Fragment interpositioning

When more than one molecule is present in the structure, the various fragments may overlap after a cleanup. This overlap is not usually severe because of the molecular recentering step in postassembly. More serious overlap occurs when one is drawing de novo because the emerging fragments are generally superimposed initially, and it becomes important to space them apart. The problem is deceptively difficult to solve well, and space does not permit an extensive discussion here. See also the section near the end of the chapter on Reaction Layout.

Hubner et al. 2000 Kayser et al. 2003). In specific settings, US is an efficient means to detect interposition of soft tissues within the fracture line that can interfere with healing, as well as to identify nerve impingement between fracture fragments or inside a callus (see Chapters 4, 7) (Sooner et al. 1999,2001 Tukenmez et al. 2006).
