  • QUANTITATIVE EVALUATION OF POSTOPERATIVE EFFECT OF CALCANEAL FRACTURES USING FOOTSCAN SYSTEM

    Objective To investigate the value of using Footscan system to evaluate the therapeutic effect of two internal fixation methods on calcaneus fractures. Methods From February 2006 to September 2006, 64 patients with fresh unilateral closed calcaneus fractures were randomly divided into two groups. The experimental group: 32 patients underwentminimally invasive open reduction and internal fixation with improved compressing plate and screw, including 28 males and 4 females aged 20-53 years old (average 36.7 years old); the course of disease was 3-14 days; there were 19 cases of type II, 11 of type III, and 2 of type IV according to Sanders fracture classification system. The control group: 32 patients underwent internal fixation of standard AO plate via L-shaped incision, including 29 males and 3 females aged 18-56 years old (average 37.1 years old); the course of disease was 4-15 days; there were 18 cases of type II, 11 of type III and 23 of type IV according to Sanders fracture classification system. No significant difference was noted between two groups in the general information (P gt; 0.05). At 1 and 2 years after operation, dynamic plantar pressure was measured using Footscan system, Maryland foot scores of two groups was compared, and statistical analysis was performed. Results All patients were followed up for 2 years. No infection, cuticular border necrosis, and sural nerve distal end injury occurred in the experimental group, whereas in the control group, 3 patients suffered from cuticular border necrosis and recovered after dressing, and 1 patient had sural nerve distal end injury with decreased sensation in local skin. At 1 and 2 years after operation, in the control group, there were significant differences between the injured foot and the normal foot in terms of impulse, instep index, motion range of subtalar joint, lateral displacement of footplate pressure center, and calcaneal width when patients stood on both feet (P lt; 0.05), whereas in the experimental group, no significant differences were noted between the injured foot and the normal foot in terms of the above parameters (P gt; 0.05). Significant differences were noted between two groups in terms of the above parameters (P lt; 0.05). The Maryland score 1 yearafter operation was (86.74 ± 8.56) points for the experimental group and (71.24 ± 10.06) points for the control group; at 2 years after operation, it was increased to (87.35 ± 8.49) points and (72.41 ± 9.69) points, respectively, indicating there was a significant difference between two groups (P lt; 0.05). Conclusion Operative outcomes of internal fixation with improved compressing plate are superior to those of standard AO plate. Footscan system can provide a quantitative assessment on the operative effect of calcaneus fractures.

  • SHORT-TERM EFFECT OF ROTATING HINGE KNEE PROSTHESIS

    Objective To discuss shortterm effect of rotating hinge knee prosthesis. Methods From July 2002 to April 2005, 17 cases of severe knee joint deformity and instability received rotating hinge knee prosthesis for total knee arthroplasty. There were 8 males and 9 females, aging from 41 to 79 years. The left joints were involved in 10 cases and right joint in 7 cases. All patients were admitted because of pain. The course of disease was from 1 to 7 years. There were 10 cases of osteoarthritis,5 cases of rheumatoid arthritis,1 case of traumatic arthritis after operation of left femur fracture,and 1 case of traumatic arthritis with injury of anterior cruciate ligament, meniscus medialis and medial collateral ligament after operation of left fracture of tibial plateau. According to HSS(hospital for special surgery) scoring system,the preoperative score was 36 to 58 with an average of 48.6. The preoperative flexed motion range of articulation was 21° to 80° with an average of 57.4°. Results All patients were followed up from 7 months to 3 years with an average of 23.6 months. There were no complications of thrombogenesis of veins of lower extremity, pulmonary embolism, palsy of peroneal nerve, fracture, and breakage of extended knee structure. Infection occurred in 1 case at 3 months postoperatively,the prosthesis was dislodged,antibiotic-impregnated cement was filed with knee joint,twostage arthroplasty was expected. At the last follow-up,the HSS score was 78 to 98 with an average of 91.1 in 16 patients. The flexed motion range of articulation was 75° to 100° with an average of 852° at 2 weeks postoperatively. The flexed motionrange of articular was 85° to 123° with an average of 1083° at the last followup. There were significant differences in HSS score and motion range of articular between preoperation and thelast follow-up (P<0.05). Conclusion The short-term outcome of rotating hinge knee prosthesis is good and a long term followup is necessary.

