RESUMO
BACKGROUND: In acute medical care, there are patients who have been injured by the influence of others. The aim of this study was to analyze all cases which were presented to the Institute for Legal Medicine of the University Halle (Saale). The cases where analyzed in relation to the victims' statistics of the state office of criminal investigation in Saxony-Anhalt. MATERIALS AND METHODS: The consultations of the Institute for Legal Medicine Halle-Wittenberg for 2012-2015 were evaluated with regard to the age and gender distribution, the reasons for the consultation and time until the request for consultations. These cases were statistically compared to the victims' statistics of the state office of criminal investigation in Saxony-Anhalt 2014-2015. RESULTS: A total of 536 cases (55.6% male and 44.4% female patients) were evaluated. In all, 62.1% of patients were under 18 years of age; 43.5% of all consultations were requested by pediatric (surgery) clinics. The most common reasons for consultation were sexual child abuse or violence against children (50.7%). Compared to the victims' statistics, significantly more children were examined by legal medicine specialists than could have been expected (p < 0.001). In adult patients, the most common causes for consultation were acts of violence (20.4%) and domestic violence (10.1%). Among adults, significantly more women and fewer men were presented than expected (p = 0.001). CONCLUSION: There were only a small number of consultations of legal medicine specialists in relation to the victims' statistics. Most of them were children and women. The temporal latency between the act of violence and the consultations was one day and more. The latency and the renunciation of the consultation of the legal medicine specialists can lead to loss of evidence.

Introduction: Surgical education of medical students within "skills labs" have not been standardised throughout Germany as yet; there is a substantial impact of available aspects such as personal and space at the various medical schools. Aim: The aim of this contribution is to illustrate the concept of a surgical skills lab in detail, including curricular teaching and integrated facultative courses at the Medical School, University of Magdeburg ("The Magdeburg Model") in the context of a new and reconstructed area for the skills lab at the Magdeburg's apprenticeship center for medical basic abilities (MAMBA). Method: We present an overview on the spectrum of curricular and facultative teaching activities within the surgical part of the skills lab. Student evaluation of this teaching concept is implemented using the programme "EvaSys" and evaluation forms adapted to the single courses. Results: By establishing MAMBA, the options for a practice-related surgical education have been substantially improved. Student evaluations of former courses presented within the skills lab and the chance of moving the skills lab into a more generous and reconstructed area led to a reorganisation of seminars and courses. New additional facultative courses held by student tutors have been introduced and have shown to be of great effect, in particular, because of their interdisciplinary character. Conclusion: Practice-related surgical education within a skills lab may have the potential to effectively prepare medical students for their professional life. In addition, it allows one to present and teach the most important basic skills in surgery, which need to be pursued by every student. An enthusiastic engagement of the Office for Student Affairs can be considered the crucial and indispensable link between clinical work and curricular as well as facultative teaching with regard to organisation and student evaluation. The practice-related teaching parts and contents at the surgical section of a skills lab should be integrated into the National Competence-based Catalogue of Teaching Aims in Medicine ("NKLM").

BACKGROUND: The initial diagnostic procedure of severely injured patients in the emergency room (ER) during the primary survey is first and foremost a clinical examination. The clinical S3 guidelines provide recommendations for the treatment of patients with severe and multiple injuries. OBJECTIVES: The study was performed to investigate the reliability of clinical key symptoms or red flags registered in the ER that lead to further diagnostic or therapeutic procedures. MATERIAL AND METHODS: An evaluation of key symptoms as a synopsis of the current literature considering aspects of probability calculation and medical experience was carried out. RESULTS: Key symptoms registered during the clinical examination are not sufficiently safe to be solely relied upon for further diagnostic and therapeutic decisions. This confirms the sense of purpose of the strict approach according to the advanced trauma life support (ATLS) algorithm. Red flags can serve as a warning to focus on relevant injuries early on. A rational imaging diagnostic procedure must follow.

Bisphosphonates (BP) play an important role in the therapy of osteoporosis as they effectively reduce the risk of fractures. Atypical femoral fractures (AFF) have recently been described as an adverse effect of BP treatment. We present 3 women under therapy with BP, who had five AFF, among these three complete and two incomplete fractures. The incidence of AFF under therapy with BP is low, and the benefit regarding reduction of spinal fractures and fractures of the proximal femur is much higher than the risk for an AFF.

