Treatment of high-energy proximal tibial fractures using the Monticelli-Spinelli external fixator: a preliminary...

Between 1990 to 1993, 21 patients with tibial plateau or proximal tibial fractures resulting from high-energy trauma were treated with the Monticelli-Spinelli external fixator. There were 13 men and 8 women (mean age, 45.2 years; range, 26 to 78). There were a total of 5 type A, 2 type B, and 14 type C fractures, using the Arbeitsgemeinschaft Fur Osteosynthesefragen (AO) classification system. Immediate postoperative reductions were good or excellent, according to strict radiographic criteria, in 16 of 21 patients. All patients obtained at least 90 degrees of knee flexion, and only one patient lost more than 5 degrees of full extension. Complications included seven superficial pin-tract infections and one deep vein thrombosis with resultant pulmonary embolism. Nineteen patients were available for follow-up (mean, 14 months). Clinically, 13 patients had satisfactory results where good or excellent radiographic reductions were maintained, knee extension was within 5 degrees of full, flexion was > or = 90 degrees, with < or = 5 degrees valgus/varus angulation. Six patients had unsatisfactory results, not meeting the above criteria. The Monticelli-Spinelli external fixator is a much-needed tool in the treatment of high-energy tibial plateau fractures that are not amenable to more extensive surgical procedures because of the associated soft-tissue injuries.
