Evaluating lower limb kinematics and pathology with dynamic CT.Evaluating musculoskeletal conditions of the lower limb and understanding the pathophysiology of complex bone kinematics is challenging.  Dynamic CT (4D-CT) is an emerging alternative that combines high spatial and temporal resolution, with an increased availability in clinical practice.

Dynamic CT (4D-CT) is an emerging alternative that combines high spatial and temporal resolution, with an increased availability in clinical practice.  4D-CT allows simultaneous visualization of bone morphology and joint kinematics.  In the lower limb, 4D-CT has been used to diagnose femoroacetabular impingement, patellofemoral, ankle and subtalar joint instability, or reduced range of motion.  4D-CT has also been used to demonstrate the effect of surgery, mainly on patellar instability.  4D-CT will need further research and validation before it can be widely used in clinical practice.
