Abstract
OBJECTIVE Surgical treatment of intra-articular calcaneus fractures via a minimally invasive approach. INDICATIONS Intra-articular dislocated calcaneus fractures. CONTRAINDICATIONS Fracture older than 14 days; poor soft tissue quality in the surgical area. SURGICAL TECHNIQUE Patient in lateral position. Identifying the anatomic landmarks. Incision (3-5 cm) from the tip of the fibula to metatarsal IV. Preparation through the subcutis. Retraction of the peroneal tendons. Preparation of the lateral calcaneal wall and later plate position via raspatory. Placement of a Schanz screw in the calcaneal tuberosity from lateral or posterior as a reduction aid for restoring of the calcaneal length and reduction of the hindfoot varus. Reduction of the sustentaculum fragment with the help of fluoroscopy from lateral. Elevation of the subtalar articular surface. Positioning of the calcaneal plate and fixation of the sustentaculum fragment by placing a cannulated screw through the long hole. Afterwards, definite internal fixation of the reduction with locking screws. Completion of the operation with final X‑rays and, if available, an intraoperative computed tomography. Wound closure with closing of the peroneal sheath. POSTOPERATIVE MANAGEMENT Lower leg-foot orthoses. Mobilization with partial weight-bearing of the injured foot with 15 kg for 6-8 weeks; subsequently increased load bearing. RESULTS Due to the smaller incision and the associated lower soft tissue trauma, the risk of wound healing complications can be reduced. Radiographic and functional outcomes are comparable to the outcomes of calcaneal fractures treated via the extended lateral approach.

Abstract
Background and Objective Ankle fractures occur frequently in patients throughout all ages. Due to the many pitfalls associated with their treatment, complex ankle and especially tibial pilon fractures remain a challenge for surgeons. As there is still need for improvement in treating complex ankle fractures and treatment options are steadily increasing this review aims to summarize current practice and aims to highlight current developments by reviewing the literature. Methods We conducted a thorough search of PubMed database in December 2022 to identify relevant articles on complex ankle and tibial pilon fractures. Articles in English and German were included in this study. Key Contents and Findings Complication rates, especially wound infection are still high, emphasizing the need for careful preoperative planning. Soft tissue management is crucial to reduce complication rates and will often dictate the treatment plan utilized. Open reduction and internal fixation (ORIF) remains the treatment of choice. Nevertheless, in select cases alternative methods such as external fixation, tibiotalocalcaneal nailing or conservative treatment need to be considered as well. Furthermore, additional treatment options such as arthroscopically assisted surgery might help to improve functional outcome after complex ankle fractures. The incidence of complex ankle fractures in geriatric patients keeps rising with our aging population. This group of patients demands particular care and further high-quality studies are needed to warrant best results. Conclusions However, more randomized controlled trials are need in order to enhance evidence of newly developed treatment options.

Abstract
BACKGROUND Patella fractures are relatively rare fractures and only little is known about the postoperative return to sports after patella fractures. METHODS This retrospective study presents information on functional outcome after operative treatment of patella fractures as well as time until return to sports and patients' complaints after open-reduction internal-fixation (ORIF) of patella fractures. RESULTS Overall, 39 patients after ORIF of patella fractures were evaluated at our Level-I trauma center with a mean follow-up of 42 months. The mean time until return to sports was 7 ± 3.9 months. No significant difference was found for functional outcome with respect to body mass index (BMI) or age. Fracture consolidation was accomplished after a mean of 6.9 ± 2.9 months besides a relatively low complication rate of 5.1% (n = 2). CONCLUSION The results demonstrate a high return to sports rate of 90.3%. However, only 51.6% were able to perform sports on their pre-injury level or above. Trial Registration The study was retrospectively registered at DRKS (No: DRKS00031146).

Abstract
Driven by the aging population, the proximal femoral fracture is a rising fracture entity, challenging trauma surgeons as well as the German healthcare system as a whole. The rising average age of the population is accompanied by a rising BMI in the German population, resulting in longer operation times, longer average length of stay (ALOS) as well as more postoperative complications.The aim of this study was to demonstrate the economic correlation between body mass index and hospital costs. The retrospective analysis of 950 patient cases suffering from a proximal femoral fracture resulted in the finding of rising treatment costs being positively associated with rising BMI due to longer operation times and longer length of hospitalization (10,452 €, 11,505 €, 12,085 € and 13,681 € for patients with BMI < 18.5 kg/m2, BMI = 18.5-24.9 kg/m2, BMI = 25.0-29.9 kg/m2 and BMI ≥ 30.0 kg/m2, respectively).

Abstract
Trimalleolar ankle fractures show a bimodal age distribution, affecting younger men and older women. Postmenopausal women often exhibit low bone mineral density, which contributes to a higher prevalence of osteoporotic-related fractures. The primary goal of this study was to analyse the association of patient characteristics with the cortical bone thickness of the distal tibia (CBTT) in trimalleolar ankle fractures. METHODS A total of 193 patients with a trimalleolar ankle fracture treated between 2011 and 2020 were included. Patient registries were reviewed regarding demographics, mechanism, and type of injury. The CBTT was assessed in radiographs and CT images. The FRAX score was calculated to estimate the probability for an osteoporotic fracture. A multivariable regression model was calculated to identify independent variables affecting the cortical bone thickness of the distal tibia. RESULTS Patients older than 55 years were 4.22 (95% CI: 2.12; 8.38) times more likely to be female. In the multivariable regression analysis, female sex (β -0.508, 95% CI: -0.739; -0.278, p < 0.001) and a higher age (β -0.009, 95% CI: -0.149; -0.003, p = 0.002) were independent variables associated with a lower CBTT. Patients with a CBTT < 3.5 mm had a higher 10-year probability for a major osteoporotic fracture (12% vs. 7.75%; p = 0.001). CONCLUSIONS The assessment of the peripheral bone quality in routine computed tomography demonstrated that higher age and female sex are significantly associated with reduced cortical bone thickness of the distal tibia. Patients with a lower CBTT showed a higher probability for a subsequent osteoporotic fracture. In female patients with reduced distal tibial bone quality and associated risk factors, an osteoporosis assessment should be evaluated.

Abstract
Purpose Different classification systems have been developed for ankle fractures. In recent years, the posterior malleolus has gained in importance and led to computed tomography (CT)-based classification systems. The aim of the study was to analyse their reliability, fracture patterns and influence on treatment strategy. Methods Patients with a trimalleolar ankle fracture treated between 2011 and 2020 with preoperative radiographs and CT images were included. The blinded images were independently classified by three reviewers according to the AO/OTA, Herscovici, Bartoníček, Mason and Haraguchi classifications. The interobserver reliability was calculated by Fleiss' kappa (κ). CT images were analysed to determine the dimensions of the posterior malleolus fragments. Patient registries were reviewed regarding the treatment data. Results A total of 193 patients were included. The AO/OTA classification showed almost perfect inter- and intraobserver reliability (Fleiss’ κ = 0.86, 95% CI 0.82–0.90). Regarding the posterior malleolus, the Bartoníček classification demonstrated the highest reliability (Fleiss’ κ = 0.78, 95% CI 0.73–0.83). The Herscovici classification only reached moderate reliability for medial malleolus fractures (Fleiss' κ = 0.59, 95% CI 0.54–0.65). There was a trend towards direct fixation of the posterior malleolus in the last 3 years of the observation period (OR: 2.49, 95% CI 1.03–5.99). Conclusion In trimalleolar ankle fractures, the AO/OTA classification is a reliable system to characterize the type of fracture, but it fails to provide solid information about the posterior malleolus. Nowadays, treatment recommendations for trimalleolar ankle fractures focus on the configuration of the posterior malleolus; therefore, the results of this study advocate the use of the Bartoníček classification as a reliable tool to guide treatment.

