ABSTRACT
Objective:To investigate the clinical effect of percutaneous curved kyphoplasty in the treatment of old osteoporotic vertebral body with endplate fracture.Methods:Clinical data of 58 patients suffering from old osteoporotic vertebral bodies with endplate fractures from January 2018 to January 2020 were analyzed retrospectively. All patients had a single vertebral body fracture and were treated with bilateral injection of bone cement with percutaneous kyphoplasty (PKP). According to the shape of the puncture device, the patients were divided into a curved needle group and a ordinary group. There were 28 cases in the curved needle group, including 7 males and 21 females, aged 60-84 years old, with an average age of 71.8±7.8 years. The distribution of vertebral bodies with fractures: T 11 3 cases, T 12 5 cases, L 1 6 cases, L 2 5 cases, L 3 3 cases, L 4 4 cases, and L 5 2 cases. In the ordinary group, there were 30 cases, 8 males and 22 females, with an average age of 73.2±8.4 years (range, 61-88 years). The vertebral body distribution of fracture: T 11 3 cases, T 12 5 cases, L 1 7 cases, L 2 4 cases, L 3 4 cases, L 4 5 cases, and L 5 2 cases. The surgery time, amount of bone cement injection, and bone cement leakage rate were compared between the two groups, as well as the visual analogue scale (VAS) and Oswestry disability index (ODI) at 1 week, 6 months, and 1 year after surgery. Preoperative and postoperative vertebral midpoint height and kyphosis Cobb angle were measured. Results:All patients were followed up for 12-24 months, with an average of 14.7±2.9 months. The bone cement leakage rate in curved needle group (18%, 5/28) was lower than that in ordinary group (23%, 7/30), but there was no significant statistical difference (χ 2=0.27, P=0.607). The amount of bone cement injection and surgery time in curved needle group (5.0±0.5 ml, 55.2±6.9 min) were significantly higher than those in ordinary group (3.4±0.6 ml, 42.9±3.6 min, P<0.05) . The scores of VAS (2.3±1.0, 2.6±1.5) and ODI (27.5%±9.7%, 28.7%±11.3%) in curved needle group were lower than those in ordinary group (2.7±1.0, 4.5±1.1 and 31.8%±10.5%, 43.1%±13.4%) at 6 months after surgery and at the last follow-up after surgery. In the curved needle group, the Cobb angle was 25.5°±3.5° preoperatively, 18.4°±1.6° postoperatively, and 20.5°±4.9°at the last follow-up. The height of the vertebral body was 14.2±1.9 mm before surgery, 21.5±2.2 mm after surgery, and 20.1±3.6 mm at the last follow-up. Compared with the preoperative results, the kyphosis Cobb angle decreased and the height of the fractured vertebral body increased at the last follow-up, and the differences were statistically significant ( P<0.05). In the ordinary group, the Cobb angle was 24.4°±3.6° preoperatively, 23.1°±4.0° postoperatively, and 27.8°±2.9° at the last follow-up. The height of the vertebral body was 14.5±1.8 mm before surgery, 15.4±2.0 mm after surgery, and 12.7±1.0 mm at the last follow-up. At the last follow-up, the kyphosis Cobb angle increased and the height of the fractured vertebral body decreased compared with preoperative and postoperative 1 week, and the differences were statistically significant ( P<0.05). At 1 week after surgery, 6 months after surgery and the last follow-up, the Cobb angle of curved needle group was lower than that of ordinary group ( P<0.05), the height of vertebral body was higher than that of ordinary group ( P<0.05). Conclusion:Flexible application of percutaneous curved kyphoplasty in the treatment of old osteoporotic vertebral body with endplate fractures can effectively increase the riveting force of bone cement in the vertebral body, restore the height of endplate, and reduce the occurrence of kyphosis and chronic low back pain.
