Abstract

Acetabular fractures can be treated with variable method. In this study, acetabular posterior wall fracture was treated with arthroscopic reduction and fixation using cannulated screw. The patient recovered immediately and had a satisfactory outcome. In some case of acetabular fracture could be good indication with additional advantages of joint debridement and loose body removal. So, we report our case with technical note.

• 

  Fig. 1 Left acetabular posterior wall fracture was seen in obturator foramen view.

• 

  Fig. 2 Arthroscopic images. (A) Fracture site was seen with haematoma. (B) The fracture fragment (arrows) of the acetabular posterior wall was visualized after haematoma evacuation.

• 

  Fig. 3 (A) A 4.0-mm-diameter cannulated screws was fixated. (B) Reduced fracture site under direct arthroscopic visualization.

• 

  Fig. 4 (A) Postoperative axial computed tomography image. (B) Obturator foreman view and (C) postoperative 6 months later view.

• 

  Fig. 5 Right acetabular posterior wall fracture was seen in anterior-posterior (AP) and obturator foramen view. (C) Right femur shaft fracture was seen in AP view.

• 

  Fig. 6 Arthroscopic image fracture site was seen with haematoma.

• 

  Fig. 7 (A) Postoperative anterior-posterior (AP) and (B) obturator foramen view. (C) Femoral shaft fracture site after intramedullary nail system in c-arm image and (D) post traction AP view.

• 

  Fig. 8 Second look arthroscopic image. Acetabular posterior wall fracture was healed completely.

• 

  Fig. 9 (A) Right acetabulum posterior wall fracture was seen in obturator foramen view. (B) Intraoperative C-arm image. The size and shape of obturator foramen was similar with preoperative radiograph.
