Aims. To investigate the risk factors for unsuccessful radial head reduction (RHR) in children with chronic Monteggia fractures (CMFs) treated surgically. Methods. A total of 209 children (mean age 6.84 years (SD 2.87)), who underwent surgical treatment for CMFs between March 2015 and March 2023 at six institutions, were retrospectively reviewed. Assessed risk factors included age, sex, laterality, dislocation direction and distance, preoperative proximal radial metaphysis width, time from injury to surgery, reduction method, annular ligament reconstruction, radiocapitellar joint fixation, ulnar osteotomy, site of ulnar osteotomy, preoperative and postoperative ulnar angulation, ulnar fixation method, progressive ulnar distraction, and postoperative cast immobilization. Independent-samples t-test, chi-squared test, and logistic regression analysis were used to identify the risk factors associated with unsuccessful RHR. Results. Redislocation occurred during surgery in 48 patients (23%), and during follow-up in 44 (21.1%). The mean follow-up of patients with successful RHR was 13.25 months (6 to 78). According to the univariable analysis, time from injury to surgery (p = 0.002) and preoperative dislocation distance (p = 0.042) were identified as potential risk factors for unsuccessful RHR. However, only time from injury to surgery (p = 0.007) was confirmed as a risk factor by logistic regression analysis. Receiver operating characteristic curve analysis and chi-squared test confirmed that a time from injury to surgery greater than 1.75 months increased the rate of unsuccessful RHR above the cutoff (p = 0.002). Conclusion. Time from injury to surgery is the primary independent risk factor for unsuccessful RHR in surgically treated children with CMFs, particularly in those with a time from injury to surgery of more than 1.75 months. No other factors were found to influence the incidence of unsuccessful RHR. Surgical reduction of paediatric CMFs should be performed within the first two months of injury whenever possible.

Introduction. Early identification and conservative management of paediatric Monteggia fractures has been shown to correlate with good results. Nevertheless, several authors advocate more aggressive management with open reduction and internal fixation (ORIF) for unstable fractures. We herein present the experience of a tertiary paediatric hospital in the management of Monteggia fractures. Methods. 41 patients with Monteggia fractures (26 male and 15 female) were admitted and treated over a period of 20 years (1989 to 2009). The age of the patients ranged between 3 and 14 years (mean 7.5 years). Based on the Bado Classification, 29 fractures were type I, 3 were type II, 8 type III and 1 fracture was classified as type IV. Out of the 41 patients, 32 were managed with manipulation under anaesthesia (MUA) and above elbow plaster, whereas 9 underwent open reduction and internal fixation (ORIF) of the ulna. Results. In order to assess outcomes, the Bruce, Harvey and Wilson scoring system was used. Assessment of range of movement, pain and deformity are evaluated to class an outcome as excellent, good, fair or poor. Patients were followed up for an average of 4.6 years (range 1 to 7). All the patients in the MUA group had excellent results. In the ORIF group 8 out of 9 patients had good results. The only patient with a fair outcome was presented 3 weeks post injury and was managed with osteotomy and ORIF of the ulna. Discussion and conclusion. According to our recorded experience conservative management of Monteggia fractures, when indicated, results in excellent outcomes. In cases where emergency MUA fails to achieve or maintain reduction, the choice of ORIF has also demonstrated good results. Early diagnosis and management are of paramount importance as mismanaged cases demonstrate the less satisfactory results

We present an original method for the treatment of neglected Monteggia fractures using the Ilizarov technique. This method allows reduction without accessing the radial head by progressive ulnar lengthening after proximal subperiosteal osteotomy of the ulnar bone. We used this method in a six and a half year old girl and achieved excellent radiographical and functional results with normal joint amplitudes. In our opinion, the quality of the outcome is related to the progressiveness of the bone lengthening enabled by this technique which allows restoration of the ulnar length, preservation of the axes of both forearm bones, and controlled reduction of the radial head

