Repair of bony defective nonunion of humeral condyle using autologous platelet-rich-plasma combined with iliac autograft / 中华创伤骨科杂志

ABSTRACT

Objective To investigate the clinical effectiveness of autologous platelet-rich-plasma (PRP) combined with iliac autograft in reconstruction of bony defective nonunion of humeral condyle.Methods The 27 patients who had been admitted to our department from January 2004 to June 2015 for bony defective nonunion of humeral condyle were analyzed retrospectively.Of them,15 underwent reconstruction with PRP combined with iliac autograft (experimental group) and 12 reconstruction with only iliac autograft (control group).The preoperative demographic data of the 2 groups were not significantly different (P ＞ 0.05).The 2 groups were compared in terms of operation time,hospital stay,bony union time,range of motion of the elbow,and modified Cassebaum scoring.Results The patients were followed up for 12 to 90 months (average,24.6 months).No such complications were observed as displacement of bone blocks,loosening or breakage of implants,re-nonunion,malunion,delayed ulnar neuritis,or olecranon nonunion.There were no statistic differences between the 2 groups regarding operation time,hospital stay,range of motion of the elbow and modified Cassebaum scoring (P ＞ 0.05).The clinical healing time (4.2 ± 1.3 months) and bony healing time (4.8 ± 1.4 months) for the experimental group were significantly shorter than for the control group (6.0 ± 1.1 months and 6.2 ± 1.0 months,respectively) (P ＜ 0.05).Conclusion Autologous PRP combined with iliac autograft can speed up the healing of bony defective nonunion of humeral condyle,promoting functional recovery of the elbow.
