Abstract
BACKGROUND AND PURPOSE Intramedullary bone-lengthening nails have become increasingly popular. The 2 most used and successful nails are the FITBONE and the PRECICE nails. Uniform reporting is lacking on complications of intramedullary bone-lengthening nails. The purpose was therefore to assess and categorize the complications of lower limb bone-lengthening nails and investigate risk factors. PATIENTS AND METHODS We performed a retrospective review of patients operated on with intramedullary lengthening nails at 2 hospitals. We included only lower limb lengthening with FITBONE and PRECICE nails. Recorded patient data was patient demographics, nail information, and any complication. Complications were graded according to severity and origin classification. Complication risk factors were assessed with modified Poisson regression. RESULTS 314 segments in 257 patients were included. The FITBONE nail was predominantly used (75%), and most of the lengthenings were performed in the femur (80%). 53% of the patients had complications. 269 complications were identified in 175 segments (144 patients). Device-related complications were most frequent (0.3 complications/segment), followed by joint complications (0.2 complications/segment). An increased relative risk was found for complications in the tibia compared with the femur and for age groups above 30 years compared with the 10-19 years group. CONCLUSION Complications with intramedullary bone lengthening nails were more frequent than has previously been reported, with 53% of patients sustaining a complication. Future studies need to document the complications meticulously so that the true risk can be established.

Abstract
Purpose:To compare the clinical outcomes of the Masquelet technique and Ilizarov bone transport method for the treatment of patients with infected bone defects in the lower extremities. Methods: Eligible studies were searched from six databases until 12 April 2021. Data extraction was independently conducted by two investigators, which was followed by a quality assessment. Weighted mean difference (WMD) and 95% confidence interval (CI) were used to analyze continuous variables, while odds ratio (OR) and 95% CI were used to analyze categorical variables. All statistical analyses were conducted using RevMan 5.3 and Stata 12.0. Results: Thirteen articles were included in this meta-analysis. There was a significant difference observed in hospitalization costs (WMD [95% CI] = -1.75 [-2.50, -0.99] thousand US dollar, p < 0.00,001), final union time (WMD [95% CI] = -4.54 [-6.91, -2.17] months, p = 0.0002), time to full weight bearing (WMD [95% CI] = -1.73 [-3.36, -0.10] months, p = 0.04), quality of life (WMD [95% CI] = 7.70 [4.74, 10.67], p < 0.00,001), and the risk of complications (OR [95%CI] = 0.39 [0.19, 0.79], p = 0.009) between the Masquelet and Ilizarov groups. No significant differences in other outcomes were observed between the two groups. Conclusion: Masquelet technique exhibited the advantages in the lower hospitalization cost, shorter final union time, shorter time to full weight bearing, lower rate of complications, and better post-operative quality of life, compared with Ilizarov bone transport method. However, this finding should be confirmed in large-scale clinical samples.

Abstract
Introduction: Reconstruction of complex, open-grade distal femur fracture with bone defect presents an orthopaedic surgeon with a distinctive challenge as they are often associated with contaminated, compromised soft tissue and poor host condition. Conventional techniques like vascularized fibula transfer, autologous bone grafting or distraction osteogenesis focus mainly over bone union without taking infection control into consideration. The aim of this study is to evaluate the outcome of induced membrane technique in the reconstruction of open distal femur fracture with bone defect. Methods: 10 such patients were retrospectively evaluated. Union was considered when a minimum of two cortices were seen on a radiograph. Knee Society Score was used to evaluate the functional outcome. Results: The average length of the defect was 5.7cm (3–10 cm) with mean interval period between the two stages being 42.7 days (34–51 days). Internal fixation was carried out in all cases. In 7 patients we used a mixture of cancellous autograft and cancellous allograft mixed in a ratio of 3:1. In the remaining 3 patients we used only cancellous autograft. Radiological union was achieved in all patients with mean union time of 8.5 months (7–11 months). Mean knee score was 79 (69–86) and mean function score was 71.5 (60–80). Conclusion: The induced membrane technique is an economical, technically less demanding technique for reconstruction of distal femur fracture with bone defects. The results are reproducible with a high success rate and without the need of any special instrumentation. It bestows infection control and prevents graft resorption. Long reconstructive period and donor site morbidity are matters of concern.

