An Adolescent Patient With Hip Pain: Slipped Capital Femoral Epiphysis

.He had a moderate antalgic gait with the left leg in external and internal rotation. He had also showed limited mobility of left hip in abduction, with no edema or crepitation and sensory or motor defi cits. The examination of the contralateral hip was unremarkable. The anteroposterior hip radiograph showed increased left hip joint space compared to the right hip (Fig. 1). A frog-leg lateral left hip radiograph demonstrated dislocated capital femoral epiphysis on the proximal femoral metaphysis (Fig. 2). He was taken to surgery with the diagnosis of slipped capital femoral epiphysis and the right femoral epiphysis internally fi xed with a single-cannulated screw under scopy guidance. Slipped capital femoral epiphysis (SCFE), also named as adolescent coxa vara, is characterized by a growth disturbance of the proximal femoral growth plate, resulting in posterior and inferior displacement of the proximal femoral epiphysis (femoral head) on the metaphysis (femoral neck) [1, 2]. It is a common hip disorder which is known to be strongly related to overweight and obesity in adolescents and children aged 9 - 16 years [1, 3]. A retrospective review of emergency department records stated that 68% of children with SCFE had body mass index above the 95th percentile mean weight for age [2]. The most frequent presenting symptoms in patients with SCFE are pain in the affected hip, groin, thigh, or
