1. Introduction
In orthopedic surgery, locking compression plates (LCP) are commonly used to stabilize fractured bone parts together. LCPs are generally manufactured with combi-holes that aim to accommodate two types of screws: locking and compression screws [1]. The choice of screws allows orthopedists to customize their installation method to balance compression and locking capability. This balance is necessary to provide angular stability and to limitthe contact with the bone to preserve the blood supply and the tissue viability. Compression is known to produce the strain needed for the bone during the healing process of reconstruction [1]. Even though LCPs show uncontradicted advantages for healing fractured bones, their mechanical stability is technically difficult to maintain [2]. In 2003, a study involving 130 fractures repaired with a LCPshowed 27 complications, with 18 of them requiring a second intervention [3]. The most common complications were nonunion ofthe bone, loosening ofthe implant, breakage ofthe implant or an additional bone fracture. The objective ofthis study is to understand the failure mechanism of a specific LCP that failed prematurely. The studied systemis composed of a LCPfixed to a broken femur using bothlocking and compressionscrews.Apicture ofthe broken implant is shown in Fig. 1. The distal extremity is situated closer to the knee and on the opposite side, the proximal extremity is closer to the hip. The failure analysis of the LCP was performed in 3 steps: material characterization (Section 4.1), fractographic analysis (Section4.2), andpreliminaryfiniteelement analysis (FEA) ofthe stresses seenbythe implant(Section5). A discussion explaining the failure mechanism and the root causes of failure is proposed in Sections 6 and 7.
