“…The first suggests that pain can develop over time as the result of gross motion at the os acromiale site. 17,28 The second proposes that the downward force generated by the deltoid attaching to an unstable acromion results in inferior displacement of the anterior portion of the os acromiale and impingement on the rotator cuff. 14 Recent studies have shown that musculoskeletal injuries leading to loss of practice time are common in women's competitive fast-pitch softball pitchers and that shoulder distraction stress and elbow extension torque before ball release are comparable to forces measured in baseball pitchers.…”

An os acromiale, an anatomical variant in which the acromion fails to undergo complete ossification, occurs in up to 8% of the population. 5,21 The os acromiale usually exists as a nonunion site, but in a small percentage of cases, there is an osseous connection with a cleft between the proximal fragment and the scapular spine. 21 Although individuals with os acromiale usually are asymptomatic, the literature contains case reports and limited case series of os acromiale causing shoulder pain. 2,3,14,18,20,22,24,28 The condition can be symptomatic secondary to pain at the pseudarthrosis site or from the mobile fragment impinging on the rotator cuff. 14,15,28 When nonoperative treatment fails to resolve the symptoms in these patients, surgical correction with internal fixation and bone grafting can be used successfully. 28

“…coracoacromiale, des acromialen Periosts und des Deltoideus kann bei kleinen OA durchgeführt werden [22]. Dies sollte allerdings nur dann erwogen werden, wenn keine Gefahr für eine Deltainsuffizienz besteht und ist somit für die am häufigsten vorkommenden Ossa mesoakromialia, deren Größe in etwa dem lateralen Klavikulaende entspricht, nicht geeignet.…”

“…Eine radikale Akromionresektion birgt die Gefahr der Deltainsuffizienz [20]. Hingegen können kleine Ossa mesoakromialia und alle Os praeakromialia mit gutem Ergebnis reseziert werden, wenn dabei de Insertion des Deltamuskels geschont oder sorgfältig rekonstruiert wird [4,22].…”

Section: ■ Resektionunclassified

“…Da die Mehrzahl der OA vom mesoakromialen Typ sind und deren Resektion den akromialen Gelenkteil des ACG komplett entfernen würde, tendieren die meisten Autoren bei einem instabilen OA zur Durchführung einer Fusion [4,13,22,24,29]. Die in der Literatur beschriebenen Techniken unterscheiden sich geringfügig, wollen aber alle eine Fusion in Kombination mit einer Aufrichtung des Akromions erreichen.…”

The optimal surgical treatment for symptomatic os acromiale that has failed nonoperative management is unclear in the literature. We conducted a systematic review of multiple medical databases for level I–IV evidence. Both radiographic and clinical outcomes were analyzed. Nine studies met the inclusion criteria (118 subjects, 125 shoulders). One hundred and fifteen subjects were treated surgically (122 shoulders). The mean age of the subjects was 49±11 years. The mean preoperative duration of symptoms was 12±8.6 months. Mesoacromiale was the most common type treated (94%). Internal fixation was the most common surgical technique used (60%), followed by excision (27%) and acromioplasty (13%). Rotator cuff repair was the most common concurrent surgical technique (performed in 59% of the surgically treated shoulders), followed by distal clavicle excision (25%). All surgical techniques resulted in improvement in clinical outcomes. Surgical management of symptomatic os acromiale that has failed nonoperative measures may predictably lead to improved outcomes.
