The first exploration of a minimally invasive lysis subcutaneouly for the treatment of gluteal muscle contracture based on relatively safe region around standard injection point of gluteal muscle / 中国骨伤

<p><b>OBJECTIVE</b>To explore the solution of choosing the minimally invasive incision site for gluteal muscle contracture patient based on standard injection point of gluteal muscle.</p><p><b>METHODS</b>from September 2008 to August 2010, 25 patients (14 males and 11 females with an average of 16.5 years, ranging from 12 to 26 years) with injected gluteal muscle contracture were prospectively studied. The course of disease was from 6 to 12 years. Firstly, the connective skin Surface line from anterior superior iliac spine to coccyx (line AD) was delineated and the point (point O) was marked out as the standard gluteal muscle injection site which was on the one-third of the distance from the anterior superior iliac spine(point A) to the coccyx (point D). Secondly, the anterior and posterior edge lines of surface projection of the gluteal muscle contracture banding (line a, line p) were delineated. Thirdly, the distance from B to O and C to O (B is the point of intersection of line a and line AD,C is the point of intersection of line P and line AD)were measured which was the intersection of line a,p and line AD to point O. Lastly, the minimally invasive surgery was operformed via the skin entry of point C.</p><p><b>RESULTS</b>OB = (0 +/- 0.76) cm, OC = (2.86 +/- 0.78) cm, BC = (2.86 +/- 1.01) cm,the mean postoperative drainage was less than 10 ml,there was no nerve damage,hematoma and other complications. All patients achieved the function of squatting in 4 to 6 days.</p><p><b>CONCLUSION</b>The solution of choosing the minimally invasive incision site based on standard injection point of gluteal muscle has advantages of positioning precisely,handling easily, recoverying quickly, less trauma and safety, etc.</p>

Preventive strategies of secondary spinal cord injury caused by subaxial cervical trauma / 中国骨伤

<p><b>OBJECTIVE</b>To summarize and analyze preventive strategies of secondary spinal cord injury caused by subaxial cervical trauma.</p><p><b>METHODS</b>From April 2004 to April 2009, 67 patients with secondary spinal cord injury caused by subaxial cervical trauma were retrospectively analyzed. There were 40 males and 20 females, with an average age of 40.5 years old ranging from 18 to 69 years. After admission the preventive strategies included using MP and GM-1, early decompression, and high pressure oxygen after operation. The neurological function was classified by Frankel, and the therapeutic effect was evaluated by total recovery rate and useful recovery rate. The total recovery rate was that the level of Frankel raise one or more grade, the useful recovery rate which included Frankel D, E was that the patient can walk by self or crutch, remaining some neurological deficits.</p><p><b>RESULTS</b>All patients were followed up for 1 to 3 years (averaged 1.5 years), the total recovery rate was 53.7% (36/67), the useful recovery rate was 35.8% (24/67). Seven patients was death, the death rate was 10.4% (7/67), 1 was aggravated, the aggravating rate was 1.5% (1/67).</p><p><b>CONCLUSION</b>As possible as using MP, GM-1, early decompression, and high pressure oxygen after operation can be effective strategies for preventing secondary spinal cord injury caused by subaxial cervical trauma.</p>