Abstract
Tibial pilon fractures were first described by Étienne Destot in 1911. He used the French word “pilon” (i.e., pestle), to describe the mechanical function of the distal tibia in the ankle joint. This term has further been used to portray the mechanism involved in tibial pilon fractures in which the distal tibia acts as a pestle with heavy axial forces over the talus basically causing the tibia to burst. Many different classification systems exist so far, with the AO Classification being the most commonly used classification in the clinical setting. Especially Type C fractures are extremely difficult to manage as the high energy involved in developing this type of injury frequently damages the soft tissue surrounding the fracture zone severely. Therefore, long -term outcome is often poor and correct initial management crucial. In the early years of this century treatment has evolved to a two–staged protocol, which nowadays is the gold standard of care. Additional methods of treating the soft tissue envelope are currently being investigated and have shown promising results for the future. The aim of this review is therefore to summarize protocols in managing these difficult fractures, review the literature on recent developments and therefore give surgeons a better understanding and ability to handle tibial pilon fractures.

Abstract
INTRODUCTION Surgical treatment of complex humeral head fractures in the elderly is challenging due to osteoporotic bone, comorbidities and reduced compliance. The treatment strategy (reconstruction versus replacement) should allow for a functional aftercare and result in a high patient satisfaction. Major complications leading to surgical revision are crucial and should be avoided. The purpose of this study was to analyse the major complication rate leading to surgical revision and the patient-based outcome in complex humeral head fractures of the elderly population treated either using locking plate fixation (LCP) or reversed total shoulder arthroplasty (rTSA). MATERIALS AND METHODS All patients older than 65 years surgically treated due to a four-part fracture of the proximal humerus between 2003 and 2015 were enrolled in our retrospective study. Major complications and revision rates were recorded and functional outcome was assessed using the Munich Shoulder Questionnaire (MSQ) allowing for qualitative self-assessment of the Shoulder Pain and Disability Index (SPADI), of the Disability of the Arm, Shoulder and Hand (DASH) score and of the Constant Score. RESULTS A cohort of 103 patients with a mean age of 73.4 ± 6.2 years suffering from four-part fractures of the humeral head were enrolled. 63 patients were treated using the LCP fixation compared to 40 rTSAs. There were no significant differences in the patient-reported functional outcome. The revision rate was significantly higher in the LCP group (10/63; 15.9%) compared to the rTSA group (1/40; 2.5%). Reasons for revision were avascular head necrosis, cut-out of screws, secondary dislocation of the greater tuberosity and hypersensitivity to metal. CONCLUSIONS Reversed total shoulder arthroplasty and locking plate fixation are both established surgical procedures for the management of complex proximal humerus fractures in the elderly leading to similar functional results. However the revision rate in the rTSA group was significantly lower. Primary rTSA should, therefore, be favoured in multimorbid elderly patients with an increased complication risk to avoid repeated anaesthesia.

Abstract
BACKGROUND Elective implant removal (IR) accounts for up to 30% of all orthopaedic surgeries. While there is general acceptance about the need of implant removal for obvious reasons, such as infections or implant failure, little is known about the beneficial aspects in cases of minor reasons such as patients' wish for IR. Therefore, we initiated this study to define patients' benefit of elective implant removal following plate osteosynthesis of displaced clavicle fractures. PATIENTS AND METHODS Prospective evaluation of patients was conducted before implant removal and 6 weeks postoperative. Subjective and objective criteria included pain rating on a visual analogue scale (VAS) and active range of motion (ROM) pre- and 6 weeks postoperative. Functional scoring included Constant-Murley Score, DASH (Disabilities of Arm, Shoulder and Hand Score), MSQ (Munich Shoulder Questionnaire) and SPADI (Shoulder Pain and Disability Index). RESULTS 37 patients were prospectively enrolled in this study and implant removal was performed after 16 ± 6.1 months. No re-fractures nor other complications were detected during routine follow up. Functional outcome increased through all scores (Constant score 73.3 ± 14.6 preoperative to 87.4 ± 12.0 postoperative (p = 0.000), MSQ 85.0 ± 7.3 preoperative to 91.8 ± 9.0 postoperative (p = 0.005), DASH Score 7.4 ± 8.2 preoperative to 5.7 ± 9.5 postoperative (p = 0.414), SPADI 93.4 ± 6.6 preoperative to 94.0 ± 10.1 postoperative (p = 0.734). CONCLUSIONS Discomfort during daily activities or performing sports as well as limited range of motion were the main reasons for patients' wish for implant removal. We found increased functional outcome parameters and decreased irritation after implant removal. Therefore we suggest implant removal in case of patients' wish and completed fracture consolidation.

Abstract
Background Metatarsal fractures are common skeletal injuries of the lower extremity in adults. The majority involves the proximal fifth metatarsal bone. In the current literature, there still exists controversy regarding treatment recommendations for the different fracture entities. Methods All patients suffering from single fractures to the proximal fifth metatarsal bone between 2003 and 2015 were enrolled in this retrospective analysis. Only patients with a minimum follow-up of 12 months were included. The fractures were classified according to Lawrence and Botte (L&B). Data were collected via patient registry, radiographs and a standardized questionnaire (Foot and Ankle Outcome Score = FOAS). For outcome analysis, the nonparametric Mann–Whitney U test was performed and Spearman’s rank correlation coefficient calculated. Results In total, the functional outcomes of 103 patients suffering from fractures to the proximal fifth metatarsal bone were analyzed. L&B type I fractures (n = 13) had a FAOS score of 91 ± 23, L&B type II (n = 67) presented a score of 91 ± 15 and L&B type III (n = 23) a score of 93 ± 11. Surgically treated patients with an L&B type II fracture had no statistically significant better functional outcome in comparison to conservative management (p = 0.89). Operatively treated L&B type III fractures tended to have a better functional score (p = 0.16). The follow-up time was 58 (min: 15; max: 164) months. Conclusions Overall, the functional outcome following fractures to the proximal fifth metatarsal bone is satisfactory. Conservatively treated L&B type II fractures showed an equivalent functional outcome compared to surgical management. Patients with an L&B type III fracture mainly were treated surgically, but difference in FAOS score did not reach level of significance.

Abstract
Hintergrund Sprunggelenk- und Fußverletzungen gehören zu den häufigsten Krankheitsbildern in der Traumatologie. Ziel dieser Studie war es, die demografischen Veränderungen von Patienten mit Fuß- und Sprunggelenkverletzungen, das zeitliche Auftreten und die Entwicklung über die Jahre in einer Notaufnahme zu untersuchen. Material und Methoden Retrospektive Datenauswertung von Patienten, welche aufgrund einer Fuß- und Sprunggelenkverletzung in der Notaufnahme im Zeitraum von 2010 bis 2017 behandelt wurden. Die Patienten wurden mittels ICD-Codes identifiziert und die demografischen Veränderungen, das zeitliche Auftreten und die Entwicklung über die Jahre analysiert. Mittels Quantil-Quantil-Diagramm wurden kontinuierliche Variablen auf Normalverteilung getestet und, falls zutreffend, mittels t‑Test oder nichtparametrischem Mann-Whitney-U-Test auf Signifikanz überprüft. Ergebnisse Insgesamt wurden 6581 Fuß- und Sprunggelenkverletzungen in die Analyse eingeschlossen. Das mittlere Alter von Patienten mit einer Fußfraktur war 39 ± 17,4 Jahre und mit einer Sprunggelenkfraktur 47 ± 19,2 Jahre (p < 0,001). Ligamentäre Verletzungen des Sprunggelenks traten insbesondere bei jüngeren Patienten in den Sommermonaten auf. Die Altersverteilung bei Sprunggelenkfrakturen zeigte für Männer einen Häufigkeitsgipfel zwischen dem 30. und 39. Lebensjahr und bei Frauen ein vermehrtes Auftreten ab dem 50. Lebensjahr. In der Altersgruppe zwischen 65 und 75 Jahren stellten Trimalleolarfrakturen die zweithäufigste Sprunggelenkfraktur dar. Frakturen des Fußes betrafen am häufigsten Patienten im Alter von 20 bis 29 Jahren, wobei bei Frauen ein 2. Häufigkeitsgipfel zwischen dem 50. und 59. Lebensjahr zu beobachten war. Schlussfolgerung Ligamentäre Verletzungen des Sprunggelenks sind häufige Krankheitsbilder in der Notaufnahme und betreffen v. a. jüngere Patienten. Sprunggelenkfrakturen zeigten für Frauen eine bimodale Altersverteilung, und insbesondere Bi- und Trimalleolarfrakturen waren vermehrt bei Frauen ab dem 65. Lebensjahr zu beobachten. Aufgrund der erhöhten Prävalenz von Fuß- und Sprunggelenkfrakturen bei älteren Frauen sollte in diesem Patientenkollektiv eine weitere Osteoporoseabklärung veranlasst werden.