AIM: The aim of this work is to illustrate the diversity of vascular injuries in terms of vascular segments or body regions, accident mechanisms and specific patient constellations. METHOD: A representative case collection was compiled based on current and relevant scientific references in PubMed, own clinical experiences, vascular surgical and novel image-guided interventional options. RESULTS: The diagnostics of vascular injuries in the context of trauma and fractures are based on a thorough physical examination. In addition, the hard and soft signs preferred by the Western Trauma Association should be included in the decision. Doppler ultrasonography examination is the safest and gentlest noninvasive examination procedure for a suspected vascular injury due to repeatable and comparative measurements. The stabilization of a fracture, ideally using an external fixator, should be performed before vascular reconstruction whenever possible, unless massive bleeding, hypovolemic shock or a rapidly spreading hematoma represent an immediate indication for surgery. In pediatric supracondylar fractures, avascular injury without relevant ischemia has frequently been described (pink pulseless hand). In this case, the fracture should first be reduced as the pulse often recovers. Due to the increasing availability, good technical handling and high technical success rate as well as the relatively limited interventional trauma, endovascular treatment of traumatic vascular injuries has become widely accepted. Traumatic aortic ruptures are associated with a high mortality even at the accident site. Rapid endovascular treatment using a stent prosthesis significantly increases the injured person's chances of survival. CONCLUSION: Vascular injuries in connection with fractures or multiple injuries require interdisciplinary cooperation between the specialties involved.
RESUMO
BACKGROUND: Osteopenia (OP) or osteoporosis (OST) was diagnosed by bone densitometry (DXA) in postmenopausal women free of known skeletal disorders and without acute fracture. DVO guidelines were applied to define therapeutic indication. METHODS: The study included 94 women aged 59-81 years. Fracture or operation ≤12 months, malignant tumor, ovariectomy, and drugs such as cortisone, strontium, fluorides, bisphosphonates, SERMs, estrogens, and steroids were exclusion criteria. The lowest T-score at the spine, femoral neck, or total hip was decisive. The indication for therapy was determined by evaluating age, BMD, and other risk factors. RESULTS: Using the WHO criteria 22.3% (n=21) had normal BMD, 52.1% (n=49) had OP, and 25.6% (n=24) had OST. According to "Dachverband Osteologie" (DVO) guidelines, 28 women (29.8%) of the whole group needed therapy. Of the 28 women receiving therapy, 9 had OP and 19 had OST. Therapy was indicated in 18.4% for OP and 79.2% for OST. CONCLUSION: A preventive measurement of BMD with DXA provides a benefit for postmenopausal women. Combinatory assessment and consideration of other risk factors allows identification of women who might benefit from early treatment.

Biomechanical limits based on pain thresholds ensure safety in workplaces where humans and cobots (collaborative robots) work together. Standardization bodies' decision to rely on pain thresholds stems from the assumption that such limits inherently protect humans from injury. This assumption has never been verified, though. This article reports on a study with 22 human subjects in which we studied injury onset in four locations of the hand-arm system using an impact pendulum. During the tests, the impact intensity was slowly increased over several weeks until a blunt injury, i.e., bruising or swelling, appeared in the body locations under load. A statistical model, which calculates injury limits for a given percentile, was developed based on the data. A comparison of our injury limits for the 25th percentile with existing pain limits confirms that pain limits provide suitable protection against impact injuries, albeit not for all body locations.

