixth month, in the double plate group, the delayed union was noted in two patients (8%) of double plate group while in one patient (4%) of lambda plate group, p-value=0.261. Conclusion: This study concluded that in the management of fractures of distal humerus in adults, both lambda plate and double plate fixation are equally effective.
