Comparison of long Gamma 3 nail and proximal femur locking plate for the treatment of femoral subtrochanteric fractures / 中国骨伤

OBJECTIVE@#To compare clinical efficacy of long Gamma 3 nail and proximal femur locking plate (PFLP) in treating femoral subtrochanteric fractures.@*METHODS@#From January 2010 to January 2017, clinical data of 58 patients with subtrochanteric fractures followed more than 12 months were retrospective analyzed. Among them, 35 patients were treated with long Gamma 3 nail including 18 males and 17 females aged from 25 to 78 years old with an average of(66.5±23.5) years old;Causes of injury included fall on the ground in 18 cases, traffic accidents in 7 cases, and fall from height in 10 cases. The other 23 patients were treated with PFLP fixation including 8 males and 15 females aged from 31 to 81 years old with an average of (63.4±22.4) years old;Causes of injury included fall on the ground in 12 cases, traffic accidents in 6 cases, and fall from height in 5 cases. Operative time, blood loss (intraoperative and hidden blood loss), hospital stays, bone healing and complications were observed and compared. Harris hip score after 1-year following-up was used to evaluate postoperative clinical effect.@*RESULTS@#Fifty-one patients were followed up from 14 to 36 months with an average of 24.8 months, including 31 patients were treated with long Gamma 3 and 20 patients were treated with PFLP. Blood loss(intraoperative and hidden blood loss) in PFLP group was less than that of long Gamma 3 nail group(0.05). There was no significant differences in healing time of fractures between long Gamma 3 nail group (17.2±2.4) weeks and PFLP group (18.1±2.6) weeks(<0.05). At 1-year following-up, there was no significant differences in Harris hip score between long Gamma 3 nail group(80.29±10.28) and PFLP group (76.49±12.28)(<0.05). No complications such as pulmonary embolism and nonunion occurred. Two patients were treated with fitler whose occurred deep vein thrombosis. Postoperative pulmonary infection curred in 4 cases and was cured by anti-infection therapy.@*CONCLUSIONS@#Both of long Gamma 3 nail and PFLP in treating patients with femoral subtrochanteric fractures can receive good clinical effects, long Gamma 3 nail is not suitable for the patients of the narrow medullary cavity and prominent anterior arch. PFLP is eccentric fixation, so early weight-bearing was not stress.

Advanced progress on the treatment of anterior approach to the thoracolumbar vertebral fractures / 中国骨伤

Thoracolumbar fractures are common and severe traumas. Anterior approaches can achieve adirect spinal cord decompression and reconstruct anterior column height what load bearing the major load distribution of the spine. Therefore, anterior approach is an important method in the treatment of thoracolumbar fractures. With the application of pedicle screw, most of the patients were treated with posterior approaches.Because of the unique advantages of anterior approach, the posterior approach can not be replaced it.The review summarizes the biomechanical characteristics? indications? fixation devices? bone grafting method and technique of the anterior approach and in order to provide better evidence for clinical treatment of thoracolumbar fractures.

Inversive LISS plate in treating intertrochanteric and subtrochanteric fractures combined with femoral shaft fractures / 中国骨伤

<p><b>OBJECTIVE</b>To study clinical effects of inversive LISS(less invasive stabilization system, LISS) plate for the treatment of intertrochanteric and subtrochanteric fractures combined with femoral shaft fractures.</p><p><b>METHODS</b>From January 2012 to January 2015, 24 patients with intertrochanteric and subtrochanteric fractures combined with femoral shaft fractures were treated with inversive LISS plate, included 16 males and 8 females with an average age of 62.5 years old ranged from 35 to 81 years old. There were 8 cases of traffic accident injuries, 3 cases of falling from high place, and 13 cases of falls injuries. The time from injury to operation was ranged from 2 to 12 days with an average of 5.2 days. The operation time, intraoperative blood loss and the length of hospitalization were analyzed. The fracture union was assessed by follow-up radiographs and hip functional recovery by Harris hip scoring.</p><p><b>RESULTS</b>All patients were followed up for 16.2 months (ranged, 18 to 36 months). The mean operative time was (68.22±48.36) min;the mean blood loss was (256.28±182.46) ml;the mean time of hospitalization was(14.8±5.2) days. There were no complications such as deep infection, deep vein thrombosis, pulmonary embolism and bone nonunion during the follow up period. The bone healing was ranged from 3 to 8 months with an average of 4.8 months. The mean Harris score was 76.49±12.28 at the final follow-up, 15 cases were classified as excellent, 6 as good and 3 as fair.</p><p><b>CONCLUSIONS</b>Inversive LISS plate can be used in treating with intertrochanteric and subtrochanteric fractures combined with femoral shaft fractures, and should not emphasis on premature loading.</p>

