RESUMO
The reconstruction of large osteochondral defects is still a challenge in musculoskeletal surgery. Fresh frozen allografts are a frequently used resource for the treatment of such tissue defects. Furthermore, 3D-printed models enable multiple options in the preoperative planning and intraoperative adaptation of the allografts, so that healing is optimal and the best functional outcome for the patient is achieved.

This article presents the case of an 83-year-old woman with a peri-implant femoral fracture after hip arthrodesis in adolescence. Due to the rarity of such operations, there is no standardized approach for these cases. In order to secure the treatment goal of rapid pain-adapted full weight bearing despite reduced bone quality, it was decided to perform a new osteosynthesis with a retrograde femoral nail after removal of some fixation screws of the existing arthrodesis plate. Due to this type of treatment, the preservation of activity and independence of an older trauma patient could be sustainably secured despite operative challenges. Taking an extended osteoporosis treatment into consideration, a bony fracture consolidation and complete convalescence of activity and autonomy were ultimately achieved.

The upper limb is one of the most frequently injured body regions in equestrian sports, but it is unclear which injuries are involved, and there are no data on the associated accident mechanism. The present study is aimed at evaluating the accident mechanisms, injuries of the upper limbs, and the circumstances of the accident in equestrian sports. We included 218 patients who were all treated between 2006 and 2014 at the level I trauma center at the Medical University in Hannover because of equestrian-related accidents. The most frequent injuries were fractures and bruising in the shoulder area, fingers and hands, and the distal area of the lower arm, which were mostly caused by the horse kicking. To prevent hand injuries it is recommended that gloves are worn; the potential introduction of strengthened materials could protect the bones from severe bumping. Training in falling techniques to prevent serious injury to the upper limb would be useful. In general, primary prevention in equestrian sports should be extended to counteract the increasing neglect of protective equipment.

BACKGROUND: Equestrian sports are one of the most popular forms of sport in Germany, while also being one of the most accident-prone sports. Furthermore, riding accidents are frequently associated with a high degree of severity of injuries and mortality. Nevertheless, there are insufficient data regarding incidences, demographics, mechanisms of accidents, injury severity and patterns and outcome of injured persons in amateur equestrian sports. Accordingly, it was the aim of the present study to retrospectively analyze these aspects. METHODS: A total of 503 patients were treated in the emergency room of the Hannover Medical School because of an accident during recreational horse riding between 2006 and 2011. The female gender was predominantly affected with 89.5 %. The mean age of the patients was 26.2 ± 14.9 years and women (24.5 ± 12.5 years) were on average younger than men (40.2 ± 23.9 years). A special risk group was girls and young women aged between 10 and 39 years. The overall injury severity was measured using the injury severity score (ISS). RESULTS: Based on the total population, head injuries were the most common location of injuries with 17.3 % followed by injuries to the upper extremities with 15.2 % and the thoracic and lumbar spine with 10.9 %. The three most common injury locations after falling from a horse were the head (17.5 %), the upper extremities (17.4 %), the thoracic and lumbar spine (12.9 %). The most frequent injuries while handling horses were foot injuries (17.2 %), followed by head (16.6 %) and mid-facial injuries (15.0 %). With respect to the mechanism of injury accidents while riding were predominant (74 %), while accidents when handling horses accounted for only 26 %. The median ISS was 9.8 points. The proportion of multiple trauma patients (ISS > 16) was 18.1 %. Based on the total sample, the average in-hospital patient stay was 5.3 ± 5.4 days with a significantly higher proportion of hospitalized patients in the group of riding accidents. Fatal cases were not found in this study but the danger of riding is not to be underestimated. The large number of sometimes severe injuries with ISS values up to 62 points can be interpreted as an indication that recreational riding can easily result in life-threatening situations. CONCLUSION: Girls and young women could be identified as a group at particular risk. It has been demonstrated in this study that the three most common injury locations after falling from a horse were the head, the upper extremities, the thoracic and lumbar spine. The most frequent injury locations while handling horses were foot injuries, followed by head and mid-facial injuries.

