[Surgical treatment for rotationally and vertically unstable pelvis fracture]

To study the clinical results of surgery for rotationally and vertically unstable pelvis fracture.

Thirty-four patients with rotationally and vertically unstable pelvis fractures were treated. There were 23 male and 11 female,with the average age of 36 years ranging from 13 to 56 years. There were 9 cases of type APC III, 14 cases of type LC III, and 11 cases of type VS according to Young-Burgess Classifiction. All patients' pelvis were treated with temporary external fixation after hospitalization, and were treated with open reduction and internal fixation through anterior approach after stabilization of body condition.

All patients were followed up for 12 to 48 months (average 21 months). All the incisions healed well, and the fractures got union for 3 to 6 months. According to the Majeed evaluation, the results were excellent in 21 cases, good in 10, fair in 3. All patients were not remained deformity of rotation and dislocation. But 3 patients remained lameness, 4 remained low back pain, 3 remained both leg and feet numbness.

In the management of the rotationally and vertically unstable pelvis fractures, a stable pelvis can be reconstructed by effective open reduction and internal fixation through the anterior approaches, so that further sequelae can be reduced.
