摘要：The composite bone graft materials were made of calcium sulfate (CaSO4) and sodium hyaluronate (SH). The SH was in the form of solution, with a concentration of 850 kDa 0.1% v/w. The two materials were mixed in a ratio of 2 g:1 mL to obtain the first composite bone graft material Ca_Nw. Next, CaSO4 was mixed with SH-derivative (cross-linked SH) in a ratio of 2 g:1 mL to obtain the second composite bone graft material Ca_Cn. The experiment included 80 patients with ulna and radius nonunion, who were divided into 4 groups. The included patients were treated with Ca_Nw bone graft material, Ca_Cn bone graft material, autograft, and allograft. The computed tomography (CT) data, MIMICS software, and PRO/E software were utilized to construct the finite element models of AO-typing C-type distal radius fractures treated by different bone graft materials. The fixed constraints of radial and ulnar full degree of freedom (DOF) were set. The 120 N axial pressure was given on the forearm to compare the stress and fracture displacement. The results showed excellent stress p simulation effects on two groups of patients treated by composite bone graft materials than those treated by autograft and allograft (P < 0.05).
