Description

Technical Field

[0001] The present application belongs to the field of hip impingement syndrome, and in particular, relates to a preoperative planning method, device, equipment and computer-readable storage medium for hip impingement syndrome. Background Art

[0002] Femoroacetabular Impingement (FAI) is a common hip joint disease, especially in young athletes and middle-aged and elderly people. The syndrome is mainly caused by abnormal contact and friction between the femoral head and acetabulum, resulting in damage to the articular cartilage and acetabular labrum, causing hip pain and limited mobility. If not treated in time, it may further develop into hip osteoarthritis.

[0003] Surgical intervention is one of the more common and effective means of treating hip impingement syndrome. Through surgery, doctors can remove the abnormal bone structure that causes impingement and repair damaged soft tissue. However, due to the complex anatomical structure and high functional requirements of the hip joint, detailed preoperative planning is crucial to the success of the operation. Traditional preoperative planning is based on the doctor's own experience. Due to the different experiences of each doctor, it is impossible to accurately determine the preoperative planning plan, which leads to the inability to accurately remove the lesion during the operation.

[0004] Therefore, how to more accurately determine the preoperative planning plan and then accurately remove the lesion during the operation is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] The embodiments of the present application provide a preoperative planning method, device, equipment and computer-readable storage medium for hip impingement syndrome, which can more accurately determine the preoperative planning plan and thus accurately remove the lesion during the operation.

[0006] In a first aspect, an embodiment of the present application provides a preoperative planning method for hip impingement syndrome, comprising:

[0007] Obtain a CT image of the patient's hip joint;

[0008] Segment and 3D reconstruct the hip joint CT image to obtain a 3D model of the hip joint;

[0009] Based on the three-dimensional model of the hip joint, different movement postures of the hip joint are simulated to obtain movement simulation results; wherein, the simulation of different movement postures of the hip joint includes simulation of hip flexion and extension, flexion, abduction, internal rotation and external rotation;

[0010] According to the motion simulation results, the lesion type is determined;

[0011] Determine the preoperative planning plan based on the type of lesion.

[0012] Optionally, based on the three-dimensional model of the hip joint, different movement postures of the hip joint are simulated to obtain movement simulation results, including:

[0014] Through simulation, the mechanical state, contact pressure distribution and impact area of ​​the hip joint at various positions during these movements are obtained.

[0015] Optionally, the lesion type is determined based on the motion simulation results, including:

[0016] By analyzing the results of motion simulation, the anatomical abnormalities and lesion locations that cause hip impingement syndrome are identified;

[0017] Determine the type of lesion based on the anatomical abnormality and the location of the lesion; the lesion type includes cam type, clamp type, or mixed type lesion;

[0018] Among them, the cam type occurs at the junction of the femoral head and the neck. Due to the abnormal shape of the femoral head, a non-spherical bulge is formed in the femoral head and neck area. When the hip joint moves, this bulge will come into abnormal contact with the edge of the acetabulum, especially when the hip joint is flexed or rotated, resulting in wear or damage to the articular cartilage and acetabular labrum.

[0019] The pincer type is caused by excessive coverage of the acetabulum, resulting in excessive contact between the acetabular rim and the femoral head. In this case, the bone of the acetabular rim or labrum will squeeze the femoral head during hip movement, especially during abduction or rotation of the hip, causing damage to the labrum.

[0020] The mixed type is a combination of the cam and pincer types, with the patient having both cam and pincer anatomical abnormalities.

[0021] Optionally, determine the preoperative planning plan based on the type of lesion, including:

[0022] When the lesion type is cam-type, the non-spherical protrusion at the junction of the femoral head and neck is accurately located;

[0023] Measure the size and shape of non-spherical protrusions;

[0024] Determine the area where the non-spherical protrusion contacts the acetabular rim according to the position, size and shape of the non-spherical protrusion;

[0025] The amount of protruding bone that needs to be removed is determined based on the area where the non-spherical protrusion contacts the acetabular rim;

[0026] According to the protruding bone that needs to be removed, plan the starting position, end position, resection depth and resection steps of the bone resection.

[0027] Optionally, determine the preoperative planning plan based on the type of lesion, including:

[0028] When the lesion type is clamp-type, the acetabular inclination angle, coverage depth, and contact between the acetabular edge and the femoral head are measured based on the three-dimensional model of the hip joint to determine the scope and severity of acetabular over-coverage;

[0029] According to the extent and severity of acetabular over-coverage, the starting position, end position, resection depth and resection steps of the excessive bone resection of the acetabular edge are planned.

[0030] Optionally, after acquiring the patient's hip joint CT image, the hip joint CT image is preprocessed, including:

[0031] Use Gaussian filtering, mean filtering or median filtering to filter noise and smooth the hip joint CT images;

[0032] Image enhancement was performed on the hip joint CT images after noise filtering and image smoothing.

[0033] Optionally, the hip joint CT image is segmented and 3D reconstructed to obtain a 3D model of the hip joint, including:

[0034] Perform threshold segmentation on the region of interest (ROI) in the hip joint CT image to obtain the segmentation result;

[0035] Perform boundary smoothing and hole filling on the segmentation results;

[0036] The segmentation results after boundary smoothing and hole filling are subjected to volume rendering and surface reconstruction to obtain a three-dimensional model of the hip joint.

[0037] In a second aspect, an embodiment of the present application provides a preoperative planning device for hip impingement syndrome, comprising:

[0038] An image acquisition module, used for acquiring a CT image of a patient's hip joint;

[0039] A three-dimensional reconstruction module is used to segment and three-dimensionally reconstruct the hip joint CT image to obtain a three-dimensional model of the hip joint;

[0041] A lesion determination module is used to determine the lesion type according to the motion simulation results;

[0042] The planning scheme determination module is used to determine the preoperative planning scheme according to the lesion type.

[0043] In a third aspect, an embodiment of the present application provides an electronic device, the electronic device comprising: a processor and a memory storing computer program instructions;

[0044] When the processor executes the computer program instructions, a preoperative planning method for hip impingement syndrome is implemented.

[0045] In a fourth aspect, an embodiment of the present application provides a computer-readable storage medium having computer program instructions stored thereon, which, when executed by a processor, implement a preoperative planning method for hip impingement syndrome.

[0046] The preoperative planning method, device, equipment and computer-readable storage medium for hip impingement syndrome of the embodiments of the present application can more accurately determine the preoperative planning plan and thus accurately remove the lesion during the operation.

[0047] The preoperative planning approach for hip impingement syndrome includes:

[0048] Obtain a CT image of the patient's hip joint;

[0049] Segment and 3D reconstruct the hip joint CT image to obtain a 3D model of the hip joint;
