RESUMO
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.

BACKGROUND: Treatment of medial clavicle fractures is still controversially discussed in the community of upper extremity surgeons. An increasing number of symptomatic non-unions following conservative treatment of displaced fractures led to the development of various surgical approaches. Aim of this study was to evaluate the clinical and radiological outcome following operative treatment of displaced medial end clavicle fractures. METHODS: Patients who presented with a displaced fracture of the medial clavicle between September 2012 and December 2019 were retrospectively enrolled in this study. All patients were operatively treated with open reduction and internal fixation (ORIF) using an anatomically precontoured locking compression plate (LCP) originally designed for the lateral clavicle (Synthes®, Umkirch, Germany). Functional outcome was recorded using the American Shoulder and Elbow Surgeons (ASES) Score, the Munich Shoulder Questionnaire (MSQ), Shoulder Pain and Disability Index (SPADI) and Constant Score. RESULTS: Overall 18 patients with a mean age of 54.5 ± 23.5 years suffering from a displaced fracture of the medial clavicle were identified. The mean follow-up was 40.9 ± 26.2 months. The mean ASES accounted for 88.3 ± 20.8 points, the mean MSQ was 83.1 ± 21.7 points, the mean SPADI was 85.6 ± 22.5 and a mean normative age- and sex-specific Constant Score of 77.5 ± 19.1 points resulted. No minor or major complications were observed. Radiologic fracture consolidation was achieved in all patients after a mean of 6.4 months. CONCLUSION: Surgical treatment of displaced medial clavicle fractures using an anatomically precontoured locking plate originally designed for the lateral clavicle led to very good to excellent clinical and functional results.

PURPOSE: Operative therapy for unstable lateral clavicle fractures is necessary to reduce the risk of bony non-union. Irritation and restriction during sportive activities due to the implanted materials are a common reason for impaired function and implant removal. The aim of this study was to gain information on functional outcome and time until return to sport (RTS) after surgical treatment of unstable lateral clavicle fractures, comparing two coracoclavicular button techniques. METHODS: A retrospective chart review of patients who were consecutively treated for unstable lateral clavicle fractures at our level one trauma center from 2014 to 2018 was conducted. Two different surgical techniques were evaluated and compared. Group 1 was treated using a locking compression plate and knotted DogBone™ Button, while group 2 received an LCP and knotless DogBone™ Button. Functional outcome (ASES (American Shoulder and Elbow Score), Constant-Score, DASH (Disability of Arm, Shoulder and Hand), MSQ (Munich Shoulder Questionnaire) and SPADI (Shoulder Pain and Disability Index) and time until RTS were investigated and compared between both groups, 1 year postoperatively. RESULTS: A total of 56 patients (n = 35 group 1, n = 21 group 2) with a mean age of 45.1 ± 14.6 years met the inclusion criteria. Functional outcome reached good to excellent results (ASES 94.7 ± 9.8, Constant Score 85.1 ± 8.1, DASH 5.5 ± 8.4, MSQ 90.9 ± 7.2, SPADI 96.1 ± 5.7). Implant removal rates were higher in group 1 (48.3% vs. 35.3%) yet without statistical significance (p = 0.122). All patients returned to sports postoperatively with a mean time period until return to sport of 4.6 (3-9) months. CONCLUSION: Locking compression plating and coracoclavicular fixation using a knotless Dogbone™ technique provides good to excellent functional outcomes, a high and fast rate of return to sport and lower irritation rates compared to the knotted DogBone™ technique.
RESUMO
BACKGROUND: Surgical fracture treatment in patients suffering from "osteogenesis imperfecta" (OI) is challenging and often results in unsatisfactory fixation of implants due to altered bone quality. Even the use of locking plates bears a residual risk to develop a loss of reduction leading to secondary fracture dislocation. However, the augmentation with an intramedullary photodynamic bone stabilization system (PBS) (e.g. Illuminoss®) may increase bone stability and allow for a sufficient anchorage of established implants even in OI patients. CASE PRESENTATION: We report the case of a 41-year-old male patient with the diagnosis of OI. He sustained a medial femoral neck fracture (Garden type IV, Pauwels type III) and a fracture of the acetabulum (AO-Type 62-B.3) - both right-sided - after a blunt trauma during a bicycle accident. The medial femoral neck fracture was subsequently surgically treated to preserve the femoral head. After augmentation of the proximal femur with the PBS, a Dynamic Hip Screw (DHS) was implanted. After a short recovery, the acetabular fracture was surgically treated by intramedullary augmentation and locking plate fixation.The patient was discharged seven days after the surgical intervention of the acetabular fracture. Partial weight-bearing activities of the right lower extremity were performed on crutches for 6â¯weeks. The patient was able to do his outpatient rehabilitation program without any complications. He returned to work eight weeks after surgery. After a follow-up of four months, the patient presented full weight-bearing without assistance. No physical complaints were reported 14â¯months after surgery (Harris Hip Score 90). CONCLUSION: To the best of our knowledge, we report the augmentation with a photodynamic bone stabilization system of internal fixation techniques in an OI patient with fractures of the femoral neck and the acetabulum for the first time. This advanced surgical procedure shows the high potential of intramedullary photodynamic bone stabilization in patients with minor bone quality.
RESUMO
BACKGROUND: The primary goal of this study was to analyse the anatomic configuration of the acromio-clavicular joint in a healthy population to be able to develop a classification in a second step. On the basis of the primary findings a secondary goal was to find potential clinical indications in refer to AC-joint dislocation and lateral clavicle fractures. METHODS: The upper thoracic aperture including both shoulder joints as well as both sterno-clavicular joints was retrospectively reformatted in a bone kernel in axial orientation with 0.6 mm slice thickness out of existing multiple trauma or post mortem computed tomography (CT) scans. The DICOM data was converted into the STL file format using a three dimensional (3D) reconstruction software (Smartbrush, Brainlab, Feldkirchen, Germany). The data analysis was performed using a 3D-Computer Aided Detection (CAD) Software (BioCAD, Technical University Munich, Germany). For the analysis, the angle between the cranial surface of the acromion and the tangent to its articular surface was evaluated. Accordingly, the angle between the cranial surface of the clavicle and the tangent to its articular surface was assessed. RESULTS: Overall CT-datasets of 80 healthy patients (40 males, 40 females, mean age 45 ± 8 years) were enrolled and evaluated regarding the configuration of the AC-joint. In this context, three statistically significant (p < 0.001) different configurations of the AC-joint in terms of overhanging acromion, neutral type, overhanging clavicle were identified. The "overhanging acromion" type of AC-joint configuration turned out to be the most common type (46.2%) followed by the "neutral type" (38.4%) and finally the "overhanging clavicle type" (15.4%). CONCLUSIONS: We assume that the shown differences of the AC joint congruency might play an important role in the development of different shoulder injuries resulting from the similar trauma mechanism. However, the proof of these assumptions will be the focus of future studies.

