RESUMEN
The tibia is the most common long bone at risk for nonunion with an annual incidence ranging from 12% to 19%. This topic continues to be an area of research as management techniques constantly evolve. A foundational knowledge of the fundamental concepts, etiology, and risk factors for nonunions is crucial for success. Treatment of tibial shaft nonunions often requires a multidisciplinary effort. This article provides guidance based on the most recent literature that can be used to aid the treating provider in the diagnosis, workup, and management of tibial shaft nonunions.

BACKGROUND: The failure of bone fracture healing is one of the major complications of fracture treatment, especially of the tibia due to its limited soft tissue coverage and high rate of open injuries. Although implant development is constantly progressing and modern surgical techniques are continuously improving, infected tibial nonunion plays a decisive role in terms of its variable clinical presentation. OBJECTIVE: This article provides guidelines for the successful surgical treatment of infected tibial nonunion. MATERIAL AND METHOD: Strategies are presented to identify infection as a cause of failure of fracture healing and to achieve infection and bone healing. RESULTS: A significant amount of tibial nonunions primarily thought to be aseptic ultimately turn out to be infected nonunions. CONCLUSION: The treatment of infected tibial nonunion requires extensive clinical, radiological and laboratory diagnostics as well as a profound biomechanical and biological understanding of the bone situation. This is the only way to achieve rapid osseous healing with as few revision interventions as possible.

OBJECTIVE: To analyze leg length discrepancy and overgrowth after tibial shaft fractures in children. MATERIAL AND METHODS: We analyzed medical records of 103 patients younger 14 years old with tibial shaft fractures between January 2003 and November 2018. Treatment included plastering and insertion of titanium elastic nail. To identify the risk factors of leg length discrepancy ≥1 cm and overgrowth ≥1 cm, we performed logistic regression analysis. Statistical analysis was carried out using the SPSS software for Windows. RESULTS: Gender (p=0.014) and treatment methods (p=0.011) are the most significant predictors of leg length discrepancy and overgrowth. In boys, the risk of leg length discrepancy ≥1 cm was 7.4 times higher than in girls. The risk of leg length discrepancy ≥1 cm was 4.3 times higher after insertion of titanium elastic nail compared to plastering. The risk of overgrowth ≥1 cm was 5.4 times higher in boys than in girls. The risk of overgrowth ≥1 cm was 4.7 times higher after insertion of titanium elastic nail compared to plastering. CONCLUSION: One should consider the risk of leg length discrepancy and overgrowth in children with tibial shaft fractures. This is especially true for boys undergoing insertion of titanium elastic nail.

Introduction: Understanding of displaced anterior tibial spine fractures has evolved over the years and is now considered to be anterior cruciate ligament avulsion injuries rather than intra-articular fractures. However, there are very few studies available evaluating the presence or absence of a pivot shift test, which is specific in diagnosing anterior cruciate ligament insufficiency, in patients with anterior tibial spine fractures. This study aimed to find out the prevalence of the positive pivot shift test among patients with displaced anterior tibial spine fractures undergoing arthroscopic fixation in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among patients presented with displaced anterior tibial spine fractures undergoing arthroscopic fixation. The data were collected between 1 January 2020 and 30 May 2022. Ethical approval was obtained from the Institutional Review Committee (Reference number: IRC_2019_11_09_1). All patients who presented with displaced anterior tibial spine fractures undergoing arthroscopic fixation were included in the study and those who did not provide consent were excluded. The pivot test was performed under anaesthesia. Point estimate and 90% Confidence Interval were calculated. Results: Among 48 patients, pivot shift was positive in 36 (75%) (64.75-85.25, 90% Confidence Interval). The mean age of the participants was 28.97±11.16 years, 21 (58.33%) were males and 15 (41.66%) were females. Conclusions: The prevalence of positive pivot shift test under anaesthesia in patients with displaced anterior tibial spine fractures undergoing arthroscopic fixation was higher than other studies done in similar settings. Keywords: anterior cruciate ligament; arthroscopy; knee fractures; physical examination.