ABSTRACT
Objective To investigate the clinical characteristics of posterior malleolar ankle fracture, and the selection of the surgical approach. Methods From January 2013 to September 2015, 83 cases of posterior malleolar fractures were retrospectively analyzed. Haraguchi typing was performed based on the three-dimensional CT. There were 54 cases with HaraguchiⅠtype, 16 cases with HaraguchiⅡtype, and 13 cases with HaraguchiⅢtype. The patients who were HaraguchiⅠand Haraguchi Ⅲtypes accepted the operation with posterolateral approach. The patients who were HaraguchiⅡtype and combined medial malleolus fracture accepted the operation with medial approach. The HaraguchiⅡpatients who were not combined medial malleolus fracture were used the medial paraachilles approach. Images of the ankle joint were filmed 2 weeks, 4 weeks, 12 weeks, 6 months and 12 months after the surgery. The healing time, complications and corresponding record outcome were determined by X-ray and clinical examination. At the last follow-up, ankle function and quality of life of patients were evaluated according to the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and SF-36. Results Eighty-three patients were follow-up for 6-24 (mean 15.4± 6.2) months. The fractures healed on X-ray. The average X-ray healing time was from 12 to 24 (mean 18.6±4.2) weeks. AOFAS score was 71 to 100 (mean 88.4±8.4) points. Sixty-seven cases were excellent, 14 cases were good, 2 cases were moderate, and good rate was 97.59%. SF-36 physiological score was 31.6-69.2 points(mean 48.4 ± 4.8 points);SF-36 psychological score 28.6-64.5 points(mean 45.8 ± 3.5 points). Chronic ankle pain was complained by one patient. He was diagnosed traumatic arthritis, oral non-steroidal drugs was used to relief his ankle pain. One patient wound infected, and healed after treatment. No instrument failure and fracture displacement were found. Conclusion According to fracture morphology and clinical features after posterior malleolar ankle fracture, different surgical approaches are selected, which will be satisfied with the outcome.

ABSTRACT
Objective To explore the early clinical efficacy of posteromedial approach for treatment of posterior bicondylar tibial plateau fractures.Methods From October 2010 to December 2013,data of 13 patients of posterior bicondylar tibial plateau fracture who were treated with plate and screw fixation through posteromedial approach were retrospectively analyzed.There were8 males and 5 females,in which 7 cases located in the left knee and 6 cases located in the right knee,with an average age of 41.5±6.6 years.An inverted L shaped posteromedial incision was made in the operation.If the fracture line was involving the posteromedial condyle,a locking anatomical plate or L shaped compression plate was used.A 3.5 mm T shaped plate was used to support the posterolateral condyle.Allogeneic bone was used to support the articular surface in the cases with obvious bone defect.Rasmussen score was used for radiological assessment,and HSS knee score was used for efficacy assessment 12 months postoperative.An anteroposterior view and lateral view of the knee were obtained 2,4,12 weeks,6 months and 12 months postoperation.The fracture healing time was judged by X-ray and clinical examinations,additionally,the complications and corresponding outcomes were also recorded.Results All 13 patients had obtained an average of 20.8±9.4 months follow-up (range,8-34 months),and all fractures were healed.The healing time in terms of X-ray was 12 to 24 weeks (mean,15.6±5.2 weeks).After surgery,the Rasmussen score was 1-18 points (mean 15.8 points).7 cases achieved excellent results,4 good,and 2 fair.The excellent and good rate was 84.6％.HSS knee score improved significantly from 38.2±7.8 points (range,26-48 points) to 85.2±7.8 points (range,56-92 points) 12 months postoperation,and the results was excellent in 9 cases,good in 2,fair in 1 and poor in 1,with total excellence and good result of 84.6％.The range of knee activity was 95°-130°.None of the skin and soft tissue complications such as infection,breakage of screw loosening occurred at the time of the latest follow-up,but two cases got chronic pain in the knee postoperation.In the follow-up period,a mild knee gap narrows had been observed in one patient and traumatic arthritis was diagnosed.The pain was partial relieved by oral non-steroidal drugs and intra-articular injection of Sodium Hyaluronate.The other one's pain was significantly relieved by oral non-steroidal drugs,and X ray film shows the knee joint gap has no obvious narrow.Conclusion Posteromedial approach for treatment of posterior bicondylar tibial plateau fractures can obtain a satisfactory therapeutic effect.
ABSTRACT
Objective To explore the relationship between the expression changes of cytokines, inter-leukin-6(IL-6), interleukin-8(IL-8), and tumor necrosis factor-α (TNF-α), and the wound time following explosive injury to rabbit’s chest. Methods The rabbit’s model of explosive injury was established. The expression levels of IL-6、 IL-8 and TNF-α in the plasma were detected by ELISA method at different wound time (0.5-12 h). Results The level of IL-6 increased at 3 h after wounding and reached peak at 6 h. The level of IL-8 increased at 1 h and reached peak at 6 h. The level of TNF-α increased at 0.5 h and reached peak at 3 h. Conclusion IL-6, IL-8 and TNF-α have a time-related expression after explo-sive injury.
