Quadrilateral plate fractures of the acetabulum: Classification, approach, implant therapy and related research progress

Table 2 Our recommendations for the treatment of quadrilateral plate fractures based on the Yang et al[14] classification hypothesis

	Ilioinguinal approach	Modified stoppa approach	Pararectus approach
Type A			Recommended
Type B	Recommended
Type C		Recommended (sometimes an iliac fossa approach can be combined)

We divided the line from the ischial spine to the iliopubic eminence in the QP into two parts (refer to Figure 1D). Type A: The fracture line involving the posterior half of the QP (refer to Figure 1D); Type B: The fracture line involving the anterior half of the QP(refer to Figure 1D); Type C: The fracture lines involving both the posterior and anterior half of the QP (refer to Figure 1D); QP: Quadrilateral plate.