OBJECTIVE: Floating knee type IIC, according to Fraser's classification, is an uncommon severe injury that typically occurs in polytrauma. In such cases, intra-articular fracture and the high degree of comminution and deformity of the mid-distal femur make fixation challenging. The purpose of this study was to demonstrate that minimally invasive plate osteosynthesis (MIPO) technology can simplify these complex problems and improve patient prognosis. CASE PRESENTATION: A 38-year-old man injured his left leg in a car accident, causing pain, swelling, deformity, and limited mobility on his left knee and thigh, and two small open wounds were noted mainly of the anterior aspect of the mid-distal thigh. Physical examination and computed tomography angiography of the lower limb confirmed that there was no damage to the neurovascular system. The clinical diagnosis was closed intra-articular fracture of the proximal tibia, open intra-articular fracture of the distal femur with extension to the diaphysis, and a patellar fracture on the ipsilateral knee. The treatment strategy involved a locking plate system applying MIPO technology. Postoperative evaluation of the patient was satisfactory, with immediate functional exercise, full weight-bearing after three months, and return to daily activity without pain. Final follow-up taken 3 years after surgery showed good lower limb alignment and complete plasticity of the bone structure, by which time the patient showed good limb function. CONCLUSIONS: Minimally invasive techniques can provide a simple and effective treatment for some complex fractures.

OBJECTIVE: To determine the outcomes of pilon and tibial shaft fractures with syndesmotic injuries compared with similar fractures without syndesmotic injury. DESIGN: Retrospective case-control study. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: All patients over a 5-year period (2012-2017) with tibial shaft or pilon fractures with a concomitant syndesmotic injury and a control group without a syndesmotic injury matched for age, OTA/AO fracture classification, and Gustilo-Anderson open fracture classification. INTERVENTION: Preoperative or intraoperative diagnosis of syndesmotic injury with reduction and fixation of both fracture and syndesmosis. MAIN OUTCOME MEASUREMENT: Rates of deep infection, nonunion, unplanned reoperation, and amputation in patients with a combined syndesmotic injury and tibial shaft or pilon fracture versus those without a syndesmotic injury. RESULTS: A total of 30 patients, including 15 tibial shaft and 15 pilon fractures, were found to have associated syndesmotic injuries. The matched control group comprised 60 patients. The incidence of syndesmotic injury in all tibial shaft fractures was 2.3% and in all pilon fractures was 3.4%. The syndesmotic injury group had more neurologic injuries (23.3% vs. 8.3% P = 0.02), more vascular injuries not requiring repair (30% vs. 15%, P = 0.13), and a higher rate compartment syndrome (6.7% vs. 0%, P = 0.063). Segmental fibula fracture was significantly more common in patients with a syndesmotic injury (36.7% vs. 13.3%, P = 0.04). Fifty percent of the syndesmotic injury group underwent an unplanned reoperation with significantly more unplanned reoperations (50% vs. 27.5%, P = 0.04). The syndesmotic group had a significantly higher deep infection rate (26.7% vs. 8.3% P = 0.047) and higher rate of amputation (26.7% vs. 3.3% P = 0.002) while the nonunion rate was similar (17.4% vs. 16.7% P = 0.85). CONCLUSIONS: Although syndesmotic injuries with tibial shaft or pilon fractures are rare, they are a marker of a potentially limb-threatening injury. Limbs with this combined injury are at increased risk of deep infection, unplanned reoperation, and amputation. The presence of a segmental fibula fracture should raise clinical suspicion to evaluate for syndesmotic injury. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

OBJECTIVE: To explore a new artificial intelligence (AI)-aided method to assist the clinical diagnosis of tibial plateau fractures (TPFs) and further measure its validity and feasibility. METHODS: A total of 542 X-rays of TPFs were collected as a reference database. An AI algorithm (RetinaNet) was trained to analyze and detect TPF on the X-rays. The ability of the AI algorithm was determined by indexes such as detection accuracy and time taken for analysis. The algorithm performance was also compared with orthopedic physicians. RESULTS: The AI algorithm showed a detection accuracy of 0.91 for the identification of TPF, which was similar to the performance of orthopedic physicians (0.92±0.03). The average time spent for analysis of the AI was 0.56 s, which was 16 times faster than human performance (8.44±3.26 s). CONCLUSION: The AI algorithm is a valid and efficient method for the clinical diagnosis of TPF. It can be a useful assistant for orthopedic physicians, which largely promotes clinical workflow and further guarantees the health and security of patients.

