ABSTRACT
Objective To investigate an effective method for treatment of scaphoid nonunion.Methods Based on the applied anatomy study of 12 fresh upper limb specimens of human adult cadavers,a new transfer of vascular pedicled radius with the 1st,2nd intercompartmeiilal supraretinacular arteries has been designed to treat nonunion of scaphoid fractures in 23 cases since 1997.Results All cases were followed up from 6 months to 3 years and their fractured seaphoids got united 3 to 7 months after the operation.The bony union rate was 100%.Rate of excellent and good restoration of normal wrist function was 95.7%.Conclusion This method for treatment of nonunion of scaphoid fractures is re commendable,for it is simple to manage,less invasive,and effective.
ABSTRACT
Objective To explore the possible causes and treatment of nonunion of fractures of diaphysis of radius and ulna. Methods According to different personal conditions and results of X gram, 73 cases of the nonunion fractures of diaphysis of radius and ulna were treated with different internal fixations, autologus spongy bone transplantation, release of scar and interosseous membrane, or local skin flap transposition. All had early functional mobilization of the forearm after operation. Results The patients were followed up for 12 to 29 months. All the cases had bony union, and 64 cases(87.7% ) obtained satisfactory functional rehabilitation. Conclusion The major causes that may lead to the nonunion of the diaphysis of radius and ulna are conditions of local soft tissue, site and severity of the fracture, security of internal fixation, and improper early movement, rather than infection. Proper internal fixation, autologus spongy bone transplantation, and release of scar and interosseous membrane are effective in treatment of the nonunion of the fracture and in the functional rehabilitation of the forearms.
