Evaluation of the early clinical effect of medical calcium sulfate in traumatic fracture treatment / 实用医学杂志

ABSTRACT

Objective To investigate the X-ray gray scale changes of calcium sulfate and evaluate its clini-cal effect in traumatic fracture treatment. Methods 23 traumatic fracture cases were treated from September 2014 to January 2016 in our hospital. The degradation rate of calcium sulfate was evaluated by X ray assay. Results Af-ter surgery,about 69%remnants at 1 week,53%remnants at 2 weeks,26%remnants at 4 weeks,7%remnants at 6 weeks were observed,while no remnants were found at 8 weeks after surgery. The initial time window of callus appearance was 3 to 9 weeks and the mean time was(6.5 ± 1.6)weeks. The fracture union time was 8 to 24 weeks and the mean time was(15.0 ± 5.2)weeks. One patient with distal humeral comminuted fracture had non-infec-tious delayed healing wound.One case of hemolytic staphylococcus in incision was cultured. Conclusion Calcium sulfate degrades rapidly,cautions should be taken for the application in the superficial bone.
