Abstract
The aim of this article is to present the importance of a structured and situation-adapted approach based on the diagnostic and therapeutic strategy in the interdisciplinary treatment of 54 patients with deep sternal wound infections (DSWI) after cardiac surgical interventions and the results achieved. The patients were 41 men and 13 women with an average age of 65.1 years, who developed a DSWI after a cardiac surgical intervention during the period 2003-2016. The treatment strategy included a thorough debridement including the removal of indwelling foreign material, the reconstruction with a stable re-osteosynthesis after overcoming the infection and if necessary, situation-related surgical flaps for a defect coverage with a good blood supply and mandatory avoidance of dead spaces. A total of 146 operations were necessary (average 2.7 operations/patient, range 1-7 operations). In 24.1 % of the cases a one-stage approach could be carried out. In 41 patients negative pressure wound therapy (NPWT) with programmed sponge changing was used for wound conditioning (mean 5 changes, standard deviation, SD± 5.6 changes over 22 days, SD± 23.9 days, change interval every 3-4 days in 40.7% of the cases). In 33 patients a bilateral myocutaneous pectoralis major flap was used, in 4 patients a vertical rectus abdominis myocutaneous (VRAM) flap and in 7 patients both were carried out. A total of 43 osteosynthesis procedures were carried out on the sternum with fixed-angle titanium plates. Of the patients 7 died during intensive care unit treatment (total mortality 13 %, n = 5, 9.3 % ≤ 30 days) or in the later course. Of the patients 47 (87.1 %) could be discharged with a cleansed infection. In 2 patients the implant was removed after 2 years due to loosening.

Abstract
The standard surgical procedure for complex calcaneal fractures is open reduction, internal reduction and internal stable angle plate osteosynthesis via a lateral approach. More recently, options for minimally invasive and percutaneous surgical strategies have been presented [4, 7]. As a possible procedural alternative for a covered, surgical treatment of calcaneal fractures, calcaneoplasty is discussed and applied in this context [5]. In this case series of five complex calcaneal fractures presented here, a balloon catheter was used for percutaneous reduction to restore the alignment of the calcaneus.This was followed by placement of PMMA cement in radiofrequency application and osteosynthesis using percutaneous cannulated screws. This Vicenti technique allows stable reduction and retention with early partial weight bearing with an overall low complication rate [17].

Abstract
BACKGROUND Impaired posttraumatic bone healing is a relevant complication of fractures. Usually, the standard treatment is surgical revision. For about 30 years extracorporeal shockwave therapy (ESWT) has emerged as an alternative treatment option with similar consolidation rates but less complications. OBJECTIVE This article aims to present our data in context to the current literature MATERIAL AND METHODS: From 2007 to 2016 a total of 97 patients diagnosed with impaired posttraumatic bone healing were treated with ESWT. Clinical and demographic data of this population were retrieved and analyzed retrospectively. RESULTS The general consolidation rate was 60.8%. Multiple variables were analyzed. A preinterventional bone gap ≥ 5 mm, initial dislocation > ½ of the bone shaft, nicotine consumption and a long time span from fracture to ESWT (> 6 months) were found as factors which significantly impair bone healing after ESWT. CONCLUSION ESWT is a safe and promising alternative treatment option for delayed unions. Regarding risk factors of a poor outcome may be identified before and increase the rate of success.

Status quo of the use of DCS concepts and outcome with focus on blunt abdominal trauma : A registry-based analysis from the TraumaRegister DGU®. Langenbecks Arch Surg 2021; 407:805-817. [PMID: 34611749 DOI: 10.1007/s00423-021-02344-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Accepted: 09/28/2021] [Indexed: 10/20/2022]
Abstract
INTRODUCTION Damage control surgery (DCS) is a standardized treatment concept in severe abdominal injury. Despite its evident advantages, DCS bears the risk of substantial morbidity and mortality, due to open abdomen therapy (OAT). Thus, identifying the suitable patients for that approach is of utmost importance. Furthermore, little is known about the use of DCS and the related outcome, especially in blunt abdominal trauma. METHODS Patients recorded in the TraumaRegister DGU® from 2008 to 2017, and with an Injury Severity Score (ISS) ≥ 9 and an abdominal injury with an Abbreviated Injury Scale (AIS) score ≥ 3 were included in that registry-based analysis. Patients with DCS and temporary abdominal closure (TAC) were compared with patients who were treated with a laparotomy and primary closure (non-DCS) and those who did receive non-operative management (NOM). Following descriptive analysis, a matched-pairs study was conducted to evaluate differences and outcomes between DCS and non-DCS group. Matching criteria were age, abdominal trauma severity, and hemodynamical instability at the scene. RESULTS The injury mechanism was predominantly blunt (87.1%). Of the 8226 patients included, 2351 received NOM, 5011 underwent laparotomy and primary abdominal closure (non-DCS), and 864 were managed with DCS. Thus, 785 patient pairs were analysed. The rate of hepatic injuries AIS > 3 differed between the groups (DCS 50.3% vs. non-DCS 18.1%). DCS patients had a higher ISS (p = 0.023), required more significant volumes of fluids, more catecholamines, and transfusions (p < 0.001). More DCS patients were in shock at the accident scene (p = 0.022). DCS patients had a higher number of severe hepatic (AIS score ≥ 3) and gastrointestinal injuries and more vascular injuries. Most severe abdominal injuries in non-DCS patients were splenic injuries (AIS, 4 and 5) (52.1% versus 37.9%, p = 0.004). CONCLUSION DCS is a strategy used in unstable trauma patients, severe hepatic, gastrointestinal, multiple abdominal injuries, and mass transfusions. The expected survival rates were achieved in such extreme trauma situations.

Abstract
Zusammenfassung
Hintergrund
Die unkontrollierte Blutung ist weiterhin eine führende potenziell vermeidbare Todesursache im Rahmen schwerer Verletzungen.
Ziel der Arbeit
Die vorliegende Arbeit hat zum Ziel, die Vorbereitung für eine differenzierte Hämotherapie im Rahmen der Schwerstverletztenbehandlung in Kliniken verschiedener Versorgungsstufen innerhalb der Struktur des TraumaNetzwerks der Deutschen Gesellschaft für Unfallchirurgie (DGU)® zu evaluieren.
Material und Methoden
Anhand einer Online-Umfrage wurden gezielt Diagnose- und Therapiestrategien sowie vorhandene Ressourcen innerhalb der Kliniken erfragt. Im Rahmen einer Subgruppenanalyse sollte festgestellt werden, ob es Unterschiede in Bezug auf infrastrukturelle Voraussetzungen und diagnostisches bzw. therapeutisches Vorgehen innerhalb der Versorgungsstufen des TraumaNetzwerks DGU® gibt.
Ergebnisse
Massivtransfusionsprotokolle (MTP) bestehen in 75 % der Kliniken. Die Aktivierung erfolgt i. d. R. durch den Trauma-Leader (62 %). In 63 % erfolgt die Aktivierung aufgrund einer Anforderung aus der Präklinik. Als Transfusionstrigger werden ein positives FAST (80 %) und ein Pulsdruck < 45 mm Hg (60 %) angegeben. In 50 % der Kliniken existiert kein starres Transfusionsverhältnis der einzelnen Blutkomponenten. Überregionale Traumazentren (ÜTZ) bekommen im Vergleich zu regionalen Traumazentren (RTZ) und lokalen Traumazentren (LTZ) angeforderte Blutprodukte frühzeitiger (p 0,025).
Diskussion
Der massive Blutverlust ist ein seltenes Ereignis, welches mit einer hohen Letalität vergesellschaftet sein kann. MTP bilden die Grundlage für eine frühe Therapie der traumainduzierten Koagulopathie und tragen zur Verbesserung der Überlebenschancen der Patienten bei. Es existiert ein deutlicher Unterschied in den diagnostischen und therapeutischen Möglichkeiten in den einzelnen Versorgungsebenen. ÜTZ verfügen mehrheitlich über die umfangreichsten Optionen, gefolgt von RTZ und LTZ.

