BACKGROUND:Closed reduction and internal fixation are mostly used to treat fracture dislocation of tarsometatarsal joint, but cannot obtain satisfactory repair effect. Redisplacement easily appeared after local sweling subsidence. Therefore, open reduction and internal fixation are actively used in the clinic to treat fracture dislocation of tarsometatarsal joint so as to restore foot function and to elevate quality of life. OBJECTIVE:To explore the clinical effect of open reduction and cannulated screw and Kirschner wire fixation for fracture dislocation of tarsometatarsal joint. METHODS:A total of 42 patients with fracture dislocation of tarsometatarsal joint in the 88 Hospital of Chinese PLA from September 2012 to September 2013 were selected and were given open reduction and cannulated screw and Kirschner wire fixation. After treatment, the recovery of patients was observed, and ankle hindfoot function was assessed with American Orthopaedic Foot and Ankle Society ankle hindfoot score. RESULTS AND CONCLUSION:A total of 42 patients were folowed up for 1-12 months. American Orthopaedic Foot and Ankle Society ankle hindfoot score results showed that there were excelent in 30 cases, good in 10 cases, and poor in 2 cases, and the 2 patients were subjected to high energy soft tissue injury. 37 patients in 4-6 months after operation started weight-bearing walking. Three patients had mild pain, a certain functional limitation, but could maintain normal walking gait. The remaining two patients complicated with traumatic arthritis, and were unable to do normal weight-bearing walking. These results show that open reduction and cannulated screw and Kirschner wire fixation can achieve good effect of anatomical reduction of fracture dislocation of tarsometatarsal joint, and improve patient’s ankle function.

Functional near-infrared spectroscopy is a non-invasive optical brain function detection technology,which can do multi-point measurement of changes on cerebral cortical area corresponding to the oxygenation of the blood hemoglobin and deoxygenated hemoglobin concentration,and then reflect the state of brain cortex function.Its greatest advantage is to allow the subjects head moving in a certain range,especially suitable for children.At present this technology could be applied to clinical pediatric,such as epilepsy,autism,attention deficit/hyperactivity disorder,neonatal disease,neurosurgery and cardiovascular surgery,etc.Functional near-infrared spectroscopy technology will have more applications in the field of research on brain function.
