Early results of a posterolateral polyaxial angle-stable plate for tibiotalocalcaneal arthrodesis.

Tibiotalocalcaneal arthrodesis is still considered the reference standard therapy for salvage of severe osteoarthritic deformities of the ankle and hindfoot. Because of the unique anatomy and biomechanics of the ankle, even minor injuries can progress to end-stage osteoarthritis over time. This can be debilitating to patients' general health and physiologic ambulation.

Hip subluxation as a complication of arthroscopic debridement.

Labral lesions are a common indication for hip arthroscopy (HA). We report a case of a 49-year-old woman who underwent HA for a long ventrolateral labral tear and exostosis of the lateral acetabular rim. She also presented with moderate hip dysplasia.

Excitation and inhibition jointly regulate cortical reorganization in adult rats.

The primary somatosensory cortex (SI) retains its capability for cortical reorganization after injury or differential use into adulthood. The plastic response of SI cells to peripheral stimulation is characterized by extension of cortical representations accompanied by changes of the receptive field size of neurons. We used intracortical microstimulation that is known to enforce local, intracortical synchronous activity, to induce cortical reorganization and applied immunohistochemical methods in the same individual animals to investigate how plasticity in the cortical topographic maps is linked to changes in the spatial layout of the inhibitory and excitatory neurotransmitter systems.
