Objective To compare the effectiveness of titanium elastic nail (TEN) and locking compression plate fixation in treating femoral subtrochanteric fracture in older children. Methods Between April 2015 and September 2016, 35 older children (aged 7-13 years) with femoral subtrochanteric fractures were treated, the clinical data were retrospectively reviewed. TEN fixation was used in 19 cases (group A) and locking compression plate fixation in 16 cases (group B). There was no significant difference in age, gender, sides, fracture causes, type of fracture, and time from injury to operation between 2 groups (P>0.05). The fluoroscopy times, operation time, intraoperative blood loss, fracture healing time were recorded and compared between 2 groups. The limb function was evaluated according to the Sanders scores and Flynnet al. outcome score. Results All the patients were followed up 6-24 months (mean, 11.46 months). The operation time, intraoperative blood loss, and fracture healing time of group A were significantly less than those of group B, but the fluoroscopy times of group A was significantly more than that of group B (P<0.05). All the fractures were healed, no breakage of screw, infection of deep tissue, nerve injury, osteonecrosis of the femoral head, or other complication occurred. At last follow-up, according to the Sanders scores, the results were excellent in 14 cases, good in 4 cases, and fair in 1 case in group A with an excellent and good rate of 94.74%; the results were excellent in 12 cases, good in 3 cases, and fair in 1 case in group B with an excellent and good rate of 93.75%; showing no significant difference between 2 groups (χ2=0.400, P=0.980). According to the Flynn et al. outcome score, the results were excellent in 13 cases, good in 5 cases, and fair in 1 case in group A with an excellent and good rate of 94.74%; the results were excellent in 11 cases, good in 3 cases, and fair in 2 cases in group B with an excellent and good rate of 87.50%; showing no significant difference between 2 groups (χ2=0.748, P=0.688). Conclusion Both TEN and locking compression plate have satisfactory outcomes for treating pediatric femoral subtrochanteric fractures. TEN method has minimally trauma, security, and faster fracture healing when compared with locking compression plate.
目的 比较外固定支架与锁定加压钢板（LCP）治疗桡骨远端die-punch骨折的疗效及适应证。 方法 2007年1月－2011年1月，分别采用外固定支架和LCP治疗桡骨远端die-punch骨折32例36侧，其中LCP固定19侧，外固定支架固定17侧。两组患者性别、年龄、致伤原因、骨折分类、伤后至入院时间等一般资料比较差异无统计学意义（P＞0.05）。术中对塌陷的关节面均采取撬拨植骨的方法恢复桡腕关节，克氏针固定较大骨折块。比较两种方法手术前后掌倾角、尺偏角、桡腕关节面恢复情况、骨折愈合时间，术后腕关节活动范围等。 结果 两组患者手术切口均Ⅰ期愈合，无感染发生。患者术后均获随访，随访时间6～24个月，平均13个月。所有患者骨折愈合良好，愈合时间、术后6个月X线片掌倾角、尺偏角两组间差异均无统计学意义（P＞0.05）；术后6个月腕关节尺偏活动度分别为（20.8 ± 3.6）°和（18.0 ± 2.8）°，LCP组优于外固定支架组（P＜0.05）；LCP组和外固定支架组桡骨高度分别为（10.9 ± 2.8）mm和（13.4 ± 2.3）mm，Gartland-Werley评分分别为（5.3 ± 2.4）分和（8.4 ± 3.6）分，两组差异有统计学意义（P＜0.05）。 结论 对于桡骨远端die-punch骨折，LCP可提供有效固定及早期活动，但对于关节面的塌陷及桡骨高度的恢复，外固定支架固定可提供良好的支撑作用。对于严重die-punch骨折可联合运用LCP和外固定支架等技术。
Objective To compare the effectiveness between locking compression plate (LCP) and locked intramedullary nail (IMN) for humeral shaft fractures of types B and C. Methods Between January 2010 and January 2012, 46 patients with humeral shaft fractures of types B and C were treated, and the clinical data were retrospectively analyzed. LCP was used for internal fixation in 22 cases (LCP group), and IMN in 24 cases (IMN group). There was no significant difference in gender, age, injury causes, the side of fracture, the site of fracture, the type of fracture, associated injury, and time from injury to operation between 2 groups (P gt; 0.05). The regular clinical examination and evaluation of radiography were done. Shoulder function was evaluated by Neer grading system and elbow function was evaluated by Mayo elbow performance score after operation. Results The operation time and intraoperative blood loss in IMN group were significantly lower than those in LCP group (P lt; 0.05). There was no significant difference in hospitalization time between 2 groups (t=0.344, P=0.733). All patients were followed up 16.8 months on average (range, 12-24 months). At 6 months after operation, bone nonunion occurred in 1 patient of LCP group and in 2 patients of IMN group; the bone healing rate was 95.5% (21/22) in LCP group and 91.7% (22/24) in IMN group, showing no significant difference (χ2=0.000, P=1.000). Except for nonunion patients, the bone healing time was (11.77 ± 0.75) weeks in LCP group and (11.38 ± 0.82) weeks in IMN group, showing no significant difference (t=1.705, P=0.095). Between LCP and IMN groups, significant differences were found in radial nerve injury (4 cases vs. 0 case) and impingement of shoulder (0 case vs. 6 cases) (P lt; 0.05), but no significant difference in superficial infection (1 case vs. 0 case) and iatrogenic fracture (1 case vs. 2 cases) (P gt; 0.05). There was no significant difference in shoulder function and elbow function at 1 year after operation between 2 groups (P gt; 0.05). Conclusion LCP fixation and IMN fixation for humeral shaft fractures of types B and C can achieved satisfactory results. More attention should be paid to avoiding radial nerve injury by fixation of LCP; nail tail should be buried deeply into the cortex of the greater tuberosity and rotator cuff should be protected to decrease the rate of impingement of shoulder by fixation of IMN.
