Vollschichtige Hautdefekte uber funktionellen Strukturen (Sehnen, Gefase) oder denudiertem Knochen an den Extremitaten machen in der Regel aufwandige Weichteilplastiken zur Defektdeckung notwendig. Als neue Option bei der Defektdeckung steht die bovine Kollagen-Elastin-Matrix MATRIDERM® zur Verwendung als Neodermis unter Hauttransplantaten zur Verfugung. Kann die einzeitige Transplantation mit MATRIDERM® und ausgedunnter Vollhaut oder Spalthaut uber denudierten Knochen oder freiliegenden Sehnen eine suffiziente Defektdeckung erreichen? Bei insgesamt 10 Patienten wurde anstatt plastisch-chirurgischer Defektdeckungen, MATRIDERM® in Kombination mit Spalthaut/Vollhaut in einem einzeitigen Deckungsverfahren angewandt. Es wurde die Einheilungsrate der einzeitig und kombiniert verwandten Transplantate auf einem generell mit grosen Hauttransplantatverlusten verbundenem Wundgrund (denudierter Knochen und Sehnen ohne Paratenon) ermittelt. Bei 9 von 10 Patienten konnte mit dem kombinierten Verfahren durch MATRIDERM® und Hauttransplantation eine vollstandige Defektdeckung erzielt werden. Dabei war ein einzeitiger Wundverschluss uber freiliegenden Sehnen ohne Paratenon in 4 von 5 Lokalisationen unter Erhalt der Funktion zu erreichen gewesen. Uber deperiostierten knochernen Defekten war ein einzeitiger komplikationsfreier Verschluss jedoch nur in 2 von 6 Lokalisationen erfolgreich gewesen. Insgesamt konnte jedoch mit einer zweiten Spalthauttransplantation bei vaskularisiertem MATRIDERM® ein vollstandiger Wundverschluss an der Wunde mit freiliegender Sehne und in 3 der 4 knochernen Lokalisationen erzielt werden. Bei einem Patienten mit freiliegendem Olecranon konnte eine lokale Transpositionslappenplastik zum abschliesenden Verschluss angewendet werden. Durch die ein- bzw. zweizeitige Verwendung von MATRIDERM® uber frei liegenden Sehnen sowie Knochen kann ein effektiver Defektverschluss ohne die Notwendigkeit eines komplizierteren plastisch-rekonstruktiven Verfahrens erzielt werden. Einen Ersatz fur Lappenplastiken in Bezug auf ihre Funktionalitat kann dieses Verfahren nicht darstellen. Durch die Verwendung von MATRIDERM® besteht aber in ausgewahlten Fallen eine erweiterte Indikationsmoglichkeit fur Spalthauttransplantationen bei plastisch-rekonstruktiven Eingriffen. more...

Summary Introduction Extravasations of chemotherapeutic drugs may lead to tissue necrosis and subsequent tissue defects, sometimes resulting in loss of function. In the absence of therapy, approximately one-third of vesicant extravasations will result in ulcerations, some of which necessitate plastic microsurgery to cover the soft tissue defects. The aim of this study was to describe the surgical technique itself and to present clinical results of the procedure in a clinical series of chemotherapeutic extravasation injuries that benefitted from a subcutaneous wash-out procedure (SWOP) by minimisation of serious complications. Patients and methods Over a time period of 3 years, we treated 13 female patients following chemotherapeutic extravasation injury. Nine of the cases involved a high vesicant chemotherapy agent, and four patients involved chemotherapy with low vesicant potential. The therapeutic approach was performed using SWOP exclusively without the application of specific antidotes. Results The mean time interval between the extravasation injury and the SWOP was 345min (140–795min). In none of the cases was there a tissue breakdown, but there was a steady decrease in the inflammatory reaction of the cutaneous and subcutaneous soft tissues without additional complications over a 3-month follow-up period. Conclusion The results of the study suggest that SWOP is a minimally invasive, safe and effective emergency treatment for chemotherapeutic extravasation injury. Based on the absence of comparative studies with regard to the efficacy of conservative therapy, SWOP should be offered as a therapeutic option for chemotherapeutic extravasations, especially in cases of medical malpractice and also as a defence in case of a legal conflict. more...

Surgery - Abstract
Die karpale Instabilitat kann als gestorte anatomische Ausrichtung der im Karpus artikulierenden Knochen untereinander verstanden werden. Diese gestorte Balance unter physiologischer Krafteinwirkung tritt entweder nur dynamisch (unter Bewegung) oder bereits statisch in Ruhe auf. Die haufigsten Ursachen fur karpale Instabilitaten sind das Handgelenkstrauma mit Ruptur der stabilisierenden Bander und die adaptive Fehlstellung nach Frakturen des Radius oder Karpus. Dabei nimmt der karpale Kollaps durch eine nicht verheilte Fraktur des Skaphoids eine besondere Rolle ein. Daneben konnen degenerativ entzundliche Veranderungen wie die Chondrokalzinose oder die Gicht, seltener aseptische Knochennekrosen des Lunatums oder Skaphoids oder anlagebedingte Fehlstellungen (Madelung-Deformitat) zu einer Handwurzelinstabilitat fuhren. Die fehlgestellten Gelenkflachen fuhren unter erhohtem Druck zur Knochenarrosion mit sekundarer Arthrose des Handgelenkes. Um diesen unwiderruflichen Prozess aufzuhalten oder zu verlangsamen, ist die moglichst fruhe Diagnostik notwendig. Zahlreiche Operationsmethoden sind erdacht worden, um eine erneute Stabilitat herzustellen. Die Operationsmethoden reichen von der direkten Rekonstruktion verletzter Bander uber Bandersatzoperationen, bis hin zu Teilversteifungen der Handwurzelgelenke. more...

