Diagnostic analysis of the radiologic characteristics in osteoporotic Kiinmmel's disease / 中国骨伤

<p><b>OBJECTIVE</b>To explore the diagnostic value of the radiologic characteristics of osteoporotic Kummell's disease.</p><p><b>METHODS</b>Total 16 patients with pathologically confirmed osteoporotic Kummell's diseases were reviewed from May 2010 to May 2012, including 4 males and 12 females with the mean age of 73.4 years (ranged, 67 to 83 years old). Radiologic imagings of all patients, including X-ray, CT and MRI, were analyzed retrospectively.</p><p><b>RESULTS</b>Intravertebral linear clefts could be seen on the AP and lateral X-ray films of vertebrae. Sagittal and axial CT scans demonstrated the vacuum cleft phenomenon with liquid and air was identified within the vertebral body. Sagittal MRI showed the callapsed vertebral segment and the area of fluid signal with clear and intact border within the vertebral body. The fluid signal was low on T1-weighted images and high on T2-weighted images and stir images, which was corresponding to an intravertebral vacuum cleft.</p><p><b>CONCLUSION</b>The radiologic characteristics of Kurmmell's diseases can provide valuable evidences for the early diagnosis.</p>

Analysis of treatment of osteoporotic intertrochanteric fracture of femur with the locking compression plate (LCP) / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the therapeutic effect and operating technique on the treatment of osteoporotic intertrochanteric fracture of femur with the locking compression plate (LCP).</p><p><b>METHODS</b>From Feb. 2006 to Oct. 2009, 49 patients with osteoporotic intertrochanteric fracture of femur were treaded with different internal fixation methods, concluded 22 males and 27 females with an average age of (74.68 +/- 5.94) years old ranging from 63 to 90 years. Among them, 29 patients were treaded with LCP, and the other 22 cases with DHS. According to X-ray and Ultrasound bone mineral desity, all cases were diagnosed in osteoporosis. The operative time, blood loss, fluoroscopy exposure frequency, bone healing time and the time of first away from bed.</p><p><b>RESULTS</b>All patients were followed up from 6 to 35 months. The operative time, fluoroscopy exposure frequency, the bone healing time and the time of being away from bed were compared between two groups, there were no statistical differences (t=1.347, 1.603, 1.973, 1.032, P>0.05). As compared with DHS group, the intraoperative blood loss in LCP group was less than that of DHS group, there were statistical differences (t=2.14, P<0.05).</p><p><b>CONCLUSION</b>The LCP is an effective method in the treatment of intertrochanteric fracture of femur. The method has the advantages such as small wound and early recovery, especially appropriate for older patients. But the procedure as well should be demanded strictly.</p>

Reduction and fixation of fracture of pubic rami by inserting construction plate through the punctiform-incision approach / 中国骨伤

<p><b>OBJECTIVE</b>To observe the effect of pubic fractures reducted and fixed thorough the punctiform incision approach.</p><p><b>METHODS</b>From 2002 to 2005, 10 cases with 18 fractures of pubis rami (8 male and 2 female) were treated with inserting construction plate by the punctiform incision approach. The average age of these patients was 37.2 years (range, 24 to 56 years). The mean duration between injury and operation was 8.7 days (range, 4 to 14 days).</p><p><b>RESULTS</b>Internal fixation for eighteen pubis fractures were accomplished by 28 punctiform incisions. The blood loss for each incision was averagely 30 ml, operation time of each pubic was about 45 minutes. Function restoration was evaluated by Majeed' score and all patients gained excellent result.</p><p><b>CONCLUSION</b>The fracture of pubic rami can be fixed sucessfully by punctiform incision approach. It provides smaller incision, less postoperative complications and excellent function rehabilitation.</p>
