Abstract: Objective　To explore the clinical effect and experience of three kinds of functional free muscle transplantation in the reconstruction of partial upper limb function.　Methods　From January 2010 to December 2018, functional free gracilis , latissimus dorsi  and pectoralis minor muscle transplantation were applied to reconstruct upper limb function in 39 cases, including reconstructing elbow flexion and finger flexion function in 6 cases, finger flexion function in 11 cases, and thumb opposable function in 22 cases. Different dynamic nerves and blood supply vessels were selected according to the conditions of the limbs, and the transplanted muscles were adjusted in the optimal position of muscle tension during the operation to rebuild the nerve and blood supply of the transplanted muscles.　Results　In 37 cases, the functional free muscle survived completely, and the reconstructed upper limb recovered well.  Excellent and good rates were 94.8%. In 2 cases, the reconstructed function did not get recovered, and 1 case occurred partially necrotic in the transplanted muscle and flap.　Conclusions　The functional free gracilis, latissimus dorsi and pectoralis minor muscle transplantation  have a satisfactory result in the reconstruction of upper limb function, which is an effective method for the treatment of various causes of upper limb muscle defects and severe limb disorders.
