Abstract
BACKGROUND Non-unions and chronic instability of the pelvis remain rare complications after complex high velocity injuries with vertical and rotational instability of the pelvis. Treatment options are insufficiently supported by data evidence due to the rareness of this condition. PATIENTS AND METHODS we conducted a single center, retrospective study of all non-unions and pelvic instabilities between 1.1.2008 and 1.1.2019, excluding fragility fractures. Patients' characteristics, fracture patterns, procedures and outcomes with regard to developing treatment options and successful union in the follow-up were obtained. RESULTS 26 patients were included in this retrospective analysis. The mean age was 55 years (range 34-78 years). Seventy-seven percent of the patients were male. The standard procedure consisted of radical debridement of the non-union, interposition of autologous bone graft and rigid stabilization systems. Three patients were lost to follow up. In the remaining n = 23 patients (88%) consolidation of the non-union was achieved. The mean follow up was 31.3 months (range 6-144). Follow up showed that an iliolumbar fixation seems to be favorable regarding outcome and complications. DISCUSSION Non-union and remaining instability of the pelvic ring represent a rare complication after high grade pelvic trauma. There are only limited data regarding the incidence and the treatment regimen is based on small study populations only. Based on our findings we recommend to combine autologous bone grafts with rigid fixation systems especially for non-union of the pelvis to restore the posterior sacroiliac arch.

Abstract
End-of-stem pain after knee and hip arthroplasty with diaphyseal supportive stems is a frequently overlooked and potentially underestimated complication. A commonly recurring clinical phenome is the symptom-free interval after surgery of weeks to months, with new onset of symptoms under stress only later. The patient is often again reliant on walking sticks. End-of-stem pain is a diagnosis of exclusion. Pain is projected into the tip of the stem, and if differential diagnoses such as loosening are excluded, then the patient might be treated with a "bending-plate". Since bone cement has a similar elastic modulus to human cortical bone, a change of method to a cemented implant can also be expedient. In the primary situation, in addition to cemented stems, the use of "split-stems" could be useful. After revision surgery of any kind, a timely cessation of pain confirms the diagnosis.

Abstract
Background Minimally invasive, thoracoscopic anterior spondylodesis (MIAS) is an established treatment for burst fractures of the thoracolumbar spine. Good restoration of the local sagittal alignment and good functional results have been reported. The aim of this study was to evaluate long-term results of MIAS in patients with incomplete burst fractures and to analyze the influence on global sagittal alignment, clinical outcomes, and adjacent segment degeneration. Methods From 2002 to 2003, 18 patients were treated with MIAS for incomplete thoracolumbar burst fractures. Mono-segmental spondylodesis was performed with an iliac crest bone graft and bisegmental spondylodesis with a titanium cage. In this single-center prospective cohort study, 15 patients were available for follow-up (FU) after an average of 12.9 years (12.1–14.4). Seven patients were treated with a combined anterior and posterior instrumentation and eight patients with anterior spondylodesis only. The primary clinical outcome parameter was the Oswestry Disability Index (ODI); secondary parameters were the Short Form 36 (SF36) and the visual analog scale (VAS spine). Full spine radiographs were assessed for bisegmental Cobb angle, alignment parameters, and signs of adjacent segment degeneration (ASD). Results ODI evaluation showed a mean impairment of 11.7% with minimal limitations in 13 patients. Neither a significant deterioration over time nor significant differences between both therapy strategies were found in the clinical scores at the latest follow-up. The mean bisegmental increase of regional malalignment of reduction was 8.8° (± 7.3°) with no significant correlation to any clinical outcome scores. The majority of patients had no signs of adjacent segment degeneration. Two patients showed minor radiologic changes. All patients had a balanced sagittal spine profile. Conclusions In conclusion, MIAS leads to good clinical results with—in majority—minimal spine-related impairment at the latest follow-up. No significant deterioration at 12-year FU was detectable compared to the 6-year results for the SF36 and VAS spine scores. There was no association between sagittal alignment, clinical outcome scores, and ASD. Trial registration The study was retrospectively registered in the German Clinical Trials Register (Nr.00015656).

Abstract
Key factors for successful osteosynthetic fracture stabilization are anatomical fracture reduction, restoration of axis and torsion alignment as well as tissue-preserving operative techniques. In long bone fractures, the use of intramedullary long bridging nailing offers ideal conditions for bone healing, as axial and rotational stability is provided by canal-filling nails and locking screws. In addition, the tissue in the fracture region is protected as the intramedullary nail insertion is distant from the fracture. The indication spectrum for modern intramedullary locked nailing includes diaphyseal fractures of long bones, metaphyseal fractures and reconstructions, as well as treatment of nonunion, osteotomy and arthrodesis of the lower extremities. Continuous improvements in nail design and instrumentation as well as the introduction of anatomical reconstruction nails will optimize the spectrum and effectiveness of intramedullary osteosynthesis even further.

Abstract
BACKGROUND Aim of this study was to compare the clinical and radiological long-term outcomes following operative treatment of comminuted radial head fractures using 1) primary radial head resection arthroplasty, 2) acute radial head resection, or 3) necessary secondary prosthetic removal. Additionally, we evaluated complex radial head fractures combined with elbow dislocation and verified the hypothesis of whether primary radial head resection arthroplasty could contribute to ligament healing. METHODS In a comparative retrospective cohort study between 2004 and 2014, 87 (33 female, 54 male) patients with comminuted radial head fractures with a median age of 45 (range 18-77) years were included and followed-up clinically and radiologically. Functional results were evaluated according to MEPS, DASH, Broberg and Morrey, and VAS scores. RESULTS After a median range of 46 months postoperatively, 48 patients (group 1) obtained an acute radial head resection arthroplasty (MEPS: 70 points, Broberg and Morrey: 63 points, DASH: 34 points, VAS: 3.3 points). Twenty patients (group 2) were treated by radial head resection (MEPS: 63 points, Broberg and Morrey: 50 points, DASH: 49 points, VAS 4.2 points) and 19 patients (group 3) needed secondary prosthesis removal (MEPS: 73 points, Broberg and Morrey: 66 points, DASH: 38 points, VAS: 2.8 points). The overall outcome demonstrated a trend towards better results and the Kellgren-Lawrence grade of postoperative osteoarthritis was significantly better in groups 1 and 3 compared to group 2 (P=0.02). CONCLUSION Clinical and radiological long-term results of this study demonstrate a trend towards a better outcome after acute radial head resection arthroplasty compared to primary radial head resection, especially in complex fractures associated with elbow dislocation. Furthermore, our results encourage the use of primary radial head replacement in cases of comminuted non-reconstructable radial head fractures.