OBJECTIVE: To explore the correlation between the fracture line inferior plane and perioperative deep venous thrombosis (DVT) in patients with tibial fractures. METHODS: Data was collected from the medical records of 536 consecutive patients with tibial fractures at Xi'an Honghui Hospital. The patients were divided into distal, shaft, and proximal segment groups according to the fracture line inferior plane on radiographs. Multivariate logistic regression models were used to identify the role of the inferior plane of the fracture line in perioperative DVT. RESULTS: A total of 431 patients were included in the study and 226 patients had perioperative DVT in the lower extremities, including 11 proximal and 215 distal DVTs. Univariate regression analysis showed a significant correlation between the proximal segment and perioperative DVT; however, no correlation was found in the shaft segment group. Additionally, age, coronary heart disease, associated injuries, and time to operation ≥6 days were risk factors for perioperative DVT. However, fixation with intramedullary nails may be a protective factor for perioperative DVT compared with plates. After adjusting for potential confounding factors, the proximal segment group had an increased incidence of perioperative DVT compared to the distal segment group. CONCLUSIONS: The proximal segment may be correlated with an increased incidence of perioperative DVT by 7.30-fold in patients with tibial fractures compared to that in the distal segment. In clinical practice, surgeons should be vigilant for DVT formation in these patients.

RESUMEN Las fracturas expuestas de tibia han sido uno de los problemas más importantes para los sistemas de atención en salud pública. Se caracterizan por tres factores de riesgo fundamentales: daño óseo y tejidos blandos, gran posibilidad de contaminación y dificultades para el tratamiento conservador y quirúrgico, debido al daño óseo y de partes blandas asociados, que implica un alto índice de complicaciones. El tratamiento de estas fracturas es un tema ampliamente discutido en cuanto a la técnica quirúrgica a utilizar. Debido la pobre vascularización y poca cantidad de tejidos blandos que cubren la tibia, este hueso es muy vulnerable a la pseudoartrosis y a la infección. El objetivo de este trabajo fue describir la técnica quirúrgica de transportación ósea con fijador externo Ilizarov y evaluar el resultado en defectos óseos de tibia de más de 6 cm, secundario a pseudoartrosis infectada. Como resultado, el paciente evolucionó con una pseudoartrosis séptica de tibia derecha secundaria a fractura expuesta. El seguimiento fue de 18 meses, la pérdida ósea de 6 cm, la velocidad de distracción de 1 mm/día, el período de transportación de 95 días, y el tiempo con fijador de 198 días. Fue necesario realizar un nuevo proceder quirúrgico en el sitio de contacto, con vistas a reavivar los extremos óseos. La transportación ósea con fijador Ilizarov es válida para el tratamiento de la pérdida ósea en fracturas expuestas de tibia o pseudoartrosis séptica (AU).
ABSTRACT Exposed tibia fractures have been one of the most important problems for public health care systems. They are characterized by three main risk factors: bone and soft tissue damage, high possibilities of contamination and difficulties for the surgical and conservative treatment, due to the associated bone and soft tissues damage implying a high rate of complications. The treatment of these fractures is a widely discussed topic regarding the surgical technique to be used. Due to poor vascularization and little quantity of soft tissue covering tibia, this bone is highly vulnerable to pseudoarthritis and infection. The aim of this work was to describe the surgical technique of bone transport with Ilizarov external fixator and to evaluate the result in tibial bone defects of more than 6 cm, secondary to infected pseudoarthritis. As a result, the patient evolved with septic pseudoarthritis of right tibia secondary to exposed fracture. The follow up lasted 18 months; the bone loss was 6 cm; the distraction speed was 1 mm/day; the transportation period was 95 days and the time with fixator was 198 days. It was necessary to perform a new surgical procedure at the contact site to recuperate the bone ends. Bone transport with Ilizarov fixator is valid for the bone loss treatment in tibia exposed fractures or septic pseudo arthritis (AU).

Periprosthetic fracture occurring during or after total knee arthroplasty is a rare injury. Literature concerning periprosthetic tibial factures is sparse, and there is limited guidance for evidence-based management. This review aims to provide readers with an overview of the epidemiology, risk factors, and classification of these fractures. Management includes nonoperative treatment of nondisplaced fractures, fixation for those with stable implants, and revision for those with loose implants.

