Fig. 3From: Anatomy and histomorphology of the flexor digitorum profundus enthesis: functional implications for tissue engineering and surgeryFDP Footprint Shape and Size. Complete set of unstained FDP footprints on stained DPs, with each binary ‘mask’ footprint below, showing trapezoidal footprint shape. Scale bars 2 mm. b) Comparison of footprint trapezoid left and right internal angles. Non-significant (ns) differences suggest a symmetrical shape across the vertical axis. c) Footprint surface area, compared within sex and finger categories. The little finger is the principle source of significant size differences. Mean ± standard error. *p < 0.05, **p < 0.01, ***p < 0.001Back to article page