Diese Arbeit soll den aktuellen Stand der Kooperation zwischen Plastischen Chirurgen und Gynakologen in zertifizierten Brustzentren darstellen. Die Rate der Brustrekonstruktionen nach nichtbrusterhaltender Therapie ist mit 8–13% sehr niedrig. Der Plastische Chirurg ist auch bei zertifizierten Brustzentren haufig nicht Teil des Teams. Uber das Westdeutsche Brustzentrum (WBC) wurden 220 im Jahr 2007 an das WBC angeschlossene Kliniken angeschrieben. 80 Kliniken schickten einen Fragebogen zuruck. Die Untersuchung basiert auf den Daten von ca. 24.000 Patientinnen. Von den 80 Kliniken waren zum Zeitpunkt der Untersuchung 60 Kliniken (75%) als Brustzentrum zertifiziert. Die Zertifizierung erfolgte nach unterschiedlichen Vorgaben: Land Nordrhein-Westfalen, DKG/DGS (Deutsche Krebsgesellschaft/Deutsche Gesellschaft fur Senologie), EUSOMA, andere. In 8 Kliniken (10%) wurde ein Plastischer Chirurg als operativ tatiger Facharzt und Teil des Brustzentrums benannt. Die meisten Brustzentren (44 von 80 Kliniken) arbeiten mit 3 bis 4 operativ tatigen Facharzten. Die Zusammenarbeit innerhalb eines Brustzentrums zwischen Gynakologen und Plastischen Chirurgen kann ausgebaut werden. Nicht jede Frau braucht nach einer Mastektomie einen (mikrochirurgischen) Brustaufbau, aber jede betroffene Frau hat das Recht auf eine Aufklarung uber alle zur Verfugung stehenden Rekonstruktionsverfahren inklusive der mikrochirurgischen Verfahren. more...

Pleiotrope Substanzen sind durch ihr ausgesprochen vielfaltiges und komplexes Wirkspektrum charakterisiert und dies macht sie fur die Therapie von Wunden attraktiv. Neben seinem bekannten Effekt der Steigerung der Hamatopoese konnte das Glykoproteinhormon Erythropoietin (EPO) in diversen anderen Organen eine deutliche Gewebeprotektion aufzeigen. Der Einsatz von EPO im Rahmen von Regenerationsprozessen der Haut basiert hier wahrscheinlich im Wesentlichen auf seiner zytoprotektiven, proangiogenen, antiapoptotischen sowie antiinflammatorischen Wirksamkeit. Hier kann EPO durch eine niedrigdosierte bzw. einmalige Applikation die strukturelle und koordinierte Interaktion verschiendener Zelltypen untereinander stimulieren. Diese Ubersichtsarbeit soll die Vor- und Nachteile einer EPO-Gabe im Rahmen verschiedener Heilungs- und Regenerationsvorgange der Haut aus der experimentellen Forschung beleuchten und mogliche klinische Anwendungen diskutieren. more...

Today split or full skin grafts are still the gold standard in the treatment of substance defects of the skin. Such results can be seen, for example, in the therapy for burn patients. However, in patients with more than 50% burned skin area, donor sites are limited. Likewise in chronic wound patients inferior take rates of skin grafts as compared to burn wounds are observed. This may be attributed, for example, to accompanying or underlying chronic diseases or a higher rate of local infections. These phenomena also lead to a lack of availability of transplantable skin grafts. Hence the need for cost effective and user friendly synthetic or engineered skin grafts, which can serve for acute and chronic wounds and which can be also used in critically ill patients, is at hand. During the last 30 years a huge number of biological and synthetic skin graft materials and products based on the patient's own cells were launched on the market. Researchers and clinicians are constantly working on further improvements. One possibility is the engineering of skin grafts in vitro, which have to be integrated into the wound bed after transplantation. Another approach is the fabrication of biocompatible and bioresorbable matrices, which can attract host cells and stimulate a wound-healing process without scars. However, the skin graft materials available today cannot yet replace split or full skin grafts completely because of their inherent limitations such as insufficient take rates and/or the lack of mechanical stability and differentiated structures of the grafted artificial skin. Thus researchers in the field of skin tissue engineering are still working on the final goal of developing a skin graft which has all the features of healthy human skin and is capable of replacing human skin completely. This article gives on overview of the currently available solutions and products in the field of skin tissue engineering. more...

One hundred years after the first description of autologous fat transplantation, this technique is receiving renewed attention. Initially, critically reviewed by plastic surgery societies, particularly those in the United States, the transfer of autologous fat was recently addressed at the September 2009 annual meeting of the German Society of Plastic Reconstructive and Aesthetic Surgeons in Hannover. In this consensus meeting, the panel reviewed both the current status of autologous fat transfer as well as established data concerning this evolving practice. In Germany, autologous fat transplantation is regulated by the Law on Tissue Transfer and Processing (Gewebegesetz). In an effort to facilitate future comparisons it is mandatory to describe harvesting, processing and reinjection techniques in detail. The consensus panel concluded that fat should be harvested using low vacuum settings and then transplanted in thin layers (Evidence V). Quantification of transplanted fat can best be performed by MRI (Evidence level III). Limited clinical studies are available with only some reaching a level of evidence II. At present, risk associated with autologous fat transplantation is considered to be minor. Tumor induction by autologous fat grafting is not proven. New techniques like stem cell enriched fat grafts may offer new promise for the Plastic and Reconstructive Surgeon. more...

Plastisch-rekonstruktive Eingriffe werden primar unter kurativer Indikationsstellung im Rahmen der onkologischen Behandlung von malignen Tumoren des Kopf-Hals-Bereichs, des Ruckens und der Extremitaten durchgefuhrt. Wenig bekannt sind plastisch-rekonstruktive Eingriffsmoglichkeiten bei Patienten, die an lokal fortgeschrittenen oder inkurablen Tumoren leiden. Zu diesen palliativen Indikationen zahlen oberflachliche, grostenteils exulzerierende und superinfizierte Geschwulste, die fur die Patienten aufgrund zahlreicher Begleiterscheinungen eine drastische Einschrankung ihrer Lebensqualitat bedeuten. Schmerzen, Sickerblutungen, bakterielle Superinfektionen mit Geruchsentwicklung fuhren zu Beeintrachtigungen von Allgemeinbefinden, Selbstwertgefuhl und Aktivitat. Nicht wenige Patienten unterliegen einer zunehmenden Isolation. Gerade diese Patientengruppe kann von stadiengerecht indizierten plastisch-chirurgischen Eingriffen erheblich profitieren. In diesem Beitrag werden daher die Moglichkeiten palliativer Resektionen und plastischer Rekonstruktionen und deren krankheitserleichternder Nutzen fur Patienten mit inkurablen Tumoren dargestellt. more...

