PURPOSE Four-corner fusion is a proven treatment option for degenerative arthritis of the wrist (SLAC/SNAC); however, in some cases, non-union occurs. The purpose of this study was to evaluate the clinical outcome of rearthrodesis in cases of non-union following four-corner fusion. Furthermore, the goal was to identify the cause of non-union and the(More)
BACKGROUND We studied the effects of angiotensin II (Ang II) and diastolic overstretch on the induction of cardiac growth in isometrically contracting muscle preparations from human right atria and left ventricles. We used the gene expression of brain natriuretic peptide (BNP) as a molecular marker of cardiac hypertrophy. METHODS AND RESULTS Northern blot(More)
The artificial dermis Integra (Ethicon, Johnson & Johnson Medical, Norderstedt, Germany) is widely used in the treatment of excessive burn injuries. It is also used in reconstructive surgery when large soft-tissue defects could not be covered with local or free flaps. In this article a 25-year old patient who presented with an early childhood burn of the(More)
INTRODUCTION Venous convulsion after reconstructive microsurgery procedures is one major complication a surgeon has to deal with. Today, especially in the field of reconstructive microsurgery, medicinal leech therapy enjoys a renaissance. The potential risks such as infections associated with leech therapy are generally underestimated and not sufficiently(More)
INTRODUCTION Transplantation of autologous free tissue flaps is the best applicable technique for treating large and complex tissue defects and still has one major failure criterion. Tissue--and in particular muscle tissue--is strongly sensitive to ischemia, thus after a critical period of oxygen depletion the risk of a partial or total flap loss is high.(More)
INTRODUCTION An amputation of the upper extremity and the following replantation is still one of the most challenging operations in the field of reconstructive surgery, especially in extremely severe cases of combined mutilating macroamputations including avulsion and multilevel injuries. Specialists agree that macroamputations with sharp wound edges are an(More)
BACKGROUND The recurrence rate for incisional hernias following reconstruction depends not only on the size of the initial hernia or abdominal wall defect but also on the number of the concomitant diseases. The surgical approach chosen and the level of tension affecting the sutures both represent essential indicators of long-term success in abdominal wall(More)
Free tissue transplantation in burn reconstruction presents a major challenge to reconstructive surgeons. The results of a retrospective analysis of 68 free flaps in 55 patients are reported. This experience facilitated the establishment of reconstructive principles and a decision-making algorithm for primary and secondary reconstruction of burned(More)
Bone tissue engineering approaches increasingly focus on the use of mesenchymal stem cells (MSC). In most animal transplantation models MSC are isolated and expanded before auto cell transplantation which might be critical for clinical application in the future. Hence this study compares the potential of directly auto-transplanted versus in vitro expanded(More)
BACKGROUND AND AIMS This study on healthy test subjects intends to show whether one-off Low-Level Laser Therapy (LLLT) has an instant effect on the perfusion or the oxygenation of the skin tissue. These possible instant effects may have an influence on the accelerated wound healing which is often observed after application of LLLT, in addition to the usual(More)
