RATIONALE: The purpose of this study was to estimate the efficacy and safety of percutaneous periacetabular screw (PPS) insertion assisted by screw view model of navigation (SVMN) to treat fracture of acetabulum.
PATIENT CONCERNS: A 61-year-old male patient was injured in a motorcycle accident, which caused pain, swelling, deformity and limited mobility on his right hip.
DIAGNOSES: He was diagnosed with fracture of acetabulum.
INTERVENTIONS: We used PPS insertion assisted by SVMN to treat fracture of acetabulum in this patient.
OUTCOMES: The follow up lasted 24 months. Totally 2 screws were inserted into anterior and posterior column of acetabulum respectively and both of them displayed grade 0. Compared with the preoperative gap and step of fracture displacement, the postoperative ones were significantly reduced. It took 11.7 minutes for designing the screws, 6.7 minutes for implanting the guide wire, and 45.5 minutes for placing the screws. Intraoperative blood loss was 29 mL and total fluoroscopic time was 4.1 minutes. No clinical complications such as nerve vascular injury, infection and screw loosening were found after the operation.
LESSONS: The study indicated that SVMN is favorable to the PPS insertion for acetabular fracture. Our lesson is that the relative position between the acetabular and the patient tracker must be static to ensure the accuracy of the entire system throughout the operation.
