In our hospital, we have been treating unstable type III & IV intra-articular fractures of the femoral neck (by Garden's classification) using our own original technique employing 3-hook pins. Here we selected and evaluated 48 cases in which we judged that intra operative reduction of the fracture had been performed correctly.
Good functional results were noted in 44 cases where fixation of the fractured bones had been complete during the operation. However among the remaining 4 cases, the fracture was classified as Minamizawa type III in 1 case, and type IV in 3.
We consider that Minamizawa type IV femoral neck fracture may be more amenable to an end-prosthesis than to osteosynthesis, whereas for type I and II cases, good operative results can be expected with our 3-hook pin technique if the fractured bones are reduced correctly during surgery.
