Clinical study of minimally invasive percutaneous crossover K-wire fixation of scaphoid fractures under C-arm / 国际外科学杂志

ABSTRACT

Objective To observe the clinical efficacy of minimally invasive percutaneous K-wire crossover fixation treating scaphoid fractures under C-arm.Methods From March 2011 to May 2014,20 patients with fresh scaphoid fractures had postoperative regular outpatient follow-up.Evaluation indicators included Cooney wrist scoring system,X-ray assessment of fracture healing,questionnaire survey of patient's subjective satisfaction at the final follow-up.Results All patients were followed up for 4 to 18 months,the mean follow-up time being 10 months.Postoperative X-ray showed all cases achieved bony union within 8 to 12 weeks,an average of 9.2 weeks.The questionaire resuits of patient's subjective satisfaction showed that general feeling of treatment in 2 cases,relatively satisfied in 2 cases,greatly satisfied in remaining 16 patients at the final follow-up.According to the postoperative Cooney wrist score,excellent in 8 cases,good in 10 cases,fair in 2 cases,the overall satisfactory rate was 90.2％.There were not pin tract infection,nonunion,malunion,avascular necrosis of scaphoid and other complications.2 cases showed that wrist pain during weight-bearing activities and weather getting cold,minor limitations of wrist function and degree of activity,grip strength slightly worse than the contralateral.Conclusions Minimally invasive percutaneous K-wire crossover fixation under C-arm combined with postoperative plaster external fixation properly can attain good clinical results in the treating of scaphoid fractures and worthy of further promotion.
