Outcome of Monteggia Fracture Dislocation in Children Treated With K Wires in Nepalgunj Medical College

Introduction: Monteggia fracture dislocations are rare injuries (<5%) where missed treatment results into deformity and dysfunction of forearm and hand. For the better functional result early diagnosis, accurate reduction of radial head and rigid fixation of ulna and immobilization during post-operative period for ligamentous healing around radius is vital. So operative treatment has been the primary method of treatment to prevent deformity and disability in monteggia fracture dislocation. Aims: The aim of this study was to evaluate the time taken to unite fractures, complications encountered and assess the functional outcome on the basis of K-wire fixation in monteggia fracture dislocation in children. Methods: A cross-sectional observational study was conducted in Nepalgunj Medical College and Teaching Hospital, Kohalpur, Banke with monteggia fracture dislocation in children. Results: Thirty-two monteggia fracture dislocation in children between six to 14 years of age were treated with intramedullary K-wires after reduction of radial head. Seven cases had open reduction, and five needed trans-capitellar K-wire supplementation. Mean union time was 8.44±1.94 weeks ranging from seven to 12 weeks. The functional outcome on the basis of Anderson’s scoring system was excellent in 25(78.1%), good in three and optimal in four cases. Conclusion: Monteggia fracture dislocation is better treated early and early mobilization of elbow joint is needed for better functional results.

A Novel Case of Neglected Monteggia Fracture Dislocation

Background: The Monteggia fracture-dislocation is a rare condition among children, and its treatment is still controversial. The treatment can become quite complicated when the diagnosis is delayed. There is a broad range of surgical treatments with various complications like subluxations, degenerative changes, and radial head deformity. The present case was reported as a novel surgical treatment choice for neglected Monteggia fracture-dislocation. Case Report: A 16 year-old boy presented with left elbow severe range of motion (ROM) limitation and pain who was diagnosed with neglected Monteggia fracture-dislocation. The patient went through open reduction beside internal fixation of the ulnar shaft via Limited Contact Dynamic Compression Plate (LC-DCP) and radio-capitellar joint reduction and provisional fixation by a pin. The patient recovered after three months with a significant increase in elbow ROM without any complications. Conclusion: This method could be an appropriate treatment of choice for neglected Monteggia fractures which indeed had excellent outcomes without complication.

Surgical stabilization of traumatic elbow joint luxation and proximal ulnar fracture in a silvery langur (Trachypithecus cristatus)

CASE DESCRIPTION A 3-year-old 5-kg sexually intact female silvery langur housed in a single-species group at a zoological institution was presented because of acute trauma to the left forelimb. CLINICAL FINDINGS Radiography of the left forelimb revealed a type II Monteggia fracture (proximal ulnar fracture with cranial displacement and caudal luxation of the radial head). During surgery, disruption of the annular ligament and rupture of the lateral collateral ligament were noted. TREATMENT AND OUTCOME The langur underwent open reduction and internal fixation of the ulnar fracture and placement of a radioulnar positional screw, a prosthetic lateral collateral ligament, and a temporary hinged type 1A external skeletal fixator. The langur was returned to group housing, underwent behavioral training, and was periodically anesthetized for physical therapy sessions to improve range of motion of the left elbow joint. The external skeletal fixator was removed 4 weeks after surgery, and the radioulnar positional screw was removed 6 weeks after surgery. Three months after surgery, the range of motion of the langur’s left elbow joint was considered normal, and the animal returned to normal activity. CLINICAL RELEVANCE For the captive silvery langur of the present report, surgical stabilization and postoperative management of a type II Monteggia fracture of the left forelimb were successful with recovery of elbow joint function. These techniques may be applied to other captive nonhuman primates, including those that brachiate or are members of social species that must be housed with conspecifics in the postoperative period to maintain group dynamics.

Monteggia Variant with Salter-Harris Fracture of the Radial Head: Case Report and Litergature Review

Introduction:The Monteggia fracture is a fracture to the proximal third of ulna associated with a radial head dislocation. Although this is well described and classified in adults, it is uncommon in children. Identifying growth plate trauma and subsequent surgical management are of critical importance. This report identifies a unique variant of Monteggia fracture with a Salter-Harris Type I injury of the radial head instead of a dislocation, and how it was successfully stabilised with a closed reduction. Case Rport: We present a case of a nine 9 year-old female admitted to our unit with a deformed upper extremity following a fall from height. This was a closed and isolated injury without neurovascular compromise. Radiographs revealed a displaced fracture to the proximal ulna shaft. Unlike a true Monteggia, the radial fracture went through the proximal physis with anterior divergence of the distal fragment. The radiocapitellar joint remained congruent. The ulna fracture was stabilized with open reduction and plate osteosynthesis whilst the radial injury underwent closed reduction and intramedullary pinning with excellent outcomes and maintenance of full range of motion. Conclusion: This case highlights a new variant and successful outcome following a closed reduction intramedullary fixation technique in this emergent pattern of injury. We highlight the need for a classification of these fractures in children. Keywords: Case report, Monteggia, growth plate, pediatric, fracture, trauma, variant.