BACKGROUND While use of biocomposite temporary dressings in burn wounds is common practice, the complex anatomic structures of the hand make this treatment option challenging. For this reason, the Biobrane ((R)) Glove (SmithN max. 3.33) and VSS median of 3 (min. 0; max. 5)]. Wound healing times were lower (mean 9 days). According to patients' response to overall acceptance, 90% responded as being "very satisfied" with Biobrane ((R)) Glove treatment and 75% responded that Biobrane ((R)) Glove treatment was "much less painful" compared to conventional burn management. The material costs of the Biobrane ((R)) Glove treatment, over 14 days, were approx. double compared to conventional wound management costs. In contrast, the time required for conventional wound management over 14 days was four times longer than for treatment with Biobrane ((R)) Gloves. Thus, taking personnel expenses into consideration, total costs of Biobrane ((R)) Glove treatment are comparable to those of conventional wound management. CONCLUSION Biobrane ((R)) Glove treatment of hand burns resulted in excellent functional and cosmetic outcomes, reduced pain compared to conventional wound management and high overall patient satisfaction. In conjunction with a significant reduction in wound management time, the Biobrane ((R)) Glove is an important and cost neutral tool in the treatment of second degree burn wounds of the hand. more...

Purpose/background Keratinocyte transplantation after burn injury and in chronic wound treatment is a potentially useful method in clinical practice. As transfer of keratinocytes is easily monitored and gene expression is controllable by topical administration of inductors, keratinocyte cultures are an especially interesting medium for gene therapeutic approaches far above of wound healing applications. A major obstacle is the standardization of keratinocyte preparation and maintenance of pure proliferative cultures for clinical application. The best outcomes in previous protocols were obtained using fibroblasts as a feeder layer, a requirement for long-term expanded cultures. Cell expansion and a high purity of keratinocytes are prerequisites for clinical transfer studies. Here, we describe a human keratinocytes preparation method that allows cell proliferation and expansion in culture without a feeder layer. Materials and methods Human keratinocytes were prepared from skin biopsies and cultured on untreated plastic culture dishes using Waymouth medium the first days followed by a change to a commercially available serum-free keratinocyte medium. The cells were characterized morphologically followed by transfection. For positive selection, transfected cells were selected by the cotransfection system pMACS Kk and magnetic cell sorting. Results Transfection rates were determined by expression of GFP vector which were 35%. The usage of magnetic cell sorting resulted in positive selection of transfected cells. Positive cells were able to adhere and proliferate after the sorting procedure. High viability and expansion of plastic adherent keratinocytes was achieved allowing up to 5 passages without signs of senescence and the doubling times were 3-5 days. The cells displayed typical keratinocyte morphology and immunostaining confirmed high keratinocyte purity. The number of contaminating fibroblasts was low. Conclusion Here, we describe an efficient and inexpensive method for a standardized human keratinocyte isolation without the need of a fibroblast feeder layer. This protocol may facilitate the clinical application of cell based therapies in burn injuries or chronic wounds using keratinocytes. more...

INTRODUCTION The frequency of perforator flap surgery is increasing. As such, the claim to identify and localize the perforators is closely related to preoperative perforator imaging. Starting with Doppler sonography magnetic resonance imaging (MRI) followed early in the 90s. Recently, three- and four-dimensional computer tomographic angiography and venography present impressive preoperative illustrations of perforators. HYPOTHESIS Duplex ultrasound dominates in clinical practice for perforator imaging. METHODS We performed a survey using a multiple choice questionnaire which was distributed among consultants of the German plastic surgery society (DGPRAC). Response rate was 46% with 132 institutions responding. RESULTS Preoperative perforator imaging is applied in 77%. Duplex sonography is predominant with 70%, followed by colour Doppler ultrasound (42%). CT angiography (7%) and MRI angiography (8%) are currently underutilized. The amount of perforator flaps performed did not favor any preoperative perforator diagnostic. However, among those performing more than 30 perforator flaps per year, only 2% did not perform any perforator diagnostic at all. CONCLUSION Preoperative perforator imaging is applied in 3/4 of all perforator flaps with duplex ultrasound dominating. Angio-CT and Angio-MRI are currently infrequently used for preoperative perforator imaging in Germany to date. more...

Gynecology ,medicine.medical_specialty ,Transplant surgery ,business.industry ,Medicine ,Surgery ,business - Abstract
Die plastische Chirurgie mit ihren vier Saulen, der rekonstruktiven, Hand-, Verbrennungs- und asthetischen Chirurgie, behandelt neben Patienten mit primaren Erkrankungen, wie erworbenen Defekten oder angeborenen Fehlbildungen, vor allem Patienten mit operativen und nichtoperativen (multimodalen) Therapiefolgen. Da in vielen Fallen plastisch-rekonstruktive Korrektureingriffe bzw. funktionelle und asthetische Rekonstruktionen die einzigen noch zur Verfugung stehenden Behandlungsalternativen darstellen, kommt einem komplikationslosen Behandlungsverlauf hochste Bedeutung zu. Das Patientengut der plastischen Chirurgie rekrutiert sich aus allen Altersgruppen beider Geschlechter, von Kleinkindern bis zu Patienten fortgeschrittenen Lebensalters. Dabei erstrecken sich die Indikationen in allen Altersgruppen von Traumafolgen uber onkologische Folgezustande bis hin zu angeborenen Fehlbildungen bzw. Formstorungen. Eine spezielle Herausforderung stellt die plastische Chirurgie des alten, multimorbiden und pathologisch adiposen Patienten dar. Zwar ist ein hohes Lebensalter uber 70 Jahren per se noch nicht mit einer erhohten eingriffsspezifischen Komplikationsrate verbunden, jedoch mit haufiger auftretenden medizinischen Problemen, wie es von dieser Altersgruppe generell zu erwarten ist. Risikofaktoren wie Alkoholismus und koronare Herzerkrankung erscheinen dabei eher als unabhangige Pradiktoren perioperativer Komplikationen. Somit konnen auch altere und morbide Patienten bei entsprechendem Risiko- und Komplikationsmanagement von plastischen und wiederherstellenden Operationen profitieren. Ein zeitgemases Komplikationsmanagement bei plastisch-chirurgischen Eingriffen beginnt bereits fruhzeitig mit sorgfaltiger Patientenselektion, Risikoeinschatzung und patientenadaptierter Auswahl geeigneter Behandlungsverfahren. Es erfordert daher neben dem primar sicheren Beherrschen des plastisch-operativen Spektrums vor allem Kenntnisse in konservativen und operativen Alternativmethoden, respektive Reserveverfahren, um chirurgisch-technische Zwischenfalle sowie Durchblutungs- und Wundheilungsstorungen sicher beherrschen zu konnen. Dieser Beitrag stellt diese spezifischen Aspekte des postoperativen Komplikationsmanagements in der plastischen Chirurgie dar. more...

