Embodiment Construction

[0034] This embodiment is suitable for patients with femoral neck fracture on one side and healthy femoral neck on the other side. Although under normal circumstances, the healthy femurs on both sides are not exactly the same, but after one side of the femoral neck is fractured, the femoral neck on the healthy side can be used as a standard reference to facilitate the evaluation of the effect of closed reduction.

[0035] Describe technical scheme of the present invention in further detail below in conjunction with accompanying drawing: as figure 1 As shown, the closed reduction evaluation method of femoral neck fracture based on the three-dimensional C-arm machine includes the following steps:

[0036] S1: After closed reduction, the femur on the fractured side of the femoral neck and the femur on the healthy side were multidimensionally imaged using a three-dimensional C-arm machine;

[0037] S2: Perform the following operations on the femoral multidimensional imaging image...

Abstract

The invention discloses a femoral neck fracture closed reduction evaluation method and a system based on a three-dimensional C-type arm machine. The method comprises the following steps of S1, after closed reduction is performed in an operation, using the three-dimensional C-type arm machine to carry out multi-dimensional imaging on a femur of a femoral neck fracture side after the closed reduction and a femur of a health side; S2, calculating an A line length alpha and an included angle beta of a projection of a B line on an alpha tangent plane and the B line on a model of multi-dimensional imaging; and S3, according to an alpha value alpha-0/a beta value beta-0 of a normal side, and an alpha value alpha-1 and a beta value beta-1 of a fracture side which are acquired in the step S2, evaluating an operation closed reduction effect. In the invention, a data-based mode is used to determine, and a problem that a result of a personal subjective determination is not accurate in the prior art is solved.

Description

technical field [0001] The invention relates to a closed reduction evaluation method and system for femoral neck fractures based on a three-dimensional C-arm machine. Background technique [0002] Femoral neck fracture refers to the fracture of the femoral neck caused by osteoporosis, degeneration of the muscles around the hip, unresponsiveness or severe trauma. The blood supply to this part is poor. If the fracture treatment is not timely or appropriate, it will lead to fracture nonunion or concurrent avascular necrosis of the femoral head and traumatic arthritis, which will seriously affect life. [0003] The morphology of femoral neck fractures can be divided into embedded type and dislocation type. The fracture line of these two types of femoral neck fractures can appear as a compact line and / or a lucent line. The dense fracture line indicates that the bone trabeculae of the two fracture ends overlap and intercalate, while the clear fracture line indicates that the two...