Abstract: Monteggia fracture dislocation in an uncommon injury in children. In the less severe injuries, with minimum angulation of the ulnar fracture, the radial head dislocation is frequently missed. The treatment of these late recognised injuries (more than one month) remains controversial, with frequent complications and high failure rates reported in literature. We have devised a new operative technique which has proved so far to be very successful and reliable. The procedure can be recommended only for children who have no major intra-articular injury, no epiphyseal damage and only mild adaptive changes of the radial head. It is also contraindicated if there is significant overgrowth of the radius as well as secondary changes in the proximal and distal radioulnar joints. The parents are warned of possible complications and residual loss of some movements. Under general anaesthesia, a curved longitudinal incision is made centred over the ulnar deformity extending proximally to the lateral epicondyle. The essence of the operation is the oblique ulnar metaphyseal osteotomy. The cut is made starting proximal medial to distal lateral. The osteotomy recreates the instability allowing open reduction of the radial head. It also allows for ulnar lengthening by the sliding of the osteotomised surfaces with graft interposition if necessary. The radial head is approached between the anconeus and wrist extensors, through the same exposure. The annular ligament is dividend and radial head reduced into its anatomical position. The ulna is securely fixed in the angulated position using a one third tubular plate. Finally, after checking the stability of the radial head in all forearm movements, the annular ligament is repaired. An above elbow cast is applied with forearm in supination and elbow in 90 degrees of flexion. The cast is worn for six weeks, with weekly check radiographs. Active use of the arms is encouraged after this with follow up at increasing intervals. The follow up of our cases has shown that the ulnar angulation completely remodels, with normal development of the radial head. A functional range of forearm rotation and full flexion/extension at the elbow are regained with time. We have not noted any residual subluxation/dislocations in our cases

Aims. To propose a new method for evaluating paediatric radial neck fractures and improve the accuracy of fracture angulation measurement, particularly in younger children, and thereby facilitate planning treatment in this population. Methods. Clinical data of 117 children with radial neck fractures in our hospital from August 2014 to March 2023 were collected. A total of 50 children (26 males, 24 females, mean age 7.6 years (2 to 13)) met the inclusion criteria and were analyzed. Cases were excluded for the following reasons: Judet grade I and Judet grade IVb (> 85° angulation) classification; poor radiograph image quality; incomplete clinical information; sagittal plane angulation; severe displacement of the ulna fracture; and Monteggia fractures. For each patient, standard elbow anteroposterior (AP) view radiographs and corresponding CT images were acquired. On radiographs, Angle P (complementary to the angle between the long axis of the radial head and the line perpendicular to the physis), Angle S (complementary to the angle between the long axis of the radial head and the midline through the proximal radial shaft), and Angle U (between the long axis of the radial head and the straight line from the distal tip of the capitellum to the coronoid process) were identified as candidates approximating the true coronal plane angulation of radial neck fractures. On the coronal plane of the CT scan, the angulation of radial neck fractures (CTa) was measured and served as the reference standard for measurement. Inter- and intraobserver reliabilities were assessed by Kappa statistics and intraclass correlation coefficient (ICC). Results. Angle U showed the strongest correlation with CTa (p < 0.001). In the analysis of inter- and intraobserver reliability, Kappa values were significantly higher for Angles S and U compared with Angle P. ICC values were excellent among the three groups. Conclusion. Angle U on AP view was the best substitute for CTa when evaluating radial neck fractures in children. Further studies are required to validate this method.

The October 2012 Children’s orthopaedics Roundup. 360. looks at: magnetic growing rods and scoliosis correction; maintaining alignment after manipulation of a radial shaft fracture; Glaswegian children and swellings of obscure origin; long-term outcome of femoral derotation osteotomy in cerebral palsy; lower-leg fractures and compartment syndrome in children; fractures of the radial neck in children; management of the paediatric Monteggia fracture; and missing the dislocated hip in Western Australia

Background. Chronic acquired radial head dislocations pose a complex problem in terms of surgical decision making, especially if surgery has already previously failed. There are several underlying causes that should be investigated, including previous trauma resulting in a missed Monteggia fracture. Aim. To review the clinical and radiological outcomes for children up to 18 years of age, with a radial head dislocation treated with circular frame surgery. Method. A retrospective study was designed to identify patients from our departmental database who had undergone circular frame surgery to reduce the radial head during the past 6 years. Results. 20 patients were identified with a mean age of 11 years (3 – 17). Fourteen patients had a diagnosis of missed Monteggia fracture, three patients had Hereditary Multiple Exostoses, one had Nail Patella syndrome, one had Osteogenesis Imperfecta and one had rickets. The average delay between trauma and frame surgery was three years (0 – 7). All patients achieved union of their ulnar or radial osteotomy. The average frame duration was 167 days (61 – 325) and complications included delayed union and residual radial head subluxation. Thirteen patients achieved at least 40 degrees of supination, and 10 patients achieved at least 40 degrees of pronation. Eighteen patients achieved an arc of movement from full extension to at least 110 degrees of flexion. Eleven patients reported their pain level at final follow-up, of which 9 had no pain at all. Conclusion and Discussion. Circular frame surgery was a reliable and consistent method of reducing chronic radial head dislocations and improving function. Radiological appearances of mild residual subluxation of the radial head were clinically well tolerated and generally required no further treatment

