[Thrombosis of the subclavian vein after conservative treatment of a clavicular fracture: A rare complication]. / Thrombose der V. subclavia bei konservativ therapierter Klavikulaschaftfraktur: Eine seltene Komplikation.

We report the case of a 16-year-old male patient who presented with a clavicular fracture that was conservatively treated with a redressment bandage. After a few days the patient developed deep vein thrombosis of the subclavian, axillary and brachial veins, which was successfully treated with nadroparin. Conservative treatment of clavicular fractures is a common procedure in modern traumatology. Continuous, close monitoring and knowledge of rare but severe complications are necessary to avoid further complications.

Fixation of acetabular fractures via the ilioinguinal versus pararectus approach: a direct comparison.

This study compared the quality of reduction and complication rate when using a standard ilioinguinal approach and the new pararectus approach when treating acetabular fractures surgically. All acetabular fractures that underwent fixation using either approach between February 2005 and September 2014 were retrospectively reviewed and the demographics of the patients, the surgical details and complications were recorded. A total of 100 patients (69 men, 31 women; mean age 57 years, 18 to 93) who were consecutively treated were included for analysis. The quality of reduction was assessed using standardised measurement of the gaps and steps in the articular surface on pre- and post-operative CT-scans. There were no significant differences in the demographics of the patients, the surgical details or the complications between the two approaches. A significantly better reduction of the gap, however, was achieved with the pararectus approach (axial: p = 0.025, coronal: p = 0.013, sagittal: p = 0.001). These data suggest that the pararectus approach is at least equal to, or in the case of reduction of the articular gap, superior to the ilioinguinal approach. This approach allows direct buttressing of the dome of the acetabulum and the quadrilateral plate, which is particularly favourable in geriatric fracture patterns.

Skeletal metastatic disease of the femur: results by management with intramedullary nailing.

PURPOSE OF THE STUDY This study aimed to analyse the outcome following intramedullary nailing for metastases of the femur in a large cohort with special regard to mechanical, implant associated complications and patient survival. Furthermore, we aimed to identify factors influencing the overall survival. MATERIAL AND METHODS All patients (n = 74) that underwent intramedullary nailing for metastatic disease of the femur between 2004 and 2008 and were retrospectively reviewed. Data were recorded from the patients' medical record and the outpatients' clinics files. Details about the tumour biology, the surgery performed as well as the postoperative care were documented. Survival data were extracted from patient records or obtained via communication with outpatient oncologists or the community registration office. RESULTS 74 (28 (37.8%) male, 46 (62.2%) female; p = 0.048) patients with a mean age of 64.4 ± 11.7 years were included. Breast (25, 33.8%), lung (18, 24.3%), bone marrow (7, 9.5%) and kidney (6, 8.1%) were the primary tumours in more than 75% of all patients. The mean overall survival was 17.5 (95% CI: 9.6 - 25.5) months. Patients with osseous metastases had a significant longer survival than patients with visceral and/or cerebral metastases (p = 0.025 and p = 0.032). CONCLUSION Intramedullary nailing represents a valuable fixation method for pathologic fractures or impending fractures of the femur in patients with an advanced stage of metastatic disease. It provides adequate stability to outlast the patient s remaining life-span. However, the balance must be found between therapeutic resignation and surgical overtreatment since operative treatment may be accompanied with serious complications. Key words: bone metastases, intramedullary nailing, metastatic disease, cement augmentation, osteolytic defect.

Functional and radiological outcome of periprosthetic fractures of the ankle.

