Objective To investigate the orthopaedic inpatients’ disease and cost constitution of the Third People’s Hospital of Chengdu during 2008-2010, so as to provide detailed baseline data for further research on the factorial analysis of disease burden and effective intervention. Methods The medical records of inpatients in orthopaedic department of the hospital during 2008-2010 were collected, and the diseases based on the first diagnosis on discharge records were classified according to the International Classification of Diseases (ICD-10). Results During 2008 to 2010, the total number of inpatients increased year by year. Most of the male inpatients were the young and middle-aged, while the female were the old. The rank order of top 5 systematic diseases didn’t change, while there were 6 single diseases kept ranking as top 10 in those 3 years. The average cost per capita averagely grew by 8.97%. The top 3 constitution of hospitalization cost remained the same, which were material cost, drug cost, and treatment cost; while the top 3 payment modes of hospitalization cost were patient’s own expense, social security, and public expense. Among those payment modes, social security rose obviously, and patient’s own expense reduced generally. Conclusion a) The total number of inpatients increases yearly during 2008-2010, and the gender and age distribution of inpatients are tending towards stability. b) The spectrum of disease and single diseases classified according to the one-level code of ICD-10 are relatively stable in those 3 years; of which the top ranked disease is lumbar disc herniation, and the disease with most obviously rising trend is intertrochanteric fracturethe. c) The hospitalization cost per capita rises year by year, of which the constituent ratio of both material and examination costs grow obviously, but the operation, treatment and bed costs are still lower. It requires a multi-pronged approach to control the increase of hospitalization cost as well as the rationalization of cost constitution. d) Among all payment modes of hospitalization cost, the constituent ratio of patient’s own expense reduces year by year, while social security rises, indicating the medical security in national social security has been further expanded.

ObjectiveTo analyze the risk factors of acute wound infection in orthopedic patients. MethodsA retrospective analysis was made on the clinical data of 576 orthopedic patients in accordance with the inclusion criteria between July and October 2012. There were 345 males and 231 females, aged 18-95 years (mean, 44 years). Single factor analysis was used for related factors, and logistic regression analysis of multi-factors for risk factors of acute wound infection. ResultsWound infection occurred in 73 of 576 patients (12.7%). Single factor analysis showed that the influence factors were gender, education, smoking history, nutritional status (hemoglobin, red blood cell count, serum albumin, and total serum protein), blood glucose level, shock history, wound situation (characteristics, multiple injuries, and cleaning), type of injuries, the time of trauma handling, antibiotic use, whether to stay in ICU, wound pain score, drug analgesia, patient controlled analgesia, and dressings and cleaning solution choice. The logistic regression analysis showed that the gender, time of trauma handling, blood glucose level, wound pain score, dressing choice, and wound characteristics were the risk factors of acute wound infection (P<0.05). ConclusionTo achieve the best results in clinical prevention of infection, these risk factors (gender, the time of trauma handling, blood glucose level, wound pain score, dressing choice, and wound characteristics) should be considered well.
ObjectiveTo investigate the effectiveness of the Ilizarov technique for the treatment of traumatic talipes equinovarus so as to provide the evidence for the clinical practice. MethodsBetween February 2011 and April 2012,42 patients with traumatic talipes equinovarus received treatment by Ilizarov technique,including 29 males and 13 females aged 17-55 years (mean,34.3 years).The left side was involved in 24 cases,and the right side in 18 cases.The disease duration was 6 months to 6 years (mean,2.7 years).According to the principles of Ilizarov,a ring external fixator was applied on the affected foot and lower leg.The threaded rods and screw nuts were revolved according to the tolerance of patients at 3-7 days after fixation.At first,forefoot varus or foot inversion was corrected,and then drooping feet deformity was corrected.The patients were encouraged to begin weight-bearing walking after correction.X-ray films were taken regularly to observe the ankle joint and avoid its dislocation.The external fixator was maintained in neutral position for 8-12 weeks after achieving satisfactory correction.An walking ankle-foot orthosis and a sleeping ankle-foot orthosis were used for more than 16 weeks after removal of the fixator.The outcome was assessed with American Orthopaedic Foot and Ankle Society (AOFAS) comprehensive scoring system and visual analogue scale (VAS) pain score. ResultsForty-two patients were followed up 14.3 months on average (range,10-24 months).All the patients achieved 0° dorsiflexion at 4-13 weeks (mean,6.8 weeks) after treatment with Ilizarov apparatus.The fixator was maintained for 10.7 weeks on average (range,10-16 weeks) after correction.No dislocation of the ankle joint and no damage to nerves and blood vessels occurred.The deformity of plantar flexion (10°) was found in 3 patients.At last follow-up,the patients could walk normally.AOFAS score was significantly increased to 93.4±8.0 from 52.7±10.1 at preoperation (t=-7.035,P=0.008);according to AOFAS scoring system,24 cases were grades as excellent,14 as good,2 as moderate,and 2 as poor,and the excellent and good rate was 90.5%.The VAS score of the foot significantly decreased to 3.51±1.44 from 7.55±1.39 at preoperation (t=-0.564,P=0.025). ConclusionIlizarov technique combined with non-fusion has satisfactory effectiveness in correction of traumatic talipes equinovarus.It is a safe,effective,and minimally invasive method.

ObjectiveTo summarize the research and application progress of magnesium and magnesium alloys implants in the orthopedics. MethodsThe domestic and foreign related literature about the research progress and application of magnesium and magnesium alloys implants in the orthopedics was reviewed. ResultsCurrently approved and commonly used metallic implants in orthopedics include stainless steels, titanium alloys, and chromium alloys having many disadvantages of poor biocompatibility, mismatch with the biomechanical properties of the bone tissue, and need of second surgical procedure to remove. Compared with traditional implants, magnesium and magnesium alloys have biomechanical properties closer to natural bone tissue, and in vivo degradation, which have the potential to serve as new biocompatible and degradable implants. Although magnesium and magnesium alloy materials have their own advantages, but the degradation rate is still too fast and so on. At present, the research and development of medical magnesium and magnesium alloy materials are to improve their corrosion resistance and control the rate of degradation. ConclusionMagnesium and magnesium alloys have great potential as a implant material in the orthopedics, through further systematic and in-depth study, it is expected to become a new generation of degradation biological implant materials.
