One in Three of Pediatric Tibia Shaft Fractures is Currently Treated Operatively : A 6-Year Epidemiological Study in two University Hospitals in Finland Treatment of Pediatric Tibia Shaft Fractures

Background: Internal fixation of pediatric tibia shaft fractures has become increasingly popular despite the fact that non-operative treatment results in satisfactory outcome with few exceptions. Indications for surgery and benefits of internal fixation are however still debatable. Materials and Methods: All 296 less than 16-year-old patients treated for a tibia shaft fracture between 2010 and 2015 in two of the five university hospitals in Finland were included in the study. Patient data were analyzed in three treatment groups: cast immobilization in emergency department, manipulation under anesthesia, and operative treatment. Incidence of operative treatment of pediatric tibia shaft fractures was calculated in the cities of Helsinki and Kuopio. Results: A total of 143 (47.3%) children's tibia shaft fractures were treated with casting in emergency department, 71 (22.3%) with manipulation under anesthesia, and 82 (30.4%) with surgery. Mean age of the patients in these treatment groups was 6.2, 8.7, and 12.7 years. Fibula was intact in 89%, 51%, and 27% of the patients, respectively. All 6 patients with multiple fractures and 16 of 18 patients with open fractures were treated operatively. In eight patients, primary non-operative treatment was converted to internal fixation. Operatively treated patients with isolated closed fractures were more likely to have a fibula fracture (46/66 vs 52/214, p <0.001), be older in age (13.08 2.4 vs 6.4 +/- 3.7, p <0.001), and have more primary angulation (6.9 +/- 5.8 vs 0.48 +/- 3.1, p <0.001). Re-operations were done to eight and corrective osteotomy to two operatively treated children. Conclusion: Operative treatment of a pediatric tibia shaft fracture is currently nearly a rule in patients with open or multiple fractures. Surgical treatment of closed tibia shaft fractures is based on surgeon's personal preference, type of fracture and age of the patient.Peer reviewe

9 years' follow-up of 168 pin-fixed supracondylar humerus fractures in children

Background and purpose - The long-term outcome of pin-fixed supracondylar humerus fractures (SCHF) in children is not well known. We assessed the 7- to 12-year outcome in 168 children. Patients and methods - During 2002-2006, 210 domestic children (age 7 (1-14) years) with SCHF (Gartland III 79%, Gartland II 19%, and flexion type 2%) were pin fixed in Helsinki. 36 (17%) patients had a nerve palsy. Radiographic alignment was regarded as satisfactory in 81% of patients (Baumann angle (BA) within 10 of normal range and whose anterior humeral line (AHL) crossed the capitulum). After a mean follow-up of 9 (7-12) years, 168 (80%) patients answered a questionnaire regarding elbow appearance (scale 0-10), function (scale 0-10), and pain (scale 0-10), and symmetry of range of motion (ROM) and carrying angle (CA). 65 (31%) patients also attended a clinical follow-up examination. Results - Mean subjective score for appearance was 8.7 (2-10) and for function 9.0 (2-10) (n = 168). Elbow ROM asymmetry was experienced by 28% and elbow CA asymmetry by 17% of the patients. Elbow pain was reported by 14%, and was more common in children with nerve injuries. Long-term outcome was good or excellent in 60/65 and CA in 56/65 of the follow-up visit patients using Flynn's criteria. BA exceeding normal values by 10 was associated with lower subjective outcome; AHL crossing point with the capitulum was not associated with outcome. Interpretation - Long-term subjective outcome is satisfactory with few exceptions if elbow ROM and CA are restored within 10 degrees of the uninjured elbow. Radiographs at fracture union have little prognostic value. Nerve injuries can cause long-term pain.Peer reviewe

Hospital admissions and surgical treatment of children with lower-limb deficiency in Finland

