T1 - Bunnell or cross-lock Bunnell suture for tendon repair? Defining the biomechanical role of suture pretension JF - Journal of Orthopaedic Surgery and Research N2 - Background Suture pretension during tendon repair is supposed to increase the resistance to gap formation. However, its effects on the Bunnell suture technique are unknown. The purpose of this study was to determine the biomechanical effects of suture pretension on the Bunnell and cross-lock Bunnell techniques for tendon repair. Methods Eighty porcine hindlimb tendons were randomly assigned to four different tendon repair groups: those repaired with or without suture pretension using either a simple Bunnell or cross-lock Bunnell technique. Pretension was applied as a 10 % shortening of the sutured tendon. After measuring the cross-sectional diameter at the repair site, static and cyclic biomechanical tests were conducted to evaluate the initial and 5-mm gap formation forces, elongation during cyclic loading, maximum tensile strength, and mode of failure. The suture failure mechanism was also separately assessed fluoroscopically in two tendons that were repaired with steel wire. Results Suture pretension was accompanied by a 10 to 15 % increase in the tendon diameter at the repair site. Therefore, suture pretension with the Bunnell and cross-lock Bunnell repair techniques noticeably increased the resistance to initial gap formation and 5-mm gap formation. The tension-free cross-lock Bunnell repair demonstrated more resistance to initial and 5-mm gap formation, less elongation, and higher maximum tensile strength than the tension-free Bunnell repair technique. The only difference between the tensioned cross-lock Bunnell and tensioned Bunnell techniques was a larger resistance to 5-mm gap formation with the cross-lock Bunnell technique. Use of the simple instead of cross-lock suture configuration led to failure by suture cut out, as demonstrated fluoroscopically. Conclusion Based on these results, suture pretension decreases gapping and elongation after tendon repair, and those effects are stronger when using a cross-lock, rather than a regular Bunnell suture. However, pretension causes an unfavorable increase in the tendon diameter at the repair site, which may adversely affect wound healing.

While being present in only a small share of patients with shoulder trauma, numerous classification systems have been in use over the years for categorization of scapula fractures. The purpose of this study was to evaluate the established AO/OTA classification in comparison to the classification system of Euler and Rüedi (ER) with regard to interobserver reliability and confidence in clinical practice. Methods Based on CT imaging, 149 patients with scapula fractures were retrospectively categorized by two trauma surgeons and two radiologists using the classification systems of ER and AO/OTA. To measure the interrater reliability, Fleiss kappa (κ) was calculated independently for both fracture classifications. Rater confidence was stated subjectively on a five-point scale and compared with Wilcoxon signed rank tests. Additionally, we computed the intraclass correlation coefficient (ICC) based on absolute agreement in a two-way random effects model to assess the diagnostic confidence agreement between observers. Results In scapula fractures involving the glenoid fossa, interrater reliability was substantial (κ = 0.722; 95% confidence interval [CI] 0.676–0.769) for the AO/OTA classification in contrast to moderate agreement (κ = 0.579; 95% CI 0.525–0.634) for the ER classification system. Diagnostic confidence for intra-articular fracture patterns was superior using the AO/OTA classification compared to ER (p < 0.001) with higher confidence agreement (ICC: 0.882 versus 0.831). For extra-articular fractures, ER (κ = 0.817; 95% CI 0.771–0.863) provided better interrater reliability compared to AO/OTA (κ = 0.734; 95% CI 0.692–0.776) with higher diagnostic confidence (p < 0.001) and superior agreement between confidence ratings (ICC: 0.881 versus 0.912). Conclusions The AO/OTA classification is most suitable to categorize intra-articular scapula fractures with glenoid involvement, whereas the classification system of Euler and Rüedi appears to be superior in extra-articular injury patterns with fractures involving only the scapula body, spine, acromion and coracoid process.

