Cronin PK, et al. - Between January 2000 and January 2014, 130 skeletally mature patients with 130 fractures (78 garden 1 and 52 garden 2) were analyzed to evaluate the final displacement after in situ percutaneous pinning for Garden type 1 and 2 fractures in height, femoral neck fracture collapse, and loss of offset in this retrospectively reviewed case series. They observed maximal collapse in the plane of the femoral neck. They noticed that 42% of Garden 1 fractures and 63% of Garden 2 fractures revealed >10 mm fracture collapse.