The incidence of periprosthetic fractures of the ankle is increasing. However, little is known about the outcome of treatment and their management remains controversial. The aim of this study was to assess the impact of periprosthetic fractures on the functional and radiological outcome of patients with a total ankle arthroplasty (TAA). A total of 505 TAAs (488 patients) who underwent TAA were retrospectively evaluated for periprosthetic ankle fracture: these were then classified according to a recent classification which is orientated towards treatment. The outcome was evaluated clinically using the American Orthopedic Foot and Ankle Society (AOFAS) score and a visual analogue scale for pain, and radiologically. A total of 21 patients with a periprosthetic fracture of the ankle were identified. There were 13 women and eight men. The mean age of the patients was 63 years (48 to 74). Thus, the incidence of fracture was 4.17%. There were 11 intra-operative and ten post-operative fractures, of which eight were stress fractures and two were traumatic. The prosthesis was stable in all patients. Five stress fractures were treated conservatively and the remaining three were treated operatively. A total of 17 patients (81%) were examined clinically and radiologically at a mean follow-up of 53.5 months (12 to 112). The mean AOFAS score at follow-up was 79.5 (21 to 100). The mean AOFAS score in those with an intra-operative fracture was 87.6 (80 to 100) and for those with a stress fracture, which were mainly because of varus malpositioning, was 67.3 (21 to 93). Periprosthetic fractures of the ankle do not necessarily adversely affect the clinical outcome, provided that a treatment algorithm is implemented with the help of a new classification system.

Complication rates and reduction potential of palmar versus dorsal locking plate osteosynthesis for the treatment of distal radius fractures.

BACKGROUND: The aim of this study was to evaluate the complication rates of volar versus dorsal locking plates and postoperative reduction potential after distal radius fractures. MATERIALS AND METHODS: For this study 285 distal radius fractures (280 patients/59.4 % female) treated with locked plating were retrospectively evaluated. The mean age of the patients was 54.6 years (SD 17.4) and the mean follow-up was 33.2 months (SD 17.2). The palmar approach was used in 225 cases and the dorsal approach in 60 cases (95 % type C fractures). RESULTS: Adequate reduction was achieved with both approaches, regardless of fracture severity. In the dorsal group, the complications and implant removal rates were significantly higher and the operative time was also longer. CONCLUSIONS: Based on these facts, we advocate the palmar locking plate for the vast majority of fractures. In cases of complex multifragmentary articular fractures where no compromise in reduction is acceptable, and with the biomechanical equality of palmar and dorsal plating remaining unproven, dorsal plating may still be considered. LEVEL OF EVIDENCE: Therapeutic level IV.

[Osseous tuberculosis as a rare differential diagnosis of femoral head necrosis]. / Ossäre Tuberkulose als seltene Differenzialdiagnose der Femurkopfnekrose.

BACKGROUND: We report on a 60-year-old immunocompetent German male patient without risk factors, who had been suffering from pain in the right hip for 8 months. DIAGNOSTICS: Radiographs showed destruction of the femoral head with a collapse of the main weight-bearing area, which was interpreted as femoral head necrosis. THERAPY: A cement-free total hip prosthesis was then implanted. The femoral head was sent for routine histological analysis and PCR amplification yielded a positive result for Mycobacterium tuberculosis complex DNA, leading to immediate guideline-based tuberculostatic treatment. CONCLUSION: Tuberculosis should be considered as a differential diagnosis in the case of destruction of the femoral head, especially in immunocompromised patients, patients with a foreign background or destructive osteoarthritis of the hip with an atypical course. Antibiotic treatment is necessary postoperatively. Under this therapy, a good clinical outcome can be expected comparable to that achieved in patients with primary osteoarthritis without infection.

Requirement for a structured algorithm in cardiac arrest following major trauma: epidemiology, management errors, and preventability of traumatic deaths in Berlin.