Background and Aims: There are no population-based studies about hospital admissions and need for surgical treatment of congenital lower-limb deficiencies. The aim is to assess the impact children with lower-limb deficiencies pose to national hospital level health-care system. Materials and Methods: A population-based study was conducted using the national Register of Congenital Malformations and Care Register for Health Care. All 185 live births with lower-limb deficiency (1993-2008) were included. Data on hospital care were collected until 31 December 2009 and compared to data on the whole pediatric population (0.9 million) live born in 1993-2008. Results: The whole pediatric population had annually on average 0.10 hospital admissions and the mean length of in-patient care of 0.3 days per child. The respective figures were 1.5 and 5.6 in terminal lower-limb amputations (n = 7), 1.1 and 3.9 in long-bone deficiencies (n = 53), 0.6 and 1.9 in foot deficiencies (n = 26) and 0.4 and 2.6 in toe deficiencies (n = 101). Orthopedic surgery was performed in 72% (5/7) of patients with terminal amputations, in 62% (33/53) of patients with long bone, in 58% (14/24) of patients with foot and in 25% (25/101) of patients in toe deficiencies. Half (54%) of all procedures were orthopedic operations. Conclusion: In congenital lower-limb deficiencies the need of hospital care and the number of orthopedic procedures is multiple-fold compared to whole pediatric population. The burden to the patient and to the families is markedly increased, especially in children with terminal amputations and long-bone deficiencies of lower limbs.Peer reviewe

Treatment of Aneurysmal Bone Cysts with Bioactive Glass in Children

Background and Aims: Aneurysmal bone cysts represent about 1% of primary bone tumors. The standard treatment is curettage, followed by local adjuvant treatments and bone grafting. The problem is the high recurrence rate. The purpose of this study was to evaluate retrospectively the use of bioactive glass as a filling material in the treatment of aneurysmatic bone cysts in children. Material and Methods: A total of 18 consecutive children (mean 11.3years at surgery; 10 males; 11 lower, 6 upper limb, 1 pelvis; 15 with primary surgery) with histologically proven primary aneurysmal bone cysts operated with curettage and bioactive glass filling between 2008 and 2013 were evaluated after a mean follow-up of 2.0years (range, 0.7-5.1years). Results: Two (11%) patients showed evidence of aneurysmal bone cyst recurrence and both have been re-operated for recurrence. Bone remodeling was noted in all patients with remaining growth and no growth plate disturbances were recorded. Two patients needed allogeneic blood transfusion. No intraoperative or postoperative complications were recorded. Conclusion: We conclude that bioactive glass is a suitable filling material for children with primary aneurysmal bone cyst. Bioactive glass did not affect bone growth and no side effects were reported.Peer reviewe

Outcome after pin fixation of supracondylar humerus fractures in children : postoperative radiographic examinations are unnecessary A retrospective study of 252 Gartland-III and 12 flexion-type supracondylar humerus fractures

Background and purpose - The quality of pin fixation of displaced supracondylar humerus fractures in children has not been assessed, and the clinical value of radiographic examinations after pin fixation is unclear. We evaluated pin configuration, quality of osteosynthesis, and outcome in 264 supracondylar fractures. The clinical significance of postoperative radiographs was analyzed. Patients and methods - 252 Gartland-III and 12 flexion-type supracondylar humerus fractures were pin-fixed in the periods 2002-2006 and 2012-2014. During 2012-2014, staff were intructed that postoperative radiographs should not be taken. Quality of reduction was assessed by measuring Baumann and lateral capitellohumeral angles (LCHA) and also by recording the crossing point of the anterior humeral line (AHL) with bony capitellum. Rotatory alignment was registered as normal or abnormal. Pin configuration and quality of osteosynthesis were evaluated. The clinical significance of postoperative radiographs was analyzed. Results - Postoperatively, Baumann angle was normal in 66% of the fractures, AHL crossed the capitellum in 84%, and no malrotation was evident in 85% of the fractures. Crossed pins were used in 89% of the cases. 2 or more pins fixed both fracture fragments in 66%. Radiographic examinations were inadequate for assessment of LCHA in 13%, of Bauman angle in 8%, of AHL in 2%, of rotation in 1%, and of pin fixation in 2% of the cases. Postoperative radiographs did not give useful information except in 1 patient who had corrective osteotomy. All 94 patients with follow-up (97%) who were treated during 2012-2014 were satisfied with the outcome. Interpretation - Despite pin fixation being deemed unsatisfactory in one-third of the cases, significant malunion was rare. Postoperative radiography did not alter management or outcome.Peer reviewe

