[Emergency room activation due to trauma mechanism]. / Schockraumindikation nach Unfallhergang.

BACKGROUND: The quality of trauma care in Germany has been significantly increased due to the establishment of standards in the white paper on severe injury care and the S3 guidelines. A key issue of multiple trauma treatment is the trauma resuscitation unit (TRU)/emergency room management, which is associated with extensive material and human resources. From the very beginning of the introduction of structured care for the severely injured, the choice of the target hospital and the indications for TRU have been the focus of scientific research. Furthermore, a reduction of the TRU team for presumably less seriously injured patients is discussed. MATERIAL AND METHODS: The emergency room assignments of a level I trauma center (n = 686) were analyzed in more detail. Of the patients 235 were assigned with the TRU indications according to the cause of the accident (GoR B criteria) and compared with the collective of TRU patients admitted according to the severity of injuries or life-threatening signs, the so-called GoR A criteria (n = 104) during the corresponding period. In addition to basic data (age, sex), the injured region and severity (injury severity score, ISS), the length of stay in the intensive care unit (ICU) and hospital as well as the necessity for surgery and transfusion were compared. RESULT: Of the emergency room allocations at the trauma center 34% were due to the cause of the accident and the severity of the injuries in this patient group was almost half as high as that of the control group with an ISS of 11. Of the patients 74% were admitted to the IMC/ICU and stayed there for an average of almost 3 days. There were between 4% and 18% severe injuries (abbreviated injury scale, AIS 3) and 17.9% were characterized as polytrauma with an ISS ≥ 16 points. CONCLUSION: A significant number of patients admitted to a TCU due to the cause of accident (the so-called B criteria of the white book), have severe and potentially life-threatening injuries, which necessitate a prioritized and immediate treatment by a TCU team. Whether a reduced TCU team is sufficient in this situation needs to be critically examined.

Diagnostics and early treatment in prehospital and emergency-room phase in suspicious pelvic ring fractures.

BACKGROUND: Testing for mechanical stability in pelvic ring fractures is advocated for the initial assessment and management of pelvic ring fractures. A survey among trauma surgeons showed that 91% agree with this recommendation. The aim of the present study was to describe the actual workup of patients with a high risk for unstable pelvic fractures in daily routine. METHODS: We performed a prospective multicenter observational study on patients admitted to the emergency room with suspected pelvic ring fractures. Data were collected anonymously via a standardized case report. RESULTS: A total of 254 patients with suspected pelvic injuries from 12 different trauma centers were included in this study. In 95 out of 254 cases a per definition unstable pelvic fracture could be confirmed; 46 type B and 49 type C fractures was confirmed. Mechanical stability examination was carried out in 61% and revealed a sensitivity of 31.6% and a specificity of 92.2%. 11.5% (18 patients) actually showed a mechanical instability (6 B# 12 C#). Regardless, 166 patients (65.4%) received noninvasive external stabilization ahead of diagnostic imaging, as a result of clinical judgment. 72% (24×) showed signs of significant bleeding in the subsequent CT scans. 33 pelvic ring fractures (type B or C) had no prehospital stabilization. CONCLUSION: Testing of mechanical stability of the pelvic ring was carried out less often and with lower consequences for the actual management than expected. It seems worthwhile to rather put on a pelvic binder at earliest occasion based on trauma mechanism or clinical findings to reduce the risk of serious pelvic bleeding.

[Primary radial head arthroplasty in trauma : Complications]. / Primäre posttraumatische Radiuskopfprothetik : Komplikationen.

Radial head fractures are common injuries in elbow trauma. Non-displaced fractures are best treated conservatively. Simple but displaced fractures require anatomic reduction and fixation, typically using screws. The treatment course for complex fractures with multiple fragments is still being debated, as results are less predictable. Radial head resection is not advised if concomitant injuries of the coronoid process or the collateral ligaments with instability are present. Favorable outcomes following open reduction and fixation using plates were reported recently. However, complication rates are very high. Radial head replacement is a valuable tool in treating complex fractures of the radial head with predominantly good and excellent results. Patients who suffer radial head fractures are typically of a younger age, resulting in high functional demands. Certainly, unspecific and specific complications related to radial head arthroplasty were reported in up to 40 % of cases in an acute fracture setting. This article highlights common complications in radial head arthroplasty and aims to present strategies to avoid them.

