OBJECTIVES To describe a novel canine castless partial carpal arthrodesis plate (par-CA) and its ex vivo biomechanical comparison with T-plate and cross pinning techniques for canine partial carpal arthrodesis. METHODS The three implant systems were applied to three cohorts of six forelimbs from Greyhounds euthanatized for reasons unrelated to the study. Intercarpal and carpometacarpal palmar...

This study presents design and implementation of an efficient skeletal bone age assessment (BAA) procedure based on features extracted from two dominant wrist bone structures (radius & carpal bones). System works according to renowned Tanner & Whitehouse (TW2) method, based on carpal and epiphyseal region of interest (ROI). It ensures accurate and robust BAA for both girls and boys (age range, ...

We report on a 74-year-old man with extensor indicis proprius (EIP) tendon rupture secondary to avascular necrosis and collapse of the scaphoid. The collapsed scaphoid was removed, followed by 4-corner fusion and tendon transfer of the extensor digiti minimi to the EIP. At the 3-year follow-up, the patient was painfree and had full extension of his left index finger, with proper alignment of th...

The following case report describes the diagnosis and surgery of bilateral polydactyly of unknown origin in a colt. A 7-month-old Berber colt was referred for cosmetic and curative excision of supernumerary digits. Radiographic examination revealed bilateral polydactyly and welldeveloped first carpal bones. Surgery consisted of an osteotomy of both second metacarpal bones combined with an amput...

The wrist is one of the most intricate articulations of the musculoskeletal system, in which the delicate balance is maintained by a complex set of intrinsic and extrinsic ligamentous connections between seven carpal bones. Injuries to the bones and ligaments in the wrist may potentially irreversibly disrupt this balance and initiate progressive degenerative disease and osteoarthritis (OA). Mus...

Fig. 1. X-ray of left forearm and hand showing osteosclerosis, ‘bone in bone’ appearance of shaft, fracture both bones, fraying and early cupping of metaphysis and widening of ‘physis’, the growth plate and absence of carpal bones. pathological fractures with ‘bone in bone’ appearance, increase in medullary density, defective metaphyseal remodeling with fraying and early cupping and widening of...

Introduction/Methods: Scaphoid fractures are the most common fractures of the carpal bones of the wrist, and represent 11% of all fractures of the upper extremity and between 70% and 80% of all carpal fractures. In most cases, the mechanism of injury is a fall with the wrist extended. Although conservative treatment of stable fractures of the carpal scaphoid associated with a high rate of conso...
