Abstract
This study evaluated the outcomes of chronic Monteggia fractures (CMFs) treated by ulnar osteotomy and monolateral external fixator (MEF), and compare the outcome of gradual versus acute radial head reduction. Two groups of patients were identified. Group 1: gradual reduction of the radial head ( n = 13); group 2: acute reduction ( n = 6). Clinical outcome was evaluated by Kim Elbow Score, whereas radiographic outcome was assessed on plain radiographs. The effect of age, side, time from initial trauma to surgery, rate of unplanned surgery, amount of angulation and lengthening, and final outcome were evaluated. Univariate analysis was performed to identify factors associated with good radiographic outcome. Thirteen patients underwent gradual correction of the ulna. The mean duration of correction was 43.4 days (range, 21-82); the mean angulation and lengthening of the ulna were 22.8° (range, 0°-35°) and 22.2 mm (range, 12.2-40.9), respectively. Six patients underwent acute reduction intraoperatively, the mean angulation and lengthening of the ulna were 17.2° (range, 4°-33.9°) and 5.2 mm (range, 2.5-12.2), respectively. CMF treated by ulnar osteotomy and gradual distraction had better radiological outcome (Group 1; 92.3% 12/13) than those treated by acute reduction of the radial head (Group 2; 3/6, 50%) ( P = 0.071). Reoperation rate was found to be significantly correlated with a fair or poor radiographic results ( P = 0.016). Good clinical and radiological outcomes should be expected in CMF patients treated by gradual lengthening and angulation of the ulna with a MEF.

Abstract
Background In chronic radial head dislocation cases, the radial head may enlarge and become dome-shaped. To date, there is no validated tool to quantify radial head deformation and predict its influence on surgical outcomes. This study assesses the potential value of volume and surface calculations obtained by quantitative three-dimensional computed tomography scanning (Q3DCT) in the workup for a corrective surgery in pediatric patients with missed Monteggia lesions. Material and methods Ten consecutive pediatric patients with a missed Monteggia lesion were included (2012-2020). The volume and articular surface size of the radial head were calculated using Q3DCT, and a three-dimensional reconstruction of the articular surface relief was depicted in a heat map. The head-neck ratio was calculated and compared to Q3DCT data of missed Monteggia patients and their age-/sex-matched controls. Results The radial head volume and radial articular surface size did not differ significantly between patients with missed Monteggia lesions and age-/sex-matched controls (volume 1487 mm3 vs. 1163 mm3, P = .32; articular surface size 282 mm3 vs. 236 mm3, P = .33). Optically, heat maps of the articular surface of missed Monteggia patients did not differ notably from control heat maps. A higher head-neck ratio correlated to a larger radial head volume (Pearson r = 0.73; P = .2). Discussion and conclusion Q3DCT may be an interesting tool in the preoperative workup of pediatric missed Monteggia lesions. Prospective research with larger cohort sizes and data that compares the affected side to the contralateral elbow is needed to assess its true clinical potential.

Abstract
Missed Monteggia fractures in children may cause pain, deformity, decreased range of motion, neurological symptoms, and late arthritis of the elbow. Numerous surgical techniques have been advocated to reconstruct missed Monteggia lesions. The purpose of the present study were first to evaluate the clinical and radiographic outcomes after open reduction of the radial head and corrective osteotomy of the ulna, second to identify the factors associated with the preoperative radial notch/head appearance and the postoperative radiographic results. This study investigated the preoperative MRI presentation and the treatment of 29 patients who were diagnosed missed Monteggia fracture. Radiologic and clinical results of these patients were evaluated retrospectively, and the patient’s and surgical factors related to preoperative radial notch/head appearance and the postoperative radiographic results were analyzed. Of the 29 patients, the average Kim elbow performance score at the last follow-up was 93.6, with 25 excellent, three good, one fair, and no poor results. 19 children had reduced radial heads, 8 had a subluxated radial head and 2 had dislocated radial heads at the last follow-up. The patient’s gender and age had no significant influence on the appearance of radial notch/head and final radiographic results. However, the appearance of radial notch/head can significantly affect the final radiographic result (P < 0.001). The interval time was an important factor which related with the appearance of radial notch/head and final radiographic results (P < 0.001). Treating a missed Monteggia fracture by open reduction of the radial head and corrective osteotomy of the ulna is generally successful and preoperative MRI is meaningful for evaluation of the condition of the radial head and the radial notch which is related with the final radiographic result. The interval time from injury to operation exceeds 6 months, the risk of radial notch/head abnormality and radial head subluxation/re-dislocation after operation significantly increase.