BACKGROUND: Despite continuous innovation in trauma care, fatal trauma remains a significant medical and socioeconomic problem. Traumatic cardiac arrest (tCA) is still considered a hopeless situation, whereas management errors and preventability of death are neglected. We analyzed clinical and autopsy data from tCA patients in an emergency-physician-based rescue system in order to reveal epidemiologic data and current problems in the successful treatment of tCA. MATERIAL AND METHODS: Epidemiological and autopsy data of all unsuccessful tCPR cases in a one-year-period in Berlin, Germany (n=101, Group I) and clinical data of all cases of tCPR in a level 1 trauma centre in an 6-year period (n=52, Group II) were evaluated. Preventability of traumatic deaths in autopsy cases (n=22) and trauma-management failures were prospectively assessed. RESULTS: In 2010, 23% of all traumatic deaths in Berlin received tCPR. Death after tCPR occurred predominantly prehospital (PH;74%) and only 26% of these patients were hospitalized. Of 52 patients (Group II), 46% required tCPR already PH and 81% in the emergency department (ED). In 79% ROSC was established PH and 53% in the ED. The survival rate after tCPR was 29% with 27% good neurological outcome. Management errors occurred in 73% PH; 4 cases were judged as potentially or definitive preventable death. CONCLUSION: Trauma CPR is beyond routine with the need for a tCPR-algorithm, including chest/pericardial decompression, external pelvic stabilization and external bleeding control. The prehospital trauma management has the highest potential to improve tCPR and survival. Therefore, we suggested a pilot prehospital tCPR-algorithm.

[Complications after osteosynthetic treatment of acetabular fractures]. / Komplikationen nach osteosynthetischer Versorgung von Azetabulumfrakturen.

The early work of Judet and Letournel in the 1970s and 1980s led to a paradigm shift in the treatment of acetabular fractures. The previously purely conservative treatment was replaced more and more by open surgical approaches. The complex, three-dimensional bony anatomy and the periacetabular soft tissue with a close topographic relationship to intrapelvic and extrapelvic neurovascular and visceral structures implicate an increased rate as well as a high risk for intraoperative and postoperative complications. Simultaneously, anatomical reconstruction with a gap step-off less than 1-2 mm is required. Fractures of the acetabulum are comparatively rare and only few trauma centers have the capability and the infrastructure to treat acetabular fractures. Therefore, the aim of this review was to illustrate the possible intraoperative and postoperative complications of osteosynthetic treatment of acetabular fractures as well as to identify possible strategies for treatment and prevention.

[CT-based classification aid for acetabular fractures: evaluation and clinical testing]. / CT-basierten Klassifikationshilfe für Acetabulumfrakturen: Evaluation und klinische Erprobung.

BACKGROUND: The basis for the classification of acetabular fractures depends on accurate radiological diagnostics. The use of conventional X-rays alone implicates a low intrapersonal reproducibility and interpersonal reliability. By applying computed tomography (CT) at an early stage in the emergency room, the typical diagonal X-rays of ala and obturator, on which the classification is based, are no longer recommended. The aim of this study was to develop a new reliable classification system based on standardized CT slices according to the system of Judet and Letournel without using diagonal X-rays. MATERIALS AND METHODS: In this study 12 select cases with acetabular fractures were peer reviewed. In each case eight characteristic CT slices (five axial, two coronal and one sagittal) were selected as well as the conventional anteroposterior X-ray of the pelvis. All cases were peer reviewed by 14 members of the "AG Becken" (working group pelvis). The classification of the acetabular fractures was based on Judet and Letournel and the results were compared with the reference classification. The results were scaled according to differences to the original classification and the relevance to the approach as well as the medical qualification of the member. RESULTS: A total of 167 out of 168 possible classifications were conducted, 90 cases (54 %) were in accordance with the reference classification. In 69 cases (41 %) the outcome was different, which would have had no influence on the choice of the surgical approach. A wrong classification was present eight times (5 %). According to the medical qualification status the senior physicians were right in 54%, the residents in 53 %. Within the group of senior physicians 7.5 % of the classifications were completely wrong and 93 % of the participating members would have preferred to have more CT slices. CONCLUSION: The CT-based classification developed represents an adaption to the current standard of diagnostics of acetabular fractures and represents a step towards simplification of the classification. It is suitable to estimate the correct surgical approach and the behavior of the fracture. For an accurate classification and the association to one of the fracture types in the system of Judet and Letournel more slices and 3D reconstructions (MPR) are necessary.

[Arthroscopic correction of extra-articular subspinal impingement in the hip joint]. / Arthroskopische Korrektur des extraartikulären Subspine-Impingements am Hüftgelenk.

