Abstract

Avulsion injuries of the anterior inferior iliac spine, which is the origin of the rectus femoris muscle, are sometimes reported in children and adolescents, but acute avulsion injuries with complete rupture of the rectus femoris are very rare in adults. We treated a case of avulsion fracture of the anterior inferior iliac spine with suture anchors in an adult and achieved a favorable outcome. Thus, we report the case with a review of literature.

Figure

• 

  Fig. 1. Simple AP radiograph shows an avulsed bone fragment displaced inferiorly from the right anterior inferior iliac spine (arrow).

• 

  Fig. 2. T2-weighted coronal magnetic resonance image shows complete avulsion of the direct head of the right rectus femoris muscle (arrow) and severe edematous change (arrow heads).

• 

  Fig. 3. During the operation, the detached bone fragment from the anterior inferior iliac spine is seen between the tensor fasciae latae and the sartorius, with the rectus femoris distally displaced by 2.5 cm (arrow).

• 

  Fig. 4. The displaced fragment was reduced with two suture anchors through the modified Kessler technique (arrow).

• 

  Fig. 5. Simple AP radiograph checked 4 months after the operation shows a healed avulsed bony fragment without inferior displacement (arrow).

• 

  Fig. 6. T2-weighted coronal magnetic resonance image checked 4 months after the operation shows anatomical restoration of the direct head of the right rectus femoris muscle (arrow).
