Experimental study and clinical observation of minimum-contact plate in long bone fracture / 中华创伤杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To study the mechanical properties and the clinical results of minimum-contact plate in the treatment of fractures.</p><p><b>METHODS</b>Four-point bending and torsion tests were conducted to compare the new minimum contact plate (MCP) with dynamic compression plate (DCP) and limited contact dynamic compression plate (LC-DCP). The fracture healing time and growth of bony callus were observed in 29 cases of long bone fracture fixed with MCP to evaluate the advantages of this kind of plate.</p><p><b>RESULTS</b>The 29 patients who underwent MCP were followed up from 6 to 14 months. The average healing time for femoral, tibial and humeral fractures was 12, 13 and 10 weeks, respectively. All fractures were healed. No displacement of fracture, screw pullout, deformation or break of the plate were found.</p><p><b>CONCLUSIONS</b>The bending stiffness of MCP is significantly greater than that of DCP and LC-DCP (P<0.05). MCP can protect the periosteal blood supply against avascular osseous necrosis and accelerate bone healing. It is a kind of reliable and effective plate in treatment of fractures.</p>
