Does preoperative hemodynamic preconditioning improve morbidity and mortality after traumatic hip fracture in geriatric patients? A retrospective cohort study.
Dehydration is a major problem in the older population with traumatic hip fractures (THF). A preoperative hemodynamic preconditioning (PHP) protocol may help in achieving hemodynamic stability to ensure adequate perfusion and oxygenation using only clinical parameters to assess cardiovascular performance. ⋯ Level III, therapeutic.

Radial head fractures with interposed capitellar cartilage fragment-hindrance to bone healing-a case series.
Radial head fractures account for the majority of bony elbow injuries. The individual treatment options have been described in detail. In some cases, however, an unusual concomitant injury occurs, which can significantly impede primary osteosynthesis and healing. This concomitant injury can be an interposing cartilaginous capitellar fragment. ⋯ This study presents rare cases of a trapped humeral cartilage fragment in radial head fractures. Radiological imaging including CT scans cannot reliably detect this concomitant injury. Therefore, this problem becomes apparent and treatable only during surgery. A high degree of suspicion is necessary especially in patients with minimally displaced fractures associated with limited elbow motion and a gap at the fracture site as treating these injuries conservatively may lead to poor outcome.

Augmented reality for base plate component placement in reverse total shoulder arthroplasty: a feasibility study.
Accurate glenoid positioning in reverse total shoulder arthroplasty (RSA) is important to achieve satisfying functional outcome and prosthesis longevity. Optimal component placement can be challenging, especially in severe glenoid deformities. The use of patient-specific instruments (PSI) and 3D computer-assisted optical tracking navigation (NAV) are already established methods to improve surgical precision. Augmented reality technology (AR) promises similar results at low cost and ease of use. With AR, the planned component placement can be superimposed to the surgical situs and shown directly in the operating field using a head mounted display. We introduce a new navigation technique using AR via head mounted display for surgical navigation in this feasibility study, aiming to improve and enhance the surgical planning. ⋯ AR may be a promising new technology for highly precise surgical execution of 3D preoperative planning in RSA.

Comparative StudyBiomechanical comparison of screw osteosyntheses and anatomical plating for coronoid shear fractures of the ulna.
Among the few techniques described for the treatment of coronoid fractures, osteosynthesis techniques include screw osteosynthesis from anterior to posterior (AP) or from posterior to anterior (PA) and plate osteosynthesis. The aim of this study was to test the biomechanical stability of screw osteosynthesis and plate osteosynthesis using anatomical plates in coronoid process fractures. ⋯ Basic science study.
