Ekstansör karpi ulnaristen ayrılan aksesuar tendon slibi ve bilek ağrısındaki önemi

Amaç: Ekstansör karpi ulnarisin (ECU) anatomik varyasyonları bilekte ve küçük parmakta fonksiyon yetersizliğine neden olabilir. Bu çalışmanın amacı ECUdan ayrılan aksesuar tendonun sayısı, kalınlığı ve tipini belirlemekti. Çalışma planı: Kadavralardan elde edilen elli dört ön kol ve elde ECUdan ayrılan aksesuar tendon varlığı, görünümü, boyu, şekli, kalınlığı, yeri ve seyri açısından incelendi. Bulgular: ECUdan ayrılan aksesuar tendon slibi 2 sol, 1 sağ, toplam 3 elde (%5.6) görüldü. Bu slipler ECUnun tendonundan ayrıldıktan sonra ekstansör digiti minimi tendonunun ulnar tarafında ilerleyip 5. parmağın ekstansör yüzünde sonlanıyordu. Sliplerin ortalama eni 1.4±0.01 mm idi. Çıkarımlar: El sırtıyla ilgili klinik tanı ve cerrahi işlemlerde ECUnun bu anatomik varyasyonu dikkate alınmalıdır. Eklem tenosinoviti ve subluksasyonu tedavisinde bu slibin olabileceği de unutulmamalıdır.

Accessory tendon slip arising from the extensor carpi ulnaris and its importance for wrist pain

Objective: The anatomical variations of the extensor carpi ulnaris (ECU) muscle can cause a functional impairment of the wrist and the little finger. The aim of this study was to determine the number, thickness and type of accessory tendon arising from the ECU. Methods: The presence of an accessory tendinous slip from the ECU muscle was examined in terms of gross appearance, size, shape, thickness, location and distribution in 54 cadaveric forearms. Results: The accessory slips arising from the ECU muscle were observed in three specimens (5.6%) (two left, one right). These slips ran to the ulnar side of the extensor digiti minimi tendon, originated from the head of the ECU, and ended on the extensor apparatus of the fifth finger. The mean width of the tendinous slips was 1.4±0.01 mm. Conclusion: This anatomic variation of the ECU should be considered in diagnostic and surgical procedures involving the dorsum of the hand. Its clinical importance in the treatment of tenosynovitis and subluxation of joints is also stressed.
