Scaphoid fractures are the most common fracture of the carpus [1].Headless screws are favored for internal fixation in the treatment of displaced or unstable fractures, because they are embedded below the articular surface of the bone, reducing tissue irritation and immobilization. Compression plays an important role in fracture stability, maintaining gap reduction and also accelerating the healing of cancellous bone [3]. There are several types of screwsbeing used in practice and it is of clinical interest to know how different they are in generating and maintaining the compression force.
