The Clinical Effect Of Ultrasonic Guided Closed Reduction K-Wires Transverse Internal Fixation On Metacarpal Fracture

Objective:To investigate the clinical effect of ultrasonic guided closed reduction K-wires transverse internal fixation on metacarpal fracture.Methods:Clinical data of 84 cases of metacarpal fracture admitted to our hospital from March 2017 to March 2020 were retrospectively analyzed.The observation group of 36 patients were treated with closed reduction and K-wires transverse internal fixation under ultrasound guidance,and active flexion and extension of fingers began on the first day postoperatively.X-ray was re-examined 4-6 weeks after surgery and the K-wires was removed.In the control group,48 patients received internal fixation with mini-plate under C-arm fluoroscopy,active flexion and extension functional exercise of fingers began on the first day after operation,and X-ray was reviewed at1.2.3.6 months.Results:1.Patients operated on the fracture of metacarpal bones were followed up for 12-18 months,with an average of 14.6 months.There were no serious complications such as infection,malformation or delay in healing.2.The observation group had significant advantages over the other group in operation time,intraoperative blood loss,fracture healing time and hospital stay(P < 0.001).The difference was statistically significant.3.Total motion of flexion and extension(TAM)was used to assess hand function.In the observation group,30 cases were excellent and 6 cases were good.Excellent and good rate was 100% in observation group.42 cases were excellent,6 cases were good in the control group,and the excellent and good rate of the matched group was also 100%.There was no significant difference between the two groups(P > 0.05).Conclusions:Ultrasonic guided closed reduction and K-wires transverse fixation in the treatment of metacarpal fracture is simple and easy to operate,with less radiation,less trauma,less bleeding,short operation time and fast fracture healing,especially for pregnant women and teenagers and it is worthy of clinical promotion.