We report the case of symptomatic extra-articular subspinal impingement in the hip joint caused by a pathological contact between the anterior inferior iliac spine (AIIS) and the femoral neck. A 28-year-old patient presented with activity-related inguinal pain on the right side and a positive anterior impingement test in the clinical examination. Radiological examinations revealed a hypertrophic AIIS with caudal extension below the acetabulum. After a positive injection test confirmed the AIIS as the origin of the pain, arthroscopic correction with partial resection of the AIIS was performed resulting in significant pain relief and improved range of motion.

[Solitary spinal metastases. Is aggressive surgical management justified?]. / Solitäre Metastasen der Wirbelsäule. Indikationen für eine aggressive chirurgische Therapie?

Advances in oncological and surgical therapies have led to a significant increase in life expectancy of cancer patients and also prolonged survival of patients with isolated or multiple metastases. Among the skeletal manifestations the spine is the most often affected site. Using novel imaging techniques with higher resolution and use of metabolic signatures, the screening of cancer patients has improved considerably. Consequently, the diagnosis of metastases is becoming increasingly more sensitive. Therefore, but also due to more effective polychemotherapy protocols, singular or solitary metastases are more frequently observed either in the early stages or as a result of a controlled malignant tumor entity (stable disease). The questions whether a solitary metastasis really exists (illusion or reality?) and its radical oncological and surgical treatment as a circumscribed singular tumor manifestation, is really relevant for the overall prognosis, remains controversial. However, it seems evident that a biologically favorable underlying tumor biology, radical treatment of the primary tumor and a long metastasis-free interval are valid predictors of a good oncological outcome. In the presence of a solitary metastasis under these circumstances (typical example: solitary metastasis of renal cell carcinoma many years after radical tumor nephrectomy) a radical surgical procedure (en bloc spondylectomy) can significantly improve the long-term prognosis of this patient group in combination with adjuvant chemotherapy and/or radiotherapy. However, a thorough evaluation of the overall survival prognosis, a detailed and complete staging followed by a treatment consensus in the interdisciplinary tumor board has to precede any therapeutical decisions.

Trauma-related preventable deaths in Berlin 2010: need to change prehospital management strategies and trauma management education.

BACKGROUND: Fatal trauma is one of the leading causes of death in Western industrialized countries. The aim of the present study was to determine the preventability of traumatic deaths, analyze the medical measures related to preventable deaths, detect management failures, and reveal specific injury patterns in order to avoid traumatic deaths in Berlin. MATERIALS AND METHODS: In this prospective observational study all autopsied, direct trauma fatalities in Berlin in 2010 were included with systematic data acquisition, including police files, medical records, death certificates, and autopsy records. An interdisciplinary expert board judged the preventability of traumatic death according to the classification of non-preventable (NP), potentially preventable (PP), and definitively preventable (DP) fatalities. RESULTS: Of the fatalities recorded, 84.9 % (n = 224) were classified as NP, 9.8 % (n = 26) as PP, and 5.3 % (n = 14) as DP. The incidence of severe traumatic brain injury (sTBI) was significantly lower in PP/DP than in NP, and the incidence of fatal exsanguinations was significantly higher. Most PP and NP deaths occurred in the prehospital setting. Notably, no PP or DP was recorded for fatalities treated by a HEMS crew. Causes of DP deaths consisted of tension pneumothorax, unrecognized trauma, exsanguinations, asphyxia, and occult bleeding with a false negative computed tomography scan. CONCLUSIONS: The trauma mortality in Berlin, compared to worldwide published data, is low. Nevertheless, 15.2 % (n = 40) of traumatic deaths were classified as preventable. Compulsory training in trauma management might further reduce trauma-related mortality. The main focus should remain on prevention programs, as the majority of the fatalities occurred as a result of non-survivable injuries.

[Rescue time and survival of severely injured patients in Germany]. / Rettungszeit und Überleben von Schwerverletzten in Deutschland.