Abstract
Extrusion of bone is a rare situation in open fractures due to high energy trauma. There are few studies, reporting successful reimplantation of the extruded bone segment using various sterilization and fixation protocols. However, there are no definitive treatment strategies for this challenging situation. We report a case of 30-year-old male patient with grade IIIB compound right distal femur fracture with an extruded long bone segment, who was treated with successful sterilization and immediate reimplantation of an extruded long diaphyseal segment of distal femur following extensive cleaning with sterile normal saline, removal of debris with scrubbing by sterile brush, soakage in the broad-spectrum antimicrobial solution for 30 min, sterilization by autoclaving at 121°C for 45 min, and reimplantation during stable internal fixation with lateral distal femur locking plate using Arbeitsgemeinschaft für Osteosynthesefragen techniques. At 3 months, iliac crest bone grafting, osteoperiosteal flaps, and augmented fixation with a medial locking plate were performed through a subvastus approach for a void in the medial supracondylar femur region. Intraoperatively, punctate bleeding was observed from the reimplanted fragment. Infection was ruled out with normal leukocyte count, C-reactive protein marker, no evidence of unhealthy granulation tissue, and a sterile culture report from the fracture site. The fracture healed in 12 months and the patient had good functional outcome with a lower extremity functional score of 80% and knee range of motion of 110° at short-term follow up of 2 years without any complication. Decision of reimplantation is individualized depending on the time of presentation, contamination, and comminution of extruded fragment with scarce literature on standard treatment strategies. In our case, early presentation, meticulous debridement, unique sterilization technique, immediate reimplantation, and augmented dual distal femur plating with bone grafting aided in achieving successful union with good functional outcome and knee range of motion, avoiding any complications.

Abstract
BACKGROUND Open fractures are a difficult entity, often complicated by infection and nonunion. Bone loss in such fractures adds to the complexity. Conventional techniques of bone defect management are mainly directed toward fracture union but not against preventing infection or joint stiffness. In this case series, we evaluated Masquelet's technique for management of open fractures with bone loss. MATERIALS AND METHODS Twenty seven open fractures with bone defect, which presented within 3 days of trauma were planned for treatment by Masquelet's technique. Followup ranged from 21 to 60 months. RESULTS Average length of bone defect was 6 cm. Radiological union was obtained at a mean of 280 days since first stage of surgery. Time for union was not related to the size of defect. Union was faster in metaphyseal region (265.6 ± 38.8 days) as compared to diaphysis (300.9 ± 58.6 days). No patient had residual infection after stage 1. All the patients were able to mobilize with full weight bearing after radiological union with a satisfactory range of motion of adjacent joints. CONCLUSION This technique can be routinely applied in compound fractures with bone loss with good results. Chances of infection are reduced using antibiotic cement spacer as an adjunct to thorough debridement. Induced biomembrane revascularizes the graft. Union can be expected in most of the cases, however, long time to union is a limitation. Technique is cost-effective and does not require special training or instrumentation. Although it is a two-stage surgery, requirement of multiple surgeries, as may be needed in conventional methods, is avoided.

Abstract
The 2015–2020 Dietary Guidelines for Americans advocate for increasing fruit intake and replacing energy-dense foods with those that are nutrient-dense. Nutrition across the lifespan is pivotal for the healthy development and maintenance of bone. The National Osteoporosis Foundation estimates that over half of Americans age 50+ have either osteoporosis or low bone mass. Dried plums, also commonly referred to as prunes, have a unique nutrient and dietary bioactive profile and are suggested to exert beneficial effects on bone. To further elucidate and summarize the potential mechanisms and effects of dried plums on bone health, a comprehensive review of the scientific literature was conducted. The PubMed database was searched through 24 January 2017 for all cell, animal, population and clinical studies that examined the effects of dried plums and/or extracts of the former on markers of bone health. Twenty-four studies were included in the review and summarized in table form. The beneficial effects of dried plums on bone health may be in part due to the variety of phenolics present in the fruit. Animal and cell studies suggest that dried plums and/or their extracts enhance bone formation and inhibit bone resorption through their actions on cell signaling pathways that influence osteoblast and osteoclast differentiation. These studies are consistent with clinical studies that show that dried plums may exert beneficial effects on bone mineral density (BMD). Long-term prospective cohort studies using fractures and BMD as primary endpoints are needed to confirm the effects of smaller clinical, animal and mechanistic studies. Clinical and prospective cohort studies in men are also needed, since they represent roughly 29% of fractures, and likewise, diverse race and ethnic groups. No adverse effects were noted among any of the studies included in this comprehensive review. While the data are not completely consistent, this review suggests that postmenopausal women may safely consume dried plums as part of their fruit intake recommendations given their potential to have protective effects on bone loss.

