Unlabelled: Malunion, nonunion, congenital abnormalities, and osteometabolic diseases are the main causes of long bone deformities. Although the exact incidence is unclear, it is estimated that about 10% of all fractures have some complication in terms of fracture-healing. In addition to the aesthetic impact, malunions generally substantially impair function and quality of life.

Design: Retrospective case series.
Setting: University hospital.
Background: Z-effect and reverse Z-effect are complications that arise from the surgical treatment of pertrochanteric fractures of the femur with proximal femoral nails (PFN) comprising two interlocking head screws. Such complications are induced by the migration of screws in opposite directions, which may lead to failure of the osteosynthesis.
Findings: The paper describes three cases of pertrochanteric fractures that were treated with PFN with two interlocking screws that evolved to either Z-effect or reverse Z-effect.
