“…2,7 A retrospective study by Cheung et al discussed previous open shoulder operations as a risk factor for instability after RTSA, acting as a leading cause of required reoperations. 4 The findings from our review with respect to increased complication rates in revision scenarios are in agreement with those by Cheung et al 4 Additionally, in this review, complication rates varied greatly. The variation in rates could partly be explained by the definition of a complication.…”

“…These patients underwent revision with a metallic spacer and a thicker polyethylene liner resulting in "restoration of contralateral humeral length and a stable shoulder" though no specific outcome measures for this sub-cohort of patients were included [33]. Cheung et al also demonstrated good patient satisfaction and moderate to good post-operative ASES scores in 5 patients who underwent revision RSA with polyethylene exchange [11].…”

“…Instability after RSA is the most common complication of RSA with reported incidence ranging from 0.5 to 9% [11,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. The initial evaluation for an unstable RSA is an appropriate history, physical examination, and radiographic analysis, including full-length humeral radiographs to evaluate for humeral shortening [13••].…”

“…The relative risk of post-operative dislocation has been reported to be 1.90 [95% CI 1.61-2.23] after RSA in patients with an irreparable subscapularis tendon compared with those with a repaired tendon [25]. Most recently, Cheung et al showed that successful subscapularis repair was independently associated with a decreased odds of postoperative instability 2 years after RSA [11]. Continued analysis of the role of the subscapularis tendon is required given the significant controversy that remains in the literature.…”

Purpose of Review The most common complications warranting revision consideration in reverse shoulder arthroplasty (RSA) include instability and its associated causes: infection, periprosthetic fracture, and glenoid baseplate loosening. Management of complications can be challenging and the nuances of treatment are still being elucidated. The focus of this paper is to review the treatment of the failed RSA and discuss evidence-based recommendations for revision. Recent Findings The most common complications requiring revision RSA are instability and infection. The causes for instability can be subdivided into three main subcategories: loss of compression, loss of containment, and impingement. Loss of compression is further broken down into 6 subcategories revolving around abnormal prosthesis positioning, undersized prostheses, or intrinsic soft-tissue tension loss leading to instability. Periprosthetic infection can also lead to instability, yet the most appropriate management for infected RSA remains controversial. Summary Restoring stability by maximizing deltoid and soft tissue tension while avoiding impingement revolves around three basic methods: (1) lateralizing and/or upsizing the glenosphere to an inferior position on the glenoid, (2) use of a more constrained polyethylene insert, and (3) distalizing the humerus by increasing the polyethylene thickness and/or the thickness of the humeral tray. Management of periprosthetic joint infection can be performed in one-stage, two-stage, or "three-stage" procedures all showing good outcomes with two-stage procedures being the most commonly performed. However, persistent positive culture with propriobacterium acnes can occur in up to 25% of cases. In order to limit the associated morbidity from failed revision reverse shoulder arthroplasty, continued research on best management of associated complications is warranted.

“…Dabei wird über bessere Ergebnisse in der aktiven Außenrotation nach Refixation und Einheilung der Tuberkula in nahezu anatomischer Position am proximalen Schaft berichtet [2][3][4]. Auch die Häufigkeit von Luxationen wird bei refixierten Tuberkula reduziert [5]. Deshalb wird ein Verfahren der Refixation der Tuberkula für eine speziell zur Frakturversorgung entwickelte inverse Frakturprothese vorgestellt [6].…”