Abstract
Objective:
The number of subtrochanteric femoral fractures will continue to grow on account of demographic developments. The treatment of choice is reduction and surgical stabilisation. Intramedullary (IO) and extramedullary (EO) techniques are available for this purpose. A final assessment has not been made of which technique is superior with regard to treatment outcome, complication rates, and revision rates. The objective of this retrospective study was to compare surgical procedures with regard to weight bearing, length of hospital stay, the occurrence of complications, and the necessity of surgical revisions.
Methods:
This retrospective study included 77 patients (74.9 ± 14.9 years; 42.9% male). Associations between surgical procedures and treatment outcomes, complications and revision rates were calculated by linear and logistic regression analysis. To investigate the effect of surgical procedure within patients with fracture type 2 B according to Russel-Taylor classification, a subgroup analysis was performed.
Results:
In case of fracture type 2 B, according to Russell-Taylor classification, EO took 80 minutes longer on average than the intramedullary technique (p = 0.001), although surgeon experience plays an important role. Common complications were more frequently associated with IO than with EO. Surgical revisions were required more often in the extramedullary group (OR 4.5; 95% CI: 0.87 – 23.19). Patients in the intramedullary group were discharged 3.4 days earlier from the hospital (p = 0.024). Older patients had a higher risk for the occurrence of complications, but BMI and the experience of the surgeon did not. Patients with intramedullary stabilisation frequently showed better postoperative weight-bearing stability.
Conclusion:
The intramedullary technique offers advantages to both patients and hospitals with regard to outcome, duration of surgery, and length of stay in the hospital. Although, extramedullary implants are less expensive, this advantage is clearly reduced by the longer duration of surgery and hospital stays.

Abstract
PURPOSE The mortality rate for severely injured patients with the injury severity score (ISS) ≥16 has decreased in Germany. There is robust evidence that mortality is influenced not only by the acute trauma itself but also by physical health, age and sex. The aim of this study was to identify other possible influences on the mortality of severely injured patients. METHODS In a matched-pair analysis of data from Trauma Register DGU®, non-surviving patients from Germany between 2009 and 2014 with an ISS≥16 were compared with surviving matching partners. Matching was performed on the basis of age, sex, physical health, injury pattern, trauma mechanism, conscious state at the scene of the accident based on the Glasgow coma scale, and the presence of shock on arrival at the emergency room. RESULTS We matched two homogeneous groups, each of which consisted of 657 patients (535 male, average age 37 years). There was no significant difference in the vital parameters at the scene of the accident, the length of the pre-hospital phase, the type of transport (ground or air), pre-hospital fluid management and amounts, ISS, initial care level, the length of the emergency room stay, the care received at night or from on-call personnel during the weekend, the use of abdominal sonographic imaging, the type of X-ray imaging used, and the percentage of patients who developed sepsis. We found a significant difference in the new injury severity score, the frequency of multi-organ failure, hemoglobine at admission, base excess and international normalized ratio in the emergency room, the type of accident (fall or road traffic accident), the pre-hospital intubation rate, reanimation, in-hospital fluid management, the frequency of transfusion, tomography (whole-body computed tomography), and the necessity of emergency intervention. CONCLUSION Previously postulated factors such as the level of care and the length of the emergency room stay did not appear to have a significant influence in this study. Further studies should be conducted to analyse the identified factors with a view to optimising the treatment of severely injured patients. Our study shows that there are significant factors that can predict or influence the mortality of severely injured patients.

Abstract
Due to recent rampage and terror attacks in Europe, gunshot wounds have become a focus of attention even though they are still rare in Europe. Approximately 50% of gunshot wounds affect the extremities and to understand the sequelae, a basic knowledge of wound ballistics is indispensable. The energy transmitted from the bullet to the tissue is responsible for the severity of the injury and is dependent on the type of weapon and ammunition. A differentiation is made between low-energy injuries caused, e.g. by pistols and high-energy injuries mostly caused by rifles. The higher energy transfer to the tissue in high-energy injuries, results in a temporary wound cavity in addition to the permanent wound channel with extensive soft tissue damage. High-energy gunshot fractures are also more extensive compared to those of low energy injuries. Debridement seems to be necessary for almost all gunshot wounds. Fractures should be temporarily stabilized with an external fixator due to contamination.

Abstract
Due to the recent terrorist attacks in Paris, Brussels, Ansbach, Munich, Berlin and more recently Manchester and London, terrorism is realized as a present threat to our society and social life, as well as a challenge for the health care system. Without fueling anxiety, there is a need for sensitization to this subject and to familiarize all concerned with the special kind of terrorist attack-related injuries, the operational priorities and tactics and the individual basic principles of preclinical and hospital care. There is a need to adapt the known established medical structure for a conventional mass casualty situation to the special requirements that are raised by this new kind of terrorist threat to our social life. It is the aim of this article, from a surgical point of view, to depict the tactics and challenges of preclinical care of the special kind of terrorist attack-related injuries from the site of the incident, via the advanced medical post or casualty collecting point, to the triage point at the hospital. The special needs of medical care and organizational aspects of the primary treatment in the hospital are highlighted and possible decisional options and different approaches are discussed.

Abstract
The incidence of terrorist attacks is increasing worldwide, and they have also become a permanent threat in European cities. Due to its complexity, terrorist attack trauma places high demands on the strategy of surgical treatment. The combination of various mechanisms, explosions and gunshot injuries, with the characteristic pressure (blast) damage and a high proportion of penetrating trauma with simultaneous burns are characteristic features. Unlike in military conflicts, injuries to people of all ages and without ballistic body protection (body armor) are to be expected. The mechanism of the attack and its local conditions are of relevance for the assessment of the situation and the expected injury patterns. Thus, suicide attacks result in several times higher numbers of fatalities and casualties. Explosions on free ground lead to different types of injury than those in closed or semi-enclosed spaces. The treatment principles of the Advanced Trauma Life Support (ATLS®) are based on the intrahospital care of casualties as well as damage control strategies with trigger factors. In order to prepare and educate clinics and surgeons in Germany for such scenarios, various course formats of the professional societies, the German Society for General and Visceral Surgery (DGAV) and the German Society for Trauma Surgery (DGU) have now been established.

