[Arthroscopy-assisted glenohumeral arthrodesis: a case of uncontrollable shoulder instability]. / Arthroskopisch assistierte Arthrodese des Glenohumeralgelenks: Fall einer nichtbeherrschbaren Schulterinstabilität.

The promising option of arthroscopy-assisted glenohumeral arthrodesis to treat shoulder instability is presented. Compared with open arthrodesis of the shoulder, especially the cosmetic result of this procedure is better. Clinical follow-up revealed that in addition to pain reduction there was an improvement in the shoulder function as assessed according to the Constant and Murley scores. Evaluation of the DASH questionnaire and the Sf-36 health questionnaire clearly showed the improved function of the arm as well as the positive effect on the patients' general state of health.

Prospective randomized comparison of gliding nail and gamma nail in the therapy of trochanteric fractures.

In a prospective randomized study, we compared the new intramedullary implant of the gliding nail to the gamma nail in the fixation of 80 unstable trochanteric fractures in elderly patients. The preconditions of both groups were comparable. We found no differences concerning the operation time, blood loss, period of stationary treatment or social situation. Also, the anatomic reconstruction and the long-term function according to the Merle d'Aubigne score were comparable. Regarding postoperative complications, the gliding nail showed a minor tendency of cutting out; this we attribute to the special design of the dynamic blade and regard it as the most favourable advantage of this new implant.