The feasibility of a randomised control trial to assess physiotherapy against surgery for recurrent patellar instability

Background: Patellar instability is a relatively common condition that leads to disability and restriction of activities. People with recurrent instability may be given the option of physiotherapy or surgery though this is largely driven by clinician preference rather than by a strong evidence base. We sought to determine the feasibility of conducting a definitive trial comparing physiotherapy with surgical treatment for people with recurrent patellar instability. Methods: This was a pragmatic, open-label, two-arm feasibility randomised control trial (RCT) with an embedded interview component recruiting across three NHS sites comparing surgical treatment to a package of best conservative care; 'Personalised Knee Therapy' (PKT). The primary feasibility outcome was the recruitment rate per centre (expected rate 1 to 1.5 participants recruited each month). Secondary outcomes included the rate of follow-up (over 80% expected at 12 months) and a series of participant-reported outcomes taken at 3, 6 and 12 months following randomisation, including the Norwich Patellar Instability Score (NPIS), the Kujala Patellofemoral Disorder Score (KPDS), EuroQol-5D-5L, self-reported global assessment of change, satisfaction at each time point and resources use. Results: We recruited 19 participants. Of these, 18 participants (95%) were followed-up at 12 months and 1 (5%) withdrew. One centre recruited at just over one case per month, one centre was unable to recruit, and one centre recruited at over one case per month after a change in participant screening approach. Ten participants were allocated into the PKT arm, with nine to the surgical arm. Mean Norwich Patellar Instability Score improved from 40.6 (standard deviation 22.1) to 28.2 (SD 25.4) from baseline to 12 months. Conclusion: This feasibility trial identified a number of challenges and required a series of changes to ensure adequate recruitment and follow-up. These changes helped achieve a sufficient recruitment and follow-up rate. The revised trial design is feasible to be conducted as a definitive trial to answer this important clinical question for people with chronic patellar instability. Trial registration: The trial was prospectively registered on the International Standard Randomised Controlled Trial Number registry on the 22/12/2016 (reference number: ISRCTN14950321). http://www.isrctn.com/ISRCTN1495032

Reduced Number of Pediatric Orthopedic Trauma Requiring Operative Treatment during COVID-19 Restrictions: A Nationwide Cohort Study

Background and Aims:The coronavirus outbreak significantly changed the need of healthcare services. We hypothesized that the COVID-19 pandemic decreased the frequency of pediatric fracture operations. We also hypothesized that the frequency of emergency pediatric surgical operations decreased as well, as a result of patient-related reasons, such as neglecting or underestimating the symptoms, to avoid hospital admission.Materials and Methods:Nationwide data were individually collected and analyzed in all five tertiary pediatric surgical/trauma centers in Finland. Operations related to fractures, appendicitis, and acute scrotum in children aged above 16 years between March 1 and May 31 from 2017 to 2020 were identified. The monthly frequencies of operations and type of traumas were compared between prepandemic 3 years and 2020.Results:Altogether, 1755 patients were identified in five tertiary hospitals who had an emergency operation during the investigation period. There was a significant decrease (31%, p = 0.03) in trauma operations. It was mostly due to reduction in lower limb trauma operations (32%, p = 0.006). Daycare, school, and organized sports-related injuries decreased significantly during the pandemic. These reductions were observed in March and in April. The frequencies of appendectomies and scrotal explorations remained constant.Conclusion:According to the postulation, a great decrease in the need of trauma operations was observed during the peak of COVID-19 pandemic. In the future, in case similar public restrictions are ordered, the spared resources could be deployed to other clinical areas. However, the need of pediatric surgical emergencies held stable during the COVID-19 restrictions