The First Aid and Hospital Treatment of Gunshot and Blast Injuries. DEUTSCHES ARZTEBLATT INTERNATIONAL 2018; 114:237-243. [PMID: 28446350 DOI: 10.3238/arztebl.2017.0237] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/10/2016] [Revised: 08/10/2016] [Accepted: 01/24/2017] [Indexed: 02/05/2023]
Abstract
BACKGROUND When gunshot and blast injuries affect only a single person, first aid can always be delivered in conformity with the relevant guidelines. In contrast, when there is a dynamic casualty situation affecting many persons, such as after a terrorist attack, treatment may need to be focused on immediately life-threatening complications. METHODS This review is based on pertinent publications retrieved by a selective search in Medline and on the authors' clinical experience. RESULTS In a mass-casualty event, all initial measures are directed toward the survival of the greatest possible number of patients, in accordance with the concept of "tactical abbreviated surgical care." Typical complications such as airway obstruction, tension pneumothorax, and hemorrhage must be treated within the first 10 minutes. Patients with bleeding into body cavities or from the trunk must be given priority in transport; hemorrhage from the limbs can be adequately stabilized with a tourniquet. In-hospital care must often be oriented to the principles of "damage control surgery," with the highest priority assigned to the treatment of life-threatening conditions such as hemodynamic instability, penetrating wounds, or overt coagulopathy. The main considerations in initial surgical stabilization are control of bleeding, control of contamination and lavage, avoidance of further consequences of injury, and prevention of ischemia. Depending on the resources available, a transition can be made afterward to individualized treatment. CONCLUSION In mass-casualty events and special casualty situations, mortality can be lowered by treating immediately life-threatening complications as rapidly as possible. This includes the early identification of patients with lifethreatening hemorrhage. Advance preparation for the management of a masscasualty event is advisable so that the outcome can be as favorable as possible for all of the injured in special or tactical casualty situations.

Abstract
ZusammenfassungAuch in Deutschland wurden in jüngster Zeit Anschläge mit terroristischem Hintergrund durchgeführt, waren geplant oder konnten nur knapp vereitelt werden. Diese Tatsache führt die Notwendigkeit vor Augen, eine entsprechende Expertise zur Versorgung von Schuss- und Explosionsverletzungen vorzuhalten. Die Daten zur Versorgung von Schuss- und insbesondere aber Explosionsverletzungen stammen häufig aus Krisen- und Kriegsregionen. Eine Vergleichbarkeit mit zivilen Terroranschlagtraumata ist durch den bei Soldaten vorhandenen ballistischen Körperschutz (Schutzwesten, Body Armour) nur schwer möglich.
Methodik Es wurden die Daten der Patienten, die im deutschen Militärhospital Mazar-e Sharif bei Schuss- oder Explosionsverletzungen versorgt wurden, aus den Jahren 2009 – 2013 analysiert. Einschlusskriterien waren penetrierende Verletzungen des Thorax bzw. des Abdomens. Zur besseren Vergleichbarkeit mit zivilen Anschlagsszenarien wurden ausschließlich zivile Patienten ohne ballistischen Körperschutz einbezogen.
Ergebnisse Von den 117 Patienten waren 58 von Schuss- und 59 von Explosionsverletzungen des Thorax oder Abdomens betroffen. 60% der Patienten hatten eine Thorax-, 69% eine Abdominal- und 25,6% eine thorakoabdominelle Verletzung, wobei die Explosionsverletzten signifikant mehr Thoraxverletzungen aufwiesen. Abdominell waren Leber-, Dünndarm- und Kolonverletzungen in der Anzahl führend. Bei den Explosionsverletzten fanden sich sowohl signifikant mehr Verletzungen als auch ein im Mittel mit 29 signifikant höherer Injury Severity Score (ISS). 26% der Schuss- und 41% der Explosionsverletzten wurde durch Damage Control Surgery (DCS) erstversorgt. Schussverletzungen hatten trotz niedrigerem ISS keine geringere Anzahl an Operationen pro Patient. Die mit 25,7% höchste Mortalität wiesen Patienten mit thorakoabdominellen Kombinationsverletzungen auf (vs. 8,3% bei isoliert thorakal und 8,7% isoliert abdominell). Die Gesamtmortalität betrug 13,7% (10,3% nach Schuss-, 16,7% nach Explosionsverletzung). Die verstorbenen Patienten wiesen mit 32,9% einen signifikant erhöhten ISS-Wert auf.
Schlussfolgerung Explosionsverletzte ohne ballistischen Schutz des Torsos weisen vor allem für thorakoabdominelle Verletzungen eine hohe Mortalität auf. Explosionsverletzungen können häufiger zur DCS-Indikation führen. Die Versorgung von Schuss- und Explosionsverletzten setzt die Kenntnis und Kompetenz zur Durchführung von Damage-Control-Prozeduren des Thorax und des Abdomens voraus.

Abstract
UNLABELLED Thumb carpometacarpal joint replacement is associated with high rates of loosening and failure. We present our results for an uncemented ceramic-ceramic total joint prosthesis with a reverse ball-and-socket design and bioactive coating. Between 2008 and 2012, 29 prostheses were inserted into 28 patients (mean age 63 years) with advanced osteoarthritis. After a mean period of 33 months (range 9-62), 26 patients (27 implants) were available for follow-up. Six months postoperatively, 50% of the patients had radiological evidence of early loosening. Fifteen implants had been removed in 14 patients for aseptic loosening (13) or trapezium fracture (2). The 12 patients whose prosthesis was still in place had a mean visual analogue scale pain score of 1.9 (range 0-6) and a mean Disabilities of the Arm, Shoulder and Hand score of 23 (range 0-73.3). Eleven patients were satisfied with the procedure. The rate of early aseptic failure was unacceptably high. LEVEL OF EVIDENCE IV.

Does the presence of an emergency physician influence pre-hospital time, pre-hospital interventions and the mortality of severely injured patients? A matched-pair analysis based on the trauma registry of the German Trauma Society (TraumaRegister DGU ®). Injury 2017; 48:32-40.