Abstract
OBJECTIVE This study aimed to evaluate the outcome of using a metaphyseal locking plate as a definitive external fixator for treating open tibial fractures based on biomechanical experiments and analysis of clinical results. METHODS A metaphyseal locking plate was used as an external fixator in 54 open tibial fractures in 52 patients. The mean follow-up was 38 months (range, 20-52 months). Moreover, static axial compression and torsional tests were performed to evaluate the strength of the fixation techniques. RESULTS The average fracture healing time was 34.5 weeks (range, 12-78 weeks). At 4 weeks postoperatively and at the final follow-up, the average Hospital for Special Surgery knee score was 85 (range, 81-100) and 94 (range, 88-100), respectively, and the American Orthopaedic Foot and Ankle Society score was 88 (range, 80-100) and 96 (range, 90-100), respectively. Based on the static test result, the axial stiffness was significantly different among groups (p=0.002), whereas the torsional stiffness showed no significant difference (p=0.068). CONCLUSIONS Clinical outcomes show that the use of locking plate as a definitive external fixator is an alternative choice for tibial fractures after obtaining appropriate fracture reduction. However, external locked plating constructs were not as strong as standard locked plating constructs. Therefore, the use of external locked plating constructs as a definitive treatment warrants further biomechanical study for construct strength improvement.

