Outcome of open reduction and Kirschner wire fixation in pediatric radial neck fracture

Background: Radial neck fracture in children is rare. This study attempted to evaluate the outcome of surgically treated patients and any associated complications.Methods: This study evaluated 23 children under 15 years of age with radial neck fracture who were treated with open reduction between 2006 and 2016 to determine their range of motion, postoperative complications, and radiographic outcomes. The results were assessed clinically using the Mayo clinic elbow performance score. Results: The mean follow-up duration for patients was 34.6 months. The average postoperative angulation was 3.6º. Hypoesthesia was reported in only 9% of patients, and none of the patients complained of postoperative pain. The postoperative X-ray results were excellent in 60% and good in 40%. No radiographic complications were identified. The Elbow score was excellent in 87% and good in 13% (mean score, 96.74). There was a statistical relationship between range of motion limitations and age, degree of fracture, initial displacement, and surgical pin removal time.Conclusions: Although most patients accept the closed reduction method as a primary treatment, the present study suggests that an open-reduction approach has been associated with optimal therapeutic outcomes for patients in whom closed reduction was not satisfactory or indicated.

FUNCTIONAL OUTCOME OF DISPLACED PAEDIATRIC RADIAL NECK FRACTURE TREATED BY OPEN REDUCTION –A CASE REPORT

A pediatric radial neck fracture, is still a challenging problem for the treating orthopedic surgeon. We report a pediatric patient presenting with radial neck fracture and results of open reduction and xation with k wires. A 8-year-old right-handed boy fell on an out-stretched left arm after being tackled during playing kabaddi and had a radial neck fracture. At the rst radiologic examination, the anteroposterior and lateral radiographs were showing over 80 degrees of angulation at the radial neck and subluxation of the radiocapitellar joint. We tried to obtain a closed reduction, but we could not succeed. Then, we performed open reduction while preserving medial periosteal continuity and vascular supply of the radial head by meticulous surgical dissection. Sixth-month radiography control and clinical examination conrmed the complete healing of the fracture without any epiphyseal injury. Painless full range of motion without any restriction of pronation and supination was achieved. The patient and his parents were satised with the outcome. We conclude that, if we can preserve medial periosteal continuity and vascularity of the radial head with open reduction, satisfactory results are obtainable.

Monteggia equivalent lesion in children: a narrative review

BackgroundMonteggia equivalent lesion represents a group of injury or combined injury patterns that resemble the Monteggia lesion in its presentations and mechanisms. Unlike Monteggia lesions, the equivalent ones, which share vague definitions and mostly occur as sporadic single case reports in the literature, have not been thoroughly reviewed since Bado first proposed the term, especially in the pediatric population. The objective of this review was to elucidate the definition by elaborating on its clinical styles and thus analyzing the mechanism, diagnosis, and management through related literature.Data sourcesBased on the terms of ‘Monteggia equivalent’, ‘radial neck fracture’ and ‘pediatric’, all of the related literature was searched on the PubMed and Google Scholar search engine.ResultsThe advance of the definitions for pediatric Monteggia equivalent lesion (PMEL) was reviewed. The functional roles of the ulnar and the related mechanism theories in this injury were analyzed. The status of the radiocapitellar joint in this injury was emphasized. According to the previous statements, a new classification model was proposed and proper diagnosis and treatment approaches were suggested.ConclusionsPMEL should be defined as an ulnar fracture at any level combined with a proximal radial fracture. According to the status of the radiocapitellar joint, it could be divided into three groups. The occult ulnar bowing and delayed radial head dislocation should be a serious concern of orthopedists. Surgical need is usually warranted. Maintaining the ulnar length and securing the radiocapitellar joint are highly recommended.

Radiological and functional outcomes of modified Metaizeau technique in displaced radial neck fractures

The management of displaced radial neck fractures in children is still a controversial topic. The objective of this study is to examine the outcomes of modified Metaizeau technique in the children with displaced radius neck fractures. The retrospective study included 15 children with displaced radial neck fracture with an angulation of more than 30° who were managed with the use of leverage technique by mosquito clamps and internal fixation with elastic stable intramedullary nailing (ESIN). Radiological and functional assessments were performed during follow-up. Additionally, the patients were evaluated using Mayo Elbow Per- formance Score (MEPS). All the children could be managed with clamp-assisted closed reduction. The average duration of follow up was 25.5 ± 6.1 months (15-36 months). An excellent elbow function was achieved in all but one patient. Based on Metaizeau classification, excellent, good, fair, and poor outcomes were achieved in 11, 1, 2, and 1 patients, respectively. The average postoperative MEPS score was 98.7 ± 5.1 (80-100). Clamp-assisted closed reduction and fixation with ESIN is a good choice in the children with displaced radial neck fractures. This technique is associated with good functional and radiologic outcomes in the medium-term. Further studies are warranted with larger sample sizes.