BACKGROUND: With regard to the treatment of non-reconstructable radial head fractures, both the resection and the implantation of a prosthesis are considered. Various studies have shown poor results concerning the resection of the radial head with accompanying osteoligamentous injuries. Due to these experiences, different types of prosthesis have been developed. However, the majority of them were not convincing. Judet developed a type of a bipolar prosthesis which had been modeled on the anatomy of the radial head. The aim of our retrospective study consists in examining the results of the Judet prosthesis. PATIENTS AND METHODS: Between 1995 and 2007, 50 patients were treated with an arthroplasty. These were, corresponding to the classification by McKee and Jupiter, 19 type III and 31 type IV fractures. Thirty patients were available for a follow-up after 2.5 years on average. RESULTS: According to the Morrey Score, 16 very good, 7 good, 3 fair and 4 bad results could be obtained. Following the criteria of Radin and Riseborough, 17 patients achieved a good, 9 a fair and 4 a bad result. The complications which appeared were: one patient with aseptic loosening, one patient with luxation of a prosthesis, one persistent radial joint instability, three patients with heterotopic ossification and four patients with protrusion relative to the capitulum humeri.

BACKGROUND: The treatment of pediatric femoral shaft fractures has undergone an increasing change in recent years. The previously predominant treatment procedures were extensively replaced by minimally invasive techniques (e.g. elastic stable intramedullary nailing, ESIN). The aim of this study was the comparison of complication rates depending on patient factors as well as various treatment procedures. MATERIAL AND METHODS: This study involved a retrospective Xray morphometric evaluation of data. The patient files and Xrays of 101 children who were treated at 2 level I trauma centers were analyzed. RESULTS: Conservative treatment was carried out in 19% of the cases. Among the surgical procedures the ESIN technique was predominant (nâ¯= 60). Complications that needed revision occurred in 10% of the children after conservative treatment. Revision surgery had to be carried out in more than 6% of the cases in children who were surgically treated. Among the surgical procedures ESIN stabilization demonstrated the lowest revision rate with only 3%. Children under three years and adolescents had a higher risk for developing complications. If the ESIN wires used were too thin in relation to the diameter of the medullary cavity there was an increased probability of complications of around 30%. CONCLUSION: This study revealed a moderate risk of complications in the treatment of femoral shaft fractures in children. The risk of complications after external fixation and conservative treatment was the highest in this study. Overall, the ESIN technique showed the lowest risk of complications. The results of this study could confirm the known limitations of the ESIN technique depending on age and body weight.

BACKGROUND: There are well-defined criteria for the treatment of distal radius fractures but the impact of an unrepaired fracture of the styloid process of the ulnar on recovery after operative treatment is uncertain. This study evaluated radiological and functional results after different operative treatment procedures of distal radius fractures in patients with an untreated fracture of the styloid process of the ulna and those without such a fracture. METHODS: Out of 480 patients with operatively treated distal radius fractures 238 were examined at least 1 year after injury. The fracture of the styloid process of the ulna was not repaired. Three groups (patients without a fracture of the styloid process of the ulna, patients with a tip fracture and those with a basal fracture) were evaluated by multivariate analysis (MANOVA) in order to detect influences of the fracture of the styloid process of the ulna on the radiological and functional results. RESULTS: Neither the existence nor the location of the fracture of the styloid process of the ulna had a significant effect on the radiological and functional results (p(function)=0,849, p(radiology)=0,330, p(scores)=0,426, MANOVA). CONCLUSIONS: The repair of a fracture of the styloid process of the ulna is not necessary if reduction and fixation of the distal radius fracture is anatomical and stable.