T1 - Trans-obturator cable fixation of open book pelvic injuries JF - Scientific Reports N2 - Operative treatment of ruptured pubic symphysis by plating is often accompanied by complications. Trans-obturator cable fixation might be a more reliable technique; however, have not yet been tested for stabilization of ruptured pubic symphysis. This study compares symphyseal trans-obturator cable fixation versus plating through biomechanical testing and evaluates safety in a cadaver experiment. APC type II injuries were generated in synthetic pelvic models and subsequently separated into three different groups. The anterior pelvic ring was fixed using a four-hole steel plate in Group A, a stainless steel cable in Group B, and a titan band in Group C. Biomechanical testing was conducted by a single-leg-stance model using a material testing machine under physiological load levels. A cadaver study was carried out to analyze the trans-obturator surgical approach. Peak-to-peak displacement, total displacement, plastic deformation and stiffness revealed a tendency for higher stability for trans-obturator cable/band fixation but no statistical difference to plating was detected. The cadaver study revealed a safe zone for cable passage with sufficient distance to the obturator canal. Trans-obturator cable fixation has the potential to become an alternative for symphyseal fixation with less complications.

T1 - Development and preclinical evaluation of a cable-clamp fixation device for a disrupted pubic symphysis JF - Communications Medicine N2 - Background Traumatic separation of the pubic symphysis can destabilize the pelvis and require surgical fixation to reduce symphyseal gapping. The traditional approach involves open reduction and the implantation of a steel symphyseal plate (SP) on the pubic bone to hold the reposition. Despite its widespread use, SP-fixation is often associated with implant failure caused by screw loosening or breakage. Methods To address the need for a more reliable surgical intervention, we developed and tested two titanium cable-clamp implants. The cable served as tensioning device while the clamp secured the cable to the bone. The first implant design included a steel cable anterior to the pubic symphysis to simplify its placement outside the pelvis, and the second design included a cable encircling the pubic symphysis to stabilize the anterior pelvic ring. Using highly reproducible synthetic bone models and a limited number of cadaver specimens, we performed a comprehensive biomechanical study of implant stability and evaluated surgical feasibility. Results We were able to demonstrate that the cable-clamp implants provide stability equivalent to that of a traditional SP-fixation but without the same risks of implant failure. We also provide detailed ex vivo evaluations of the safety and feasibility of a trans-obturator surgical approach required for those kind of fixation. Conclusion We propose that the developed cable-clamp fixation devices may be of clinical value in treating pubic symphysis separation.

Bisher ist unklar, welchen Stellenwert diese Fotodokumentation bei der Abrechnungsprüfung durch den Medizinischen Dienst der Krankenkassen (MDK) hat. Fragestellung Kann eine Smartphone-basierte Fotodokumentation die Verteidigung von erlösrelevanten Diagnosen und Prozeduren sowie der Verweildauer verbessern? Material und Methoden Ausstattung der Mitarbeiter mit digitalen Endgeräten (Smartphone/Tablet) in den Bereichen Notaufnahme, Schockraum, OP, Sprechstunden sowie auf den Stationen. Retrospektive Auswertung der Abrechnungsprüfung im Jahr 2019 und Identifikation aller Fallbesprechungen, in denen die Fotodokumentation eine Erlösveränderung bewirkt hat. Ergebnisse Von insgesamt 372 Fallbesprechungen half die Fotodokumentation in 27 Fällen (7,2 %) zur Bestätigung eines Operationen- und Prozedurenschlüssels (OPS) (n = 5; 1,3 %), einer Hauptdiagnose (n = 10; 2,7 %), einer Nebendiagnose (n = 3; 0,8 %) oder der Krankenhausverweildauer (n = 9; 2,4 %). Pro oben genanntem Fall mit Fotodokumentation ergab sich eine durchschnittliche Erlössteigerung von 2119 €. Inklusive Aufwandpauschale für die Verhandlungen wurde somit ein Gesamtbetrag von 65.328 € verteidigt. Diskussion Der Einsatz einer Smartphone-basierten Fotodokumentation kann die Qualität der Dokumentation verbessern und Erlöseinbußen bei der Abrechnungsprüfung verhindern.

N2 - Background Photographic documentation of wounds, decubitus ulcers, tumors, open fractures and infections is an important part of digital patient files. It is unclear whether the photographic documentation has an effect on medical accounting with health insurance companies. Objective It was hypothesized that Smartphone-based systematic photographic documentation can improve the confirmation of proceeds-relevant diagnoses and procedures as well as the duration. Material and methods Staff in the emergency room, operating theater, outpatient clinic and on the wards were equipped with digital devices (Smartphone, tablet) including a photo-app. Medical accounting with the health insurance companies and identification of all case conferences in which the photographic documentation had effected a change in proceeds were analyzed for 2019 in a retrospective manner. Results Overall, 372 cases were discussed of which 27 cases were affected by the digital photographic documentation. Photographic documentation was used for clarification of the operative procedure (n = 5), primary diagnosis (n = 10), secondary diagnosis (n = 3), and length of hospitalization (n = 9). An average of 2119 € was negotiated and added per case affected by photographic documentation. Hereby, a level 1 trauma center gained an estimated 65,328 € in revenue. Discussion The use of Smartphone based photographic documentation can improve the overall quality of patient files and thus avoid loss of revenue. The implementation of digital devices with corresponding software is an important component of the digital structural change in hospitals.

