Analysis of shoulder motion with inertial sensors in Poland syndrome patients.

Purpose: Poland syndrome is a congenital malformation characterized by agenesis or hypoplasia of pectoralis muscles. There is a limited literature on how the anatomic anomalies of PS may impact the movement of the shoulder. This study analyzes the effects of absence of the pectoralis muscles on the shoulder kinematic.

Fiber-optic gyroscope for rotational seismic ground motion monitoring of the Campi Flegrei volcanic area.

The real-time monitoring of densely populated areas with high seismic and volcanic risk is of crucial importance for the safety of people and infrastructures. When an earthquake occurs, the Earth surface experiences both translational and rotational motions. The latter are usually not monitored, but their measurement and characterization are essential for a full description of the ground motion.

All-fiber high-resolution incoherent broadband spectrometer.

Portable optical spectrometers are crucial devices for bio-chemical sensing and spectroscopic applications whereby robust, compact and cost-effective set-ups are desirable. However, existing miniaturized instruments typically struggle to achieve broad wavelength operation and high spectral resolution at the same time. Here, an all-fiber optical spectrometer based on two cascaded Bragg gratings is devised and demonstrated, showing a record resolution and a wavelength span-to-resolution ratio larger than that of most miniature broadband spectrometers reported to date.

High satisfaction rate and range of motion can be expected in frozen shoulder after awake manipulation with brachial plexus block.

Background: Adhesive capsulitis (AC) is a disease of the glenohumeral joint that is characterized by pain and both passive and active global stiffness with a slow and insidious onset. The disease can occur spontaneously (primary AC) or it can be secondary to other comorbidities, surgery, or trauma, such as fracture or dislocation. Multiple treatment approaches have been suggested: intra-articular steroid injection, physical therapy, manipulation under total anesthesia, and arthroscopic or open surgery.

Great tuberosity fixation does not affect healing and clinical outcomes in RSA performed in proximal humeral fractures in elderly patients.

Purpose: Aims of our study were to define whether the great tuberosity (GT) positioning fixation in reverse shoulder arthroplasty (RSA) after proximal humeral fracture (PHF) could predict tuberosity healing and its impact on clinical outcomes.

Methods: We enrolled 59 patients treated with cementless reverse shoulder arthroplasty after PHF in our institute between 2012 and 2018. The mean follow-up was 57 months (± 23.
