Introduction and Aims: Locking plates represent a major change in the way we stabilise fractures. The distal radius Locking Compression Plate (LCP, Synthes) theoretically enables palmar plating of dorsally comminuted and intra-articular wrist fractures. All current methods (Dorsal plates, K wires and external fixators) have considerable disadvantages. This is the first study to assess the clinical and biomechanical results of this new implant.

Method: We created a synthetic bone fracture model to compare three plates (the LCP, Buttress and Pi). We tested 24 plates, eight in each group, using the Instrom biomechanical testing machine, axially loading the model to 200 Newtons for 500 cycles. The results show significantly less displacement for the LCP plate (p< 0.05).

Results: Early clinical results are reported following a prospective study of the LCP plate to stabilise dorsally comminuted and intra-articular. The average age was 32 years. We report our results at an average follow-up of six months (range four to nine months). There were no complications. The Gartland & Werley scores were at least satisfactory in all patients and good in 75%.

Conclusion: Both our biomechanical and early clinical results support the clinical use of the palmarly applied LCP for intra-articular and dorsally comminuted wrist fractures.
