Our LifeLongJoints partner AnyBody is offering the following free webinar next week:

The human body is exposed to various forces during daily activities. This presentation is about the musculoskeletal loads in the human body during typical daily activities while commuting.

Julien Groud, Application Engineer from Terrabyte, Japan will show some examples how the AnyBody Modeling System can be used to analyze loads in the human body while cycling, riding a motorbike or a train through Tokyo.

The AnyBody Team runs the webinar twice 13 May. Seating is limited, so sign up now:

1. Webinar at 9:00 Central European Time (Berlin/Paris/Rome).

2. Webinar at 23:00 Central European Time (Berlin/Paris/Rome).

We look forward to meeting you online.

Estimating edge-loading risk in patients with metal-on-metal hip resurfacing

This recording of a webcast details the method employed to investigate the contribution of patient-specific motion patterns to edge-loading risk in patients with metal-on-metal hip resurfacing arthroplasty. Fifteen subjects were recruited for motion analysis. The musculoskeletal model used a three-stage procedure. First, the patient specific joint kinematics were estimated based on a stick-figure model constructed from the standing reference frame and the estimated hip joint centres The Twente lower extremity model (TLEM) was nonlinearly morphed using radial basis functions to match the segment lengths and joint parameters of the stick-figure model. Inverse dynamic analysis was performed for the morphed TLEM model with the measured ground reaction forces as external loads and polynomial muscle recruitment criterion of power 3 to estimate muscle and joint contact forces. The distance of the hip contact force from the edge of the acetabular component during gait and sit-to-stand was used to estimate the edge-loading risk.

This webcast was released by the LifeLongJoints partner Anybody Technology and held by Stephen Mellon, University of Oxford, and Michael Skipper Andersen, Aalborg University, on 12. November, 2013