Abstract
PURPOSE The role of emergency physicians in the pre-hospital management of severely injured patients remains controversial. In Germany and Austria, an emergency physician is present at the scene of an emergency situation or is called to such a scene in order to provide pre-hospital care to severely injured patients in approximately 95% of all cases. By contrast, in the United States and the United Kingdom, paramedics, i.e. non-physician teams, usually provide care to an injured person both at the scene of an incident and en route to an appropriate hospital. We investigated whether physician or non-physician care offers more benefits and what type of on-site care improves outcome. MATERIAL AND METHODS In a matched-pair analysis using data from the trauma registry of the German Trauma Society, we retrospectively (2002-2011) analysed the pre-hospital management of severely injured patients (ISS ≥16) by physician and non-physician teams. Matching criteria were age, overall injury severity, the presence of relevant injuries to the head, chest, abdomen or extremities, the cause of trauma, the level of consciousness, and the presence of shock. RESULTS Each of the two groups, i.e. patients who were attended by an emergency physician and those who received non-physician care, consisted of 1235 subjects. There was no significant difference between the two groups in pre-hospital time (61.1 [SD 28.9] minutes for the physician group and 61.9 [SD 30.9] minutes for non-physician group). Significant differences were found in the number of pre-hospital procedures such as fluid administration, analgosedation and intubation. There was a highly significant difference (p<0.001) in the number of patients who received no intervention at all applying to 348 patients (28.2%) treated by non-physician teams and to only 31 patients (2.5%) in the physician-treated group. By contrast, there was no significant difference in mortality within the first 24h and in mortality during hospitalisation. CONCLUSION This retrospective analysis does not allow definitive conclusions to be drawn about the optimal model of pre-hospital care. It shows, however, that there was no significant difference in mortality although patients who were attended by non-physician teams received fewer pre-hospital interventions with similar scene times.

Abstract
The purpose of this study was to analyze the different causes of symptomatic osteoarthritis (OA) of the hip joint in active duty soldiers requiring a total hip arthroplasty and the hypothesis that soldiers had a reduced prevalence of secondary OA as a result of a selection process that has taken place through multiple medical assessments during their military career. We analyzed patient records from 2006 to 2012 for male patients ≤60 years with OA of the hip and indication for total hip arthroplasty in a military hospital in which civilian patients are also treated. About 44 military patients (MP) and 69 civilian patients (CP) were included. The prevalence of different causes of OA of the hip did not differ significantly in both groups (primary OA MP: 59.1% [n = 26], CP: 56.5% [n = 39]; dysplasia MP: 25.0% [n = 11], CP: 24.6% [n = 17]; femoral head necrosis MP: 11.4% [n = 5], CP: 13% [n = 9]; post-traumatic OA MP: 4.5% [n = 2], CP: 5.8% [n = 4]). In conclusion, recurrent medical assessments that are usually based alone on clinical examinations were not able to reduce the prevalence of prearthrotic deformities as a joint-specific risk factor for the development of symptomatic hip OA in our military collective.

BACKGROUND Gunshot wounds of the lower extremities are always serious injuries, especially in cases in which bone is affected. Contamination and extensive tissue damage can be life-threatening for the patient and severely affect the function of the extremity. Contamination and local infections with multidrug resistant pathogens are regularly encountered particularly in casualties evacuated from crisis regions. Treatment of this special type of injury, which differs in the form and extent from conventional high-energy trauma of the lower extremities, usually requires lengthy and extensive therapy algorithms in order to preserve the affected extremity. PATIENTS AND METHODS Based on the results of 34 gunshot wounds of the lower extremities which were surgically treated in this department between 2005 and 2011, this article reports on procedures used for wound management, soft tissue reconstruction and restoration of bone continuity. This group included 18 patients with a total of 20 gunshot-related fractures, 40% of which affected the lower leg and 35% the thigh. The affected extremities could be salvaged in all cases. RESULTS The therapeutic spectrum required for bone reconstruction after soft tissue coverage demonstrated in these case examples ranged from conventional osteosynthesis with or without local cancellous bone transplant with platelet-rich plasma, to healing in a fixator, bone resection and the Masquelet method, distraction osteogenesis using a fixator in order to restore continuity and definitive secondary extension using an intramedullary skeletal kinetic distractor (ISKD) nail. Out of 15 bullet fractures affecting large tubular bones 8 could be healed without any shortening, axis deviation or malrotation. In 7 cases definitive shortening by an average of 20 mm (minimum 10 mm and maximum 40 mm) was necessary. The average treatment time before full weight-bearing was achieved within tolerable pain limits was 66 weeks (minimum 4 weeks and maximum 267 weeks). Secondary osteitis and osteomyelitis following primary restoration was detected in only one case. CONCLUSION These results show that the treatment of gunshot wounds of the lower extremities is time-consuming and extensive and requires the complete spectrum of modern trauma surgery. Despite the high risk of complications during treatment it is possible and feasible to apply procedures that preserve the extremities.

Abstract
BACKGROUND Projectiles or metal fragments can remain lodged in the body of victims of gunshot injuries. This also applies to projectiles which do not tend to deform or fragment on impact. When a projectile fragments on penetration, jacket or lead core particles are likely to remain lodged in the affected region even if the projectile has exited the body. AIM OF THE STUDY A frequently asked question in the surgical management of such injuries is whether there are medical indications for the surgical removal of projectiles or fragments. MATERIAL AND METHODS This article presents some typical cases of patients who have received treatment at our institution and reviews the pertinent literature to show general recommendations in special cases concerning the removal of projectiles or fragments and when additional surgical trauma is justified. Parameters for decision making are presented in an algorithm. RESULTS From our own patients, 5 with remaining fragments in the soft tissue were invited for a clinical follow up. Serum probes and 24 h urine output was analysed for serum lead levels and urinary aminolevulinic acid levels. 74 months (max. 128 - min. 42 months) after injury we documented not elevated serum lead levels of 8.25 μg/ml and urinary aminolevulinic acid levels of 4.8 mg/24 h. DISCUSSION When lead-containing projectiles or fragments remain lodged in the body, monitoring is required and includes the measurement of serum lead levels and urinary aminolevulinic acid levels. The most important clinical symptoms of lead poisoning are gastrointestinal and neurological in nature. The treatment of choice for lead poisoning is the administration of chelating agents and removal of the lead source by surgical intervention.

Abstract
We report about a successful reconstruction of the first carpometacarpal joint (CMC-joint) of the right hand in a 23 years old man with a posttraumatic defect using the OATS-technique (Osteochondral Autologous Transfer System). 2 autologous osteochondral cylinders with matching surfaces were harvested from the knee joint and implanted in osteoarthritic areas of the CMC-1 joint surface in press fit technique. After primary healing clinical and radiological controls were assessed 6 and 12 weeks postoperatively. At clinical follow-up 1 year after the function of the CMC-1 joint was completely free, function nearly fully restored. The osteochondral grafts revealed a sound healing in an additional MRI-investigation. 3 years after the operation, the DASH-score of the patient was measured with 4.2 points. With view to the encouraging results of the OATS technique in other joints it should be taken into consideration in cases of osteoarthritic CMC-1 joint respecting indicatory limitations.