ABSTRACT
Objective To investigate the feasibility of determining the surface density of RGD-containing peptide on allogenic bone by isotopic tracing technique using RGD peptide labelled with 125Ⅰ,and the impact of the input concentration of RGD-containing peptide on the surface density,and to obtain the history between the surface density and the input concentration of RGD-containing peptide.Methods The synthetic RGD-containing peptide was labelled with 125Ⅰ,and the specific radioactivity was calculated.The reactive solutions of RGD-containing peptide with the radioactive 125Ⅰ-RGD as a probe were prepared at the input concentrations of 0.01 mg/ml,0.10 mg/ml,0.50 mg/ml,1.00 mg/ml,2.00 mg/ml,4.00 mg/ml.Using EDC as the cross-linking agent,the reaction was carried out by placing the allogenic bone pieces into the reactive solutions of RGD-containing peptide with different input concentrations.After the reaction,the surface density of RGD-containing peptide grafted onto the allogenic bone pieces was calculated by evaluating the radioactivity and the surface area of the bone pieces.The impact of the input concentration of RGD-containing peptide on the surface density was measured and the curve was ascertained.Results After measuring in the radiodensity γ-counter,the result showed the RGD peptides have been marked with 125Ⅰ successfully.The allogenic bone pieces were radioactive after the reaction,which demonstrated that the RGD-containing peptide had been grafted onto the surface of bone pieces successfully.It was also found that with the increasing of input concentration,the surface density raised.Conclusion The surface density of RGD-containing peptide is related to its input concentration.With the increasing of input concentration,the surface density raises to the saturation value gradually.
ABSTRACT
Objective To explore the diagnosis and treatment of altitude sickness combined with urinary retention. Methods 30 cases of altitude sickness combined with urinary retention were treated from April 16th to 26th,2010.They were all male,The average age of them was 24 years (range,19 -38).All were the first time entering the high altitude area (3600 -5000 m) from low altitude area (600 - 1800 m ).The urinary frequency of 25 patients reduced from 8 to 10 times/d to 2 to 4 times/d,the urine output reduced from the 1500- 2400 ml/d to 600- 800 ml/d; the other 5 patients had no urine in 12 -18 h,even had no sense to urinate.26 patients also combined with altitude pulmonary edema and 4 combined with altitude cerebral edema.30 patients had double renal columns enlarged,21 cases had urinary protein ( + ～ ++ ). Results 30 patients were exported urine 300 -600 ml within 10 min,leaded to urine 1800 -2300ml in 12 h,returned to normal voiding after catheter removal in 18 -24 h. After comprehensive treatment such as oxygen,dehydration,diuretic,sedative,antispasmodic and anti-infection,22 cases who with chest tightness,shortness of breath,dyspnea,hemoptysis foam sputum,headache,vomiting and other symptoms of jet-like improved apparently after hospital admission within 1 hour.Their heart rate downed from 90 - 145beats/min to 68 -92 beats/min,respiration from 28 -45 times/min to 18 - 28 times/min,oxygen saturation from 48％ - 84％ to 92％ - 100％ ; 8 cases who with shortness of breath,palpitation and headache improved not obviously.After the antihypertensive treatment,their blood pressure was still high (systolic blood pressure 150 - 180 mm Hg,diastolic blood pressure 90 -110 mm Hg),oxygen saturation between 78％ to 87％,so they were carried to rear area for further treatment.30 cases were all cured no death. Conclusions The high altitude urinary retention is reversible disease,which is often associated with high altitude pulmonary edema,altitude cerebral edema,acute subclinical renal dysfunction and gastrointestinal disorders.They are easily being induced by elements such as gastroenteritis,lung infection,tonsillitis,periodontitis,tiredness and so on; low atmospheric pressure,hypoxia and high altitude is the possible cause; the ratio of missed diagnosis is high; the treatment of oxygen and indwelling catheterization is better; The best method of prevention is to wear pressurized suits and adapt the environment in a ladder-step gradual way.
