METHOD AND DEVICE FOR DIAGNOSING ANKLE JOINT INSTABILITY Russian patent published in 2019 - IPC A61B6/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, namely traumatology-orthopaedics, and can be used for diagnosis of ankle ligament injury. Device for fixing an ankle joint during computed tomography for diagnosing an ankle ligament injury involves a support pad. Support pad is rigidly fixed on ball-shaped body, wherein support platform is made with elements of fixation of patient's foot on it and possibility of patient's movement of support platform with ball-shaped body by means of sling. Method for diagnosing ligaments with ankle instability using the above device is implemented in two stages: at the first stage, intact ankle is scanned in dynamics with pre-specified ankle movements, including supination, plantar flexion and foot rotation, which the patient performs independently by the operator's command by turning the support platform using the sling in the required direction, at the second stage, the injured ankle is examined in dynamics during movements of the ankle joint, similar to the first stage, based on the results of comparison of the obtained images of the intact and injured joints, the presence of an ankle ligament injury and biomechanical instability is stated.

EFFECT: use of inventions allows providing more accurate diagnosis of fibulocalcaneal, anterior and posterior talus-fibular ligaments in severe ankle injury provided simplification of diagnosis.