The cervical spine is considered fragile and vulnerable to injuries in equestrian sport. This retrospective study investigates the injury pattern and severity. Patients of the medical university in Hannover from the years 2006-2011, who had an equestrian accident, were identified. Patients who had been injured in the course of their work were excluded. Results counted with a p-value < 0.05 were considered significant. In 13.1% of patients, there were 71 cervical spine injuries (92.4% female; 7.6% male). The mean age was 27.1 ± 13.2 years. Of these, 86.4% associated the injury to the riding accident. In 56 cases, it concerned falls from the horse. In 13.6% of the cases, the injury was caused while handling the horse. Sprains were most common (70.4%). Fractures of the neck vertebrae were found in 22.5% of the cases. The mean ISS was 7.0 ± 5.8 pts. Polytrauma was identified in 6.1% of patients (ISS ≥ 16 Pkt). The most common accompanying injury presented was an injury to the head (29.2%; p = 0.003). Of the 30 hospitalized patients, 13.3% were admitted to intensive medical care for 2.3 ± 15.4 d. The mortality was 0%. Injuries of the cervical spine are not to be underestimated in their frequency and severity. It is shown that, especially with injuries of the head and thoracic and lumbar spine area, patients are at increased risk of concurrent cervical lesions. The prevention of neck injuries is currently done in the form of riding helmets, airbag jackets, riding behavior and education. Further study of the prevention of neck injuries is required.

OBJECTIVE: Negative pressure wound therapy (NPWT) has become an established treatment of traumatic and infected wounds. Negative pressure wound therapy with instillation (NPWTi) is a further development that combines the conventional NPWT with instillation of different fluids which continuously administer therapeutic reagents to the wound. The aim of this study was to compare the impact of additional saline instillation in NPWTi to NPWT alone. METHOD: Between January and July 2014, consecutive patients with acute wounds of the lower limb were treated with NPWTi with saline instillation. The number of revision surgeries, length of hospital stay, and duration of treatment until final healing were recorded and compared with matched patients undergoing NPWT without instillation. RESULTS: There were 10 patients recruited with 10 matched controls examined restrospectivley. Patients who received NPWTi were found to have decreased time of hospitalisation (21.5 versus 26.5 days, p=0.43), and accelerated wound healing (9.0 versus 12.5 days, p=0.36) than patients who received NPWT. However, the difference in the outcomes of the patients who received NPWTi and patients who received NPWT was not found to be statisticallly significant. CONCLUSION: NPWTi with instillation of saline is a promising method and its effectiveness needs to be tested in a randomised controlled trial compared with NPWT alone. DECLARATION OF INTEREST: This study obtained support by KCI (Wiebsaden, Germany) for the surgical material.

Abdominal seat belt marks can be an indication of abdominal wall rupture. The focused assessment with sonography for trauma (FAST) and computed tomography (CT) scanning are the diagnostic tools of choice in hemodynamically stable patients. The typical mechanism of trauma frequently leads to additional intra-abdominal injuries, spinal injuries and in some cases aortic rupture. Abdominal wall injuries of grade IV according to Dennis should be surgically treated. The increasing numbers of obese vehicle occupants and the resulting special risk of injury warrant optimization of technical restraint systems.

Splenic immune function is known to be depressed following hemorrhage. The present study investigates the effects of femoral shaft fracture, isolated or in combination with hemorrhage, on early stage cytokine production capacity of splenocytes and observes the role of IL-6 under these conditions. Male IL-6 knockout (IL-6(-/-)) and wild-type mice (WT) were randomly divided into three groups: sham (S), isolated femoral fracture (Fx), and femoral fracture + volume controlled hemorrhage (TH-Fx) (n = 6 per group). Animals were sacrificed four hours after induction of hemorrhage and fracture. Cytokine release (TNF-α, IL-6, and IL-10) of isolated and LPS-stimulated splenocytes was determined by cytometric bead array. Femoral fracture with or without hemorrhage caused a suppression of in vitro cytokine production capacity of splenocytes at an early posttraumatic stage in WT and IL-6(-/-). In the absence of IL-6, the profile of splenic cytokine secretion is significantly altered, identifying this cytokine as a potential therapeutic target to modulate the posttraumatic immune response.