Purpose of study: To report the use of a forearm fascial strip to repair the annular ligament and treat late diagnosed or irreducible Monteggia fracture. Methods: Through Boyd’s approach nineteen patients with Monteggia fractures were treated with a technique to reconstruct the annular ligament using forearm fascia, retaining its proximal attachment to the ulna. The radial head was dislocated and the fascial strip wound around the neck of the radius. After reducing the radial head, forearm rotation was checked. The strip was sutured to the residual annular ligament on the proximal ulna after correction of any ulna deformity. In late diagnosis, the ulna deformity was managed with ulna lengthening of approximately 0.5 cm and stabilization with a 4- or 5- hole semi-tubular AO plate. The stability of the radial head was then assessed using intra-operative fluoroscopy. Results: Stability of the radial head was achieved in all cases. According to the Anderson classification, the final outcome was excellent in ten cases satisfactory in eight cases and unsatisfactory in one late diagnosed patient with an associated radioulnar synostosis secondary to a compartment syndrome. There were no failures. Two radiocapitellar K-wires broke while in plaster in the initial period, so the use of a K wire was subsequently abandoned. Conclusions: We have found this technique to be reliable for stabilizing the proximal radioulnar joint. The length of the incision is less than that required for the Bell Tawse (triceps tendon) technique and permits a tourniquet on the upper arm. Poorer results were achieved with delay in diagnosis beyond 6 months. Patients must be warned of potential reduction of forearm rotation

Infection and re-fracture are well-described complications following open paediatric forearm fractures. The purpose of this paper is to determine if patient, injury, and treatment characteristics can be used to predict the occurrence of these complications following the surgical management of paediatric open forearm fractures. This is an IRB-approved retrospective review at a single-institution paediatric level 1 trauma centrefrom 2007–2013 of all open forearm fractures. Medical records were reviewed to determine the type of open fracture, time to administration of initial antibiotics, time from injury to surgery, type of fixation, length of immobilisation, and complications. Radiographs were studied to document fracture characteristics. 262 patients with an average age of 9.7 years were reviewed. There were 219 Gustillo-Anderson Type 1 open fractures, 39 Type 2 fractures, and 4 Type 3 fractures. There were 9 infections (3.4%) and 6 re-fractures (2.3%). Twenty-eight (10.7%) patients returned to the operating room for additional treatment; 21 of which were for removal of implants. Contaminated wounds, as documented within the medical record, had a greater chance of infection (21% vs 2.2%, p=0.002). No difference in infection rate was seen with regard to timing of antibiotics (p=0.87), timing to formal debridement (p=0.20), Type 1 versus Type 2 or 3 open fractures (3.4% vs 5.0%, p=0.64), 24 hours vs. 48 hours of post-operative IV antibiotics (5.2% vs 3.5%, p=0.53), or when comparing diaphyseal, distal, and Monteggia fracture patterns (3.6 vs 2.9% vs 5.9%, p=0.81). There was no difference in infection rate when comparing buried or exposed intramedullary implants (3.5% vs 4.2%, p>0.99). Rate of re-fracture was not increased based on type of open wound (p>0.99) or fracture type (0.4973), although 5 of the 6 re-fractures were in diaphyseal injuries. In this series of open paediatric both bone forearm fractures, initial wound contamination was a significant risk factor for subsequent infection. The rate of infection did not vary with timing of antibiotics or surgery, type of open fracture, or length of post-operative antibiotics. A trend to higher re-fracture rates in diaphyseal injuries was noted. Surgeons should consider planned repeat irrigation and debridement for open forearm fractures with obviously contaminated wounds to reduce the subsequent infection risk