Abstract
Background Acute Monteggia fracture (AMF) is defined as a fracture of the proximal ulna combined with a dislocation of the radial head, with less than 1 percent prevalence in pediatric patients with an elbow injury. This retrospective study aimed to compare the efficacy of two treatment methods for oblique ulnar fracture AMF Bado type I in children. Methods In this retrospective study, 28 children with oblique ulnar fracture acute Monteggia injury Bado I were included. Patients was divided into two groups: In the EIN group 16 patients were fixed with elastic intramedullary nail after reduction, and in the LCP group 12 patients were fixed with locking compression plate after reduction. Operation time and blood loss were recorded and the patients were assessed clinically by the Mayo Elbow Performance Score (MEPS), range of movement(ROM) and range of rotation(ROR). Results Twenty-eight patients were accessible for durable follow-up, with a mean age of 7.7 ± 1.3 years, follow up by 33.7 ± 5.1 months. The average operation time was 48.1 ± 9.2 min for the EIN group and 67.1 ± 7.2 min for the LCP group. The average blood loss was 8.2 ± 2.3 ml for the EIN group and 18.8 ± 3.8 ml for the LCP group. The average operation time and average blood loss in the EIN group are significant less than the LCP group. Mean MEPS, ROM, ROR in both group improved significantly before sugery to three months after surgery, and maintained very good results at last follow up. There is no significant difference between the EIN group and the LCP group in MEPS, ROM and ROR. Conclusions Oblique ulnar fracture Bado type I acute monteggia fracture in pediatric patients fixed by EIN and LCP can both get good mid-term results measured by MEPS, ROM and ROR, Fixed by EIN have shorter operation time and less blood loss than fixed by LCP.

Abstract
BACKGROUND We aimed to analyze surgical outcomes of reconstructive surgery for chronic Monteggia fracture, which is one of the most challenging problems for orthopaedic surgeons. METHODS Twenty-eight patients were followed during 55.6 ± 32.0 months after open reduction of the radial head combined with ulnar osteotomy and annular ligament reconstruction. The mean interval from trauma was 15.1 ± 19.6 months, and the mean age at the surgery was 9.1 ± 3.5 years. In addition to the chronological age, elbow maturity was assessed using the Sauvegrain score. Surgical outcomes were primarily evaluated using the Kim's score. In addition, we newly defined more successful criteria for the ideal surgical outcomes, equivalent to preinjury status. RESULTS There were 19 excellent, 3 good, 4 fair, and 2 poor outcomes based on the Kim's scoring system. Among the 19 patients with excellent outcomes, 14 met our criteria for the ideal outcomes. The age (p < 0.001) and the Sauvegrain score (p < 0.001) were lower, and the interval (p = 0.004) was shorter in 14 patients with ideal outcomes. There were 9 patients with preoperative deformation of the radial head, and all of them showed non-ideal outcomes. In regression analyses, lower Sauvegrain score (p = 0.004) and shorter interval (p = 0.012) were associated with higher postoperative Kim's score, and lower Sauvegrain score (p = 0.031) was related to the achievement of the ideal outcomes. With the Sauvegrain score of >21.5, all patients had postoperative re-dislocation or osteoarthritic changes regardless of the interval. With the Sauvegrain score of <21.5 and an interval of ≤7 months, the ideal outcomes were achieved in 85.7%, and no patients had postoperative re-dislocation or osteoarthritic changes. CONCLUSION Over the skeletal ages of 14 years in boys and 11.5 years in girls, reconstructive surgery must be cautiously indicated. Under these skeletal ages with an interval of ≤7 months and undeformed radial head, it appears to be ideal. STUDY DESIGN Level III, Retrospective comparative study.

