Dressings Use of dressings in the management of pin sites is another aspect of care where there is little or no research and considerable variation in practice (Holmes et al2005). Behrens (1989) recommended that pin site dressings should not be left undisturbed for too long in early post-operative stages, as this may prevent observation of the area surrounding the pins to ensure there is no vascular disturbance. Behrens (1989) also acknowledged that a balance must be struck between inadequate and too frequent pin care to prevent complications.
