Abstract

ÖZET
Amaç: Bir Türk popülasyonunda akromiyon tipi, os acromiale prevalansını ve akromion tipolojisinin subakromiyal
mesafe ile ilişkisini belirlemek.
Gereç ve Yöntem: Dahil etme kriterlerini karşılayan toplam 528 hasta, os akromiale varlığı, akromiyon tipi
ve subakromial mesafe açısından iki radyolog tarafından değerlendirildi. Akromion tipolojisi, os akromiale
olmayan hastalarda değerlendirildi. Os akromion, subakromial mesafedeki değişiklikler istatistiksel olarak
cinsiyet, etkilenen taraf (sağ / sol) varlığına bağlı olarak değerlendirildi. Ayrıca, subakromial mesafe ile akromion
türleri arasındaki ilişki araştırıldı.
Bulgular: On iki hastada (% 2.27) os akromiale vardı. Yüz on altı hastada tip I akromion (% 22.5) varken, 352
hastada tip II akromion (% 68.2), 10 hastada tip III akromion (% 1.9) ve 38 hastada da tip IV akromion (% 7.4)
vardı. Ortalama subakromial mesafe 6.6 mm (% 95; 6.5-6.77 mm) olarak bulundu. Akromion tipine göre,
subakromial mesafe tip IV akromionda tip I ve II'ye göre anlamlı derecede yüksekti (p = 0.02). Subakromial
mesafede cinsiyet ve taraf açısından anlamlı fark yoktu (sırasıyla p = 0.309 ve 0.454).
Sonuç: Türk popülasyonunda cinsiyete ve tarafa göre subakromial mesafede anlamlı bir fark yoktu. Değerlendirilen
Türk popülasyonunda en sık ve en yaygın akromion türü sırasıyla tip II ve tip III idi. Subakromiyal
mesafe tip 4 akromionda daha büyüktü.
Anahtar Kelimeler: Os acromiale; Subacromial mesafe; Acromion tipoloji
ABSTRACT
Purpose: To determine the prevalence of acromion type, os acromiale, and the relation of acromion
typology with subacromial distance in a Turkish population.
Materials and Methods: A total of 528 patients who met the inclusion criteria were evaluated in terms
of presence of os acromiale, type of acromion, and subacromial distance by two radiologists. Acromion
typology was evaluated in patients without os acromiale. Variations of subacromial distance depending
on the presence of os acromion, sex, affected side (right / left) were statistically assessed. In addition, an
association between subacromial distance and acromion types was sought.
Results: Twelve patients (2.27%) had os acromiale. One-hundred and sixteen patients had type I acromion
(22.5%) whereas 352 had type II acromion (68.2%), 10 had type III acromion (1.9%), and 38 had type IV
acromion (7.4%). The median subacromial distance was found to be 6.6 mm (95% CI for median; 6.5-6.77
mm). Regarding the acromion type, subacromial distance was significantly higher in type IV acromion than
in types I and II (p= 0.02). There was no significant difference in subacromial distance according to sex and
side (p=0.309 and 0.454 respectively).
Conclusion: There was no significant difference in subacromial distance according to sex and side in the
Turkish population. The most and least common types of acromion in the evaluated Turkish population
were type II and type III, respectively. The subacromial distance was greater in type 4 acromion.
Key Words: Os Acromiale; Subacromial distance; Acromion typology