Material und Methoden Es erfolgte eine retrospektive Auswertung schwer verletzter Patienten mit einem Injury Severity Score (ISS) ≥16 zwischen dem 17.03.2020 und 30.04.2020 (landesweiter Shutdown) an einem überregionalen Traumazentrum. Erfasst wurden der Unfallmechanismus, ISS, Versicherungsträger (BG vs. GKV/PKV), ob es sich um einen dokumentierten Suizidversuch handelte, und ob eine operative Intervention innerhalb der ersten 24 h erforderlich war. Als Kontrollgruppe wurden die Daten des gleichen Zeitraums der Jahre 2018 und 2019 ausgewertet. Ergebnisse Es konnte keine wesentliche Veränderung bezüglich der Anzahl an schwer verletzten Patienten festgestellt werden (2018 n = 30, 2019 n = 23, 2020 n = 27). Es zeigten sich insgesamt keine deutlichen Veränderungen der absoluten Zahlen bezüglich der Intensivpflichtigkeit in den ersten 24 h und der Beatmungspflichtigkeit beim Verlassen des Schockraums. Die Anzahl an Patienten, die eine Operation innerhalb der ersten 24 h nach Eintreffen im Schockraum benötigten, war 2020 sogar leicht erhöht, jedoch nicht statistisch signifikant. Der durchschnittliche ISS blieb konstant. Bezüglich der Unfallursache zeigte sich 2020 kein Motorradfahrer, der einen nicht berufsgenossenschaftlich versicherten Unfall erlitt (2018 n = 5, 2019 n = 4, 2020 n = 0). Es wurde 2020 ein erhöhter Anteil an Arbeitsunfällen mit einem ISS ≥16 festgestellt (2018: 10 %, 2019: 26,1 %, 2020: 44,4 %). Diskussion Eine Ausgangsbeschränkung führte zu keiner Reduktion verletzter- und intensivpflichtiger Patienten am untersuchten Zentrum. Auch unter einer landesweiten Ausgangsbeschränkung muss für dieses Patientenkollektiv eine ausreichende Menge an Intensiv- und OP-Kapazitäten vorgehalten werden. Die Bestätigung dieser Ergebnisse durch Auswertung nationaler Register steht noch aus.

