Jimmy's journey with Radius Curvus Syndrome 

Jimmy is a 14-month-old Poodle who developed a right forelimb lameness and exercise intolerance after a traumatic incident when he was puppy. On examination he showed pain on manipulation of the elbow. Radiographs confirmed gross angular limb deformity with carpal valgus radial procurvatum and elbow incongruity, findings which may be found with radius curvus syndrome.

This is most commonly associated with premature closure of the distal ulna physis resulting in a typical bowing and external rotation of the forelimb. Surgical correction was advised based on existing arthrosis and exercise intolerance. Pre operative planning using orthogonal radiography has typically allowed for localization of the deformity evident as the CORA.

More recently 3D evaluation based on CT scans has added value to more accurate planning. This was be taken one step further using 3D computer aided design modelling combined with 3D printing and the creation of an exact model with surgical cutting and reduction guides to aid in surgical planning an accuracy.

The models were used to simulate the surgical procedure allowing for implant planning, and contouring prior to taking him into the OR.  The precise plastic replicas of Jimmy’s forelimb bones can be sterilized and used for intraoperative references saving time and hopefully improving surgical outcomes.
