Amaç: Bu çalışmanın amacı, elin yapısal özelliklerinin karpal tünel sendromu (KTS) oluşumu ve şiddetinde etkili olup olmadığını araştırmaktır. Gereç ve Yöntemler: Çalışmaya KTS bulunan 212 hasta ve kontrol grubu olarak da 75 sağlıklı gönüllü dâhil edildi. KTS tanısı klinik ve elektrofizyolojik yöntemlerle konuldu. Demografik bilgileri kaydedildi, el bileği genişliği, derinliği, avuç genişliği, el uzunluğu, üçüncü parmak uzunluğu ölçüldü ve el bileği oranı (el bileği derinliği/genişliği), parmak indeksi (üçüncü parmak uzunluğu/el uzunluğu×100), el şekli indeksi (palmar genişlik/el uzunluğu×100) ile el uzunluğu/boy oranları (el uzunluğu/boy×100 değerleri) hesaplandı ve 2 grup arasında karşılaştırıldı. Bulgular: Gruplar arasında cinsiyet, yaş, boy, dominant taraf, öğrenim durumu ve meslek/yapılan iş açısından fark saptanmadı (p>0,05). KTS grubunda vücut ağırlığı ve beden kitle indeksi (BKİ) anlamlı düzeyde daha fazla bulundu (p=0,006 and p<0,001), el bileği oranı ve el uzunluğu/boy oranı ise gruplarda benzerdi (p>0,05). KTS grubunda el şekil indeksi anlamlı düzeyde düşük ve parmak indeksi anlamlı düzeyde yüksek bulundu (p<0,001). Buna göre KTS grubunda elin uzunluğuna kıyasla avuçlar dar, üçüncü parmaklar uzundu. Ayrıca çoklu lojistik regresyon analizine göre yüksek parmak indeksi (B=0,437; p<0,001), düşük el şekil indeksi (B=-0,321p<0,001), düşük el uzunluğu/boy indeksi (B=-0,165; p<0,001) ve yüksek BKİ (B=0,147; p<0,001) KTS oluşumunda bağımsız risk faktörleri olarak bulundu. Hafif, orta ve ileri KTS grupları arasında ise incelenen indeksler açısından fark bulunmadı (p>0,05). Sonuç: Kısa ve dar avuç içine sahip olmak idiyopatik KTS oluşumunda risk faktörü olabilir.

Objectives: This study aimed to examine the impact of hand anthropometric features on the development and severity of carpal tunnel syndrome (CTS). Material and Methods: Demographic characteristics of CTS patients (n=212) and healthy controls (n=75) were recorded. CTS diagnosis was established through clinical and electrophysiological assessments. Wrist width, wrist depth, palmar width, hand length, and 3rd finger length were measured. Additionally, the wrist ratio (wrist depth/width), digit index (3rd finger length/hand length×100), hand shape index (palmar width/hand length×100), and hand length/height ratio (hand length/ height×100) were calculated and compared. Results: No significant differences were observed between the CTS and control groups regarding gender, age, height, dominant hand, educational background, or occupation (p>0.05). However, body weight and body mass index (BMI) were significantly higher in the CTS group (p=0.006 and p<0.001, respectively). The wrist ratio and hand length/height ratio were similar between groups (p>0.05). The CTS group exhibited a significantly lower hand shape index and a significantly higher digit index (p<0.001), indicating relatively narrower palms and longer 3rd fingers compared with the overall hand length. Multivariable logistic regression analysis identified a high digit index (B=0.437; p<0.001), low hand shape index (B=-0.321; p<0.001), low hand length/height ratio (B=-0.165; p<0.001), and high BMI (B=0.147; p<0.001) as independent risk factors for CTS. No significant differences in anthropometric indices were found between the mild, moderate, and severe CTS subgroups (p>0.05). Conclusion: A narrow and short palm may be a risk factor for idiopathic CTS development.
