Salicylic acid (SA)-eluting bone regeneration scaffolds with interconnected porosity and local and sustained SA release.

In previous work, we observed that localized and sustained delivery of an anti-inflammatory drug, salicylic acid (SA), via a SA-based polymer (SAP) powder significantly enhanced diabetic bone regeneration through long-term mitigation of local inflammation. In this study, SAP was formulated into uniform microspheres and then sintered into a scaffold with an interconnected porous structure and modulus suitable for bone regeneration. The SAP scaffolds have ∼45% SA loading, which is the highest among drug-eluting bone regeneration scaffolds to-date.

Clinical anatomy aspects of functional 3D training -- case study.

Introduction: Functional 3D training originating in rehabilitation and physiotherapy routines, is modelled on the basis of a patient's functional impairment and muscle function test results. 3-D functional rehabilitation comprises two key components. The first is three-dimensional movements of the body and the second is restoration of function, The aim of 3D training is not only to improve physical fitness and muscular coordination, it is recommended for all age groups regardless of health status.

Associations among hip and shoulder range of motion and shoulder injury in professional baseball players.

Context: The overhead throwing motion is complex, and restrictions in range of motion (ROM) at the hip may place additional demands on the shoulder that lead to injury. However, the relationship between hip and shoulder ROM in athletes with and without a history of shoulder injury is unknown.

Objective: To (1) determine if differences exist in hip and shoulder ROM between professional baseball players with a history of shoulder injury and those with no history of shoulder injury and (2) assess relationships between hip and shoulder ROM in these players.
