Hybrid external fixation of comminuted tibial plateau fractures.

Comminuted tibial plateau fractures present a surgical challenge to the orthopaedic surgeon. Over the years, treatment has ranged from traction to cast immobilization to open reduction and internal fixation. More recently, indirect reduction techniques with external fixation have been used. At the authors' institution, from 1990 to 1992, 18 Schatzker Types V and VI tibial plateau fractures were treated in 18 patients with indirect reduction and application of a Monticelli-Spinelli hybrid external fixation system. Two patients had additional internal fixation and were excluded from this review. All 16 patients were available for followup evaluation. The mean time to union was 4.5 months. There were no nonunions. Three patients developed a varus deformity. Fifteen had radiographic evidence of early degenerative changes at 1 year followup. There were 11 superficial pin tract infections in 4 patients; all resolved with local pin care and a short course of oral antibiotics. There were no deep infections. With the added advantages of minimal to no soft tissue stripping and early knee range of motion, this technique is recommended for treatment of these difficult fractures.