RESUMEN Con el paulatino incremento de accidentes automovilísticos, de trabajo, y la violencia urbana, las fracturas expuestas y complejas constituyen traumatismos de creciente incidencia y de difícil solución, con largos períodos de convalecencia que ponen en peligro la vida o la conservación del miembro lesionado. Un gran número de ellas dejan secuelas invalidantes. Existen varios tratamientos, entre ellos la fijación externa, utilizando el sistema creado por el profesor Rodrigo Álvarez Cambras, con varias ventajas que proporcionan una mejor evolución. Se realizó este trabajo con el objetivo de mostrar la evolución y los resultados de un paciente ingresado y operado con el diagnóstico de lesión expuesta, compleja y grave de la extremidad inferior, específicamente de tibia. Este presentó varias complicaciones, por lo que se le colocó un aparato de osteosíntesis de fijación externa Álvarez Cambras en el Hospital Provincial Clínico Quirúrgico Docente José Ramón López Tabrane, de Matanzas (AU).
ABSTRACT With the gradual increase of automobile and work accidents as well as urban violence, exposed and complex fractures are traumas of increasing incidence and difficult solution, with long periods of convalescence that endanger the life or the conservation of the injured member. A large number of them leave invalidating sequels. There are several treatments, including external fixation using the system created by Professor Rodrigo Alvarez Cambra, with several advantages that provide a better evolution. The current work was carried out with the objective of showing the evolution and results of a patient who entered the Teaching Provincial Clinical-surgical Hospital Jose Ramon Lopez Tabrane, of Matanzas, and underwent a surgery with the diagnosis of exposed, complex and serious lesion in the lower limb, specifically of tibia. The patient had several complications and so he was put an Alvarez Cambra external fixation osteosynthesis devise (AU).

INTRODUCTION: Tibial shaft fractures are common injuries in the adolescent age group. Potential complications from the injury or treatment include infection, implant migration, neurovascular injury, compartment syndrome, malunion, or nonunion. METHODS: Published literature was reviewed to identify studies which describe the management options, complications, and outcome of tibial shaft fractures in adolescents. RESULTS: Acceptable alignment parameters for tibial shaft fractures have been defined. Operative indications include open fractures and other severe soft tissue injuries, vascular injury, compartment syndrome, ipsilateral femoral fractures, and polytrauma. Relative indications for operative treatment are patient/family preference or morbid obesity. Closed reduction and cast immobilization necessitates radiographic observation for loss of reduction over the first 3 weeks. Cast change/wedging or conversion to operative management may be required in 25% to 40%. Flexible nailing provides relative fracture stability while avoiding the proximal tibial physis, but the fracture will still benefit from postoperative immobilization. Rigid nailing provides greater fracture stability and allows early weight bearing but violates the proximal tibial physis. Plate and screw osteosynthesis provide stable anatomic reduction, but there are concerns with delayed union and wound complications related to the dissection. External fixation is an excellent strategy for tibia fractures associated with complex wounds but also requires observation for loss of reduction. DISCUSSION AND CONCLUSIONS: The majority of adolescent tibia shaft fractures can be successfully managed with closed reduction and cast immobilization. Unstable fractures that have failed cast treatment should be treated operatively. Flexible intramedullary nailing, rigid intramedullary nailing, plate and screw osteosynthesis, and external fixation are acceptable treatment options that may be considered for an individual patient depending upon the clinical scenario.

Complex tibial plateau fractures in elderly patients exhibiting severe osteoporosis and articular surface collapse are challenging. Decision-making is difficult when the posterior column is involved. Open reduction and internal fixation of complex tibial plateau fractures in patients with severe osteoporosis are prone to failure. In this paper, we describe a new method for the maintenance of the articular surface of complex tibial plateau fractures in elderly patients. An anterior horizontal rafting plate (3.5-mm-thick reconstruction and locking plate [Zimmer Inc., Warsaw, IN, USA]) is placed via conventional posteromedial and anterolateral incisions. The plate is inserted between the anterior bony surface of the proximal tibia and the subpatellar fat pad; plate positioning is checked under direct vision. The patient is encouraged to begin functional recovery soon after operation. Progressive weight-bearing begins at 10 weeks postoperatively and is gradually increased during fracture healing. Clinical follow-up was performed at 4, 8, and 12 weeks, 6 and 12 months, and yearly thereafter. No articular collapse or fragment displacement was evident on three-dimensional computed tomography performed 6 months after surgery. The knee range of motion was 5-130º at the last follow-up (4 years after surgery). This technique may be a good option for treating complex tibial plateau fractures, especially in elderly patients with severe osteoporosis.