Collaborative robots (cobots) provide a wide range of opportunities to improve the ergonomics and efficiency of manual work stations. ISO/TS 15066 defines power and force limiting (PFL) as one of four safeguarding modes for these robots. PFL specifies biomechanical limits for hazardous impacts and pinching contacts that a cobot must not exceed to protect humans from serious injuries. Most of the limits in ISO/TS 15066 are preliminary, since they are based on unverified data from a literature survey. This article presents a human-subject study that provides new and experimentally verified limits for biomechanically safe interactions between humans and cobots. The new limits are specifically tailored to impact and pinching transferred through blunt and semi-sharp surfaces as they can occur in the event of human error or technical failures. Altogether 112 subjects participated in the study and were subjected to tests with emulated impact and pinching loads at 28 different body locations. During the experiments, the contact force was gradually increased until the load evoked a slightly painful feeling on the subject's body location under test. The results confirm that the pain thresholds of males and females are different in specific body regions. Therefore, when defining biomechanical limits, the gender difference must be taken into account. A regression model was utilized to incorporate the gender effect as a covariate into a conventional statistical distribution model that can be used to calculate individual limits, precisely fitted to a specific percentile of a mixed group of male and female workers which interacting with cobots.
RESUMO
OBJECTIVES: The aim of the study was to analyze helicopter emergency medical service (HEMS) in comparison to EMS, in respect to patient's mortality and morbidity. DESIGN: From a cohort of traumatized patients (n = 1724) prospectively enrolled in the German trauma registry (DGU-R) at Frankfurt University Hospital from 2009 to 2013, 1646 could be analyzed for in-hospital mortality and short-term outcome (GOS) at discharge and compared between HEMS and EMS. MEASUREMENTS AND MAIN RESULTS: 129 patients (7.8%) died in the hospital. Unadjusted mortality was significantly lower in the HEMS group compared to EMS (p = 0.001). In a multiple logistic regression analysis after adjustment of variables including reanimation and age as the strongest predictors, in-hospital mortality was significantly reduced in HEMS (p = 0.014, OR = 0.21). Further predictors in the multiple logistic regression analysis were GCS > = 8 (p = 0.001), RRsys (p < 0.001), ISS at Head/Neck > = 3 (p = 0.003), and total ISS > = 9 (p < 0.001). Total rescue time and on scene time were associated with mortality (p < 0.001) but not included in the multiple logistic regression model. Without adjustment, short-term outcome (GOS) was significantly improved (p = 0.014). In a linear model, after adjusting for multiple variables including age, ISS Head/Neck > = 3, ISS Extremities > = 3, GCS > = 8, and RRsys as the strongest predictors (p < 0.001), the association remained significant (p = 0.043). Further predictors in the multiple linear regression analysis were total ISS > = 9 (p = 0.002), ISS abdomen (p = 0.001), and ISS Chest (p = 0.011). CONCLUSIONS: A significant improvement for in-hospital survival for HEMS could be demonstrated. Especially in Germany, with a high number of secondary call outs (about 44%) after EMS has already reached the traumatized patient, HEMS must be the first choice for severely injured trauma patients. Dispatch criteria for immediate alarm of HEMS are recommended under practical considerations.

The scaphocapitate fracture syndrome as a greater arc injury is a special form of the perilunate fracture dislocation. It is a combination of fractures of the scaphoid and capitate bones. This severe injury of the carpus is rare and therefore difficult to diagnose. We report the case of a 22-year-old handball player, who fell on the outstretched hand with the wrist in extension. Open reduction was performed via a dorsal approach and both fractures were treated operatively with Herbert screws. After three months the patient was able to play handball again with a good functional result.

BACKGROUND: Heterotopic ossification is a complication in patients with surgically treated acetabular fractures. The incidence is related to the surgical approach (extended iliofemoral, posterior or a combined approach). The objective of this study was to evaluate the incidence of heterotopic ossification in patients with acetabular fractures who received a combined prophylaxis with both a single dose of radiation and indomethacin compared to those who received only a prophylaxis with radiation or indomethacin. PATIENTS AND METHODS: A total of 24 patients with a combined prophylaxis after surgery were examined retrospectively 24 months after trauma. A systematic literature review was performed and our own results were compared with different methods for prophylaxis of heterotopic ossification from the literature. RESULTS: Only one patient developed a heterotopic ossification. In accordance with the literature, combined prophylaxis showed the least incidence of ossification compared to the other methods. Differences in incidence frequencies were significant between the different prophylaxis methods. CONCLUSION: A combined prophylaxis for heterotopic ossification in surgically treated acetabular fractures seems to be a better alternative than a prophylaxis with radiation or indomethacin alone.

Fractures in the midline of the sacrum are rare, a pseudarthrosis has not been described previously. We report about a 53-year-old woman with a midline fracture of the sacrum which has not been recognized, although there were indirect fracture signs on the native x-rays and a CT was performed. The surgical treatment with sacral compression bars was successful and pseudarthrosis healing resulted but the patient continued to have mild low back pain. The case reported here confirms that low back pain may caused by pathologic changes of the posterior part of the pelvis. The unusual fracture location could be caused by a bifid spinous process.

