The decision for operative or nonoperative treatment of pelvic ring injuries is based on:
Fracture stability, displacement, and pattern
Surgical skill and availability of equipment
Pelvic ring stability is assessed by the type and location of fractures and joint injuries involving the pelvic ring.
Goal of treatment
These fractures are stable fractures and typically do not require operative treatment. The exception is selected apophyseal avulsions. In these cases reduction and internal fixation is performed.
The goals of nonoperative treatment are:
Satisfactory fracture healing
Recovery of function
In an appropriate time frame
Mobilization can often begin early but should be individualized. Even in a bed bound patient, exercises to avoid stiffness and promote muscle function are advisable.
As soon as the patient is mobile enough, and comfortable enough, discharge from hospital should be possible and encouraged (depending upon other injuries).
Weight bearing must be individualized but initial protection, using crutches or a walker, is advocated. This can be gradually decreased as comfort and healing permit.
Most of these pelvic fractures become increasingly stable by 6 weeks, and most are securely healed by 3 months. A helpful approach is to accept permissive weight bearing, permitting the patient to bear weight according to tolerance.
Outpatient rehabilitation should maintain and increase mobility and muscle strength. Contractures should be avoided.
Patients should be seen at 2 weeks, 6 weeks, and 3 months after injury. Follow up X-rays are obtained at these visits to assess fracture healing.
Patients with persistent pain (especially low back pain), require special attention to exclude undiagnosed unstable fracture patterns, and/or nonunions. If pain has not resolved by 3 months or more, CT scans or other advanced imaging may be advisable.
