Abstract

Ectrodactyly is a rare anomaly seen in the appendicular skeleton and characterized by a cleft or split between bone and soft tissue in the distal regions of the extremities. Ectrodactyly may be associated with the absence and hypoplasia of several carpal-metacarpal bones, phalanx duplication, or metacarpal synostosis. In this case report, a 2-years-old mixed breed male dog was presented withhold up the left forelimb and inspectional abnormality with a cleft. In the radiographic images, it was observed that the fourth phalanx and the fourth distal carpal bone were absent in the related extremity, the cleft extended up to the carpal joint and there was an incongruity between the radius and ulna. The cleft between the metacarpal bones was stabilized using 2 lag screws and corticocancellous bone graft. The incongruity between the carpal joints was eliminated by pancarpal arthrodesis and ulna ostectomy was performed for the incongruity between radius and ulna. It has been observed that postoperative physical therapy exercises with correlated methods have positive long-term results in the related extremity.

2 yaşlı melez ırk bir köpekte ektrodaktili olgusu

Abstract

Ektrodaktili, apendiküler iskelette görülen nadir bir anomali olup, ektremitelerin distal bölgelerinde kemik ve yumuşak doku arasında şekillenen yarık ya da bölünme ile karakterizedir. Ektrodaktili birkaç karpal-metacarpal kemiğin yokluğu/hipoplazisi, phalanks duplikasyonu ya da metacarpal sinostos ile ilişkili olabilir. Bu olgu sunumunda 2 yaşında, melez ırk, erkek bir köpek, sol ön ekstremitesini yukarıda tutma ve dış bakıda gözlenebilen bir yarık şikayeti ile getirildi. Alınan radyografik görüntülerde ilgili ekstremitede dördüncü phalanx’ın ve dördüncü distal carpal kemiğin olmadığı, yarığın carpal ekleme kadar uzandığı ve radius ile ulna arasında uyumsuzluk olduğu görüldü. Metacarpal kemikler arasındaki yarık 2 adet lag vidası ve kortikokansellöz kemik grefti kullanılarak stabilize edildi. Carpal eklemler arasındaki uyumsuzluk pancarpal artrodez yöntemi ile giderildi ve radius ile ulna arasındaki uyumsuzluk için ulna ostektomisi uygulandı. Uygulanan korrektif yöntemler ile operasyon sonrası uygulanan fizik tedavi egzersizlerinin, ilgili ekstremitedeki uzun dönem sonuçlarının olumlu olduğu gözlenmiştir.
