Proximal femoral nail anti-rotation (PFNA) with a lag screw that is shaped like a spiral blade shape is an orthopedic implant to fix trochanteric fractures of the proximal femur. In addition the reason of the biomechanical advantages, PFNA widely been used recently. We report an 83-year-old man with excessive sliding of the helical blade and a femoral neck fracture after AO/OTA type A2 intertrochanteric fracture, which was fixed with a PFNA.

Unstable fractures of the proximal humerus should be treated with precise reduction and stable fixation, and early joint motion should be permitted. But stable fixation of the proximal humerus is frequently difficult to obtain in older patients due to osteoporosis and fracture comminution. We treated one case of a segmental comminuted fracture of the proximal humerus with severe osteoporosis with a method of inlay fibular autograft and fixation with a helical locking compression plate (LCP). Stable fixation was obtained, so early motion of the shoulder joint was permitted. The fracture was healed in 12 weeks after the operation without loss of fixation and there were no problems at the donor site of the fibula. Functional recovery of the shoulder was satisfactory. The result of Neer's functional score was 87 points (satisfactory) and Constant score was 83 points.

PURPOSE This study demonstrates the effectiveness of the blade plate as an implant for the operative management of proximal tibial fractures. MATERIALS AND METHODS Twelve proximal tibial fractures (AO classification, 10 type A and 2 type C) were treated by direct or indirect reduction and condylar blade plate fixation. The condylar blade plate was fixed on the anteromedial surface of the proximal tibia and cancellous bone graft was performed in 4 fractures with severe cortical comminution or bone defect in early cases. At the final follow-up assessment, the patients were evaluated as to subjective symptoms, objective findings, and radiographic findings. RESULTS All fractures were healed in an average of 13.2 weeks (range, 9.0 to 25.0 weeks). There were 3 major complications of a delayed union, a 6-degree varus malunion, and a reduced range of motion of the knee related with associated multiple fractures of the ipsilateral lower limb, but there were no soft tissue problems, loss of fixation, infection, nonunion, and traumatic arthritis. A few patients complained a prominence of the plate on the anteromedial side of the proximal tibia. CONCLUSION Blade plate fixation is a reliable method of stable fixation to obtain good results for proximal tibial fractures by early rehabilitation and good fracture healing, particularly in patients with osteoporosis and cortical comminution.
