A two-year-old Braunvieh heifer was presented with a traumatic luxation of the second
phalanx of the medial digit and concurrent subluxation of the second phalanx of the
lateral digit of the right hindlimb. Closed reduction of both luxations was possible.
Surgical arthrodesis was achieved using one narrow 4.5 mm three-hole equine locking
compression plate for each joint. Placement of the bone plates resulted in stable
arthrodesis of both proximal interphalangeal joints of the right hindlimb but there
was persistent residual lameness. The heifer delivered a healthy calf but was slaughtered
eight months after surgery because of varus deformity of the contralateral limb. Radio-graphs
taken post-mortem revealed pronounced periosteal reactions involving both proximal
interphalangeal joints and only partial bony bridging of the joint spaces.