Abstract
A trimalleolar ankle fracture is considered unstable and treatment is generally performed operatively. Computed tomography is important for the operative planning by providing an elaborated view of the posterior malleolus. Trimalleolar ankle fractures have a rising incidence in the last decade with up to 40 per 100,000 people per year. With a growing number of elderly patients, trimalleolar ankle injuries will become more relevant in the form of fragility fractures, posing a particular challenge for trauma surgeons. In patients with osteoporotic trimalleolar ankle fractures and relevant concomitant conditions, further evidence is awaited to specify indications for open reduction and internal fixation or primary transfixation of the ankle joint. In younger, more demanding patients, arthroscopic-assisted surgery might improve the outcome, but future research is required to identify patients who will benefit from assisted surgical care. This review considers current scientific findings regarding all three malleoli to understand the complexity of trimalleolar ankle injuries and provide the reader with an overview of treatment strategies and research, as well as future perspectives.

Abstract
BACKGROUND Management of talar fractures remains to be one of the most challenging aspects in trauma surgery. Unfortunately, the evidence regarding the correct treatment of these fractures is mainly based on retrospective case series, while studies assessing the patient-reported outcome are rare. Therefore, the aim of this trial was to analyze the patient reported outcome in context of trauma mechanism and concomitant injuries following operative treatment of talar fractures. METHODS A retrospective outcome study of patients with operatively treated talar fractures between 2003 and 2015 was conducted. The fractures were classified according to AO-/Hawkins classification system and to the Marti-Weber classification. Data was collected via patient registry, radiographs and a validated patient-reported outcome measure (PROM) for foot and ankle pathologies (Foot and Ankle Outcome Score = FOAS). An analysis regarding the functional outcome, concomitant injury and timing of surgery using the nonparametric Mann-Whitney U test and Spearman`s rank correlation was performed. RESULTS In total the functional outcome of 32 patients suffering from fractures to the talus were analyzed. The median age of the study cohort was 35±12.2 years, including 9 female (28 %) and 23 male (72 %) patients. The median FAOS score was 72±22.7 (range 13-94). Patients with an isolated talar fracture had an FAOS of 87±20 and with concomitant injury a score of 60±23.4 (p = 0.016). Patients with a closed talar fracture without emergency operation due to dislocation or polytrauma, showed no correlation between timing of surgery and FAOS (r= -0.17, p = 0.43). 10 % of the patients developed an avascular necrosis and 25 % showed signs of a posttraumatic arthritis. The follow-up time was 41 months (range: 16-145). CONCLUSIONS Talar fractures were typically caused by high-energy trauma often associated with additional injuries of the lower extremity. The majority of the patients showed a fair to poor functional long-term outcome. Concomitant injuries of the lower extremity led to a lower FAOS. In closed talar fractures without the necessity of an emergency surgical intervention, time to surgery did not influence the patient reported outcome. Relating to the presented data, delayed surgery after soft tissue consolidation was not associated with a higher risk of developing an avascular necrosis.

Abstract
Background: Fractures of the calcaneus are severe injuries of the hindfoot, mostly resulting from high-energy axial loads, which still present enormous challenges to modern trauma surgery. Possible variables influencing the outcome are the type of fracture, age, and quality of fracture reduction. These might also be factors affecting the self-reported patient outcome, but large studies are still lacking. Therefore, the aim of this study was to analyze the patient-reported outcome of calcaneal fractures following operative and conservative treatment. Methods: All patients suffering from calcaneal fractures between 2002 and 2015 were enrolled in this retrospective analysis. The calcaneal fractures were classified according to Sanders and the AO classification system. For further analysis, two groups were formed: group I involved complex intra-articular fractures defined by the involvement of the posterior calcaneal facet, while group II consisted of extra-articular and process calcaneal fractures. Data were collected via the patient registry, radiographs, and a standardized questionnaire (Foot and Ankle Outcome Score, FAOS). For outcome analysis, non-parametric Mann–Whitney U-test was performed, and Spearman's rank correlation coefficient was calculated. Results: In total, the functional outcome of 79 patients with calcaneal fractures was analyzed. In group 1 (n = 43), the mean FAOS score was 65.5 ± 18.9. The surgically treated patients with a Sanders type II calcaneal fracture had a mean FAOS score of 72.9 ± 17.2, type III fractures had 65.6 ± 20.8, and type IV had 61.1 ± 19 (p = 0.15). The reoperation rate was 22%, most frequently caused by wound complications (10%). The mean follow-up time was 64.5 ± 44 months. The mean FAOS score of group 2 (n = 36) was 75.2 ± 18.4, and 83% of the patients (=30) were managed conservatively. Only one out of six operatively managed patients had a reoperation due to regular implant removal. The mean follow-up time was 31 ± 25.9 months. Conclusion: Intra-articular calcaneal fractures are severe injuries of the hindfoot leading to a fair to poor functional outcome in the majority of the patients. Complications regarding wound healing are the most common causes for revisional surgery. Extra-articular calcaneal fractures are a heterogenous entity commonly managed non-operatively. Overall, they show a better functional outcome in comparison to intra-articular calcaneal fractures.

Abstract
Hintergrund Mittelfußfrakturen gehören zu einer der häufigsten Verletzungen des Fußes und treten v. a. bei Patienten zwischen dem 40. und 50. Lebensjahr auf. Insbesondere die Verletzung mehrerer Mittelfußknochen kann zu bleibenden Einschränkungen führen, und daher war das Ziel dieser Studie, das funktionelle Outcome von Mittelfußfrakturen mittels eines validierten selbstberichteten patientenbasierten Ergebnisfragebogens zu untersuchen. Material und Methoden Im Zeitraum von 2003 bis 2015 wurden alle Patienten mit einer Mittelfußfraktur mit konservativer sowie operativer Behandlung in diese retrospektive Kohortenstudie eingeschlossen. Es wurden demografische Daten, Art der Fraktur (AO-Klassifikation), Behandlung, Reoperationsrate sowie das funktionelle Ergebnis mittels Foot and Ankle Outcome Score (FAOS) erfasst. Der Mann-Whitney-U-Test und Exakte Fisher-Test wurden bei der statistischen Analyse eingesetzt. Ergebnisse Insgesamt wurden in diese Studie 111 Patienten mit 81 isolierten und 30 multiplen Mittelfußfrakturen eingeschlossen. Das Durchschnittsalter der Patienten war 45 ± 15,2 Jahre mit insgesamt 48 Männern (43 %) und 63 Frauen (57 %). Patienten mit isolierter Mittelfußfraktur hatten einen FAOS von 88 ± 17,1. Die Patienten mit multiplen Mittelfußfrakturen erzielten einen FAOS von 78 ± 17,7 (p = 0,046). In der Gruppe der isolierten Mittelfußfrakturen wurden 43 Patienten (53 %) operativ behandelt. Hiervon zeigten 36 Patienten eine C‑Fraktur (84 %). In der Gruppe der multiplen Mittelfußfrakturen wurden 16 Patienten (53 %) operativ behandelt. Diskussion Das funktionelle Outcome nach isolierten Mittelfußfrakturen ist sowohl nach operativer als auch konservativer Therapie gut bis sehr gut. Einfache Frakturen lassen sich erfolgreich konservativ und komplexe, mehrfragmentäre Frakturen operativ behandeln. Bei Frakturen von mehr als einem Mittelfußknochen ist das Ergebnis signifikant schlechter, und es bleiben vom Patienten berichtete Einschränkungen zurück.

