Distal tibial fracture below a total knee arthroplasty: retrograde intramedullary nailing as an alternative method of treatment: a case report.

An 85-year-old woman with a history of insulin-dependent diabetes mellitus, hypertension, and chronic venous insufficiency with underlying venous stasis who sustained a fall in her house presented to the emergency room with a displaced distal diaphyseal tibial fracture and a stable total knee arthroplasty. At her third day of admission, an intramedullary nail was inserted in a retrograde fashion through the calcaneus and talus into her tibial shaft to stabilize the fracture; there were no postoperative complications. Three years after surgery, the patient remains pain-free, the fracture had united, and her functional status is the same as it was before the fracture. There are different options for solving these types of fractures. Nonoperative, external fixation, conventional or locking plates and antegrade and retrograde intramedullary nailing could be used; however, they should be weighed against the particular issues of the patient involved. We think that a retrograde nailing technique through the calcaneotalotibial axis could be an alternative method for these types of fractures in a fragile patient with important comorbidities with few complications and good functional outcome.
