Abstract
PURPOSE To methodically assess the effectiveness of augmentative plating (AP) and exchange nailing (EN) in managing nonunion following intramedullary nailing for long bone fractures of the lower extremity. METHODS PubMed, EMBASE, Web of Science, and the Cochrane Library were searched to gather clinical studies regarding the use of AP and EN techniques in the treatment of nonunion following intramedullary nailing of lower extremity long bones. The search was conducted up until May 2023. The original studies underwent an independent assessment of their quality, a process conducted utilizing the Newcastle-Ottawa scale. Data were retrieved from these studies, and meta-analysis was executed utilizing Review Manager 5.3. RESULTS This meta-analysis included 8 studies involving 661 participants, with 305 in the AP group and 356 in the EN group. The results of the meta-analysis demonstrated that the AP group exhibited a higher rate of union (odds ratio: 8.61, 95% confidence intervals (CI): 4.12 - 17.99, p < 0.001), shorter union time (standardized mean difference (SMD): -1.08, 95 % CI: -1.79 - -0.37, p = 0.003), reduced duration of the surgical procedure (SMD: -0.56, 95 % CI: -0.93 - -0.19, p = 0.003), less bleeding (SMD: -1.5, 95 % CI: -2.81 - -0.18), p = 0.03), and a lower incidence of complications (relative risk: -0.17, 95 % CI: -0.27 - -0.06, p = 0.001). In the subgroup analysis, the time for union in the AP group in nonisthmal and isthmal nonunion of lower extremity long bones was shorter compared to the EN group (nonisthmal SMD: -1.94, 95 % CI: -3.28 - -0.61, p < 0.001; isthmal SMD: -1.08, 95 % CI: -1.64 - -0.52, p = 0.002). CONCLUSION In the treatment of nonunion in diaphyseal fractures of the long bones in the lower extremity, the AP approach is superior to EN, both intraoperatively (with reduced duration of the surgical procedure and diminished blood loss) and postoperatively (with an elevated union rate, shorter union time, and lower incidence of complications). Specifically, in the management of nonunion of lower extremity long bones with non-isthmal and isthmal intramedullary nails, AP demonstrated shorter union time in comparison to EN.

Abstract
INTRODUCTION Tibia fractures are the most common long bone injuries encountered in the trauma population. The majority are treated successfully but non-union remains a common complication. A systematic review of current evidence regarding the management for aseptic diaphyseal tibial non-unions was undertaken. METHODS A systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), was conducted. RESULTS A total of 632 publications were screened for inclusion. Full text review of 91 studies resulted in 26 publications being retained for final review. The majority of patients included in the studies either underwent exchange nailing (n=315) or primary intramedullary nailing (n=174) with respective union rates of 88% and 95% being achieved. The highest union rate (97%) was achieved with the use of fine wire external fixation. The major adjuvant treatment modalities were fibula osteotomies (n=372; 41%), fixation dynamization (n=208; 23%) and bone grafting (n=183; 20%). CONCLUSION The lack of standardization in reporting of outcomes and the diversity of management strategies employed precludes definitive conclusions or recommendations. Further research is required to ascertain the ideal treatment strategy in the management of aseptic tibial diaphyseal non-unions. LEVEL OF EVIDENCE IV.

Abstract
In aseptic tibial diaphyseal nonunions after failed conservative treatment, the recommended treatment is a reamed intramedullary (IM) nail.Typically, when an aseptic tibial nonunion previously treated with an IM nail is found, it is advisable to change the previous IM nail for a larger diameter reamed and locked IM nail (the rate of success of renailing is around 90%).A second change after an IM nail failure is also a good option, especially if bone healing has progressed after the first change.Fibular osteotomy is not routinely advised; it is only recommended when it interferes with the nonunion site.In delayed unions before 24 weeks, IM nail dynamization can be performed as a less invasive option before deciding on a nail change.If there is a bone defect, a bone graft must be recommended, with the gold standard being the autologous iliac crest bone graft (AICBG).A reamer-irrigator-aspirator (RIA) system might also obtain a bone autograft that is comparable to AICBG.Although the size of the bone defect suitable to perform bone transport techniques is a controversial issue, we believe that such techniques can be considered in bone defects > 3 cm.Non-invasive therapies and biologic therapies could be applied in isolation for patients with high surgical risk, or could be used as adjuvants to the aforementioned surgical treatments.