Abstract
Background In the modern western world appraisal of economical points such as treatment and disability after trauma present a financial burden. In this context open reduction internal fixation techniques allowing for early full weight bearing might not only improve the clinical outcome but also shorten the period of disability in working life. The aim of the study was to analyze whether ORIF of ankle fractures using either a standard semitubular plate or a new polyaxial locking plate system result in a better clinical outcome. Methods In this prospective study, all patients with distal fibula fractures (AO 44 B1.1, B1.2, B1.3), with indication for surgery were included. Patients were randomized to either the DePuy Synthes® one-third semitubular plate (Group I) or NEWCLIP TECHNICS, Active Ankle® polyaxial locking plate (Group II). Primary outcome parameter was function of the ankle joint, assessed by the Olerud and Molander ankle score, Foot and Ankle outcome score and Karlsson and Peterson Scoring System for Ankle function. Secondary outcome parameter were postoperative complications. Superficial wound infection, delayed wound healing, mechanically prominent implant, skin irritations were considered as minor and deep wound infection, material loosening, loss of reduction were regarded as major complications requiring revision surgery. Clinical and radiological follow-up were performed 6 and 12 weeks, 6 months and 1 year postoperatively. Results Fifty-two patients (31 W/21 M) with a mean age of 43 yrs. (range 22–64 yrs.) were enrolled. Seven patients (13.5%) were excluded, so that 45 patients were available for follow up. Twenty-five patients were treated with DePuy Synthes® one-third semitubular plate (55.6%; group I) while 20 patients received an anatomically preformed polyaxial locking plate (44.4%, group II). Four minor complications occurred in Group I (16%) compared to two minor complications in group II (10%). Significant better clinical results regarding OMAS (p < 0.02, < 0.04), KPSS (p < 0.04) and FAOS (p < 0.02, < 0.03) were observed 6 and 12 weeks after surgery in group II. Conclusions The results of the presented study demonstrate a significant better clinical functional outcome in the early postoperative follow-up in patients treated with a polyaxial locking plate. Furthermore, our data show that ORIF using polyaxial locking plates in combination with an early postoperative weight bearing presents a safe, stable treatment option for ankle fractures so that patients benefit especially in the early stages of recovery.

Abstract
BACKGROUND Fractures of the proximal humerus are often associated with lesions of the long head of the biceps (LHB) tendon. This often leads to prolonged shoulder pain. Hence, many surgeons decide to perform a tenodesis of the LHB tendon simultaneous to ORIF. The purpose of this study was to evaluate the postoperative outcome after interlocking plate fixation and biceps tenodesis for treating proximal humerus fractures. METHODS 56 patients (38 females, 18 male) suffering from proximal humerus fractures who underwent surgery were retrospectively included. 26 of these 56 patients (19% Neer II, 38% Neer III, 43% Neer IV) were treated with simultaneous tenodesis of the LHB tendon when ORIF using interlocking plate fixation was performed. 30 patients (17% Neer II, 40% Neer III, 43% Neer IV) served as control group receiving only interlocking plate fixation. The patients were asked to complete the Munich Shoulder Questionnaire (MSQ) for evaluation of postoperative shoulder function. Results of the Disabilities of the Arm, Shoulder and Hand (DASH) Score and Shoulder Pain and Disability Index (SPADI) were calculated from the MSQ. Patients were clinically evaluated for a positive O'Brien test and Popeye sign. RESULTS The tenodesis group demonstrated significant superior outcome regarding the MSQ (mean 90.47 points vs. 79.41 points, p = 0.006), DASH Score (mean 4.2 points vs. 16.81 points, p = 0.017) and SPADI (mean 94.59 points vs. 83.56, p = 0.045). Flexion, external rotation and the capability of throwing a soft ball were significantly improved in the tenodesis group compared to the control group. The O'Brien test as indicator for lesions of the LHB was positive in fewer patients of the tenodesis group (2/26, vs. 21/30, p = 0.001). There was no significant difference of a positive Popeye Sign. CONCLUSION Our results show evidence of an improved shoulder function when a simultaneous tenodesis of the LHB tendon is performed during treatment of proximal humerus fractures using interlocking plate fixation.

Abstract
Background The city of Munich uses web-based information system IVENA to promote exchange of information regarding hospital offerings and closures between the integrated dispatch center and hospitals to support coordination of the emergency medical services. Hospital crowding resulting in closures and thus prolonged transportation time poses a major problem. An innovative discrete agent model simulates the effects of novel policies to reduce closure times and avoid crowding. Methods For this analysis, between 2013 and 2017, IVENA data consisting of injury/disease, condition, age, estimated arrival time and assigned hospital or hospital-closure statistics as well as underlying reasons were examined. Two simulation experiments with three policy variations are performed to gain insights on the influence of diversion policies onto the outcome variables. Results A total of 530,000+ patients were assigned via the IVENA system and 200,000+ closures were requested during this time period. Some hospital units request a closure on more than 50% of days. The majority of hospital closures are not triggered by the absolute number of patient arrivals, but by a sudden increase within a short time period. Four of the simulations yielded a specific potential for shortening of overall closure time in comparison to the current status quo. Conclusion Effective solutions against crowding require common policies to limit closure status periods based on quantitative thresholds. A new policy in combination with a quantitative arrival sensor system may reduce closing hours and optimize patient flow.

Abstract
INTRODUCTION Successful treatment of periprosthetic shoulder fractures depends on the right strategy, starting with a well-structured classification of the fracture. Unfortunately, clinically relevant factors for treatment planning are missing in the pre-existing classifications. Therefore, the aim of the present study was to describe a new specific classification system for periprosthetic shoulder fractures including a structured treatment algorithm for this important fragility fracture issue. METHODS The classification was established, focussing on five relevant items, naming the prosthesis type, the fracture localisation, the rotator cuff status, the anatomical fracture region and the stability of the implant. After considering each single item, the individual treatment concept can be assessed in one last step. To evaluate the introduced classification, a retrospective analysis of pre- and post-operative data of patients, treated with periprosthetic shoulder fractures, was conducted by two board certified trauma surgery consultants. RESULTS The data of 19 patients (8 male, 11 female) with a mean age of 74 ± five years have been analysed in our study. The suggested treatment algorithm was proven to be reliable, detected by good clinical outcome in 15 of 16 (94%) cases, where the suggested treatment was maintained. Only one case resulted in poor outcome due to post-operative wound infection and had to be revised. CONCLUSIONS The newly developed six-step classification is easy to utilise and extends the pre-existing classification systems in terms of clinically-relevant information. This classification should serve as a simple tool for the surgeon to consider the optimal treatment for his patients.