OBJECTIVE: Despite broad research in neurotrauma and shock, little is known on systemic inflammatory effects of the clinically most relevant combined polytrauma. Experimental investigation in an animal model may provide relevant insight for therapeutic strategies. We describe the effects of a combined injury with respect to lymphocyte population and cytokine activation. METHODS: 45 male C57BL/6J mice (mean weight 27 g) were anesthetized with ketamine/xylazine. Animals were subjected to a weight drop closed traumatic brain injury (WD-TBI), a femoral fracture and hemorrhagic shock (FX-SH). Animals were subdivided into WD-TBI, FX-SH and combined trauma (CO-TX) groups. Subjects were sacrificed at 96 h. Blood was analysed for cytokines and by flow cytometry for lymphocyte populations. RESULTS: Mortality was 8%, 13% and 47% for FX-SH, WD-TBI and CO-TX groups (P < 0.05). TNFα (11/13/139 for FX-SH/WD-TBI/CO-TX; P < 0.05), CCL2 (78/96/227; P < 0.05) and IL-6 (16/48/281; P = 0.05) showed significant increases in the CO-TX group. Lymphocyte populations results for FX-SH, WD-TBI and CO-TX were: CD-4 (31/21/22; P = n.s.), CD-8 (7/28/34, P < 0.05), CD-4-CD-8 (11/12/18; P = n.s.), CD-56 (36/7/8; P < 0.05). CONCLUSION: This study shows that a combination of closed TBI and femur-fracture/ shock results in an increase of the humoral inflammation. More attention to combined injury models in inflammation research is indicated.

BACKGROUND: Cases with subcutaneous metastasis of differentiated hepatocellular carcinoma to the abdominal wall without prior seeding as a consequence of local interventions with a negative or normal alpha-fetoprotein level in the serum are extremely rare. CASE REPORT: This is the first report of a case with AFP-negative, differentiated hepatocellular carcinoma metastasis to the abdominal wall within a pre-existing subcutaneous lipoma since childhood after antiandrogen therapy with leuprorelin and buserelin acetate for prostate cancer without seeding. METHODS: Clinical features including histology, immunohistochemistry, clinical course and surgical approach are presented. RESULTS: Histological examination revealed a hepatocellular carcinoma with a trabecular and pseudoglandular growth pattern with moderately atypical hepatocytes with multifocal bile formation within a lipoma. The postoperative course of abdominal wall reconstruction with a monocryl-prolene mesh and a local flap after potentially curative resection was uncomplicated. DISCUSSION AND CONCLUSION: It may be that previous antiandrogen treatment for prostate carcinoma contributed to the fact that our patient developed alpha-fetoprotein-negative and androgen receptor-negative subcutaneous abdominal wall metastasis within a pre-existing lipoma since childhood.

BACKGROUND: Hypothermia, defined as a body core temperature below 35 °C, could be divided into an endogeneous, therapeutic and accidental hypothermia. At admission in the emergency room multiple trauma patients show a hypothermic core temperature in up to 66 %. A core temperature below 34 °C seems to be critical in these patients as this temperature limit has been demonstrated to be associated with an increased risk for post-traumatic complications and a decreased survival. In polytraumatised patients with a core temperature below 32 °C a mortality rate of 100 % has been described. MATERIAL AND METHODS: The main pathophysiological effects of hypothermia concern the haemo-dynamic, coagulatory and immune systems. Mild hypothermia (35-32 °C) leads to a vasoconstriction, tachycardia and increased cardiac output. After an increasing arrhythmia and bradycardia severe hypothermia (< 32 °C) finally results in a cardiac arrest. Hypothermia-induced coagulopathy comprises a dysfunction of the cellular and plasmatic coagulation with an increased blood loss. Due to the attenuation of the post-traumatic, pro-inflammatory immune response and enhancement of anti-inflammatory reactions, hypothermia counteracts an overwhelming systemic inflammation, concomitantly resulting in an increased susceptibility for infectious complications. RESULTS: Because of the negative effects of the -accidental hypothermia, effective rewarming is essential for adequate bleeding control and successful resuscitation. As aggressive rewarming (> 0.5 °C / h) has been reported to be associated with an increased mortality during the further course, this procedure should only be applied in hypothermic multiple trauma patients with haemorrhagic shock. CONCLUSION: Accidental hypothermia represents a serious problem in multiple trauma patients due to its frequency and negative pathophysiological effects. Therefore, early and effective re-warm-ing is essential in the treatment of hypothermic trauma patients. Possible protective effects of a therapeutic hypothermia in the treatment of trauma patients after initial resuscitation and operative bleeding control have to be clarified in further experimental and clinical studies.

