Treatment of fractures of tibia intercondylar eminence under arthroscopy using suture anchors / 中国骨伤

<p><b>OBJECTIVE</b>To explore a new technique of reduction and internal fixation for tibia intercondylar eminence fractures under arthroscopy.</p><p><b>METHODS</b>From June 2004 to February 2006, 9 patients with fresh tibia intercondylar eminence fracture (type II in 4 cases and type III in 5 cases) were treated with reduction and internal fixation using suture anchors (Depuy Mitek) under arthroscopy. All the patients, subject to regular post-operation functional exercise, were followed up for 6 to 22 months. The results were evaluated in the aspects of fracture reduction healing, knee joint relaxation and ROM, and functional restoration of overall limbs.</p><p><b>RESULTS</b>In the nine patients, the tibia intercondylar eminence fractures healed without displacement and nonunion. No knee joint relaxation or extension-restriction was found. Lysholm score indicated 93.8 +/- 2.3 at the 6th postoperative months.</p><p><b>CONCLUSION</b>The reduction and internal fixation of tibia intercondylar eminence fractures under arthroscopy using suture anchors demonstrate a reliable and easy-to-use technique. Operation under arthroscopy helps diagnose and treat other complications inside knee joint, merely resulting in slight injury. In addition,early functional exercise contributes to rapid recovery of knee joint's functions.</p>

Case-clinical studies on three different intervertebral fusion with bone graft and internal fixation in the treatment of cervical spondylotic myelopathy / 中国骨伤

<p><b>OBJECTIVE</b>To evaluate the therapeutic effects of three different intervertebral fusion with bone graft and internal fixation in the treatment of cervical spondylotic myelopathy.</p><p><b>METHODS</b>In the retrospective study, 83 patients (38 males and 45 females, with an average age of 69 years) with cervical spondylotic myelopathy were divided into three groups. The patients in three groups were treated by autogenous iliac bone grafting (Robingson grafting) with anterior cervical plate-screw fixation, Pyramesh with anterior cervical plate-screw fixation and BAK fixation respectively. JOA scores and the bony fusion time were recorded and the results were evaluated by numeric computer system.</p><p><b>RESULTS</b>The JOA scores of all the patients were higher than those before surgery (t = 1.55, P < 0.05). There were no statistical difference of JOA scores in the three groups (F = 2.51, P > 0.05).</p><p><b>CONCLUSION</b>It is concluded that internal fixation of the three types is promising to the treatment of cervical spondlotic myelopathy. Robingson grafting with anterior cervical plate-screw fixation provides good stability and bony fusion. BAK is better technically required but there was height loss in clinic. Pyramesh with anterior cervical plate-screw fixation combines the merits of both two techniques above but the cost is higher.</p>
