Multisegmental open sacral fracture due to impalement: a case report.

We report on an unusual impalement injury to the sacrum in a 15-year-old adolescent patient. This open pelvic fracture resulted in a shattered sacrum with neurologic impairment including clinically absent anal sphincter tone and perineal sensation. Early debridement, wound revision, neural decompression, fracture reduction, and stable fixation using lumbopelvic fixation according to the principles of triangular osteosynthesis resulted in a favorable outcome with primary wound healing, return of bowel and bladder control, as well as immediate patient mobilization.

Nonunion of femoral neck fracture and trochanteric osteotomy after a pinned, slipped capital femoral epiphysis: a case report.

Femoral neck fracture as a complication of slipped capital femoral epiphysis (SCFE) is rare. Even rarer is a femoral neck nonunion as an additional complication. This is the first case reported in the literature of a failed valgus osteotomy for a femoral neck nonunion. A salvage operation involving a step-cut valgus/flexion/internal rotation osteotomy, open reduction and internal fixation, with a blade plate and cannulated screw, placement of an allograft femoral strut, and allograft bone grafting was successfully performed. Femoral neck fractures following SCFE fixation are more difficult to treat because of abnormal femoral neck configuration. Therefore a valgus, flexion, and internal rotation producing osteotomy may need to be initially performed to prevent a femoral neck nonunion.

Nonunion treatment: iliac crest bone graft techniques.

In the management of nonunions, detailed surgical treatment plans will vary depending on the underlying etiology of the specific case. Iliac crest autogenous bone grafting, although associated with donor site complications, continues to be a necessary part of the treatment of many nonunions. This article summarizes the classification of nonunions and the use of iliac crest autogenous bone grafting, the standard against which any new technique must be measured.
