Abstract

The invention relates to the technical field of medical information processing, in particular to a method and system for determining the thighbone length in hip replacement arthroplasty, and the method comprises the steps: obtaining a normal leg CT image obtained by carrying out CT scanning on the leg part of a normal leg of a patient, and determining the length of the leg part of the patient according to the normal leg CT image so as to determine the length of a femur neck prosthesis; performing spatial positioning on the highest point of the femoral ball and the osteotomy surface of the leg implanted with the femoral neck prosthesis by adopting an optical sensor so as to determine a first relative distance between the highest point of the femoral ball and the osteotomy surface in real time; adopting an optical sensor to conduct spatial positioning on the anterior superior spine of the leg where the femoral neck prosthesis is implanted and the planta pedis so as to determine the second relative distance between the anterior superior spine and the planta pedis in real time; finally, the length of the femoral head prosthesis implanted into the leg of the patient is determined, so that the second relative distance and the length of the leg of the patient are within the allowable deviation range, and the accuracy and speed of the length of the femoral neck in hip replacement can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical information processing, in particular to a method and system for determining the length of a femur in hip joint replacement. Background technique [0002] Total hip arthroplasty (total-hip-arthroplasty, THA) is the use of surgical methods to replace the articular surface, femoral head, and acetabulum damaged by disease or injury with an artificial hip prosthesis, so as to remove the lesion, eliminate pain, and restore The original function of the joint and other effects are widely used in the treatment of hip joint diseases such as joint ankylosis, femoral head necrosis, osteoarthritis, and rheumatoid arthritis. Human bone mass declines with age. The elderly are a high-risk population for hip joint diseases, and total hip replacement is one of the common methods for treating hip joint-related diseases. As China's aging population increases, the demand for artificial total hip replacement will inc...
