Bridging fixation with locking plate for the treatment of subtrochanteric femoral fractures of Seinsheimer type V / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the clinical effect of bridging fixation with locking plate for the Seinsheimer type V subtrochanteric femoral fracture.</p><p><b>METHODS</b>From March 2009 to September 2014,18 cases of Seinsheimer type V subtrochanteric femoral fracture were treated by open reduction and bridging fixation with locking plate through proximal and distal approach including 16 males and 2 females with an average age of 41 years old ranging from 22 to 67 years old. Among them, 12 cases caused by traffic accident, 5 cases by falling, 1 case by heavy aboving. All cases were fresh and closed fractures. Time between injury and operation was from 4 to 9 days with an average of 6.2 days. Of them, 11 cases were fixed with reverse LISS and the other 7 cases were fixed with anatomical locking plates of proximal femur.</p><p><b>RESULTS</b>The mean time of operation was 110 min (ranged from 90 to 155 min). The mean blood loss during operation was 425 ml (ranged from 350 to 650 ml) and 16 cases got blood transfusion which was meanly 300 ml. The mean hospital time was 14 days (ranged from 12 to 18 days). The mean duration of followed up was 11.8 months (ranged from 8 to 22 months). The mean time of bone union was 6.6 months (ranged from 5 to 8 months). There was not any complication such as infection, implant failure, hip varus, external rotation deformity of low limb or fat embolism. The Sanders hip scores were 53.22 ± 6.48, the result was excellent in 12 cases and good in 6 cases at the last follow-up.</p><p><b>CONCLUSION</b>Under the principle of biological osteosynthesis, treatment of Seinsheimer type V subtrochanteric femoral fracture with bridging locking plate fixation has such advantages as high mechanism, less interference of blood supply, stable fixation and little complication. It is a safe and idea way for the treatment of the Seinsheimer type V subtrochanteric femoral fracture.</p>

Case-control study on close reduction combined with minimally invasive percutaneous plate osteosynthesis for the treatment of distal fracture of tibial shaft / 中国骨伤

<p><b>OBJECTIVE</b>To compare the effects of close reduction combined with minimally invasive percutaneous plate osteosynthesis for distal fracture of tibial shaft.</p><p><b>METHODS</b>From March 2009 to May 2013, there were 124 patients (89 males and 35 females, 30 of them were injured in a traffic accident and 94 were falling down in daily life, the ages ranging from 21 to 81 years old) who suffered from distal fracture of tibial shaft. Sixty-six patients (48 males and 18 females, 45 cases of type A, 12 cases of type B and 9 cases of type C) were treated with close manipulative reduction combined with minimally invasive percutaneous plate fixation. After close reduction, a minimal incision was made and a anatomic plate was inserted just along the medial tibia periostea, and then the fracture was fixed without fracture exposure. The other 58 patients (41 males and 17 females, 41 cases of type A, 10 cases of type B and 7 cases of type C) were treated with conventional open reduction and internal fixation. Length of the incision, operating time, early postoperative pain (recorded using the Visual Analog Scale score) and the outcome results (recorded using the evaluation standard of Johner-Wruhs) were compared.</p><p><b>RESULTS</b>The length of incision was meanly (7.34 ± 1.42) cm in MIPPO group and (21.82 ± 2.35) cm in ORIF group; operation time was (44.48 ± 10.00) min in MIPPO group and (59.42 ± 11.84) min in ORIF group. The postoperative radiographs verified good position of all screws and satisfactory bone fracture reduction in both groups. All the patients were followed up, and the duration ranged from 10 to 24 months (mean 15.2 months) in both groups. In MIPPO group,only one patient had delayed union and got union after Chinese herb therapy. The other 65 patients got bony union during 15 to 20 weeks. While in ORIF group, 3 patients suffered from nonunion and received reoperation with bone grafting, and 4 patients got bone infection.</p><p><b>CONCLUSION</b>Treatment of distal fracture of tibial shaft, combined with close reduction and MIPPO technique, has the advantages such as less invasion, less damage of blood supply, simplified procedure of operation and higher union rate, which is an ideal methods and is accordant to the biological demand.</p>

Case-control study on close manipulative reduction combined with minimally invasive percutaneous plate fixation for the treatment of proximal humeral fractures / 中国骨伤