Abstract
Gunshot injuries to the hand are rare in Central Europe. As a result of their special trauma morphology they are a serious threat to the functional integrity of the hand and often lead to a loss of function which can be associated with a permanent unfitness to work or disability. Blast injuries to the hand are more common in this part of the world and are usually caused by the inappropriate use of fireworks. This trauma entity is associated with a number of special kinetic features and effects which have therapeutic consequences and should therefore be discussed separately. As a result of the low incidence of these specific types of injuries in times of peace, experience-based expertise is unlikely to be available. The management of gunshot injuries to the hand is a particular challenge to hand surgeons who must have specialist knowledge and skills in order to achieve an optimum outcome. This applies even more so to the treatment of blast injuries to the hand which are associated with far more complex injury patterns. As a rule blast injuries are associated with a high risk of complications and require a rapid assessment and rigorous management of all damaged structures similar to approaches used for infections of the hand. Illustrated by several cases which have been treated at our institution the basic aspects of the development and morphology of these injuries are discussed as well as different treatment options, algorithms and possible treatment outcomes.

A comparison of monocyte counts and ex vivo and in vitro monocyte cytokine production after major surgical trauma. J Surg Res 2008; 154:91-8.

Abstract
BACKGROUND Impaired function of cluster of differentiation 14-positive (CD14+) monocytes (MOs) after major surgical trauma is believed to predispose to infectious complications. Postoperative decreases in human leukocyte antigen (HLA)-DR expression, tumor necrosis factor-alpha (TNF-alpha) production and interleukin (IL)-12 synthesis have been reported. There are no studies comparing absolute MO counts and MO cytokine synthesis in peripheral blood and stimulated cultures. METHODS The study group included 10 low-risk patients undergoing elective cardiac surgery with extracorporeal circulation. Preoperatively (d0) and on the first (d1) and third (d3) postoperative d, we analyzed leukocyte counts, CD14+ MO absolute counts, HLA-DR expression, and stimulated IL-12 and TNF-alpha synthesis using flow cytometry. In addition, IL-12 and TNF-alpha release in stimulated whole blood cultures was assayed. RESULTS Whereas the absolute numbers of leukocytes and CD14+ MOs were significantly elevated, HLA-DR expression was suppressed postoperatively. The proportion of TNF-alpha- and IL-12-producing MOs was reduced after surgery. This, however, led to a significant postoperative decrease only in the absolute numbers of peripheral blood IL-12+ MOs. IL-12 secretion was postoperatively reduced in whole blood cultures. The IL-12-synthesizing capacity of IL-12+ MOs was significantly reduced only on d1. CONCLUSIONS The immediate postoperative period is associated with an increase in the absolute MO numbers and an impairment of MO function, which is reflected in a reduced capacity to synthesize IL-12 and TNF-alpha and a decreased ability to express HLA-DR and present antigens. Whereas the cytokine-producing capacity returns to normal levels on d3, the suppression of HLA-DR expression persists.

Abstract
Bomb attacks on the civilian population are one of the primary instruments of global terrorism. Confronted as we are with the increasingly real threat in Europe too, we now have to be constantly prepared for the mass casualties and new injury patterns in trauma care that are caused by terrorist bombings. This is extraordinarily challenging, on both medical and logistical levels, for the hospitals involved. In this review the basic mechanisms of blast injuries are clarified. In addition, the fundamental principles of triage and the management of multiple trauma are presented; these are oriented on ATLS (advanced trauma life support) and DCS (damage control surgery) guidelines. These treatment concepts, which have proved their worth in both military and civilian environments, involve ongoing triage and constant situational assessment and are the basis of improved treatment results in the care of multiply traumatized victims of terrorist bombings.

Abstract
Traumatic atlanto-axial rotatory fixation (AARF) is a relatively uncommon injury, especially in association with fractures of the axis. The rotatory dislocation and fixation is normally caused by intercalated facet joints of axis and atlas. A traumatic AARF in a 21 year old female is presented with special emphasis on the diagnostic and therapeutic approaches. This high velocity injury was caused by a traffic accident. The trauma service which was initially involved made the correct diagnosis and tried to reduce the dislocation by skull traction during analgesia and sedation, but without success. For further treatment, the patient was referred to a level one trauma center. After completing the diagnostic imaging with MRI and CT for exact delineation of the fracture site and determination of ligament damage, a halo fixation for skull traction was installed. This second attempt was also unsuccessful. Only a closed reduction under general anesthesia with muscle relaxation led to a neutral alignment and congruent joint contact between C1 and C2. Due to the stable fracture site and the intact ligaments, a conservative treatment with a stable collar splint was performed.

Abstract
BACKGROUND In cases of septic joint destruction, an unfavorable situation of soft tissues and chronic osteomyelitis are responsible for high failure rates of ankle fusions. We wanted to evaluate the control of infection and the fusion rate using hybrid external fixators for the fusion of the septic ankle in a prospective study. METHODS From 1996 to 1998, 15 arthrodeses were performed using hybrid external fixators. All patients had a combination of bone and soft tissue infections. Fourteen patients suffered from sequelae of posttraumatic osteoarthritis, and one patient suffered from rheumatoid arthritis. In 14 patients, pathogens could be identified; in 87%, Staphylococcus aureus was found. Eight patients had relevant concomitant diseases. RESULTS The preservation of limbs by solid tibiotalar fusion was achieved in 14 patients (93%). One patient maintained an infected pseudarthrosis. During the 12-month follow-up, three patients had a fistula that persisted, with two patients having a solid arthrodesis. Full weight-bearing was possible for all the patients with a successful fusion. Seventy-five percent of the patients that had not retired at the time of the study regained their fitness for work. CONCLUSION The hybrid external fixator presents a successful alternative for those arthrodeses of ankle joints where complications such as bone/joint infections or poor soft tissue conditions occur.

Abstract
BACKGROUND Although improved techniques of internal fixation and prosthetic replacement were introduced successfully in the field of operative fracture care, treatment of complex fractures of the proximal humerus also involving the humeral head remains to be a challenge to the trauma surgeon. We therefore investigated clinical and radiological long-term results after humeral head preserving procedures. METHODS 41 patients with a three or four part fracture of the humeral head were evaluated on average 6.6 years (min. 4.4 y; max. 9.0 y) after the trauma. The evaluation was based on the Constant- and HSS score clinically and on the Neer score radiologically. Nine patients were treated conservatively (group A), 13 patients had primarily an operative treatment (group B) and another 19 were operated upon after failure of conservative means. 24 of the patients were female and 17 male, with an average age of 52 years (min. 14.4 y; max. 71.2 y). According to Neers 's fracture classification of humeral head fractures we saw 14 type IV, 25 times a combination of type IV and V and in another 2 cases a type VI fracture. RESULTS In group A (conservative) the Constant score showed on average 82.0 points for the injured and 95.3 points for the contralateral shoulder, the HSS score revealed 73.6 points and Neer's x-ray score 5.6 points. Group B (operated) showed also good results on average according to a Constant score of 72.1 points (fractured humerus) compared with 98.1 points of the contralateral shoulder. HSS score was 64.7 points. The radiological results reached 4.0 points. Group C (conservatively failed, secondary operation) achieved 68.2 points for the injured side and 95.8 points for the contralateral side according to Constant and 59.5 points according to HSS score. The x-ray evaluation showed 5.3 points. Fracture type did not influence the outcome in any of the groups. There was no humeral head necrosis in group A, one in group B (2.4 %) and four in group C (9.8 %). CONCLUSION These data show that regarding to clinical and radiological long-term results also complex fractures of the humeral head should be treated by head preserving procedures.