T1 - Ergebnisse nach Plattenstabilisierung der Symphysensprengung JF - Der Unfallchirurg N2 - Hintergrund Die Symphysensprengung mit entsprechender Diastase kann durch eine Symphysenplatte stabilisiert werden. Fragestellung Welche Beckenverletzungen werden mit einer Symphysenplatte stabilisiert und wie ist das Outcome? Material und Methoden Retrospektive Auswertung von 64 Patienten über einen Untersuchungszeitraum von 24 Monaten. Ergebnisse Es waren 56 Patienten männlich, 8 weiblich und das mittlere Alter betrug 44 Jahre (SD ± 17). Unfälle im Straßenverkehr waren der führende Grund für die Beckenverletzung. Die Verteilung nach AO-Klassifikation zeigte sich wie folgt: 14-mal B1-, 10-mal B2-, 5‑mal B3-, 23-mal C1-, 9‑mal C2- und 3‑mal C3-Verletzungen. Die Verteilung nach Young und Burgess ergab: 9‑mal APC-I-, 18-mal APC-II-, 13-mal APC-III-, 9‑mal LC-I-, 3‑mal LC-II-, 2‑mal LC-III- und 10-mal VS-Verletzungen. Der mittlere Injury Severity Score (ISS) betrug 32 und die mittlere stationäre Verweildauer 29 Tage (pos. Korrelation p ≤ 0,001). Im Verlauf war eine radiologische Implantatlockerung bei 52 Patienten nachweisbar. Therapierelevante Komplikationen gab es in 14 Fällen. Hierbei war das Implantatversagen (n = 8) der Hauptgrund für eine operative Revision. Diskussion Obwohl die radiologische Implantatlockerung häufig beobachtet wird, ist sie nur selten Grund für einen Revisionseingriff. Kommt es hingegen zum vollständigen Implantatversagen, tritt dies meist innerhalb der ersten postoperativen Wochen auf und ist revisionsbedürftig. Eine frühzeitige Abklärung durch Röntgenbildgebung sollte bei Verdacht erfolgen. N2 - Background Separation of the pubic symphysis with corresponding diastasis can be stabilized by symphyseal plating. Objective Which pelvic injuries are stabilized with symphyseal plating and what is their outcome? Material and methods A retrospective evaluation of 64 patients who underwent symphyseal plating over a period of 24 months was conducted. Results Of the patients 56 were male and 8 female with a mean age of 44 years (SD ± 17 years). The main cause of the pelvic injuries were traffic accidents. The distribution according to the AO fracture classification was 14 × B1, 10 × B2, 5 × B3, 23 × C1, 9 × C2 and 3 × C3 injuries. The distribution according to the Young and Burgess classification showed 9 × APC I, 18 × APC II, 13 × APC III, 9 × LC I, 3 × LC II, 2 × LC III and 10 × VS injuries. The mean Injury Severity Score (ISS) was 32 (SD ± 17) and the mean inpatient stay was 29 days (SD ± 16 days; positive correlation p ≤ 0.001). Radiological implant loosening occurred in 52 patients. 14 patients required treatment for severe complications. The leading reason for revision surgery was implant failure (n = 8). Conclusion These observations suggest that radiological signs of implant loosening are commonly observed but rarely the reason for revision surgery. Complete implant failures, however; occur mainly within the first postoperative weeks and require early revision. A timely clarification by additional X-ray imaging should be carried out if this is suspected.

Severely injured patients are often in continuous need of intensive care and ventilator treatment. The question arises, whether restrictions related to COVID-19 have led to a decrease in severely injured patients and thus to an increase in intensive care unit (ICU) capacity. Material and methods A retrospective analysis of all seriously injured patients with an injury severity score (ISS) ≥16 was performed between 17 March and 30 April 2020 at a level 1 trauma center in Germany. The mechanism of injury and the ISS were recorded. Further data were collected as to whether it was a work-related accident, a documented suicide attempt and if surgery was necessary in the first 24 h after arrival in hospital. Data from 2018 and 2019 served as a control group. Results There was no substantial difference in the total number of seriously injured patients (2018 n = 30, 2019 n = 23, 2020 n = 27). Furthermore, there was no relevant difference in the number of patients needing intensive care or ventilator treatment when leaving the shock room. The number of patients needing an operative intervention within the first 24 h after arriving at hospital was slightly higher in 2020. The mean ISS was at a constant level during all 3 years. In 2020 there was no polytraumatized motorbike rider, who did not have a work-related accident (2018 n = 5, 2019 n = 4, 2020 n = 0). A noticeable increase in work-related accidents was observed (2018: 10%, 2019: 26.1%, 2020 44.4%). Discussion Restrictions related to COVID-19 did not lead to a reduction in seriously injured patients needing ICU care. Due to the monocentric data analysis there is room for misinterpretation. In general, intensive care and operating capacities should be managed with adequate consideration for seriously injured patients even in times of crisis, such as the COVID-19 pandemic. Confirmation through the German Trauma Register is pending.

We conducted a retrospective matched-pair analysis of data from a 10-year period from the multicenter database TraumaRegister DGU\(^®\) to analyze the impact of a concomitant femoral fracture on the outcome of TBI patients. A total of 4508 patients with moderate to critical TBI were included and matched by severity of TBI, American Society of Anesthesiologists (ASA) risk classification, initial Glasgow Coma Scale (GCS), age, and sex. Patients who suffered combined TBI and femoral fracture showed increased mortality and worse outcome at the time of discharge, a higher chance of multi-organ failure, and a rate of neurosurgical intervention. Especially those with moderate TBI showed enhanced in-hospital mortality when presenting with a concomitant femoral fracture (p = 0.037). The choice of fracture treatment (damage control orthopedics vs. early total care) did not impact mortality. In summary, patients with combined TBI and femoral fracture have higher mortality, more in-hospital complications, an increased need for neurosurgical intervention, and inferior outcome compared to patients with TBI solely. More investigations are needed to decipher the pathophysiological consequences of a long-bone fracture on the outcome after TBI.
