[Osteoarthritis of the wrist].

The term osteoarthritis (OA) of the wrist can be used as an umbrella term for various, often independent areas of OA, as the wrist is made up of several joints. Radiocarpal OA often occurs after untreated ligament injuries, incorrectly healed bone fractures in the carpus or after radius fractures involving the joint. A typical sequence of propagation is known for radiocarpal OA following scapholunate (SL) insufficiency or scaphoid pseudarthrosis.

Atypical Palmaris Profundus with Median Nerve Perforation Presenting Ultrasonically as an Intraneural Mass.

An accessory palmaris profundus tendon might cause carpal tunnel like symptoms and in addition is a known potential reason for persistent symptoms following carpal tunnel release. In our case, a 34-year-old female patient presented with paresthesia of the third digit. Electromyography was without pathological findings.

Midterm Results of Four-Corner Fusion Using Dorsal Circular Plate Fixation.

 The purpose of this prospective study was to evaluate the results of four-corner fusion using dorsal circular plate.  We operated on 20 patients between 2009 and 2011.  At a mean follow-up period of 30 months (range: 14-62, SD: 16), the mean VAS improved from 8 (range: 4-10, SD: 2) preoperatively to 4 (range: 0-8, SD: 2).

tracking of adipose tissue grafts with cadmium-telluride quantum dots.

Background: Fat grafting, or lipofilling, represent frequent clinically used entities. The fate of these transplants is still not predictable, whereas only few animal models are available for further research. Quantum dots (QDs) are semiconductor nanocrystals which can be conveniently tracked due to photoluminescence.

Cadmium Telluride Quantum Dots as a Fluorescence Marker for Adipose Tissue Grafts.

Plastic and reconstructive surgeons increasingly apply adipose tissue grafting in a clinical setting, although the anticipation of graft survival is insecure. There are only few tools for tracking transplanted fat grafts in vivo.Murine adipose tissue clusters were incubated with negatively charged, mercaptoproprionic acid-coated cadmium telluride quantum dots (QDs) emitting in the dark red or near infrared.
