[Terror attacks : Recommendations for cooperation between police, hospitals and non-police security services]. / Lebensbedrohliche Einsatzlagen : Handlungsempfehlung zur Zusammenarbeit zwischen Polizei, Kliniken und nichtpolizeilicher Gefahrenabwehr.

BACKGROUND: The risk of terrorist attacks in the Federal Republic of Germany is present and is currently increasing. Publicly funded acute care hospitals and their owners are involved in disaster control as part of their remit and are responsible for taking comprehensive precautions to ensure their operational capability in the event of disasters. This mandate must also be ensured in the event of terrorist attacks and amok incidents. For this purpose, an optimal cooperation between preclinical and clinical care is indispensable. AIM: Recommended actions for collaboration between nonclinical and clinical planning to manage a mass casualty incident in terrorist life-threatening response situations are presented. MATERIAL AND METHODS: The Inter-Hospital Security Conference Baden-Württemberg (IHSC BW) is an association of representatives of acute hospitals in Baden-Württemberg, the Ministry of the Interior, Digitalization and Migration Baden-Württemberg, the Ministry of Social Affairs and Integration Baden-Württemberg, the State Police Headquarters Baden-Württemberg and the Baden-Württemberg Hospital Association. From 2018 to 2020, the IHSC BW developed recommendations for action on cooperation between police, hospitals and non-police emergency response. The recommendations for action were agreed by the group members in 6 working sessions and initialled in two subsequent video conferences. A recommendation was considered adopted when the IHSC BW plenary assembly finally gave its approval with an absolute majority. RESULTS AND DISCUSSION: Competence-based interface solutions for a smooth cooperation between prehospital and hospital management in the care of patients who have become victims of a terrorist attack are to be demanded. For preliminary planning, the establishment of a local safety conference at the county disaster control authority level with the following participants is recommended: disaster control authority, fire department, regional police headquarters, chief emergency physician, rescue services and disaster control officers of affected clinics. It is recommended to set up a joint command and situation center (CSC), where management personnel from the police, rescue service, fire department and disaster control can meet to organize the handling of the incident jointly, competently and without loss of time. From this CSC, a liaison officer should then provide the clinics with information at regular intervals. Exercises should take place regularly. Cross-organizational exercises are particularly important, and this is one of the tasks of the local safety conference.

Non-Union in Upper Limb Fractures - Clinical Evaluation and Treatment Options.

Although non-unions in the upper limb are rare different treatment options of this challenging situation are still affected with up to 20% of failure rate due to current literature. Risk factors for delayed and non-union of fractures are mainly the size of the fracture gap and bone loss of open fractures or in primary surgery followed by other relevant internal and external factors. In the upper limb non-unions of long bones are described with up to 30% after operative intervention. Especially in the upper limb range of motion is limited in non-union cases and disables adjacent joints like the shoulder, elbow and wrist hence reducing the total activity level of affected patients. Beside careful investigation of the causes leading to the non-union a comprehensive treatment plan should be defined to achieve successful results. Treatment can be non-operative in several, selected cases, but in the majority of cases revision surgery is necessary to achieve osseous healing. Our own experience showed that non-union in the upper limb are rare and account for only 1.7% of all surgical managed upper limb fractures. Non-union of upper limb fractures occur most frequently in clavicle fractures followed by humeral fractures. Atrophic non-union is the most frequent reason for osseous non-union (57%) and osseous healing after revision surgery in non-unions is completed after a mean of 6.45 months. This article will give a brief overview of the genesis, clinical evaluation, treatment options and recommendations in upper limb non-unions according to the current literature. Key words: fracture, upper-limb, non-union, osteosynthesis, cancellous bone-graft.

Comminuted Fracture of Elbow - Ostheosynthesis vs. Total Joint Replacement.

Comminuted fractures of the elbow are very rare and in most cases very complex and the successful treatment can be a challenge for the treating surgeon. Due to the elbow joint's complex functional anatomy, the multi-fragmentary nature of many fractures and concomitant destabilizing associated injuries, comminuted fractures of the elbow still present a serious challenge for the orthopedic surgeon. Especially in more severe communicated injuries an osteosynthesis or endoprosthesis must be discussed with the patient. There is a lack of clear treatment recommendations based on solid evidence. An overview of the literature including a treatment algorithm to guide decision making for the distal humeral fracture in the adults is presented and own results are analyzed. Key words: comminuted fracture of elbow, total joint replacement of the elbow, elbow prosthesis, elbow arthroplasty, distal humeral fracture.