The clinical case refers to a male patient, 34 years old, admitted at the Emergency Department after a fall of 2 meters. Of that trauma, resulted an exposed Monteggia fracture type III – Gustillo & Anderson IIA – on his left arm. With this work, the authors intend to describe the evolution of the patient's clinical condition, as well as the surgical procedures he was submitted to. The authors used the patient's records from Hospital's archives, namely from the Emergency Department, Operating Room, Infirmary and Consultation, and also the diagnostic exams performed throughout the patient's clinical evolution. The clinical case began in December 2011, when the patient suffered a fall of 2 meters in his workplace. From the evaluation in the Emergency Department, it was concluded that the patient presented, at the left forearm, an exposed Monteggia type III fracture – Gustillo & Anderson IIA – combined with a comminuted fracture of the radial head. At the admission day, the wound site was thoroughly rinsed, the fracture was reduced and immobilized with an above-the-elbow cast, and antibiotics were initiated. Six days after admission, the patient was submitted to open reduction with internal fixation with plate and screws of the fracture of the ulna and radial head arthroplasty. The postoperative period was uneventful. Two months after the surgical procedure, inflammatory signals appeared with purulent secretion in the ulnar suture. Accordingly, the patient was submitted to fistulectomy, rinsing of the surgical site and a cycle of antibiotics with Vancomycin, directed to the S. aureus isolated from the purulent secretion. The clinical evolution was unfavorable, leading to the appearance of a metaphyseal pseudarthrosis or the ulna and dislocation of the radial head prosthesis. The previously implanted material was therefore removed, 4 months after the traumatic event; at the same time an external fixation device was applied and the first part of a Masquelet Technique was conducted. The second part of the aforementioned procedure was carried out in December 2012. The patient was discharged from the consultation after a 2 years follow-up, with a range of motion of the left elbow acceptable for his daily living activities. In spite of the multiple surgical rinsing procedures and directed antibiotics, the development of a metaphyseal pseudarthrosis of the ulna was inevitable. This clinical case illustrates how the Masquelet Technique presents itself as a good solution for the cases of non-union of fractures in the context of infection

Purpose of the study: Complex fracture-dislocation of the elbow, and subsequent surgical treatment, is often the source of a stiff joint. The purpose of this study was to assess the efficacy of a therapeutic protocol combining systematic insertion of a dynamic external fixator allowing early mobilization of the elbow with restitution of the radial height and the coronoid process. Material and methods: This consecutive series of ten patient, six men and four women, mean age 49 years, age range 27–67 years, underwent surgery from 2002 to 2004. Three patients presented a posterior Monteggia fracture (two type IIA, one type IId associated with comminutive fracture of the trochlea), four patients presented a dislocation associated with a Masson 4 fracture of the radial head and two presented inveterated dislocations diagnosed three weeks after the traumatic event. In all, seven patients presented a fracture of the radial head and six a fracture of the coronoid process. For all patients, the operation consisted in stabilization with a dynamic external fixator of the elbow associated or not with restoration of the radial height with a radial head prosthesis (n=4) and reconstitution of the coronoid process (n=6). The lateral ligaments had to be reinserted in four elbows. The comminutive fracture of the rochlea was treated with an iliac crest graft. Results: One patient died early. One patient presented pin tract infection and four developed heterotopic ossifications. At mean follow-up of twelve months, outcome was excellent in our patients, good in four, fair in one (Mayo clinic classification). All patients had a stable elbow. The mean range of motion was 89° flexion-extension and 145° pronationsupination. Conclusion: In this series, systematic use of external fixation for complex fracture-dislocation of the elbow joint yielded satisfactory results when the element stabilizing the joint were appropriately restored and when rehabilitation was undertaken early

Aims

Isolated fractures of the ulnar diaphysis are uncommon, occurring at a rate of 0.02 to 0.04 per 1,000 cases. Despite their infrequency, these fractures commonly give rise to complications, such as nonunion, limited forearm pronation and supination, restricted elbow range of motion, radioulnar synostosis, and prolonged pain. Treatment options for this injury remain a topic of debate, with limited research available and no consensus on the optimal approach. Therefore, this trial aims to compare clinical, radiological, and functional outcomes of two treatment methods: open reduction and internal fixation (ORIF) versus nonoperative treatment in patients with isolated ulnar diaphyseal fractures.