Plastic surgery has a long tradition in transplantation issues. Skin transplantation has been introduced by plastic surgeons Padgett and Brown. The first kidney transplantation was performed by Dr. Murray, a plastic surgeon. Composite tissue allotransplantation (CTA) is an evolving new field with transplantation of hand, vascularised knees or partial faces. With the European Union (EU) directive 2004/23/EC come into effect with the German tissue law at August 1, 2007 one has question the classification of transplantation of the hands, arms or the face as tissue or organ transplantation. While solid organs are allocated based on the German Deutsche Stiftung Organspende (DSO) and EuroTransplant, this is not the case for tissues. While for example thoracic organ procurement is performed in heart-beating organ donors with established hemodynamics, this is not the case for tissues, either. Given the complexity of a hand or a face as a sample of bones, muscles, nerves, vessels, and skin this has to be taken into account for example in comparison to a cornea as a tissue graft. As such, Dr. Siemionow has proposed a face to be regarded as an organ when comparing it to a kidney. Currently, allocation procedures as well as procurement issues in CTA are much more similar to organ- rather than tissue transplantation. Thus, we believe that CTA of hands or partial faces has more similarities to organ than to mere tissue transplantation. more...

The stage-adjusted therapy of thermal injuries is based on pathophysiologic mechanisms as well as functional and aesthetic requirements. Plastic reconstructive surgical approaches are highly important in the prevention of the frequent grave sequelae of thermal trauma and to achieve optimal functional rehabilitation and favourable outcome. In reconstructive surgery of burns operative goals are subdivided into acute, secondary reconstructive, functional and aesthetic indications. The achievement of early wound closure to preserve functional skin and soft tissue components is an essential part of acute reconstructive procedures. Functional reconstructive and aesthetic procedures supplement the conservative treatment modalities of the secondary phase of burn care with physical therapy, ergotherapy and psychological support. more...

Despite significant advances in burn surgery and critical care, severe burn trauma defined as injuries covering more than 25% of the total body surface area, is still associated with high mortality and morbidity. Burn trauma is a whole body injury where peripheral dermal injury rapidly results in systemic inflammation and inflammatory core organ damage. The severe disturbance of internal homeostasis involves all vital organ systems and obligates early referral to specialized burn centers. Treatment of severely burned patients is a multifaceted challenge directed by pathophysiologic events which progress from local skin destruction, disruption of physicochemical and microvascular barriers to breakdown of peripheral and central circulation, organ failure and ultimately death. While early intensive care focuses on maintenance of tissue oxygenation and perfusion, surgical treatment deals with management of the burn wounds as a source of inflammation and infection. Here wound debridement and coverage is essential to abrogate systemic effects of inflammation and limit pathogen invasion. While control of early burn stages minimizes mortality due to burn shock, subsequent burn sepsis continues to be a formidable challenge for physicians and the main cause of burn mortality. more...

If pharmaceutic modulation of scar formation does not improve the quality of the healing process over conventional healing, the surgeon must rely on personal skill and experience. Therefore a profound knowledge of wound healing based on experimental and clinical studies supplemented by postsurgical means of scar management and basic techniques of planning incisions, careful tissue handling, and thorough knowledge of suturing remain the most important ways to avoid abnormal scarring. This review summarizes the current experimental and clinical bases of surgical scar management. more...

Transplantations play an increasing role for plastic reconstructive surgeons. The increasing number of solid organ transplantations and the improved long-term survival rates lead to increased numbers of these patients also undergoing plastic and reconstructive procedures. Free flap transfer in solid organ transplant patients is feasible with no higher risk to both transplant function and postoperative complications than for nontransplant patients, even during immune suppression. Composite tissue allotransplantation (CTA) is an evolving field in plastic reconstructive surgery with hands, arms, partial faces, abdominal walls, and knee joints being transferred in clinical settings. However only an interdisciplinary approach using all available resources in highly selected patients after exhausting all other plastic reconstructive procedures is able to achieve reasonable results. The potential complications of long-term immune suppression and patient compliance have to be balanced with the expected and achieved functional result of CTA, whose procedures must be discussed as a potential tissue or organ transplantation, given the legal and logistic implications. The interdisciplinary cooperation of transplant surgeons, microsurgeons, psychologists, and ergo- and physiotherapists is mandatory to achieve successful CTA results. more...

BACKGROUND AND AIMS: Burn injuries are a serious threat to individuals with altered consciousness during epilepsy. The objective of this study detailing 33 individuals who sustained scalds or burn injuries during an epileptic seizure, was to clarify typical injury mechanisms, extent, therapy and sequelae of these injuries and thus identify potential preventive measures to protect this special population from thermal trauma. RESULTS: Overall, 16 women and 17 men with a mean age of 39.6 (range: 21 - 76) years were included in this retrospective review. The burned body area averaged 16 % (maximum: 51 %), 30 of the 33 patients (91 %) required burn wound excision and skin grafting. The mean ABSI score was 5.5 (range: 3 to 11) points. Thermal trauma mostly occurred as hot water scalds (n = 19) during showering or bathing in a tub (n = 15), followed by falls during cooking or into open fire. None of our patients was informed about the risk of experiencing severe thermal injuries during epileptic seizures. The length of intensive care averaged 33 days (maximum: 79 days), all patients survived. The estimated treatment costs were at least 50,000 Euros per patient. DISCUSSION: In conclusion, epileptic seizures can cause severe and deep thermal trauma. Our data shows that most of these injuries happen at home and may be easily prevented by simple safety devices, such as water thermo-regulators or the avoidance of high-risk situations, it seems advisable to inform patients with epilepsy and their families and care-givers of this specific danger. more...

Die Ausbildung zum Facharzt in einem chirurgischen Fachgebiet leidet zunehmend an einem Mangel an Praxis und einer Zunahme an burokratischen Aufgaben. Zudem kommen gesetzliche Vorgaben in Form des Arbeitszeitgesetzes hinzu. Diese Faktoren fuhren dazu, dass grundlegende praktisch chirurgische Techniken nicht mehr flachendeckend auf einem qualitativ hohen Niveau im Rahmen der Facharztausbildung angeboten werden konnen. Wir mochten mit dem von uns entwickelten Lappensimulator „Flap Lab I der MHH“ einen praktischen Beitrag zur Verbesserung der chirurgischen Ausbildung leisten, da wir mithilfe dieses Lappensimulators realitatsgetreue Bedingungen schaffen konnen, um die Prinzipien der Planung und Anwendung von lokalen Lappenplastiken zur Defektdeckung nachzuvollziehen und eigentatig auszufuhren. Der Lappensimulator „Flap Lab I der MHH“ hat sich bereits in mehreren Weiterbildungskursen als sehr gutes Trainingsmodell bewahrt. Im Rahmen dieser Arbeit werden u. a. Z-Plastiken, gegenlaufige Z-Plastiken („Hanging-man-Plastik“) und der Limberg-Lappen vorgestellt. more...

