Modelling complex lower limb trauma

Complex fractures of the knee or hip often require surgical repair, followed by extensive rehabilitation.

To improve this rehabilitation, further understanding of surrounding joint mechanics following surgery is required, particularly the interaction between bones, bone fragments and surgically implanted metal fixations during standing and walking.

A rigid body model provides the opportunity to simulate these fractures under loads. To create the model, accurate bone geometry, joint mechanics, boundary conditions (ligament and joint properties) and external loads were required. Bone geometry was obtained through analysis of patient data from computed-tomography scans, whilst ligament and joint properties were determined from current literature. Joint reaction forces were estimated by applying musculoskeletal modelling techniques to motion capture and force platform data. The outcome of this project will contribute to a long-term goal of assisting medical professionals to make decisions regarding the rehabilitation process which are informed and specific to the patient.