Abstract
OBJECTIVE Determining differences in neurological and functional outcome between adolescents and adults after acute traumatic spinal cord injury (SCI). DESIGN Retrospective, multi-center case-control study. METHODS 100 cases of patients under 18 years at accident with acute traumatic cervical SCI admitted to SCI centers participating in the European Multi-center study about SCI (EMSCI) between January 2005 and April 2016 were reviewed. According to their age at accident, age 13 to 17, patients were selected for the adolescent group. After applying in- and exclusion criteria 32 adolescents were included. Each adolescent patient was matched with two adult SCI patients for analysis. OUTCOME MEASURES ASIA Impairment scale (AIS) grade, neurological, sensory, motor level, total motor score, and Spinal Cord Independence Measure (SCIM III) total score. RESULTS Mean AIS conversion, neurological, motor and sensory levels as well as total motor score showed no significantly statistical difference in adolescents compared to the adult control group after follow up of 6 months. Significantly higher final SCIM scores (p < 0.05) in the adolescent group compared to adults as well as a strong trend for a higher gain in SCIM score (p < 0.061) between first and last follow up was found. CONCLUSIONS Neurological outcome after traumatic cervical SCI is not superior in adolescents compared to adults in this cohort. Significantly higher SCIM scores indicate more functional gain for the adolescent patients after traumatic cervical SCI. Juvenile age appears to be an independent predictor for a better functional outcome.

Abstract
CONTEXT Sublesional osteoporosis is an important sequel after spinal cord injury (SCI) resulting in a high incidence of fractures and impaired osseous healing due to altered bone metabolism. The following study aims to identify demographic characteristics and outcome of patients with SCI with lower extremity fractures. DESIGN Retrospective observational study. SETTING Level-I cross-regional trauma center. PARTICIPANTS All patients with SCI suffering from osteoporotic/pathologic fractures during an 11-year-period (01/2003-12/2013) at the Center for Spinal Cord Injuries (Trauma Center Murnau) were analyzed via a chart review. OUTCOME MEASURES Demographics, surgical and radiologic outcome as well as complication rate were assessed with a special emphasis on union rates and independent risk factors for non-unions. RESULTS We identified 132 patients (105 males) who fulfilled the inclusion criteria. Most of them were paraplegic (n=101) and showed motor complete syndromes (n=119). Supracondylar femur fractures were the most prevalent in this study (n=47). We observed a non-union rate of 15.9% (n=21). The development of pseudarthrosis was associated with the time interval since the initial SCI (P < 0.010), delayed in-patient submission (P < 0.038), fracture classification (P < 0.002) and the localization of the fracture (P < 0.0001). The overall complication rate was 16.7%. All dislocated subtrochanteric femur fractures (Garden III and IV) (n=10) developed a non-union, regardless of their management (conservative or surgical). The following independent predictors for non-unions were identified: fracture localization (P < 0.0002), fracture classification (P < 0.056), and fracture management (P < 0.036). CONCLUSIONS Even though modern techniques allow surgical interventions in bones with reduced mineral density, non-unions remain a common complication in patients with SCI. Risk factors for non-unions of lower extremity fractures are identified.

Abstract
Introduction Aim of this retrospective analysis of prospectively collected data was to evaluate the functional mid-term outcome two years after open reduction and internal fixation of acetabular fractures involving the anterior column with affection of the quadrilateral plate using the pararectus approach on a large cohort. Method Fifty-two patients (12 female, 40 male) with a median age of 55 (range 18–90) years and displaced acetabular fractures involving the anterior column were surgically treated in a single level I trauma centre between July 2012 and February 2016 using the pararectus approach. Thirty-four patients (8 female and 26 male) with a median age of 58 (range 20–85) years were available for complete clinical follow-up at regular intervals, finally 24 months post-operatively. Functional outcome was evaluated according to modified Merle d’Aubigné score, Lower Extremity Functional Scale, WOMAC, and SF-36. Results Range of time between trauma and surgical treatment was three (range 0–19) days. Operation time was 140 (range 60–240) minutes, and duration of hospital treatment was 19 (range 7–38) days. Functional results in 34 patients available for final follow-up demonstrated 68 points (median; range 39–80) according to the Lower Extremity Functional Scale, 6% according to the WOMAC (mean; SD ± 14.5%), and 69% (mean; SD ± 20.1%) according to the SF-36. The modified Merle d’Aubigné score was excellent in 22 patients, good in eight patients, and fair in four patients. Discussion/conclusion Based on the good to excellent functional mid-term follow-up results of this study, the pararectus approach can be recommended as sufficient alternative single access to address displaced acetabular fractures involving the anterior column, independent of patients’ age.

Abstract
Background The aim of the study was to analyze the effect of local infiltration analgesia (LIA), peripheral nerve blocks, general and spinal anesthesia on early functional recovery and pain control in primary unicompartmental knee arthroplasty (UKA). Methods Between January 2016 until August 2016, 134 patients underwent primary UKA and were subdivided into four groups according to their concomitant pain and anesthetic procedure with catheter-based techniques of femoral and sciatic nerve block (group GA&FNB, n = 38) or epidural catheter (group SP&EPI, n = 20) in combination with general anesthesia or spinal anesthesia, respectively, and LIA combined with general anesthesia (group GA&LIA, n = 46) or spinal anesthesia (group SP&LIA, n = 30). Outcome parameters focused on the evaluation of pain (NRS scores), mobilization, muscle strength and range of motion up to 7 days postoperatively. The cumulative consumption of (rescue) pain medication was analyzed. Results The LIA groups revealed significantly lower (about 50%) mean NRS scores (at rest) compared to the catheter-based groups at the day of surgery. In the early postoperative period, the dose of hydromorphone as rescue pain medication was significantly lower (up to 68%) in patients with SP&EPI compared to all other groups. No significant differences could be detected with regard to grade of mobilization, muscle strength and range of motion. However, there seemed to be a trend towards improved mobilization and muscle strength with general anesthesia and LIA, whereof general anesthesia generally tended to ameliorate mobilization. Conclusions Except for a significant lower NRS score at rest in the LIA groups at day of surgery, pain relief was comparable in all groups without clinically relevant differences, while the use of opioids was significantly lower in patients with SP&EPI. A clear clinically relevant benefit for LIA in UKA cannot be stated. However, LIA offers a safe and effective treatment option comparable to the well-established conventional procedures.

Abstract
BACKGROUND Postoperative pain control and enhanced mobilization, muscle strength and range of motion following total knee arthroplasty (TKA) are pivotal requisites to optimize rehabilitation and early recovery. The aim of the study was to analyze the effect of local infiltration analgesia (LIA), peripheral nerve blocks, general and spinal anesthesia on early functional recovery and pain control in primary total knee arthroplasty. METHODS Between January 2016 until August 2016, 280 patients underwent primary TKA and were subdivided into four groups according to their concomitant pain and anesthetic procedure with catheter-based techniques of femoral and sciatic nerve block (group GA&FNB, n = 81) or epidural catheter (group SP&EPI, n = 51) in combination with general anesthesia or spinal anesthesia, respectively, and LIA combined with general anesthesia (group GA&LIA, n = 86) or spinal anesthesia (group SP&LIA, n = 61). Outcome parameters focused on the evaluation of pain (NRS scores), mobilization, muscle strength and range of motion up to 7 days postoperatively. The cumulative consumption of (rescue) pain medication was analyzed. RESULTS Pain relief was similar in all groups, while the use of opioid medication was significantly lower (up to 58%) in combination with spinal anesthesia, especially in SP&EPI. The LIA groups, in contrast, revealed significant higher mobilization (up to 26%) and muscle strength (up to 20%) in the early postoperative period. No analgesic technique-related or surgery-related complications occurred within the first 7 days. Due to insufficient pain relief, 8.4% of the patients in the catheter-based groups and 12.2% in the LIA groups resulted in a change of the anesthetics pain management. CONCLUSIONS The LIA technique offers a safe and effective treatment option concerning early functional recovery and pain control in TKA. Significant advantages were shown for mobilization and muscle strength in the early postoperative period while pain relief was comparable within the groups.