Abstract
UNLABELLED Treatment of complex fractures of the humeral head remains an obviously unsolved problem. Under consideration of the problems of head preserving methods, the development of the last years tended towards the hemiprosthetic replacement. As the discussion about the methods and implants continues to be controversial, long-term results of Neer-II-replacement of humeral head in own trauma cases are presented here. PATIENTS AND METHODS 46 patients were investigated, in whom a cemented Neer II hemiprosthesis was implanted between 1983 and 1996 due to complex fracture patterns. Median age was 60.2 years, 74 % of patients were female. 59 % had a luxation fracture type Neer VI, 22 % presented a concomitant nerval lesion. Follow up was performed 5 years on average after the operation. 38 patients were investigated clinically according the score of Constant and Murley, 36 had a x- ray control. Additionally an individual questionnaire was completed by 46 patients. RESULTS Average Constant-score was 66.2 points, whereas in 76.3 % a satisfactory or better result was achieved. In 23.9 % the outcome was poor. In one patient (2.2 %) explantation of the hemiprosthesis and shoulder fusion due to pain was necessary. Conditions for a good result were a patient aged 50 years and younger (75.9 pts. versus 64.2 pts.), an early hemiprosthetic replacement within 4 weeks after the trauma (71.7 pts. versus 55.3 pts.) and a patient without an earlier operation and nerval lesion (76.8 pts. versus 53.9 pts.). No correlation was found between the date of the follow-up and the interval of time since the operation. CONCLUSION After complex fractures of the humeral head satisfactory long-term results can be obtained by the cemented Neer II hemiprosthesis. Thus, implants of the newer generation can not yet whitness their superiority under consideration of functional aspects. Refixation and reintegration of both the tubercula after trauma still seems to be an unsolved problem and requires further development.

Abstract
Detection of a bacterial arthritis of the shoulder represents an absolute indication for intervention. Irrespective of the cause of the infection, the most decisive prognostic factors are early diagnosis and therapy. We report on two patients who suffered from generalized sepsis and resulting death after delayed treatment of iatrogenic joint infections of the shoulder caused by intra-articular injection therapy. Both patients suffering from septic shock syndrome had been transferred to our hospital for surgical and intensive care treatment. They died in spite of maximal intensive care and aggressive surgical treatment. On the basis of the cases presented, it can be concluded that an acute infection of the shoulder joint must be excluded early when painfully limited range of motion in combination with clinical and laboratory signs of inflammation become apparent. Successful therapy of joint infection also requires early surgical treatment, including resection of infected tissue. If surgical joint revision is not performed or is performed too late, there is the risk of irreversible damage to the afflicted joint, even septic spread endangering the patient's life.

Abstract
Trauma surgery and orthopedic trauma surgery have been accompanied not only by internal quality assessment, but also by external quality assessment procedures right from the beginning. The reasons for these mechanisms were based on legal regulations of treatment of work-related accidents. In 1958, the Arbeitsgemeinschaft für Osteosynthese (Working Group on Osteosynthesis, AO group) was founded. The results of the AO's scientific activities built the basis of osteosyntheses. In 1988, legal regulations changed again in Germany. Since this reform of some important facets of public health care, each hospital or institution is committed to perform external and internal quality assessment. In addition, the introduction of a payment system based on diagnosis-related groups makes it necessary to install basic quality management systems within the next few years. This paper presents some well-established procedures, especially the diagnosis-related study in the whole district of Westphalia-Lippe. The aim of the study was a quality assessment of the treatment of intracapsular fractures of the collum of the femur. Problems in data analysis and interpretation are shown. Because of some grave problems, certain changes in the study design seem to be warranted. Despite these facts, however, we are convinced that we not only need this kind of quality assessment, but that we should try to expand these studies based on the experiences we gained.

Abstract
INTRODUCTION Persisting infections of the hip joint are regarded as one of the most feared complications following total hip arthroplasty or failed osteosynthetic treatment of fractures of the proximal femoral part. In these cases resection arthroplasty according to Girdlestone often is the ultimate treatment. METHODS Twenty-seven patients (11 men and 16 women) who had undergone resection arthroplasty according to Girdlestone could be included in this study. In all cases Girdlestone operations had been performed because of persisting infections of the hip joint. The mean follow-up was 7.1 years. RESULTS In 22 out of 27 cases (81.5%) eradication of the infection was finally achieved. At the time of re-evaluation 6 patients had no pain, 12 sometimes suffered from moderate pain, 7 from pain during physical activities and 2 patients experienced pain even at rest. At the time of follow-up, 11 patients used a cane, 14 patients needed two canes or crutches and in 2 cases a wheelchair was necessary. The mean shortening of the leg was 5.2 cm (range 3-15 cm). Clinical evaluation using the score according to Merle d'Aubigné and Postel to assess the functional results showed a mean of 6.7 points (range 2-10 points). Of our patients, 59.3 % were satisfied with the functional results obtained. CONCLUSION In the long run the Girdlestone procedure still seems to be a reasonable salvage operation for persisting deep infections following hip surgery.

Abstract
Beside of modern surgical and implant techniques and basic pathophysiological knowledge, internal fixation of subcapsular fractures of the neck of the femur is still known to be connected with a high rate of complications. Implant failure, the typical early complication arising within the first 3 months, non-union, avascular necrosis of the femoral head and late segmental collapse are the typical complications. The type of fracture, timing of operation (emergency operation), quality of reduction and implant positioning have all been shown to predict outcome significantly. However, it is also suggested that further therapeutical interventions like intra-articular pressure decrease by evacuation of hematoma, the kind and technique of reduction, special surgical techniques and postoperative treatment can influence outcome, as well as patient-associated factors like age, degree of osteoporosis, neurological disease, and alcoholism. The superiority of one of the 100 different existing implants have not been proved either by clinical or by biomechanical trials. However, besides screw osteosynthesis, the sliding screw plate and less often sliding nail plate implants are commonly used. Because of the very different biomechanical principles it is of great importance to adhere to the special operative techniques to avoid intraoperative complications that might cause treatment failure. To reduce the frequency of these almost always fatal and in special circumstances lethal complications, we need some more detailed information from good clinical trials and sufficient external quality assurance.

