Comparative Study
[Two different fixation methods combined with lumbar interbody fusion for the treatment of two-level lumbar vertebra diseases: a clinical comparison study].
To investigate the advantages and disadvantages of unilateral pedicle screw fixation combined with contralateral translaminar facet screw fixation and interbody fusion with cages in the treatment of two-level lumbar vertebra diseases, by comparing bilateral pedicle screw fixation and interbody fusion with cages. ⋯ Compared to bilateral pedicle screw fixation and lumbar interbody fusion with cages, unilateral pedicle screw fixation combined with contralateral translaminar facet screw fixation and lumbar interbody fusion with cages shows advantages including small skin incision, minimal invasion, ease of operation, highly reliable stability, high interbody fusion rate, rapid recovery in the treatment of two-level lumbar vertebra diseases and therefore can be preferred as a treatment method of this disease.

To introduce a technique pertaining to S2 iliosacral screw insertion. ⋯ The S2 iliosacral screw insertion technique is safe and reproducible to guide the placement of the S2 screw, enhancing the stability for the compromised posterior pelvic ring.

Total knee arthroplasty has become one of the effective operation methods on end-stage knee osteoarthritis. However,the postoperative pain has been plaguing the clinicians. ⋯ Pain treatment in perioperative period includes preoperative education, analgesia in advance, and the selection and design of reinforcement; during operation mainly includes the appropriate surgical approach, keep the balance of soft tissue around the knee joint, cocktail analgesia pain around the knee joint; after operation mainly includes oral analgesic drugs, femoral nerve tissue and patient controlled analgesia. And the multimodal analgesi.a which is the analgesic methods combined application in perioperative period raised in resent years fully intervene the pain in perioperative period,so that it can effectively reduce the pain of patients after knee replacement, promote the patients do functional exercise more better and get better operation result.

To systematically evaluate the efficacy and safety of preoperative administration of cyclooxygenase-2 (COX-2) inhibitor on pain occurring with total knee arthroplasty (TKA). ⋯ The current evidence indicated that preoperative administration of COX-2inhibitor can effectively improve the effect of postoperative analgesia, reduce the consumption of morphine and lessen the incidence of pruritus. Due to the limited quantity of the included studies and the evidence with limited strength,further high-quality RCTs are needed to verify the aforementioned conclusion.

Comparative Study
[Comparison among three cannulated screws and dynamic hip screw combined with antirotation screw for comminut- ed fractures of femoral neck].
To compare the effect of three cannulated screws and dynamic hip screw (DHS) combined with antirotation screw in treating patients with comminuted fractures of femoral neck. ⋯ The DHS combined with antirotation screw is superior to three cannulated screws for treatment of comminuted fractures of femoral neck due to earlier weight-bearing, faster fracture healing and better hip function
