    Abstract: Purpose: Current guidelines on urgent thoracotomy of polytraumatized patients are based on data from perforating chest injuries. We aimed to identify predictive factors for urgent thoracotomy after chest-tube placement for blunt chest trauma in a civilian setting. Methods: Polytraumatized patients (Injury Severity Score ≥16) with blunt chest trauma, submitted to a level I trauma centre during a period of 12 years that received at least one chest tube were included. Trauma mechanism, chest-tube output, haemoglobin values, need for cellular blood products, coagulopathies, rib fracture pattern, thoracotomy, and mortality were retrospectively analysed. Results: 235 polytraumatized patients were included. Patients that received urgent thoracotomy (UT, n = 10) showed a higher mean chest-tube output within 24 h with a median (Mdn) of 3865 (IQR 2423–5156) mL compared to the group with no additional thoracic surgery (NT, n = 225) with Mdn 185 (IQR 50–463) mL (p 〈 0.001). The cut-off 24-h chest-tube output value for recommended thoracotomy was 1270 mL (ROC-Curve). UT showed an initial haemoglobin of Mdn 11.7 (IQR 9.2–14.3) g/dL and an INR value of Mdn 1.27 (IQR 1.11–1.69) as opposed to Mdn 12.3 (IQR 10–13.9) g/dL and Mdn 1.13 (IQR 1.05–1.34) in NT (haemoglobin: p = 0.786; INR: p = 0.215). There was an average number of 7.1(±3.4) rib fractures in UT and 6.7(±4.8) in NT (p = 0.649). Conclusions: Chest-tube output remains the single most important predictive factor for urgent thoracotomy also after blunt chest trauma. Patients with a chest-tube output of more than 1300 mL within 24 h after trauma should be considered for transfer to a level I trauma centre with standby thoracic surgery.

    Abstract: (1) Background: The treatment of proximal humeral fractures (PHFs) is debated controversially. Current clinical knowledge is mainly based on small single-center cohorts. The goal of this study was to evaluate the predictability of risk factors for complications after the treatment of a PHF in a large clinical cohort in a multicentric setting. (2) Methods: Clinical data of 4019 patients with PHFs were retrospectively collected from 9 participating hospitals. Risk factors for local complications of the affected shoulder were assessed using bi- and multivariate analyses. (3) Results: Fracture complexity with n = 3 or more fragments, cigarette smoking, age over 65 years, and female sex were identified as predictable individual risk factors for local complications after surgical therapy as well as the combination of female sex and smoking and the combination of age 65 years or older and ASA class 2 or higher. (4) Conclusion: Humeral head preserving reconstructive surgical therapy should critically be evaluated for patients with the risk factors abovementioned.

    Abstract: There is a lack of long-term data for minimally invasive acromioclavicular (AC) joint repair. Furthermore, it is not clear if good early clinical results can be maintained over time. The purpose of this study was to report long-term results of minimally invasive AC joint reconstruction (MINAR) and compare it to corresponding short-term data. Methods We assessed patients with a follow-up of at least five years after minimally invasive flip-button repair for high-grade AC joint dislocation. The clinical outcome was evaluated using the Constant score and a questionnaire. Ultrasound determined the coracoclavicular (CC) distance. Results of the current follow-up were compared to the short-term results of the same cohort. Results A total of 50 patients (three females, 47 males) were successfully followed up for a minimum of five years. The mean follow-up was 7.7 years (63 months to 132 months). The overall Constant score was 94.4 points (54 to 100) versus 97.7 points (83 to 100) for the contralateral side showing a significant difference for the operated shoulder (p = 0.013) The mean difference in the CC distance between the operated and the contralateral shoulder was 3.7 mm (0.2 to 7.8; p = 0.010). In total, 16% (n = 8) of patients showed recurrent instability. All these cases were performed within the first 16 months after introduction of this technique. A total of 84% (n = 42) of the patients were able to return to their previous occupations and sport activities. Comparison of short-term and long-term results revealed no significant difference for the Constant Score (p = 0.348) and the CC distance (p = 0.974). Conclusion The clinical outcome of MINAR is good to excellent after long-term follow-up and no significant differences were found compared to short-term results. We therefore suggest this is a reliable technique for surgical treatment of high-grade AC joint dislocation. Cite this article: Bone Joint J 2020;102-B(7):918–924.

