[Microsurgical Autologous Lymph Vessel Transplantation: Does Harvesting Lymphatic Vessel Grafts Induce Lymphatic Transport Disturbances in the Donor Limb?].
The aim of this study was to determine whether the extirpation of lymphatic vessels induces lymphatic transport disturbances in the donor limb of patients following the harvest of lymph vessel grafts. ⋯ The results show that microsurgical transfer of lymph vessel grafts is possible without compromising lymphatic drainage of the donor limb if safety precautions are taken into account.

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 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.

[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.

[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.
