Chest wall soft tissue thickness is associated with humeral shaft non-union: A radiographic study.

Background: Anecdotally, upper truncal obesity and large breasts have often been associated with inferior outcomes from non-operative management of diaphyseal humerus fractures. However, this assertion is without basis in the literature.

Aims: To produce radiographic measurements of chest wall soft tissue thickness (STT) and determine association with non-union in diaphyseal humerus fractures.

Arthroscopically induced posterior capsular fibrosis to correct symptomatic hyperextension of the knee.

We present a technical note on 2 patients with post-traumatic symptomatic hyperextension of the knee treated with a new arthroscopic technique. Both patients were of similar ages with similar injuries resulting in an excess of hyperextension at the knee with resulting instability and pain. Both patients had not improved with a variety of nonoperative measures and 1 attempt each at simple arthroscopic debridement of the damaged tissue.

A biomechanical comparison of plate configuration in distal humerus fractures.

Objectives: Our aim was to test the hypothesis that two plates placed parallel to each other are stronger and stiffer than plates placed perpendicular to each other for fixation of a distal humerus fracture model.

Methods: We created an artificial distal humeral fracture model by osteotomizing two groups of identical epoxy resin humera. Screw and plate constructs were built to mimic osteosynthesis.

Soft tissue impact characterisation kit (STICK) for ex situ investigation of heart rhythm responses to acute mechanical stimulation.

Both mechanical induction and mechanical termination of arrhythmias have been reported in man. Examples include pre-cordial impacts by sports implements (baseballs, pucks) that can trigger arrhythmias, including ventricular fibrillation, or via the so-called pre-cordial thump, used as an emergency resuscitation measure to convert arrhythmias to normal sinus node rhythm. These interventions have been partially reproduced in experimental studies on whole animals.
