Overview of our database on morphological data (shoulder)

last modification date October 10, 2003

 

overview of modifications made to this site and the listed data files

 

The data base consists of three sections: the VU-study,  the Mayo-study and the Leiden study. Each section comprises an introduction - link and links to the individual data files. Not all data are available yet. Please feel free to send us your reactions or questions about available or unlisted data.

VU-study (1988 - 1996)

 

Introduction

 

Inertial data

Anatomical landmarks

(both left and right shoulders)

Ligaments

Origins and insertions for the conoid and trapezoid ligaments expressed in the global coordinate system. Note: the length of each ligament is not actually known and it is likely that some were buckled when measured.

collum humeri  modeled as a cylinder

 

Proportional elements

Origins & Insertions expressed as t-values

Mapping of Origins to Insertions

Data file for shoulder and elbow model

specimen_r2 : this data file is a combination of the data from specimen r2 of the VU study and k4 of the Mayo study. In general, al shoulder data stem from r2, whereas all elbow data are from k4.
