    It Is Always the Same—A Complication Classification following Angular Stable Plating of Proximal Humeral Fractures

    by Georg Siebenbürger, Rouven Neudeck, Mark Philipp Daferner, Evi Fleischhacker, Wolfgang Böcker, Ben Ockert, Tobias Helfen

    Introduction: The aim of this study was to create a novel complication classification for osteosynthesis-related complications following angular stable plating of the proximal humerus subsuming the influence of these complications on clinical outcome in relation to fracture morphology and consequent revision strategies. A total of 1047 proximal humerus fractures with overall 193 osteosynthesis-associated complications (24.5%) were included. The following complication types could be clarified: complication Type 1 is defined by mild varus (<20°) or valgus displacement of the humeral head without resulting in a screw cutout through the humeral head cortex. Type 2a is defined by varus displacement (20°) of the humeral head with screw cutout at the humeral head cortex. Complication Type 3 describes a displacement of the angular stable plate in the humeral shaft region with associated shaft-sided screw cutout, while the position of the humeral head remains static. Complication Type 4 is characterized by the occurrence of AVN with or without glenoidal affection (4a/b). Clinical outcome according to the constant score was mainly affected by type 2–4, leading to a deteriorated result. Depending on the type of complication, specific revision strategies can be considered. Additionally, more complex fracture patterns fostered the incidence of complications.

    The Influence of Adherence to Orthosis and Physiotherapy Protocol on Functional Outcome after Proximal Humeral Fracture in the Elderly

    by Evi Fleischhacker, Johannes Gleich, Vera Smolka, Carl Neuerburg, Wolfgang Böcker, Tobias Helfen

    In the treatment of proximal humeral fractures (PHF), patients are often recommended to wear a sling or orthosis and to perform physiotherapy. However, some patients, especially elderly ones, struggle to comply with these rehabilitation regimens. Therefore, the aim of the study was to evaluate whether these incompliant patients have a worse functional outcome than those who adhere to the rehabilitation protocol. After receiving a diagnosis of a PHF, patients were divided into four groups according to fracture morphology: conservative with sling, operative with sling, conservative with abduction orthosis, and operative with abduction orthosis. At the 6-week follow-up, compliance regarding brace use and physiotherapy performance were assessed, as well as the constant score (CS) and complications or revision surgeries. The CS as well as the complications and revision surgeries were also surveyed after one year. In 149 participants, with a mean age of 73.9 ± 7.2 years, only 37% terminated orthosis and only 49% underwent physiotherapy as recommended. The statistical analysis showed no significant difference in the CS, complications, and revision surgeries between the groups.

    The Accuracy of Distal Clavicle Fracture Classifications—Do We Need an Amendment to Imaging Modalities or Fracture Typing?

    by Evi Fleischhacker, Georg Siebenbürger, Johannes Gleich, Wolfgang Böcker, Fabian Gilbert, Tobias Helfen

    Background: Despite its fair-to-moderate reliability, the “modified Neer classification” is widely accepted and used. The purpose of this study was to reevaluate its applicability. Methods: Of n = 59 patients with distal clavicle fractures, fractures were classified on standard radiographs. Afterwards, an MRI examination was performed, and fractures reclassified. The primary outcome parameter was quantifying the rate of misclassification. The secondary outcome parameters were the evaluation of the ligamentous injury constellations. Results: In all cases, the fracture course and ligamental integrity could be assigned to the fracture type. Correction of the classification was necessary in n = 5 (8.5%) cases. In n = 3 (5%) cases, a correction was necessary from Neer I to Craig IIc and thus from conservative to operative treatment. Mean coracoclavicular distance (CCD) in Neer I was 10.2 ± 2.1 mm versus 14.2 ± 3.9 mm in Craig IIc (p = 0.02). The mean fracture angle in Neer I was 25.1 ± 3.3° versus 36.8 ± 4.4° in Craig IIc (p = 0.02). Conclusion: Cross-sectional imaging resulted in higher precision. Nevertheless, recommendations remain for standard radiographs. The CCD and fracture angle should be considered. An angle of >30° can be assumed as a parameter of instability. A previously undescribed fracture type does not seem to exist. The modified Neer classification is an appropriate and complete fracture classification.


  • Einfluss der Klinikgröße auf die Einleitung einer Osteoporosetherapie bei alterstraumatologischen Patient*innen mit proximaler Femurfraktur

    by Evi Fleischhacker, J Gleich, K Rascher, C Schöneberg, M Knobe, Wolfgang Böcker, Christian Kammerlander, Carl Neuerburg

    Einleitung Eine Vielzahl der alterstraumatologischen Patient*innen die mit proximaler Femurfraktur in einer unfallchirurgischen Abteilung behandelt werden, haben eine verminderte Knochendichte und nicht selten eine manifeste Osteoporose, welche bis dato unerkannt und untherapiert ist. Entscheidend in der Prävention zukünftiger Frakturen ist also die Einleitung einer Osteoporosetherapie bei diesen Patient*innen, welche maßgeblich von der Sensibilisierung der Unfallchirurg*innen in den behandelnden Kliniken abhängt. In der vorliegende Registerstudie wurde ausgewertet, ob die Einleitung einer Osteoporosetherapie von der Klinikgröße abhängig ist. Methode Im AltersTraumaRegister DGU werden alle Patient*innen ≥ 70 Jahre erfasst, die nach hüftgelenknaher Femurfraktur in einem zertifizierten AltersTraumaZentrum DGU​ operativ versorgt wurden. Es erfolgte die retrospektive Analyse der Jahrgänge 2016-2019 unter Ausschluss von Patient*innen mit periprothetischen Frakturen. Durch Abgleich mit dem Traumaregister DGU wurde ermittelt, ob Patient*innen an einem überregionalen oder lokalen/regionalen Traumazentrum versorgt wurden und dies zur Gruppendefinition herangezogen. Die Bereitstellung der Daten erfolgte durch das AltersTraumaRegister DGU. Auswertung und Interpretation liegen in der Verantwortung des Autors und haben den abschließenden Reviewprozess des AltersTraumaRegister DGU noch nicht durchlaufen (ATR-DGU-Projekt-ID: 2020-008). Ergebnisse Insgesamt wurden 19712 Patient*innen mit einem Durchschnittsalter von 85 Jahren (IQR 80; 89) eingeschlossen. 5636 Patient*innen wurden an 19 überregionalen (ÜTZ), 14076 Patient*innen an 61 lokalen/regionalen Traumazentren (LRTZ) versorgt; es zeigte sich kein signifikanter Unterschied bei Alter, Geschlecht und ASA-Score der beiden Gruppen. An ÜTZ hatten bei Aufnahme bereits 24% der Patient*innen eine Osteoporosetherapie, an LRTZ nur 18,3% (p<0,001); am 7. postoperativen Tag erhielten an ÜTZ 72,4% der Patient*innen, an LRTZ 62,8% eine Osteoporosetherapie (p<0,001). Diskussion In der vorliegenden Studie konnte an einem standardisiert erfassten und behandelten Kollektiv alterstraumatologischer Patient*innen gezeigt werden, dass die Größe der versorgenden Klinik Einfluss auf die Einleitung der Osteoporosetherapie alterstraumatologischer Hüftfrakturpatienten hat. Diese Beobachtung kann sowohl durch die Klinikstruktur (z.B. Mitbehandlung durch Endokrinologen, Zentrenbildung, Fracture Liaison services), als auch durch das zugewiesene Patientenklientel (Unterversorgung der Patient*innen durch Hausärztemangel etc.) bedingt sein und bleibt von hoher Relevanz für zukünftige Studien.
