Objective To investigate the operative procedure and the therapeutic effects of unstable femoral intertrochanteric fracture in elderly patients with rebuild septum bronchiale in artificial femoral head replacement. Methods From October 2005 to October 2007, 113 elderly patients with unstable femoral intertrochanteric fracture were treated with artificial femoral head replacement with fixation of femoral greater trochanter and smaller trochanter in the help of bone cement in 58 cases (test group) and with γ-type bone nail in 55 cases (control group). In test group, there were 21 males and 37 females with an average age of 75 years, including 10 cases of type IIIA, 16 cases of type IIIB and 32 cases of type IV according to Evans-Jenson standard. In control group, there were 17 males and 38 females with an average age of 72.5 years,including 13 cases of type IIIA, 14 cases of type IIIB and 28 cases of type IV according to Evans-Jenson standard. All fractures were caused by fall damage. The disease course was 3 hours to 7.5 days (mean 1.4 days). The patients of two group compl icated with osteoporosis, and compl icated by one or several compl ications of coronary heart disease, hypertension, diabetes and chronic bronchitis. And all patients did not had fracture at other sites. There was no significant difference in general data between two groups (P gt; 0.05). Results The operations were successful, the incision healed by first intention. There were significant differences in operation time, operative blood loss and blood-transfusion between two groups (P lt; 0.05). The two group were followed 12-36 months. There were significant differences (P lt; 0.05) in the incidence rate of compl ication and the excellent and good rate of hip function (by Harris standard) between the test group (3.4% and 93.1%) and the control group (16.4% and 70.9%) 12 months after operation. Conclusion The aged patients with intertrochanteric fracture can get good result through caput femoris replacement, and rebuild septum bronchiale is of great significance.
Objective To explore the factors to affect severity of hyperextension injury of the cervical spinal cord (HEICSC). Methods Forty-five patients with HEICSC, 35 males and 10 females, aged 27-67 years old (mean 48.2 years old), were retrospectively analyzed. The disease course was 30 minutes to 16 days. According to modified Frankel grading, there were 6 cases of grade A, 8 cases of grade B, 16 cases of grade C and 15 cases of grade D. Spinal cord injuries (SCI) segments were determined according to SCI plane and high signal change (HSC) in spinal cord on MR images. The whole or large part of HSC segments were supposed to be main injured spinal cord segments (MISCSs) and the staccato or patchy HSC ones were supposed to be common injured spinal cord segments (CISCSs). When the external force acting on head or face suffered was larger, the force produced during high-speed movement or forehead and/or face had severe contused and/or) lacerated wound, the force was defined severe traumatic strength, whereas the reverse was true for sl ight traumatic strength. According to signal magnitude of the cervical discs on T2-weighted MR images, degeneration of cervical discs and cervical vertebras were classified into 5 grades: grade 0-4. Cervical spinal stenosis were graded to 5 grades according to the width of anterior or posterior cerebrospinal fluid layer to spinal cord on T2-weighted MR images and compressed degree of spinal cord on T1-weighted MR images. The influence of traumatic strength, cervical spinal degeneration or cervical spinal stenosis on SCI were explored. Results Among the 45 cases, 12 cases were caused by sl ight traumatic strength, 33 cases were caused by severe one. The cervical spinal cord was injuried more sl ightly and the patients were older in the sl ight traumatic strength cases than in the severe ones (P lt; 0.05). The number of MISCSs were 45 in 40 cases and the 25 segments were located at C3, 4 level. The number of CISCSs were 39 in 21 cases. All the cervical vertebraes of the 45 patients had degenerated. The most were in grade 3 in 22 patients and the severest degenerative segments were mostly located in C5,6 discs in 35 ones. The number of the MISCSs in different degenerative grades of discs was 0 in grade 0, 9 in grade 1, 20 in grade 2, 14 in grade 3, and 2 in grade 4. The ratios of the segment number of injuried spinal cord to the segment number of spinal stenosis in every grade of stenosis were 1/62 in grade 0, 2/11 in grade 1, 27/52 in grade 2, 33/33 in grade 3, 21/22 in grade 4. Conclusion Three main factors including the magnitude of traumatic strength, the degree of instabil ity of cervical vertebrae and the degree of cervical stenosis contribute to development and progress of HEICSC.
