[Medial migration of a Hansson hook-pin after femoral neck fracture].

Medial migration of a LIH (Lars Ingvar Hansson) hookpin is a very rare complication to internal fixation of hip fractures. We report a case of medial migration of an LIH hook-pin into the acetabulum. The importance of using the correct length hook-pin and ensuring that the base of the hook-pin is outside the lateral cortex of the femur is stressed.