[German trauma centers: level-dependent differences in polytrauma care regarding resources and diagnostic concepts]. / Polytraumaversorgung in Deutschland: Klinikabhängige Unterschiede in der Ressourcenvorhaltung und bei diagnostischen Konzepten.

BACKGROUND: The aim was to survey the radiological diagnostics and type of primary radiological examination of polytraumatized patients treated in German hospitals at various levels in the three-tiered system. MATERIAL AND METHODS: A questionnaire was sent in October 2007 to every traumatology department registered in the DGU (German Society for Trauma Surgery) databank and forms returned by January 2008 were included in this study. RESULTS: A total of 273 (54.71 %) of forms were returned and were applicable to statistical analysis. In the three-tiered hospital system 35.9 % of returned questionnaires came from third-tier hospitals, 41.02 % from second-tier and 23.08 % from highest tier (maximum care) hospitals. With a higher hospital level of inpatient care more computed tomography (CT) scans were examined by a radiologist during 24 h daily (p = 0.0014) and CT scanners were located closer to the resuscitation room (p < 0.0001). We found significant differences in the ratios of primary whole-body CTs (WBCT) performed depending on the hospital level: third-tier hospitals 44 %, second tier hospitals 67 % and maximum care hospitals 84 % (p < 0.05). CONCLUSIONS: Standardized structures regarding radiological diagnostics of polytraumatized patients do not exist at either the same level of the three-tiered hospital system or between levels of care of German hospitals..

A multicentre case series of tibia fractures treated with the Expert Tibia Nail (ETN).

INTRODUCTION: The aim of this study was to present clinical experience and outcomes of intramedullary nailing of proximal, midshaft and distal tibia fractures with the Expert Tibia Nail (ETN; Synthes GmbH, Switzerland), an implant offering a wide range of proximal and distal locking options in multiple planes to increase stability of the implant and bone construct. PATIENTS AND METHODS: 180 patients with 185 tibia fractures were enclosed between July 2004 and May 2005 from ten trauma units (Levels I, II and III) and treated with intramedullary reamed and unreamed nailing with the ETN. Patients attended examinations at 12 weeks and 1 year. The occurrence of postoperative complications was documented as well as the outcomes of fracture healing, primary and secondary malalignment, implant failure, rate of infection and the need for reoperation. RESULTS: The 1-year follow-up rate was 81 %. At 1 year, the prevalence of delayed union was 12.2 % and higher for open fractures (18.2 %) compared to closed fractures (9.7 %). According to the fracture location, the percentage of delayed union was 5.9, 16.7 and 10.5 % in proximal third, midshaft and distal third cases, respectively. Patients with a plated fibula fracture had an eightfold higher risk of delayed union. The rate of malalignment >5° in any plane 1 year after surgery was 5.5 %. Proximal third fractures were at a higher risk of postoperative malalignment (17.6 %). The rate of secondary malalignment was 1.4 %. The risk of unplanned reoperation was 9.2 %. CONCLUSION: Intramedullary ETN fixation of tibia fractures results in low rates of delayed union, primary and secondary malalignment, implant-related complications, and secondary surgery. Fibula plating had a negative effect on the healing of the tibia.

Tibial shaft fractures - management and treatment options. A review of the current literature.

Treatment of tibial shaft fractures is still discussed controversial. In the present study current literature was reviewed with the objective to demonstrate current recommendations concerning tibial shaft fractures. Tibial shaft fractures are often caused by high-energy trauma with severe concomitant soft-tissue injuries. Solid bone union without hypertrophy, fast mobilization and full range of motion without further soft-tissue damages are the aims of the therapy. Non-displaced tibial shaft fractures in patients with good compliance can be treated conservatively. Deep venous thrombosis, compartment syndrome, soft tissue injury and chronic regional pain syndrome are the major risks of conservative treatment and need to be required. Operative treatment can be performed with several different implants. Intramedullary nailing with a huge biomechanical stability seems to be the implant of choice. Only rare indications for plate osteosynthesis can be found. The use of external fixation has declined even though external fixation is still the implant of choice in first line treatment of multiple trauma according to the damage control principles. Open fractures with precarious blood supply and weak soft tissue covering are vulnerable to complications and remain a challenge for every treating surgeon. Reconstruction of axis, length and rotation is essential for a good outcome. The choice of technique depends on fracture localization, type of fracture, history of concomitant disorders and soft tissue damage.

