Clinical study of percutaneous K-wire fixation and transplantation of autogenous bone marrow for treatment of Herbert typeIscaphoid fracture

Objective To observe the clinical results of percutaneous K-wire fixation and autogenous bone marrow transplantation for Herbert type I soaphoid fractures.Methods Thirty-six cases of fresh Herbert type I scaphoid fractures were treated by percutaneous K-wire fixation.Meanwhile 5ml autogenous bone marrow was injected to the fracture site.CR-X ray films were collected weekly from 6th week after the operation till healing of the fracture.The time for bone union and return to work was recorded.Results All cases were followed-up for 6 weeks to 4 years. Bone union was achieved in all cases.The duration of bone union ranged from 7 to 12 weeks,the average being 8.3 weeks.Range of motion was the same as that of the healthy side in 35 cases after rehabilitation.Those patients were pain free and returned to original work.Wrist movement of 1 case was impaired to some extent.There was also motion pain.Conclusion Pereutaneeus K-wire fixation and autogenous bone marrow transplantation is a minimally invasive, simple,and safe method to treat Herbert type I scaphoid fractures.It avoids iatrogenic injuries,reduces healing time, and increases healing rate.
