With respect to the shoulder, latissimus dorsi is a two-joint muscle, crossing both the
glenohumeral and scapulo-thoracic joints and so, all of its force would be available for action on
the humerus, with an additional effect on the scapula. Its fibres do not pass in a straight line to the
humerus. Rather, they wrap around the posterior chest wall, and their orientation is governed
largely by the position of the arm. Their line of action is not, for practical purposes, defined by the
caudal attachments. Rather, it would be a line passing from the humerus tangential to the chest
wall. To model the latissimus dorsi, therefore, would require specification of the position of the
humerus, and a knowledge of the size and curvature of the chest wall. These issues were not
addressed in the present study, although they have been examined in detail by Hogfors et al. [12].
However, valid estima- The iliac fibres have the most direct and most extensive action. They span
the entire lumbar spine and, therefore, act on every segment. Since they are orientated steeply,
most of their action is expressed as a sagittal vector (Table 2). Endowed with a moment arm of 4
cm, these fibres might provide an average extensor moment of 1.3Nm, with a range of 0.52.8Nm
(Table 3 )..