Matriderm is a dermal substitute consisting of a native (non-cross-linked) collagen matrix supplemented by a elastin hydrolysate. It is available in sheets of 1 mm and 2 mm thickness, and may be covered in a single step procedure with immediate split thickness skin grafting. Duration of the surgical procedures are only marginally increased. There is no diminished take of split thickness graft and only marginally prolonged healing time compared with the split thickness graft only. In experimental models the matrix reduces wound contracture, histologically collagen bundles in the scar are more randomly orientated. Clinical trials with a long-term clinical evaluation showed no difference in scar elasticity between the described dermal substitute and split thickness grafts alone. There is a lack of clinical data on the development of wound contracture. more...

Numerous excision and liposuction techniques have been described to correct bilateral male breast enlargement. Yet little attention has been directed towards the rare cases of unilateral gynecomastia which have frequently been suspected to be malignant. The purpose of this study was to investigate the results of surgical gynecomastia management and the roles of different treatment modalities in a large patient cohort with special attention to etiology, treatment and outcome in the cases of unilateral involvement. more...

INTRODUCTION: After its first description 1990 by Maruyama, the DMCA flap has been used for several indications. In 1999 Pelissier published his “extended DMCA flap” with a wider arc of rotation. Compared to the most frequent indications for the DMCA flap, palmar digital soft tissue defects after infection are rare. CASE REPORT: A 35-year-old male stockman presented with a severe phlegmonous infection of the middle finger. Repeated debridements led to a soft tissue defect on the palmar side of the middle finger. After vain initial attempts the patient quit smoking and the DMCA II and III could be detected by ultrasonic Doppler probe. An extended DMCA II flap was performed to cover the soft tissue defect. Due to acute intraoperative ischaemia of the flap after elevation and rotation, the flap was repositioned to the donor site. After preconditioning for ten days, the transposition of the flap could be performed without any further problems. There were no postoperative complications. The length and the form of the finger could be preserved. CONCLUSION: Even in the case of palmar soft-tissue defects due to infections, the expanded DMCA flap may be a valuable option for coverage. It may be possible to localise the dorsal metacarpal arteries by ultrasonic Doppler probe in a smoking patient after a period time of nicotine abstinence, if initial attempts at detection fail. If the perfusion of the rotated extended DMCA flap appears to be compromised, we recommend the repositioning of the flap. Its transposition may be safely performed after a preconditioning period. more...

Die Lahmung der Beuge- oder Streckfunktion des Ellenbogens beeintrachtigt die Funktion der gesamten oberen Extremitat in hohem Mase. Zur chirurgischen Rekonstruktion stehen verschiedene Verfahren zur Verfugung. Liegt eine periphere Nervenschadigung erst kurze Zeit zuruck, sollte eine anatomische Rekonstruktion mittels Nervennaht oder Nerventransplantation versucht werden. Alternativ ist eine Nerventransposition moglich. Nach mehr als 12–18 Monaten ist eine Reinnervation der gelahmten Muskeln nicht mehr zu erwarten. Dann konnen motorische Ersatzoperationen mit Muskeltranspositionen hilfreich sein. Eine Rekonstruktion der Flexion ist vorwiegend nach Plexusschaden erforderlich, bei denen die Mm. biceps brachii, brachioradialis sowie brachialis verloren gehen. Als Ersatzmotoren stehen die Mm. latissimus dorsi, pectoralis major und triceps brachii zur Verfugung. Daneben ist eine Proximalisierung der Unterarmbeuger- und -pronatorenmuskeln (Steindler-Operation) moglich. Die Indikation zur Verlagerung der M. latissimus dorsi zur Ellenbogenbeugung besteht vor allem bei Defekten des vorderen Muskelkompartiments. Bei proximaler N.-radialis-Lasion eignet sich die Latissimustransposition auch zur Wiederherstellung der Ellenbogenstreckung. Bei Patienten mit Tetraplegie wird die Ellenbogenstreckung meist mittels des um ein Sehnentransplantat verlangerten hinteren Anteils des M. deltoideus oder durch eine Bizeps-pro-Trizeps-Umlagerung rekonstruiert. more...

- Abstract
Eine Wunde ist die Unterbrechung des Gewebszusammenhangs an auseren oder inneren Korperoberflachen mit oder ohne Gewebeverlust. Zumeist ist sie durch ausere Gewalt verursacht, kann aber auch alleinige Folge einer Krankheit sein, wie etwa beim Geschwur (Ulkus). Die haufigste Ursache fur eine Entzundung ist eine banale Verletzung, durch die Krankheitserreger in die Weichteile eindringen. Die Behandlungsmoglichkeiten von Wunden und Entzundungen der Weichteile, auch von speziellen Formen wie dem diabetischen Fus, dem Ulcus cruris venosum, bei Vorliegen eines Dekubitus sowie die Narbenbehandlung, werden in diesem Kapitel beschrieben. more...

Nervenverletzungen der oberen Extremitat fuhren oft zu schweren Funktionsbeeintrachtigungen. Ein wichtiges Kriterium fur die Indikation zur Ersatzoperation ist das soziale und berufliche Profil des Patienten. Motorische Ersatzoperationen konnen in jeder Phase nach der Verletzung zu einer Wiederherstellung verlorener Nervenfunktionen und zur Besserung der Handfunktion fuhren. Sie bieten dem Patienten eine therapeutische Alternative zur dauerhaften Lahmung bzw. zur langfristigen Schienenbehandlung an und verkurzen die Rehabilitationsperiode. An der oberen Extremitat sind fur alle Stammnerven zahlreiche Ersatzoperationen bekannt, deren Prognose vom Lahmungsmuster, den lokalen Unfallschaden sowie den Eigenschaften des Spendermuskels abhangt. Auch bei komplexen Schadigungen mit geringerer Funktionswiederkehr als nach isolierten motorischen Ausfallen ermoglichen Ersatzoperationen einen wertvollen Funktionsgewinn. Obwohl leider viel zu selten angewandt, bieten motorische Ersatzoperationen auch bei mehr als 70% der Patienten mit Querschnittslahmung im Halsmarkbereich (Tetraplegie) die Moglichkeit zu einer gebesserten Handfunktion. Der Beitrag gibt einen Uberblick uber die in der Praxis bewahrten Techniken der motorischen Ersatzoperationen an der Hand nach peripheren Nervenverletzungen und bei Tetraplegie und soll damit die Indikationsstellung zu diesen Operationen weiter stimulieren. more...

