BACKGROUND The recent spread of positron emission tomography-computed tomography (PET/CT) poses extremity dosimetry challenges. The question arose whether the radiation dose measured by the ring thermoluminescent dosimeter usually worn on the proximal phalanx (P1) of the index finger measures doses that are representative of the true doses received by the upper extremities of the operators. A p...

OBJECTIVES This article presents force and displacement tolerances for pinch loading of the bones and joints of the digits. METHODS Dynamic (54 mm/s) pinch loading was applied in a dorsal-palmar direction to all digits (fingers and thumb) on matched pairs of hands from 8 adult human cadavers. Opposed 3.1-mm thick, 1.0-mm radius of curvature aluminum pinching surfaces were used to represent th...

A 3-year-old Holstein-Friesian cow was evaluated because of sudden onset of right hind limb lameness and pain with fetlock swelling for 2 days. Based on the history, clinical index scores and computed radiographic examinations, the case was accurately diagnosed to be a severely comminuted fracture of the proximal phalanx. This cow was assigned for conservative treatment with external coaptation...

Chondroblastoma is a rare, benign primary bone tumor that usually occurs at the epiphysis of long bones. The authors present an example of the diagnosis and successful treatment of this neoplasm in an exceedingly rare location in the distal phalanx. Clinical and radiographic outcomes after 68 months of follow-up are presented. A 15-year-old, right hand-dominant, boy developed painful swelling o...
