Cavitas Glenoidalis Morfolojisinin Kuru Kemikler Üzerinde İncelenmesi

Abstract

Amaç: Bu çalışmanın amacı, cavitas glenoidalis (CG) çentik ve şekil varyasyonlarını ortaya koymak, klinik önemini vurgulamak ve daha önceki çalışmalarla karşılaştırmaktır. Gereç ve Yöntemler: Bu çalışma, erişkin Anadolu popülasyonuna ait 157 (78 sağ taraf, 79 sol taraf) kuru scapula ile yapıldı. CG'ler oval, armut ve ters virgül şeklinde tiplendirildi ve CG çentik sayısı not edildi. Bulgular: En sık görülen CG şekli, sağ tarafta 63 (%80,8), sol tarafta 49 (%62) ve toplamda 112 (%71,4) ile armut şeklinde CG olarak bulundu. İkinci sıklıktaki CG şekli ise sağ tarafta 13 (%16,6), sol tarafta 28 (%35,5) ve toplamda 41 (%26,1) ile oval şekilli CG olarak bulundu. Glenoid çentik sağ taraf, sol taraf ve toplamda sırası ile 28 (%35,9), 19 (%24,1) ve 47 (%29,9) olarak tespit edildi. Ters virgül şekilli CG'lerin tamamında belirgin glenoid çentik varken oval şekilli CG'lerde ise yoktu. Armut şekilli CG’lerde belli belirsiz glenoid çentik vardı veya hiç glenoid çentik yoktu. Armut şekilli CG’de glenoid çentik sağ taraf, sol taraf ve toplamda sırası ile 26 (%41,3), 17 (%34,7) ve 43 (%38,4) olarak tespit edildi. Sonuç: Bu çalışmada en sık (%71,4) armut şekilli CG bulunmuştur. Scapulaların 47 (%29,9) tanesinde glenoid çentik vardı. CG'nin çentik ve şekil varyasyonları önemlidir ve bu çalışmanın anatomistler, ortopedistler ve radyologlara bu açıdan katkıda bulunacağı düşünülmektedir.

Morphologic Evaluation of the Glenoid Cavity on Dry Scapula

Abstract

Aim: The aim of this study was to determine the notch and shape variations of the glenoid cavity (GC), to emphasize its clinical importance, and compare it with the previous studies. Material and Methods: This study was performed with 157 (78 right sides, 79 left sides) adult Anatolian dry scapulae. The GCs were typed as oval, pear, and inverted comma shaped and noted the number of GC notch. Results: The most common GC shape was found as the pear shaped with 63 (80.8%) at the right side, 49 (62%) at the left side, and 112 (71.4%) in total. The second most common GC shape was found as oval shaped with 13 (16.6%) at the right side, 28 (35.5%) at the left side, and 41 (26.1%) in total. The glenoid notch was found at the right side, left side, and totally; 28 (35.9%), 19 (24.1%), and 47 (29.9%), respectively. All of the inverted comma shaped GCs had distinct glenoid notch, while the oval shaped GCs not. The pear shaped GCs had indistinct glenoid notch or no glenoid notch. The glenoid notch was found at the right side, left side, and totally on the pear shaped GC; 26 (41.3%), 17 (34.7%), and 43 (38.4%), respectively. Conclusion: Pear shaped GC was found as the most (71.4%) common shape in this study. Forty-seven (29.9%) of the scapulae had a glenoid notch. The notch and shape variations of the GC are important and this study will contribute to anatomists, orthopedists, and radiologists from this perspective.
