Abstract

Regardless of the efforts of several treatments after pelvic bone fracture, as many as 5% of all pelvic fractures result in malunion or nonunion of the pelvis. These complications can cause disabling symptoms, including pain, instability, and gait disturbance, which can decrease life quality of patients and increase socioeconomic problems. Therefore concerns regarding the treatment of malunion and nonunion after pelvic bone fracture are increasing. We report our experience and surgical management for pelvic malunion and nonunion.

Figure

• 

  Fig. 1 Correction of malunion and nonunion after pelvic bone fracture can be achieved with a variety of bone clamps and reduction forceps.

• 

  Fig. 2 Radiographs show posterior translation of the left hemipelvis on anteroposterior and inlet view and 5.5 cm significant superior migration of the left hemipelvis on outlet view. LLD: limb length discrepancy.

• 

  Fig. 3 Two-dimensional computed tomography shows nonunion through the left sacrum and left pubic ramus and 20 degree internal rotation deformity.

• 

  Fig. 4 Three-dimensional computed tomography shows superior and posterior migration along with internal rotation and flexion deformity of the left hemipelvis.

• 

  Fig. 5 Clinical photograph shows the posterior approach to the nonunion site of the sacrum and osteotomy at the site of nonunion.

• 

  Fig. 6 (A) Immediate postoperative pelvis anteroposterior radiograph shows correction of superior migration and internal rotation of the left hemipelvis. (B) Radiograph taken four years after reconstruction shows a well united osteotomy site without complications.
