RESUMO

<p><b>OBJECTIVE</b>To investigate relation between displaced inferior ramus fractures and posterior pelvic ring injury.</p><p><b>METHODS</b>From August 2012 to August 2015, 51 patients of pubic ramus fractures with complete record were retrospective reviewed including 27 males and 24 females with an average age of(49.1±19.0) years old ranging from 9 to 90 years old. The time from injury to treatment ranged from 0.3 to 48 hours with an average of 10.1 hours. According to Tile classification of pelvic fractures, 28 cases were type A, 17 cases were type B, 6 cases were type C. Pelvic radiographs and computed tomography scans were detailed and evaluated for whether there were posterior pelvic ring injury, meanwhile pubic rami fractures were divided into 4 groups as follow: displaced inferior ramus fractures group, undisplaced inferior ramus fractures group, displaced superior ramus fractures group, undisplaced superior ramus fractures group;the incidence rate of association of posterior pelvic ring injury was determined and compared.</p><p><b>RESULTS</b>Twenty-six patients had displaced inferior ramus fractures, all of them (100%) were combined with posterior pelvic ring injury. Twenty patients had undisplaced inferior ramus fractures, 6 of them(30%)were combined with posterior pelvic ring injury. Twenty-eight patients had displaced superior ramus fractures, 22 of them(78.5%) were combined with posterior pelvic ring injury. Twelve patients had displaced superior ramus fractures, 5 of them(41.6%) were combined with posterior pelvic ring injury. Compared with undisplaced inferior ramus fractures group, there was statistic difference(=0.028 8<0.05) on the incidence rate of posterior pelvic ring injury, there were no statistic difference(=0.055 8>0.05;=0.168 3>0.05) while compared with other undisplaced superior ramus fractures group and displaced superior ramus fractures group, but the incidence rate of association with posterior pelvic ring injury much higher than both of two groups (100% vs 41.6%, 78.5%).</p><p><b>CONCLUSIONS</b>Displaced inferior pubic ramus fractures have the highest incidence rate of association with posterior pelvic ring injury, frequently prompted injury to the posterior pelvis. Displaced inferior ramus fractures were an indirect evidence of posterior pelvic injury.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate the relationship between degree of abnormal deeper lateral femoral notch between anterior cruciate ligament tear.</p><p><b>METHODS</b>The radiograph and MRI image material of 16 patients with anterior cruciate ligament injury from January 2013 to November 2013 were reviewed including 14 males and 2 females with an average age of 28.3 years old ranging from 18 to 52 years. Eleven cases was on right side and 5 on left. Survey tool of PASC imaging system was used to measure the depth of lateral femoral notch in patients with abnormal indicated by lateral X-ray view or sagittal view of MRI in knee joint,while clinical data,physical examination,image material in arthroscopy of these patients were retrospective researched.</p><p><b>RESULTS</b>Four patients had an abnormal lateral femoral notch with the depth of 2 mm on lateral X-ray and sagittal MRI, while positive anterior drawer sign and Lachman test as well as anterior cruciate ligament tears on MRI, and completed tears were comfirmed on the operation of arthroscopy. Two patients without abnomal lateral femoral notch on lateral view of X-ray while with the depth of 1 mm on sagittal view of MRI were also coupled with positive anterior drawer sign and Lachman test as well as anterior cruciate ligament tears on MRI, and one of them were comfirmed completed anterior cruciate ligament tears on the arthroscopy operation and completed tear could not comfirmed on another one because of disagreed with arthroscopy operation.</p><p><b>CONCLUSION</b>There appears to be an association between abnormal lateral femoral notch on lateral view of knee with anterior cruciate ligament tears. An abnormal deeper lateral femoral notch is an indirect evidence for anterior cruciate ligament tears.</p>