[Radiological comparison between two procedures for ventral spondylodesis: autologous iliac crest bone graft vs bovine bone graft]. / Radiologischer Vergleich zweier Verfahren zur ventralen Spondylodese: Autologer trikortikaler Beckenkammspan vs. boviner Spongiosablock.

BACKGROUND: The objective of this study was the radiological evaluation of osseous integration of autologous iliac crest graft and bovine bone graft after spondylodesis based on a standardized score. MATERIAL AND METHODS: Spondylodesis was performed on 18 sheep, divided into 2 groups, 1 with an autologous iliac crest graft and the other with a bovine bone graft. Computed tomography was performed 12 and 24 weeks postoperatively. The osseous integration was assessed by the Tübinger Score. RESULTS: The evaluation of the CT scans demonstrated a significantly better osseous integration of the autologous iliac crest graft compared to the bovine bone graft. CONCLUSIONS: Based on our results, the bovine bone graft as a transplant for spondylodesis is inadvisable.

[Emergency room management of contaminated patients]. / Schockraummanagement beim kontaminierten Patienten.

Accidents with the risk of exposure to hazardous nuclear, biological, or chemical materials are rare. Most emergency rooms are not familiar with the management of contaminated patients after this kind of incident. There are also ambiguous cases concerning the contamination status of the patient. The medical attendance should be performed carefully and under special security arrangements until a hazard for third persons can be excluded. The security arrangements should protect both (medical) personnel and third persons. Early medical treatment combined with decontamination should be the aim. Based on the case of a contaminated patient who was brought to our emergency department after an explosion of a fog grenade with red phosphorus, we discuss our management concept and the current literature.

Effect of re-implanted particles from intramedullary reaming on mechanical properties and callus formation. A laboratory study.

This study investigated the quality and quantity of healing of a bone defect following intramedullary reaming undertaken by two fundamentally different systems; conventional, using non-irrigated, multiple passes; or suction/irrigation, using one pass. The result of a measured re-implantation of the product of reaming was examined in one additional group. We used 24 Swiss mountain sheep with a mean tibial medullary canal diameter between 8 mm and 9 mm. An 8 mm 'napkin ring' defect was created at the mid-diaphysis. The wound was either surgically closed or occluded. The medullary cavity was then reamed to 11 mm. The Reamer/Irrigator/Aspirator (RIA) System was used for the reaming procedure in groups A (RIA and autofilling) and B (RIA, collected reamings filled up), whereas reaming in group C (Synream and autofilling) was performed with the Synream System. The defect was allowed to auto-fill with reamings in groups A and C, but in group B, the defect was surgically filled with collected reamings. The tibia was then stabilised with a solid locking Unreamed Humerus Nail (UHN), 9.5 mm in diameter. The animals were killed after six weeks. After the implants were removed, measurements were taken to assess the stiffness, strength and callus formation at the site of the defect. There was no significant difference between healing after conventional reaming or suction/irrigation reaming. A significant improvement in the quality of the callus was demonstrated by surgically placing captured reamings into the defect using a graft harvesting system attached to the aspirator device. This was confirmed by biomechanical testing of stiffness and strength. This study suggests it could be beneficial to fill cortical defects with reaming particles in clinical practice, if feasible.

[Prehospital care of surgical emergencies]. / Präiklinische Erstversorgung chirurgischer Notfälle?

Surgical emergencies embrace the fields of general and visceral surgery (e.g. unclear/acute abdomen, blunt abdominal trauma, perianal venous thrombosis), vascular surgery (e.g.: venous and arterial bleeding, aortic aneurysm), accident, hand and plastic surgery (e.g. dislocations, fractures, amputation injuries, penetrating injuries, burns, hypothermia, complicated trauma, thoracic trauma). The prehospital treatment options discussed in the present article represent the current state of the art.
