localized damage to the skin and/or underlying soft tissue usually over a bony prominence
or related to a medical or other device.
A bunion is a bony prominence
that forms at the base of the big toe.
There was mild swelling of the fourth and fifth CMC joint region, and a bony prominence
was felt dorsally.
Pain is more intense in bonier areas like the nape of the neck or near bony prominence
After excision of the bony prominence
, the degeneration tissue, scar tissue, calcified and inflammatory tissue in the field of vision, and the detached portion of the Achilles tendon was reattached to the newly created cancellous surface of the calcaneus using one suture anchor.
When the pressure between the plane of support (such as a mattress or chair) and a bony prominence
(most commonly the sacrum or coccyx, hips, buttocks, elbows or heels) exceeds that of normal arterial capillary pressure, blood flow is reduced, resulting in ischemia and hypoxia.
The usual location is the third metacarpal head, which is the bony prominence
just below the third finger in the palm.
(Note that the big toe is often the site of another common form of arthritis, gout.) The arthritis also may produce a bony prominence
resembling a bunion.
The Henle's Spine (HS)/spina suprameatica/spina suprameatalis/meatal spine or spina meatus, is a small bony prominence
anterior to the supramastoid pit at the posterosuperior margin of the bony external acoustic meatus (Figure 1).
A few of these involve posterior tibial tendinitis, pressure with irritation of the bony prominence
, abnormal biomechanics of the foot, a trauma (eversion sprain) to the synchondrosis between the accessory navicular and the navicular itself, or even a (stress) fracture of the accessory navicular itself.
The National Pressure Ulcer Advisory Panel (NPUAP) defines pressure ulcers (PU) as "localized injury to the skin and/or underlying tissue usually over a bony prominence
, as a result of pressure, or pressure in combination with shear and/or friction" (Agency for Healthcare Research and Quality [AHRQ], 2013, p.
One should avoid midline scar, bony prominence
and skin creases particularly in obese patients.