[Recommendations for Releasing the Pelvic Binder After a Non-Invasive Pelvic Stabilisation Procedure Under Emergency Room Conditions]. / "Clear-the-Pelvis-Algorithmus": Handlungsempfehlung zur Freigabe des Beckens nach nicht invasiver Stabilisierung mittels Beckengurt im Rahmen der Schockraumversorgung.

Severe brain, thoracic and intrapelvic injuries, as well as heavy bleeding, are the main causes of death in patients with major trauma. Unstable pelvic ring fractures can cause this bleeding and the so-called "C problem". This is usually due to haemorrhagic shock caused by the loss of large volumes of blood from the presacral venous plexus, iliac vessels and the fracture surfaces. Many clinical studies have shown that, in the preclinical setting, unstable pelvic ring injuries are often underestimated. The application of a non-invasive external pelvic ring stabilisation (pelvic binder) is therefore recommended if a pelvic fracture is possible. Several circumferential pelvic binders have been developed and their prehospital use is increasing. Clinical and biomechanical studies have demonstrated that there is a favourable haemodynamic effect in unstable fractures, due to rapid closure of the pelvic ring. It is unclear whether the pelvic binder can be safely removed in a presumably haemodynamically stable patient. A correctly placed pelvic binder leads to anatomical closure of the pelvic ring. Therefore unstable pelvic ring fractures may be clinically and radiologically overlooked. This is a particular problem in unconscious patients. Furthermore, the real severity of the injury may then be underestimated in the diagnostic evaluation. Unconsidered opening of the pelvic binder can thus provoke renewed deterioration of the circulatory situation, especially if the injury was adequately treated by the binder and the C problem was controlled. The aim of this article is to describe procedures for handling pelvic binders, particularly as to how to deal with an already applied pelvic binder and how to "clear the pelvic region" while reducing the risk of haemodynamic instability. A detailed analysis of the literature and a Delphi-like discussion among several experts were performed. The following points were raised: 1) Assessment of the clinical situation, including trauma kinematics. 2) Assessment of the haemodynamic status. 3) Check of the need to open the pelvic binder for diagnostic/therapeutic measures before completing all diagnostic tests. 4) Assessment of the radiology diagnostic testing and release of the pelvic region. The result is a so-called "clear the pelvis algorithm" which describes a structured approach according to specific criteria and which specifies the circumstances under which the pelvic binder can be opened. Additional studies are necessary to analyse the applicability and safety of this algorithm in a clinical context. Our advice is not to "clear" the pelvis if no X-rays or CT scans of the pelvis have been carried out without (or with an opened) pelvic binder.

[Practical courses for students can not only improve the teaching quality but can also increase the attractiveness of orthopaedic and trauma surgery]. / Praktische, berufsrelevante Kurse für Studierende können nicht nur die Lehre verbessern, sondern steigern auch die Attraktivität des Faches Orthopädie/Unfallchirurgie.

BACKGROUND: Students often complain about a lack of teaching of practical skills. This may be a cause for the low attractiveness of surgical disciplines. We therefore established a practical course to improve teaching quality to inspire the students for orthopedic and trauma surgery. METHODS: The platforms of the course included the teaching and acquisition of suture techniques, arthroscopy and osteosynthesis techniques. A total of 119 students participated in 9 courses and performed a detailed evaluation. RESULTS: The main motivation to participate was (i) to acquire practical skills (93 %), (ii) to learn about orthopaedic and trauma surgery (66 %) and (iii) to facilitate decision-making for the occupational choice (21 %). 94 % judged the quality of the course as "excellent", and all 119 participants indicated that they would recommend the course to other students. 43 of 45 students, who had not yet decided on their occupational choice, indicated that the course stimulated them for a career in orthopaedic and trauma surgery. CONCLUSION: This course not only can improve the teaching quality but also can increase the attractiveness of muskuloskeletal surgery.