Abstract
BACKGROUND The treatment of chronic Monteggia fracture-dislocation (CMF) remains controversial and challenging for surgeons. We describe our initial experience with ulnar osteotomy and angulation on correction with modified open surgery and evaluate outcomes from clinical and radiographic findings. METHODS We retrospectively reviewed 18 children with a mean age of 6.78±2.67 years old who underwent surgical treatment because of CMF. Electronic medical records of Bado type, complaints, Kim scores, and complications were recorded. Radiographic parameters of maximum interosseous distance (MID), proportional ulnar length (PUL), lengthening, and bending angle of the ulna were summarized. The final reduction statuses of the radial head were reviewed. Parameters were compared at the time of pre-operation and the last follow-up. The relationship between the lengthening and angulation of ulna and the interval was calculated. RESULTS The mean interval was 11.1 [1-48] months and the follow-up time was 46.6 [24-96] months. A good reduction was observed in 15 (83.33%) patients, while 3 (16.67%) patients were fair. Postoperatively, the Kim scores were improved, from 59.17±18.17 to 90±6.64 (P=0.000). The mean posterior bending angle was 12.88° (range, 3 to 25°), and the mean amount of elongation of the ulna was 8.78 mm (range, 3.61 to 17.52 mm). The lengthening of the ulna was proportional to the magnitude of angulation of the ulna (r=0.648, P=0.004), and a positive correlation was also seen between the lengthening and the interval (r=0.632, P=0.005) and the angulation and the interval (r=0.502, P=0.034). The PUL and MID were significantly increased from 1.06±0.03 and 1.11±0.26 to 1.13±0.11 (P=0.047) and 1.28±0.27 (P=0.021), separately. CONCLUSIONS We highlight ulnar osteotomy as the essential procedure during reconstruction surgeries. Stabilization of the radial head with adequate elongation and balanced angulation of the osteotomy through direct observation is the main way to ensure and maintain satisfactory outcomes. With the extension of the interval, it is more necessary to increase the lengthening and angulation in positive proportion. PUL is a useful parameter in evaluating the mismatch between ulna and radius in CMF.

Abstract
INTRODUCTION Monteggia fracture-dislocation refers to traumatic ulnar fractures and dislocation of the radial head, which is one of the most frequently missed injuries, especially in children. The most widespread attitude towards chronic Monteggia lesion is the open reduction of the radial head associated with ulnar osteotomy with or without annular ligament reconstruction. Our study aimed to analyze the risk factors for redislocation after surgical management of chronic Monteggia lesion and the benefits of annular ligament reconstruction and radiocapitellar pinning in paediatric. MATERIALS AND METHODS We retrospectively reviewed patients treated with reconstruction surgery for chronic Monteggia fracture-dislocation in our department between 2005 and 2017, with a minimum two years' follow-up. The reconstruction surgery included ulnar osteotomy performed in all patients, annular ligament repair or reconstruction or fixation of radiocapitellar joint, or radial osteotomy in some patients. We collected the related clinical data and evaluated the risk factors of redislocation using logistic regression analyses and a two-piecewise linear regression model with a smoothing function, after reconstruction. RESULTS Throughout a mean six years' follow-up (range, 2-14 years), 62 patients (42 males, 20 females; average age 6.49 years range, 2-13 years) were reviewed. Of the radiocapitellar joints, 16.1% was noted to have redislocation. Univariate risk analysis showed age, time from injury to surgery, and radial osteotomy were risk factors for a recurrent radiocapitellar redislocation. Time from injury to surgery was found to be independent predictor of redislocation in multivariate analysis. However, there were significant nonlinear associations between time from injury to surgery and redislocation in multivariate logistic regression analysis after multivariate adjustment (p for nonlinear = 0.023). Every one month increase was associated with a 1.37-fold increase in redislocation, in participants within one year after injury. CONCLUSION In conclusion, the surgery of chronic Monteggia fracture-dislocation should be done as quickly as possible within one year after injury. Associated annular ligament reconstruction or fixation of radiocapitellar joint does not seem to be helpful.