Abstract
Background Management of distal humeral fractures remains to be one of the most challenging aspects in trauma surgery. Low profile plating systems with variable angle screw fixation represent a crucial advancement to the established angular stable locking plates with considerable attention in current research. The aim of the prospective randomized trial was to review the preliminary results and patients’ outcome following treatment with these newly developed implants and to rule out potential differences in fracture treatment of two different plating systems. Methods Twenty patients with distal humeral fractures (AO 13-A1 – AO 13-C3) were included in the current study since 2014. After completing the randomization plan, patients were distributed into two groups for different variable angle locking plates (DePuy Synthes® VA-LCP vs. Medartis® Aptus Elbow). Functional elbow scoring (ROM, MEPS, QuickDASH) served as primary outcome parameter, while radiological fracture consolidation served as secondary outcome parameter. Follow-ups were conducted 6 weeks, 12 weeks, 6 months and 12 months after the operation. Results Seventeen of 20 patients (85%) concluded all follow-up examinations. Postoperative elbow extension deficiencies showed significant differences between the two groups in all follow-up examinations with a mean of Ø 18 +/− 7.4 degrees in the DePuy Synthes® VA-LCP group compared to a mean of Ø 6.5 +/− 7.5 degrees in the Medartis® Aptus Elbow group (p = 0.002) 12 months postoperatively. Functional scoring showed a disparate pattern. The Medartis® Aptus Elbow group achieved significantly better MEP scores during follow-up. However, the analysis of the QuickDash revealed better results of the DePuy Synthes® VA-LCP group in the first half and better results of the Medartis® Aptus Elbow group in the second half of the follow-up examination instead. Conclusions Considering the complexity of distal humeral fractures, the usage of anatomically preshaped low profile variable angle locking plates for operative treatment leads to good clinical results. Even though there might be some advances of the Medartis® Aptus Elbow plating system concerning postoperative ROM and elbow function, a consistent difference in the overall clinical outcome between the two plating systems could not be detected.

Abstract
PURPOSE To detect concomitant intra-articular glenohumeral injuries, in acute displaced fractures of the lateral clavicle, initially missed due to unfeasible clinical evaluation of the acutely injured shoulder. METHODS All patients suffering from an acute displaced lateral clavicle fracture with indication to surgical treatment underwent diagnostic shoulder arthroscopy prior to open reduction and internal fixation. In case of therapy-relevant intra-articular glenohumeral injuries, subsequent surgical treatment was performed. RESULTS Intra-articular injuries were found in 13 of 28 patients (46.4 %) with initially suspected isolated lateral clavicle fracture. Additional surgical treatment was performed in 8 of 28 cases (28.6 %). Superior labral anterior-posterior (SLAP) lesions were observed in 4 of 28 patients (14.3 %; SLAP II a: 1; II b: 1; III: 1; and IV: 1). Lesions of the pulley system were found in 3 of 28 patients (10.7 %; Habermeyer III°). One partial articular supraspinatus tendon avulsion lesion (3.6 %) and one lesion of the subscapularis tendon (3.6 %; Fox and Romeo II°) were observed. CONCLUSIONS Traumatic concomitant glenohumeral injuries in lateral clavicle fractures seem to be more frequent than expected in general. Subsequent surgical treatment of these formerly missed but therapy-relevant injuries may increase functional outcome and reduce complication rate. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE To develop and validate an elbow self-assessment score considering subjective as well as objective parameters. METHODS Each scale of the American Shoulder and Elbow Surgeons-Elbow Score, the Broberg and Morrey rating system (BMS), the Patient-Rated Elbow Evaluation (PREE) Questionnaire, the Mayo Elbow Performance Score (MEPS), the Oxford Elbow Score (OES) and the Quick Disabilities of the Arm, Shoulder and Hand (Quick-DASH) was analysed, and after matching of the general topics, the dedicated items underwent a fusion to the final ESAS's item and a score containing 22 items was created. In a prospective clinical study, validity, reliability and responsiveness in physically active patients with traumatic as well as degenerative elbow disorders were evaluated. RESULTS Validation study included 103 patients (48 women, 55 men; mean age 43 years). A high test-retest reliability was found with intraclass correlation coefficients of at least 0.71. Construct validity and responsiveness were confirmed by correlation coefficients of -0.80 to -0.84 and 0.72-0.84 (p <0.05). Correlation coefficients of the ESAS and well-established elbow rating systems BMS, PREE, MEPS, OES and Quick-DASH were between 0.70 and 0.90 (p < 0.05). CONCLUSIONS With this novel Elbow Self-Assessment Score (ESAS), a valid and reliable instrument for a qualitative self-assessment of subjective and objective parameters (e.g. range of motion) of the elbow joint is demonstrated. Quantitative measurement of elbow function may not longer be limited to specific elbow disorders or patient groups. The ESAS seems to allow for a broad application in clinical research studying elbow patients and may facilitate the comparison of treatment results in elbow disorders. The treatment efficacy can be easily evaluated, and treatment concepts could be reviewed and revised. LEVEL OF EVIDENCE Diagnostic study, Level III.

Abstract
INTRODUCTION For comminuted and displaced fractures of the radial head open reduction and internal fixation (ORIF) is recommended nowadays as the treatment of choice. Due to the development of locking plates the possibilities of ORIF in complex fracture types were extended. The purpose of this retrospective survey therefore was to review the preliminary subjective and objective results in patients treated by anatomically preshaped locked plating. A reliable fracture healing for these recently introduced plating devices was hypothesized. MATERIALS AND METHODS Subjective and objective criteria included patient's satisfaction, pain rating on a visual analogue scale (VAS) and active range of motion (ROM) compared to the contralateral armside. Functional scoring included the Morrey elbow performance score (MEPS), the QuickDASH and the elbow self-assessment score (ESAS). Furthermore, follow-up radiographs were reviewed. RESULTS Between 2011 and 2014 a total of 24 patients were managed with ORIF using anatomically preshaped low-profile locking plates. All patients had suffered from comminuted radial head fractures (type III-IV according to Mason classification). Twenty of 24 patients returned for follow-up examination after a mean of 30 months (range 18-53 months). Patients' satisfaction was rated as highly satisfied in 17 cases and satisfied in 3 cases. An unrestricted ROM for extension-flexion arc and pronation-supination arc was rated in 10 cases. Minor ROM deficiencies with a 5° limited extension compared to the contralateral side was evaluated in 6 cases. Only four patients were rated with and extension and supination deficiency of 10°, one of whom with an additional pronation deficiency of 10°. The calculated MEPS was Ø 98 ± 4 (range 85-100), and the QuickDASH was Ø 3 ± 6 (range 0-21). The ESAS was completed by 18 patients with a mean of Ø 96.54 ± 2.95 (range 94-100) indicating a non-restricted elbow function. CONCLUSIONS The treatment of comminuted radial head fractures using anatomically preshaped locking radial head plates represents a reliable and safe surgical approach, leading to good to excellent functional results. Being aware of the importance of the radial head for elbow stability, open reduction and internal fixation should be preferred prior to radial head resection or replacement in complex radial head fractures. Further trials with a higher number of patients are needed to confirm the advantages of preshaped radial head plates.

Abstract
Background Treatment of clavicular non- and malunion is still challenging. Current surgical procedures often result in frustrating functional outcome along with high-grade subjective impairment and increased rates of revision surgery. However, the combination of biological augmentation with vital bone graft and a biomechanically sufficient fixation system seems to be a promising concept of treatment. Methods In this retrospective study, 14 patients with a mean age of 44 years (26–67 years) suffering from non-union (n = 11) and/or malunion (n = 3) of the clavicle were enrolled. All patients were surgically treated using an anatomical precontoured locking compression plate (LCP) and autologous iliac crest bone graft. Functional outcome was assessed using the age- and sex-specific relative Constant Score. Results Mean follow-up was 27 months (range 12–44 months). The relative Constant Score significantly improved from preoperative 61 ± 8 (43–72) to 82 ± 10 (65–100) points at the final follow-up examination (p < 0.05). All patients showed bony union radiographically. One patient presented with a re-fracture of the clavicle nearly 3 years after revision surgery and 5 weeks after implant removal. Secondary fractures at the donor site of the anterior superior iliac spine were recorded in two patients. Conclusions Iliac crest bone graft and anatomic locking plate fixation allow for a safe and adequate stabilization and radiographical bony union in non- and malunions of the clavicle with a high degree of patient satisfaction. However, secondary fractures of the anterior superior iliac spine constitute relevant complications and the time of hardware removal should be considered carefully.

