    Abstract Aim: Arthrodesis of the shoulder joint is a radical event, so it is difficult to explain its significance to patients. It has been the last resort in hopeless cases. Knowledge of long-term results and evaluation of advantages and disadvantages seems to be helpful in this regard.
    Methods: Eleven patients with mean age of 45 (31 - 58) years were operated between 2000 and 2013. All patients could be included in the investigation (FU mean 8.5 [3 - 16] years; 8 male and 3 female; right 9, left 2). Patients had the following indications: persistent instability 5 (2 with epilepsy), rotator cuff rupture 2 (1× after combined latissimus dorsi and teres major transfer), brachial plexus injury/defect 2, locked dislocation 1 and posttraumatic arthropathy 1. Fixation with DC plate (pre-bent to 110°) was used in all cases; with special focus on placing at least one screw in the scapular neck. The targeted arthrodesis position was abduction 30°, forward flexion 30°, and internal rotation 30°.
    Results: Active abduction improved from 12 to 63°, forward flexion from 21 to 79° and internal rotation from 10 to 47° (mean values). In the resting position with hanging arm aside, mean abduction was 3° and forward flexion 8°. Nine of 11 patients had considerable relief of pain, from 8.3 to 2.4 points VAS. Five patients rated the outcome as excellent, 3 as good and 1 as satisfactory. Nine patients would repeat the procedure. In summary, an Oxford Shoulder Score of 31.6 points was achieved, and SSV of 58%. Bony fusion was achieved in all cases, 3 - 4 months p. o. in mean. There were no important neurological or angiological complications.
    Conclusions: Plate arthrodesis in the technique used achieves high fusion and a low complication rate. Relief of pain and functional improvement are astonishing. Analysis of our results indicates that correction of the positions mentioned above is necessary: i. o. arthrodesis position for abduction 25° (by means of pre-bending plate of 105°), forward flexion 20° and internal rotation 30° are suggested.

    Abstract Background: Irreparable posterosuperior rotator cuff tears are treated in several ways. Transfer of the latissimus dorsi is an alternative with acceptable mid-term results, but long-term results have rarely been published.
    Methods: The cases of 108 consecutive patients with 115 shoulders treated with latissimus dorsi transfer between 2000 and 2005 were reviewed clinically and radiographically. Ninety-three shoulders in eighty-six patients were included in the follow-up analysis. The mean duration of follow-up was 9.3 years (range, 6.6 to 11.7 years), and the mean age at the operation was fifty-six years (range, forty to seventy-two years). Outcome measures included the Constant-Murley score (Constant score), American Shoulder and Elbow Surgeons (ASES) index, and visual analog scale (VAS) for pain. The progress of cuff tear arthropathy was determined with radiographic evaluation according to the system described by Hamada et al.
    Results: The mean relative Constant score improved from 44% preoperatively to 71% at the time of follow-up (p < 0.0001, effect size = 0.6), excluding the clinical failures. Similarly, the mean ASES index improved from 30 to 70 (p < 0.0001, effect size = 0.7), and the mean VAS score decreased from 7.8 to 2.4 (p < 0.0001, effect size = 0.8). A pain-free outcome was reported in only eighteen shoulders (19%). Active shoulder movement improved significantly (p < 0.05). The mean Hamada radiographic grade of cuff tear arthropathy increased from 1.7 (range, 0 to 2) preoperatively to 2.2 (range, 1 to 5) (p < 0.0001, effect size = 0.2). The rate of clinical failure of latissimus dorsi transfer was 10%, and the rate of shoulder prosthetic replacement after latissimus dorsi transfer was 4%.
    Conclusions: Pain relief and improvement of shoulder function were maintained a mean of 9.3 years after latissimus dorsi transfer for irreparable posterosuperior cuff defects. The younger the patient, the better the outcome.