Abstract
The standard treatment for patella fractures is tension band wiring. However, with tension band wiring anatomical reduction and rigid fixation can be challenging and the clinical outcome after patella fracture is often not satisfying. The purpose of this prospective clinical observation was to evaluate the clinical outcome in patients with patella fractures treated with an angular stable patella plate. Between 2011 and 2015 a total of 67 patients were treated with an angular stable patella plate. Outcome in these patients was evaluated by the Knee Outcome Survey Activities of Daily Living Scale (KOS-ADL) and range of motion of the knee joint was assessed. Complete follow up was obtained for 35 patients. In these patients, we found one implant-related complication. None of the patients reported any deficits in extension capabilities. The flexion was on average 127° (SD 21°). The patients classified the function of their knee in daily life on average with 77% (SD 24%) in comparison to their function before the trauma. Only kneeling or squatting was a problem in some patients. In conclusion, angular stable patella plating appears to be a promising alternative treatment for patella fractures. The patella plate provides increased mechanical stability for fracture fixation which appeared to result in a reduction of complications and improvement of functional outcome compared to tension band wiring. Especially patients with a multi-part or comminuted fracture or with osteoporotic bone are likely to benefit from the stability provided by the plate and the locking screws.

Abstract
BACKGROUND Traumatic hip dislocation in children and adolescents is a rare entity that typically results from high-energy trauma. After closed joint reduction, further treatment depends on the specific pattern of the lesion as identified using cross sectional imaging. The aim of this retrospective analysis was to evaluate relevant side effects after traumatic hip dislocation in children and adolescents in order to examine the need for focused diagnostics. PATIENTS/MATERIAL AND METHODS This retrospective analysis covered 8 adolescents under 18 years suffering isolated traumatic hip joint dislocation between 2001 and 2017. In all patients, closed joint reduction was performed immediately after admission to the emergency room. In order to evaluate the complete extent of the injury, 5 patients received an MRI and 3 patients a CT scan following closed joint reduction. RESULTS Two female and 6 male patients with a median age of 11 (range 5 - 16) years were included. In 2 cases, a free joint body was detected in the posterior joint gap in the posttraumatic CT scan after closed joint reduction. Interposition of the labrum into the joint gap was detected intraoperatively in both cases. In one patient who received posttraumatic MRI, labral interposition into the joint gap was observed after closed reduction. These findings were confirmed intraoperatively. In 4 other patients, no posttraumatic labral lesion was detected in the MRI after closed reduction. The reported side effects included ruptured anterior inferior iliac spine and ruptured femoral head ligament. CONCLUSION MRI is gaining increasing importance following traumatic hip dislocation in children and adolescents. A missing chondral or osteochondral fragment in the CT scan does not exclude a labral lesion or interposition. Therefore, MRI following closed reduction is mandatory in any case.

Abstract
This article describes the operative stabilization of a flail chest due to traumatic serial rib fractures with extensive chest wall deformation and respiratory insufficiency. Initial conservative treatment including systemic and regional pain management and non-invasive positive pressure ventilation did not improve the pain or ventilation. Therefore, a single-port video-assisted thoracoscopic surgery (VATS) assisted internal fixation of the ribs was performed. The thoracoscopy enabled easy repositioning of the ribs and additionally an estimation of intrathoracic injuries.

Abstract
INTRODUCTION Kirschner wire osteosynthesis is considered to be the standard technique for surgical fixation of displaced supracondylar humeral and distal radial fractures in children. The Kirschner wires can be left exposed or buried under the skin. Advantages of the epicutaneous technique are, e. g. the efficiency (cost, effort) and the possibility for wire removal without the necessity of a second anesthesia. On the other hand, there is a concern about higher infection rates as well as traumatization of the children due to externally visible wires. METHODS A web-based survey of members of the DGU, DGOU, DGOOC, and the pediatric traumatology section of the DGU (SKT) was performed to evaluate current treatment concepts in Germany. The pros and cons for each technique were recorded and the need for a clinical study was examined. In addition, a cost analysis was performed for both methods. The results from the literature are summarized and discussed. RESULTS A total of 710 questionnaires were evaluated. The majority of the respondents were trauma surgeons working in a hospital (80%). The buried technique was superior in both fracture groups (supracondylar humeral fractures 73% and distal radius fractures 69%), whereas a relevant difference could be found depending on the profession. The main reason for the subcutaneous technique was anxiety or observed higher infections using the epicutaneous technique. CONCLUSION In Germany, the majority of wires are buried under the skin due to a fear of higher infection rates. In addition, other influencing factors such as pain and traditional approaches play a significant role. With respect to the results in the literature as well as a possible improvement of efficiency and avoidance of a second anesthesia, a multicentric clinical study seems necessary in the future to compare both techniques.

Abstract
Background Current studies demonstrate encouraging short-term results after primary anterior cruciate ligament (ACL) suture anchor repair. However, earlier studies reported deterioration of knee function at 5-year follow-up following good clinical short-term recovery. Therefore, the aim of this study was to evaluate clinical long-term results after primary ACL repair at a minimum 5-year follow-up. Methods In a retrospective study, 13 patients were included between 2009 and 2012. Inclusion criteria were an acute proximal, femoral avulsion tear of the ACL with good tissue quality and sagittal instability in a healthy, demanding patient. Patients suffering proximal tibial fractures, arthrosis, or multiligamentous injuries of the knee were excluded. The ACL was anchored to the footprint by a single 2.9-mm push lock anchor, followed by additional microfracturing. For follow-up, patients were evaluated according to Lysholm score, modified Cincinnati score, and Tegner activity score. Clinical examination was performed using Lachman and pivot-shift testing and range of motion and sagittal stability measurement, using a Rolimeter. Results Mean follow-up was 79 (range 60 to 98) months. One patient was lost to follow-up, and 11 out of 12 patients were examined clinically. Eight patients achieved good subjective and clinical outcome. One patient suffered an early re-tear, and one patient with additional patellar tendon tear and one patient with polyarthritis demonstrated poor subjective and clinical results due to lasting instability. Seven out of 12 patients reached preoperative Tegner activity score postoperatively again. The mean Lysholm score was 85.3 points, mean subjective IKDC score was 87.3 points, and mean modified Cincinnati score was 83.8 points. Rolimeter measurements demonstrated a mean side-to-side difference of 2 (range 1–5) mm. Conclusion In the current study, primary surgical re-fixation of proximal, femoral ACL avulsion tears using single suture anchor repair resulted in good to excellent clinical mid-term outcomes. However, in cases of additional serious damage to extensor structures or systemic rheumatic disease, loss of function and unsatisfying clinical results occurred. Further prospective randomized controlled trials are necessary to confirm the encouraging long-term results of this study.

