Radiographic Evaluation of the Anconeal Process in Skeletally Immature Dogs

Abstract

Because radiographic diagnosis of a SCO of the anconeal process and UAP lesions have distinct appearances, an earlier diagnosis of UAP is possible.

Analysis of risk factors for elbow dysplasia in giant breed dogs

“…When a SCOAP is present, a lucent line is identified separating the anconeal process from the olecranon on radiographs in dogs between 10-13 weeks of age, with the expected time of fusion to the olecranon reported to occur at less than 20 weeks of age (14). A UAP is diagnosed when there is persistence of the lucency between the anconeal process and olecranon in dogs over 22-24 weeks of age due to a failure of SCOAP closure (4,15). However, recent evidence suggests that most breeds of dog do not have a SCOAP (15).…”

However, recent evidence suggests that most breeds of dog do not have a SCOAP (15). Furthermore, SCOAP has not been described in many of the breeds with the highest prevalence of UAP, including the Bernese Mountain dog, Rottweiler, Mastiff, St. Bernard and Newfoundland (1,15,16).…”

“…However, recent evidence suggests that most breeds of dog do not have a SCOAP (15). Furthermore, SCOAP has not been described in many of the breeds with the highest prevalence of UAP, including the Bernese Mountain dog, Rottweiler, Mastiff, St. Bernard and Newfoundland (1,15,16). Alternatively, UAP has been proposed to occur secondary to dyssynchronous growth between the radius and ulna, with secondary incongruency leading to altered biomechanical forces to the olecranon and anconeal process resulting in UAP (8).…”

Avaliação radiográfica e tomográfica da articulação umerorradioulnar em cães

“…Na maioria dos casos de DC, os primeiros sinais de claudicação ocorrem de 6 a 12 meses de idade, mas alguns cães apresentam sinais mais tardios (WIND, 1986;FOURIE, 1998;BRUGGEN et al, 2010;TEMWICHITR et al, 2010;LAVRIJSEN et al, 2012;MICHELSEN, 2012 FOURIE, 1998;POLLARD, 2007;FRAZHO et al, 2010;GASCH et al, 2012). Breit et al (2004) semana e a ossificação do processo coronóide medial completa-se após 6 semanas.…”

“…A etiologia exata da NUPA não é completamente elucidada, mas fatores traumáticos, metabólicos e genéticos tem sido apontados como causas de NUPA (SJOSTROM et al, 1995;GASCH et al, 2012). O diagnóstico definitivo de NUPA deve ser feito se o processo ancôneo não estiver unido após 24 semanas de idade (FRAZHO et al, 2010). Ljunggren et al (1966) e Fox et al (1983 relataram que a raça mais acometida é Pastor alemão.…”
