Background
Femoral shaft fractures account for about 6% of total body fractures, and children under 10 years old are more frequent, and are a common and frequently encountered disease of pediatric fractures. The thighbone is a single skeleton of thigh, and the muscle is attached abundantly, and is powerful, appears shortening displacement and angulation deformity easily, therefore needs timely treatment. The existing common treatment measures mainly comprise the following modes: 1. splints or plaster external fixation; 2. a suspension skin traction method; 3. a horizontal skin traction method; 4. bone distraction; 5. cutting and resetting, and performing steel plate internal fixation; 6. incision reduction or closed reduction, and external fixation is added to the internal fixation of the elastic intramedullary nail. However, the existing therapeutic measures have some defects, and the expected value of the curative effect requirement of the guardian cannot be met more and more. The method comprises the following steps:
1. the external fixation method of the splint or the plaster has the defects that the splint or the plaster is used for external fixation after reset: (1) Poor fixing reliability and easy fracture re-displacement; (2) The skin of the children is delicate, and skin maceration and even pressure sores are easy to occur; (3) fixation of the joint, which is prone to joint stiffness; (4) The management is unchanged, the regulation is carried out at any time, the child is not easy to tolerate, the unacceptable alignment and alignment relation is easy to appear, and even the fracture deformity healing appears.
2. The suspension skin traction method is suitable for children patients under 3-4 years old, and has the following defects: (1) The skin of the children is delicate, and skin maceration and even pressure sores are easy to occur; (2) The traction force is unreliable, shortening displacement is easy to occur, the two lower limbs are not equal in length after fracture healing, and the equal length can be basically recovered about one year after injury, but the child patient guardian is generally not easy to accept, and the medical dispute hidden trouble exists; (3) The photo is difficult, and the alignment and growth conditions of fracture and the like cannot be dynamically observed; (4) Traction comfort is poor, and children patients often cannot tolerate the traction comfort for a long time.
3. The horizontal skin traction method is suitable for children aged 5-8 years, and has the following defects: (1) there is a risk of skin maceration and pressure sores; (2) The femur can not be matched with the physiological curvature of the femur, angulation deformity is easy to occur, and the local splint is also needed to assist; (3) Also has insufficient traction force, and limb shortening easily occurs; (4) The photo is difficult, and the alignment and growth conditions of fracture and the like cannot be dynamically observed; (5) Poor traction comfort, and the child patients often cannot tolerate the traction comfort for a long time; (6) the swelling of the injured limb of the horizontal traction subsides slowly.
4. Bone distraction, suitable for patients aged 8-12, has drawbacks: (1) there is some trauma or even risk of damaging the epiphysis; (2) If the traction is excessive, the bone is possibly disconnected, and even the operation is needed for bone grafting; (3) The photo is difficult, and the alignment and growth conditions of fracture and the like cannot be dynamically observed; (4) Traction comfort is poor, and children patients often cannot tolerate the traction comfort for a long time.
5. Cut and reset, steel sheet internal fixation art, reset that can be better and good fixed, infant is also comfortable, the management of being convenient for, defect that exists: (1) There are risks of anesthesia, infection, damage to important nerve vessels, internal fixation loosening and displacement, etc.; (2) the surgical operation is needed to be fixed and taken out again; (3) Scar is left, which has a certain influence on the psychological or selective operation of patients; (5) at least two operations, the economic burden is high.
6. Incision reduction or closed reduction, elastic intramedullary nail internal fixation and external fixation are novel treatment schemes, have small wounds, can improve alignment of fracture, and still have the following defects: (1) the radio frequency is more in operation; (2) There are risks of anesthesia, infection, damage to important nerve vessels, internal fixation loosening and displacement, etc.; (3) the internal fixation is taken out by re-operation; (4) Scar is left, which has a certain influence on the psychological or selective operation of patients; (5) at least two operations, the economic burden is high; (6) The primary hospitals generally have lower proficiency in surgery and are less developed.
