Objective To observe the results of bone bolt crews in treatment of the haplo-detached distal tibiofibular joint.Methods The haplo-detached distal tibiofibular joint were fixed with bone bolt in 7 patients.Their outcomes were evaevaluated according to Mast and Teipner criteria and X-ray.Results All 7 patients were followed up from 12 to 36 months.All were assessed as good,and no fair or poor cases were found.Conclusion Bone bolt fixation was believed to be a good method to treat the haplo-detached distal tibiofibular joint with simple operation,beared shear force and control of brew tightress and was helpful in weight loading and functional exercises in the earlier period after operation,so bone bolt fixation was good in practical value in clinc.