BACKGROUND: Independent of the rescue system type, a rescue time of less than 60 min for trauma patients is usually required and considered to be crucial for the outcome. The goal of this study was to investigate the impact of the rescue time on hospital survival in severely injured patients. METHODS: With the help of the German Trauma Registry of the DGU, the population and rescue time were systematically analyzed with regard to the survival rate. A lower mortality rate was observed with a higher injury severity in metropolitan cities compared to small towns. RESULTS: A multivariate regression analysis revealed no clinically relevant impact of the rescue time length in the German rescue system on survival. This can be explained by a higher amount of preclinical medical procedures during longer rescue times. CONCLUSIONS: Within the German rescue system, the length of rescue time has no relevant impact on the survival of trauma patients admitted to a clinic. This could be explained by the higher numbers of preclinical measures and due to the limitations of a register study with selection bias. Therefore, we advocate that the necessary and suitable preclinical medical procedures be performed to stabilize the patient, even in cases that have exceeded the 60-min gold standard time window. In conclusion the "golden hour" concept today might better be interpreted as an individual and appropriate "golden period" of trauma.

[Implementation of the eLearning project NESTOR. A network for students in traumatology and orthopedics]. / Implementierung des eLearning-Projekts NESTOR. Ein Netzwerk für Studierende der Traumatologie und Orthopädie.

BACKGROUND: Modern internet-based information technologies offer great possibilities to create and improve teaching methods for students. The eLearning tool NESTOR (Network for Students in Traumatology and Orthopedics) presented here was designed to complement the existing clinical teaching in orthopedics and traumatology at the Charité, University Medicine Berlin. MATERIALS AND METHODS: Using a learning management system, videos, podcasts, X-ray diagnosis, virtual patients, tests and further tools for learning and study information were combined. After implementation the eLearning project was evaluated by students. RESULTS: The NESTOR project offers various possibilities for knowledge acquisition. Students using the program voluntarily showed a high acceptance whereby 82.4% were very satisfied with the contents offered and 95.3% supported the idea of a future use of NESTOR in teaching. The blended learning approach was positively evaluated by 93.5% of the students. The project received the eLearning seal of quality of the Charité University Medicine Berlin. CONCLUSION: Using complex eLearning tools, such as the NESTOR project represents a contemporary teaching approach in the teaching of traumatology and orthopedics and should be offered in a blended learning context as they are well accepted by students.

[Coincidence of traumatic tracheal rupture accompanied by ARDS. Illustrated by the example of a 17-year-old patient with multiple injuries]. / Koinzidenz der traumatischen Trachealruptur mit begleitendem ARDS. Beispiel anhand eines 17-jährigen polytraumatisierten Patienten.

Treatment and diagnosis of a traumatic tracheal rupture is a challenge. Due to the rarity of such injuries and the subtle and delayed clinical presentation it is difficult to diagnose. We present for the first time the successful management of a 17-year-old multiply injured patient with coincidental tracheal rupture and ARDS (acute respiratory distress syndrome) after a fall. Besides the case report and pathogenesis the essential diagnostic and therapeutic measures are mentioned and discussed. The circumstances surrounding the accident have to be balanced with the severity of the trauma to also exclude rare injuries with certainty. Finally level 1 trauma centers specialized in ARDS provide the best clinical setting for successful treatment of these life-threatening injuries.

Surgical management of recurrent thoracolumbar spinal sarcoma with 4-level total en bloc spondylectomy: description of technique and report of two cases.

