The shoulder and hip joints form the only ball and socket joints in the body. These joints have the freest range of motion of any joint in the body â they are the only joints that can move in a full circle and rotate around their axis. However, the drawback to the ball and socket joint is that its free range of motion makes it more susceptible to dislocation than less mobile joints.
The geometry of joints refers to the orientation of joints as either plotted on stereonets and rose-diagrams or observed in rock exposures. In terms of geometry, three major types of joints, nonsystematic joints, systematic joints, and columnar jointing are recognized.Nonsystematic joints are joints that are so irregular in form, spacing, and orientation that they cannot be readily grouped into distinctive, through-going joint sets. Diagonal joints â Joints which typically occur as conjugate joint sets that trend oblique to the fold axes. 2  Strike joints â Joints which trend parallel to the strike of the axial plane of a fold. 3  Cross-strike joints â Joints which cut across the axial plane of a fold.