Introducción: Las fracturas diafisiarias de la tibia son las que con mayor frecuencia encuentran los cirujanos ortopédicos en su práctica habitual. La fractura expuesta de tibia es una urgencia quirúrgica que requiere desbridamiento, lavado, reducción y estabilización de los fragmentos óseos lo antes posible, e inicio de la administración de antibióticos profilácticos. Objetivo: Caracterizar los pacientes con fractura expuesta de tibia grado II y IIIA, tratados mediante estabilización con clavo acerrojado intramedular, identificando mecanismo de producción, número de intervenciones quirúrgicas por paciente, así como las principales complicaciones encontradas. Método: Estudio observacional, descriptivo, ambispectivo y de corte transversal en pacientes con fractura abierta de tibia, tratados quirúrgicamente con clavo acerrojado intramedular. Resultados: La edad de los pacientes osciló entre 21 y 69 años. Predominó el sexo masculino (65,4 porciento), la mayor causa traumática fueron los accidentes en la vía pública (37 pacientes); predominaron las fracturas del tercio medio abiertas grado IIIA con estadía hospitalaria menor de 10 días, y complicaciones en la tercera parte de los pacientes. Conclusiones: Se observó mayor incidencia en pacientes masculinos en edades comprendidas entre 18 y 29 años por accidentes del tránsito. La localización habitual fue el tercio medio y más de la mitad fueron clasificadas como grado IIIA de la tipología de Gustilo y Anderson(AU)
Introduction: Diaphyseal fractures of the tibia are those most frequently treated by orthopedic surgeons in their common practice. The exposed fracture of the tibia is a surgical emergency that requires debridement, lavage, reduction and stabilization of the bone fragments as soon as possible, and initiation of the administration of prophylactic antibiotics. Objective: To characterize patients with grade II and IIIA exposed tibial fracture, treated by stabilization with an intramedullary nail, identifying production mechanism, number of surgical interventions per patient, as well as the main complications found. Method: An observational, descriptive, ambispective and cross-sectional study in patients with an open fracture of the tibia treated surgically with an intramedullary locking nail. Results: The age of the patients ranged between 21 and 69 years. Male sex predominated (65.4 percent), the major traumatic cause was accidents on public roads (37 patients); Grade IIIA open middle third fractures predominated with hospital stays of less than 10 days, and complications in a third of the patients. Conclusions: High incidence was observed in male patients between the ages of 18 and 29 due to traffic accidents. The usual location was the middle third and more than half were classified as grade IIIA of Gustilo and Anderson typology(AU)

We report a further case of spondylometaphyseal dysplasia - corner fracture type due to the fibronectin-1 gene (SMD-FN1) in a child originally thought to have metaphyseal chondrodysplasia-Brussels type (MCD Brussels). We highlight phenotypic differences with the SMD-FN1 published reports. This case is unique in terms of the method of molecular confirmation. Findings from the 100 000 Genomes Project were originally negative (in both tier 1 and 2); however, subsequent reanalysis, initiated by an automated search for new gene-disease associations in PanelApp, highlighted a candidate diagnostic variant. Our child had short stature, facial dysmorphism, spondylometaphyseal dysplasia and corner fractures and a heterozygous de novo missense variant in FN1 (c.675C>G p.(Cys225Trp), which was likely pathogenic. The variant matched the clinical and radiological features and a diagnosis of SMD-FN1 was confirmed. We explore the diagnostic journey of this patient, compare her findings with the previous 15 patients reported with SMD-FN1 and discuss the diagnostic utility of automated reanalysis. We consider differences and similarities between MCD Brussels and SMD-FN1, by reviewing literature on both conditions and assess whether they are in fact the same disorder.

