Bad Split: Anatomic or Technical Problem? June 2015 Journal of oral and maxillofacial surgery: official journal of the American Association of Oral and Maxillofacial Surgeons 73(6)

Despite a large number of variations of the original Obwegeser–Dal Pont splitting technique, the risk of unexpected fractures is a major disadvantage of the BSSO, 31 known as “bad splits.” Previous reports have cited an incidence of bad splits of up to 5% despite improved preoperative diagnostics.

Patient factors predictive of a bad split reported in the literature are controversial. One of the common operative complications during bilateral sagittal split osteotomy (BSSO) is a bad split, an undesired fracture of the mandible at the proximal or distal fragment. The incidence of bad splits varies between 0.9 and 20%. A bad split can lead to infection, bony sequestration of the fragments, delayed bone healing, and pseudoarthrosis.

Bad splits may cause mechanical instability, a disturbance in bony union, and lead to bone sequestration with subsequent infection. An unfavourable fracture, known as a bad split, is a common operative complication in bilateral sagittal split osteotomy (BSSO). The reported incidence ranges from 0.5 to 5.5%/site.