Abstract: A review study of 40 skeletally immature patients with displaced, diaphyseal both-bone forearm fractures treated with open reduction, internal fixation of radius only, using Mini DCP/one third tubular plate. Forty children (age range 5–13 years), treated between 1987–1999 by one surgeon were evaluated subjectively for pain or restriction of activities at games or school, clinically for range of movements at elbow, wrist and forearm rotation, and radiologically for residual angulation and time at healing. Duration of follow up was 2–12 years. Galeazzi and Monteggia fractures, as well as fractures with metaphyseal involvement were excluded. Among 40 patients, 26 were male and 14 female. Fracture distribution was 4 (10%) upper third, 12 (30%) middle third and 24 (60%) lower third of radius and ulna. Healing time was 2–10 (mean 3.6 months). One patient went into non-union and required further surgery. One patient developed superficial cellulites around the wound, resolved by a week course of oral antibiotics. No other complications were noted. Subjective evaluation showed excellent results in all patients according to our criteria. Clinically all patients had full range of motion at elbow, wrist and forearm rotation, except two patients who were 5 degree short of pronation and one patient 10 degree short of both supination and pronation, as compared to their normal forearm. Radiologically, two patients showed residual angulation of 5 degree in ulna. We conclude that single bone fixation offers a safe and effective way of treating displaced diaphyseal fractures of both radius and ulna, with excellent functional outcome

Diaphyseal fractures can be divided into three groups comprising the basic types of fractures: fractures of both bones (radius and ulna), fracture dislocations, i.e., fractures of one of the bones accompanied by dislocation of the head of the other bone in the respective radioulnar joint, the Galeazzi fracture or the Monteggia fracture, and isolated fractures of one of the two bones – the radius or the ulna. Photographs are decisive for diagnosis of the anteroposterior and lateral projections. Each must simultaneously visualize the elbow and wrist joints in order not to neglect potential injuries located there. The basic aim is full restoration of the function of the forearm with emphasis on supination-pronation movement. This requires anatomical union particularly in regard to the ulna, which has a critical importance for the function of the forearm. In fracture dislocations, it is also necessary to restore stability in the respective radioulnar joint. For the above-mentioned reasons, almost all diaphyseal fractures (except for non-dislocated or minimally dislocated fractures of the ulna) are indicated for surgery. Our procedure depends on the condition of the fracture and the general condition of the patient. Plate fixation represents the gold standard for closed fractures – open fractures of Degrees I and II and some Degree III fractures classified according to Tscherne. More extensive defects of soft tissues require cooperation with a plastic surgeon. The standard implants are dynamic compression plates (3, 5 DCP) with holes for 3.5 mm cortical screws. The surgical approach to the ulna is relatively simple. In fractures of the proximal half of the radius, we prefer the Henry approach in fractures of the proximal half of the radius because, unlike the Thompson approach, it allows safe dissection up to the radial head without damaging the deep branch of the radial nerve. The main principle is a 3 + 3 fixation, meaning that the plate must be fixed to each of the two main fragments, minimally by three screws. An exception can be made in the vicinity of the joint when the fragment is too short to accommodate three screws

