Damage control orthopaedics of thoracolumbar burst fracture complicated with severe polytrauma / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the therapeautic effect of damage control orthopaedics (DCO) applicated to thoracolumbar burst fracture complicated with severe polytrauma.</p><p><b>METHODS</b>Twenty-one patients with severe polytrama including 15 males and 6 females with an average age of 40-years-old ranging from 20 to 60 years, were treated by immediate fluid resuscitation and emergency simple operation so as to control the bleeding and contamination. According to Frankel grade of spinal nerves function, 3 cases were grade A, 3 were grade B, 9 were grade C, 6 were grade D. Ten cases were performed to open abdominal operation, 6 cases underwent closed negative pressure drainage thorough chest, 2 cases with lung rupture were treated by repairing operation. During operation, 9 cases were treated with by external fixation and 5 cases were skeletal traction or external fixation with plaster support for extremities fractures. After emergency operation, the patients were transported into surgical intensive care unit (SICU), and corrected the hypothermia, acidosis and coagulation. The definitive thoracolumbar operation was performed between 5 to 7 days as soon as the vital signs became stable.</p><p><b>RESULTS</b>Among 21 cases, trauma hemorrhagic shock was corrected rapidly in 18 cases and 3 cases died in 4 to 26 hours. The survival rate was about 85.7% (18/21). Eighteen patients were followed up for 6 to 14 months with an average of 10 months. According to Frankel grading, 3 cases were grade A, 2 cases were grade B, 3 cases were grade C, 3 cases were grade D, 7 cases were grade E.</p><p><b>CONCLUSION</b>It may increase the therapy achievement rate excellently and decrease the disabled rate that performing damage control orthopaedics (DCO) timely, relifing the compression on the spinal cord and re-establishing the stability of spinal column as early as possible.</p>

Locking compressing plate combined with bone-grafting in medullary cavity for treatment of the distal fractures of tibia at delayed stage / 中国骨伤

<p><b>OBJECTIVE</b>To explore the clinical effects of delayed open reduction and locking compressing plate (LCP) plus bone-grafting in medullary cavity for the distal comminuted fractures of tibia.</p><p><b>METHODS</b>Twenty-nine patients with the distal comminuted fractures of tibia were treated between March 2006 and September 2008, including 19 males and 10 females, ranging in age from 27 to 58 years with an average of 42.5 years. From wounded to hospital, the time was from 2 to 4 hours. According to AO classification, type 43-A1 were in 3 cases, type A5 in 12 cases, type A3 in 9 cases and type 43-C1 in 5 cases. Among them, there were 11 cases with open fracture (type Gustilo I in 5 cases, type Gustilo II in 6 cases) and 18 cases with closed fracture. Calcaneal traction was done in earlier stage (plaster external fixation in 5 cases), keeping the nagative liquid balance and electrolyte balance and improving the microcirculation. After the swolen limbs relieved markedly in 8 to 12 days,operating was done by open reduction and LCP internal fixation plus bone-grafting with own ilium in medullary cavity. Functional exercise was undergone in earlier stage and the wounded limbs loading weight on 10 to12 weeks after operation when the X-ray revealed the callus formed markedly.</p><p><b>RESULTS</b>The incision healed well without severe complication. All patients were followed up for from 6 to 14 months with an average of 12 months. All cases obtained bone union. According to the Mazur's evaluation standard, the results were excellent in 25 cases, good in 3 cases, and fair in 1 case.</p><p><b>CONCLUSION</b>The above treatment can reduce the damage of periosteum and medullary cavity, shorten the time of bone healing and decrease the rate of bone nounion markedly. The internal fixation was reliable and less complacation after surgery, but it is very important for the right preoperation assessment to soft tissue injuries and the good operation timing choice.</p>
