There were 33 clients in pie-crusting team, including 15 males and 18 females aged from 26 to 58 yrs . old with the average chronilogical age of (36.06±7.93) yrs old;who were treated with inside-out, arthroscopic deep MCL pie crusting release technique with MM-Ⅱ meniscus suture package (Smith &roup (15 patients with degree 0, 10 patients with degreeⅠ, 3 patients with degreeⅡ, 0 patient with degree Ⅲ) ended up being more than pie-crusting group(28 patients with degree 0, 5 patients with degreeⅠ, 0 patient with degreeⅡ, 0 client with degreeⅢ)( The inside-out, arthroscopic deep MCL pie-crusting release to treat posterior horn of medial meniscus tear in tight medial tibiofemoral could increase working apace, shorten operation time, lower problems for MCL and obtain good medical effectiveness.The inside-out, arthroscopic deep MCL pie-crusting release for the treatment of posterior horn of medial meniscus tear in tight medial tibiofemoral could increase working apace, shorten procedure time, lower injury to MCL and acquire good medical efficacy. From January 2018 to June 2018, 40 clients just who underwent three-dimensional CT of cervical spine had been selected, including 21 males and 19 females, heighted from 165 to 180 cm with an average of (172.9±9.5) cm, aged from 38 to 55 years of age (51.1±12.8) yrs old, excluding clients with axis lamina defect and hypoplasia. Two sets of 3D printed specimens were produced from the three-dimensional CT data of cervical spine of every client, and each of than were used for the inside vitro nailing research. Based on different nail positioning techniques, in vitro experimental part of this test had been divided into guide nail positioning group and hand nail placement group, 40 pieces in each team. On top of that, the three-dimensionalmodel of cervical spine of 40 customers ended up being reconstructed on computer, and the ideal needle point information and tendency position were obtained by computer system simulation regarding the nail positioning. This can be 3D considerable difference between the accuracy of needle exit point and inclination angle of nail course between hand nail group and 3D simulation nail team ( The guide is universal, with stable framework, precise assistance, and simple operation. It could be placed with bilateral lamina screws on top of that, reducing enough time of nail positioning, avoiding collision of two method cross screws, increase the rate of dual cortex. Fundamentally, performance and safety could be enhanced.The guide is universal, with stable structure, precise guidance, and easy operation. It could be placed with bilateral lamina screws at precisely the same time, reducing the full time of nail positioning, preventing collision of two method cross screws, raise the rate of double cortex. Fundamentally, performance type 2 immune diseases and security may be improved. To explore effect and importance of Volasertib cell line lateral shut high tibial osteotomy on recovery of task of knee joint. From February to December 2018, 78 patients with knee osteoarthritis who were addressed by large tibial osteotomy for the first time had been chosen as the observation team, including 46 guys and 32 females, elderly from 55 to 73 years old with an average chronilogical age of (61.78±6.39) yrs . old, the program of disease ranged from 6 to two years with the average of (16.52±4.25) months;according to Kellgren-Lawrence (K-L) grading, 36 patients were gradeⅡand 42 patients were grade Ⅲ. Another 20 healthy people were selected as healthier team, including 13 males and 7 females, elderly from 56 to 73 yrs old with an average of (60.89±7.12) years old. The phrase of miR-146 in peripheral bloodstream had been contrasted between observation group and healthy team. In addition, patients in observation group had been followed up for a few months. The patients whose knee-joint function gone back to regular or enhanced significantly during 20%) and 175.65 (susceptibility had been 72.80%, specificity had been mycorrhizal symbiosis 69.50%). The appearance level of serum miR-146 revealed upward trend, which could control the differentiation of chondrocyte. The monitoring of miR-146 after procedure has reference value for forecasting the data recovery of bone tissue and shared purpose after procedure.The expression level of serum miR-146 showed upward trend, which may manage the differentiation of chondrocyte. The monitoring of miR-146 after procedure features research worth for forecasting the data recovery of bone and combined purpose after procedure. To compare medical effectiveness of intramedullary nail fixation following two-step closed reduction or restricted open decrease for femoral subtrochanteric fractures. Forty six customers with femoral subtrochanteric fractures were reviewed retrospectively from January 2014 to April 2020. Twenty four patients which including 16 men and 8 females, aged from 34 to 91 yrs . old with an average of (55.42±18.25) yrs old, had been treated with two step closed reduction and intramedullary nail fixation on supine position. Twenty-two clients which including 15 males and 7 females, aged from 33 to 87 yrs . old with an average of (56.31±14.77) years old, had been carried out restricted open reductionand intramedullary nail fixation. Procedure time, intraoperative blood loss, complications and fracture healing time had been recorded and compared between two groups. Postoperative Harris hip rating at 8 months ended up being applied to evalaute shared function. All patients were effectively total procedure without incision disease. All patiey treated by both practices. Two-step closed reduction and intramedullary nail fixation may be more advantageous in less injury, smaller operation time and less intraoperative bleeding.Surgical treatment solutions are the primary treatment plan for hemophilia arthritis, including synoviectomy, combined replacement and shared fusion. Synoviectomy would work for very early hemophilia synovitis, and it is divided into radiation, substance, arthroscopy, and open procedure.
