Randomized Controlled Trial
[Clinical observation of ultrasound guided popliteal sciatic nerve combined saphenous nerve block for hallux valgus patients with metatarsophalangeal joint dislocation].
To explore clinical effects of ultrasound guided popliteal sciatic nerve combined saphenous nerve block in patients with anterior foot orthopedics. ⋯ Ultrasound guided popliteal sciatic nerve combined saphenous nerve block could meet demand of hallux valgus patients with metatarsophalangeal joint dislocation. Compared with lumbar anesthesia, it could maintain hemodynamic stability, prolong effective analgesia time after operation, and improve patients' overall comfort and safety for free activity above the knee joint.

Randomized Controlled Trial
[Effect of tranexamic acid combined flexion position of hip and knee on perioperative bleeding following unilateral total knee arthroplasty].
To explore clinical efficacy and safety of application of tranexamic acid for two times combined with postoperative hip and knee on flexion position for reducing blood loss during total knee arthroplasty. ⋯ The method of using tranexamic acid before upper tourniquet, after closure of incision and before loosening tourniquet-combined with the flexion position of hip and knee could effectively reduce postoperative drainage volume, recessive bleeding, total blood loss and blood transfusion cases after total knee arthroplasty, while it does not increase risk of deep vein thrombosis and pulmonary embolism.

To explore the clinical effects of Dynesys system for the treatment of multiple segment lumbar degenerative disease. ⋯ Dynesys system may obtain long-term clinical curative effect in treating multiple lumbar degenerative disease. It can partially preserve the intervertebral motions of the fixed segments, have little effect on adjacent segments. The long-term clinical effect of Dynesys still need longer time follow-up observation.

To compare the clinical effects of closed reduction and internal fixation with limited transtarsal sinus incision in the treatment of Sanders type II calcaneal fractures. ⋯ Closed reduction and internal fixation is as effective as transtarsal sinus incision reduction and internal fixation for Sanders typeIIfracture. It has the advantages of less trauma and fewer complications. Closed reduction and hollow nail fixation group can significantly shorten hospitalization time, reduce hospitalization costs, and is more economical. It is worth recommending, but attention should be paid to avoid choosing to comminute serious calcaneal fracture.

Review Meta Analysis
[Pulsed electromagnetic field therapy for the treatment of knee osteoarthritis: a systematic review].
To evaluate the clinical effectiveness of pulsed electromagnetic field therapy in the treatment of knee osteoarthritis. ⋯ The effects of Pulsed electromagnetic field therapy for treating knee osteoarthritis need more powerful trails to be confirmed. The above conclusions still need more high-quality randomized controlled trails to be verified owing to the limitations of the number and the quality of systematic review included studies.