Alveolar macrophages (AM) play an important role in the pathogenesis of posttraumatic pulmonary failure, and have been identified as major source of pulmonary cytokines. The effects of locally generated IL-6 as well as femoral fracture on the pulmonary inflammatory response and organ damage have not been fully elucidated. In the present study we evaluated the influence of femoral fracture, isolated or in combination with hemorrhage, on the immune function of AM and remote lung injury, and investigated the role of pulmonary IL-6 within this setting. 18 wild type (WT) and 18 IL-6 knockout mice (IL-6(-/-)) underwent standardized femoral fracture, isolated or in combination with volume-controlled hemorrhage, followed by fluid resuscitation and splint fixation of the fracture. Animals were sacrificed 4h after induction of fracture and hemorrhage. Animals were randomly assigned to three study groups (each consisting of six animals). Besides sham groups, experimental groups included animals with isolated femoral fracture or in combination with hemorrhagic shock. Cytokine release of AM was determined by flow cytometry. Pulmonary damage in terms of interstitial thickening and lung neutrophil infiltration was assessed by histology and immunohistology. The productive capacity of AM for pro-inflammatory cytokines was increased after isolated femoral fracture in WT and IL-6(-/-) mice. An additional hemorrhagic insult resulted in a further enhancement of pro-inflammatory cytokine release and an increased MCP-1 secretion in WT and IL-6(-/-) animals. MCP-1 and pro-inflammatory cytokine production of AM was attenuated in IL-6(-/-) mice compared to the respective WT groups. Interstitial thickening and lung neutrophil infiltration was only observed after femoral fracture combined with hemorrhagic shock with an attenuation of the pulmonary organ damage in IL-6(-/-) compared to WT animals. These results support the role of IL-6 as a therapeutic target for posttraumatic immune modulation. With an increased pro-inflammatory mediator release, already an isolated femoral fracture seems to influence the immune response of AM.

Due to the development of trauma care systems the treatment results of multiply injured patients have clearly improved during the last decades. More sophisticated preclinical algorithms, standardized procedures in the emergency room, calculated surgical strategies during the early phases and the subsequent intensive care (ICU) treatment as well as the implementation of trauma registries have all contributed to an improvement in trauma care. Different national trauma care systems have been developed due to the structural, geographic and demographic differences of the compared countries. However, large financial resources are required to maintain all three trauma care systems. To cope with financial losses in multiple trauma care, huge efforts of all the personnel involved are necessary to maintain the maximum treatment quality. In this context, national trauma registries, as well as the recently established trauma networks in Germany, might be helpful. Due to improvements in comprehensive trauma care and identification of expensive, but not prognosis improving treatment strategies, costs can be reduced by trauma registries and trauma networks.

BACKGROUND: The mechanism of injury is the major cause for trauma team activation and emergency room resuscitation of trauma victims. To date, it remains unclear to what extent the injury mechanism influences injury pattern and severity. METHODS: A comprehensive systematic literature search based on Medline was carried out. RESULTS: Only a limited number of studies are available which investigated the influence of injury mechanisms on injury patterns and severity. There are no specific mechanisms for traumatic brain and spine injuries. Injuries to the chest and abdomen most frequently resulted from motor vehicle accidents involving passengers sitting on the side of the impact. Steering wheel deformity correlated with the injury severity. Pelvic fractures occurred most frequently due to motor vehicle accidents. The highest mortality resulted from pedestrians being struck by a vehicle and additional loss of life in the same vehicle compartment. CONCLUSIONS: The systematic literature research showed inconsistent results regarding the influence of trauma mechanisms on the resulting injury. Therefore, a treatment algorithm for trauma patients should be independent of the mechanism which is represented in several training programs (e.g. ATLS and PHTLS). However, the mechanism of injury may increase the alertness of the trauma team with respect to injury distribution and severity.

