Phalangeal fractures and osteoarticular infections can be challenging injuries to manage, and their treatment is frequently complicated by deformity and stiffness. External fixation techniques have a well-established role in the treatment of these injuries. The mini-Hoffman external fixator is a particularly simple apparatus in design and in application. We report a technique of digital external fixator with a new original material developed in the service. It is an inexpensive and simple technique with good stability. The technical procedure is simple, consisting of two joints, Kirchner pins, 4mm diameter screwdrivers and a motor. Between 2001 and 2006, we used this method to treat 24 patients in a prospective study. The mean age was 35 years (range 16 to 68 years) with a male predominance, left hand predominance (14 cases), and carpenter's hand was the most frequent indication (11 cases). Mean duration of follow-up was two years (6 months to 5 years). Functional results were excellent in 12 cases and bad in six cases. Complications included a case of ischemic necrosis of the finger, two cases of secondary displacement, three cases of sepsis, two cases of algodystrophy and a case of pseudoarthrosis.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain. Disocver the latest research on single cell analysis of the gut-brain axis here.
