Achilles tendon rupture vestigial muscle is harvested and wrapped around the Achilles tendon, increasing the strength of the repaired tendon. If the tissue quality is poor, e.g. the injury has been neglected, the surgeon might use a reinforcement mesh (collagen, Artelon or other degradable material). In percutaneous surgery, the surgeon makes several small incisions, rather than one large incision, and sews the tendon back together through the incision(s). Surgery may be delayed for about a week after the rupture to let the swelling go down. For sedentary patients and those who have vasculopathy or risks for poor healing, percutaneous surgical repair may be
Inelastic neutron scattering Inelastic neutron scattering Inelastic neutron scattering is an experimental technique commonly used in condensed matter research to study atomic and molecular motion as well as magnetic and crystal field excitations. It distinguishes itself from other neutron scattering techniques by resolving the change in kinetic energy that occurs when the collision between neutrons and the sample is an inelastic one. Results are generally communicated as the dynamic structure factor (also called inelastic scattering law) formula_1, sometimes also as the dynamic susceptibility formula_2 where the scattering vector formula_3 is the difference between incoming and outgoing wave vector, and "formula_4" is the energy