BACKGROUND: There are many approved patient-related outcome measurement tools regarding ankle pathologies. However, there is none incorporating the range of motion (ROM) as an objective parameter. Most instruments focus on subjective parameters such as pain and impairment at work or daily living. Furthermore, the majority is only applicable to a specific pathology. Therefore, the objective of our study was to develop and validate the Munich Ankle Questionnaire (MAQ) as a universal self-assessment score including subjective and objective items. METHODS: The established McGuire Score, Bray Score, Ankle Hindfoot Score (AOFAS) and Olerud and Molander Score were analyzed for relevant items and subscales. Items of interest were then condensed and allocated to the respective subscales of the MAQ. The final MAQ consists of 6 items addressing general and demographic data and 12 items addressing three domains: pain (3 items), work and daily living (5 items), movement and ROM (4 items). The evaluation of validity, reliability and responsiveness of the MAQ was performed in a prospective clinical study including traumatic as well as degenerative ankle pathologies. RESULTS: In total, 148 patients (79 female, 69 male, median age 45 years) were included in the validation study. With intra-class correlation coefficients of at least 0.77, test-retest reliability was proven. Construct validity with a correlation coefficient of 0.82 and responsiveness with a correlation coefficient ranging from 0.42 to 0.47 were confirmed. CONCLUSION: The MAQ is a reliable and valid self-assessment measurement tool for the follow-up examination regarding subjective and objective parameters of traumatic and degenerative ankle pathologies. The MAQ has no limitation to specific disorders and allows a broad application.

BACKGROUND: Data on PNM elastase levels in cerebrospinal fluid following traumatic brain injury (TBI) in humans are not available in the literature. Therefore, the aim of this prospective study was to evaluate the dynamics of PMN elastase in the cerebrospinal fluid (CSF) of patients after TBI. METHODS: Patients suffering from isolated, closed TBI, presenting with an initial Glasgow coma score ≤ 8 and with intracerebral hemorrhage on the initial cranial computed tomography scan (performed within 90 min after TBI) were enrolled. CSF and blood samples were obtained immediately, 12 h, 24 h, 48 h, and 72 h after admission. ELISA testing was used to quantify the PMN elastase levels in CSF. In addition, the ratio of CSF albumin to serum albumin was calculated to evaluate the role of the blood-cerebrospinal fluid barrier (BCSFB). As controls, CSF samples were taken from patients receiving spinal anesthesia for elective orthopedic surgery of the lower extremity. RESULTS: Twenty-three patients meeting the inclusion criteria and ten control patients were enrolled. The PMN elastase showed a significant elevation at 48 and 72 h after TBI. When comparing the PMN elastase levels of patients with intact BCSFB to patients with defective BCSFB, there was no significant difference for the respective observation points. CONCLUSIONS: This is the first study to demonstrate that the PMN elastase levels in CSF significantly increased in the early posttraumatic phase (48 h and 72 h after TBI) in patients. The function of the BCSFB showed no significant influence on the PMN levels.

