[Assessment of REC (Reduction in Earning Capacity) after Thermal Trauma as Part of the Appraisal Process for Statutory Accident Insurance in Germany (Part 2): The New REC Form Developed by Ottomann and Hartmann in 2010].
The calculation of REC forms the basis of expert opinions for the purposes of making accident insurance assessments after an occupational accident or an accident suffered en route while travelling to or from the workplace. The estimation of REC is based on a procedure quoted in the 1995 "Jahrbuch der Versicherungsmedizin" (Yearbook of Insurance Medicine) using a form developed by Henkel von Donnersmarck and Hoerbrand. The overall estimation of damages resulting from the accident comprises 3 main components, namely the functional impairment, the assessment of local findings and the resulting somatic and vegetative complaints. ⋯ The pigmental and textural alterations describing the scar quality are now more precisely defined. Considering the complexity of the somatic and vegetative alterations, more precise (objective) assessments can now be derived. The new REC form increases the validity and transparency of post-thermal trauma REC assessments for the purposes of making statutory accident insurance assessments.

[Analysis of Fit of the Ascension® PyroCarbon PIP Total Joint Component Heads].
The Ascension pyroCarbon proximal interphalangeal (PIP) total joint is available in 4 different sizes, and ideally, the prosthesis head will be flush with the bone. Fit of the Ascension pyrocarbon PIP joint prosthesis has not yet been investigated. ⋯ With occasional exceptions, the proximal and distal component heads of the Ascension pyrocarbon PIP total joint do not accomodate the dimensions of finger phalanges.

[Stabilization of the Distal Radioulnar Joint According to Adams: Clinical, and Radiological Results].
Stabilization of the distal radioulnar joint (DRUJ) with reconstruction of distal radioulnar ligaments as outlined by Adams is indicated if a refixation of the triangular fibrocartilage complex (TFCC) is no longer possible. There is little information given on the results of these procedures in literature. ⋯ The clinical findings show, that reconstruction of distal radioulnar ligaments according to Adams in patients with DRUJ instability and no repairable parts of TFCC, do not allow to re-stabilize the DRUJ in all patients. There is a need for further investigations trying to re-stabilize the DRUJ.

ReviewThe Function of the Distal Interosseous Membrane and its Relevance to the Stability of the Distal Radioulnar Joint: An Anatomical and Biomechanical Review.
The purpose of this article is to review functional anatomy and biomechanics of the distal interosseous membrane (DIOM) and its relevance to the stability of the distal radioulnar joint. The intact DIOM constrained dorsal dislocation of the radius, but it seldom constrained palmar dislocation. ⋯ Ulnar shortening with the osteotomy performed proximal to the attachment of the DIOM had a more favorable effect on stability of the DRUJ compared with the effect of distal osteotomy, especially in the presence of the distal oblique bundle (DOB). The longitudinal resistance to ulnar shortening was significantly greater in proximal shortening than in distal shortening.

[Analysis of the Design of the Ascension® PyroCarbon PIP Total Joint Proximal Component in Relation to the Proximal Phalanx Morphology].
There are many indications that long-term stability of the Ascension(®) pyrocarbon proximal interphalangeal (PIP) total joint is not attained by osseointegration but by appositional bone formation. Accordingly, good locking by cortical bone for sufficient primary stability is necessary in order to avoid prosthesis loosening before enough new bone has been formed. The size of the proximal component of the Ascension(®) PyroCarbon PIP total joint and thus cortical anchorage and primary stability depend on the morphology of the proximal finger phalanx and, especially, on the isthmus of the distal medullary canal. ⋯ Ideal cortical contact between the isthmus of the proximal phalanx and the largest proximal component of the Ascension(®) pyrocarbon PIP total joint prosthesis that can be inserted, and thus good primary stability, is not possible due to a mismatch in the frontal plane between the morphology of the proximal phalanx and the prosthesis. But good contact can be achieved in the sagittal plane by broaching the medullary canal.