INTRODUCTION: The descriptions of total spondylectomy and further development of the technique for the treatment of vertebral sarcomas offered for the first time the opportunity to achieve oncologically sufficient resection margins, thereby improving local tumor control and overall survival. Today, single level en bloc spondylectomies are routinely performed and discussed in the literature while only few data are available for multi-level resections. However, due to the topographic vicinity of the spinal cord and large vessels, the multisegmental resections are technically demanding, represent major surgery and only few case reports are available. Surgical options are even more limited in cases of revision surgery and local recurrences when en bloc spondylectomy was considered to be not feasible due to high risk of vital complications in expanding resection margins. Deranged anatomy, implants in situ and extensive intra-/paraspinal scar tissue formation resulting from previously performed approaches and/or radiation are considered the principal complicating factors that usually hold back spine surgeons to perform revision for resection leaving the patient to palliative treatment. METHODS: We present two patient cases with previously performed piecemeal vertebrectomy in the thoracic spine due to a solitary high-grade spinal sarcoma. After extensive re-staging, both patients underwent a multi (4)-level en bloc spondylectomy in our department (one patient with combined en bloc lung resection). Except a local wound disturbance, there was no severe intra- or postoperative complication. RESULTS: After multilevel en bloc spondylectomy both patients showed a good functional outcome without neurological deficits, except those resulting from oncologically scheduled resection of thoracic nerve roots. After a median follow-up of 13 months, there was no local recurrence or distant metastasis. The reconstruction using a posterior screw rod system that is interconnected to an anterior vertebral body replacement with a carbon composite cage showed no implant failure or loosening. In summary, the approach of a multilevel en bloc surgery for revision and oncologically sufficient resection in cases of spinal sarcoma recurrences seems possible. However, interdisciplinary decision making in a tumor board, realistic evaluation of surgical resectability to attain tumor free margins, advanced experiences in spinal reconstructions and involvement of vascular, visceral and thoracic surgical expertise are essential preconditions for acceptable oncological and functional outcome.

[Locking plates for osteosyntheses of corrective osteotomies in paediatric orthopaedic and neuroorthopaedic patients]. / Winkelstabile Implantate zur Osteosynthese nach Korrekturosteotomien in der Kinder- und Neuroorthopädie.

BACKGROUND: Modern locking plates are widely used for the treatment of adult orthopaedic and trauma patients. Sporadic descriptions of their advantages now exist for paediatric trauma patients. Publications concerning their implantation in paediatric orthopaedic and neuroorthopaedic patients are still scarce even though it is well known that the compliance of children and adolescents is limited and that rapid mobilisation is essential for patients with disorders of neurological origin or bone metabolism to avoid developmental setbacks and perioperative fractures. PATIENTS AND METHODS: The principle of the locking plate system also described as internal fixateur is based on the thread bolting of the screwheads within the plate. This results in high initial stability and thus high initial loading capacity. Furthermore, it is possible to preserve soft tissue and periosteum which leads to less impaired biological bone healing. Between February 2008 and March 2010 locking plates were used for osteosynthesis in our department in 16 paediatric patients with 20 corrective osteotomies. All patients suffered from either neurological disorders or diseases with alteration of the bone metabolism. The outcome was analysed concerning safety, complications, practicability, mobilisation, consolidation of the osteotomy, loss of correction, as well as complications with the removal of the implants. RESULTS: Seven of the treated patients suffered from neurological disorders such as cerebral palsy or spina bifida, 9 patients had diseases with local or systemic alteration of their bone metabolism such as vitamin D deficiency and phosphate diabetes. The average age of the patients at the time of surgery was 11.18 (5-18) years. Implant-associated complications were not seen in this patient group, especially no implant failures. Mobilisation was achieved without cast treatment with at least partial weight-bearing within the first postoperative week in most cases. Loss of correction or problems with implant removal did not occur. 18 of the 20 osteotomy sites were completely healed at the 12 week follow-up. CONCLUSION: Locking plates are a safe and effective treatment device not only for adult trauma patients but also for the treatment of children and adolescents. When stabilisation of corrective osteotomies is performed with locking plates especially young patients benefit from this technique since mobilisation can be started earlier as compared to the use of non-angle stable plates or wires and cast immobilisation becomes unneccessary. The surgeon needs to know the range of products to pick the best implant regarding the growing skeleton's special anatomy. When choosing implants for patients with reduced bone density or impaired motor abilities as in cerebral palsy, spina bifida, and other systemic disorders, locking plates have to be taken into account to facilitate mobilisation and to avoid setbacks in motor development as well as pressure ulcers from casts. Clinical studies have to evaluate if early mobilisation combined with shorter inpatient treatment and less time and cost consuming postoperative physiotherapy or rehabilitation justify the use of the more expensive locking plates for the treatment of otherwise healthy patients.