Abstract
Up to 15% of all fractures involve the clavicle. Nonunion of the clavicle is a rare complication after conservative treatment. It mainly presents as pain at the fracture site and a limited range of motion of the shoulder. The purpose of this study is to define a certain type of fracture of the clavicle that is predisposed to malunion and therefore should be treated surgically after failure of conservative treatment. Thirty-nine patients with delayed or malunion of the clavicle were analyzed. There were 13 women and 26 men. The average age of the male patients was 36.4 years (range 20-59 years) and of the female patients, 43.6 years (range 18-55 years). The mean follow-up period was 2.3 years (range 6 months to 4.2 years). All of them were treated surgically. There were 33 Allman I fractures and 6 Allman II fractures. Of the Allman I fractures, 30 (91%) were shortened by at least 2 cm. Allman I fractures were treated using a reconstruction plate or a dynamic compression plate in combination with bone grafting. The time of operation after fracture ranged from 6 weeks to 8.5 years (average 9.8 months). Pain at the fracture site was the leading symptom in all patients. At 6 months after the operation, 38 patients were free of pain with an unlimited range of motion of the shoulder. One patient (2.6%) complained of a slight weakness on the operated site. One fracture failed to unite (2.6%) and had to be replated. There were no refractures, infections, vessel or nerve lesions. To conclude, in Allman I fractures with a shortening of more than 2 cm, we recommend operative treatment in symptomatic patients if there are no signs of callus formation after 6 weeks.

Abstract
There is controversy over both the time of intervention and the technique of surgical stabilisation of femoral fractures in polytraumatized patients. Retrospective analysis of data on 55 such patients revealed that stabilisation within the first 24 h using locked, unreamed nails had no negative impact on the rate of pulmonary complications. The frequency of complications was assessed by comparing immediate intramedullary (IM) osteosynthesis with extramedullary stabilisation in patients with or without concomitant blunt thoracic trauma. Due to the small study population and discrepancies the size of subgroups, no definite statistical conclusions were possible. However, our results suggest that the frequency of complications is determined by the overall severity of injury rather than by the type of acute surgical treatment.

Abstract
Traumatic arterioportal fistulas (APF) are very rare. The most common reasons are liver biopsy and liver injuries. They are also caused by liver tumours and vessel anomalies. This is a case-report of a patient who developed an APF after blunt abdominal trauma. The fistula bearing part of the liver was resected in two sessions. In cases of large APFs with a flow from multiple collaterals the therapy of choice is the embolization. If not possible a selective excision of the fistulous sac or the resection of the fistula containing liver segment are recommended.

Abstract
INTRODUCTION It is generally accepted that septic conditions of the shoulder often lead to an earnest situation with joint damage. Because of the low incidence of shoulder infections there are only a few cases reported in the literature. Therefore, unlike joint infections of the knee no diagnostic and therapeutic standard procedure is documented for the shoulder. MATERIALS AND METHODS In a retrospective study the results of 15 patients with a surgical revision at the BG-Clinic-Bergmannsheil-Bochum between 1 January 1989 and 31 August 1999 after an infection of the shoulder joint were analyzed. We registered the following parameters: etiology, intervall until the first clinical symptoms, clinical signs, diagnostic procedure, intraoperative site (Gächter classification), and operative treatment. The diagnostic procedure followed an algorithm, including CRP-determination, ultrasound of the shoulder, ultrasound-guided aspiration and a Gram stain. If the result was positive, surgical joint revision followed. The infection stage was classified intraoperatively according to the criteria of the Gächter classification. Eight patients were reexamined after an average follow-up of 4.8 years. RESULTS Fourteen infections followed injection. All patients demonstrated increasing CRP levels and a painful limited range of motion. In all Gram stains we detected bacterial organisms. The diagnosis of an acute infection according to the criteria of this diagnostic algorithm was verified intraoperatively in all 15 joints. Two patients with delayed admission died postoperatively due to septic multiorgan failure despite maximal treatment under intensive care conditions. CONCLUSION If there are suspicious clinical symptoms after a typical anamnesis, we recommend an immediate diagnostic algorithm, including CRP determination, ultrasound of the shoulder, ultrasound-guided joint puncture and a Gram stain. If there is acute joint infection, time-consuming diagnostic procedures must be avoided because of the risk of secondary reduced joint mobility or life-threatening complications.

Abstract
Tracheostomy is a common surgical procedure performed in long-term ventilated patients in intensive care. Since the role of percutaneous dilatational tracheostomy (PDT) on Intensive Care Unit (ICU) has become steadily more important in the last few years, a prospective study was started to evaluate the economic efficiency and to show the minimization of the complication rate of this procedure. In 72 patients we performed PDT as a bedside procedure. Initially the thyroid gland and the subcutaneous vessels were studied by ultrasound in every patient. The puncture of the trachea, the dilatational procedure and the insertion of the tracheal cannula were executed under bronchoscopic monitoring. Finally, a bronchoscopic control view followed via the new cannula to detect intratracheal complications. Mechanical ventilation was maintained during the procedure and controlled by continuous pulse oximetry. According to prior ultrasound findings the place to puncture the trachea was changed in 24% of the patients, in one case tracheostomy was performed as an open conventional procedure. The following complications could be observed: one case involving perforation of a cartilaginous ring, one case with venous bleeding of a small subcutaneous vein and two cases with punctures of the bronchoscope. There were no cases of miscannulation, penetration of the posterior tracheal wall or major bleeding requiring intervention or conversion. The followup study revealed that there was no sign of further complications in any patient. In addition, cost analysis demonstrated that there was a significant economical advantage of PDT in comparison with open standard tracheostomy. Standardized ultrasonographically and bronchoscopically controlled PDT turns out to be a safe, simple and cost effective bedside procedure on ICU. Because of ultrasound examination performed before the procedure, and bronchoscopic surveillance during the procedure, safety of this procedure can be enhanced, thus minimizing the rate of complications.

Abstract
HYPOTHESIS A shift in the balance of helper T cells type 1 (T(H)1) toward type 2 (T(H)2) has been suggested as a possible mechanism for impaired immune responses after severe trauma. We suggest that major injuries (polytrauma) induce an alteration in the pattern of T(H)1/T(H)2 cells. DESIGN, SETTING, AND PATIENTS A prospective study of 35 polytraumatized patients (Injury Severity Score >16) admitted to a trauma intensive care unit at a level I trauma center (university hospital). INTERVENTIONS Blood samples were collected from patients at various times during their stay in the intensive care unit and from age- and sex-matched healthy individuals. MAIN OUTCOME MEASURES Serial determinations (n = 81) of intracellular interleukin (IL)-2 (T(H)1 cells) and IL-4 (T(H)2 cells) in stimulated CD3(+) T cells from patients with polytrauma twice a week during their stay in the intensive care unit accompanied by determination of the cell activation marker CD69 using 3-color flow cytometry. In parallel, the release of IL-2 and IL-4 from stimulated peripheral blood mononuclear cells and systemic plasma IL-4 levels were analyzed by conventional enzyme-linked immunosorbant assay. Healthy donors (n = 53) served as the control group. Data were related to outcome, Injury Severity Scores, and time after trauma. RESULTS Expression of the cell activation marker CD69 was similar in stimulated lymphocytes from patients and healthy donors. There were no significant posttraumatic alterations in numbers of CD3(+) cells stained for intracellular IL-2 or IL-4, except for a minor decrease in IL-2(+) cells during the first week after trauma. Subgroups with high (>24) and lower (<25) Injury Severity Scores or survivors and nonsurvivors revealed no differences in intracellular cytokine staining. In contrast, patients revealed a highly significant decrease in the number of CD3(+) T cells. Mean systemic IL-4 levels did not differ in patients compared with healthy donors. Release of IL-2 and IL-4 from peripheral blood mononuclear cell fractions stimulated with phorbolmyristateacetate and ionomycin was significantly increased in patients with trauma but not from those stimulated with toxic shock syndrome toxin-1. CONCLUSIONS Patients with multiple injuries have no significant alteration in the ratio of circulating T(H)1/T(H)2 cells. Thus, our results suggest pathomechanisms in posttraumatic T-cell suppression apart from alterations in the T(H)1/T(H)2 pattern.

