The coronavirus outbreak significantly changed the need of healthcare services. We hypothesized that COVID-19 pandemic decreased frequency pediatric fracture operations. also emergency surgical operations as well, a result patient-related reasons, such neglecting or underestimating symptoms, to avoid hospital admission.Nationwide data were individually collected and analyzed in all five tertiary surgical/trauma centers Finland. Operations related fractures, appendicitis, acute scrotum...

<b>Introduction</b> Forearm fractures are common among children. Unlike most pediatric fractures, there is a risk of unsatisfactory results in forearm shaft fractures. The healing tubular bone unlikely the diaphysis far away from metaphyseal zones. treatment evolving. purpose study was to analyze pattern and their population children recent years. <b>Materials Methods</b> All (from 0 16 years) with both-bone fracture (AO-segment 22-D) during years 1997 2009 catchment area about 86,000 were...

Proximal humerus fractures comprise approximately 2% of all pediatric fractures. In general, upper extremity have increased in children. However, recent trends proximal are not analyzed yet. The aim was to study the incidence and treatment children.All 300 children, aged < 16 years, who suffered from a fracture catchment area Oulu University Hospital, Finland, between 2005 2015, were included. Radiographs reviewed, patients, injuries, treatments, outcomes comprehensively studied. Annual...

Distal forearm is the most common fracture location in growing skeleton. The aim of this article to describe current practice these fractures.Case series accompanied by experts' opinion.Most injuries are benign incomplete distal metaphyseal torus fractures best treated with a dorsal below elbow splint for 2-3 weeks no follow-up. Completely displaced prepubertal children can be either immobilized bayonet position after axial alignment or fixed K-wires reduction. Complete metaphysis...

Background and purpose - Supracondylar humerus fractures are the most common type of elbow fracture in children. A small proportion them flexion-type fractures. We analyzed their current incidence, injury history, clinical radiographic findings, treatment, outcomes. Patients methods performed a population-based study, including all children <16 years age. Radiographs were re-analyzed to include only supracondylar Medical records reviewed outcomes evaluated at mean 9 after injury. In...

Posterior cranial vault distraction (PCVD) is a technique widely used in surgical treatment of craniosynostosis when expansion required. It has proven to be safe and allow significant increase intracranial volume.To evaluate increases volume as result PCVD performed Oulu Craniofacial center using 2 different methods based on 3-dimensional (3-D) photogrammetric imaging or plain skull radiographs.All children less than 16 yr age who were treated by (n = 31) from 2009 2015 at the Center...

The elbow is the joint that most usually dislocates in children. In contrast to widely known recent increase incidence of upper-extremity fractures and their operative treatment children, potential trends dislocation are not clear. this study we aimed clarify epidemiology childhood dislocation, particular change treatment. A population-based was performed evaluate annual characteristics injury, patients All children < 16 years age with an 1996–2014 Oulu University Hospital District, Finland,...

Background and purpose — The incidence of forearm shaft fractures in children has increased operative treatment compared with nonoperative recent years. We analyzed the long-term results treatment.Patients methods performed a population-based age- sex-matched case-control study Vaasa Central Hospital, concerning treated period 1995–1999. There were 47 nonoperatively both-bone fractures, patients all participated study. 1 healthy control per case was randomly selected evaluated for...

Background Supracondylar humerus fractures are usual in children but their recent trends unclear. Material and Methods A population-based study was performed to determine the epidemiology of childhood supracondylar during decade, 2000 2009, a geographic area Oulu, Finland. Altogether, 565 extension-type were included. The treatment analyzed according Gartland classification. Results Fracture incidence increased by 28%, from 50.9 65.2 per 100,000 2009 (β = 1.03, p &lt; 0.001). increase 41.3...

Background and Aim: Operative treatment is often indicated in unstable pediatric diaphyseal forearm fractures. Recently minimally invasive reduction elastic stable intramedullary nailing have been of increasing interest, instead open internal fixation with plates. There are several disadvantages metallic implants, such as soft-tissue irritation a risk disturbing later imaging. Thus, they generally removed operations. We aimed to develop new technique stabilize fractures by the bioabsorbable...
