Objective To determine the efficacy and safety of external fixation versus intramedulllary nailing in the treatment of adult tibial shaft fracture. Methods We searched the specialized trials register of The Cochrane Collaboration’s Bone, Joint and Muscule Trauma Group, The Cochrane Library (CENTRAL), MEDLINE (1966 to March 2006), EMBASE (1980 to March 2006) and PUBMED (1966 to March 2006). We also handsearched some Chinese orthopedic journals. Randomized controlled trials (RCTs) and quasi-randomized trials (quasi-RCTs) comparing external fixation versus intramedullary nailing for tibial shaft fractures in adults were included. The quality of these trials was critically assessed. We used the Cochrane Collaboration’s RevMan 4.2.8 for data analyses. Result Three RCTs and two quasi-RCTs involving a total of 279 patients were included. The results of meta-analyses showed that external fixation for tibial shaft fractures in adults may increase the infection rate [RR 2.45, 95%CI (1.31,4.61), P=0.005], and the malunion rate [RR 2.85, 95%CI (1.20,6.79), P=0.02] but may reduce the duration of hospitalization [RR –5.50, 95%CI (–6.99,–4.01)]. The nonunion rate, delayed healing rate, and healing time, were comparable between external fixation and intramedulllary nailing. Conclusion The trials available for this systematic review are too few and small for reliable estimates of the relative effects of external fixation and intramedulllary nailing. Further studies are needed to determine these effects , especially for patients who have GustiloШ C fractures.
【摘要】 目的 比较胫骨平台骨折术后辅助与不辅助持续被动运动（continuous passive motion，CPM）的临床疗效。 方法 对2008年6月-2009年6月86例行手术治疗的闭合性、无合并损伤的胫骨平台骨折患者进行回顾性分析。根据是否辅助CPM分为CPM组27例和非CPM组（对照组）59例。对两组患者的伤口愈合情况，膝关节屈曲、伸直角度，以及膝关节功能恢复情况进行比较。 结果 两组伤口甲级愈合率差异无统计学意义（P=0.566）。在术后2周和6周，CPM组患者的膝关节屈曲角度明显大于对照组（Plt;0.001），但在术后3个月和12个月，两组的差异无统计学意义（P=0.219，P=0.512）。在术后2、6周，3、12个月，CPM组和对照组患者的膝关节伸直角度差异无统计学意义。在术后12个月的Rasmussen膝关节功能评分方面，CPM组和对照组的差异无统计学意义。 结论 胫骨平台骨折术后辅助CPM能早期提升膝关节屈曲角度，但并不能提高远期的膝关节活动度和最终的膝关节功能。【Abstract】 Objective To compare the therapeutic effect of continuous passive motion (CPM) treatment after tibial plateau fractures operation. Methods From June 2008 to June 2009, 86 patients were treated due to closed tibial plateau fractures without combined injuries. The patients were treated with (27 patients, CPM group) and without (59 patients, control group) CPM. The wound healing rates, range of motion and the knee function were compared between the two groups. Results There was no significant difference between the two groups in wound healing rates (P=0.566). Two and six weeks after the operation, there were significant differences between the two groups in flexion degree (Plt;0.001); three and 12 months after the operation, there were no significant differences between the two groups (P=0.219, P=0.512). At the 2nd and 6th week, 3rd and 12th month postoperatively, there were no significant differences between the groups in extension degree. Twelve months after the operation, there were no significant differences between the groups in functional recovery of the knee. Conclusion CPM in the post-operative treatment of tibial plateau fractures is effective increasing knee flexion in the early stage, but is not effective increasing range of motion or knee function in a long term.
