Clinical applications of sternoclavicular hook plate for the treatment of sternoclavicular joint dislocation / 中国骨伤

<p><b>OBJECTIVE</b>To observe the clinical therapeutic effects of sternoclavicular hook plate for the treatment of sternoclavicular joint dislocation.</p><p><b>METHODS</b>From June 2010 to June 2012, 7 patients with sternoclavicular joint dislocation were treated with sternoclavicular hook plate fixation. Among the 7 patients, 5 patients were male and 2 patients were female, and the average age was 42.3 years, ranging from 38 to 54 years. The course of the disease ranged from 1 to 4 weeks. All the patients had trauma history. The clinical manifestations included: obvious swelling and pain of sternoclavicular joint, restricted shoulder joint activity. The sternoclavicular joint dislocation was proved by preoperative X-ray and CT. The postoperative curative effect was evaluated according to Rockwood scoring method.</p><p><b>RESULTS</b>According to Rockwood scoring method, the excellent results obtained in 6 cases, good in 1. There were no complications such as internal fixation loosening or broken, second dislocation, pain in the sternoclavicular joint, and deformity. The function of shoulder joint was good, and the limb activity was free and no pain appeared.</p><p><b>CONCLUSION</b>The sternoclavicular hook plate for the treatment of sternoclavicular joint dislocation has follow advantages: simple procedure, stable fixation, definite therapeutic effects.</p>

A short-term follow-up results of lumbar disc herniation by Coflex / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the short term effectiveness of lumbar disc herniation by Coflex.</p><p><b>METHODS</b>From December 2007 to June 2008, 31 patients (16 males and 15 females) were treated by Coflex. The average age was 51.4 years (range, 33 - 70 years). The average period of follow-up was 10 months. To evaluate the short term effectiveness of lumbar disc herniation by Coflex by JOA, VAS, the conventional radiography and oswestry disability index (ODI).</p><p><b>RESULTS</b>The average JOA score increased from 9.1 +/- 1.1 preoperatively to 26.4 +/- 1.7 at 6 month postoperatively. ODI decreased from 24.7 +/- 4.8 preoperatively to averaged 4.5 +/- 1.1 at 6 months postoperatively. The VAS score decreased from 7.9 +/- 0.8 to 3.0 +/- 0.9. The clinical symptoms after operation were improved significantly. There were statistically significant differences between the preoperative and postoperative HD (height of dorso- intervertebral discs), DS(distance across the two adjacent spinous processes), DI (distance of intervertebral foramina). The average HD increased from (7.9 +/- 1.1) mm preoperatively to (10.8 +/- 1.3) mm after operation. The average DS increased from (28.3 +/- 2.4) mm preoperatively to (36.4 +/- 1.7) mm postoperatively. The average DI changed from (18.8 +/- 1.0) mm preoperatively to (21.6 +/- 1.7) mm postoperatively. Complications occurred in 3 patients (9.6%). One case complained of persistent low back pain. One case showed opposite lower limb pain in 3 weeks after operation, and was cured after appropriate treatment. One case had the loosening of Coflex in 6 months after surgery, but did not appear related clinical symptoms.</p><p><b>CONCLUSION</b>Coflex for lumbar disc herniation can increase the HD and DI significantly, and it has positive meaning for keeping height of lumbar vertebral space and treating the nerve root symptom of lumbar disc herniation.</p>