Paediatric Radial Neck Fracture Fixation by Metaizeau Technique - Surgical Technique and Outcome

BACKGROUND Radial neck fractures in children are serious injuries with frequent sequelae when the tilt exceeds 60 degrees. Conservative treatment is often inadequate in such cases and open reduction may produce iatrogenic complications. Displaced radial neck fractures in the paediatric population can be treated with retrograde intramedullary nailing of the radius (the Metaizeau technique). This method allows early post-operative movement and thus has high functional outcome. The purpose of this case series was to evaluate the functional outcome of Metaizeau technique. METHODS This is a prospective study in which follow-up of 9 cases with radial neck fracture treated with Metaizeau technique was done. Clinical and radiological evaluation was done at 2 weeks, 4 weeks, 6 weeks and 6 months. Active range of motion of flexion and extension at elbow and forearm rotation was noted at 6 weeks along with pain score and Mayo Elbow Performance Score (MEPS). Radiological assessment was also done at 6 weeks regarding union. RESULTS 8 out of 9 cases had radiological union at 6 weeks. 1 case was lost to follow-up. Excellent result was obtained in all 8 cases. Range of flexion-extension, supinationpronation were identical in all 8 cases. 1 case developed pressure bursitis at entry site. CONCLUSIONS Metaizeau technique for radial neck fracture fixation is simple, safe, soft tissue sparing, minimally invasive technique giving excellent functional and cosmetic results with minimal complication.

Late Presenting Pediatric Radial Neck Fracture: A Case Report and Review of the Literature

Introduction: A pediatric radial neck fracture, when the diagnosis is delayed, is still a challenging problem for the treating orthopedic surgeon. We report a pediatric patient with late presenting radial neck fracture and results of open reduction and fixation with Kirschner wires. Case Report: A 13-year-old right-handed girl fell on an out-stretched right arm after being tackled during playing basketball and had a radial neck fracture. However, the diagnosis of her fracture was delayed for 3 weeks. At the first radiologic examination, the anteroposterior and lateral radiographs were showing over 80 degrees of angulation at the radial neck and subluxation of the radiocapitellar joint. We tried to obtain a closed reduction, but we could not succeed. Then, we performed open reduction while preserving medial periosteal continuity and vascular supply of the radial head by meticulous surgical dissection. Sixth-month radiography control and clinical examination confirmed the complete healing of the fracture without any epiphyseal injury. Painless full range of motion without any restriction of pronation and supination was achieved. The patient and her parents were satisfied with the outcome. Conclusions: Even if the diagnosis of pediatric radial fractures is delayed if we can preserve medial periosteal continuity and vascularity of the radial head with open reduction, satisfactory results are obtainable. Keywords: Pediatric, radial neck fracture, open reduction, late diagnosis.

Treatment Outcome of Métaizeau Technique of Intramedullary Pinning in Pediatric Displaced Radial Neck Fracture

Introduction: Displaced radial neck fracture in children when poorly managed results in deformity of elbow and incapacitates patient’s daily activities due to compromised forearm motion, hence they require careful attention. Aims: The aim of this study is to assess the outcome of Métaizeau Technique in displaced radial neck fracture in Children. Methods: This hospital based study evaluated the treatment outcome of 35 patients with an average age of 9.34 years (range, 6 – 14 years), who presented with displaced radial neck fracture; and were treated by Métaizeau technique of intramedullary pinning by Kirschners (K) wire at Nepalgunj Medical College, Kohalpur from April 2017 to January 2020. Only Judet’s type 3 and 4 fractures were included in this study. Close reduction was attempted in all cases. All patients were followed up for an average of 8.4 months (range, 6-12 months). Functional outcome was assessed as per Métaizeau functional score. Results: All fractures united at an average of 3.77 0.84 months (meanSD). Twenty seven patients had type 3 fracture and remaining 8 had type 4a fracture. Twenty five (92.5%) patients with type 3 fracture exhibited excellent results; while three patients (37.5%) with type 4a fracture had excellent outcome. Closed reduction produced excellent outcome in all patients while 80.95% patients with percutaneous reduction had excellent result. Conclusion: Outcome depends on initial fracture type and mode of reduction. Closed reduction should be preferred over an open reduction in order to achieve superior outcome.