Abstract
After detection of a bacterial infection of the joint, an absolute indication for intervention is given. Systemic antibiotic drug therapy is indicated and drainage of the joint has to be performed immediately. The following therapeutic algorithm regimen is a proven remedy in treating pyoarthrosis of the knee joint: During the initial period, the infection can be controlled by arthroscopic irrigation and systemic antibiotic therapy. Depending on the progredient findings or if the symptoms persist, curing the joint by open synovectomy is the next step of treatment. If open joint revision including synovectomy is not performed or is performed too late, there will be a threat of irreversible damage of the afflicted joint up to septic spread endangering the patient's life. We report on two patients suffering from generalized sepsis resulting in death after delayed therapy for knee joint infection. Regarding the presented cases, it can be concluded that indication to early surgical joint debridement including open synovectomy of the knee is still rarely seen after development of pyoarthritis.

Abstract
INTRODUCTION Interleukin-12-p70 (IL-12-p70) is a potent immunoregulatory cytokine composed of a heavy chain (p40) and a light chain (p35). Contradicting results have been reported with regard to leukocyte release and systemic concentration of IL-12 after polytrauma. METHODS We daily analyzed systemic concentrations of IL-12 in polytrauma patients (n = 37, mean ISS 33.9) in comparison to healthy donor values during intensive care course by ELISA. Patients were divided according to their mean IL-12 levels into those with elevated IL-12 (group 1, n = 7), those with decreased IL-12 (group 2, n = 4) and those with IL-12 in the normal range (group 3, n = 26). RESULTS Patients in group 1 revealed elevated levels of IL-12 up to p70 > 1000 pg/ml and p40 > 2500 pg/ml. The common clinical feature of group 1 was a thorax trauma in combination with pneumonia (85% survivors). Patients with single thorax trauma or pneumonia without thorax trauma (group 3) showed normal IL-12 values. Patients with decreased IL-12 levels revealed also a thorax trauma and pneumonia but all patients succumbed. The groups significantly differ in their stay in the intensive care unit, in TISS, in MODS score and in respiratory ratio, but not in ISS, mean CRP values and leukocyte counts. Correlation analysis revealed no significant relation between systemically altered IL-12 values and clinical parameters, with the exception of a negative correlation of p70 and ISS (r = -0.785) or MODS score (r = -0.314) in group 1. CONCLUSIONS After major injuries there is no overall suppression of IL-12 formation. Patients with normal or elevated IL-12 levels belong mainly to the survivors, whereas patients with decreased IL-12 levels are at high risk of succumbing to multi-organ failure.

Abstract
Fracture care in a geriatric population should lead to a mobilisation with full weight bearing as soon as possible after the accident. Osteoporosis and associated preexisting disease influences the kind of fracture care as well as the social situation. A retrospective analysis of 888 consecutive patients from 1994 to 1998 showed that the fracture risk for a second independent bony lesion was 5.2% in this population with a mean age of 83.4 years (75 y-97.2 y). 946 fractures were treated operatively with a overall reoperation rate of 10%. 3.1% were soft tissue revisions due to infection, 2.0% were because of implant failure in connection with a deep infection and 5.2% of the reoperation were indicated because of implant failure alone. Distribution of complications showed the advantage of closed, indirect reduction and intramedullary devices and primary hemiarthroplasty in femoral and humeral head fractures.

Abstract
Patients with severe trauma or polytrauma frequently acquire alterations in immune functions which are correlated to dysbalanced cytokine synthesis. In these settings the role of polymorphonuclear neutrophil granulocytes (PMN) as cytokine-producing cells is less well characterized. The immunosuppressive role of interleukin (IL)-10 is well known, and increased systemic IL-10 levels are related to the severity of injury and to posttraumatic complications. We determined concentrations of IL-10 in culture supernatants of 30 individual PMN fractions isolated from 18 severely traumatized patients (15 polytraumata, Injury Severity Score: 18-41, 3 severely burned patients) admitted to intensive care units. IL-10 was analyzed by ELISA (R&D Systems, Wiesbaden, Germany). PMN were isolated from EDTA-anticoagulated peripheral blood employing a one-step procedure based on a discontinuous double Ficoll gradient. The cells [1 x 10(6)/ml RPMI 1640 supplemented with 10% fetal calf serum and 25 mM N-(2-hydroxyethyl)-piperazine-N'-(2-ethanesulfonic acid] were stimulated with 0.05% heat-killed Staphylococcus aureus (Pansorbin, Calbiochem-Novabiochem, Bad Soden, Germany) for 24 h using cell culture conditions. Our results show that PMN fractions of traumatized patients produce significantly (P<0.008) higher amounts of IL-10 (354+/-95 pg/ml, n = 30) than normal healthy donor cells (125+/-95 pg/ml, n = 7). IL-10 release from PMN fractions exceeded the release from isolated patients' peripheral blood mononuclear cells induced by similar stimulation or by stimulation with toxic shock syndrome toxin-1 (10 ng) and concanavalin A (2 microg). Our results provide evidence that PMN fractions play an active role in the development of posttraumatic immunosuppression by autocrine or paracrine mechanisms, for example, by suppressing one's own antimicrobial activities or determining the development of T-cell responses via their ability to release IL-10.

Abstract
In this study of 154 patients with major abdominal cancer surgery, 41 postoperative complications occurred and caused additional total costs of DM 205.993,-, DM 5.024,- per case, respectively, where the special personnel costs were not accounted for. There was a significant difference between single and multiple complications as well as for early and late complication costs. Economic analyses are necessary to determine budgets of medical departments with extended and cost-intensive treatment, such as cancer surgery, to maintain optimal care for the patients.

Abstract
In this study mitoxantrone (Mtx) induced DNA strand breaks were measured with the alkaline elution technique in short term cell cultures derived from human gliomas. Glioblastomas or astrocytomas from 5 patients who underwent intracranial surgery were cultured and incubated i h with different concentrations of Mtx (0, 0.01, 0.1 and 1.0 microgram/ml). The alkaline elution method was modified to measure DNA lesions in human gliomas. Mtx induced DNA strand breaks in a dose dependent manner in all cell cultures tested. There was a linear increase of DNA strand break frequency induced by Mtx between 0.01-1.0 microgram/ml. concerning these in vitro data, Mtx might be potentially useful for the treatment of patients with malignant brain tumors.
