Role of patellar tendon on the population of muscle fiber types and the contractile properties of single glycerinated muscle fibers in quadriceps muscles of rats

Short‐term muscle atrophy caused by botulinum toxin‐A local injection impairs fracture healing in the rat femur

“…In fact, muscular atrophy caused by internal fixation and external fixation in the early stages of a fracture is not beneficial to maintaining optimum conditions for mechanical stability and stimulation. However, other similar animal models such as neurotomy, 13,14 tendon resection, 15,16 soft tissue crush, 10,17 and plaster cast fixation, 18,19 not only affect the muscles, but also affect the nerves, blood vessels, and even the entire function of limbs. Thus, interference factors cannot be excluded when exploring the relationship between a single muscle or a group of muscles and bone, especially when exploring the effect caused by changes in mechanical stability associated with muscle atrophy and dysfunction during fracture healing.…”