OBJECTIVES: To validate and make evidence based changes to the Israel Defense Forces medial tibial stress fracture diagnosis and treatment protocol. DESIGN: Prospective cohort study. METHODS: 429 Elite infantry recruits were reviewed for signs and symptoms of medial tibial stress fracture during 14 weeks of basic training. Suspicion of medial tibial stress fracture was based on the presence of pain, tenderness <1/3 the length of the tibia and a positive fulcrum and/or hop test. Recruits with suspected medial tibial stress fractures were initially treated with 10-14 days of rest. Bone scan was performed only when recruits failed to respond to the rest regimen or required immediate diagnosis. RESULTS: 31 Out of 49 recruits with a suspicion of medial tibial stress fracture underwent bone scan, including 8/26 recruits whose symptoms did not resolve after being treated clinically as stress fractures. There was a significantly greater incidence of medial tibial stress fractures when a positive hop test was present in addition to tibial pain and tenderness (p=0.0001), odds ratio 52.04 (95% CL, 2.80-967.74). Medial tibial stress fracture was found to occur when the band of tibial tenderness was ≤10cm in length. Tibial pain scores were not predictive of stress fracture. CONCLUSIONS: This validation study provides the clinician with evidence based guidelines for the clinical diagnosis and treatment of medial stress fractures and their differentiation from shin splints. An initial treatment protocol without the use of imaging was found to be effective in more than two-thirds of the cases.

Intraoperative fractures are a rare complication in total knee arthroplasty. Limited literature exists in regard to the incidence, mechanism of injury and management of intraoperative fractures. The authors report a unique case of an 80-year-old man who sustained a medial tibial plateau fracture that occurred intraoperatively during final tibia bone preparation with the use of the Woolley Tibia Punch (Innomed, Savannah, Georgia, USA). The fracture was managed with the addition of 4.5 mm cortical lag screws and the addition of a stemmed tibial implant to bypass the fracture. This is the first reported case in literature that describes an intraoperative medial tibial plateau that occurred through the use of a Woolley Tibia Punch. The authors recommend the consideration of drilling to prepare sclerotic bone for cement penetration rather than a punch in order to minimise the potential for intraoperative fractures that may occur with the use of a punch.

In patients with ankle fractures, the presence of a posterior malleolar fracture has a negative impact on the prognosis. Computed tomography (CT) scanning is essential for fracture classification and treatment planning, as the indication for surgery depends on the 3-dimensional fragment outline and displacement, incisura involvement, and the presence of joint impaction. Anatomic reduction of a posterior malleolar fragment restores the incisura, facilitating reduction of the distal part of the fibula, and it also restores the integrity of the posterior portion of the syndesmosis, reducing the need for additional syndesmotic stabilization. Direct open reduction and fixation of posterior malleolar fragments from a posterior orientation is biomechanically more stable and provides a more accurate reduction than does indirect reduction and anterior-to-posterior screw fixation. Intra-articular step-off of >=2 mm is an independent risk factor for an inferior outcome and the development of posttraumatic arthritis, irrespective of the fragment size.

OBJECTIVES: This study aims to describe the important points for treatment of aseptic tibial oligotrophic and atrophic nonunions by intramedullary nailing (IMN). PATIENTS AND METHODS: The retrospective study included 17 biologically nonactive nonunion patients (12 males, 5 females; mean age 36.4 years; range, 19 to 49 years) operated between February 2010 and November 2017 by deformity correction, static IMN and autografting. The mean follow-up time was 4.2 (range, 3 to 7) years. The initial fracture management was external fixator for all patients. Fourteen patients had open fractures initially. Six patients had valgus, four patients had varus, three patients had oblique plane, and four patients had external rotational deformity. Nonunion diagnosis was established on the basis of the patient history and physical examination based on plain radiographs, computed tomography or both. All patients were evaluated by the same protocol to exclude any infection. RESULTS: The median time from injury to nailing was mean 10.3 (range, 6.1 to 36.5) months. Radiologic and clinical union was achieved in all patients. The mean union time was 3.64 (range, 3 to 6) months. Three patients had positive intraoperative bacteriological culture. In four patients, dynamization was necessary for consolidation. Late deep infection developed in three patients after union, and all infected cases were operated by implant removal, debridement, and appropriate antibiotics. CONCLUSION: Intramedullary nailing and autografting after external fixator provide good results for the treatment of aseptic biologically nonactive nonunions with deformity. Reamed IMN ensures sufficient deformity correction, biological environment, and mechanical stability. The infection risk should always be kept in mind and patients should be followed-up closely to prevent complications.
