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 electron tunneling spectroscopy Inelastic electron tunneling spectroscopy Inelastic electron tunneling spectroscopy (IETS) is an experimental tool for studying the vibrations of molecular adsorbates on metal oxides. It yields vibrational spectra of the adsorbates with high resolution (< 0.5 meV) and high sensitivity (< 10 molecules are required to provide a spectrum). An additional advantage is the fact that optically forbidden transitions may be observed as well. Within IETS, an oxide layer with molecules adsorbed on it is put between two metal plates. A bias voltage is applied between the two contacts. An energy diagram of the metal-oxide-metal device under bias is shown in