  • Clinical Effect of Silver Ion Dressing Combined with Foam Dressing on Diabetic Foot Ulcers

    ObjectiveTo study the clinical effect of silver dressing combined with foam dressing in the treatment of diabetic foot ulcers. MethodsSixty patients with diabetic foot ulcer treated between January 2014 and January 2015 were selected to be randomly divided into experimental group (n=30) and control group (n=30). Patients in the experimental group (n=30) were treated with silver dressing combined with foam dressing which was changed every other day, while patients in the control group (n=30) were treated with 0.1% rivanol gauze and dressing was changed every day. The clinical effcacy of the two groups were compared and analyzed, and the wound closure index and recurrence rate were also analyzed. ResultsThe total effective rate of the experimental group was 96.7%, which was significantly higher than that of the control group (80.0%) (P<0.05), and the wound closure indexes of the experimental group on day 21 [(81.87±4.81)%] and day 28 [(97.28±3.11)%] after the beginning of treatment was significantly higher than those of the control group [(64.06±3.03)%, (86.93±6.11)%] (P<0.05), and the recurrence rate within half a year after treatment of the experimental group was 13.0%, significantly lower than that of the control group (40.0%) (χ2=4.083, P=0.043). ConclusionCompared with traditional wound treatment, silver dressing combined with foam dressing in the treatment of diabetic foot ulcers has advantages with better curative effect, less pain and lower recurrence rate. It is worth clinical promoting.

  • The effect of Cabrol in treatment of Stanford type A aortic dissection

    ObjectiveTo discuss the effect of Cabrol in treatment of Stanford type A aortic dissection.MethodsThe clinical data of patients whom were diagnosed with type A aortic dissection of Stanford in our hospital from January 2013 to January 2018 were retrospectively analyzed. All of 40 patients underwent Cabrol surgical procedure. There were 31 males and 9 females aged 26–75 (48.8±3.3) years. The surgical treatment effect of the patients was evaluated, mainly including the aortic index, the changes in cardiac function before and after operation, and the postoperative follow-up.ResultsAll the 40 patients completed the operation successfully. The diameter of ascending aorta and aortic sinus in postoperative patients were smaller than those before operation (P<0.05). Postoperative left ventricular ejection fraction and cardiac output increased, central venous pressure and left ventricular end-diastolic dimension decreased, and cardiac function indexes were significantly different from those before the operation (P<0.05). Seven patients suffered complications in postoperative follow-up including one stenting leakage, three neurological diseases and three acute renal failure. Two patients died postoperatively.ConclusionCabrol’s operation is effective in the treatment of Stanford type A aortic dissection, which can significantly improve the cardiac function of patients, simplify the anastomosis of coronary artery ostia and decrease amount of bleeding.

  • Application of scalp electroencephalogram in treatment of refractory epilepsy with vagus nerve stimulation

    Electroencephalogram (EEG) has been an important tool for scientists to study epilepsy and evaluate the treatment of epilepsy for half a century, since epilepsy seizures are caused by the diffusion of excessive discharge of brain neurons. This paper reviews the clinical application of scalp EEG in the treatment of intractable epilepsy with vagus nerve stimulation (VNS) in the past 30 years. It mainly introduces the prediction of the therapeutic effect of VNS on intractable epilepsy based on EEG characteristics and the effect of VNS on EEG of patients with intractable epilepsy, and expounds some therapeutic mechanisms of VNS. For predicting the efficacy of VNS based on EEG characteristics, EEG characteristics such as epileptiform discharge, polarity of slow cortical potential changes, changes of EEG symmetry level and changes of EEG power spectrum are described. In view of the influence of VNS treatment on patients’ EEG characteristics, the change of epileptiform discharge, power spectrum, synchrony, brain network and amplitude of event-related potential P300 are described. Although no representative EEG markers have been identified for clinical promotion, this review paves the way for prospective studies of larger patient populations in the future to better apply EEG to the clinical treatment of VNS, and provides ideas for predicting VNS efficacy, assessing VNS efficacy, and understanding VNS treatment mechanisms, with broad medical and scientific implications.