Gelegentlich stellt dieses Verfahren aber in problematischen Fällen die letzte Möglichkeit dar. Das Wissen um die Langzeitergebnisse kann deshalb bei der Erläuterung der Vor- und Nachteile dieser Methode dem Patienten gegenüber von erheblichem Nutzen sein.
    Methodik: Im Zeitraum von November 2000 bis August 2013 wurden 11 Patienten mit einer Schulterarthrodese versorgt, die bei einer mittleren Nachuntersuchungszeit von 8,5 (3 – 16) Jahren alle nachuntersucht werden konnten (8 Männer, 3 Frauen; rechts 9-mal, links 2-mal, Durchschnittsalter 45 [31 – 58] Jahre). Die Indikation zu dem Eingriff wurde 5-mal wegen einer nicht beherrschbaren und mehrfach voroperierten Instabilität gestellt (davon 2-mal bei Epilepsie), 2-mal wegen einer Rotatorenmanschettendefektarthropathie (davon einmal bei Z. n. kombiniertem Latissimus-dorsi- und Teres-major-Transfer), 2-mal wegen einer oberen Plexusläsion, einmal wegen einer persistierenden Luxation und einmal wegen einer posttraumatischen Defektarthropathie. Alle OPs erfolgten mittels der AO-Technik (8-mal Zweischnittzugang, 3-mal Einschnittzugang), d. h. Fixation mittels einer schmalen DC-Platte, die im Mittel auf 110° vorgebogen wurde. Besonderer Wert wurde bei der Fixation auf die Platzierung einer, besser von 2 von kranial durch die Platte geführten Schrauben im Skapulahals gelegt. Intraoperativ wurde eine Armposition von Abduktion/Anteversion/Innenrotation 30/30/20 angestrebt.
    Ergebnisse: Durch den Eingriff wurde eine deutliche Verbesserung der aktiven Beweglichkeit erreicht, von 12 auf 63° für die Abduktion, von 21 auf 79° für die Anteversion und von 10 auf 47° für die Innenrotation (Mittelwerte). In Ruheposition hing der Arm locker entspannt mit 3° Abduktion und 8° Anteversion am Körper herab. Neun der 11 Patienten waren zufrieden bzw. sehr zufrieden und würden den Eingriff wiederholen lassen. Die Schmerzlinderung verbesserte sich auf der VAS von 8,3 auf 2,4 Punkte. Im Oxford Shoulder Score wurden 31,6 Punkte erreicht und im Simple Shoulder Value 58%. Röntgenologisch waren alle Arthrodesen nach 3 – 4 Monaten knöchern durchgebaut. An Komplikationen ist eine Fehlstellung mit postoperativer subkapitaler Korrekturosteotomie zu nennen. Relevante neurologische oder Gefäßkomplikationen traten nicht auf.
    Schlussfolgerungen: Es handelt sich bei der beschriebenen Technik um eine sichere und reproduzierbare OP-Technik mit hoher Ausheilungs- und erstaunlich geringer Komplikationsrate. Schmerzlinderung und Funktionsverbesserung sind enorm, wobei die Zufriedenheit der Patienten von der Ausgangslage abhängt – die Patienten mit den präoperativ stärksten Schmerzen waren am zufriedensten. In Auswertung unserer Ergebnisse ist eine Korrektur der o. g. Empfehlungen für die Arthrodesenposition erforderlich: Abduktion 25° (mittels der auf 105° vorgebogenen Platte), Anteversion von 20° und Innenrotation von 30°.

    Abstract Background and purpose: Reversed shoulder arthroplasty may be used for severe arthropathy where conventional prostheses cannot restore the function sufficiently. We analyzed the medium-term results and potential complications of the reversed prostheses, and also the influence of etiology on the result. METHODS; 52 women and 7 men, average age 70 (60-82) years, were followed for mean 4 (2-7) years. The indications were cuff tear arthropathy (CTA) (23), fracture sequelae (20), and revision of a failed conventional arthroplasty (16).
    Results: The average Constant score improved from 18 (2-55) points to 59 (17-96) points. It rose from 26 to 74 points in patients with CTA, from 12 to 48 in those with fracture sequelae, and from 10 to 54 points in revision arthroplasty. We also found an overall improvement in active forward flexion from 47 degrees to 105 degrees , and in active abduction from 46 degrees to 93 degrees . Scapular notching was seen in 51 shoulders. Radiolucent lines below the base-plate were present in 2 cases. There were no instances of loosening. Revisions were necessary in 15 patients: 5 with infections (all had had prior surgery), 5 with hematoma, 3 with dislocations, and 2 with disconnections of the shaft components.
    Interpretation: Reversed prosthetic replacement is a suitable method for restoring function and attaining pain relief in severe arthropathies. The results in revision arthroplasty are less predictable, with complications and revision rates higher than those in CTA patients. The reversed prosthesis should therefore only be used when conventional methods have failed.

    Abstract Objectives: Arthroplasty for the proximal humerus problems secondary to fractures is troublesome, because of necrosis of the tubercles and the resulting insufficiency of the rotator cuff. The aim of this study was to investigate whether better results can be achieved with the differential use of anatomic and reverse shoulder prostheses, in comparison to the preoperative status.
    Methods: Fifty-five patients with secondary fracture prostheses due to sequelae of fractures of the humeral head were followed. Anatomic prostheses were implanted in 36 cases (fracture sequelae types 1 and 2 according to Boileau), and reversed prostheses were implanted in 19 cases (fracture sequelae types 3 and 4).
    Results: The mean scores of the patients improved from 19 to 68 points (anatomic prosthesis) for fracture sequelae types 1 and 2, and from 9 to 47.5 points (reverse prosthesis) for fracture sequelae types 3 and 4.
    Conclusion: The differential use of anatomic and reversed shoulder prostheses in secondary fracture treatment leads to an improvement in postoperative results. In fracture sequelae types 1 and 2, the anatomic prosthesis is a better choice. However, in fracture sequelae types 3 and 4 with severe deformities, the reversed prosthesis is clearly superior to the anatomic prosthesis.