Introduction. Chronic radial head dislocation in children after trauma is a serious condition. Often the dislocation is overseen initially and is a part of the Monteggia fracture complex with anterior bowing of the ulna. Typical complaints are pain, decreased ROM and cubitus valgus. Radial head dysplasia often occurs. The treatment of this condition is debated. Only few series of patients treated with open reduction and ulnar osteotomy exists with long-term follow up. We present a group of rare patients with long-time follow-up treated by only two surgeons through a period of 16 years. Materials and Methods. All 16 patients had anterior radial head dislocation (Bado type 1). Mean age at the time of traumatic dislocation was 6 years ranging from 2 to 9. We found a mean delay of 17 (range 1–83) months before open reduction and ulnar open wedge osteotomy. In 8 cases reconstruction of the annular ligament was performed and in 6 patients temporary transarticular fixation of the radial head with a k-wire was performed. Follow-up time was 8 (range 3–17) years postoperatively. Patients were investigated with bilateral x-ray, arthrosis status, congruency of the radiocapitellar joint, Oxford Elbow Score, force measurements and range of motion. Results. There were no major complications to surgery such as infection, nerve palsies or pseudarthrosis. Radiological results showed 9/16 with reduction of the radial head and with no arthrosis, 4/16 with arthrosis or subluxation, and 2/16 with a dislocated radial head. We found a significant correlation between radiological outcome and delay to ulnar osteotomy (p = 0.03). At follow up the mean Function score was 92 (SD 9), Social/psychological score 83 (SD 14) and Pain score was 88 (SD 15). None of the patients with fully reduced radial head had progressed in increased valgus deformity. In contrast, one of two patients with postoperative secondary dislocation of the radial head had an increase in carrying angle on 25 degrees. Typical clinical findings were a small but significant extension deficit and median loss of supination on 10 grades ranging from 0–90 (p = 0.008). Five patients had subsequent surgery, of which one had an excision of the radial head 8 years after primary surgery. Ligament reconstruction or transfixation of the radial head did not influence the radiological or clinical outcome. Discussion and Conclusion. Case reports of similar patients treated conservatively demonstrate high morbidity and therefore open reduction and ulnar osteotomy is justified given the good clinical longterm outcome in the present study. However, this study underlines the importance of minimising the delay between trauma and open reduction. If surgery is performed before 40 months after trauma good to fair longterm radiological results can be obtained. After 40 months there is a high risk of recurrent luxation of the radial head

Introduction and objectives: This is a complex type of lesion that is frequently confused with Monteggia fracture. The objective of this paper is to analyse the experience of the Hospital Cl co San Carlos, in Madrid, in the management of the transolecranon fracture-dislocation of the elbow. Methods and material: Between 1988 and 2001 a total of 23 cases have been revised, 7 of them presenting an oblique simple fracture of the olecranon and the other 16 cases with a comminute one (with fracture of the coronoid process in 9 patients). There was also a radial head fracture associated in 7 patients. Two cases showed ulnar nerve palsy before surgery. Fifthteen of the 21 cases were males and 8 females, with a mean age of 37, 3 years (range: 17–71). The mean follow up was of 56 months (range: 22–122 months). The etiology was a traffic accident (bicycle, motorbike, car) in the 47, 6%, a casual fall in the 23, 8%, a sport accident in the 14, 2% and a precipitation in the 9, 5%. All of them were treated with open reduction and internal fixation, with plate and screws in 17 cases and tension-band wiring in 4 patients. When a radial head fracture was associated, reconstruction was performed with screws in 5 cases and radial head excision in 1 case. Anatomic reduction was achieved in 11 cases. Results: With the scale of Broberg and Morrey, excellent result was obtained in 6 cases, good in 8, fair in 6, and poor in the remaining 3. The most frequent complication was loss of motion (6 cases), followed by non-union in 2 cases (with hardware fatigue failure in 1 of them) and infection in other case. The two cases with preoperative ulnar nerve palsy resolved over a period of 4 months. Eleven patients needed a reoperation, performing a new internal fixation with bone grafting in 2 cases, a radial head prosthesis implanting in 1 case, and hardware removal in 8 cases. Discussion and Conclusions: Although the transolecra-non fracture-dislocation of the elbow can be included in several classifications (AO, de Cotton, de Schatzker, etc.), none of them accommodate it satisfactorily, because of the complexity of the lesion. Our results show a statistically significative relation (p < 0.05) between the anatomic reduction obtained and excellent or good results and a high frequency of joint stiffness in this severe lesion

