Clinical effects of tranexamic acid in arthroscope for femoroacetabular impingement / 中国骨伤

OBJECTIVE@#To evaluate the clinical effects of tranexamic acid in arthroscope for femoroacetabular impingement.@*METHODS@#Totally 34 patients (34 hips) with femoroacetabular impingement underwent hip arthroscopy from June 2016 to December 2018, were randomly divided into two groups named as tranexamic acid group and control group, 17 patients in each group. In TXA group, there were 10 males and 7 females, aged from 20 to 49 years old with an average of (32.1±7.6) years old;15 mg/kg TXA was intravenous drops before operation incision performed at 10 min. In control group, there were 11 males and 6 females, aged from 20 to 49 years old with an average of (30.9±6.2) years old;100 ml normal saline was intravenous drops before operation incision performed at 10 min. Introopertaive and total bloodloss between two groups were compared. Visual analogue scale (VAS) at 3 and 7 days after opertaion were used to evaluate pain relief of hip joint. Modified Harris Hip Score(mHHS) of hip joint at 3, 6, 9 and 12 weeks after oeprtaion were applied to evaluate clinical effects.@*RESULTS@#All patients were obtained follow up over 12 weeks. Incision healed well without infection and deep vein thrombosis. There were no statistical difference in opertaion time bewteen two groups(@*CONCLUSION@#Preoperative application of tranexamic acid could effectively reduce blood loss in arthroscopy for femoroacetabular impingement, thereby improving surgical field of vision, reducing difficulty of surgical operation, which could promote early and rapid rehabilitation of hip function.

Clinical study on the early reconstruction of complex acetabular fractures / 中国骨伤

<p><b>OBJECTIVE</b>To explore the best opportunity of structure reconstruction for complex acetabular fracture in order to provide the accurate time for clinical operative treatment.</p><p><b>METHODS</b>Complex acetabular fracture patients were divided into experimental group (93 cases, 96 hips) and control group (98 cases, 101 hips) randomly according to the operative time. The operation of patients were done respectively at the 7th, 10th day after injury in experimental group and control group. The operative time, the excellent and good rate of reduction,the postoperative complications,the joint function (ache to walk,joint activity),the SF-36 were evaluated.</p><p><b>RESULTS</b>(1) The operative time of experimental group was obviously shorter than control group according to different fracture classification. (2) According to the standard of Matta' joint function and X-ray, the experimental group was better than control group. (3) The excellent and good rate of reduction in experimental group was obviously higher than control group, according to CT scan before operation and after operation.</p><p><b>CONCLUSION</b>The early structure reconstruction of complex acetabular fracture can obviously decrease operative time and complications, increase the rate of operative reduction.</p>

Core decompression and implantation of calcium phosphate cement/Danshen drug delivery system for treating ischemic necrosis of femoral head at Stages I, II and III of antigen reactive cell opsonization / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To introduce a new method using calcium phosphate cement/Danshen drug delivery system for treating ischemic necrosis of the femoral head and evaluate its curative effect.</p><p><b>METHODS</b>From May 2000 to June 2005, 48 adult patients (54 hips) with ischemic necrosis of the femoral head at Stages I, II and III of antigen reactive cell opsonization (ARCO) were treated with implantation of calcium phosphate cement/Danshen drug delivery system in the involved femoral head. The operation consisted of removal of the necrotic bone under weight-loading cartilage and the implantation of phosphate cement/Danshen drug delivery system, and all manipulations were made percutaneously through a bone tunnel in the trochanter. The functions of the hip joint were evaluated and X-ray films were taken preoperatively and postoperatively.</p><p><b>RESULTS</b>Postoperative follow-up was 45.5 months on average, ranging from 27 to 78 months. According to the evaluation criterion of "Dandong 1995" for therapeutic effect of adult ischemic necrosis of the femoral head, the therapeutic effects were excellent in 33 hips, good in 17, fair in 3 and poor in 1, with the excellent and good rate of 92.6%.</p><p><b>CONCLUSIONS</b>This method is relatively simple with little invasion. It not only improves the microcirculation of the femoral head by local application of traditional Chinese medicine, but also provides mechanic buttress in the weight-loading area to prevent collapse during repairing, which is beneficial to repair and reconstruction of femoral head. It may be a choice of minimal invasion surgery for ischemic necrosis of the femoral head at Stages I, II and III of ARCO.</p>
