Abstract

Aim: The aim of this study was to investigate whether the frequency of palmaris longus (PL) absence in Somali population differed from other populations in Africa and the rest of the world and to evaluate its association with sex and side of the limb involved.

Methods: Totally 1,000 participants (713 males and 287 females; age range: 7 to 80 years) were tested for the absence of PL tendon using Schaffer’s test. In those with a negative Schaffer's test result, Thompson's test, Mishra's test I, Mishra's test II, and Pushpakumar's "two-finger sign" method were used to confirm its absence.

Results:  Absence of PL tendon was found in 95 (9.5%) participants. The PL muscle was absent bilaterally in 42 (4.4%) and unilaterally in 53 (5.5%) participants. Unilateral absence of PL was higher in the right hand (3.0%) (p>0.05). Agenesis of the right side in males was significantly correlated with the left side in males (rs=0.556, p<0.01). Right agenesis in females was significantly correlated with its left side (rs=0.625, p<0.01). The incidence of right and left agenesis in females was more strongly correlated than that in males. Age was significantly correlated with left agenesis (rs=0.154, p<0.01) and right agenesis (rs=0.145, p<0.05) in females.

Conclusion: The prevalence of PL agenesis in the Somali population is lower than the reported incidence of 15%, but more significantly higher than some of the other African populations. These findings may be helpful, particularly for the surgeons in the region, for orthopedic and reconstructive surgeries using PL grafting.

Somali Popülasyonunda Palmaris Longus Tendonunun Varlığı ve Yokluğunun Klinik Tespiti

Abstract

Amaç: Bu çalışmada Somali popülasyonunda palmaris longus (PL) yokluğunun sıklığının Afrika ve dünyanın diğer ülkelerindeki popülasyonlardan farklı olup olmadığı araştırıldı ve bu durumun cinsiyet ve tutulan ekstremite tarafı ile olan ilişkisi incelendi.

Yöntem: Toplam 1000 katılımcı (713 erkek ve 287 kadın; yaş aralığı: 7-80 yıl) Schaffer testi ile PL tendon yokluğu açısından değerlendirildi. Schaffer test sonucu negatif olanlara tanıyı doğrulamak amacıyla Thompson testi, Mishra testi I, Mishra testi II ve Pushpakumar "iki parmak işareti" yöntemi yapıldı.

Bulgular: Katılımcıların 95’inde (%9.5) PL tendonu bulunmuyordu. Katılımcıların 42’sinde (%4.4) iki taraflı ve 53’ünde (%5.5) tek taraflı olarak PL kası yoktu. Tek taraflı PL yokluğu sağ elde daha yüksek oranda izlendi (%3.0) (p>0.05). Erkeklerde sağ taraflı agenezi, erkeklerde sol taraflı agenezi ile anlamlı düzeyde ilişkili bulundu (rs=0.556, p<0.01). Kadınlarda sağ taraflı agenezi, sol taraflı agenezi ile anlamlı düzeyde ilişkili bulundu (rs=0.625, p<0.01). Kadınlarda sağ ve sol taraflı agenezi insidansı, erkeklerinkine kıyasla daha yüksek düzeyde ilişkili idi. Yaş, kadınlarda sol taraflı agenezi (rs=0.154, p<0.01) ve sağ taraflı agenezi (rs=0.145, p<0.05) ile anlamlı düzeyde ilişkili bulundu.

Sonuç: Somali popülasyonunda PL agenezi prevalansı bildirilen %15’lik insidanstan daha düşük olup, diğer Afrika popülasyonlarının bazılarından anlamlı düzeyde daha yüksektir. Bu bulgular, özellikle bölgedeki cerrahlar için PL greftleme ile yapılan ortopedi ve rekonstrüktif ameliyatları açısından yararlı olabilir.
