This in vivo goat study compares calcium phosphate cement (α-BSM) versus cancellous autograft for maintaining reduction in depressed lateral tibial plateau fractures, using a standardized 8 mm subchondral defect model without internal fixation, followed from 24 hours to 18 months.
When managing depressed tibial plateau fractures with subchondral void filling, autograft alone compresses under early weight-bearing and cannot maintain reduction — calcium phosphate cement provides immediate structural support that autograft cannot, potentially reducing subsidence risk and the hardware burden needed to hold the fragment while the defect heals.
