Abstract
Observe and analyze the effect of weighted magnetic resonance imaging in the diagnosis of ankle ligament sports injury. Methods: A total of 50 patients with ankle ligament sports injuries were recruited as research subjects to conduct clinical diagnostic research. After admission, the patient first underwent MRI diagnosis of ankle joint ligament sports injury and then received surgical treatment. Based on the results of surgical treatment, the diagnostic effect of weighted magnetic resonance imaging and the detection of concurrent injuries were compared. After surgery, a total of 24 cases of ankle ligament contusion were confirmed in 50 patients, 19 cases were partially ruptured, 7 cases were completely ruptured, and 26 cases had joint effusion, tendon injuries in 17 cases, fractures in 8 cases, and talar articular cartilage lesions in 19 cases. After comparison, there was no significant difference between the results of weight-bearing magnetic resonance diagnosis and the detection rate of concurrent injuries compared with the surgical results, P> 0.05. Conclusion: The application of weight-bearing magnetic resonance imaging in the diagnosis of ankle ligament sports injury can effectively diagnose the patient's ligament injury and the type of combined injury, and has significant clinical application value.
Highlights
The largest weight-bearing flexor joint of the human body is the ankle joint
Most ankle sprains occur on the lateral side, causing damage to the lateral collateral ankle ligament (LCAL), which mainly hurts the anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) [6]–[9]
There were no contraindications to surgery, and all patients were treated by ankle joint exploration to clear microfracture
Summary
The largest weight-bearing flexor joint of the human body is the ankle joint. Because the joint surface is small, the unit area is under great pressure [1]–[3]. Shorten the imaging time, observe the performance of ankle ligaments on weight-bearing magnetic resonance, and optimize the scanning display method. The analysis of gait under normal walking or weight-bearing is mainly in the area of plantar pressure, but there is less research on the lower limb muscle and joint rotation This subject is based on the test methods such as plantar pressure test system, threedimensional force balance system, three-dimensional motion capture system, and surface electromyography. Before carrying out simulation calculations of joint moments during the walking process of single-leg and twoleg support, it is not difficult to find that the motion model in the previous chapter needs to be analyzed, and the time in the same cycle under different working conditions is selected.