The fingertip is an extremely specialized end organ with a highly developed sense of touch. In this article, we present the different ways of reconstructing a traumatized fingertip. Additionally, we systematically explain the differential indications for the different techniques available. The whole spectrum of fingertip reconstruction is discussed, starting from local neurovascular flaps (palmar VY-Atasoy flap, Kutler flap, palmar Moberg flap, lateral Venkataswami and Subramanian flap, palmar Hueston flap), distant flaps (Littler flap, Foucher flap, dorsal metacarpal artery flap, cross-finger flap, reversed cross-finger flap) and finally free flap transfer (free toe-pulp transfer, spare-part transplantation). The advantages and disadvantages of each flap are highlighted. We develop an algorithm to facilitate finding the correct type of reconstruction. more...

Medical leech therapy has enjoyed a renaissance in the world of reconstructive microsurgery during recent years. Especially venous congestion is decreased using hirudo medicinalis application such as following replantation of amputated fingers or congested flaps. They provide a temporary relief to venous engorgement whilst venous drainage is re-established. Living in symbiosis with Aeromonas hydrophila, who can digest the sixfold blood meal related to their body weight, and a broad number of anticoagulant agents such as the thrombin inhibitor hirudin, apyrase as well as collagenase, hyaluronidase, Factor Xa inhibitor and fibrinase I and II, leeches decrease venous congestion. Laser Doppler flowmetry could demonstrate a significant increase in superficial skin perfusion following leech application 16 mm around the biting zone. Following the initial blood meal accounting for about 2.5 ml, the anticoagulant effect of the various leeches enzymes follows within the next 5-6 hours, which both account for the beneficial effects. Infection associated with leech therapy is a documented complication of leech application, with reported incidences ranging from 2.4 to 20 % and a chinolone antibiotic is currently recommended to face the potential Aeromonas hydrophila infection. Anemia is a second adverse effect during medicinal leech application which has to be taken account with repetitive blood samples. Besides the successful applications of leeches in various applications in plastic and reconstructive microsurgery, randomized-controlled trials are pending to elucidate the value of hirudo medicinalis according to evidence-based criteria above from case series and case studies. more...

Die drainierenden Lymphknotenstationen extraabdomineller maligner Tumoren der unteren Korperhalfte finden sich inguinal und entlang der externen Iliakalgefase. Eine Notwendigkeit zur operativen Intervention ergibt sich bei der onkologisch-chirurgischen Therapie von Tumoren mit dominantem lymphatischem Abfluss aus dem Anorektum, Genitale, Hauttumoren, Weichteilmalignomen der unteren Abdominalregion und unteren Extremitat oder bei primaren Lymphknotenerkrankungen. Die aktuellen Erkenntnisse uber die Biologie der Malignome, deren Metastasierungwege und die Moglichkeiten der Markierung mittels des Sentinel-Verfahrens, vor allem beim malignen Melanom, haben die Strategie der Lymphknotenchirurgie in den letzten Jahren masgeblich beeinflusst und die radikale Lymphadenektomie zugunsten einer differenzierten Lymphadenektomie abhangig vom Tumortyp in den Hintergrund treten lassen. Eine Indikation zur Lymphadenektomie ergibt sich heute daher entweder in Form einer alleinigen diagnostischen Lymphknotenentfernung ohne klinischen Befund (Sentinel), mit klinischem Befund oder als regelhafte therapeutische Lymphadenektomie. Als weitere Indikation gilt die Lymphadenektomie im Rahmen palliativer Eingriffe. Der Schonung der Lymphabflusswege und Reduktion von Wundheilungsstorungen wird zunehmend Bedeutung zugemessen. In diesem Beitrag sollen der aktuelle Stand der Differentialindikation, technischen Durchfuhrung und die dabei zu berucksichtigenden prognostischen Uberlegungen fur die Lymphadenektomie der Inguinal- und Beckenregion dargestellt werden. more...

Der Komplettverlust der Achillessehne gilt als stark beeintrachtigende Verletzungsfolge, daher wird eine Rekonstruktion angestrebt. Diese Studie stellt erstmals eine standardisierte Nachuntersuchung von Patienten mit Verzicht auf eine sekundare Rekonstruktion nach infektbedingtem Totalverlust dar. Sieben Patienten mit Achillessehnendefekt nach auswartigen Rekonstruktionsversuchen erhielten eine Weichteildeckung ohne Sehnenrekonstruktion. Durchschnittlich 11 Monate postoperativ erfolgte eine Evaluation der Sprunggelenksfunktion u.a. durch den AOFAS-Score und isokinetische Kraftmessungen mit dem Biodex®-System. Alle Patienten zeigten hohe Mobilitat und Kraftentfaltung der unteren Extremitat. Der AOFAS-Score betrug 84,7 (max. 100), die Kraftabnahme fur Plantarflexion 44,5% verglichen zur Gegenseite und entsprach damit Ergebnissen nach sekundaren Sehnenrekonstruktionen. Nach Totalverlust der Achillessehne bestehen kompensatorische Mechanismen, die, verglichen mit Ergebnissen nach sekundaren Sehnenrekonstruktionen, einen groseren Kraftverlust verhindern und neben regularen Alltagstatigkeiten sogar Spitzensport erlauben. more...

The surgical management of defects in the pelvic region is a great surgical challenge. Primary tumor recurrences have to be addressed and local infections require appropriate therapy such as rigorous debridement and antibiotic therapy. Plastic surgery provides tissue reconstruction by well perfused flaps and also reestablishment of anatomic structures in the ano-genital region. An early reconstruction also reduces the wound complications of adjuvant or post oncologic therapy and reduces the rate of wound healing problems. more...

