Parallel-fibered muscles transplanted with neurovascular repair into bipennate muscle sites in rabbits
Experiments were performed on 20 New Zealand White male rabbits. Our hypotheses were that (1) latissimus dorsi (LTD) muscles transplanted into the site of a bipennate rectus femoris (RFM) muscle with neurovascular repair would retain their parallel-fibered structure and (2) the parallel-fibered stru...

| description | Experiments were performed on 20 New Zealand White male rabbits. Our hypotheses were that (1) latissimus dorsi (LTD) muscles transplanted into the site of a bipennate rectus femoris (RFM) muscle with neurovascular repair would retain their parallel-fibered structure and (2) the parallel-fibered structure of latissimus dorsi grafts would reduce their total fiber cross-sectional area and adversely affect force development relative to that of bipennate rectus femoris grafts and muscles. Compared with their respective donor muscles, 120 to 150 days after grafting, latissimus dorsi and rectus femoris grafts showed no change in the number of fibers and a decrease in the mean single-fiber cross-sectional area to approximately 70 percent. The latissimus dorsi grafts, which remained parallel-fibered, developed maximum forces 34 and 23 percent of the values for fully activated rectus femoris grafts and muscles, respectively. The deficit in the maximum force of the latissimus dorsi grafts resulted primarily from the smaller total-fiber cross-sectional area as a result of the parallel-fibered structure. |