Abstract
BACKGROUND Compromised bone stock and heavily impaired structural integrity after multiple endoprosthetic revision surgeries can lead to a comparable condition as encountered in musculoskeletal tumor surgery. Total femoral replacement (TFR) can restore femoral integrity and allow patients to resume ambulation. Even though several authors reported their results of TFR, so far many questions are still on debate: Which patients are at risk to experience low functional outcome? Do complications and clinical outcome after TFR depend on the indication for the surgery (e.g. periprosthetic fractures or aseptic loosening) or the age of the patients? The purpose of the present study was to compare complication rates after TFR performed with modular total femur prosthesis MML (Fa. ESKA/Orthodynamics) in patients without malignant disease. METHODS We conducted a retrospective chart review and functional investigation of patients treated with a TFR for non-oncologic conditions from 1995 to 2015 and a minimum follow-up of 2 years. Complications were recorded according to the Henderson-Classification; outcome was evaluated with established clinical scores. The indication for TFR was periprosthetic fracture (Group A, n = 11) or aseptic loosening (Group B, n = 7) with massive bone defect of the femur deemed unsuitable for conventional arthroplastic or biologic reconstruction. RESULTS Eighteen patients matched the inclusion criteria and could be investigated clinically after a mean follow-up of 80 months (range: 28-132). Before TFA, all patients had previously undergone multiple operations (range: 1-8). The overall failure rate for any reason was 72% (n = 13/18), leading to a total of 37 surgical revisions with total exchange of TFR in 22% (n = 4/18). Most common failure mechanism was Type I (soft tissue), followed by Type IV (infection) and Type III (mechanical failure). According to Enneking's functional evaluation method (MSTS-Score), the function ranged from 1 to 15 with a mean of 10 ± 4 out of 30. CONCLUSION TFR is a salvage procedure to restore mechanical integrity and regain functional ability after extensive femoral bone loss. Outcome of the patients in the present study did mainly depend on the age at reconstruction and not on the indication for TFR.

Abstract
BACKGROUND The aim of this study was to evaluate potential benefits of a new diagnostic software prototype (Trauma Viewer, TV) automatically reformatting computed tomography (CT) data on diagnostic speed and quality, compared to CT-image data evaluation using a conventional CT console. METHODS Multiple trauma CT data sets were analysed by one expert radiology and one expert traumatology fellow independently twice, once using the TV and once using the secondary conventional CT console placed in the CT control room. Actual analysis time and precision of diagnoses assessment were evaluated. The TV and CT-console results were compared respectively, but also a comparison to the initial multiple trauma CT reports assessed by emergency radiology fellows considered as the gold standard was performed. Finally, design and function of the Trauma Viewer were evaluated in a descriptive manner. RESULTS CT data sets of 30 multiple trauma patients were enrolled. Mean time needed for analysis of one CT dataset was 2.43 min using the CT console and 3.58 min using the TV respectively. Thus, secondary conventional CT console analysis was on average 1.15 min shorter compared to the TV analysis. Both readers missed a total of 11 diagnoses using the secondary conventional CT console compared to 12 missed diagnoses using the TV. However, none of these overlooked diagnoses resulted in an Abbreviated Injury Scale (AIS) > 2 corresponding to life threatening injuries. CONCLUSIONS Even though it took the two expert fellows a little longer to analyse the CT scans on the prototype TV compared to the CT console, which can be explained by the new user interface of the TV, our preliminary results demonstrate that, after further development, the TV might serve as a new diagnostic feature in the trauma room management. Its high potential to improve time and quality of CT-based diagnoses might help in fast decision making regarding treatment of severely injured patients.

Abstract
Anterior tibial pseudoaneurysm is a rare complication after interlocking screw insertion in tibial nailing. We present the case of a 28-year-old male patient with this complication with a 6-week delay after tibial nailing of a right tibial fracture type 42-A1 of the Association for the Study of Internal Fixation (AO/ASIF) classification. On presentation to our emergency department, the patient's complaints were solemnly intermittent pain and occasional swelling of his proximal lower leg. Deep vein thrombosis, compartment syndrome, and implant dislocation were ruled out, and the patient was discharged after his symptoms improved without further intervention. Four weeks later, the patient was readmitted for similar symptoms. A computed tomography (CT) angiography then revealed a pseudoaneurysm of the anterior tibial artery at the level of the proximal interlocking screw insertion. Aneurysmal sac excision with vessel repair was performed while reconstructing the additional dislocated proximal fibular fracture using standard AO/ASIF plating. Postoperatively, sufficient flow through the repaired vessel was documented using Doppler ultrasound and CT angiography. However, the patient sustained a temporal damage to the peroneal nerve after surgery. This case highlights the risk of a pseudoaneurysm of the anterior tibial artery after interlocking screw insertion as a rare but major complication of a routine surgical procedure. Early ultrasound diagnostics, CT angiography, or magnetic resonance (MR) angiogram should be performed to prevent the delay in diagnosis and treatment of such complications.

Abstract
INTRODUCTION Osteoporosis is a highly focused issue in current scientific research and clinical treatment. Especially in rotator cuff repair, the low bone quality of patients suffering from osteoporosis is an important issue. In this context, non-biological solutions using PMMA for anchor augmentation have been developed in the recent past. The aim of this study was to evaluate whether augmentation of suture anchors using bio-absorbable osteoconductive fiber-reinforced calcium phosphate results in improved failure load of suture anchors as well. MATERIALS AND METHODS Altogether 24 suture anchors (Corkscrew FT 1 Suture Anchors, Arthrex, Naples, FL, USA) were evaluated by applying traction until pullout in 12 paired fresh frozen human cadaver humeri using a servo-hydraulic testing machine. Inclusion criteria were an age of more than 64 years, a macroscopically intact RC and an intact bone. The anchors were evaluated at the anterolateral and posteromedial aspect of the greater tuberosity. 12 suture anchors were augmented and 12 suture anchors were conventionally inserted. RESULTS The failure load was significantly enhanced by 66.8 % by the augmentation method. The fiber-reinforced calcium phosphate could be easily injected and applied. CONCLUSION The bio-absorbable cement in this study could be a promising augmentation material for RC reconstructions, but further research is necessary-the material has to be evaluated in vivo.

Abstract
BACKGROUND Trauma surgery is a discipline in which the training phase for specialization requires a technical and time-intensive learning curve, including the repetitive training of manual skills. This results in prolonged operation times and thus elevated costs. OBJECTIVES The present study retrospectively examines operations in trauma surgery and orthopaedics at a Munich university hospital according to the required curriculum for further specialist training. The duration of procedures at the various training levels and the resulting costs were compared. MATERIAL AND METHODS Based on digital surgical records, more than 2,000 surgical interventions were analysed and checked that they fulfilled the practical requirements. Patients with multiple injuries and polytrauma, in addition to irregularly complex cases, were removed from the calculation to ensure high comparability of the individual cases. This yielded more than 1,000+ cases for evaluation. The per-minute cost was calculated to allow for the translation of operating time into costs. RESULTS The study shows a prolonged duration of operating time of 19.75 % when the procedure was conducted by residents. This prolongation can be split into 37 subgroups according to body region and type of procedure. The prolongation of operation time could be quantified as a specific prolongation per cluster, in addition to cumulative prolongation. By including the operating costs, the operation-dependent training costs are shown as an exact sum of Euros. CONCLUSION Surgical training of residents costs hospitals the appropriate amounts of time and money and reduces the overall number of procedures performed, justifying special consideration of the financing of training hospitals.

