139 FUNCTIONAL MOTOR RECOVERY OF ANGIOGENESIS OF NERVE ALLOGRAFTS 7 Wet muscle mass At 12 weeks, the autograft muscle mass (66.6 ± 2.1% of the contralateral tibial muscle) was superior in comparison to allografts (57.6 ± 2.5%, P=0.01) and the SIEF group (56.0 ± 1.4%, P<0.01). At 16 weeks, autografts measured 70.8 ± 1.8%, allografts 65.9 ± 3.4% and SIEF 61.8 ± 1.5%. The autograft was only significantly superior to the SIEF group (P<0.05) (Figure 2). Figure 2. Wet muscle mass of the tibial anterior muscle at 12 and 16 weeks for the autograft, al - lograft and the allograft wrapped with a superficial inferior epigastric artery fascial (SIEF) flap. Results are expressed as a percentage of the experimental left side to the unoperated right side (L/R Ratio) and are given as the mean ± SEM. *Indicates significance at P<0.05, ** P<0.01). N=10 per group. SEM: Standard error of the mean. Ankle contracture angle At 12 weeks, the ankle contracture angle measured 81.6 ± 3.1% in the autograft group, 72.7 ± 1.2% in allografts and 75.8 ± 2.1% in SIEF. Autografts had a significant larger angle compared to allografts (P<0.05). At 16 weeks, all groups normalized to similar results with around 80% recovery.