Abstract
Current recommendations support early surgical decompression and blood pressure augmentation after traumatic spinal cord injury (SCI). Elevated intraspinal pressure (ISP), however, has probably been underestimated in the pathophysiology of SCI. Recent studies provide some evidence that ISP measurements and durotomy may be beneficial for individuals suffering from SCI. Compression of the spinal cord against the meninges in SCI patients causes a "compartment-like" syndrome. In such cases, intentional durotomy with augmentative duroplasty to reduce ISP and improve spinal cord perfusion pressure (SCPP) may be indicated. Prior to performing these procedures routinely, profound knowledge of the spinal meninges is essential. Here, we provide an in-depth review of relevant literature along with neuroanatomical illustrations and imaging correlates.

Abstract
The adequate treatment of severely injured patients is challenging and can only be successfully executed when it starts at the accident site and is continued in all treatment phases including the early rehabilitation phase. Treatment should be performed by an interdisciplinary team guided by a trauma surgeon in order to adequately manage the severe injuries some of which are life-threatening. Treatment of polytrauma patients is a key task of certified trauma centers and must follow standardized guidelines. For a successful therapy of severely injured patients lifetime training at regular intervals in well-established polytrauma concepts is a mandatory requirement.

Abstract
INTRODUCTION Classical fracture classifications (AO/OTA, Schatzker) are commonly used to characterize bicondylar proximal tibial fractures. However, none of these classifications allows for a treatment algorithm. The aim of our study was to use 3D appearance of these fractures in CT imaging to improve the clinical value of the classification. MATERIALS AND METHODS 3D appearance of 81 CT scans of bicondylar proximal tibial fractures were systematically analyzed and were classified in 3 subtypes, based on the fracture lines orientation. The novel classification was compared for reliability and for clinical relevance with AO and Schatzker classification. RESULTS A total of 159 fracture lines were identified which were most frequently oriented in sagittal (89/159), and in coronal (41/159) direction. Based on the orientation of the major fracture lines three fracture types were defined. A special emphasis was drawn to the coronal fracture line of the medial plateau leading to a surgical treatment algorithm. Interobserver reliability was analyzed for all 81 patients resulting in an excellent reliability of К=0.936 for the 3D classification scheme compared to К=0.720 for the AO/OTA, К=0.785 for the Schatzker classification. Correlations with clinical parameters were only observed for the 3D classification. DISCUSSION The presented classification scheme based on the 3D geometry of bicondylar proximal tibial fractures demonstrates a good reliability of clinical relevance.

Abstract
Background Surgical revision concepts for the treatment of aseptic humeral, femoral, and tibial diaphyseal nonunion were evaluated. It was analyzed if the range of time to bone healing was shorter, and if clinical and radiological long-term outcome was better following application of additional recombinant human Bone Morphogenetic Protein-7 (rhBMP-7) compared to no additional rhBMP-7 use. Methods In a retrospective comparative study between 06/2006 and 05/2013, 112 patients diagnosed with aseptic diaphyseal humerus (22 patients), femur (41 patients), and tibia (49 patients) nonunion were treated using internal fixation and bone graft augmentation. For additional stimulation of bone healing, growth factor rhBMP-7 was locally administered in 62 out of 112 patients. Follow-up studies including clinical and radiological assessment were performed at regular intervals as well as after at least one year following nonunion surgery. Results One hundred and two out of 112 (humerus: 19, femur: 37, tibia: 47) nonunion healed within 12 months after revision surgery without any significant differences between the cohort groups. According to the DASH outcome measure for the humerus (p = 0.679), LEFS for the femur (p = 0.251) and the tibia (p = 0.946) as well as to the SF-12 for all entities, no significant differences between the treatment groups were found. Conclusions Aseptic diaphyseal nonunion in humerus, femur, and tibia healed irrespectively of additional rhBMP-7 application. Moreover, the results of this study suggest that successful nonunion healing can be linked to precise surgical concepts using radical removal of nonunion tissue, stable fixation and restoration of axis, length and torsion, rather than to the additional use of signaling proteins. Trial registration This clinical trial was conducted according to ICMJE guidelines as well as to the approval of the National Medical Board (Ethics Committee of the Bavarian State Chamber of Physicians; TRN: 2016-104) and has been retrospectively registered with the German Clinical Trails Register (TRN: DRKS00012652).

Abstract
The so-called transitional fractures describe articular fractures in adolescents with partial closure of the epiphyseal growth plate. This shows a specific stereotype fracture pattern, which can be differentiated into biplane, triplane I and triplane II fractures depending on the involvement of the metaphysis and the number of fragments. The diagnostics and therapy can differ from fractures where the epiphyseal growth plate is still open. The main focus for surgical treatment is the reconstruction of the articular surface whereas relevant growth disturbances no longer need to be feared when the epiphysis has already begun to close.

Abstract
Pyoderma gangrenosum is a rare non-infectious neutrophilic dermatitis, whereas necrotizing fasciitis is a life-threatening bacterial soft tissue infection of the fascia and adjacent skin. As in the case described here after intramedullary nailing, the clinical appearance of both diseases can be similar. Because of the completely different therapeutic approach and a worse outcome in the case of false diagnosis, pyoderma gangrenosum should always be taken into consideration before treating necrotizing fasciitis.

Abstract
UNLABELLED The ability to form biofilm on the surface of implanted devices is often considered the most critical virulence factor possessed by Staphylococcus epidermidis in its role as an opportunistic pathogen in orthopaedic device-related infection (ODRI). Despite this recognition, there is a lack of clinical evidence linking outcome with biofilm forming ability for S. epidermidis ODRIs. We prospectively collected S. epidermidis isolates cultured from patients presenting with ODRI. Antibiotic resistance patterns and biofilm-forming ability was assessed. Patient information was collected and treatment outcome measures were determined after a mean follow-up period of 26 months. The primary outcome measure was cure at follow-up. Univariate logistic regression models were used to determine the influence of biofilm formation and antibiotic resistance on treatment outcome. A total of 124 patients were included in the study, a majority of whom (n = 90) involved infections of the lower extremity. A clear trend emerged in the lower extremity cohort whereby cure rates decreased as the biofilm-forming ability of the isolates increased (84% cure rate for infections caused by non-biofilm formers, 76% cure rate for weak biofilm-formers, and 60% cure rate for the most marked biofilm formers, p = 0.076). Antibiotic resistance did not influence treatment cure rate. Chronic immunosuppression was associated with a statistically significant decrease in cure rate (p = 0.044). CLINICAL SIGNIFICANCE The trend of increasing biofilm-forming ability resulting in lower cure rates for S. epidermidis ODRI indicates biofilm-forming ability of infecting pathogens does influence treatment outcome of infections of the lower extremity. © 2016 Orthopaedic Research Society.