Abstract
Background The effects of private transportation (PT) to definitive trauma care in comparison to transportation using Emergency Medical Services (EMS) have so far been addressed by a few studies, with some of them finding a beneficial effect on survival. The aim of the current study was to investigate epidemiology, pre- and in-hospital times as well as outcomes in patients after PT as compared to EMS recorded in the TraumaRegister DGU®. Methods All patients in the database of the TraumaRegister DGU® (TR-DGU) from participating European trauma centers treated in 2009 to 2013 with available data on the mode of transportation, ISS ≥ 4 and ICU treatment were included in the study. Epidemiological data, pre- and in-hospital times were analysed. Outcomes were analysed after adjustment for RISC-II scores. Results 76,512 patients were included in the study, of which 1,085 (1.4 %) were private transports. Distribution of ages and trauma mechanisms showed a markedly different pattern following PT, with more children < 15 years treated following PT (3.3 % EMS vs. 9.6 for PT) and more elderly patients of 65 years or older (26.6 vs 32.4 %). Private transportation to trauma care was by far more frequent in Level 2 and 3 hospitals (41.2 % in EMS group vs 73.7 %). Median pre-hospital times were also reduced following PT (59 min for EMS vs. 46 for PT). In-hospital time in the trauma room (66 for EMS vs. 103 min for PT) and time to diagnostics were prolonged following PT. Outcome analysis after adjustment for RISC-II scores showed a survival benefit of PT over EMS transport (SMR for EMS 1.07 95 % CI 1.05–1.09; for PT 0.85 95 % CI 0.62–1.08). Discussion The current study shows a distinct pattern concerning epidemiology and mechanism of injury following PT. PT accelerates the median pre-hospital times, but prolongs time to diagnostic measures and time in the trauma room. Conclusions In this distinct collective, PT seemed to lead to a small benefit in terms of mortality, which may reflect pre-hospital times, pre-hospital interventions or other confounders.

Abstract
BACKGROUND Isolated radial neck fractures occur only in rare cases. The majority of cases are non-displaced or minimally displaced and can be treated conservatively. Conservative treatment, however, might result in secondary displacement and/or malunion. On the other hand, open reduction and internal fixation (ORIF) as standard surgical approach in adults is associated with non-union, implant-related complications and reduced range of motion. For isolated radial neck fractures with an intact radial head, the procedure of centromedullary pinning--as widely used in the treatment of paediatric radial neck fractures--might be an alternative operative technique in adults as well. The purpose of this retrospective case series therefore was to evaluate the functional outcome of radial neck fractures treated by intramedullary pinning. METHODS Between 02/2009 and 12/2014, a total of eight patients with isolated radial neck fractures (Mason type-III; Judet Type II and III) were treated with centromedullary pinning using titanium elastic nails (TEN). The mean age of the patients was 39 years (range 23-90 years) with a mean interval from injury to surgery of 2.9 days (range 1-7 days). Subjective and objective criteria included patient's satisfaction, pain rating on a visual analogue scale (VAS) and active range of motion (ROM) compared to the contralateral armside. Functional scoring included the Morrey Elbow Score (MEPS), the QuickDASH and the Elbow Self Assessment Score (ESAS). Furthermore, follow-up radiographs were evaluated. RESULTS Seven of the eight patients were available for follow-up after a mean of 36 months (range 6-64 months). Patients' satisfaction was rated very good in four cases, good in two cases and sufficient in one case. An unrestricted active ROM compared to the contralateral side for extension-flexion arc and for pronation-supination-arc with full strength was rated in all cases. The Elbow Self Assessment Score was 98.52 ± 1.95 (range 96-100), the calculated Mayo elbow performance score was 95.71 ± 7.32 (range 85-100) and the QuickDASH score was 6.81 ± 10.42 (range 0-27). There were no complications as infection, non-union, heterotopic ossifications or secondary loss of reduction of the radial head. Only one patient complained about pain resulting from an affection of the superficial radial nerve. CONCLUSION In the present cohort, good to excellent results without relevant complications were seen. The technique of intramedullary pinning as described in the treatment of isolated radial neck fractures in children represents a suitable and reliable method in adults as well. In selected cases, this technique can be recommended as an alternative, minimal-invasive approach to the radial head plate osteosynthesis.

Abstract
BACKGROUND Diagnosis and treatment of stress fractures still remains to be a clinical and radiological challenge. Therapeutic options vary from conservative treatment to surgical treatment without a clear treatment concept. Recently the combination of PET and MRI has been introduced, aiming a superior diagnostic accuracy in clinical practice. Therefore the aim of our study was to analyse whether PET-MRI would be a feasible technique to recognize stress fractures of the foot and to analyse if our conservative treatment plan leads to a good clinical outcome. METHODS Therefore, 20 patients with suspected stress fractures of the foot and ankle underwent plain radiography and (18)F-Fluoride PET-MRI. Two blinded readers assessed in consensus both imaging techniques for the presence of stress fracture, stress reaction or osteoarthritis. Patients with stress fractures or stress reactions in the foot and ankle area underwent our conservative treatment plan, with immobilization in a VACO®ped cast for 6 weeks under partial weight bearing on forearm crutches. The benefit of our conservative therapeutic concept was evaluated by the patients on the basis of VAS and FAOS scoring systems before and after treatment. RESULTS 8 out of 20 patients underwent conservative treatment after diagnosis of either a stress fracture or a stress reaction of the foot and ankle area. PET-MRI identified four stress fractures and seven stress reactions. In all cases, no pathological findings were present on plain X-ray. FAOS and VAS significantly improved according to the patients' records. CONCLUSIONS PET-MRI seems to be a useful modality to diagnose stress fractures and stress reactions of the foot and ankle area, especially when conventional modalities, such as plain radiographs fail. Conservative management is a promising therapeutic option for the treatment of stress fractures. To rule out the benefits compared to a surgical treatment plan, further studies are needed.

Abstract
Background Tension-band wiring (TBW) is a well-established fixation technique for two-part, transverse fracture types of the olecranon. However, complication rates up to 80 % are reported. By reporting on the enormous impact on the patient if failed the aim of the present report was to emphasize the importance of correct K wire positioning in TBW. Case presentation We present the case of a 49-year-old woman who suffered from a radioulnar synostosis of the forearm due to malpositioned K wires after TBW treatment. The patient was treated by heterotopic bone resection supported by ossification prophylaxis (radiotherapy and Indomethacin). At follow-up of 12 months after revision surgery, elbow motion was unrestricted with a strength grade 5/5. The patient was free of pain and reported no restrictions in daily as well as sporting activities. Radiologic assessment showed no recurrence of heterotopic bone tissue. Conclusion Intraoperative radiographic and clinical examination of the elbow is highly recommended to identify incorrect hardware positioning and, therefore, to avoid serious postoperative complications in TBW.