Abstract
BACKGROUND Treatment of congenital femoral deficiency is a complex, multistage protocol and a variety of strategies have been devised to address joint instability, limb length inequality, and deformities. Despite being an important part of the algorithmic approach to the overall treatment of patients with congenital femoral deficiency, a reproducible, safe, and functional treatment for femoral length discrepancy in patients with mild and moderate congenital femoral deficiency has not been reported. QUESTIONS/PURPOSES (1) Does femoral lengthening by means of distraction osteogenesis, using a monolateral external fixator, result in effective lengthening without loss of hip or knee range of motion? (2) Does femoral lengthening cause an inhibition of femoral growth in patients with congenital femoral deficiency? (3) Do patients/families report satisfactory functional and emotional outcomes after undergoing femoral lengthening? (4) What proportion of patients develops complications after femoral lengthening with this technique? METHODS Between 2005 and 2009, we evaluated 38 patients for femoral length discrepancy secondary to unilateral congenital femoral deficiency. Thirty-two patients completed treatment with distraction osteogenesis using a monolateral external fixator; general indications for this approach were congenital femoral deficiency Paley Types 1a, 1b, or 2a that had not previously undergone lengthening and had stable hip and knee joints. Of the 32 patients that completed treatment, 30 (94%) were available at a minimum of 2 years (mean, 3 years; range, 2-4.5 years) and were evaluated in this retrospective study. Preoperative and postoperative radiographic analysis, physiotherapy data, patient-based outcomes scores, and complications were reviewed for all eligible patients. Growth inhibition was measured using serial radiographs over the 2-year followup with the unaffected limb considered the norm. Functional and emotional outcomes were reported by adolescent patients or parents of younger children using the Pediatric Orthopaedic Society of North America Pediatric Outcomes Data Collection Instruments (PODCI), a validated patient-based outcomes measure. RESULTS The mean distal femoral lengthening was 6 cm (SD ± 2 cm; range, 1.6-9 cm), for a mean percent of femoral length discrepancy correction of 112% (SD ± 55%; range, 15%-215%). Comparison of patient preoperative with postoperative mean hip and knee flexion and extension showed no difference with the numbers available (hip flexion: p = 0.219, mean difference of -5, 95% confidence interval [CI], 10, SD = 20; hip extension: p = 0.423, mean difference of -1, 95% CI, 2, SD = 5; knee flexion: mean difference of -7°, SD ± 29°, CI, 15, p = 0.467; knee extension: mean difference of -1°, SD ± 9°, CI, 4, p = 0.757). A comparison of the mean preoperative inhibition of 41% (range, -38% to 300%; SD ± 72; 95% CI, 29%) with the mean postoperative inhibition of 16% (range, -242% to 100%; SD ± 61%; 95% CI, 25%) for a mean postoperative stimulation of 25% (p = 0.055, SD ± 90%; 95% CI, 36%). In all six PODCI categories surveyed, patients had favorable standardized and normative scores, but patients who underwent femoral lengthening greater than 6 cm had both lower global functioning scores (90, SD ± 10 versus 96, SD ± 3, p = 0.043) and worse pain/comfort scores (79, SD ± 25 versus 96, SD ± 7, p = 0.029), and patients who had mean percent femoral lengthening greater than 25% of initial femur length had worse pain/comfort scores (79, SD ± 23 versus 97, SD ± 4, p = 0.012) with similar global functioning scores (90, SD ± 9 versus 96, SD ± 3, p = 0.058). The total number of postsurgical complications was 30 in 60 planned surgical procedures (50%). CONCLUSIONS Our study results support the use of the described surgical technique for femoral lengthening in treating patients with congenital femoral deficiency. Additional studies are needed both to follow long-term patient-reported outcome measures, especially after a second or third lengthening, and to determine the effect of serial lengthening on the stimulation or inhibition of growth and rate of complications. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
We carried out a systematic review of the literature to evaluate the evidence regarding the clinical results of the Ilizarov method in the treatment of long bone defects of the lower limbs. Only 37 reports (three non-randomised comparative studies, one prospective study and 33 case-series) met our inclusion criteria. Although several studies were unsatisfactory in terms of statistical heterogeneity, our analysis appears to show that the Ilizarov method of distraction osteogenesis significantly reduced the risk of deep infection in infected osseous lesions (risk ratio 0.14 (95% confidence interval (CI) 0.10 to 0.20), p < 0.001). However, there was a rate of re-fracture of 5% (95% CI 3 to 7), with a rate of neurovascular complications of 2.2% (95% CI 0.3 to 4) and an amputation rate of 2.9% (95% CI 1.4 to 4.4).The data was generally not statistically heterogeneous. Where tibial defects were > 8 cm, the risk of re-fracture increased (odds ratio 3.7 (95% CI 1.1 to 12.5), p = 0.036). The technique is demanding for patients, illustrated by the voluntary amputation rate of 1.6% (95% CI 0 to 3.1), which underlines the need for careful patient selection.

Abstract
Limb length discrepancy (LLD) and other patient factors are thought to influence the complication rate in (paediatric) limb deformity correction. In the literature, information is conflicting. This study was performed to identify clinical factors that affect the complication rate in paediatric lower-limb lengthening. A consecutive group of 37 children was analysed. The median proportionate LLD was 15 (4-42)%. An analysis was carried out on several patient factors that may complicate the treatment or end result using logistic regression in a polytomous logistic regression model. The factors analysed were proportionate LLD, cause of deformity, location of corrected bone, and the classification of the deformity according to an overall classification that includes the LLD and all concomitant deformity factors. The median age at the start of the treatment was 11 (6-17) years. The median lengthening index was 1.5 (0.8-3.8) months per centimetre lengthening. The obstacle and complication rate was 69% per lengthened bone. Proportionate LLD was the only statistically significant predictor for the occurrence of complications. Concomitant deformities did not influence the complication rate. From these data we constructed a simple graph that shows the relationship between proportionate LLD and risk for complications. This study shows that only relative LLD is a predictor of the risk for complications. The additional value of this analysis is the production of a simple graph. Construction of this graph using data of a patient group (for example, your own) may allow a more realistic comparison with results in the literature than has been possible before.
