Surgical treatment for posterior Pilon fracture through posterolateral approach / 中国骨伤

<p><b>OBJECTIVE</b>To explore clinical results of open reduction and internal fixation (ORIF) for posterior Pilon fracture through posterolateral approach.</p><p><b>METHODS</b>Seventeen patients with posterior Pilon fracture were treated through posterolateral approach from February 2010 to April 2013. Among them,including 11 males and 6 females aged from 29 to 59 with an average of 43.4 years old. All fractures were associated with more than 20% of articular surface of distal tibial. The causes of injury included falling down (11 cases), traffic accident (4 cases) and sports injury(6 cases). Fracture classification was based on posterior pilon fracture by YU Guang-rong, including type I (6 cases), type II (2 cases) and type III (6 cases). Fracture healing time, fracture reduction and postoperative complications were observed, AOFAS score were applied to evaluate clinical efficacy.</p><p><b>RESULTS</b>All patients were followed up from 13 to 24 months with an average of 20.5 months. All incisions were healed at stage I, and fractures obtained healing,the time of fracture healing ranged from 12 to 21 weeks with an average of 15.2 weeks. No incision infection, neurovascular injury, bone ununion and fracture deformity were found after operation. Postoperative AOFAS score was 92.0 ± 10.2, and 14 cases got excellent results, 2 good and 1 moderate.</p><p><b>CONCLUSION</b>Posterior pilon fracture through posterolateral approach could obtain effective reduction, stable fixation. It is a safe, simple and effective operation for treating posterior Pilon fracture, and it is worth popularizing.</p>

Treatment of thoracolumbar spinal tuberculosis with single posterior debridement, bone grafting, internal fixation and local chemotherapy / 中国骨伤

<p><b>OBJECTIVE</b>To evaluate the clinical effects of single posterior debridement, bone grafting, internal fixation and local chemotherapy in treating thoracolumbar spinal tuberculosis.</p><p><b>METHODS</b>From February 2009 to September 2012,11 patients with thoracolumbar spinal tuberculosis were treated by single posterior debridement, bone grafting, internal fixation and local chemotherapy. There were 7 males and 4 females, aged from 27 to 65 years old with an average of 53.7 years. The courses of disease was from 3 months to 2 years with the mean of 9 months. According to ASIA standard of spinal cord injury, 3 cases were grade C and 8 cases D. After treatment, clinical effects were evaluated by ASIA grade, visual analogue score (VAS) and Oswestry Disability Index (ODI); kyphosis Cobb angle change was observed by X-rays.</p><p><b>RESULTS</b>Eleven patients were followed up from 12 to 29 months with an average of 18 months. ASIA grade of spinal cord injury, 3 patients with grade C improved to grade D in 2 cases and grade E in 1 case 8 patients with grade D improved to grade E in 7 cases and unchanged in 1 case. VAS decreased from preoperative 6.10 ± 1.30 to 1.70 ± 0.80 at 3 d after operation (P < 0.05). ODI improved from preoperative (68.36 ± 10.41)% to (14.55 ± 8.99)% (P < 0.05) at 3 d after operation. Kyphotic Cobb angle was corrected from preoperative (22.64 ± 4.84)° to (4.27 ± 1.49)° (P < 0.05) on the 3rd day after operation, and angle loss was mild at final follow-up, there was no significant difference between postoperative at 3 d and final follow-up.</p><p><b>CONCLUSION</b>Single posterior debridement, bone grafting, internal fixation and local chemotherapy for the treatment of thoracolumbar spinal tuberculosis can effectively remove the lesion, improve nerve function and correct deformity, has advantage of single incision, little trauma, and low recurrence rate. But it still need long-term and systemic treatment with anti-TB drugs.</p>

AO elastic intramedullary nailing for the treatment of clavicle fractures / 中国骨伤

<p><b>OBJECTIVE</b>To evaluate the outcome of Titanium elastic intramedullary nailing (TEN) for the treatment of displaced midclavicular fractures.</p><p><b>METHODS</b>Between February 2010 and February 2013, 62 patients with displaced midclavicular fractures were treated by TEN, including 27 males and 35 females with an average age of 37.6 years old ranging from 15 to 67 years. The course of disease was from 1 to 9 days (means 2.7 days). Thirty-nine cases were treated by closed reduction and 23 cases by assistant small incision. Based on OTA (the Orthopaedic Trauma Association classification) classification, 31 cases of simple fractures involved 5 cases of 06-A1,15 cases of 06-A2,11 cases of 06-A3; 31 cases of wedge fractures involved 4 cases of 06-B1,12 cases of 06-B2,15 cases of 06-B3. Postoperative pain relief were evaluated by VAS score,and operation time,fracture healing time were recorded. After 6 weeks and after removing internal fixation shoulder joint function was evaluated by Constant score, and shoulder joint function were assessed by Herscovici score after 6 weeks.</p><p><b>RESULTS</b>Except 2 cases were lost to follow-up, 2 cases did not remove internal fixation, 3 cases' fractures were nonunion, the remaining 55 patients received follow-up for an average time of 11.4 months. The average preoperative VAS score was 5.20±0.71, and it turned to be 1.550.59 at 3 days after operation. The average operative duration was 40 min (15 to 65 min). The average bone healing time was (2.71±0.54) months (2 to 5 months). No difference about bone healing time was found between simple fractures and wedge fractures,and between the patients treated by closed reduction and assistant small incision. According to Herscovici standard, the shoulder function was excellent in 49 cases, good in 4, fair in 1, and poor in 1. Simple fractures achieved better Constant score than wedge fractures at 6 weeks postoperatively, whereas no difference was found at 4 weeks after fixation removal.</p><p><b>CONCLUSION</b>Titanium elastic nails (TEN) for treatment of displaced midclavicular fractures has advantages of good clinical effect,rapid pain relief,fast recovery of shoulder joint function. For OTA classification type B patients with comminuted fracture can replace steel to achieve very good effect, but to grasp the appropriate.</p>
