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 present invention discloses a method and system for evaluating closed reduction of femoral neck fractures based on a three-dimensional C-arm machine. Multi-dimensional imaging of the femur and the femur of the healthy side; S2: Calculate the length α of the A-line and the angle β between the projection of the B-line on the a-section plane and the B-line on the multi-dimensional imaging model; S3: The normal side obtained according to step S2 The α value α‑0 / β value β‑0, and the α value α‑1 and β value β‑1 of the fracture side were used to evaluate the effect of surgical closed reduction. The present invention uses a data-based method to make judgments, and solves the problem of inaccurate results of artificial subjective judgments in the prior art.

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...