Abstract
PURPOSE Opening-wedge osteotomy of the ulna restores normal ulnar length and corrects the angulation of the ulna in patients with chronic Monteggia fracture-dislocations. In addition, this eases the reduction of the radial head. Morbidity caused by annular ligament reconstruction surgery can be prevented by preserving the intact annular ligament. After dilatation and mobilization of the annular ligament, reduction of the radial head can be accomplished. This study evaluated the effectiveness of corrective opening-wedge ulnar osteotomy and radial head relocation into the intact annular ligament in the treatment of radiocapitellar instability secondary to pediatric chronic Monteggia fracture-dislocation. METHODS Fourteen patients diagnosed with radial head dislocation associated with plastic deformation of the ulna or ulnar fracture were included in the study. Radiologic and clinical results of these patients who underwent corrective ulnar osteotomy and radial head relocation into an intact annular ligament were evaluated retrospectively. RESULTS The mean age of the patients at the time of injury was 7.4 years (range, 3 years to 12 years). The average time between the injury and surgery was 19.1 months (median, 8 months; range, 3 months to 66 months); the average follow-up period was 28.7 months (range, 12 months to 60 months). The mean Kim score was 69.6 (range, 50 to 75) preoperatively and 92.9 (60 to 100) at last follow-up. According to Kim score, the results were considered excellent in 12 cases and poor in 2 cases. Radial head subluxation recurred in 2 separate cases. In addition, chondrolysis changes were seen in 1 case. Reduction loss and osteoarthritic changes in the radiocapitellar joint were considered poor results in follow-up radiographs. CONCLUSIONS Corrective ulnar osteotomy and relocating the radial head into the intact annular ligament can be safely used for treating chronic Monteggia fracture-dislocation cases without radial head and capitellum deformity.

Abstract
OBJECTIVES To review surgical management and outcomes of missed pediatric Monteggia fractures. DATA SOURCES A systematic review was conducted using PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), and the Cochrane Library from inception through March 2, 2020. The keywords were "Monteggia fracture," "missed Monteggia," "neglected Monteggia," "chronic Monteggia," and "chronic radial head dislocation." STUDY SELECTION All original human studies on missed pediatric Monteggia fractures were included. Congenital Monteggia fractures and isolated radial head dislocations were excluded. DATA EXTRACTION The revised Methodological Index for Nonrandomised Studies tool was used to assess the quality of studies. DATA SYNTHESIS Each patient's data were retrieved individually. The χ2 test and Fisher exact test were used to analyze the difference in outcomes for different surgical managements. Multivariate analysis was performed for variables that were significant on univariate analysis. CONCLUSIONS Thirty studies with 600 patients were included. Proximal ulnar osteotomies (P = 0.016) and the absence of transcapitellar pinning (P = 0.001) were the most significant predictors for eventual reduction of radial head. Other surgical management variables were not significant predictors. These include open or closed reduction approach of radial head reduction; presence or absence of ulnar osteotomy; presence or absence of lengthening, angular correction, overcorrection, or bone grafting of ulnar osteotomy; type of fixation for ulnar osteotomy; presence or absence of radial osteotomy; presence or absence of annular ligament repair or reconstruction; and repair or reconstruction of annular ligament. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

The incidence of untreated Monteggia fracture-dislocations is not insignificant. But there is no consensus as to the surgical indication and best surgical technique to use. Single-stage reduction of the radial head through an elbow arthrotomy and ulnar osteotomy is a complex surgical procedure that requires stabilization of the ulnar segments during every step of the intervention. Here, we describe the possibility of using an external fixator intraoperatively to facilitate the various steps of the procedure: (1) gradual distraction and angulation of the osteotomy site to allow thorough excision of any interposed capsular tissue, (2) stable hold on the ulnar fragments independent of the surgical assistant, which allows the stability of the radial head reduction to be tested in pronation and supination and (3) facilitation of plate fixation at the ulnar osteotomy site. LEVEL OF EVIDENCE: IV; case series.