Objective To evaluate the cl inical and radiological outcomes of minimally invasive plate osteosynthesis (MIPO) with locking compression plate (LCP) in the treatment of proximal humeral shaft fracture. Methods From July 2004 to April 2008, 26 patients with displaced fractures of the proximal humeral shaft were recruited, including 8 males and 18 females. Age of patients averaged 66 years old (range, 34-82 years old). According to AO classification, there were 4 cases of type A1, 2 cases of type A2, 8 cases of type B1, 4 cases of type B2, 2 cases of type B3, 4 cases of type C1 and 2 cases of type C2. The time from injury to surgery averaged 2 days (range, 1-5 days). There were 8 osteoporotic fractures. Results All surgical wound healed primarily, and there was no wound infection. Three patients had postoperative radial nerve neurapraxia, which recovered at 4, 6, 8 months respectively. All patients were followed up for 6-24 months with an average of 14.1 months. Radiological examination revealed bony union within 6 months in 25 cases. There was 1 delayed union which remained asymptomatic and eventually healed at 8 months with acceptable Constant-Murley score. There were 3 cases of shoulder impingement syndrome diagnosed at 3 months post-operatively. After implant removal, they all achieved an acceptable Constant-Murley score. According to Constant-Murley scoring system, there were 11 excellent, 10 good and 5 acceptable results. The excellent or good rate was 80.8%. Conclusion MIPO technique using LCP is an effective method to treat proximal humeral shaft fractures, which facil itates functional recovery of the shoulder joint. During the surgery, it is important to achieve a good fracture reduction and to avoid compl ications.
Objective To review the outcomes of geriatric distal humeral fracture fixed with locking compression plate (LCP). Methods From January 2005 to December 2007, 24 patients (20 females and 4 males) with distal humeral fracture underwent open reduction and internal fixation with LCP. Their average age was 75.5 years old, ranged from 60 to 93 years old. Fracture was caused by injury from fall in 22 cases, by traffic accident in 1 case, and by direct hit in 1 case. There were 12 cases of type A2, 2 cases of type A3, 2 cases of type B1, 2 cases of type C1, 2 cases of type C2, 4 cases of type C3 fractures according to AO/ASIF classification. X-ray films in AP and lateral view were taken preoperatively. CT scan with three dimensional reconstructions was done in more comminuted fracture only. Open reduction with triceps sparingtechnique was used in all except type B fracture, and olecranon osteotomy was considered only in more comminuted C3fracture. The average interval between injury and operation was 3 days (range, 1-6 days). Outcome measures includedpain assessment, range of motion, and Mayo elbow performance score and findings at 1 year follow-up. Results Theaverage length of follow-up was 25 months (range, 12-48 months). All 24 fractures were healed within 6 months with anaverage of about 4 months. At 1 year follow-up, 83% (n=20) of patients felt no pain and 17% (n=4) of patients had mildpain; 83% of patient can gain a flexion range of more than 100°; according to Mayo elbow performance score, the meanscores of type A, B and C fracture groups were 97, 85, and 89, respectively, and the post-operative performance of typeA fracture was significantly better than that of type B and C (P=0.034). Four patients had postoperative compl ications.Conclusion Open reduction and internal fixation of geriatric distal humeral fracture can achieve relatively good functionalresult and bony union despite of age.
