Comparison of clinical efficacy of two different arthroscopic release methods for the treatment of primary frozen shoulder / 中国骨伤

OBJECTIVE@#To compare clinical effects of inside-out technique and outside-in technique for the treatment of idiopathic frozen shoulder under arthroscopy.@*METHODS@#From April 2015 to July 2019, 65 patients with primary frozen shoulder were divided into observation group and control group according to different treatment methods. In observation group, there were 32 cases, including 14 males and 18 females, aged 48 to 64 (54.82±5.35) years old, 18 cases on the right side and 14 cases on the left side. The course of disease was 4 to 10 (7.76±1.19) months. The patients were treated with outside in technique. In control group, there were 33 cases, 16 males and 17 females, aged 45 to 62 (54.64±4.16) years old, 18 cases on the right side and 15 cases on the left side. The course of disease was 5 to 9 (7.65±1.24) months. The patients were treated with inside out technique. The operation time, hospitalization days and treatment cost were compared between the two groups. Constant-Murley function score before and after the operation andthe shoulder joint range of motion one month after operation were compared to evaluate the clinical efficacy.@*RESULTS@#All 65 patients were followed up for 9 to 17 months with an average follow up time of (11.34±2.24) months. Compared with control group, operation time in observation group was shorter[(55.53± 10.23) min vs (85.58±13.39) min], and functional scores of Constant-Murley after surgery were significantly changed in both groups compared with that before surgery(@*CONCLUSION@#The two arthroscopic release schemes have achieved satisfactory results for thetreatment of primary frozen shoulder, and the shoulder joint function and pain degree have been effectively improved. Compared with the inside-out technique, the outside in release technique is more direct, the operation is simpler and the operation time is shorter. It has certain advantages in releasing operation for primary frozen shoulder.

Clinical observation of iron sucrose combined with recombinant human erythropoietin in the treatment of anemia of hip fracture in elderly patients / 中国骨伤

OBJECTIVE@#To explore the clinical efficacy of iron sucrose combined with recombinant human erythropoietin(EPO) for the treatment of anemia in elderly patients with hip fracture.@*METHODS@#From February 2016 to April 2018, 96 elderly anemia patients who underwent hip fracture surgery were divided into three groups according to the treatment methods. All the three groups received anti-anemia treatment 3 days before operation. Among them, 32 cases in group A were treated with iron sucrose alone, 32 cases in group B were treated with recombinant human erythropoietin alone, and 32 cases in group C were treated with iron sucrose combined with recombinant human erythropoietin. The therapeutic effects of the three groups were observed and compared.@*RESULTS@#The clinical effective rate in group C was significantly higher than that in group A and B (0.05), but the transfusion rate in group C was significantly lower than that in group A and B (0.05), but the above indexes in group C were significantly higher than those in group A and B(0.05).@*CONCLUSIONS@#Compared with single drug, the combined use of sucrose and iron and recombinant human erythropoietin in the treatment of elderly hip fracture anemia has a definite effect. It can not only effectively improve the level of hemoglobin, ensure the smooth operation, but also reduce the blood transfusion rate of patients and promote their recovery after operation.

Clinical value of the ECT bone scan in diagnosis of prosthesis infection for revision / 中国骨伤

<p><b>OBJECTIVE</b>To detect the clinical value of the ECT bone scan in evaluating of the situation of infection control after hip knee arthroplasty.</p><p><b>METHODS</b>The clinical data were retrospectively analyzed in 62 patients, including 34 males and 28 females with an average age of 68.8 years old ranging from 65 to 74 years. The results of ECT bone scan, erythrocyte sedimentation rate, C-reactive protein were used to assess periprosthetic infection. The patients with positive ECT and ESR on CRP were considered to have periprosthetic infection; however, the patients with two or more negative, indexes were considered to have no infection.</p><p><b>RESULTS</b>The sensitivity, specificity, accurate rate of ECT were 75.0%, 88.9%, 87.1% respectively; ESR 50.0%, 72.2%, 69.4%; CRP 62.5%, 81.4%, 79.0%. The combination of the three methods were 87.5%, 96.3% and 95.2%,</p><p><b>CONCLUSION</b>Compared with ESR and CRP, ECT is a more effective way in the diagnosis of periprosthetic infection, which has great value and is worth popularizing.</p>