Abstract
INTRODUCTION The thoracic cage is an anatomical entity composed of the upper thoracic spine, the ribs and the sternum. The aims of this study were primarily to analyse the combined injury pattern of thoracic cage injuries and secondarily to evaluate associated injuries, trauma mechanism, and clinical outcome. We hypothesized that the sternal fracture is frequently associated with an unstable fracture of the thoracic spine and that it may be an indicator for unstable thoracic cage injuries. PATIENTS AND METHODS Inclusion criteria for the study were (a) sternal fracture and concomitant thoracic spine fracture, (b) ISS≥16, (c) age under 50 years, (d) presence of a whole body computed-tomography performed at admission of the patient to the hospital. Inclusion criteria for the control group were as follows: (a) thoracic spine fracture without concomitant sternal fracture, (b)-(d) same as study cohort. RESULTS In a 10-year-period, 64 patients treated with a thoracic cage injury met inclusion criteria. 122 patients were included into the control cohort. In patients with a concomitant sternal fracture, a highly unstable fracture (AO/OTA type B or C) of the thoracic spine was detected in 62.5% and therefore, it was significantly more frequent compared to the control group (36.1%). If in patients with a thoracic cage injury sternal fracture and T1-T12 fracture were located in the same segment, a rotationally unstable type C fracture was observed more frequently. The displacement of the sternal fracture did not influence the severity of the concomitant T1-T12 fracture. CONCLUSIONS The concomitant sternal fracture is an indicator for an unstable burst fracture, type B or C fracture of the thoracic spine, which requires surgical stabilization. If sternal and thoracic spine fractures are located in the same segment, a highly rotationally unstable type C fracture has to be expected.

Abstract
PURPOSE The aim of this study was to evaluate a standardized treatment protocol regarding the rate of secondary bone union, complications, and functional outcome. METHODS This study was started as a prospective study in a single Level I Trauma Centre between 2003 and 2012. The study group consisted of 188 patients with the diagnosis of an aseptic tibial shaft nonunion. Exchange nailing was performed following a standardized surgical protocol. Long-term follow-up was analyzed for rate of bone healing and functional outcome. RESULTS Osseous healing was achieved in 182 out of 188 patients (97 %). In 165 out of 188 patients (88 %), bone healing was observed timely and uneventfully after a single exchange nailing procedure. An open approach was necessary in 32 patients (17 %). Twenty-three patients (12 %) required additional therapy such as extracorporeal shock wave therapy. Post-operative complications were observed in seven patients (4 %). Almost all patients demonstrated osseous healing within 12 months, with the majority of osseous healing occurring within six months. A relevant shortening of the fractured tibia was observed in 20 out of 188 patients (11 %). After a median follow-up of 23 months (range 12-45 months), outcome was evaluated using the assessment system of Friedman/Wyman. In summary, 154 out of 188 patients (82 %) had a good functional long-term result. DISCUSSION Reamed intramedullary exchange nailing including correction of axis alignment is a safe and effective treatment of aseptic tibial shaft nonunion with a high rate of bone healing and a good radiological and functional long-term outcome.

Abstract
INTRODUCTION In this cohort study, the surgical revision concept of open compression plating and autologous bone grafting with and without additional application of BMP for treatment of aseptic ulna and/or radius shaft nonunion was evaluated. The purpose was to evaluate the clinical and radiological outcome, and to determine any difference in osseous healing, range of time between revision surgery and bone healing, and postoperative complications between the cohort groups. PATIENTS AND METHODS Between 01/2005 and 03/2015, a prospective, randomised, controlled cohort study was performed in a Level I Trauma Centre. Forty-nine patients were treated with the diagnosis of aseptic diaphyseal ulnar and/or radial shaft nonunion using compression plating and autologous bone grafting. Additional biological augmentation using BMP-2 or BMP-7 was performed in 24 patients. Clinical and radiological follow-up was performed six weeks, three and six months after revision surgery in accordance to the system by Anderson. RESULTS The study group consisted of 38 men and 11 women with a median age of 44 years (range 19-77). Twenty-four out of 49 patients obtained compression plating either with autologous iliac crest bone grafting (11/24 patients) or cancellous bone grafting (13/24 patients) and additional application of BMP-2 (4/24 patients) or BMP-7 (20/24 patients). The remaining 25 patients did not receive any additional application of BMP, but autologous bone grafting. The median follow-up was 15 months (range 6-54 months). Forty-six out of 49 nonunion healed within 12 months after revision surgery with a median time to union of six months. The clinical outcome, as assessed using the system by Anderson, as well as osseous healing, duration of time interval between revision surgery and bone healing, and postoperative complications did not demonstrate significant differences between the cohort groups. DISCUSSION Atrophic/oligotrophic forearm nonunion healed irrespective of additional application of BMP combined with autologous bone grafting. For successful treatment, radical resection of fibrous nonunion tissue and internal compression plate fixation is required with the aim of achieving high degree of rigid stability. Also, correction of angular deformities, restoration of length, and precise axial alignment of the distal radio-ulnar joint are mandatory prerequisites to successfully achieve bone healing.

Abstract
BACKGROUND Osteosynthesis of distal tibia fractures relies on stable fixation of the distal fragment. Modern intramedullary implants provide various fixation options for locking screws. These implants expand the indications for intramedullary nailing of tibia fractures towards more distally located fractures. MATERIAL AND METHODS The most essential options which improve the fixation of the distal fragment include an increase in number, in size and in spacing of the distal locking screws. Further options for nailing of distal tibia fractures include interfragmentary compression and angular stability. Interfragmentary compression considerably increases mechanical stability in axially stable fracture situations. Angular stable fixation of the locking screws has recently become a popular feature in intramedullary nailing; however, the effect of angular stability on the mechanical properties of distal tibia osteosynthesis has been found to be limited. CONCLUSION The initial stability to provide sufficient load bearing capacity appears to be provided by the available locking options. With at least two screws, preferably in crossed configuration and spaced over the largest available distance of the distal fragment, secure and stable fixation can be achieved. Insertion of the locking screws in a free hand technique typically results in jamming of the locking screw with the nail and with cortical bone, providing inherent angular stability of the construct. Angular stable locking features of the nail itself do not appear to improve mechanical stability or to affect healing of distal tibia fractures.

Abstract
Computed tomography (CT) is the method of choice in the diagnosis and classification of odontoid fractures with a sensitivity of more than 99 % and a specificity almost equally as high. In this article we report on four cases where CT-generated motion artefacts exactly mimicked an Anderson type II fracture of the dens axis, initially leading to a wrong diagnosis. Although this seems to be a very rare event, these cases indicate that overlooked CT motion artefacts can lead to severe consequences and attention must be paid to the radiological signs outlined in this report.

