Abstract
BackgroundClosed reduction and locked intramedullary nailing has become a common surgical method in the treatment of femoral shaft fractures. Overlap and rotation displacements can usually be corrected through the use of an orthopedic traction table. However, lateral displacement and angulation persist.MethodsIn this paper, we describe a joystick that can be used in the closed reduction of a fracture. It can correct lateral displacement and angulation, and has the advantage of multi-direction reduction. The device described in this paper includes two parallel horizontal joysticks, one vertical main joystick and four assistant rods. Moreover, there are many specific spacing holes in the two parallel horizontal joysticks and a groove structure in the vertical main joystick. When the main “H” joystick is pressed, it can adjust lateral displacements and angulation because of the lever principle. The distance between parallel horizontal joysticks and assistant rods can be adjusted to the fracture position and body mass index of different patients.ResultsThe study participants consisted of 11 males and 5 females with a mean age of 31.0 years. All participants had good closed reduction and achieved bony union without any complications such as infection, nerve injury, non-union, malunion, and limb length discrepancy. By using an “H” joystick, closed femoral shaft fracture reduction and locked intramedullary nailing becomes simpler and faster.ConclusionBased on the use of this instrument, we can easily and conveniently obtain the correct reduction situation, which leads to better surgical results. This device can be applied in the reduction of clinical femoral fractures and gradually extended to the reduction of other fractures.
Highlights
In clinical medical treatment, it is common for adults who sustain high-energy trauma to suffer from femur, tibia and humerus shaft fractures [1, 2]
Closed reduction and locked intramedullary nailing is generally accepted as a standard treatment for femoral shaft fractures because of its satisfactory union rate in a stable biomechanical environment [3,4,5]
Characteristics and application principles of the “H” joystick device Locked intramedullary nailing for the treatment of femoral shaft fractures requires careful preoperative planning and the application of multiple techniques to achieve suitable fracture reduction [11,12,13]
Summary
It is common for adults who sustain high-energy trauma to suffer from femur, tibia and humerus shaft fractures [1, 2]. During femur shaft fracture operations, through traction using an orthopedic traction table, displacement of overlap, and rotation can be basically corrected. The displacement accuracy is poor, and it requires greater exposure to X-rays, which cause unnecessary damage to both medical personnel and patients [7,8,9,10]. It is important and urgent for doctors to invent a type of device that can realize the effective reduction of femoral shaft fractures. Closed reduction and locked intramedullary nailing has become a common surgical method in the treatment of femoral shaft fractures.
