ABSTRACT
@#Objective To investigate the outcome of trans-scaphoid perilunar dislocation treated with bone anchor and AO/ASIF hollow screw.Methods Eight patients with trans-scaphoid perilunar dislocation were treated by Depuy Mitek bone anchor and AO/ASIF hollow screw.The postoperative follow-up period was 6～24 months(average 11.1±5.3 months).All patients were assessed by the Cooney's grading system.Results The outcomes of 8 patients were execellent in 5 cases,good in 2 cases,general in 1 case.6 cases got pain relief with an increase of range of motor and grip strength at certain drgree.Postoperative roentgenogram displayed congruity among wrist bones,with no fracture disunion,no loose internal fixation and no traumatic arthritis.Conclusion The bone anchor and hollow screw have advantages as simple-manipulated and reliable for treating trans-scaphoid perilunar dislocation.
