TY - THES A1 - Reder, Christiane T1 - Die inverse Schulterprothese nach fehlgeschlagener Versorgung proximaler Humerusfrakturen T1 - Reverse Total Shoulder Arthroplasty after failed treatment of fractures of the proximal humerus N2 - Im König-Ludwig-Haus wurde im Zeitraum von 2001 bis 2006 bei 65 Patienten nach fehlgeschlagener Versorgung einer proximalen Humerusfraktur eine inverse Prothese implantiert. Davon konnten 46 Patienten nachuntersucht werden. Vorbehandelt waren die Patienten zu 39,1% (n=18) konservativ, zu 26,1% (n=12) mit winkelstabiler Platte, zu 4,3% (n=2) mit proximalem Humerusnagel, zu 10,9% (n=5) mit Drähten, zu 6,6% (n=3) mit Drähten und Schrauben und zu 8,7% (n=4) mit Schrauben. Bei 4,3% (n=2) wurde eine Humeruskopfresektion durchgeführt. Das durchschnittliche Alter der Patienten lag bei 73,9 Jahren. 28,2% (n=13) waren männlich, 71,1% (n=33) waren weiblich. Im Mittel erreichten die Patienten postoperativ einen Constant Score von 45 Punkten. Bereinigt nach Alter und Geschlecht ergibt das 64 % des altersentsprechenden Normwertes. Minimalinvasiv mit Schrauben bzw. Schrauben und Draht versorgte Patienten zeigten die besten Ergebnisse mit durchschnittlich 55,3 bzw. 56,7 Punkten. 9 Patienten gaben an mit dem Ergebnis der TEP-Implantation sehr zufrieden zu sein, 37 waren zufrieden. Lediglich zwei Patienten waren unzufrieden mit dem postoperativen Ergebnis, wobei diese nicht dazu bereit waren, weitere Auskünfte zu geben. Auch aus den Krankenakten waren die Gründe hierfür nicht ersichtlich. Neben zwei periprothetischen Frakturen nach erneutem Sturzereignis trat lediglich eine Abszedierung nach Schweissdrüsenabszess als Komplikation auf. Die inverse Schulterprothese stellt somit eine gute Möglichkeit der Versorgung nach fehlgeschlagenen Voroperationen bei proximaler Humerusfraktur dar. Damit ist zwar eine Verbesserung der Funktion und hohe Zufriedenheit unter den Patienten zu erzielen, jedoch sind die funktionellen Ergebnisse deutlich schlechter als bei primärer TEP-Implantation bei Defektarthropathie. Mögliche Gründe hierfür waren operationsbedingte Morbidität und Deltaatrophien aufgrund des Operationszugangs bei osteosynthetischer Versorgung N2 - In the period from 2001 to 2006 in König-Ludwig-Haus reverse total shoulder arthroplasty in 65 patients after failed supply a proximal humerus fracture was implanted. Of these 46 patients could be followed up. 39.1% (n = 18) of these were pertreated conservative, 26.1% (n = 12) with plat, 4.3% (n = 2) with a nail, 10.9% (n = 5) with wires, 6.6% (n = 3) with wires and screws and 8.7% (n = 4) with screws. The average age of the patients was 73.9 years. 28.2% (n = 13) were male, 71.1% (n = 33) were female. On average, the patients achieved an postoperative Constant score of 45 points. Adjusted for age and sex is 64% of age-matched normal range. Minimally invasive supplied with screws or bolts and wire patients showed the best results with an average of 55.3 and 56.7 points. 9 patients reported being very satisfied with the results of the implantation, 37 were satisfied. Only two patients were dissatisfied with the postoperative results, which were not prepared to provide further information. The reverse shoulder prosthesis is thus a good way of care after failed previous surgery with proximal humerus fractures represent thus an improvement of function and high satisfaction among patients is to achieve, but the functional results clearly worse than in primary TEP implantation in arthropathy.

Staged reverse shoulder arthroplasty (RSA) with temporary implantation of an antibiotic-loaded spacer is widely accepted but still discussed controversially. This study investigated the shoulder-specific bacterial spectrum, infection control rate, functional outcome, and infection-free survival rate after staged RSA in the mid- to long-term follow-up. It was hypothesized that staged RSA would show a high infection-free survival rate. Methods A total of 39 patients treated with staged RSA for primary septic arthritis (n = 8), secondary infection (n = 8), or periprosthetic infection (n = 23) were retrospectively included. The infection control rate was calculated based on cultures taken intraoperatively at spacer removal and RSA implantation. Infection-free survival was defined as no revision due to infection. The minimum follow-up period for functional outcome assessment was 2 years (n = 14; mean, 76 months; range, 31-128 months). Results Cutibacterium (26%) and coagulase-negative staphylococci (23%) were the predominant pathogens. The infection control rate was 90%. The cumulative infection-free survival rate was 91% after 128 months. Follow-up examinations showed a mean Constant score of 48 (range, 7-85), a mean QuickDASH (short version of Disabilities of the Arm, Shoulder and Hand questionnaire) score of 40.0 (range, 11.4-93.3), and a mean pain score of 1.6 (range, 0-7). Conclusion Staged RSA implantation was confirmed to be a reliable treatment option for primary, secondary, and periprosthetic infections of the shoulder. The infection control rate and infection-free survival rate are satisfactory. However, patients and surgeons must be aware of functional impairment even after successful treatment of infections.

This study evaluates the functional outcome and the different prosthetic treatment options for chronic locked dislocations of the glenohumeral joint and a subclassification is proposed. Methods In this single-center retrospective case series, all patients with a chronic locked dislocation treated surgically during a four-year period were analyzed. Constant score (CS), Quick Disabilities of Shoulder and Hand Score (DASH), patient satisfaction (subjective shoulder value (SSV)), revision rate and glenoid notching were analyzed. Results 26 patients presented a chronic locked dislocation of the glenohumeral joint. 16 patients (62%) with a mean age of 75 [61-83] years were available for follow-up at 24 ± 18 months. CS improved significantly from 10 ± 6 points to 58 ± 21 points (p < 0.0001). At the final follow-up, the mean DASH was 27 ± 23 and the mean SSV was 58 ± 23 points. The complication rate was 19% and the revision rate was 6%; implant survival was 94%. Scapular notching occurred in 2 (13%) cases (all grade 1). Conclusion With good preoperative planning and by using the adequate surgical technique, good clinical short-term results with a low revision rate can be achieved. The authors suggest extending the Boileau classification for fracture sequelae type 2 and recommend using a modified classification to facilitate the choice of treatment as the suggested classification system includes locked posterior and anterior dislocations with and without glenoid bone loss.