Sowohl Trauma als auch Lipome sind im klinischen Alltag weitverbreitet. Obwohl Lipome klinisch und pathologisch als gutartige Fettgewebstumoren definiert sind, besteht uber deren genaue Atiologie noch immer Unklarheit. In der vorliegenden Studie wurden 19 Patienten unseres Patientengutes mit 23 posttraumatischen Pseudolipomen retrospektiv anhand von Anamnese, sonographischer und magnetresonanztomographischer Diagnostik, Laborparametern und histopathologischer Untersuchungen analysiert. Das Durchschnittsalter der Patienten betrug 50,5 Jahre (±15,5). Das zugrunde liegende Trauma lag durchschnittlich 2,6 Jahre zuruck. 16 der 19 Patienten gaben anamnestisch ein groses, ausgedehntes, lange vorhandenes posttraumatisches Hamatom an. 9 der 23 Pseudolipome fanden sich an der oberen Extremitat, 3 an der unteren Extremitat, 9 am Stamm und 2 im Gesicht. Alle Tumoren lagen epifaszial. In 22 Fallen wurden die Pseudolipome exzidiert und in einem Fall durch eine Aspirationslipektomie entfernt. Die histologische Untersuchung des entfernten Gewebes ergab in 19 Fallen gekapselte und 4 Fallen ungekapselte gutartige Fettgewebstumoren. Der durchschnittliche Bodymassindex (BMI) betrug 29 kg/m2. Durch die Entfernung der Tumoren konnte bei allen Patienten ein gutes asthetisches Ergebnis erreicht werden. Der Zusammenhang zwischen einem stumpfen Weichteiltrauma und der Entstehung von posttraumatischen Lipomen wird noch immer kontrovers diskutiert, wobei zwei mogliche zugrundeliegende Pathomechanismen favorisiert werden: 1. Die Entstehung eines „Pseudolipoms“ in Folge eines Prolapses von Fettgewebe als unmittelbare Traumafolge und 2. die Lipomentstehung durch Differenzierung von Praadipozyten als Folge des Einflusses von Zytokinen, die durch ein posttraumatisches Hamatom freigesetzt werden. Es scheint einen Zusammenhang zwischen einer erhohten partiellen Thromboplastinzeit (PTT) und der Ausbildung von posttraumatischen Lipomen zu geben. Fur die Erklarung der Lipomentstehung durch den Prolaps von Fettgewebe spricht die generalisierte Vermehrung des Korperfettes, die durch den erhohten Body-Mass-Index dokumentiert wird. Die Entstehung posttraumatischer Pseudolipome kann multifaktoriell bedingt sein und ist schwer durch einzelne isolierte Pathomechanismen zu erklaren. more...

UNLABELLED Moist wound treatment is a well recognized method for the treatment of aseptic acute and chronic wounds. While the moist environment is beneficial to the woundhealing process, it also increases the risk of bacterial superinfection. We here report on the results of a clinical phase-III-study in which we tested the effect of a new PVP-iodine liposomal hydrogel (Repithel) on split-thickness skin grafts. This formulation optimizes moist wound treatment by improving the cell proliferation rate while preventing wound infection. AIM The aim of this phase-III-study was to analyse the efficacy and tolerance of Repithel in patients receiving meshed skin grafts. METHODS 167 patients with transplantation wounds were either treated with lipid gauze alone (control group) or with lipid gauze and Repithel. In both groups the extent of neoepithelization, the frequency and severity of graft losses and the time until complete wound closure was achieved were determined. Analysis of the re-epithelization was achieved by photoplanimetry. Impedance measurements gave additional information on the regeneration of the epidermal barrier. RESULTS Wounds receiving Repithel showed a significantly faster neoepithelisation than wounds which were treated with lipid gauze alone. Treatment with Repithel significantly reduced both the number of graft losses and the size of area lost. The time until wounds were closed completely was significantly shorter in patients receiving Repithel than in controls. The positive effects of Repithel on wound healing were especially observed in smokers, patients with chronic wounds, burns or infected wounds. CONCLUSIONS Repithel supports healing of meshgraft transplants and reduces the risk of graft loss. Patients who heal poorly benefit particularly from the Repithel treatment. more...

Antimikrobielle Peptide sind naturlich vorkommende kationische Peptidmolekule. Die erste Verteidigungslinie der Verbrennungswunde stellt das angeborene Immunsystem dar, deren Bestandteile diese Peptide sind. Um die topische Anwendbarkeit in infizierten Verbrennungswunden zu vereinfachen wurde die Wirksamkeit in Fibrinkleber in vivo und in vitro getestet. Nach In-vitro-Testung erhielten 15 mannliche Sprague-Dawley-Ratten eine tief zweitgradige Verbrennung, wurden mit multiresistenten Pseudomonas aeruginosa infiziert und mit Protegrin-1 (PG-1; 100 μg/ml, n=5), Fibrinkleber (n=5) oder einem Gemisch aus beiden (n=5) topisch behandelt, die Wirkung wurde zuvor durch einen Radial-Diffsusions-Assay bestatigt; 24 h spater wurde die verbrannte und infizierte Haut gewonnen und die Bakterienanzahl pro Gramm Haut bestimmt.

Background: Various standardized and/or validated models exist to test wound healing products. This article discusses their usefulness in clinical practice. Objectives: Major barriers to wound healing have been identified after intense interaction of research and practitioners. Although extensively tested, wound healing products are still associated with trial and error due to the high variability and complexity associated with the treatment of wounds. Therefore, the results of preclinical testing are compared and contrasted with clinical observations of a liposomal hydrogel containing 3% povidone-iodine (Repithel®, PVP-ILH) to assess their expressiveness and to give the practitioner more guidance in application. Methods: Testing of PVP-ILH included physicochemical testing according to ISO norms, testing in in vitro and in vivo models. The obtained results are compared to the clinical profile of the obtained product in randomized controlled trials and ultimately expressive case studies. Results: PVP-ILH displays good local tolerance, the basis for use in sensitive and predamaged tissue. As observed in laboratory testing, it readily provides moisture and takes up limited amounts of moisture. This was also seen in the clinical testing, as the ability to keep wounds moist and incorporate a certain – but not large – amount of exudates. Clinical results also show clean, well-debrided wounds, an effect that (in the absence of an established model for wound cleansing) was traced to the hydrogel component carbomer. Discussion: Recent consensus advocates the concept of wound bed preparation as a systematic approach to removing barriers to healing (TIME). Based on the results, tissue (removing non-viable tissue and debris) and moisture (balance) can now be better understood, and infection/inflammation (control) and edge (progressing, non-advancing or undermining wound edges) are reviewed together with previously published data to assess all aspects potentially impeding wound healing. Conclusion: PVP-ILH successfully removes barriers to wound healing, thus laying the foundation to high-quality wound closure. Results from many scientific disciplines can help the user to better understand a product, standardization of testing is the only way of making results comparable. more...

