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.
