Randomized Controlled Trial
[Observation of the efficacy of local multimodal analgesic drugs injection in total hip arthroplasty].
To study the efficacy of periarticular multimodal analgesic drugs injection in total hip arthroplasty. ⋯ Periarticular injection of multimodal analgesic drugs in total hip arthroplasty can significantly reduce the postoperative pain of patients and the consumption of patient-controlled analgesia.
-
To study the clinical results of surgery for rotationally and vertically unstable pelvis fracture. ⋯ In the management of the rotationally and vertically unstable pelvis fractures, a stable pelvis can be reconstructed by effective open reduction and internal fixation through the anterior approaches, so that further sequelae can be reduced.
-
To study the value of imaging diagnose and clinical meaning for easy neglect occult posterior pelvic ring injury. ⋯ MPR CT could detect imperceptible fractures not been seen on AP view of CR of posterior pelvic ring and visualized sacral fractures better than the axial source images. MPR CT is accurate and reliable in occult posterior pelvic ring fracture for correct fracture detection and classification and guide therapeutic decision-making in patients with pelvic ring trauma.
-
To discuss feasibility of minimal-invasive surgical treatment of the pelvis fractures. ⋯ Minimally invasive operation has the merit of short operation time, fine effect, soon recovering and few complication.
-
To compare the clinical effect of rotary self-locking intramedullary nail (RSIN) and intramedullary interlocking nail (IIN) for the treatment of fresh femoral shaft fracture. ⋯ IIN provides a reliable and practical alternative method for the treatment of all kinds of femoral shaft fracture and its important complication is fewer than RSIN group. RSIN also has a good curative effect in its own indication.