Abstract
BACKGROUND Treatment of tibial diaphyseal nonunions are rather difficult. Plate-screw, intramedullary nailing and external fixation are the methods used for treatment. The aim of this study is to evaluate the treatment results of aseptic diaphyseal nonunions following tibia fractures by intramedullary compressive tibia nailing (IMCN) with or without bone graft. MATERIALS AND METHODS Twenty eight patients who had aseptic tibial nonunion without bone defects operated between 2005 and 2015 were included in the study. The mean age of our patients was 36.4 years (range 20-56 years). There were 22 males and 6 females. Fifteen of the patients exhibited hypertrophic nonunion and thirteen exhibited atrophic nonunion. The average time between fracture occurrence and presentation to our department was 1.6 years (range 1-20 years). All patients underwent fibular osteotomy by removal of a 2 cm bone block from the middle one-third of the fibulas. In all cases, IMCN was applied following the reaming procedure, then maximum bone contacts were achieved manually between proximal and distal bone fragments afterward, and dynamic compressive fixation with 1 mm of compression was performed by a single rotation of the compression screw at the top of the nail. Direct X-ray images were assessed according to the Rust criteria, and functional outcomes were assessed according to the Johner-Wrush criteria. Finite-element analysis was performed for 1 mm of compression. For statistical analysis, Fisher's exact test, Pearson's Chi-square test, and Mann-Whitney U-test were used. RESULTS Union was achieved in all patients. Radiological union was obtained at an average of 15.5 ± 1.86 weeks. Functional results were found to be good or excellent in 25 (89.2%) patients and average or poor in 3 (10.8%) patients. One patient developed skin necrosis at the wound site, which was treated with rotational flap and skin graft. None of the patients developed implant failure, thromboembolism, deep-vein thrombosis, or infection. CONCLUSIONS The use of compressive intramedullary nailing with or without bone graft is an effective method for the treatment of tibial nonunion.

Abstract
PURPOSE We present the results of a study on the anatomy of the ascending branch of the lateral circumflex femoral artery (AB-LCFA) and the use of the pedicled iliac bone flap transfer perfused by AB-LCFA combined with external fixation for the treatment of the nonunion of upper femoral shaft fractures. METHODS The orientation, diameter, length, and distribution of the AB-LCFA from 40 lower limbs of adult cadavers were dissected and measured. From 2000 to 2012, 13 patients with nonunion of upper femoral shaft fractures underwent pedicled iliac bone flap transfer perfused by the AB-LCFA combined with external fixation. The time of bone fracture union was recorded based on X-ray examination. The functional results of the femoral shaft were evaluated by the Klemm classification. RESULTS The lateral circumflex femoral artery (LCFA) divided into ascending, transverse, and descending branches in 32 specimens (80%). The diameter of the AB-LCFA at the origin was 3.15 ± 0.9 mm and the length of the AB-LCFA was 8.51 ± 3.06 cm. The postoperative course of the procedure was uneventful in all 13 patients. The average follow-up was 15 months. Bone union was achieved in all patients and the average union time was 5.3 months. 12 patients achieved excellent or good functional results based on the Klemm classification. CONCLUSION The AB-LCFA has a consistent orientation and abundant blood flow. The transfer of the iliac crest bone flap perfused by the AB-LCFA while combined with external fixation could be an option for treating the nonunion of upper femoral shaft fractures.