Objective To investigate the effectiveness of shortening-lengthening method using Ilizarov technique for repairing large tibial bone and soft tissue defects. Methods Between January 2006 and December 2011, 12 patients with large tibial bone and soft tissue defects were treated by shortening-lengthening method using Ilizarov technique. There were 8 males and 4 females with an average age of 39.3 years (range, 18-65 years). The causes were injury in 8 cases and chronic infection in 4 cases. The area of soft tissue defect was 5 cm × 4 cm to 20 cm × 16 cm, and the length of tibial bone defect was 4.5-8.0 cm with an average of 6.2 cm. Results Incision in the lengthening area healed by first intention; healing of wounds by first intention was achieved in 6 cases, delayed healing in 2 cases, and secondary healing in 4 cases, with no common peroneal nerve injury. All patients were followed up 18-54 months with an average of 29 months. In the lengthening area, the bone healing time was 180-365 days (mean, 267 days), and the healing index was 3.8-4.3 days/mm (mean, 4.1 days/mm). In the shortening area, the bone healing time was 195-380 days (mean, 297 days) in the others except 1 case who was repaired with bone grafting. Mild pin-related infection and loosening were observed in all cases, but no infection occurred in the lengthening or shortening area. At last follow-up, weight bearing of the leg was fully recovered in 12 cases. According to Mazur’s criteria, the function of ankle was excellent in 2 cases, good in 6 cases, and fair in 4 cases. Nine patients had equal limb length, and 3 patients had shortened length less than 2 cm. Conclusion Shortening-lengthening method using Ilizarov technique has the advantages of simple surgery, less complications, easy to close the wound, and good effectiveness in repairing of large tibial bone and soft tissue defects．
Objective To describe a surgical device for closed reduction of tibial fracture and investigate its clinical effectiveness. Methods Between June 2010 and December 2012, 24 cases of tibial fractures were treated with intramedullary nailing using a surgical device for closed reduction. There were 18 males and 6 females with an average age of 40 years (range, 20-64 years). All fractures were closed. There were 3 proximal third fractures, 12 middle third fractures, and 9 distal third fractures. According to AO classification, 12 cases were classified as type A, 8 cases as type B, and 4 cases as type C. The mean time between injury and operation was 3 days (range, 1-12 days). The intraoperative fluoroscopy frequency to confirm closed reduction and guide wire passing the fracture site, and the duration between fracture reduction and nail insertion were recorded. The injured limb alignment and fracture angular deformity were measured as described by Freedman et al. The fuction of affected limb was estimated by Johner-Wruhs criteria. Results Closed reduction was successfully performed in 24 patients. The mean fluoroscopy frequency to confirm closed reduction was 3 (range, 2-5). The fluoroscopy frequency to confirm guide wire passing the fracture site was 2. The mean duration between fracture reduction and nail insertion was 30 minutes (range, 20-42 minutes). No intraoperative or postoperative complication occurred, such as infection, vessel and nerve injuries. All incisions healed by first intention. Seventeen patients were followed up 6-16 months (mean, 10 months). Radiographic evidence showed that bridging callous was observed at 2-4 months (mean, 2.5 months). The injured limb alignment was normal on anteroposterial and lateral radiographs at 5 months postoperatively, no malalignment and obvious angular deformity was observed. The internal fixator had good position. According to Johner-Wruhs criteria for evaluation of the affected limb function, the results were excellent in 12 cases and good in 5 cases with an excellent and good rate of 100%. Conclusion The surgical device for closed reduction of tibial fracture is simple and easy to use, and has good effectiveness combined with intramedullary nailing.
Objective To compare the clinical results of locking compress plate (LCP) as an external fixator and standard external fixator for treatment of tibial open fractures. Methods Between May 2009 and June 2012, 59 patients with tibial open fractures were treated with LCP as an external fixator in 36 patients (group A), and with standard external fixator in 23 patients (group B). There was no significant difference in gender, age, cause of injury, affected side, type of fracture, location, and interval between injury and surgery between 2 groups (P gt; 0.05). The time of fracture healing and incision healing, the time of partial weight-bearing, the range of motion (ROM) of knee and ankle, and complications were compared between 2 groups. Results The incidence of pin-track infection in group A (0) was significantly lower than that in group B (21.7%) (P=0.007). No significant difference was found in the incidence of superficial infection and deep infection of incision, and the time of incision healing between 2 groups (P gt; 0.05). Deep vein thrombosis occurred in 5 cases of group A and 2 cases of group B, showing no significant difference (χ2=0.036, P=0.085). All patients were followed up 15.2 months on average (range, 9-28 months) in group A, and 18.6 months on average (range, 9-47 months) in group B. The malunion rate and nonunion rate showed no significant difference between groups A and B (0 vs. 13.0% and 0 vs. 8.7%, P gt; 0.05); the delayed union rate of group A (2.8%) was significantly lower than that of group B (21.7%) (χ2=5.573, P=0.018). Group A had shorter time of fracture healing, quicker partial weight-bearing, greater ROM of the knee and ankle than group B (P lt; 0.05). Conclusion The LCP external fixator can obtain reliable fixation in treating tibial open fracture, and has good patients’ compliance, so it is helpful to do functional exercise, improve fracture healing and function recovery, and reduce the complication incidence.
