ABSTRACT
BACKGROUND:Distal radius C fractures belong to multiple fractures in the joint. Its treatment should recover various angles and joint surface continuity outside the joint. The recovery of palmar tilt angle, radial inclination angle and radial height is also very important for treating distal radius. OBJECTIVE:To study the changes in palmar tilt angle, radial inclination angle and radial height after type C fractures of the distal radius repaired with Acu-Loc(R)2 VDR bone plate system. METHODS:From May 2015 to March 2016, 11 cases of type C distal radial fractures were treated with Acu-Loc(R)2 VDR bone plate system. Preoperatively, the palmar tilt angle was-31° to-4° (-12.45° on average), and the radial inclination angle was 6° to 18° (11.18° on average), and the radial height was 1.92 mm to 8.68 mm (5.28 mm on average). X-ray films were observed at postoperative 4, 8 and 12 weeks and half a year in all patients. Palmar tilt angle, radial inclination angle and radial height were measured and observed using anteroposterior and lateral X-ray films during final follow-up. Wrist function was assessed with Gartland-Werley score. RESULTS AND CONCLUSION:(1) 11 patients were followed and the postoperative follow-up ranged from 7 months to 15 months. X-ray films showed that the union of fractures was achieved in 6-8 weeks (6.5 weeks on average). No infection or internal fixation failure occurred. The articular facets were smooth in 10 patients and a little poor was found in 1 case (<2 mm). (2) After operation, the palmar tilt angle was 8° to 15° (11.55° on average) (P<0.05);the radial inclination angle was 22° to 27° (23.18° on average) (P<0.05);the radial height was 8.01 mm to 13 mm (11.03 mm on average) (P<0.05). (3) The results were excellent in 8 cases, good in 2 cases, and poor in 1 cases according to Gartland-Werley wrist function assessment;the excellent and good rate was 91%. (4) Acu-Loc(R)2 VDR bone plate fixation can provide reliable fixation and effective support for type C distal radius fractures, which can recover the palmar tilt angle, the radial inclination angle and the radial height, so the Acu-Loc(R)2 VDR bone plate is an ideal method to treat type C fractures of the distal radius.
ABSTRACT
Objective To study the importance of radial height restoration in the type C distal radial fractures and selection of therapeutic method.Methods Sixty-one cases of type C distal radial fractures in the department of joint orthopedics and traumatic orthopedics of affiliated traumatic and orthopedic hospital of Guangzhou university of Chinese medicine from June 2013 to September 2015 were retrospectively analyzed, including 34 cases of C1 type,14 cases of C2 type and 13 cases of C3 type according to the AO/ASIF fracture classification, the cases were divided into the manual reduction and splint external fixation group (27 cases), external fixator group (18 cases) and plate screw internal fixation group (16 cases).The radial height, palm inclination angle, ulnar inclination angle and Gartland-Werley (G-W) score after treatment were compared among various groups.Results Fifty-eight cases were followed up.The radial height, ulnar inclination angle and G-W score had statistical difference among 3 groups (P0.05);the difference of radial height and ulnar inclination angle between the external fixator group and plate screw internal fixation group had no statistical significance (P>0.05), but there were statistically significant differences when these two groups were compared with the manual reduction and splint external fixation group respectively (P0.05) , but there were statistically significant differences when these two groups were compared with the the plate screw internal fixation group respectively (P<0.05).Conclusion The radial height restoration may better recovery ulnar inclination angle and improve the joint function.
ABSTRACT
BACKGROUND:Tranexamic acid is extensively used in the primary total knee replacement, but there are many different methods. OBJECTIVE:To explore the efficacy and safety of the intra-articular injection of tranexamic acid with pressurization in reducing the blood loss of primary total knee replacement. METHODS:Total y 56 patients undergoing unilateral total knee arthroplasty were enrol ed and randomly divided into two groups. Patients were given the intra-articular injection of 100 mL of saline solution dissolving 2.0 g of tranexamic acid with large pad pressure bandaging the knee, and 4-hour drainage tube close, and then underwent negative pressure suction (experimental group);differently, the controls were given the normal pad bandage group. The drainage tube was removed within 48 hours after replacement. The patient blood routine examination was performed at the 3rd day, and at the same time, the volume of drainage was recorded;and the color Doppler ultrasound in ipsilateral lower extremity veins was conducted to observe the incidence of thrombosis at 4-5 days. RESULTS AND CONCLUSION:(1) The total blood loss, postoperative dominant blood loss, and hidden blood loss in the experimental group were significantly less than those in the control group (P0.05). (3) These results indicate that the intra-articular injection of tranexamic acid with pressurization can significantly reduce the postoperative blood loss in the primary total knee arthroplasty, without increasing the risk of deep vein thrombosis.
ABSTRACT
Objective To explore the effect of improved surgical method of intramedullary fibular allograft together with cannulated screw fixation combined with blood-activating and stasis-resolving Chinese medicine on the quality of life (QOL) of young and middle-aged fresh femoral neck fractures at intermediate stage. Methods A retrospective analysis was carried out in the articular orthopedics department of the First Affiliated Hospital of Guangzhou University of Chinese Medicine. The study involved 80 cases of young and middle-aged fresh femoral neck fractures receiving intramedullary fibular allograft together with cannulated screw fixation, and 50 qualified cases receiving cannulated screw fixation alone ( control group) . After the operation, all of the patients were given oral use of blood-activating and stasis-resolving Chinese medicine. After the last follow-up, Harris hip scoring, SF-36 scoring and radiographic evaluation were performed for the evaluation of clinical efficacy. Results The clinical application of intramedullary fibular allograft together with cannulated screw fixation combined with Chinese medicine was fulfilled in 80 hips of 80 cases. The follow-up period ranged from 48 to 84 months, averaging 62.68 ± 12.43 months. The improved surgical method group had an excellent and good rate of 93.75%, presented excellent-grade Harris scores and SF-36 scores, and had higher QOL scores than the control group (P<0.05) . After treatment, the two groups had statistically significant differences in the scores of SF-36 items of physical function ( PF) , bodily pain ( BP) , mental health ( MH) , vitality ( VT) , and general health ( GH) ( P<0.05 or P<0.01) , and also had significant differences in Harris scoring of pain, function and daily activities as well as the joint range-of-motion ( P<0.05 or P<0.01) . Conclusion The improved surgical method of intramedullary fibular allograft together with cannulated screw fixation combined with blood-activating and stasis-resolving Chinese medicine shows satisfactory therapeutic effect for young and middle-aged fresh femoral neck fractures at intermediate stages, which has the advantages of lower collapse rate after femoral head necrosis, less joint replacement, higher scores of the quality of life and Harris scoring, and better radiographic indicators than cannulated screw fixation alone.