Abstract
OBJECTIVES This multicenter study was designed to evaluate whether tibia fracture nonunions treated with exchange nailing proceed to union faster with dynamically- versus statically-locked nails, or with fibular osteotomy versus no fibular osteotomy. DESIGN Retrospective, chart-review, multicenter study. SETTING Multicenter review of 6 level 1 trauma centers. PATIENTS/PARTICIPANTS Patients who had a tibia fracture treated with an intramedullary nail that progressed to nonunion, and were subsequently treated with exchange nailing, were identified. All patients that met inclusion criteria and subsequently progressed to union were included in the study. INTERVENTION Patients underwent tibial exchange nailing to repair nonunions, with screws in either a dynamically- or statically-locked configuration with or without fibular osteotomy. MAIN OUTCOME MEASURES The primary outcome measure was a comparison of time to healing of tibial nonunion comparing different screw configurations and fibular osteotomy. RESULTS Fifty-two patients underwent an exchange nail procedure and their outcomes were used for the primary analysis. Patients with dynamically-locked nails proceeded to union 7.9 months after revision surgery compared with 7.3 months for those with statically-locked nails, but this was not statistically significant (P = 0.68). Patients with fibular osteotomy proceeded to union 2.9 months faster than those without fibular osteotomy, and this trended toward significance (P = 0.067). Obese patients healed on average 8.8 months after surgery compared with 6.8 months for nonobese patients (P = 0.27). Closed fractures healed after 6.4 months compared with 7.7 months for open fractures (P = 0.40). CONCLUSIONS There was no significant difference in time to union between patients who had a dynamic screw configuration compared with a static screw configuration for their exchange nail. Patients who underwent fibular osteotomy proceeded to union faster than those without an osteotomy. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
Femoral midshaft fracture is one of the most common clinical injuries and is often caused by high-energy traffic accidents. Intramedullary nailings, plates, and external fixators are all used as treatment alternatives for a variety of patients depending on fracture location, displacement, comminution, soft tissue condition, and local tradition. Locked intramedullary nailing is currently the preferred treatment method for most diaphyseal fractures and has good clinical results. The goal of this study was to compare expandable and locked intramedullary nailing for the treatment of AO type 32A and 32B1 femoral midshaft fractures. The authors performed a retrospective analysis of 46 patients (33 men and 13 women; mean age, 32.3 years; range, 22-52 years) with femoral midshaft fractures who were divided into 2 groups-one treated with an expandable intramedullary nailing method and the other with a conventional locked intramedullary nailing. The 2 groups were compared with respect to operation time, fluoroscopic time, amount of estimated blood loss, hospitalization time, healing time, and complications. Patients were followed for at least 1 year. The results of this study showed that all of the patients achieved bone union within 12 to 24 months. Expandable nailing performed better than locked nailing in operation time, fluoroscopic time, amount of estimated blood loss, and healing time (P<.001). There was no difference in hospitalization time and no visible shortening or severe complications were observed in either group. Based on the results of this study, the expandable intramedullary nailing is an easy and effective treatment for AO type 32A and 32B1 diaphyseal femoral fractures.

Treatment of the femoral shaft nonunion with double plate fixation and bone grafting: A case series of 14 patients. Injury 2015; 46:1102-7.

Abstract
INTRODUCTION The management of femoral shaft nonunion still remains a challenge in orthopaedic surgery. It represents a serious postoperative problem for the patient, associated with plate breakage and loosening, bone defect, shortening deformity and infection. A double plate fixation combined with bone grafting may become a promising therapeutic strategy for the treatment of patients with femoral shaft nonunion. In this study, our goal was to evaluate the clinical outcome of a novel approach for 14 consecutive patients with femoral shaft nonunion using double plate fixation with bone grafting. METHODS Retrospective data from June 2010 to August 2012 were obtained from records for 14 consecutive femoral shaft aseptic nonunion patients treated with double plate fixation combined with bone grafting. Nine patients were men and five patients were woman and average age of the patients was 26 years (range from 22 to 32 years). The mean time since injury was 26.2 months. The nonunion had resulted from repeated internal fixation failure (including plate or intramedullary nail fixation) in nine cases and primary internal fixation in five cases. RESULTS All the 14 patients were followed up for an average of 14.8 (10-25) months. All cases achieved bony union without wound infection or fixation failure and the mean time to union was 5.2 months (range 4-7 months). CONCLUSION Double plate fixation and bone grafting are a promising method for femoral shaft nonunion. In addition, this strategy is useful for such a nonunion caused by a repeated plate or intramedullary nail fixation failure with bone defect due to its strong stability with three-dimensional fixation and fully bone graft availability.