Objective To compare the effectiveness between minimally invasive plate osteosynthesis (MIPO) and open reduction and internal fixation (ORIF) for treatment of extra-articular distal tibial fracture. Methods Between March 2009 and March 2012, 57 patients with extra-articular distal tibial fractures were treated, and the clinical data were retrospectively analyzed. Of 57 cases, 31 were treated with MIPO (MIPO group), and 26 with ORIF (ORIF group). There was no significant difference in gender, age, cause of injury, type of fractures, complication, and time from injury to operation between 2 groups (P gt; 0.05). The operation time, intraoperative blood loss, fracture healing time, and complications were compared between 2 groups. Results There was no significant difference in operation time and intraoperative blood loss between 2 groups (P gt; 0.05). Wound infection occurred in 5 cases [2 in MIPO group (6.5%) and 3 in ORIF group (11.5%)], showing no significant difference (χ2=0.651, P=0.499). The other wound obtained healing by first intention. All cases were followed up 13-24 months (mean, 15 months). No significant difference was found in the average healing time between 2 groups and between patients with types A and B by AO classification (P gt; 0.05); in patients with type C, the healing time in MIPO group was significantly shorter than that in ORIF group (t= — 2.277, P=0.033). Delayed union was observed in 3 cases of MIPO group (9.7%) and in 4 cases of ORIF group (15.4%), showing no significant difference (χ2=0.428, P=0.691). Mal-union occurred in 4 cases of MIPO group (12.9%) and in 1 case of ORIF group (3.8%), showing no significant difference (χ2=1.449, P=0.362). No significant difference was found in Mazur score between 2 groups (t=0.480, P=0.633). The excellent and good rate was 93.5% in MIPO group (excellent in 24 cases, good in 5 cases, fair in 1 case, and poor in 1 case) and was 92.3% in ORIF group (excellent in 18 cases, good in 6 cases, and poor in 2 cases), and the difference was not significant (Z= — 0.687, P=0.492). Conclusion Both MIPO and ORIF have good results in treating extra-articular distal tibial fractures. MIPO is superior to ORIF for treating complex and communited fractures.
Objective To investigate the improved reduction technique for depression fractures of the lateral tibial plateau and its effectiveness. Methods Between January 2008 and December 2010, 48 patients (48 knees) with depression fractures of the lateral tibial plateau (Schatzker II or III fractures) were treated. There were 32 males and 16 females with an average age of 45.8 years (range, 16-79 years). All fractures were fresh closed fractures, which were caused by traffic accident in 27 cases, by falling from height in 5 cases, by crushing in 8 cases, and by sustained falls in 8 cases. According to Schatzker classification, 29 cases were classified as type II and 19 cases as type III. The lateral cortex was cut off to expose the depression and compacted cancellous bone was elevated to reset the articular surface. After reduction, autologous iliac bone graft and locking plate internal fixation were used. Results Healing of incision by first intention was achieved in all patients, and no complication occurred. All patients were followed up 1.7 years on average (range, 1-3 years). At last follow-up, the knee extension was ( — 0.5 ± 0.3)°, and the knee flexion was (136.9 ± 8.8)°. X-ray films showed that the fracture healing time was 52 weeks and no breakage of internal fixation occurred. According to Rasmussen clinical score, the results were excellent in 35 cases, good in 10 cases, and fair in 3 cases. According to Rasmussen radiographical score, the results were excellent in 41 cases, good in 7 cases; there were 41 excellent scores and 7 good scores of articular reduction; all gained good recovery of coronal and sagittal alignment and condylar width. The articular surface collapse was (1.0 ± 0.7) mm at immediate postoperatively and (1.2 ± 0.7) mm at last follow-up, showing no significant difference (t= — 1.42, P=0.20), but significant differences were found when compared with that at preoperation [(12.2 ± 8.0) mm, P lt; 0.05]. Conclusion This improved technique can provide a satisfactory effectiveness of fracture reduction and can avoid loss of reduction. The short-term effectiveness is good, but futher follow-up is necessary to determine the long-term results.
