[Three-column plate internal fixation for the treatment of complex tibial plateau fracture through antero-midline and postero-medial approaches].

Objective: To study technique and clinical therapeutic effects of internal fixation with three-column plates for the treatment of complex tibial plateau fractures through antero-midline and postero-medial approaches.

Methods: From January 2010 to December 2012, 28 patients with complex tibial plateau fractures were treated with internal fixation using three-column plates through antero-midline and postero-medial approaches. There were 17 males and 11 females, with an average age of 45.

[Research on LC-based spectral imaging system for visible band].

LC-based tunable filter with large aperture has been developed utilizing the effect of electric controlled birefringence. Spectral test indicated that this filter can operate in the visible band with an average 20 nm FWHM. A small scale spectral imaging system was established based on this tunable filter.