    Abstract: Background and Objectives: The proximal humeral fracture (PHF) is one of the most common fractures in elderly patients. A PHF might influence the quality of life (QoL) on several different levels, especially in elderly patients, but it is unclear which treatment option results in a better QoL outcome. Therefore, we aimed to systematically review the current literature for studies that have analyzed the QoL and pain of elderly patients treated either surgically or non-operatively for PHF. Materials and Methods: A comprehensive search of the literature was performed in the PubMed database from January to April 2023. Studies describing the QoL or the level of pain of patients older than 60 years with the EuroQoL-5 Dimension (EQ-5D) score or the visual analogue scale (VAS) after the treatment of PHF, either non-operatively (non-OP), with open-reduction and internal fixation using a locking plate (LPF), or with reverse total shoulder arthroplasty (RTSA) were included. Twelve studies were analyzed descriptively and the individual risk of bias was assessed using the ROB2 and ROBINS-I tools. Results: A total of 12 studies with 712 patients at baseline were included (78% female sex, mean age 75.2 years). The reported VAS scores at 12-month follow-up (FU) ranged from 0.7 to 2.5. The calculated overall mean VAS score across all studies showed a decreasing tendency for all treatments, with an increasing FU time up to 12 months after PHF. None of the studies reported any significant differences of the EQ-5D across the groups. The overall calculated EQ-5D indices showed an increasing trend after 6–8 weeks FU, but did not differ significantly between the three treatments. Conclusions: In conclusion, the current literature suggests that there are no clinically important differences between the QoL or pain in elderly patients with PHF after non-operative treatment or surgical treatment with LPF or RTSA. However, the number of studies and level of evidence is rather low and further trials are urgently needed.

    Abstract: The purpose of this study was to analyze predictors of clinical outcomes of knotted versus knotless double-row self-reinforcing rotator cuff repairs of full-thickness rotator cuff tears with propensity score matching. Methods: Patients with arthroscopic repair of full-thickness rotator cuff tears involving the supraspinatus tendon using either a knotted or knotless linked, self-reinforcing double-row technique were included in the study. Preoperative subjective evaluation was performed using the ASES and SF-12 PCS scores. After a minimum two-year follow-up period, ASES and SF-12 PCS scores were collected again along with the SANE score, the QuickDASH score, and patient satisfaction. All data were collected prospectively and retrospectively reviewed. Postoperative ASES and SF-12 PCS scores were then modeled using inverse propensity score weighting in a multiple linear regression model (MLR) with multiple imputations. Age, sex, baseline ASES score, length of follow-up, number of anchors, worker’s compensation, previous cuff repair, and double-row repair technique (knotted or knotless) were the covariates used in this model. Results: 155 shoulders in 151 patients (109 men, 42 women; mean age at time of surgery 59±10 years) were eligible for inclusion. Outcomes data were available for 130 of 148 shoulders (87.8%) after exclusion of seven shoulders (4.5%) that underwent revision rotator cuff repair before final follow up (n=33/39 in the knotted group [84.6%]; n=97/109 [88.9%] in the knotless group).The mean follow-up was 2.9 years (range, 2.0-5.4 years). Overall, postoperative outcomes scores were significantly improved when compared to preoperative baselines (p 〈 0.05), with a median postoperative ASES score of 97 for the entire cohort. Our model showed that previous rotator cuff repair had a significant negative effect on postoperative ASES (β = -12.7, p 〈 0.001) and SF-12 PCS scores (β = -5.0, p = 0.036). A workers’ compensation claim (β = -10.6, p = 0.007) also had a significant negative effect on postoperative ASES scores. Higher baseline ASES score (β = +0.14, p = 0.025) positively influenced ASES outcomes. Use of a knotless technique also had a positive effect on postoperative scores (β = +2.5, p = 0.235). Age, gender, the length of follow-up and the numbers of anchors did not influence the outcomes (Table 1). Conclusion: Excellent clinical outcomes can be achieved a minimum of two years following arthroscopic repair of full-thickness rotator cuff tears using either the knotted or knotless linked double-row technique. Negative predictors of outcome include low preoperative ASES score, previous rotator cuff repair, and a workers’ compensation claim. Knotless double-row rotator cuff repair had a non-significantly positive effect on the postoperative ASES score compared to the knotted double-row suture bridge technique.