Injuries of great vessels, such as the subclavian or vertebral arteries in childhood are rare. More frequent and therefore better described are dissections of the vertebral artery, which frequently occur following low energy trauma. The combination of dissection of the vertebral and subclavian arteries described in this case study led to sensory affections of the left arm. Therapeutic anticoagulation is the therapy of choice to avoid possible ischemic insults. The therapeutic approach of injuries to the subclavian artery remains unclear and is in the focus of discussions.

INTRODUCTION: Femoral fractures are common injuries in multiple trauma patients. The treatment concept of damage control orthopedics (DCO) is in competition with the concept of early total care (ETC). PATIENTS AND METHODS: In a retrospective study (2003-2007) 73 multiple trauma patients with femoral shaft fractures were included. The cohort was subdivided according to the Injury Severity Score (ISS) (16-24, 25-39 and more than 40) and treatment strategy (ETC versus DCO). Patients were analyzed for outcome and cost aspects. RESULTS: In the patient group with an ISS 16-24 ventilation time and intensive care treatment were longer after DCO treatment, overall costs and deficient cost cover were higher in the DCO group. In the patient group with an ISS 25-39 cost aspects showed a higher cover deficient in the DCO group. CONCLUSION: From an economic point of view the cost deficits for the ETC group were lower than in the DCO group. The treatment strategy should be selected by the pattern of injuries. The costs should be addressed by the Institute for the Hospital Remuneration System (INEK).

BACKGROUND: Multi-drug-resistant bacteria (e.g. Carbapenem-resistant Acinetobacter baumannii, extended-spectrum betalactamase or carbapenemase-producing enterobacteriaceae) are emerging in early-onset infections. So far, there is no report describing the eradication of these bacteria in a osseous infection of an open proximal tibial fracture in combination with the hexapod technology to address both osseous consolidation and closed drop foot correction. CASE PRESENTATION: After sustaining a proximal tibial fracture (Gustilo 3B), a 41-year-old man was primarily treated with open reduction and internal fixation by a locking plate and split-thickness skin graft in the home country. At the time of admission to our hospital there was a significant anterolateral soft tissue defect covered with an already-necrotic split-thickness graft and suspicious secretion. CAT and MRI scans revealed no signs of osseous healing, intramedullary distinctive osteomyelitis, as well as a large abscess zone in the dorsal compartment. Multiple wound smears showed multi-drug-resistant bacteria: Acinetobacter baumannii (Carbapenem resistant) as well as Enterobacter cloacae complex (AmpC overexpression). After implant removal, excessive osseous and intramedullary debridements using the Reamer Irrigator Aspirator (RIA®) as well as initial negative pressure wound therapy were performed. Colistin hand-modelled chains and sticks were applied topically as well as an adjusted systemic antibiotic scheme was applied. After repetitive surgical interventions, the smears showed bacterial eradication and the patient underwent soft tissue reconstruction with a free vascularized latissimus dorsi muscle flap. External fixation was converted to a hexapod fixator (TSF®) to correct primary varus displacement, axial assignment and secure osseous healing. A second ring was mounted to address the fixed drop foot in a closed fashion without further intervention. At final follow-up, 12 months after trauma, the patient showed good functional recovery with osseous healing, intact soft tissue with satisfactory cosmetics and no signs of reinfection. CONCLUSIONS: A multidisciplinary approach with orthopaedic surgeons for debridement, planning and establishing osseous and joint correction and consolidation, plastic surgeons for microvascular muscle flaps for soft tissue defect coverage as well as clinical microbiologists for the optimized anti-infective treatment is essential in these challenging rare cases. LEVEL OF EVIDENCE: Level IV.

PURPOSE: Prehospital estimation of injury severity is essential for prehospital therapy, deciding on the destination hospital and the associated emergency room care. The aim of this study was to compare prehospital estimates of the abbreviated injury scale (AIS) and the Injury Severity Score (ISS) by emergency physicians with the values of AIS and ISS of injury severity determined at the conclusion of diagnostics. METHODS: In this prospective study, the ISS was determined prehospital by emergency physicians. The validated AIS and ISS were analyzed based on final diagnoses. A Bland-Altman plot was used in analyzing the agreement between two different assays as well as sensitivity and specificity were determined. Confidence intervals were calculated for a Wilson score. Significance level was set at p ≤ 0.05. RESULTS: The prehospital ISS was estimated at 26.0 ± 13.0 and was 34.7 ± 16.3 (p < 0.001) after in-hospital validation. In addition, most of the AIS subgroups were significantly higher in the final calculation than preclinically estimated (p < 0.05). When analyzing subgroups of trauma patients (ISS < 16 vs. ISS ≥ 16), we were able to demonstrate a sensitivity of > 90% to identify a multiple-trauma patient. Diagnosing a higher injury severity group (ISS ≥ 25), sensitivity dropped to 61.1%. The Bland-Altman plot demonstrates that injury severity is underestimated in higher injury levels. CONCLUSION: Multiple-trauma patients can be identified using the ISS. Anatomic scores might be used for transport decisions; however, an accurate estimation of the injury severity should also be based on other criteria such as patient status, mechanism of injury, and other triage criteria.

