Traumatic Obturator Internus and Quadratus Femoris Injury in a Pediatric Patient: A Case Report

Abstract

We present the case of a 11-year-old White female patient with a traumatic quadratus femoris and obturator internus tear after a sprint while at school. She felt immediate pain, swelling, and point tenderness in her posterosuperior thigh with a severely antalgic gait. Magnetic resonance imaging demonstrated a quadratus femoris tear, obturator internus tear, and ischial spine avulsion fracture. Although a less common etiology for acute hip pain in the pediatric population, traumatic injury to the short external rotators should not be excluded. The prognosis is favorable with a full return to previous activities expected using an appropriate rehabilitation program.

Isolated Obturator Internus Muscle Strain Injury in a Professional Football Player: A Case Report

“…The main action of the obturator internus is the external rotation of the femur when the hip is in a neutral position and at a 90° flexion. Its secondary action is the adduction of the femur when the hip is in flexion [ 4 ]. The obturator internus muscle can be considered as a single functional unit together with the superior and inferior gemellus as well as the obturator externus muscle.…”

“…After literature research, there are only 10 reports of obturator internus strains in ball-kicking sports [ 2 , 3 , 5 , 6 , 7 , 8 , 9 ]. One report concerns a young ski athlete [ 10 ] and one report concerns an 11-year-old child during a sprint at school [ 4 ]. Only a few of these cases report an isolated obturator internus strain.…”
