A Shift From Non-operative Care to Surgical Fixation of Pediatric Humeral Shaft Fractures Even Though Their Severity Has Not Changed

Pediatric Humeral Shaft Fracture Nonunion: A Case Report

Humeral shaft fractures in the pediatric population are a commonly encountered injury in everyday practice. Most patients with these injuries are treated without surgery and go on to have an uneventful recovery. Nonunion of these injuries in the pediatric population has been reported only once in the literature. This case report follows a 13-year-old female after a seemingly standard transverse humeral shaft fracture. The patient was treated with a fracture brace initially. No signs of healing were noted at the eight-week post-injury follow-up. The family elected for continued conservative management until the patient returned at four months post-injury with persistent gross motion at the fracture site and no healing on radiographs. Laboratory testing did show that she has mild-to-moderate vitamin D deficiency, which was addressed. The patient underwent nonunion treatment with open reduction, internal fixation, and bone grafting. She went on to full union with an uncomplicated postoperative course. This case presents an interesting and unique case presentation. This report shows that, while rare, it is a potential outcome of humeral shaft fractures in the pediatric population. This case also demonstrates that using the standard adult operative technique for nonunion treatment with rigid internal fixation and bone grafting in a pediatric patient will lead to full-bone healing.

Epidemiological Investigation of Pediatric Fractures-A Retrospective Cohort Study of 1129 Patients

Background and Objectives: Fractures are common in pediatric trauma, and they are caused by a broad spectrum of factors. Only a few studies have discussed the mechanisms of injury and their relationships to different types of fractures. The most frequent type of fractures in different age groups remains unclear. Therefore, we aim to summarize the epidemiological characteristics of pediatric fractures in a medical center in Zhuhai, China from 2006 to 2021 and analyze the causes of fractures with the highest frequency in different age groups. Materials and Methods: We extracted the information from the Zhuhai Center for Maternal and Child Health Care of those under 14 years old who had fractures from 2006 to 2021. Results: We reviewed the information of 1145 children. The number of patients increased during the 15 years (p < 0.0001). The number of patients was significantly different between genders after Y2 (p = 0.014). In addition, more than two-thirds of patients (71.3%) had upper limb fractures, and all types of falls were the most common cause of fractures (83.6%). The incidence demonstrated an insignificant difference in age groups except for the fractures of humerus and radius. Moreover, we discovered that the prevalence of fall-related injuries decreased with age, while that of sports-related injuries increased with age. Conclusions: Our study demonstrates that the prevalence of fall-related injuries decreases with age, and that of sports-related injuries increases with age. Most patients have upper limb fractures, and all types of falls are the most common cause of fractures. Fracture types with the highest frequency differ in each age group. These findings might supplement current epidemiological knowledge of childhood fracture and provide references for decision-making in children's health policies.

Evaluation and Management of Pediatric Humeral Shaft Fractures

Diaphyseal humerus fractures in the pediatric population have dynamic treatment strategies that depend on injury pattern, mechanism, patient skeletal maturity, and size. Treatment strategies include closed reduction with various immobilization techniques, flexible nails, uniplanar or multiplanar external fixation, or plate osteosynthesis. Accepted parameters for sagittal and coronal alignment vary based on age and potential for remodeling, and the multiplanar motion of the shoulder joint can accommodate for greater variations in alignment than many other long bone fractures. Complications such as radial nerve palsy are possible with both open and closed injuries, and mal/nonunions, although rare, can occur. Overall, treatment should be predicated on a full evaluation of the patient, fracture, local soft tissues, and any concomitant injuries.

Changes in the management of pediatric medial humeral epicondyle fractures with and without associated elbow dislocation

Purpose The optimal management of medial humeral epicondyle fractures continues to be debated since decades. This single center study analyzes changes and optimizations of treatment over an observation period of 16 years and reports the results. Materials and Methods Retrospective analysis of all patients treated with a medial humeral epicondyle fracture between 2005 and 2020 at our institution. Results Ninety-six patients (mean 9.3 years, range 1 - 15) were included in the study. In 25 cases (26 %), the fracture was associated with an elbow dislocation. Most patients received surgical treatment (83.3 %), whereas 17.7 % were treated nonoperatively. Surgical treatment consisted of open reduction and fixation with compression screw (n = 44 steel, n = 2 absorbable), K-wire (n = 30), a combination of screw/K-wire (n = 2), or a PDS suture (n = 1). Compression screws have been used significantly more often in the latter half of the study period (p = 0.006). Patients were immobilized in a long arm cast for 29 days (range 11 - 50). Eleven surgically treated patients were early mobilized in an elbow orthosis. After a mean follow up of 7.6 months [2 - 61), Mayo elbow performance index (MEPI) outcome was excellent in all 96 patients. Loss of elbow movement (LOM) was found to be mild in 30 and moderate in 15 patients. LOM was found to be associated with surgical treatment (p = 0.001), and with concomitant elbow dislocations (p = 0.29). One pseudarthrosis occurred after conservative treatment. A persistence of ulnar nerve palsy or recurrent joint instability has not been described. Conclusion Most children with medial humeral epicondyle fractures nowadays undergo surgery. Screw osteosynthesis represents the increasingly preferred method in order to prevent joint instability or non-union, and to allow shorter immobilization duration. Overall results after medial epicondyle fractures are good.