A New Pediatric Monteggia Fracture Type 4 Variant

Introduction: Monteggia fracture-dislocations are rare and complex injuries that usually involve a fracture of the proximal ulna associated with a proximal radioulnar and radiocapitellar joint dislocations. These injuries comprise <1% of all pediatric forearm fractures. We report on a pediatric Monteggia fracture-dislocation variant that included an irreducible divergent ulnohumeral joint dislocation, an irreducible anterior radial head dislocation, and a proximal and distal radius and ulna fracture. Case Report: A 6-year-old female came to our emergency room with a right elbow and forearm pain and deformity after a fall from a slide on the same day. X-rays revealed a divergent ulnohumeral joint dislocation, an anterior radiocapitellar joint dislocation, a proximal radioulnar joint dislocation, and a proximal and distal ulna and radius fracture. Closed reduction under sedation in the emergency room was not successful, with persistent ulnohumeral, ulnoradial, and radiocapitellar joint dislocations. The patient was taken to the operating room the next morning. She underwent open reduction and internal fixation of the proximal ulna fracture with a one-third tubular locking plate, and radial head dislocation open reduction. A stable reduction of the ulnohumeral joint was only possible after the fixation of the proximal ulna fracture. The most stable position for the radiocapitellar joint after its open reduction was at 70o of elbow extension and full forearm supination; the patient was casted in that position for 6 weeks. Conclusion: Pediatric Monteggia fracture-dislocations are rare and complex childhood fractures, and new variants of this injury can have even more complex presentations. Open reduction and stable internal fixation addressing all components of this injury will lead to an excellent outcome.

Osteotomia da ulna para correção cirúrgica de fratura de Monteggia negligenciada em criança com deformidade plástica da ulna. Relato de caso / Ulna osteotomy for surgical correction of neglected Monteggia fracture in a child with ulna bowing. Case report

Introdução: A luxação da cabeça do rádio com deformidade plástica da ulna, quando combinadas, configuram uma condição rara, e frequentemente não diagnosticada na urgência. Objetivo: Relatar um caso de fratura de Monteggia negligenciada em criança com defomidade plástica da ulna, tratada cirurgicamente com redução e fixação da cabeça dorádio, sem reconstrução do ligamento anular, e osteotomia da ulna. Relato do Caso: Paciente de 6 anos de idade, sexo masculino, vítima de queda ao solo com a mão espalmada, deu entrada em Unidade de Pronto Atendimento com queixa de dor no cotovelo direito. Paciente foi submetido à exames de imagem radiográficos do cotovelo interpretados peloexaminador como sem alterações. Duas semanas após, o paciente retornou mantendo dor, e foram solicitados exames de radiografia do antebraço, que evidenciaram presença de deformidade plástica da ulna associada à luxação da cabeça do rádio. Como tratamento, optou-se pela redução aberta e fixação da cabeça do rádio com fios metálicos, associado aosteotomia de flexão da ulna fixada com fio de Kirschnner. Evoluiu no pós operatório com consolidação da osteotomia, manutenção da redução da cabeça do rádio, e recuperação do arco de movimento total do cotovelo e antebraço. Conclusão: Pacientes pediátricos que se apresentam com dor no cotovelo, em decorrência de queda com a mão espalmada, devem ser minuciosamente avaliados quanto à possibilidade de deformidade plástica da ulna associada à luxação da cabeça do rádio. A osteotomia na ulna com fixação da cabeça do rádio, sem reconstrução do ligamento anular, trouxe bom resultado no tratamento de fratura de Monteggia negligenciada em criança com defomidade plástica da ulna. Palavras chave: Fratura de Monteggia, Ulna/deformidades, Fraturas da ulna, Osteotomia, Trauma, Criança, Pediatria Abstract Introduction: Dislocation of the radial head with ulna bowing, when combined, constitutes a rare condition, and often missed diagnosed. Objective: Report a case of neglected Monteggia fracture in a child with ulna bowing, treated surgically with reduction and fixation of the radial head, without reconstruction of the annular ligament, and osteotomy of the ulna. Case Report: A 6-year-old male patient, victim of falling to the ground, was admitted to the Emergency Department with complaints of pain in his right elbow. The patient was submitted to radiographic exams of the elbow, interpreted by the physician as normal. Two weeks later, the patient returned with pain, and radiographic exams of the forearm showed the presence of ulna bowing associated with dislocation of the radial head. As a treatment, we opted for open reduction and fixation of the radial head with metallic wires, associated with flexion osteotomy of the ulna. It evolved in the postoperative period with consolidation of the osteotomy, maintenance of the reduction of the radial head, and recovery of the total range of motion of the elbow and forearm. Conclusion: Pediatric patients who present with pain in the elbow, due to a fall, should be thoroughly evaluated for the possibility of ulna bowing associated with dislocation of the radial head. Ulna osteotomy with fixation of the radial head, without reconstruction of the annular ligament, brought good results in the treatment of neglected Monteggia fracture in a child with ulna bowing.
