Application of Screws to Treatment of Scaphoid Fracture by Palm-side Retrograde Internal Fixation in Young Soldiers

Objective To evaluate the therapeutic results of scaphoid fracture of young soldiers with palm-side retrograde internal fixation using screws.Methods Fourteen cases of soldiers'scaphoid fracture were treated with screws by palm-side retrograde internal fixation.Cooney's clinical evaluation system was used to evaluate the results according to wrist pain,moving extension and gripping strength.Results In the 14 cases,13 achieved bone union and one nonunion.The mean time of union was 12 weeks.The wrist mean motion range was about 90% of the healthy lateral wrist and mean gripping strength was about 95%.Twelve patients suffered from no pain,one patient from slight pain,and one patient with nonunion from medial pain.According to Cooney's clinical evaluation system, the outcome was fine in 10,good in three and bad in one patient(s).Conclusion Palm-side retrograde internal fixation with screws for soldiers' scaphoid fracture has some advantage such as simple operation,little destruction to remanent blood supply,stable fixation,reduced bone healing time and increased healing rate,so it is an effective way to the treatment of scaphoid fracture.