Extensive locoregional recurrency or metastatic involvement of brachial plexopathy is a condition that is often associated with advanced systemic breast cancer. In the past the role of surgeon was restricted due to a scepticism as to whether any benefit will be provided for the patient. In the recent 25 years however safe and refined plastic surgical approaches have been developed that provide more options to treat even complex recurrent disease. The strategy of plastic surgery in an interdisciplinary approach of gynecology, oncology and radiotherapy as well as thoracic surgery is outlined. more...

The success of a free flap transplantation is based on a sufficient microanastomosis which meets the following requirements: a pedicle placed without kinking or twisting, a good drainage, a well defined recipient vessel and integrity of the endothelium. The aim of this study was to determine whether operation-related ischaemia through flap transplantation and tourniquet induces an increase of Endothelin-1 plasma levels as one cause of vasospasm during microvascular procedures. We focused our attention in particular on the reperfusion period which is often limited to an irreversible perfusion failure of microcirculation due to free radicals, interleukin and Endothelin-1. Twenty-one patients with tissue injury of the lower leg were included in our study, fourteen underwent a latissimus dorsi muscle transplantation with a combined ischaemia, seven patients had a tourniquet ischaemia for tumour resection, debridement and local flap transfer. The duration of ischaemia varied due to the course of operation. The withdrawal of venous blood via central vein catheter, flap vein and wound bed followed a fixed time table pre- and post-reperfusion (T1: preoperative day via cubital vein, T2: 6th postoperative day, T3: 5 min, T4: 10 min, T5: 15 min, T6: 1 h post-declamping and after tourniquet ischaemia via central vein catheter and T7: within 5 min from the flap vein immediate after recharging the flap). The vessel anastomosis determined the withdrawal from the local wound bed. ET-1 in venous blood samples were measured with ELISA. The duration of ischaemia in the tourniquet group ranged from 22 min up to 210 min with a mean of 76.58 min and in the latissimus group from 87 min up to 203 min with a mean of 139.21 min. The mean ET-1 plasma concentration measured systemically before operation in the 21 patients was 0.51 +/- 0.08 pg/ml (Mean +/- SD). This result corresponds with data published in literature. The locally measured plasma levels of ET-1 after tourniquet and flap ischaemia were increased with 0.34 up to 3.90 pg/ml (0.95 +/- 0.79 pg/ml [Mean +/- SD]) for the tourniquet group and with 0.34 up to 14.87 pg/ml (1.85 +/- 3.64 pg/ml [Mean +/- SD]) for the latissimus group. This is an increase compared to systemically measured values as 0.75 +/- 0.06 pg/ml (Mean +/- SD) for the tourniquet group and 0.58 +/- 0.21 pg/ml (Mean +/- SD) for the latissimus group. We conclude that Endothelin-1 is increased locally in the early reperfusion period after free latissimus dorsi-transplantation. more...

Resektion und multimodale Therapie bosartiger Tumoren im Bereich der Beckenregion hinterlassen nicht selten ausgedehnte Defekte. Hierbei stellt die Nachbarschaft zum Rektum sowie auserem und innerem Genital ein groses Problem dar, lasst sich eine R0-Resektion oft nur durch Mitnahme entsprechender Strukturen erreichen. Durch resultierende Weichgewebsdefekte werden die Sitz- und Liegefahigkeit beeintrachtigt. Chronische Wunden und instabile Narben fuhren zu einer weiteren Belastung der Lebensqualitat dieser Patienten. Die plastisch-rekonstruktive Chirurgie bietet die Moglichkeit der suffizienten Weichteilrekonstruktion, um zum einen Patienten fruher zu rehabilitieren oder aber eine notwendige Strahlentherapie fruher einleiten zu konnen. more...

BACKGROUND AND PURPOSE Reconstruction of tendon tissue is problematic in many cases. Since direct tendon suture is often impossible, major reconstruction with the use of free tendon transplants or tendon transposition is necessary. Important motor units often have to be sacrificed for reconstructive purposes. In this study we investigated whether long tendon-like substitutes can be fabricated in vitro from human mesenchymal stem cells (MSCs) and a collagen type I gel when cultured under cyclic stretching conditions. MATERIAL AND METHODS MSCs were obtained from bone marrow aspirates of the iliac crest. Cells were suspended in a collagen type I gel and polymerized in a glass-cylinder with defined size. The fabricated tendon substitutes underwent static stretching for 14 days followed by cyclic stretching for 21 days in a special manufactured bioreactor. Non-stretched substitutes served as a control. RESULTS Macroscopically the stretched tendon substitutes showed an increased opacity and a smoother surface structure compared to the non-stretched control. The stretched substitutes displayed more spindle-shaped, longitudinal orientated cells, a tendon-like organization of the collagen matrix, and a parallel organization of the collagen fibers when stained with Hematoxylin/Eosin and Elastica. CONCLUSION Long tendon substitutes could be fabricated from MSCs and a collagen type I gel by cyclic stretching and showed tendon-like parallel collagen fibers and spindle-shaped cells. The use of MSCs in combination with adequate scaffold materials has great therapeutic potential for the development of autologous transplantable tendon substitutes. more...

On January 1st 2004, a new contract between the government, health insurance services, and hospitals was inaugurated in Germany. The aim of the contract is to decrease costs for surgical therapies by abolishing or at least minimizing hospitalization of patients. Hand surgery is widely affected by the new contract, since a very large part of surgical therapies for the hand was declared to be compulsory outdoor and another major part to be preferable outdoor. The surgeon may decide whether a patient needs inpatient or outpatient treatment but has to justify his decision. Hospitals and surgical clinics are both allowed to offer outpatient hand surgery and get the same payment under the same regulations. For most hospitals, structural changes will be necessary to offer outpatient surgery without financial loss. In our experience a personal and regular contact between patient and surgeon is most necessary for the best surgical result. Many of the compulsory outpatient operations in hand surgery can be done sufficiently and at high standard. This may not be the case for the second group to be handled not compulsory outdoor. The new contract allows hospitals to offer postoperative care for only 14 days, whereas many specific hand surgical procedures will need the surgeon's control and care for a much longer time. On the other hand, clinics and general practitioners have strict limitations for the prescription of hand therapies. We believe that the quality of hand surgery is highly dependent on sufficient postoperative treatment. If the postoperative care is neglected or restricted, secondary costs such as sick leave will increase. more...
