The palmar region of the canine carpus may be injured by traumatic, inflammatory, infectious, neoplastic, and degenerative disorders. The normal ultrasonographic anatomic features of the dorsal region of the canine carpus have been published, however information regarding the palmar region is currently lacking.

The aims of this prospective, descriptive, anatomic study were (1) to describe the normal ultrasonographic characteristics of the palmar carpal structures in medium to large-breed dogs, and (2) to establish a standardized ultrasonographic protocol for evaluating them.

Objective: The aim of this study was to evaluate outcomes and complications of dogs that had pancarpal arthrodesis (PCA) using a titanium hybrid advanced locking plate system (ALPS) and stainless steel hybrid dynamic compression plate (HDCP).

Study design: Retrospective observational study.

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.

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.
