Methods： A total of 39 patients with tibial plateau fractures were treated by arthroscopic fixation from February 2002 to December 2005, including 11 patients with bony avulsion of the anterior cruciate ligament and 19 with meniscal injury. There were 4 cases of type Ⅰ fracture, 12 type Ⅱ, 9 type Ⅲ, 12 type Ⅳ and 2 type Ⅴ according to Schatzker criteria. Firstly, the combined injuries were treated. Then the plateau fractures with the displacement over 3 mm or more were reduced and fixed. Finally, the internal fixation was observed by X-ray equipment. Postoperative management was early motion and delayed weight bearing. Results： All the fractures healed in 3 or 4 months. All patients were followed up for 1 to 5 years after operation.No case had severe complications, such as poor wound healing, infection, osteofascial compartment syndrome and osteoarthfitis. According to the Rasmussen scoring system, 36 cases obtained excellent or good results and the other 3 cases had moderate clinical results. The average score was 26 ± 3. Conclusions： As an adjuvant treatment of intraarticular fractures such as tibial plateau fracture, arthroscopy has many advantages. It can treat associated intraarticular soft tissue components, visualize the chondral surface reduction, lavage the hematoma and smaller loose fragments, decrease soft tissue dissection, reduce the risk of scarring and promote rapid recovery.展开更多

Methods： From January 2000 to October 2006, 52 patients with far-lateral lumbar disc herniation （29 males and 23 females, with the average age of 41.5 years） were treated with minimally invasive procedures. All the patients were assessed by X-ray and CT. Some were given additional myeography, discography, Computerized tomography myelography （CTM） and MRI examination. Yeung Endoscopy Spine System （YESS）, METRx and X-tube procedures were performed in 25, 13 and 14 cases, respectively. All patients were followed up for a mean period of 13.5 months. Clinical outcomes were assessed by visual analog score （VAS） and Nakai criteria. Results： The results indicated that the three procedures could significantly improve the radiating leg symptoms （P〈0.05）. The postoperative overall excellent and goodrates of YESS, METRx and X-tube procedures were 84.0%, 84.6% and 92.8% respectively, with no statistical difference among three groups （P〉0.05）. The YESS procedure had several advantages including shortest operation time, simplest anesthesia and least trauma as compared with the other two procedures, especially for simple type I far-lateral lum- bar disc herniation. METRx procedure was specially suitable for simple type II. And the procedure of posterior endoscopic facetectomy, posterior lumbar interbody fusion and unilateral pedicle screw instrumentation with X-tube was designed for far-lateral disc herniation combined with degenerative lumbar instability. Conclusion： Minimally invasive strategies and options should be determined by different types of far-lateral lumbar disc herniation.展开更多