Abstract
OBJECTIVE The purpose of this study was to determine if surgeons could reliably predict if patients with tibia fractures treated with intramedullary nails will proceed to nonunion based on their clinical scenario and radiographs at 3 months. DESIGN Blinded randomized questionnaire based on a retrospective cohort. SETTING University level 1 trauma center. PATIENTS/PARTICIPANTS Fifty-six patients who underwent intramedullary fixation for tibia fractures with incomplete healing at 3 months. METHODS A questionnaire was applied to 56 consecutive patients treated between 2005 and 2009 with intramedullary fixation for tibia fractures who had incomplete healing at 3 months. Each case was developed into a vignette that included the 3-month radiographs and detailed clinical histories. The questionnaire was distributed to 3 fellowship-trained trauma surgeons who were asked to predict if the fracture would go onto nonunion. MAIN OUTCOME MEASUREMENTS Diagnostic accuracy of predicting nonunion in patients with incomplete healing of their tibia fracture at 3 months. RESULTS The combined overall diagnostic accuracy of all 3 surgeons was 74%. Sensitivity and specificity was 62% and 77%, respectively. Radiographic features and injury mechanism were the most commonly cited clinical information used to predict fracture healing. The average positive predictive value was 73%. In 9 patients with diabetes, the diagnostic accuracy was 88%. CONCLUSIONS Clinical judgment at 3 months allows for correct prediction of eventual nonunion development in a majority of patients. We suggest that analysis of the entire clinical picture be used to predict fracture healing at 3 months. A protocol of waiting for 6 months before reoperation in all patients treated with intramedullary nailing for tibia fractures may subject patients to prolonged disability and discomfort.

Abstract
The objective of this article is to systematically review the currently available literature to formulate evidence-based guidelines for the treatment of femoral shaft nonunions for clinical practice and to establish recommendations for future research. Articles from PubMed/MEDLINE, Cochrane Clinical Trial Register, and EMBASE, that presented data concerning treatment of nonunions of femoral shaft fractures in adult humans, were included for data extraction and analysis. The search was restricted to articles from January 1970 to March 2011 written in the English, German, or Dutch languages. Articles containing data that were thought to have been presented previously were used once. Reports on nonunion after periprosthetic fractures, review articles, expert opinions, abstracts from scientific meetings, and case reports on 5 or fewer patients were excluded. The data that were extracted from the relevant articles included: type of nonunion, type of initial and secondary treatments, follow-up, union rate, and general complications. Most studies had different inclusion criteria and outcome measures, thus prohibiting a proper meta-analysis. Therefore, only the union rate and number of complications were compared between the different treatments. Methodological quality was assessed by assigning levels of evidence as previously defined by the Centre for Evidence-Based Medicine. This systematic review provides evidence in favour of plating if a nail is the first treatment; after failed plate fixation, nailing has a 96 % union rate. After failed nailing, augmentative plating results in a 96 % union rate compared to 73 % in the exchange nailing group.

Abstract
Nonunions of the femoral shaft represent a treatment challenge for the orthopaedic surgeon and a serious socioeconomic problem for the patient. Inadequate fracture stability, insufficient blood supply, bone loss or presence of infection are the main reasons for the development of a nonunion. Careful classification and exclusion of infection are crucial for the choice of the proper treatment alternative. Nail dynamization, primary intramedullary nailing or nail exchange, plate osteosynthesis and external fixation along with bone grafting, usage of bone substitutes and electrical stimulation can stimulate osseous union. A review of the aetiology, classification and treatment should prove helpful managing this serious complication.