Abstract
Charcot spinal arthropathy (CSA) is most likely increasing in patients suffering from consequences of spinal cord injury. We want to highlight initial symptoms, certain risk factors and perioperative complications of this condition. A single center retrospective case series in a specialized Center for Spinal Cord Injuries, BG Trauma Center Murnau, Germany highlighting the potential obstacles in the management of Charcot spine. We describe four female paraplegic patients (mean age: 50.75 years; range: 42-67), who developed Charcot spinal arthropathies. The mean age at the time of the accident was 21.5 years (3-35), the time lag after the accident before CSA was developed and finally diagnosed was on average 29.5 years (17-39) and the mean follow-up period was 39.5 months (6-73). Patient histories, initial symptoms, risk factors as well as the management and postoperative complications are provided. Charcot spine is an important potential sequel of spinal cord injury, which can lead to significant disability and spinal emergencies in affected individuals. More studies are needed to provide better recommendations for spine surgeons. Conservative treatment is an option. Posterior fixation alone does not seem to be sufficient.

Abstract
BACKGROUND The German statutory accident insurance (DGUV) has the statutory mandate to eliminate or to prevent an aggravation of the consequences of accidents by all appropriate means and is based on the principle of rehabilitation before pension. For this, special methods have been developed in recent decades, such as employer's mutual insurance inpatient further treatment (BGSW, Berufsgenossenschaftliche Stationäre Weiterbehandlung) and extended outpatient physiotherapy (EAP, Erweiterte Ambulante Physiotherapie). In 2012 the workplace-related musculoskeletal rehabilitation (ABMR, Arbeitsplatz-bezogene muskuloskelettale Rehabilitation) was added to these complex treatments. SPECIAL REHABILITATION MEASURES For complex injuries and delayed healing these methods approach their limits. The accident clinics of the Association of Clinics in Statutory Accident Insurance (KUV, Klinikverbund der gesetzlichen Unfallversicherung) provide a number of specialized rehabilitation measures in order to ensure an optimal seamless rehabilitation of the severely injured. In addition to complex inpatient rehabilitation (KSR, Komplexe Stationäre Rehabilitation) integrated special rehabilitation procedures, such as neurorehabilitation for severely traumatic brain injured patients and rehabilitation after spinal cord injury and other special rehabilitation methods, such as occupation-oriented rehabilitation (TOR, Tätigkeitsorientierte Rehabilitation) and pain rehabilitation, ensure that the German Society for Trauma Surgery (DGU) phase model of trauma rehabilitation is implemented. This provides an early start in the context of acute treatment as so-called early rehabilitation. After a specialized post-acute rehabilitation, additional therapeutic options are often required. CONCLUSION An appropriate treatment of severely injured patients is important, for example through rehabilitation managers, which must not end with discharge from the rehabilitation hospital. The aim of all efforts is the reintegration into the working and social environment in addition to the best possible quality of life.

Abstract
BACKGROUND CONTEXT Little is known about the incidence of spinal cord injury (SCI) in polytrauma patients. PURPOSE The purpose of this study was to analyze incidence, prognosis, and outcome of SCI in polytrauma patients. STUDY DESIGN/SETTING This is a retrospective multicenter cohort study. PATIENT SAMPLE A total of 57,310 patients of TraumaRegister DGU (2002-2012) of the German Trauma Society were included. Aim of this large multicentre database is a standardized documentation of severely injured patients. OUTCOME MEASURES Outcome measures were mortality and Glasgow Outcome 4Scale. METHODS Inclusion criteria were adult blunt trauma patients (age greater than 16 years) and injury severity score (ISS) greater than 16. The severity of SCI was based on the Abbreviated Injury Scale (AIS), and the outcome of patients was assessed with the Glasgow Outcome Scale (GOS). Factors with an impact on the outcome were analyzed with a logistic regression model. RESULTS Four thousand two hundred eighty five (7.5%) of 57,310 patients sustained SCI. Mean age was 48.9±20.7 years, ISS 28.0±12, and 72.7% were men. Two thousand two hundred twenty two (3.9%) SCIs involved the cervical, 1,388 (2.4%) the thoracic, and 791 (1.4%) the lumbar spine. One hundred fifty-nine (7.2%) cervical spine injuries were associated with transient neurologic deficit (TND) (AIS 3), 612 (27.5%) with an incomplete paraplegia (AIS 4), 1,101 (49.6%) with a complete paraplegia (AIS 5), and 350 (15.8%) with a complete lesion above C3 (AIS 6). Lesions of the thoracic spine showed in 93 (6.7%) of the 1,388 lesions a TND (AIS 3), in 332 (23.9%) an incomplete paraplegia (AIS 4), and in 963 (69.4%) a complete lesion (AIS 5). In the lumbar region, lesions were distributed as follows: TND (AIS 3) 145 (18.3%), incomplete paraplegia (AIS 4) 305 (38.6%), and complete lesion 341 (43.1%). Sepsis and multiorgan failure were found more often in patients with AIS 5/6 lesions (p<.001). The hospital length of stay in SCIs was significantly longer. Most of the patients (85.8%) with SCI were treated in Level I trauma centers. Spinal cord injuries had a minor impact in the mortality. Only AIS 6 injuries resulted in a significantly higher mortality (64.6%). Adjusted logistic regression analysis (target variable: GOS 4 or 5, good outcome) showed that the following factors were significantly associated with an unfavorable outcome (p≤.02): AIS greater than or equal to 4, age greater than or equal to 60 years, resuscitation, severe head injury, shock on scene, and severity of injury (ISS per point). CONCLUSIONS Spinal cord injury with a neurologic deficit could be found in every 13th patient with polytrauma. Over half of the patients with SCI suffer from complete cord lesion. In polytrauma patients, SCI only has a limited influence on the mortality, with exception of AIS 6 lesions. Complications such as multiorgan failure or sepsis and extended hospital length of stay are more frequent in SCI.

Abstract
Background The issue of patient volume related to trauma outcomes is still under debate. This study aimed to investigate the relationship between number of severely injured patients treated and mortality in German trauma hospitals. Methods This was a retrospective analysis of the TraumaRegister DGU® (2009–2013). The inclusion criteria were patients in Germany with a severe trauma injury (defined as Injury Severity Score (ISS) of at least 16), and with data available for calculation of Revised Injury Severity Classification (RISC) II score. Patients transferred early were excluded. Outcome analysis (observed versus expected mortality obtained by RISC‐II score) was performed by logistic regression. Results A total of 39 289 patients were included. Mean(s.d.) age was 49·9(21·8) years, 27 824 (71·3 per cent) were male, mean(s.d.) ISS was 27·2(11·6) and 10 826 (29·2 per cent) had a Glasgow Coma Scale score below 8. Of 587 hospitals, 98 were level I, 235 level II and 254 level III trauma centres. There was no significant difference between observed and expected mortality in volume subgroups with 40–59, 60–79 or 80–99 patients treated per year. In the subgroups with 1–19 and 20–39 patients per year, the observed mortality was significantly greater than the predicted mortality (P < 0·050). High‐volume hospitals had an absolute difference between observed and predicted mortality, suggesting a survival benefit of about 1 per cent compared with low‐volume hospitals. Adjusted logistic regression analysis (including hospital level) identified patient volume as an independent positive predictor of survival (odds ratio 1·001 per patient per year; P = 0·038). Conclusion The hospital volume of severely injured patients was identified as an independent predictor of survival. A clear cut‐off value for volume could not be established, but at least 40 patients per year per hospital appeared beneficial for survival. No clear volume cut‐off