Awn needle therapy on the impact of urinary retention after spinal cord injury / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the therapeutic mechanism of point 8L54-through-point ST2S acupuncture with elongate needles in treating urinary retention after spinal cord injury.</p><p><b>METHODS</b>Thirty-five healthy Japanese rabbits (weight 2.5 +/- 0.25 kg, 3 months old, male or female), used as experimental subjects, were divided into 4 groups involving blank group, model group, acupuncture group, elongate needles group (5 rabbits in blank group, 10 rabbits in each of the other group 10). Modified Allen's method was used to cause spinal cord injury model for the model group, the acupuncture group and the elongate needles group, the blank group was only sham surgery. Immediately after spinal cord injury model,the elongated needle group was given the bilateral acupoints of the elongated needle penetration needling and electric stimulation, electrical stimulation 15 mm stimulation frequency of 20 to 40 times/mm, intensity 1.5 to 3 V the acupuncture group immediately was given ordinary electric needle acupuncture, given other disposals as the elongated needle group; model group was not given electric needle acupuncture, waiting 15 minutes, started to detect and record the observed indicator as the elongated needle group; the blank group was only sham surgery. The following indicators including the Tarlov score ,urinary bladder pressure point, the threshold urination, voided volume, were observed in the first day and the fifth day after surgery.</p><p><b>RESULTS</b>Three groups of animals which modeled were urinary retention after operation. Compared to 1 d, Tarlov score of model group, acupuncture group and elongate needles group significantly improved at postoperative 5 d (P < 0.05). Compared with acupuncture group, the Tarlov score of elongate needles group had no significant difference at postoperative 5 d (P > 0.05). Compared with model group, values of urinary bladder pressure point decreased with varying degrees in the acupuncture group and elongate needles group at postoperative 5 d (P < 0.05); relative to the acupuncture group, the point of the bladder voiding pressure in the elongate needles group decreased more significantly at postoperative 5 d (P < 0.05); compared with model group, micturition threshold of acupuncture group and elongate needles group had been significantly improved at the fifth day after surgery (P < 0.05); relative to the acupuncture group, the improvement is more obvious in the elongate needles group. Compared with model group, voided volume of acupuncture group and elongate needles group had increased significantly at the fifth day after surgery (P < 0.05); relative to the acupuncture group, the increment is more evident in the elongate needles group (P < 0.05).</p><p><b>CONCLUSION</b>To treat urinary retention after spinal cord injury, the method, which was point-through-point acupuncture with elongate needles in the "Zhibian" and "Shuidao", was better than general acupuncture method. The therapeutic mechanism may be related to stimulate peripheral nerve of bladder, and to rectify the dysfunction between detrusor and sphincter.</p>

Seasonal distribution of active systemic lupus erythematosus and its correlation with meteorological factors

OBJECTIVE: To explore the characteristics of seasonal distribution of active systemic lupus erythematosus (SLE) and the influences of meteorological factors including temperature and humidity on active systemic lupus erythematosus. METHODS: The characteristics of seasonal distribution of active SLE and its correlation with meteorological factors were retrospectively analyzed in 640 patients living in the city of Zhanjiang, China and had active SLE between January 1997 and December 2006. RESULTS: In winter, when there are weaker ultraviolet (UV) rays, the ratio of patients with active SLE to total inpatients was 3.89 percento, which is significantly higher than in other seasons with stronger UV rays, including 2.17 percento in spring, 1.87 0 in summer and 2.12 0 in autumn. The number of patients with active SLE had significant negative correlation with mean temperature and was not significantly related to mean humidity. CONCLUSION: Active SLE has the characteristics of seasonal distribution and is associated with temperature. The mechanism remains to be further studied.