    Abstract: Hintergrund Die Versorgung der proximalen Humerusfraktur (PHF) ist komplex und verändert sich aufgrund neuer wissenschaftlicher Erkenntnisse dynamisch. Häufig werden in epidemiologischen Studien Daten präsentiert, die den demografischen Wandel und aktuelle Entwicklungen bei Implantatmaterial und Operationstechniken nicht miteinbeziehen. Das primäre Ziel dieser Studie war es, die Epidemiologie und Versorgungsrealität der PHF an einem Level-1-Traumazentrum mit schulterchirurgischem Schwerpunkt und die Veränderungen im Laufe eines Jahrzehnts zu evaluieren. Hypothesen 1. Zwischen den Zeiträumen von 2009 bis 2012 und 2014 bis 2017 zeigt sich eine Zunahme der Frakturkomplexität 2. In Korrelation mit der Komplexität steht die Anzahl an Nebenerkrankungen sowie die Häufigkeit der Osteoporose. Material und Methoden Von 2014 bis 2017 wurden 589 Patienten (73% weiblich; Durchschnittsalter 68,96 ± 14,9 Jahre) mit insgesamt 593 PHFs in diese retrospektive Studie eingeschlossen. Die Patientenakten, Röntgenbilder und CT-Untersuchungen aller Patienten wurden analysiert. Frakturen mit Ad-latus-Dislokation von 〈  0,5 cm und/oder einer Humeruskopfangulation von 〈  20° wurden als undisloziert klassifiziert. Patienten mit dislozierten Frakturen wurden in einen operativen Therapiealgorithmus eingeschlossen. Diese Ergebnisse wurden mit denen einer Kohorte von 2009 bis 2012 (n = 566) verglichen, die zu damaliger Zeit unter gleichen Kriterien eingeschlossen wurde. Ergebnisse Im entsprechenden Beobachtungszeitraum bestand ein vergleichbares Patientenkollektiv bez. Anzahl, Geschlechterverteilung und Alter. Dabei zeigte sich von 2009 bis 2012 im Vergleich zu 2014 bis 2017 eine Zunahme der 4-Part-Frakturen (20,4 zu 30%) bei gleichzeitiger Abnahme der 2-Part-Frakturen (13,9 zu 8,6%). In den Versorgungstechniken war bei Abnahme der konservativen Behandlung (27,8 zu 20,6%), der Nagelosteosynthese (10,7 zu 2,7%) und der anatomischen Prothese (5,4 zu 1%) eine gleichzeitige Zunahme der winkelstabilen Plattenosteosynthese (43,2 zu 56,7%) und der inversen Schulterprothese (9 zu 18,4%) erkennbar. Insgesamt konnte von 2009 bis 2012 zu 2014 bis 2017 eine Zunahme der operativen Versorgung (72,2 zu 79,4%) festgestellt werden. Es zeigte sich im zeitlichen Verlauf eine Zunahme der vorbekannten Osteoporoseinzidenz (13 zu 20,6%) sowie eine Häufung an Nebenerkrankungen bei 3- und 4-Part-Frakturen. Schlussfolgerung Bei gleicher Beobachtungsdauer zeigt sich in einem spezialisierten Schulterzentrum von 2009 bis 2012 auf 2014 bis 2017 neben einer Zunahme der operativ behandelten Frakturen eine Steigerung der Komplexität der versorgten Verletzungen. Zudem kann man eine Zunahme an Osteoporose sowie eine Häufung an Nebenerkrankungen bei 3- und 4-Part-Frakturen beobachten. Als Folge der zunehmenden Komplexität wurden neben neuen Implantaten (PEEK, fenestrierte Schrauben zur Zementaugmentation) neue operative Techniken entwickelt (DPO). Als Konsequenz der zunehmenden Komplexität und der gesteigerten Osteoporosehäufigkeit zeigt sich eine Zunahme der inversen Schulterprothetik bei proximalen Humerusfrakturen.