Abstract
BACKGROUND The dislocated posterolateral fragment of the distal tibia is considered as a key fragment for the successful reduction of comminuted ankle fractures. The reduction of this fragment can either be achieved indirectly by joint reduction using the technique of closed anterior-posterior screw fixation, or directly using the open posterolateral approach followed by plate fixation. The aim of this study was to compare the outcome after stabilization of the dislocated posterolateral tibia fragment using either closed reduction and screw fixation, or open reduction and plate fixation via the posterolateral approach in complex ankle fractures. PATIENTS/MATERIAL AND METHODS In a prospective study between 01/2010 and 12/2012, all mono-injured patients with closed ankle fractures and dislocated posterolateral tibia fragments were assessed 12 months after osteosynthesis. Parameters included: size of the posterolateral tibia fragment relative to the tibial joint surface (CT scan, in %) as an indicator of injury severity, unreduced area of tibial joint surface postoperatively, treatment outcome assessed by using the "Ankle Fracture Scoring System" (AFSS), as well as epidemiological data and duration of the initial hospital treatment. RESULTS In 11 patients (10 female, 1 male; age 51.6 ± 2.6 years [mean ± SEM], size of tibia fragment 42.1 ± 2.5 %) the fragment fixation was performed using a posterolateral approach. Impaired postoperative wound healing occurred in 2 patients of this group. In the comparison group, 12 patients were treated using the technique of closed anterior-posterior screw fixation (10 female, 2 male; age 59.5 ± 6.7 years, size of tibia fragment 45.9 ± 1.5 %). One patient of this group suffered an incomplete lesion of the superficial peroneal nerve. Radiological evaluation of the joint surface using CT scan imaging demonstrated significantly less dislocation of the tibial joint surface following the open posterolateral approach (0.60 ± 0.20 mm) compared to the closed anterior-posterior screw fixation (1.03 ± 0.08 mm; p < 0.05). Assessment of the treatment outcome using the AFSS demonstrated a significantly higher score of 97.4 ± 6.4 in the group with a posterolateral approach compared to a score of 74.4 ± 12.1 (p < 0.05) in the group with an anterior-posterior screw fixation. CONCLUSION In comparison to the anterior-posterior screw fixation, open reduction and fixation of the dislocated, posterolateral key fragment of the distal tibia using a posterolateral approach resulted in a more accurate fracture reduction and significantly better functional outcome 12 months after surgery. In addition, no increased rate of postoperative complications, or extended hospital stay was observed but there was less severe post-traumatic joint arthritis. The results of this study suggest that in complex ankle factures the open fixation of the dislocated posterolateral fragment is recommended as an alternative surgical procedure and may be beneficial for both clinical and radiological long-term outcomes.

Abstract
INTRODUCTION Mechanical breakage of cephalomedullary nail osteosynthesis is a rare complication attributed to delayed fracture union or nonunion. This study presents a series of cases of breakage and secondary lag screw dislocation after cephalomedullary nailing. The aim of this study was to identify factors that contribute to cephalomedullary nail breakage. MATERIALS AND METHODS In a retrospective case series review between 02/2005 and 12/2013, we analyzed 453 patients with trochanteric and subtrochanteric fracture who had been treated by cephalomedullary nailing. Fractures were classified according to AO/OTA classification. 13 patients with cephalomedullary nail breakage were included (failure rate 2.9 %). RESULTS Seven patients were women, and six men with a mean age of 72 years (range 35-94). Implant breakage occurred 6 months postoperatively (range 1-19 months). In ten cases, breakage was secondary to delayed or nonunion, which was thought to be mainly due to insufficient reduction of the fracture, and in two cases due to loss of the lag screw because of missing set screw. In one case, breakage was apparent during elective metal removal following complete fracture healing. Short-term outcome was evaluated 6 months after operative revision using Harris hip score in 11 out of 13 patients showing a mean score of 84 %. Complete radiological fracture healing has been found in 11 patients available for follow-up within 6 months after revision surgery. DISCUSSION Breakage of cephalomedullary nail osteosynthesis of trochanteric fractures is a severe complication. The results of our study demonstrate that revision surgery provides good clinical and radiological short-term results. Predominately, failures of trochanteric fractures are related to lack of surgeon performance. Therefore, application of the implant requires accurate preoperative planning, advanced surgical experience to evaluate the patient and the fracture classification, and precise surgical technique including attention to detail and anatomical reduction of the fracture fragments.

