Successful Management of Congenital Radial Head Subluxation in a Juvenile Dog Using Ultra-High Molecular Weight Polyethylene Suture Toggle

Congenital humeroradial subluxation was diagnosed by clinical examination and radiography in a 16-week-old female dog that presented for left forelimb lameness. This was treated surgically by open reduction followed by placement of an ultra-high molecular weight polyethylene suture from the craniolateral aspect of the proximal radius to the caudomedial aspect of the ulna, secured with a toggle and suture button. Postoperative findings were consistent with clinical improvement and radiographs were compatible with resolution of elbow subluxation. To our knowledge, this is the first case report of congenital humeroradial subluxation to be managed with an ultra-high molecular weight polyethylene suture toggle.
