To investigate the clinical effect of atlantoaxial pedicle screw internal fixation for treatment of atlantoaxial dislocation. ⋯ Posterior approach atlantoaxial pedicle screw internal fixation have the advantages of direct screw placement, short-segment fusion, intraoperative reduction, fixation reliable, high fusion rate, and it can restablish the upper cervical vertebrae stability and help to recover the spinal cord and nerve function.
-
To explore the operative method for the treatment of syndesmosis injury in ankle fractures. ⋯ The treatment for the syndesmosis diastasis with a three-cortices screw fixation in ankle fractures is effective. Good functional outcome can be obtained with anatomical restoration of the tibiofibular syndesmosis. The repair of deltoid ligament is important for stability of the lower tibiofibular syndesmosis. Removal of the screw before weight loading should be performed to avoid possible screw breakage.
-
To observe the effectiveness of percutaneous bone marrow grafting for treatment of fractures nonunion. ⋯ Percutaneous autologous bone marrow grafting is an effective, easy and economic therapy for fracture nonunion. But stable internal or external fixation is the premise. Excessive bone defect, the gap more than 5 mm and mal-align requiring rectification is not appropriate for this therapy.
-
To evaluate clinical result of the micro-decompression procedure for lumbar spinal stenosis. ⋯ Operative treatment for lumbar spinal stenosis is focused at the areas causing symptomatic neural root compression rather than prophylactic decompression at areas of nonsymptomatic disease. The micro-decompression procedures are more likely to be well tolerated by older patients.
-
To discuss the clinical results of hook plate internal fixation for the treatment of distal traumatic injuries of clavicle,and to analysis the mechanism of the complications. ⋯ It is advocated that hook plate for the treatment of distal clavicular fractures of Neer type II and acromioclavicular dislocation of Tossy type III could provide sufficient stability to allow early functional rehabilitation, and to decrease the rate of complications.
