Abstract:
OBJECTIVE: To investigate the efficacy of autologous peripheral blood mononuclear cells in the treatment of high radial nerve injury. METHODS: From April 2011 to September 2015, 12 cases of radial nerve injury in the middle arm were treated. Preoperatively peripheral blood mononuclear cells were mobilized, and then 15 mL of mononuclear cell suspension was prepared on the operation day. Radial nerves scheduled for anastomosis were surgically explored and subjected to end-end anastomosis using outer membrane suturing under microscope. The anastomotic site of the nerve was enveloped with gelatin sponge soaked with 5 mL of autologous peripheral blood mononuclear cell suspension. The remaining 10mL of cell suspension was used for a multi-point injection into the local muscles, 0.5 mL at each point. Thereafter, the deep fascia and the incision were sutured in sequence. Postoperative antibiotic treatment was used to prevent infection for 48 hours, and upper limb immobilization lasted for 4 weeks. Performance of rehabilitation exercise was guided. During the follow-up, wrist dorsal extension and muscle strength of extensor carpi ulnaris and extensor digitorum communis were detected to evaluate the therapeutic efficacy. RESULTS AND CONCLUSION: All the patients were followed up for 15 to 36 months, with an average of 17 months. Efficacy was excellent in 9 cases, good in 2 cases, fair in 1 case and poor in 0 case. The excellent and good rate was 92%. The wrist dorsal extension could achieve the functional needs, and the thumb dorsal extension and finger extension basically met the functional requirements. It is suggested that autologous peripheral blood mononuclear cell transplantation can achieve good outcomes in the treatment of high radial nerve injury.
