partial-thickness thermal necrosis of the skin caused by prolonged therapy entailing applications of ice.
ice ball; ice burn blanched area of frozen tissue induced by cryotherapy; ice ball area must exceed that of the lesion as the peripheral temperature of the ice ball approaches normal tissue temperature; only the tissue at the centre of the ice ball is reliably destroyed by freezing process (see Table 1; cryosurgery)
|Indications||Single isolated skin lesions, after debridement of overlying callosity|
|Contraindications||Patients with peripheral articular disease, Raynaud's or any other cause of reduced tissue perfusion or reduced healing|
Patients with a low pain threshold
Lesions that overlie joints, or in areas where there is little or reduced fibrofatty padding