PURPOSE: Patients with multiple injuries are particularly susceptible to accidental hypothermia which is correlated with an increased risk of post-traumatic complications and mortality; however, its impact on neurological outcome in cases where there is concomitant traumatic brain injury is underexplored. METHODS: We analyzed severely injured patients (ISS ≥ 16) including a moderate-to-severe traumatic brain injury (AISHead ≥ 3). The primary endpoint was objective neurological recovery, expressed as Glasgow Outcome Scale (GOS) score at time of discharge. Secondary endpoints were mortality, systemic inflammatory response syndrome (SIRS), sepsis, acute respiratory distress syndrome (ARDS) and multiple organ dysfunction syndrome (MODS). Statistical analysis included logistic regression (odds ratio). The significance level in all analyses was p = 0.05. RESULTS: We analyzed 278 patients (M age = 43 years, SD 19; M ISS = 32.8, SD 10.7). Mortality was 17% (n = 14). 102 patients (37%) were hypothermic on admission. Hypothermic patients were more severely injured (ISS 35.6 ± 11.1 vs. 31.2 ± 10.1, p = 0.001; APACHE II 18.1 ± 7.4 vs. 16.2 ± 7.3, p = 0.045) and had a higher transfusion requirement. Mortality rate in hypothermic patients was increased (23.5 vs. 13.1%, p = 0.03); however, hypothermia was not an independent predictor of mortality. Median GOS at discharge was 3 (IQR 3); in 47% of patients the outcome was favorable (GOS 4 or 5) and 36% it was poor (GOS 2 or 3). There were no differences in post-traumatic complications. Analysis of 73 matched pairs of hypothermic and normothermic patients could not prove hypothermia as an independent predictor of poor neurological outcome (OR 1.7, 95% CI 0.8-3.6, p = 0.1) in the total population. However, older patients (> 41 years) had a 4.2-times higher risk (95% CI 1.4-12.7; p = 0.01) of poor neurological outcome, if they were hypothermic on admission. CONCLUSIONS: Accidental hypothermia seems to have a negative impact on neurological recovery in older patients with multiple injuries including traumatic brain injury which outweighs potential benefits.

Aims: This study aimed to analyze the correlation between transverse process (TP) fractures of the fourth (L4) and fifth (L5) lumbar vertebrae and biomechanical and haemodynamic stability in patients with a pelvic ring injury, since previous data are inconsistent. Patients and Methods: The study is a retrospective matched-pair analysis of patients with a pelvic fracture according to the modified Tile AO Müller and the Young and Burgess classification who presented to a level 1 trauma centre between January 2005 and December 2014. Results: A total of 728 patients with pelvic ring injuries were included, of whom 183 (25.1%) had a biomechanically unstable pelvic fracture. Of these patients, 84 (45.9%) had a fracture of a TP of L4 and/or L5. A total of 73 patients (13.4%) with a stable pelvic ring injury (p < 0.001) had a fracture of a TP. Patients with a fracture of a TP of L4 and/or L5 had a 5.5-fold risk (odds ratio (OR)) of having a biomechanically unstable pelvic injury. TP fractures (OR 1.6, p = 0.2) could not be confirmed as an independent predictor of haemodynamic instability. Conclusion: This is the first study that has demonstrated a positive correlation between a TP fracture of L4 and/or L5 and a biomechanically unstable pelvic ring injury. The presence of transverse process fractures of L4 and/or L5 indicates increased severity of pelvic injury and therefore can help in the planning of emergency treatment.
