Objective To compare the outcomes between intramedullary nail change and augmentation plating with a retained intramedullary nail for aseptic nonunion of femoral shaft fractures after femoral nailing, and to analyze the cause so as to guide the clinical application. Methods Between June 2001 and June 2011, 28 patients with aseptic nonunion of femoral shaft fractures after femoral nailing were treated with intramedullary nail change (11 patients, group A) and augmentation plating with a retained intramedullary nail (17 patients, group B), and the clinical data were analyzed retrospectively. There was no significant difference in age, gender, smoking, location of fracture, Association for the Study of Internal Fixation (AO/ASIF) classification, type of injury, associated injury, type of nonunion, and time of nonunion between 2 groups (P gt; 0.05). The patients were followed up by imaging and the clinical function at regular intervals to observe the callus growth and the recovery condition of the affected limb function, and clinical curative effectiveness was evaluated by Tohner-Wrnch standard. Results The operation time, intraoperative bleeding volume, and intraoperative erythrocyte-transported volume in group A were significantly higher than those in group B (P lt; 0.05). There was no significant difference in postoperative drainage volume and hospitalization days between 2 groups (P gt; 0.05). All the incisions healed by first intention, and no nerve and blood vessel injury occurred. All patients were followed up 18.6 months on average (range, 12-36 months). All cases obtained bone union, and time of clinical and radiological bone healing in group B was significantly shorter than those in group A (P lt; 0.05). During follow-up, no following complication occurred: deep incision infection, injuries of blood vessels and nerves, loosening and breakage of internal fixation, loss of reduction, angulated and rotational malunion. According to Tohner-Wrnch standard at last follow-up, the results were excellent in 6 cases, good in 3 cases, and poor in 2 cases, with an excellent and good rate of 81.8% in group A; the results were excellent in 12 cases, good in 5 cases, with an excellent and good rate of 100% in group B; and difference was significant between 2 groups (Z= — 2.623, P=0.021). Conclusion Augmentation plating with a retained intramedullary nail is an ideal treatment for aseptic nonunion of femoral shaft fractures after femoral nailing and can achieve satisfactory clinical outcomes because it has simpler operation, shorter operation time, less blood loss, and less trauma than intramedullary nail change.

【Abstract】 Objective To discuss the techniques and advantages of closed reduction and intramedullary nail ing intreating femoral shaft fracture without cannulated femoral reamer. Methods From January 2006 to June 2007, 24 cases offemoral shaft fracture were treated with closed reduction and intramedullary nail ing. Among them, there were 14 males and 10 females, with the average age of 38.3 years (ranging from 18 years to 63 years), with 7 left legs and 17 right legs. The average course of the disease was 7.6 days (ranging from 3 days to 20 days). According to the AO typing, there were 5 cases of type A, 6 of type B, 7 of type C1, 2 of type C2 and 4 of type C3. Closed reduction was achieved with manipulation and reaming of femoral canal was instructed by fluoroscopy. Results The operation time lasted from 100 minutes to 170 minutes, with the average time of 128.3 minutes. One patient was given a transfusion of 400 mL, and others were not. Twenty cases were followed up with the average time of 13.1 months (ranging from 6 months to 24 months). A mild to large amount of bony callus was showed on X-ray films 6 to 12 weeks postoperatively. Walking without crutches began at the average week of 22.2 (ranging from 15 to 30) postoperatively. Range of motion of the knee was 0° to 145.5°. No infection or break of the internal fixator occurred. Myositis ossificans with pain and insufficient flexion of hip (120°) happened in 1 case and the pain disappeared after non-steroid anti-inflammatory drugs were taken. Nonsymptomatic myositis ossificans occurred in 2 cases and no treatment was needed. Conclusion Closed reductionand intramedullary nail ing can help to protect the blood supply of fracture fragments and provide central fixation. The operation process will be more compl icated if cannulated femoral reamer is not available.
ObjectiveTo review the history, current situation, and progress of augmentation plate (AP) for femoral shaft nonunion after intramedullary nail fixation.MethodsThe results of the clinical studies about the AP in treatment of femoral shaft nonunion after intramedullary nail fixation in recent years were widely reviewed and analyzed.ResultsThe AP has been successfully applied to femoral shaft nonunion after intramedullary nail fixation since 1997. According to breakage of the previous nailing, AP is divided into two categories: AP with retaining the previous intramedullary nail and AP with exchanging intramedullary nail. AP is not only suitable for simple nonunion, but also for complex nonunion with severe deformity. Compared with exchanging intramedullary nail, lateral plate, and dual plate, AP has less surgical trauma, shorter healing time, higher healing rate, and faster returning to society. However, there are still some problems with the revision method, including difficulty in bicortical screw fixation, lack of anatomic plate suitable for femoral shaft nonunion, and lack of postoperative function and quality of life assessment.ConclusionCompared with other revision methods, AP could achieve higher fracture healing rate and better clinical prognosis for patients with femoral shaft nonunion. However, whether patients benefit from AP in terms of function and quality of life remain uncertain. Furthermore, high-quality randomized controlled clinical studies are needed to further confirm that AP are superior to the other revision fixations.
