Spectroscopic characterization of tissue and liquids during arthroscopic radio-frequency ablation.

Purpose: Radio-frequency ablation devices generating a local plasma are widely used as a safe and precise tool for tissue removal in arthroscopic surgeries. During this process, specific light emissions are generated. The aim of this study was to investigate the diagnostic potential of optical emission spectrum analysis for liquid and tissue characterization.

Surgical hip dislocation for osteochondral transplantation as a salvage procedure for a femoral head impaction fracture.

Obturator anterior hip dislocation is very rare. Poor results are described in patients with additional large transchondral fractures and treatment of these injuries remains challenging. Appropriate treatment recommendations are missing in the literature.

Influence of test temperature and test speed on the mechanical strength of absorbable suture anchors.

Purpose: Absorbable implant materials offer various advantages but are mechanically far weaker than metals. Despite known temperature dependence of the biomechanical properties of these materials, mechanical testing has almost exclusively been performed at room temperature in the literature. In this study, the difference in mechanical performance at room and body temperature was assessed in vitro at different test speeds.
