PURPOSE: Subacromial impingement syndrome (SIS) is associated with low self-reported shoulder function, impairments in shoulder strength and range of motion (ROM), and pain. It is not known how the symptomatology associated with SIS is reflected in the choice of treatment. This study compares self-reported shoulder function, shoulder strength, ROM, and pain in patients with SIS considered candidates and non-candidates for subacromial decompression (SAD). METHOD: Self-reported shoulder function (Q-DASH and SPADI), maximum isometric muscle strength in shoulder abduction (Abd-strength) and external rotation (ER-strength), active abduction ROM (Abd-ROM) and passive internal rotation ROM (IR-ROM) were measured in a consecutive cohort of patients with SIS referred to an orthopedic outpatient clinic...

Disseminated cryptococcosis caused by Cryptococcus gattii (molecular type VGI) was diagnosed in an adult free-ranging female koala (Phascolarctos cinereus). Subclinical cryptococcosis was later diagnosed in this koala's joey. In the adult koala, a pathological fracture of the tibia was associated with the bone lysis of marked focal cryptococcal osteomyelitis. Limb-sparing orthopedic intervention, in the setting of disseminated cryptococcosis, was judged to have a poor prognosis, and the adult koala was euthanized...

A new class of bio composite materials for orthopedic applications were prepared by blending polyvinyl alcohol (PVA) with certain amino acids (AA) such as glycine, lysine and phenyl alanine followed by in-situ cross-linking with citric acid (CT). CT cross-linked PVA offers sufficient chemical, thermal, and morphological stability by establishing intermolecular interaction. These biocomposite films were characterized for mechanical and thermal behaviors as well as analyzed through SEM, TGA and AFM studies. Zwitterionic characteristics of AA create cell-adhesive hydrophilic domains that act as potential cell-adhesion sites and facilitate osteointegration...

BACKGROUND: Surgical energy injuries are an underappreciated phenomenon. Improper use of surgical energy or poor attention to patient safety can result in operating room fires, tissue injuries, and interferences with other electronic devices, while rare complications can be devastatingly severe. Despite this, there is no current standard requirement for educating surgeons on the safe use of energy-based devices or evaluation of electrosurgery (ES) education in residency training, credentialing, or practice...