Calcium sulfate (CS) formulations are frequently implanted as antibiotically impregnated bone substitutes in orthopedic and trauma surgery to prevent or treat bone infections. Calcium ions have been discussed as candidates to accelerate blood coagulation. The goal of this study is to evaluate substance-specific influences of CS formulations on blood coagulation. Specific ELISAs were conducted to determine markers of activated blood coagulation after incubation of human blood with CS beads. Additionally, wettability with freshly drawn human blood was measured. Three different types of CS bone substitute beads were compared (CS dihydrate with tripalmitin, containing Gentamicin (Herafill®-G: Group A) or Vancomycin (CaSO4-V: Group B); and a CS hemihydrate with Tobramycin (Osteoset®: Group C)). Examinations were performed by ELISA assays for F1+2, FXIIa and C3a. Our results prove that none of the CS preparations accelerated single specific assays for activated coagulation markers. This allows the conclusion that neither Herafill®-G (CaSO4-G) nor CaSO4-V alter haemostasis negatively. Blood samples incubated with Osteoset® display an elevated F1+2-activity. The addition of tripalmitin in Herafill®-G shifts the original into a significantly hydrophobic formulation. This was additionally proven by contact angle examination of the three substances with freshly drawn human blood, showing that acceleration of plasmatic coagulation is hindered by lipids and induced by surface effects caused by presence of rapidly soluble calcium ions in the Osteoset® preparation.
RESUMO
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.

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.

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.

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.

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.

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.

RESUMO
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.

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.

BACKGROUND: Although self-assessment questionnaires for the wrist joint are numerous, most validation studies focus on a specific pathology and patient collectives. In addition the available questionnaires focus on subjective parameters such as pain, usual and specific activities but the range of motion (ROM) as an essential objective parameter in wrist disorders is rarely considered. Therefore the purpose of the presented study was to develop and validate a new universally applicable self-assessment score, the Munich Wrist Questionnaire (MWQ), which allows for the assessment of subjective as well as objective parameters of the wrist joint. METHODS: The MWQ consists of 16 items addressing three domains: pain, work and activities of daily living and wrist function including range of motion and grip strength. In a prospective clinical study validity, reliability and responsiveness of the MWQ of physical active patients were evaluated. RESULTS: Validation study included 100 patients (mean age 41 years, SD 16.3 years; range, 18-77 years). Test-retest reliability was substantial, with intraclass correlation coefficients ranging from 0.75 to 0.83 for the three domains. Construct validity and responsiveness were confirmed by correlation coefficients of at least 0.86 for construct validity and for responsiveness ranging from 0.61 to 0.65. CONCLUSIONS: The MWQ presents a valid and reliable instrument for a qualitative self-assessment of subjective and objective parameters (e.g. range of motion) of the wrist joint. Quantitative measurement of wrist function may not longer be limited to specific wrist disorders or patient groups. The MWQ seems to allow for a broad application in clinical research and may facilitate the comparison of treatment results in wrist disorders.

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.

In traumatic brain injury (TBI) the analysis of neuroinflammatory mechanisms gained increasing interest. In this context certain immunocompetent cells might play an important role. Interestingly, in the actual literature there exist only a few studies focusing on the role of monocytes and granulocytes in TBI patients. In this regard it has recently reported that the choroid plexus represents an early, selective barrier for leukocytes after brain injury. Therefore the aim of this study was to evaluate the very early dynamics of CD14+ monocytes and CD15+ granulocyte in CSF of patients following severe TBI with regard to the integrity of the BBB. Cytometric flow analysis was performed to analyze the CD14+ monocyte and CD15+ granulocyte population in CSF of TBI patients. The ratio of CSF and serum albumin as a measure for the BBB's integrity was assessed in parallel. CSF samples of patients receiving lumbar puncture for elective surgery were obtained as controls. Overall 15 patients following severe TBI were enrolled. 10 patients were examined as controls. In patients, the monocyte population as well as the granulocyte population was significantly increased within 72 hours after TBI. The BBB's integrity did not have a significant influence on the cell count in the CSF.