<p><b>OBJECTIVE</b>To compare the clinical effects of close manipulative reduction combined with minimally invasive percutaneous plate fixation(MIPPO) and conventional open reduction and internal fixation (ORIF) for the treatment of proximal humerus fractures.</p><p><b>METHODS</b>From April 2008 to March 2013, among the 75 patients with fractures of proximal humerus, 26 patients were male and 49 patients were female, ranging in age from 22 to 80 years; 18 patients had injuries caused by traffic accident and 57 patients had injuries caused by falling down. According to Neer classification, there were 49 cases of two-part fractures and 26 cases of three-part fractures. All the patients were divided into two groups: MIPPO group and ORIF group. There were 12 males and 21 females in the MIPPO group,including 22 cases of Neer two parts and 11 cases of Neer three parts, who were treated with close manipulative reduction combined with MIPPO. While the other 42 patients were in the ORIF group,including 16 males and 26 females. Among those patients,27 cases belonged to Neer two parts and 15 cases of Neer three parts, who were treated with ORIF. Length of the incision, blood loss, operating time, early postoperative pain(recorded by VAS), neck-shaft angle of proximal humerus and postoperative function of shoulder(recorded by Constant-Murley score, including pain, function, ROM and muscle length) were compared.</p><p><b>RESULTS</b>The mean lengths of incision were (6.74 +/- 0.38) cm in MIPPO group and (16.82 +/- 1.74) cm in ORIF group;blood losses were (110.15 +/- 29.49) ml in MIPPO group and (326.19 +/- 59.71) ml in ORIF group; operation times were (48.60 +/- 10.18) min in MIPPO group and (68.84-16.22) min in ORIF group. VAS of patients in MIPPO group on the 1st and 3rd days postoperatively were lower than those of patients in the ORIF group. The postoperative radiographs verified good position of all screws and satisfactory reduction of bone fracture reduction in both groups. All the patients were followed up,and the durig ranged from 8 to 24 months (mean 14.2 months). In the MIPPO group, there was no humeral head necrosis and all patients gained bone union; while in the ORIF group, 3 patients sustained nonunion and received reoperation for bone grafting, and 2 patients sustained humeral head necrosis. The mean Constant-Murley scores of shoulder were 88.94 +/- 2.57 in the MIPPO group and 86.00 +/- 3.36 in the ORIF group.</p><p><b>CONCLUSION</b>The close manipulative reduction combined with MIPPO is a better choice for fixation of proximal humerus fractures, compared with conventional plate. This method possesses such advantages as a shorter incision, less disturbance of the blood supply and stable fixation of the fracture, allowing early exercise so that the function of shoulder recovers rapidly.</p>

<p><b>OBJECTIVE</b>To evaluate the clinical effects of close reduction combined with minimally invasive percutanous plate osteosynthesis (MIPPO) for proximal and distal tibial fractures.</p><p><b>METHODS</b>From March 2007 to December 2010, 56 patients with proximal and distal tibial fractures were treated with close reduction combined with MIPPO technique. There were 39 males and 17 females,aged from 22 to 67 years with an average of 41.3 years. Left fracture was in 25 cases and right fracture was in 31 cases; proximal tibial fracture was in 15 cases and distal tibial fractures was in 41 cases; 34 cases caused by fall down and 22 cases caused by road accident. The mean time from injury to operation was 1.7 d. Clinical manifestation included pain, swelling of leg with limitation of activity. According to the standard of Johner-Wruhs, clinical effects were evaluated.</p><p><b>RESULTS</b>The mean operative time was 46 min in 56 patients. All fractures obtained satisfactory reduction and the location of plate was good. Incisions healed with one-stage and no superficial or deep infection was found. All the patients were followed up from 8 to 23 months with an average of 14.2 months. Only one fracture complication with delayed union,and after auto grafting with ilium bone,the fracture got union. Other 55 cases obtained bone healing in 15 to 20 weeks after operation and no internal fixation failure was found. The time of walking was 4-6 months after operation,without limping at 7 months after operation. Both lower extremities were symmetrical and the function of knee and ankle got complete recovery. According to the criteria of Johner-Wruhs score,46 cases obtained excellent results,9 good and 2 fair.</p><p><b>CONCLUSION</b>Treatment of proximal and distal tibial fractures with close reduction and MIPPO technique can not only preserve soft tissue,simplify operative procedure and decrease wound, but also can obtain rigid internal fixation and guarantee early function exercises of knee and ankle joints. The method has the advantages of less soft tissue injury, less blood loss, reliable fixation, which is effective method in treating proximal and distal tibial fractures and corresponds with the standpoint of biological fixation.</p>