Abstract
BACKGROUND Nonunion of long bones in lower limbs is a common complication of orthopedic trauma that can be extremely debilitating. This retrospective study describes our experience using expandable intramedullary nails and autologous bone grafting in treating lower limb long bone nonunion with bone defects. METHODS Nineteen patients (mean age 38.9 years, range 18-61) with lower limb long bone nonunion and defects caused by femoral or tibial fracture types were as follows: A2 (3 femoral, 1 tibial), A3 (1 femoral, 2 tibial), B2 (3 femoral, 4 tibial), and B3 (1 femoral, 4 tibial). Expandable intramedullary nailing and autologous bone (iliac and/or fibular) grafting were used for the treatment. Postoperative bone healing as determined by analysis of standard anteroposterior and lateral X-ray films every 4 weeks. Complications were noted. RESULTS The average number of previous surgeries was 1.9 (range 1-4). The mean duration from original injury to treatment was 17.6 months (range 9-40 months). Femoral shaft nonunion healed on average of 26.5 weeks (range 16-60 weeks) after surgery, while tibial shaft nonunion healed on average of 23.6 weeks (range 12-40 weeks) after surgery. Class I healing occurred in all but two patients who experienced chronic postoperative osteomyelitis and delayed wound healing, respectively. Two patients complained of postoperative donor site pain. CONCLUSIONS The use of expandable intramedullary nails and autologous bone grafts was an effective method for repair of nonunion of lower limb fractures combining with bone defects with minimal complications.

Abstract
Despite the continuous advances of surgical solutions, still 1-7% of fractures develop non-unions. The delays in fracture healing increase the period of incapacity of the patient with major consequences, on the psychological and functional recovery, but also on the direct and indirect health-related costs. In particular, femoral diaphyseal non-unions are often characterised by a challenging and long-lasting period of healing. The clinician treating these complex cases has to consider amongst other parameters, the condition of the soft tissue envelope, the adequacy of any pre-existing fixation, the alignment and length of the affected limb, the potential presence of an infection, as well as the general condition of the patient. Open reduction and plate fixation of femoral diaphyseal non-unions offers a valid alternative of stabilisation and if applied to carefully selected cases, can give optimal results.

Abstract
UNLABELLED Removal of intramedullary nails often is relegated to younger surgeons but may be difficult and challenging. We describe difficulties with removal of an incarcerated expandable femoral nail and a new technique for retrograde mobilization of an intramedullary nail through a small infrapatellar incision. No special device was necessary for successful implant removal. LEVEL OF EVIDENCE Level V, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Park K, Kim K, Choi YS. Comparison of mechanical rigidity between plate augmentation leaving the nail in situ and interlocking nail using cadaveric fracture model of the femur. INTERNATIONAL ORTHOPAEDICS 2010; 35:581-5. [PMID: 20213515 DOI: 10.1007/s00264-010-0983-y] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/19/2010] [Accepted: 02/04/2010] [Indexed: 12/13/2022]
Abstract
Thirteen matched pairs of cadaveric femurs were placed into two groups. In each group, a transverse fracture was created at a point 70% distal between the lesser trochanter and the adductor tubercle. One femur out of each matched pair was then stabilised with an interlocking intramedullary nail (nail only group) and the other femur was stabilised with plate augmentation after interlocking intramedullary nailing (plate augmentation group). The bending load to promote 5-mm displacement showed statistically significant differences between the plate augmentation group (mean 843.36 ± 409.13 N) and the nail only group (mean 315.02 ± 219.80 N) (p = 0.001). Torsional torque at the angle of 15 degrees showed statistically significant differences between the two groups; a mean of 2.09 ± 0.53 N·m for the plate augmentation group and a mean of 0.63 ± 0.46 N·m for the nail only group (p = 0.0001). We found a 2.6-fold increase in bending stiffness and a 3.3-fold increase in torsional stiffness in plate augmentation leaving a nail in situ compared to interlocking nailing only in the distal third fracture of femur.