Number one in frequency of all fractures in children is the distal forearm fracture. The most common green-stick fracture with minor or no dislocation is treated by short or long arm cast. Depending on the age 4 or six weeks of immobilization is sufficient. Displaced fractures of the distal radius and ulna are treated by closed reduction under general anaesthesia or lighter forms of analgesia. Reduction is followed by fixation in the “Schede position” (flexion, ulnar abduction) with obligatory change of cast after 10–14 days. Healing can be expected after 6 weeks. As an alternative percutaneous pinning of the reduced fracture allows immobilization in a short arm cast and without the the unpleasant flexion and ulnar abduction (. Voto et al 1990. , . Mani et al 1993. , . Gibbons et al 1994. , Choi et al 1959). There is currently a prospective randomised study running organized by Mr Clarke from Southampton, to the advantages and disadvantages after use of pins or abstaining from them apparent risks. For midshaft forearm fractures closed reduction and long arm cast immobilisation had been treatment of choice in the past. Remanipulation under anaesthesia because of lack of retention of both bone fractures have been common. Concerns came up mainly in the age group above 10 years with a high rate of unsatisfactory results (. Kay et al 1986. ). Plate fixation of both bones is a difficult procedure and causes damage to the interosseous membrane and can enhance rotatory deficits. In addition ugly scars are not unusual. Intramedullary nails seemed advantageous. (. Amit et al 1985. ). J.L. Morote and the Spanish school of Sevilla were the first to use a minimal invasive method of reduction and K-wire fixation of midshaft and proximal forearm fractures. (Perez-Sicilia et al 1977). The French group in Nancy and Metz had the some years later and developed their elastic stable intramedullary system for forearm fractures . Metaizeau 1988. , . Lascombes et al. 1990. ). A high rate of excellent outcomes and hardly any complications were observed. Intramedullary fixation with elastic stable nails even permits immediate motion (. Verstreken et al 1988. ). The surgical technique of Morote using blunt-ended 1,6 to 1,8 mm K-wires is described in “Operative Technique in Orthopaedics and Trauma” (. Parsch 1990. ) The results were confirmed by Kaye Wilkins (1996), . Luhmann et al 1998. , and . Richter et al 1998. An unacceptable high rate of complications was seen in groups, who used pins, which were not buried, who removed pins to early and before consolidation or who had fixed only one bone (. Cullen et al 1998. , . Shoemaker et al 1999. ). We recommend the intramedullary system for all displaced forearm fractures of children above 6 years until closure of the growth plate.(. Parsch 1990. ). The learning curve is short, the time of surgery an average of 40 minutes. The radiation exposure can be limited by the use of short impulse image intensifier. There is virtually no blood loss. With the learning curve more than 80 % can be fixed by closed means. Open reduction might be necessary in adolescents, or in delayed fracture care. Postoperative immobilisation is a plaster shell or brace is used for 2 weeks, this is not obligatory. Postoperative infections have not been observed after this minimal invasive method. Skin irritations can be avoided by complete bending of the K-wire ends. In unacceptable malunion after conservative treatment closed or open realignment of the fractures followed by intramedullary Morote pinning is the treatment of choice. Refractures may happen with wires in place shortly or a long time after removal of the hardware. They are not associated to the system, but rather to the fact that some children are subject to repeated falls, liable to break an arm. Acute Monteggia fractures have the radial head reduced conservatively, usually under general anaesthesia. (. Bado 1967. ). The ulnar fracture is reduced and than fixed by intramedullary K-wires (. Fowles et al 1983. ). In late reconstruction of Monteggia lesions we prefer plate fixation of ulna osteotomy

Purpose: To describe the pattern of injury, surgical technique and outcomes of Monteggia type IID fracture dislocations. Method: Design: Retrospective review of prospectively collected clinical and radiographic patient data in orthopaedic trauma database with prospectively collected outcome scores. Setting: Level 1 university based trauma center. Patients / Participants: All patients with Monteggia type IID fracture dislocations admitted from January 2000 to July 2005. Intervention: Review of patient demographics, fracture pattern, method of fixation, complications, additional surgical procedures, and clinical and radiographic outcome measures. Main Outcome Measurements: Clinical outcomes: elbow range of motion, QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand), PREE (Patient Rated Elbow Evaluation), complications. Radiographic outcomes: quality of fracture reduction, healing time, degenerative change and heterotopic ossification. Results: Sixteen patients were included in the study. All fractures united. There were seven complications in 6 patients including 3 contractures with associated heterotopic ossification, 1 pronator syndrome and late radial nerve palsy, 1 radial head collapse and a DVT in the same patient and 1 with prominent hardware. Outcome scores were obtained on 11 patients at an average of 49 months (range 25 – 82 months) post-operatively. The average Quickdash score was 11 (range 0–43) and the average PREE score was 13 (range 0–34). Conclusion: Monteggia IID fracture dislocations are complex injuries with a recurring pattern. Rigid anatomic fixation, early range of motion and avoidance of complications leads to a good outcome
