This has been described after conservative treatment, but it has also been detected after surgical management. A frequent observation after treatment of proximal metaphyseal tibia fracture is the occurrence of progressive valgus deformity. Non-displaced fractures are usually treated conservatively, and in displaced fractures surgical treatment and osteosynthesis is generally performed. in 1953 -have a low incidence with 5.6 in every 100,000 children per year. Proximal metaphyseal tibia fractures-as first described by Cozen et al. Further studies are needed to explain the responsible mechanisms. Therefore, surgery for proximal greenstick fractures of the tibia in this age group has only limited effect and may be indicated only in selected cases. In surgically treated patients, progressive valgus was observed after metal removal for an unknown reason. In non-surgically treated patients, this was of statistical, but not clinical significance. Progressive valgus deformity after greenstick fractures of the proximal tibia occurred in both non-surgically and surgically treated patients. In surgically treated patients, the MTPA improved after trauma to st-FU (94.00° p = 0.290), and increased again to lt-FU (96.41° p = 0.618). The MPTA in non-surgically treated patients significantly increased from the timepoint of trauma to st-FU (92,0° p = 0.030), and lt-FU (92,66°, p = 0.016). The mean MPTA at trauma of non-surgically treated patients was 91.14°, and of surgically treated patients was 95.59° ( p = 0.020). Of these, 74 were treated non-surgically and 17 were treated surgically. Of a total of 322 fractures, 91 were greenstick fractures. In patients with greenstick fractures, the medial proximal tibia angle (MPTA defined as the angle of the tibial axis and the joint-line of the knee) was measured at trauma, short-term follow-up (st-FU), and long-term FU (lt-FU) as defined for the 2 groups of non-surgically and surgically treated patients. MethodsĪ retrospective multi-center study was conducted including surveys and X-rays of patients < 12 years of age with a fracture of the proximal tibia. Greenstick tibial fracture Lower limb Pediatric trauma Progressive valgus deformity Proximal tibial fracture.This study investigates the occurrence of (progressive) posttraumatic valgus deformity after proximal metaphyseal greenstick fractures of the tibia in young children, and whether non-surgical or surgical treatment influences the outcome. In surgically treated patients, the MTPA improved after trauma to st-FU (94.00° p = 0.290), and increased again to lt-FU (96.41° p = 0.618).