Abstract
Background Concurrent ipsilateral fractures of the proximal and shaft of the femur are rare complex fracture combinations. In this prospective cohort study, we evaluated clinical and radiological long-term results after operative treatment using several surgical strategies: the so-called “rendezvous” surgical technique, e.g., the combination of retrograde intramedullary nailing and dynamic hip screw (DHS) osteosynthesis, or the all-in-one device technique, e.g., long cephalomedullary nail, compared with two non-overlapping implants (e.g., conventional technique). Methods In a 10-year-period from 2004 to 2013, we treated 65 patients with complex ipsilateral multi-level femoral fractures. Median age was 45 years (range 19–90 years). Fractures were classified according to the AO/OTA classification. Four patients died during intensive care unit treatment due to multi-organ failure prior to definitive osteosynthesis. Clinical long-term outcome using the functional system of Friedman/Wyman as well as radiological outcome was evaluated 2 years after trauma (range 13–42 months). Results All-in-one device was used in 36 patients, “rendezvous” technique in 9 patients, and the conventional technique in the remaining 16 patients. Two years after trauma, complete fracture healing was found in 57 out of 61 patients (“rendezvous”: 9, all-in-one device: 33, conventional: 15; p-value: 0.66). There was no significant difference regarding the complication rate in the cohort groups (“rendezvous”: 3, all-in-one device: 13, conventional: 5; p-value: 0.94). Using the functional assessment system of Friedman/Wyman 2 years after trauma, a good clinical result was found in 77.7% in the “rendezvous” group, in 77.8% in the all-in-one device group, and in 75% in the conventional group. Conclusion The indication for operative stabilization of ipsilateral multi-level femoral fractures is considered an urgent and emergency procedure. Based on the successful long-term results of this study, we prefer the “rendezvous” technique with fracture stabilization from distally to proximally. Both fracture components require stable fixation. It is advisable to stabilize the shaft fracture primarily using external fixation (damage control orthopedics) and the proximal femoral fracture using early definitive internal fixation. In a second and staged operation, the external fixator is removed and the shaft fracture is stabilized using retrograde nail osteosynthesis with overlapping of the DHS and nail implants.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVES This study was implemented to detect risk factors for the developing of heterotopic ossifications (HOs) in spinal cord injury (SCI) patients. SETTING This study was conducted in Murnau, Germany. METHODS All patients from 2008-2012 with acute SCI were routinely examined by ultrasound of the hips every 2 weeks. The sub group of SCI patients suffering of HO of the hips were extracted and the incidence of developing an HO was calculated. Parameters like age, level of injury, ASIA Impairment Scale (AIS), duration time of accident until diagnosis of HO, Brooker stage, localization of HO (magnetic resonance imaging (MRI)) and symptoms like thrombosis, emboli, decrease of range of motion (ROM), dermal symptoms, swelling, increase in D-Dimere level, were evaluated. Also accompanying injuries of the brain, lung and extremities were recorded. RESULTS From January 2008 until January 2012, 575 patients with an acute and traumatic SCI were treated in our Department. During this period 32 HOs were detected in the muscles surrounding the hip. In 10 cases a single side and in 22 cases both sides were affected. A total of 26 patients were detected showing up a Brooker 0, two patients Brooker 1, and five patients a Brooker stage >2. The adductor muscles showed an edema in 19 cases and the quadriceps muscles were affected in 15 cases. 26% of all SCI patients showed AIS A status, but in patients who developed HO, 64% have had an AIS A status. 19% of patients with a HO were AIS B and 9.5% showed an AIS C and D. Regarding the level of injury the distribution of patients suffering of HO was comparable to the distribution of SCI patients without HO. In mean HO were detected 9 weeks after SCI and no new HO were found after the 22nd (n=1) week of injury. Clinical symptoms such as swelling, pain, redness or decrease in ROM or increase in D-Dimere levels were seen in 24 cases. Accompanying injuries like brain injury and lung contusions were found in 83% of patients developing HO. The incidence of thrombosis was comparable to SCI patients without HO. One patient with no accompanying injuries or clinical symptoms was detected by routinely performed ultrasound. CONCLUSIONS The risk of developing HO in patients with traumatic SCI is 5.5% but increases when accompanying injuries of the brain and lung occur. Patients with a neurological status of AIS A must also be quoted as risk patients. When considering the described risk factors and clinical symptoms, 96% of all HO can be detected.

Abstract
Background Scapula fractures with injuries of the Superior Shoulder Suspensory Complex are often referred to as floating shoulders. However, present studies do not allow comparative evidence on indication for surgical treatment mostly due to the lack of precise definitions and comparable classifications. The aim of this study was to retrospectively analyze common types of complex shoulder injuries and develop a feasible classification allowing a therapeutic algorithm. Methods The study group consisted of 107 patients with scapula fractures combined with ipsilateral injuries of the shoulder girdle treated in a single trauma center between 2003 and 2010. Three-dimensional computed tomography was analyzed for dislocation and instability and assigned to subgroups of a defined classification system. Clinical data was acquired from a previously established database of all patients treated for the diagnosis of a scapula fracture. Results Fifty-seven of 107 (53.3%) complex scapula fractures were non-displaced and stable representing Type A fractures. Depending on the fracture pattern, three subgroups were defined. Treatment of Type A injuries should be non-operative. Displaced fractures of the scapula with a stable shoulder girdle were considered Type B injuries and represented 18.7% of all fractures. Thirty fractures (28%) with an unstable shoulder girdle were classified as Type C injuries. Again, subgroups with common injury patterns were identified. For both groups, operative treatment is recommended. Conclusions The described classification system is a proposal able to categorize complex shoulder injuries and allows a comparison of injury patterns in further studies.

Abstract
BACKGROUND The aim of this study was to evaluate a standardized method of treatment of femoral nonunion of the isthmal femur excluding non-united metaphyseal fractures. METHODS Between 2003 and 2010, 72 consecutive patients with nonunion of the femoral shaft were operated using a standardized protocol in our trauma department and followed up for successful union and functional result. RESULTS Osseous healing was observed in 71 patients (98%). Only one patient was lacking bone healing following a time period of 24 months after the first exchange nailing and 5 months after the second exchange nailing. In 59 patients (82%), uneventful and timely bone healing after exchange nailing was detected. In 18% of patients (n = 13), delayed bone healing was observed and required additional therapy. In the majority of patients (61%), bone healing occurred within the first 2 to 5 months, only 18% of patients' duration of bone healing exceeded 8 months. In 62 patients (86%), no relevant or clinically apparent leg-length discrepancy prior to and after exchange nailing was detected as well as no significant axis deviation or malrotation. Functional studies including simple clinical gait and standing analysis, return to activities of daily life, return to sports activities, and return to work were all reached on a satisfying level. DISCUSSION Reamed intramedullary exchange nailing as described in this study is the treatment of choice for aseptic femoral shaft nonunion with a high rate of bone healing and a low rate of complications including length discrepancy or malrotation and a good functional outcome.

Abstract
Consequences of accidents are found not only in physical but also in psychological and social areas. The quality of life of severely injured patients is significantly reduced compared with the normal population even years after the trauma. Subjective experiences of severely injured patients during and after hospitalization have a major impact on the subsequent quality of life. Knowledge of these factors is essential for the planning, organization and implementation of rehabilitation after severe injury. The phase model of rehabilitation after trauma requires early initiation of therapy even during acute treatment as so-called early rehabilitation. After a specialized post-acute rehabilitation additional therapeutic options are often required. Besides pain management the focus lies especially in work-related rehabilitation and psychological support which is also decisive for the success of rehabilitation of accident victims. For severely injured patients it is important to provide sufficient support, e.g. through a case manager which does not end with discharge from the rehabilitation facility. The aim of all efforts is reintegration into the working and social environment and the best possible quality of life.

Abstract
Objectives: The purpose of this study was to determine the effect of botulinum toxin injections for the treatment of spasticity after traumatic spinal cord injury. Methods: 9 patients were included in this prospective designed study, with a follow-up of at least 2 years. All patients suffered from a massive spasticity after traumatic spinal cord lesion. Conservative treatment options did not show satisfying results. All patients were injected a maximal dose of 2,000 units of botulinum toxin A in no more than 6 skeletal muscle groups. Clinical control examinations were performed after 2 weeks and after at least 2 years. Results: 6 patients reported a good or very good result. One patient offered increasing difficulty in walking for a short time after injection. 2 patients showed no beneficial effects. One patient experienced a modest temporary general weakness for 3 days. After 2 years, 3 patients showed improved function with persistent reduction of spasticity. In the other cases, the beneficial effect lasted for an average of 9 months. Conclusion: Botulinum toxin A injection seems to be an effective complementary therapy option in the treatment of spasticity of paraplegic patients with complete deficit of their motor function (ASIA A and B) and a spastic distribution pattern, effecting only a limited number of muscle groups. Caution has to be recommended for incomplete paretic patients, who are able to walk.