Objective To explore the value of electromagnetic navigation interlocking intramedullary nail in the treatment of femoral shaft fracture. Methods Between July 2012 and October 2013, 53 cases of femoral shaft fracture were treated. There were 40 males and 13 females, aged 16-52 years (mean, 38.3 years). The causes of injury were traffic accident in 28 cases, falling from height in 11 cases, falling in 7 cases, crush injury in 4 cases, and other in 3 cases. Of 53 cases, there were 3 cases of open fracture (Gustilo I degree) and 50 cases of closed fracture. Fracture was located in the proximal femur in 17 cases, middle femur in 29 cases, and distal femur in 7 cases. According to Winquist classification, 7 cases were rated as type I, 8 cases as typeⅡ, 22 cases as typeⅢ, and 16 cases as type IV; according to AO classification, 18 cases were rated as type 32-A, 28 cases as type 32-B, and 7 cases as type 32-C. The time from injury to operation was 3-11 days (mean, 5 days). Distal interlocking intramedullary nail was implanted using electromagnetic navigation. Results The distal locking nail operation with interlocking intramedullary nail was successfully completed under electromagnetic navigation; the one-time success rate of distal locking nail operation reached 100%; and the locking nail time was 5.0-9.5 minutes (mean, 7.0 minutes). Healing of incision by first intention was obtained after operation, and no complication of skin necrosis, infection, and sinus tract occurred. Fifty-three cases were all followed up 5-12 months (mean, 9 months). One case had hip pain and weaken middle gluteal muscle strength, and the symptoms disappeared after removing the nail. During the follow-up period, no broken nails, nail exit, infection, or re-fracture occurred. All fractures achieved clinical healing, and the healing time was 8-22 weeks (mean, 14.5 weeks). In 49 patients followed up 8 months, the Lysholm score was excellent in 44 cases, good in 4 cases, and acceptable in 1 case, with an excellent and good rate of 98%. Conclusion Electromagnetic navigation system is safe and reliable, with the advantages of high positioning accuracy, short operation time, and no radiation, the clinical application of the system for distal locking nail operation can obtain excellent short-term effectiveness.
Objective To explore the effectiveness of Ilizarov external fixation without bone graft in the treatment of atrophic femoral shaft nonunion. Methods The clinical data of 12 patients with atrophic femoral shaft nonunion admitted between October 2010 and January 2017 were retrospectively analyzed. There were 8 males and 4 females, aged from 24 to 61 years, with an average age of 41.7 years. The nonunion sites located in the middle and upper femur in 7 cases and in the distal femur or supracondylar in 5 cases. The disease duration ranged from 1 to 9 years, with an average of 3.7 years. Previous operations ranged from 1 to 9 times, with an average of 2.8 times. The original fixator was removed, the fracture end of nonunion was debrided, and Ilizarov external fixator was installed. In patients with the length of bone defect less than 4 cm, direct compression fixation was performed during operation; in patients with limb shortening more than 2.5 cm, proximal femoral osteotomy and bone lengthening components were required to prepare limb lengthening after operation; all patients did not receive bone graft. The wearing time of external fixator, clinical bone healing time of nonunion fracture end, and complications were recorded. The effectiveness was evaluated by Paley’s nonunion evaluation criteria. Results All patients were followed up 24-50 months, with an average of 30 months. Bony union was achieved in all 12 cases with a healing time of 6.0-23.5 months (mean, 11.5 months). The wearing time of external fixator ranged from 7 to 25 months, with an average of 13.5 months. At last follow-up, according to Paley’s nonunion evaluation criteria, the results were excellent in 6 cases, good in 4 cases, and fair in 2 cases, with an excellent and good rate of 83.3%. Sagittal angulation deformity of femur more than 7° occurred in 4 cases, with no significant effect on knee extension function, and no special treatment such as osteotomy was performed. Two patients had shorter limbs (>2.5 cm) after operation and were replaced by high shoes; 4 patients with trans-knee fixation lost knee joint mobility of 10-30° after operation; 10 cases of needle tract infection occurred, of which 4 cases with infection and loosening of fixed needle were replaced and re-fixed after needle extraction, the remaining 6 cases of infection without loosening of fixed needle were controlled by local dressing change, needle nursing, and oral cephalosporin anti-inflammatory drugs. No complications such as deep infection and vascular nerve injury occurred. Conclusion Ilizarov external fixation has a high healing rate for atrophic femoral shaft nonunion, which is relatively minimally invasive and can avoid bone grafting. Its preliminary effectiveness is exact, and it is also effective for patients who have experienced multiple failed operations. It is necessary to pay attention to the nursing and rehabilitation training after external fixation.
