Summary
Caudal elbow arthrotomy by use of triceps tenotomy was performed for open reduction
of “Y-T” fractures of the humeral condyle in three dogs. Stabilization of the fracture
was achieved by use of a bone screw inserted with a lag effect to compress the articular
fracture and placement of bone plates on the caudolateral surface of the lateral epicondylar
crest and the caudomedial surface of the medial epicondylar crest. This construct
successfully maintained reduction in all three dogs without implant loosening or breakage.
All three of the fractures healed satisfactorily without any evidence of progressive
osteoarthritis. Long-term (median - 20 months) function of the affected limb was comparable
to the contralateral limb, with little loss of elbow range-of-motion and minimal to
an absence of lameness.
Triceps tenotomy was used for open reduction of “Y-T” fractures of the humeral condyle
in three dogs. Stabilization of the fracture with a bone screw inserted for lag effect
and use of a bone plate on each epicondylar crest resulted in satisfactory healing
of the fracture and good limb function in all of the patients.
