This shows the different articles published about shortening of the metacarpal.

Researchers	Shortening	Postulates
Jupiter and Belsky4	03 mm	Intrinsic-extrinsic imbalance
Burkhalter5		Transient extensor lag
Green and Rowland6	05 mm	No reason
Freeland et al.7	03–04 mm	Greater amount of shortening leads to rotation
Lumplesch et al.8	06 mm	Good hand function upto this level of shortening
Robert J. Strauch et al.9	02 mm shortening leads to 7° extensor lag	Cadaveric study,
MJ Meunier10	02 mm results in 8% loss in intrinsic function 55% loss when 10 mm shortening	Cadaveric study,
CK Low11	30° of dorsal angulation or 03 mm of shortening leads to decreased flexion and extension forces	Cadaveric study,