Abstract
A neglected Monteggia fracture is defined as the fracture of the proximal ulna associated with radial head dislocation (RHD) without undergoing any treatment for 4 weeks or more after injury. One-stage operation of ulnar corrective osteotomy and open reduction of RHD might result in many complications. Therefore, a two-stage strategy, including ulnar osteotomy (UO) with or without annular ligament reconstruction (ALR), was adopted at our institute since 2010.We performed a retrospective review of 51 patients with neglected Monteggia fracture between January 2010 and January 2018. Patients with bilateral problems or concomitant injuries in the ipsilateral extremity were excluded. Radiological and clinical data were collected from Hospital Database and clinical visits. All patients were divided into 2 groups based on the status of the ALR: the UO alone (UO) group and the ALR group.There were 15 patients in the UO group and 36 patients in the ALR group. The age in the UO group (6.1 ± 2.3, year) was significantly younger than the ALR group (9.8 ± 2.8, year) (P < .001). Concerning the duration from initial injury to surgery, there was a significant difference between the UO group (8.6 ± 3.2 months) and the ALR group (23.3 ± 12.6 months, P < .001). Concerning the preoperative elbow function, there was no significant difference between the UO group (67.6 ± 5.0) and the ALR group (66.6 ± 4.4) according to the Mayo elbow performance score (MEPS) (P = .51). Concerning the postoperative parameters, including postoperative ROM of the joint, removal of external fixator (6.7 ± 0.8, 6.9 ± 0.9 weeks) (P = .55), lengthening (8.9 ± 2.5, 10.3 ± 2.5 mm) (P = .10) and MEPS (92.7 ± 2.1, 91.6 ± 2.1) (P = .08), there was no significant difference between the UO group and ALR group.Two-stage strategy is a reasonable choice for selected patients with long-lasting RHD with ulnar deformity.

Abstract
BACKGROUND In missed Monteggia fracture (MMF) cases, ulnar angulation and lengthening by osteotomy are required to reduce the dislocated radial head. This study aimed to clarify the abnormal discrepancy in length between the radius and ulna in MMF. We tested the hypothesis that the increase in the abnormal discrepancy in length between the radius and ulna relates with the duration of radial head dislocation. METHODS In total, 24 patients with MMF were studied and classified into 2 groups, according to the duration of radial head dislocation, including the early group (n=9, within 3 y) and the long-standing group (n=15, older than 3 y). The lengths of the radius (Lr) and ulna (Lu) were measured. The difference in length between the ulna and radius (DL=Lu-Lr) was calculated on both the affected (DLaff) and normal (DLnor) sides. DLnor-DLaff, which represented an abnormal discrepancy in both bones, was analyzed for correlation with the duration of radial head dislocation and the age at initial injury. RESULTS The affected and normal sides had no differences in the Lr of both the groups and in the Lu of the early group. However, in the long-standing group, Lu was significantly smaller in the affected side than in the normal side (P=0.001). In the long-standing group, DLaff was significantly smaller, owing to decreased length of the ulna, than DLnor (P=0.003). The DLnor-DLaff was positively correlated with the duration of radial head dislocation and was negatively correlated with the age at injury. CONCLUSIONS In chronic MMF cases, the length of the ulna was shorter in the affected side than in the normal side. Therefore, ulnar lengthening is necessary to resolve this abnormal discrepancy and reduce the radial head. Because excessive ulnar lengthening has risks of postoperative complications, one of the surgical options is gradual ulnar lengthening or shortening osteotomy of the radius. LEVEL OF EVIDENCE Level III-Prognosis study.

Abstract
Background Monteggia fracture-dislocation is a rare and often missed injury in the paediatric population. The neglected radial head dislocation might go unnoticed for several months, but usually becomes symptomatic at a certain point in time, posing a complex clinical problem. Management strategies for chronic Monteggia lesions have been proposed by many authors. A consensus therapy is nonetheless lacking. In recent years an increasing number of case series reporting the outcomes of various treatment options have been published to gain insight into this challenging pathology. The purpose of this review is to provide a general background on chronic, paediatric Monteggia fracture-dislocation, followed by a systematic analysis and discussion of various management strategies and their outcomes, described in recent outcome studies. Methods A literature search was conducted within the online databases PubMed, Cochrane Central, EMBASE and Google Scholar, to identify outcome studies on the management of chronic Monteggia lesions published between January 2015 and April 2020. A total of 23 outcome studies were identified and included in this study. Results Obtaining stable radial head reduction can be regarded as the main objective of any management strategy for chronic, paediatric Monteggia fracture-dislocation. In recent literature, many surgical techniques have been put forward to obtain this goal, with the mainstay of most treatment strategies being ulnar osteotomy and open reduction with or without reconstruction of the annular ligament. Watchful neglect is a strategy that got more or less abandoned and is challenged in recent literature. Conclusions Due to the complexity of long-standing radial head dislocation and the unpredictability of outcomes in the treatment of chronic Monteggia lesions, early diagnosis and achieving a stable reduction, preferably in the acute setting, are paramount. Because of the tendency to obtain more satisfactory radiological and clinical results in younger patients, with a short injury-to-surgery interval, it is advisable to promptly proceed to surgical treatment when chronic Monteggia fracture-dislocation is diagnosed.

