Fractures and ligamentous injuries of the front paw are common in small animals and usually result from direct trauma, such as vehicular accident, collision with a stationary object, falls from a height, or entrapment of the paw with leverage (eg, stepping in a hole while running).

Metacarpal and phalangeal fractures may be associated with concurrent ligamentous injury. Tendon and paw injuries are generally associated with direct traumatic etiologies, such as laceration.

AIMS: To report the clinical outcomes and complications after the use of 3.5 mm/2.7 mm locking compression plates (LCP) with additional internal fixation for pancarpal arthrodesis (PCA) in dogs.

Authors: Castelli E, Pozzi A, Klisch K, Scotti L, Hoey S, Dennler M.

OBJECTIVE: To compare the quality of visualization of canine carpal ligaments by using computed tomography (CT), MRI, CT arthrography (CTA), and magnetic resonance arthrography (MRA).

STUDY DESIGN: Prospective descriptive study.

OBJECTIVE: To describe normal antebrachiocarpal joint kinematic motion during axial loading and to describe the effect of palmar radiocarpal ligament (PRL) and palmar ulnocarpal ligament (PUL) transection on this motion.

SAMPLE POPULATION: Ten forelimbs from 5 adult greyhound cadavers.

OBJECTIVES: 1) To describe a radiographic method for determination of joint orientation lines and anatomical joint angles in orthogonal planes of feline radii; 2) to establish a range of normal radial joint orientation angles and anatomical axes in a feline population; and 3) to assess the repeatability and reliability of this methodology.

This report describes the successful management of a carpal hyperextension injury in a cat using combined temporary transarticular internal and external skeletal fixation, without performing an arthrodesis. To our knowledge, there have been no previous reports of management of feline carpal hyperextension injuries in this fashion.

To report thoracic limb alignment values in healthy dogs; to determine if limb alignment values are significantly different when obtained from standing versus recumbent radiographic projections.

Objective-To determine whether carpal brace application is a viable treatment for dogs with unilateral carpal ligament instability. Design-Retrospective case series. Animals-14 client-owned athletic dogs. Procedures-Medical records were reviewed to identify dogs treated with abrace for unilateral carpal valgus or varus instability between August 2008 and August 2011. Treatment included passive motion and isometric strengthening exercises during brace application. Results-Of the 14 dogs, 11 were considered to have returned to normal function; 11 of 12 dogs returned to agility competition.

This report describes the treatment of traumatic carpal hyperextension in a giant breed dog by pancarpal arthrodesis using a custom-made Fixin locking plate, created with the aid of a three-dimensional plastic model of the bones of the antebrachium produced by rapid prototyping technology. A three-year-old 104 kg male Mastiff dog was admitted for treatment of carpal hyperextension injury. After diagnosis of carpal instability, surgery was recommended. Computed tomography images were used to create a life-size three-dimensional plastic model of the forelimb.