Abstract
Background Locking plate fixation of displaced fractures of the proximal humerus is still accompanied by a distinct complication rate, especially in case of osteoporotic bone, short-segment fracture length and comminution of the medial calcar. Secondary loss of reduction leading to varus deformity and screw cutout most frequently lead to surgical revision. The aim of the present study was to evaluate the clinical and radiological outcome of a recently developed polyaxial locking plate that allows for the additional placement of a helical blade device, aiming for support of the medial calcar. Methods In this prospective study, 17 patients with a mean age of 63.0 ± 16.0 years suffering from displaced fractures of the proximal humerus (Neer type two-, three- and four-part) were enrolled. All patients were surgically treated using a polyaxial locking plate with additional blade device (group PAB, n = 12) or without blade device (group PA, n = 5). Functional outcome was recorded using the Munich Shoulder Questionnaire allowing for qualitative self-assessment of the Shoulder Pain and Disability Index (SPADI), the Disability of the Arm, Shoulder and Hand (DASH score) and the Constant Score. Radiological outcome was assessed by analyzing standardized true anterior–posterior and outlet-view radiographs with respect to radiographic evidence of secondary varus displacement, cutout of screws and hardware failure. Results were compared to an age-, gender- and fracture type-matched collective treated by monoaxial locking plate fixation (group MA, n = 15). Results The mean follow-up was 12.4 ± 2.9 months after surgery. There were no statistical significant differences in clinical outcome in all three groups. Group MA and group PA revealed significant secondary varus displacement in comparison to group PAB at the final follow-up compared to postoperative analysis (p < 0.001). The distance between the blade and the articular surface showed no significant increase in group PAB at the final follow-up compared to postoperative analysis. Not-implant-related complications were seen in one and implant-related complications were seen in two patients in group PAB. Conclusions Polyaxial locking plate fixation with a blade device to restore medial cortical support reduces the risk of secondary varus displacement even in proximal humeral fractures of the elderly in comparison to monoaxial and polyaxial locking plate fixation without blade insertion.

Abstract
BACKGROUND Traumatic carotid artery dissections are very rare, often overlooked and life-threatening injuries. Diagnosis and treatment are difficult especially in multiple injured patients. CASE PRESENTATION We report on a 28-year-old female major trauma patient (injury severity score, ISS 50) who was involved in a motor vehicle accident. She was primarily transferred to a level II trauma center. After initial assessment and operative management, an anisocoria was diagnosed on the intensive care unit. Subsequent CT angiography and extracranial duplex sonography revealed a bilateral internal carotid artery dissection. The patient was transferred to our level I trauma center where conservative treatment with high-dose heparin therapy was started at day two after trauma. Outcome after 6 months was very good. CONCLUSION Besides presenting the case and outcome of this patient, the article discusses the diagnostic and therapeutic management of this extremely rare and often overlooked dangerous injury. To avoid overlooking carotid artery dissections, CT angiography of the neck region should be generously included into the initial multislice CT whole-body scan, when the injury results from an according trauma. For the best outcome, sites of hemorrhage should be abolished quickly and the anticoagulative therapy should be initiated as soon as possible. Interdisciplinary treatment of trauma surgeons and neurologists is crucial.

Abstract
BACKGROUND Fractures of the clavicle present very common injuries with a peak of incidence in young active patients. Recently published randomized clinical trials demonstrated an improved functional outcome and a lower rate of nonunions in comparison to non-operative treatment. Anterior chest wall numbness due to injury of the supraclavicular nerve and postoperative pain constitute common surgery related complications in plate fixation of displaced clavicle fractures. We recently developed a technique for mini open plating (MOP) of the clavicle to reduce postoperative numbness and pain. The purpose of this study was to analyze the size of anterior chest wall numbness and the intensity of postoperative pain in MOP in comparison to conventional open plating (COP) of clavicle fractures. METHODS 24 patients (mean age 38.2 ± 14.2 yrs.) with a displaced fracture of the clavicle (Orthopaedic Trauma Association B1.2-C1.2) surgically treated using a locking compression plate (LCP) were enrolled. 12 patients underwent MOP and another 12 patients COP. Anterior chest wall numbness was measured with a transparency grid on the second postoperative day and at the six months follow-up. Postoperative pain was evaluated using the Visual Analog Scale (VAS). RESULTS Mean ratio of skin incision length to plate length was 0.61 ± 0.04 in the MOP group and 0.85 ± 0.06 in the COP group (p < 0.05). Mean ratio of the area of anterior chest wall numbness to plate length was postoperative 7.6 ± 5.9 (six months follow-up 4.7 ± 3.9) in the MOP group and 22.1 ± 19.1 (16.9 ± 14.1) in the COP group (p < 0.05). Mean VAS was 2.6 ± 1.4 points in the MOP group and 3.4 ± 1.6 points in the COP group (p = 0.20). CONCLUSIONS In our study, MOP significantly reduced anterior chest wall numbness in comparison to a conventional open approach postoperative as well as at the six months follow-up. Postoperative pain tended to be lower in the MOP group, however this difference was not statistically significant. TRIAL REGISTRATION ClinicalTrials.gov NCT02247778 . Registered 21 September 2014.

Abstract
Background Treatment of lateral fractures of the clavicle is challenging and has been controversially discussed for a long time due to high non-union rates in non-operative treatment and high complication rates in surgical treatment. Acromioclavicular joint instability due to the injury of the closely neighbored coraco-clavicular ligaments can result in a cranialization of the medial clavicle shaft. A recently developed implant showed a promising functional outcome in a small collective of patients. Methods In this prospective study, 20 patients with a mean age of 40.7 ± 11.3 years with a dislocated fracture of the lateral clavicle (Jäger&Breitner I-III, Neer I-III) were enrolled. All patients were surgically treated using the locking compression plate (LCP) for the superior anterior clavicle (Synthes®). Functional outcome was recorded using the Munich Shoulder Questionnaire (MSQ) allowing for qualitative self-assessment of the Shoulder Pain and Disability Index (SPADI), of the Disability of the Arm, Shoulder and Hand (DASH) score and of the Constant Score. Acromioclavicular joint stability was evaluated using the Taft-Score. Results The mean follow-up was 14.2 ± 4.0 months. The mean MSQ was 87.0 ± 7.4 points, the mean SPADI 91.1 ± 11.3 points, the mean DASH score 7.6 ± 7.3 points and the mean normative age- and sex-specific Constant Score 85.6 ± 8.0 points. The mean Taft Score resulted in 10.7 ± 1.0 points. The mean Taft Score in lateral clavicular fractures with fracture gap between the coracoclavicular ligaments in combination with a rupture of the conoid ligament (J&B II a, Neer II B; n =11) was with 10.3 ± 0.9 points significantly lower than the mean Taft Score of all other types of lateral clavicle fractures (J&B I, II b, III; n =9) which resulted in 11.3 ± 0.9 points (p < 0.05). Conclusions The Synthes® LCP superior anterior clavicle plate allows for a safe stabilization and good functional outcome with high patient satisfaction in fractures of the lateral clavicle. However, in fractures type Jäger&Breitner II a, Neer II B a significant acromioclavicular joint instability was observed and additional reconstruction of the coracoclavicular ligaments should be performed.

Abstract
The goal of this study was to evaluate the influence of bone morphogenetic protein-2 (BMP-2) on tendon-bone integration in a bovine in vitro cell culture. Seventy-two bovine tendons were cultivated over 3 months. The effects of BMP-2 were evaluated by generation in 4 subgroups. The groups differed in 2 parameters: the application of BMP-2 and the application of primary bovine osteoblasts. Results were analyzed biochemically by determining alkaline phosphatase activity and histologic tendon calcification, both markers for graft incorporation. Histological analysis demonstrated a positive effect of BMP-2 on the production of extracellular matrix and therefore the induction of osteogenesis. In addition, the results showed a superior cell ingrowth on the tendon in the BMP-2-stimulated groups. Calcium carbonate-like structures and organized ossification zones could only be detected in the BMP-2-stimulated tendons. The histological results matched those of the biochemical alkaline phosphatase analysis. The highest alkaline phosphatase activity was detected using BMP-2 stimulation in the first month (P<.001). High alkaline phosphatase values suggest high osteoblast activity and a high potential for mineralization. Furthermore, a positive effect of BMP-2 on fibroblasts existed with regard to the overall integration process. These results confirm the positive influence and triggering effect of BMP-2 on the mineralization process. Bone morphogenetic protein-2 seems to accelerate and optimize tendon-bone integration in the early process of graft incorporation. Besides the influence of BMP-2 on bovine osteoblasts, an additional positive effect of BMP-2 on bovine fibroblasts was detected; therefore, graft incorporation may be carried out by osteoblasts and fibroblasts.