Objective To observe the effectiveness of the superior fibular head approach for the treatment of posterolateral fracture of the tibial plateau. Methods Between June 2010 and February 2012, 20 cases of posterolateral fracture of the tibial plateau were treated through superior fibular head approach, including 1 case of simple posterolateral fracture of the tibial plateau and 19 cases of posterolateral fracture of the tibial plateau with other fractures. There were 12 males and 8 females with an average age of 42.2 years (range, 28-58 years). All patients had closed fractures. Fracture was caused by traffic accident in 14 cases, by falling from height in 4 cases, and by twist injury in 2 cases. Associated injuries included lateral meniscus injury in 5 cases, medial meniscus injury in 2 cases, and anterior cruciate ligament injury in 1 case. The time from injury to admission ranged from 90 minutes to 32 hours (mean, 4.5 hours), and the time from admission to operation was 5-12 days (mean, 7.8 days). All cases underwent fracture reduction and fixation with Pilon plates through the superior fibular head approach, and associated fracture and meniscal injury were treated. Results All incisions healed by first intention, and no numbness or articular instability occurred. All patients were followed up 6-26 months (mean, 19.1 months). The average fracture healing time was 10.2 weeks (range, 8-12 weeks). During following-up, no related complication of fixation loosening or articular surface loss occurred. According to Rasmussen knee score criteria at last follow-up, the score was 18-30 (mean, 27.9); 16 cases were graded as excellent, 3 cases as good, and 1 case as fair, with an excellent and good rate of 95%. Conclusion The superior fibular head approach for the treatment of posterolateral fracture of the tibial plateau is simple, safe, and effective, and can achieve a good surgical outcome.
Objective To investigate the effectiveness of tissue transplantation combined with bone transmission in treatment of large defects of tibial bone and soft tissue. Methods Between February 2006 and February 2011, 15 cases of traumatic tibia bone and soft tissue defects were treated. There were 12 males and 3 females, aged from 16 to 54 years (mean, 32 years). After internal and external fixations of fracture, 11 patients with open fracture (Gustilo type III) had skin necrosis, bone exposure, and infection; after open reduction and internal fixation, 2 patients with closed fracture had skin necrosis and infection; and after limb replantation, 2 patients had skin necrosis and bone exposure. The area of soft tissue defect ranged from 5 cm × 5 cm to 22 cm × 17 cm. Eight cases had limb shortening with an average of 3.5 cm (range, 2-5 cm) and angular deformity. The lenghth of bone defect ranged from 4 to 18 cm (mean, 8 cm). The flap transplantation and skin graft were used in 9 and 6 cases, respectively; bone transmission and limb lengthening orthomorphia were performed in all cases at 3 months after wound healing; of them, 2 cases received double osteotomy bone transmission, and 14 cases received autologous bone graft and reset after apposition of fracture ends. Results All flaps and skin grafts survived; the wound healed at 3.5 months on average (range, 3 weeks-18 months). The length of bone lengthening was 6-22 cm (mean, 8 cm). The time of bone healing and removal of external fixation was 9.5-39.0 months (mean, 15 months). The healing index was 40-65 days/cm (mean, 55 days/cm). All patients were followed up 1-5 years (mean, 4 years). The wounds of all the cases healed well without infection or ulceration. The functions of weight-bearing and walking were recovered; 6 cases had normal gait and 9 cases had claudication. The knee range of motion was 0° in extention, 120-160° in flexion (mean, 150°). According to the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system for ankle function, the results were excellent in 7 cases, good in 4 cases, and fair in 4 cases, with an excellent and good rate of 73.3%. Conclusion Tissue transplantation combined with bone transmission is an effective method to treat large defects of soft tissue and tibial bone, which can increase strength of bone connection and reduce damage to the donor site.