Abstract
Objective Missed Monteggia fractures are commonly observed among children. Both the interval from the injury to surgery and the patient’s age at operation are thought to be correlated directly with the success of the surgery and prognosis. The aim of the present work was to report one interesting adult case of a missed Monteggia fracture with an intact annular ligament 9 years after injury and the outcomes at a 7-year follow-up. Case description One missed lesion with a 9-year delay for surgery occurred in a skeletally mature individual, and it was treated by open reduction and ulnar angulation and elongation osteotomy. The annular ligament was interpositioned intact in the radiocapitellar joint, and therefore, instead of the annular ligament reconstruction (ALR), relocation was performed. Results After one revision surgery for the complication of nonunion, good radiographic and functional outcomes were eventually sustained at the 7-year follow up. Conclusion Good radiographic and functional outcomes can be expected in adult patients in whom the annular ligament is intact and interpositioned, and this was treated by open reduction and ulnar osteotomy 9 years after the initial injury in our patient.

Abstract
Aims The Wrightington classification system of fracture-dislocations of the elbow divides these injuries into six subtypes depending on the involvement of the coronoid and the radial head. The aim of this study was to assess the reliability and reproducibility of this classification system. Methods This was a blinded study using radiographs and CT scans of 48 consecutive patients managed according to the Wrightington classification system between 2010 and 2018. Four trauma and orthopaedic consultants, two post CCT fellows, and one speciality registrar based in the UK classified the injuries. The seven observers reviewed preoperative radiographs and CT scans twice, with a minimum four-week interval. Radiographs and CT scans were reviewed separately. Inter- and intraobserver reliability were calculated using Fleiss and Cohen kappa coefficients. The Landis and Koch criteria were used to interpret the strength of the kappa values. Validity was assessed by calculating the percentage agreement against intraoperative findings. Results Of the 48 patients, three (6%) had type A injury, 11 (23%) type B, 16 (33%) type B+, 16 (33%) Type C, two (4%) type D+, and none had a type D injury. All 48 patients had anteroposterior (AP) and lateral radiographs, 44 had 2D CT scans, and 39 had 3D reconstructions. The interobserver reliability kappa value was 0.52 for radiographs, 0.71 for 2D CT scans, and 0.73 for a combination of 2D and 3D reconstruction CT scans. The median intraobserver reliability was 0.75 (interquartile range (IQR) 0.62 to 0.79) for radiographs, 0.77 (IQR 0.73 to 0.94) for 2D CT scans, and 0.89 (IQR 0.77 to 0.93) for the combination of 2D and 3D reconstruction. Validity analysis showed that accuracy significantly improved when using CT scans (p = 0.018 and p = 0.028 respectively). Conclusion The Wrightington classification system is a reliable and valid method of classifying fracture-dislocations of the elbow. CT scans are significantly more accurate than radiographs when identifying the pattern of injury, with good intra- and interobserver reproducibility.

