Microneurovascular anatomy of the peroneus brevis muscle in the NZW-rabbit: a new model for free functional muscle transplantation.
This study introduces the peroneus brevis muscle of the NZW-rabbit as a new model for free functional muscle transplantation. The muscle originates from the lateral aspect of the knee joint and inserts on the 5th metatarsal with a circumscript tendon. It can be harvested with a 7 cm long motor nerve branch. In a series of 22 animals divided in two groups with a body weight of 3.19 +/- 0.30 kg and 4.81 +/- 0.38 kg respectively, vessel diameter of the supplying artery was found to be 0.3-0.35 mm in group one and 0.40-0.45 mm in group two, the two concomitant veins were 1.1-1.4 mm in diameter in the first group and 1.2-1.6 mm in the second group. Histomorphometric analysis stained with NADH showed 3.67 +/- 3.21% type I fibers, 25.41 +/- 7.87% type IIa fibers, and 70.93 +/- 9.12% type IIb/d fibers.
