Detecting early biomechanical effects of zoledronic Acid on femurs of osteoporotic female rats.

Aim. To investigate the biomechanical effects of zoledronic acid (ZA) on femurs of female osteoporotic rats after follow-up periods of 9 and 12 months. Methods.

Two-part surgical neck fractures of the humerus: mechanical analysis of the fixation with four Shanz-type threaded pins in four different assemblies.

The configuration of percutaneous pinning may affect the stability of the fixation of 2-part surgical neck fractures of the humerus. In this investigation, the mechanical properties of four different pin configurations were analyzed by use of 36 fresh-frozen swine femora as an experimental model. The bones were selected according to previously established morphologic parameters.

[Kinesiotherapy prevents shoulder pain in hemiplegic/paretic patients on sub-acute stage post-stroke].

Background: Painful shoulder is considered the most common complication of hemiplegic/parethic (H/P) stroke patients. It is a negative factor for neuromotor recovery.

Purpose: To study the effects of kinesiotherapy treatment on shoulder pain prevention, and as a secondary endpoints, to analyze muscle strength of H/P shoulder looking at basic functional active mobility.