Abstract
PURPOSES To evaluate the outcome of different types of ulna osteotomy in missed Monteggia fracture with a particular interest in anatomical correction and overcorrection techniques. The outcome between the two groups were compared on aspects of (1) clinical outcome (2) radiologic outcome. METHODS Twenty-one patients with type 1 missed Monteggia fracture who underwent surgery between January 2005-2018 were retrospectively reviewed. The patients were divided into two groups according to the degrees of correction: group 1 anatomical correction (no ulnar dorsal angulation) and group 2 overcorrection (degrees of ulnar dorsal angulation ≥ 10°). Clinical outcomes were assessed using the Kim elbow performance score. Radiologic outcomes were categorized into four groups with regard to the radial head: excellent (complete reduction), good (slight subluxation), fair (moderate subluxation), and poor (dislocation). RESULTS Eleven patients with anatomical ulna osteotomy and ten patients with overcorrection ulnar osteotomy were enrolled with a mean age of 7.95 (5-12) years at the time of operation. The mean duration from injury to surgery was 27.05 (3-120) months, and the mean period of follow-up was 29.90 ± 22.37 (12-84) months. The average angle of total correction measured in group 1 was 6.09° (3°-9°) and 28.37° (12°-40°), in group 2. Fair-to-poor radiological outcomes at the last follow-up were more frequently observed in overcorrection group (40% vs. 0%) (p = 0.035) as well as clinical outcome (20% vs. 0%) (p = 0.214). Among the patients in group 2, posterior dislocation was diagnosed in two patients at 18 months and 2 months after surgery. CONCLUSION The postoperative result of overcorrection ulna osteotomy showed significant inferiority in radiologic outcome compared to anatomical correction. Overcorrection of ulna osteotomy could be associated with posterior dislocation of radial head.

Abstract
The treatment of a missed Monteggia (MM) fracture dislocation is still controversial. We describe our initial experience with ulnar osteotomy and progressive correction with unilateral external fixator in MM. We retrospectively evaluated 20 children undergoing ulnar osteotomy and progressive distraction angulation by unilateral external fixator to treat MM. Nine patients had closed reduction, whereas 11 patients had simultaneous open reduction, repair, or reconstruction of the annular ligament and K-wire stabilization of the radiocapitellar joint. Patients were followed for an average of 3 (1-11) years. Three children developed aseptic nonunion and one child had delayed union. A distal level of the osteotomy significantly increased the rate of nonunion or delayed union. At the final follow-up, eight children had complete reduction of the radial head, six children had partial reduction, whereas in six cases, the radial head remained dislocated. The angulation and the level of the osteotomy significantly influenced the relocation, whereas the open reduction had no significant effect on the final position of the radial head. At the final follow-up, the Kim's score averaged 93.25. The flexion-extension arc significantly improved postoperatively, and it was positively correlated with the angulation. The ulnar osteotomy and progressive traction-angulation by unilateral external fixator can achieve satisfactory results in MM, if a meticulous surgical technique is applied; care must be taken regarding the level of osteotomy and the progressive traction-angulation.

Abstract
Various methods are applied in the treatment of fresh and neglected Monteggia fractures. The purpose of this retrospective study was to evaluate the efficacy of various treatment methods, and assess the complexity associated with missed radial head dislocation.All fracture patients were reviewed between Jan 2012 and Dec 2016. A detailed comparison was made of the treatment methods between fresh Monteggia fractures and neglected Monteggia fractures with missed diagnosis of dislocation.A preliminary analysis of clinical information from 1081 patients in our center was investigated, and 42 were included in the final analysis. The fresh group included 25 patients with an average Mayo Elbow Performance Score of 96.3 ± 2.7 and resulted in the following scores after treatment: 21 excellent, 3 good, and 1 fair. In the fresh group, 76% of patients received closed reduction. Treatment with a cast, elastic stable intramedullary nail, and the Kirschner wire stabilization with tension band wiring make up 80% of the choices for fixation treatment. No patients experienced associated vascular injuries, recurrent dislocation, or elbow dysfunction. The neglected group involved 17 patients with Mayo Elbow Performance Score of 92.1 ± 9.3 and resulted in the following scores after treatment: 10 excellent, 4 good, and 3 fair. The locking compression plate (LCP) was the most common choice for postoperative immobilization in the neglected group (88.2%). Three patients in the neglected group experienced recurrent dislocation.This retrospective analysis indicates that the treatment of neglected Monteggia fractures is more complex than that of fresh Monteggia fractures, and usually results in a worse recovery rate with a higher rate of recurrent dislocation and elbow dysfunction.
