plateau fractures. Bucholz-RW; Carlton-A; Holmes-R Division of Orthopaedic Surgery, University of Texas Southwestern Medical Center, Dallas 75235. Clin-Orthop. 1989 Mar(240): 53-62 The metaphyseal defects in 40 patients with displaced tibial plateau fractures necessitating surgical repair were filled with either cancellous autograft or interporous hydroxyapatite. Roentgenographic and clinical assessments at follow-up periods averaging 15.4 months (autograft) and 34.5 months (hydroxyapatite) demonstrated no significant differences in the two groups. Interporous hydroxyapatite is a safe, effective alternative to autogenous cancellous bone for the filling of metaphyseal defects associated with tibial plateau fractures.
