Forty-nine children between the ages of 2 and 10 years, treated conservatively for fomoral shaft fracture, were studied clinically and radiographically to access the complications and related factors. They had an average follow-up of 48.8months(range, 12 to 77months). 35 percent of the patients had significant associated injuries. Leg length discrepancies of 10mm to 20mm are observed in 5 cases(10%) of the patients. The average overlap of bone ends at union was 6.5mm. The average growth acceleration was 8.8mm regardless of sex, age, upper limb dominance, fracture site or shape, but was promoted by overriding of the fracture ends at union, There were 16 cases(32%) of excessive angular deformity of 10° to 25° after union. However all deformities were remodelled enough to give normal alignment of the joint surface. The growth plate played on important role in the remodelling process.