PURPOSE OF THE STUDY: Antegrade intramedullary nailing is seen as a most effective method in the management of femoral fractures. However, complications may arise due to the surgical approach.Can these disadvantages be avoided by using a retrograde approach? MATERIAL AND METHODS: In a prospective study 70 femoral fractures in 62 patients were stabilised using a long intramedullary nail by a retrograde approach. RESULTS: We were able to re-examine 50 patients (57 fractures) 13,3 (3-36) months after the operation. Apart from one non-union by infection, all fractures healed in time. Flexion of the knee joint was within a normal ROM in 81% of shaft fractures 12 months or more after the operation, as was the case in 44% of distal fractures. A inhibition of extension was not found in any patient. Two patients had a femoral shortening of up to one centimeter. We observed no rotational malalignment of more than 5 degrees. The clinical results were excellent in 89% of shaft fractures, and in 50% of supra-/diacondylar fractures. In 18 cases a nail removal was already performed, thereby allowing an arthroscopic follow-up inspection of the knee joint. No knee pathology due to nailing was found in either case. CONCLUSION: Our results show the advantages of retrograde intramedullary nailing in comparison to the antegrade method.

PURPOSE OF THE STUDY: Comminuted fractures of the radial head represent a particular therapeutic problem. Due to characteristic complications the resection as well as the implantation of the Swanson-prothesis could not convince. MATERIAL AND METHODS: We applied the radial head prothesis of Judet in 16 cases (14 type IV and 4 type III by Mason). RESULTS: At the moment we survey the follow up of 15 patients after 12 to 45 months (average 18.2), the evaluation was performed using the score of Radin and Riseborough and the score of Morrey. With the score of Radin and Riseborough we found in 7 cases good, in 6 case fair and in 2 case poor results. With the score of Morrey we found 2 excellent, 11 good and 1 fair and poor results. The radiological examination did not show an increase of the carrying angle of the elbow, an osteoporosis, a proximal migration of the radius and a distal radio-ulnar dissociation. CONCLUSION: Compared with resection or Swanson-prothesis the bipolar prothesis of Judet has definite advantages.

We analyzed reasons, numbers and results of arterial lesions accompanying fractures (n = 21) and luxations (n = 6) in a 6-year-period (1993-1998) retrospectively. Traffic accidents were in nearly 50% responsible for the injuries. 8 patients had suffered multiple injuries. In 17 patients the lower, and in 10 patients the upper extremities were affected. The vascular wall was completely disrupted or severed in 74%. In 7 cases (26%), patients had suffered blunt or indirect arterial trauma with intima- and media-lacerations due to subcapital fracture of the humerus (n = 2), fractured femoral bone (n = 1), luxation of the knee joint (n = 3) or the elbow (n = 1). The mean preoperative time period was 6 hours and 20 minutes (2 to 16 hours) in patients with complete ischaemia. Vascular reconstruction was performed by interposition of an autologous vein graft or an autologous venous bypass (n = 20), by direct reconstruction and primary suturing (n = 2), by use of a venous patch plasty (n = 2) and, in a single case, by autologous bypass procedure. In one case, a crural artery was ligated, in another case with a Mangled Extremity Severity Score (MESS) of 7 points a primary amputation of the lower leg was necessary. In 5 patients (19%) secondary amputations were performed. No patient died. The final outcome is mostly influenced by the preoperative period of ischaemia.

Laparoscopic transperitoneal and endoscopic extraperitoneal adrenalectomy are two safe options in minimally invasive surgery associated with a very low morbidity. Comparative studies with the conventional access to the adrenal gland demonstrated the advantages of the endoscopic technique. The anterior transperitoneal approach yields a better exposure of the anatomic structures and allows the surgeon to orient himself more easily, while at the same time he may perform additional laparoscopic maneuvers. In two cases of bilateral pheochromocytoma a bilateral laparoscopic adrenalectomy was performed simultaneously by employing the transperitoneal approach. The duration of surgery was approximately 210 and 270 min, respectively, with an intraoperative blood loss of about 350 and 400 ml. There were no complications following this procedure. Already on the 1st postoperative day, the patients could be fully mobilized. Furthermore, immunological data obtained perioperatively support the minimal invasiveness of this technique.
