Effect of Nerve-Cutting Technique on Nerve Microstructure and Neuroma Formation.

Peripheral neuroma formation results from partial or complete nerve division. Elucidating measures to prevent the development of peripheral neuromas is of clinical importance. The aim of this study was to determine the effect of various surgical nerve-cutting techniques on nerve microstructure and resultant neuroma formation.

Accuracy in Screw Selection in a Cadaveric, Small-Bone Fracture Model.

Purpose: Using a cadaveric model simulating clinical situations experienced during open reduction and internal fixation of proximal phalangeal fractures, the aim of this study was to evaluate the relationship between level of training and the rates of short, long, and ideal screw length selection based on depth gauge use without fluoroscopy assistance.

Methods: A dorsal approach to the proximal phalanx was performed on the index, middle, and ring fingers of 4 cadaveric specimens, and 3 drill holes were placed in each phalanx. Volunteers at different levels of training then measured the drill holes with a depth gauge and selected appropriate screw sizes.

Volar Anatomy of the Proximal Phalanx: Implications for Screw Length Selection for Fixation of Shaft Fractures.

Purpose: To investigate the anatomy of the volar surface of the proximal phalanx of the hand, specifically the longitudinal groove running along the volar phalangeal shaft.

Methods: We measured skeletonized proximal phalanges from 10 embalmed human cadaver hands at 5 equidistant points along the shaft. The difference between the maximum dorsal-palmar thickness of the shaft and thickness measured from the center of the volar groove to the most dorsal aspect of the phalanx indicated the depth of the groove at each point.

Cartilage Degeneration, Subchondral Mineral and Meniscal Mineral Densities in Hartley and Strain 13 Guinea Pigs.

Osteoarthritis is a joint disease involved in articular cartilage, subchondral bone, meniscus and synovial membrane. This study sought to examine cartilage degeneration, subchondral bone mineral density (BMD) and meniscal mineral density (MD) in male Hartley, female Hartley and female strain 13 guinea pigs to determine the association of cartilage degeneration with subchondral BMD and meniscal MD. Cartilage degeneration, subchondral BMD and meniscal MD in 12 months old guinea pigs were examined with histochemistry, X-ray densitometry and calcium analysis.

Getting comfortable with death. Palliative care begins at home.

Palliative care is multidimensional care of patients with life-limiting diseases concurrent with active disease management, together with support for their caregivers. Components of primary palliative care include management of physical and psychological symptoms and discussions about goals of care and end of life wishes. Primary care physicians and all specialty physicians should provide primary palliative care for their chronically ill patients.
