Microsurgery in Motion: An Objective Assessment of Microsurgical Skill and Efficiency.

Background:  High levels of precision, as well as controlled, efficient motions, are important components of microsurgical technique and success. An accurate and objective means of skill assessment is lacking in resident microsurgical education. Here we employ three-dimensional, real-time motion-tracking technology to analyze hand and instrument motion during microsurgical anastomoses.

Vibration Control of Flexible Launch Vehicles Using Fiber Bragg Grating Sensor Arrays.

The effects of mechanical vibrations on control system stability could be significant in control systems designed on the assumption of rigid-body dynamics, such as launch vehicles. Vibrational loads can also cause damage to launch vehicles due to fatigue or excitation of structural resonances. This paper investigates a method to control structural vibrations in real time using a finite number of strain measurements from a fiber Bragg grating (FBG) sensor array.

External Validation of a Predictive Score for Fracture-Related Infections in Orthopedic Trauma Surgery.

Background: The purpose of this study was to externally validate a predictive score for fracture-related infections, establishing generalizability for absolute and relative risk of infection in the setting of orthopedic fracture surgery.

Materials And Methods: This was a retrospective, case-control study performed at a level I academic trauma center that included 147 patients with fracture-related infection in the study group and 300 control patients. We analyzed the same 8 independent predictors of fracture-related infection cited by a previous study.

Supportive care interventions in metastatic bone disease: scoping review.

Background: Patients with secondary metastatic involvement of the musculoskeletal system due to primary cancers are a rapidly growing population with significant risks for health-related end-of-life morbidities. In particular, bone metastases or metastatic bone disease (MBD) imparts significant adversity to remaining quality of life. No rigorous review of clinical trials on the use of supportive care interventions for MBD has been conducted.
